Boston High School: Tyler Whitney
Lawrence, Berkshire, KU take NEPSAC titles
March, 4, 2012
By Marc Thaler | ESPNBoston.com
SALEM, N.H. -- If coach Kevin Potter was nervous before his Lawrence Academy boys' hockey team took the ice Sunday, he didn't show it while chatting in the media room before the puck dropped.
Potter's players didn't skate like the moment was too much for them to handle, either.
Harvard-bound forward Devin Tringale buried the eventual game-winning goal 18 seconds before the second intermission, classmate Nate Heilbron protected the lead to perfection in a pulsating third period, and the fourth-seeded Spartans knocked off No. 2 seed Noble & Greenough, 3-2, to capture the New England Prep School Ice Hockey Association tournament championship.
"We're a veteran team. I said, 'Let's not worry about Nobles. Let's worry about how we play," said Potter, whose program, like Nobles, sought its first title in the high-stakes Stuart/Corkery tourney at the Icenter. "Except for the second period against Belmont Hill, out of the nine periods, we played our game. We dictated."
LA also capitalized on Nobles' costly defensive breakdowns.
Perfect example: a span of 2 minutes, 25 seconds late in the second period. That's when LA struck twice to turn a one-goal deficit into the lead Heilbron was charged with protecting.
"That was huge. We always talk about the last 2 minutes of every period being important," Potter said. "To get those two big goals there … that was big time."
First-line wingers Tyler Whitney and Tringale fueled the surge watched by a full house, including more than 50 coaches from the college and professional ranks.
Whitney's one-timer from the back side was set up by Tringale's decision to hold the puck low in the left-wing circle. Conor Maher (30 saves) was forced to hold his position near the right post.
Tringale slipped the pass to his linemate for the open look. Tie game with 2:43 until the break.
Courtesy of the to-be Crimson skater, the contest didn't stay tied for long. Tringale teamed with Whitney and William Messa to generate the go-ahead goal with 18 seconds on the clock.
"Messa kept the puck in on the forecheck," LA's 6-foot 1-inch, 195-pound winger said. "He made a nice pass to Ty Whitney, who made a really nice dish to me. It was just me and the goalie, and I went 5-hole."
Tringale's tally capped a tremendous swing in momentum. Nobles answered the game's first goal, a first-period marker by Matthew Baldino, with two scores.
Cal Burke capitalized on LA's lone mistake of the opening stanza: a defensive zone turnover.
Will Sleeper gave Nobles its only lead barely 3 minutes after the first break. Heilbron's kick-save generated a rebound that Sleeper stuffed home.
Midway through the period, Colin White had a quality chance to dig LA a deeper hole. He used his body and a burst of speed to gain a step on Robert Klein. But Heilbron's left leg denied a low shot from the right-wing circle.
The save sparked LA, which increased its intensity in the offensive zone. It led to the two-goal flurry that altered momentum.
"We didn't have a very good last three-and-a-half minutes in the second period, obviously," Nobles coach Brian Day said. "That was the difference in the game."
Heilbron (28 saves) was a difference-maker, too.
Outshot through two periods, 26-14, the Bulldogs fired 16 of the third period's 23 total shots. Several attempts were within feet of LA's stopper, who wasn't fooled once.
"They put a lot of pressure on us. They threw a lot of pucks to the net. They gave us everything they had," Heilbron said. "But my team and I, we stuck in there. We played our hearts out."
Of the many near-markers Nobles launched, none came closer to lighting the lamp than PJ Falvey's blast from the left point. Falvey fired into heavy traffic, and a tremendous screen from teammate Max Franklin.
Heilbron, somehow, never lost sight of the puck. He gloved it, with Franklin towering over him.
In the end, though, no team this season is towering over Lawrence Academy.
"It's crazy," Tringale said of the post-game scene inside and outside LA's locker room. "We got the coach with the bucket of water.
"We're all on top of the world right now. On top of New England."
Brendan McGovern made the most of his open-net opportunity in the second sudden-death minute of the Martin/Earl tournament. It netted top-seeded Berkshire the large-school championship.
McGovern made St. Sebastian's goaltender Gordon Donnelly pay for an aggressive decision. Donnelly left the crease with an all-out dive to poke-check a rebound toward the right boards. But the puck stayed in the slot, and the forward from Centerport, N.Y., fired a strike.
Fifty-one seconds earlier, Donnelly (38 saves) made a dazzling glove save to keep second-seeded St. Sebastian's in the fight. Charlie Corcoran split two defenders and, with an open look at the net, snapped off a wrister from the low left-wing circle.
Berkshire built a 2-0 lead, courtesy of first- and second-period goals by Gus Harms and Greg Smart. But St. Sebastian's closed the second period sandwiching markers around a tally by Berkshire's Corey Wisnowski.
Those bookend goals, from Tommy Kelley and Danny O'Regan, pulled St. Sebastian's within 3-2.
David Loughborough delivered the equalizer at the 6:59 mark of the third period. He beat Patrick Feeley (27 saves) with a power-play goal.
Nick Roberto ended the Piatelli/Simmons tournament, lifting top-seeded KUA to the small school championship with 1:27 left in overtime.
Casey Miller forced a critical turnover along the boards and sent Roberto up ice, who beat Holderness goaltender Andy Monroe (40 saves) for the championship-clincher.
Both Monroe and KUA netminder Ryan Lund (28 saves) made several timely stops after third-seeded Holderness tied the final at 2-apiece. Gavin Bayreuther recorded the equalizer with a power-play blast from the blue line at the 9:43 mark of the third period.
Early in the third frame, KUA's Niko Rufo charged in from the right-wing side to snap a 1-1 deadlock.
Nick Renzi staked Holderness to its only lead, burying a second-period rebound at the 9:01 mark. The lead lasted less than 4 minutes as Jonathan Charbonneau connected on a breakout chance to knot the score.

Recap: Lawrence Academy 6, Thayer 0
January, 4, 2012
By Brendan Hall | ESPNBoston.com
BOSTON -- Things were going by swimmingly, almost sleepy, through the first 18 minutes of play between Lawrence Academy and Thayer Academy, on the ice at Fenway Park.
Then things went untracked -- and in hurry.
The Spartans (10-1-1) opened up the second period with three goals in a span of 1:24 to blow the game wide open, making life difficult for Thayer goaltenders Robert McGovern and Pat Finn with rush after rush, en route to a 6-0 win in the third game of the day at today's "Frozen Fenway" series.
"That's probably one of the shortest in a while," said senior forward Devin Tringale (two goals, assist) when asked about the last time he'd been a part of such a quick scoring flurry. "I can't remember last time."
Lawrence's "Red Line" of Tringale, George Hunkele and Tyler Whitney combined for seven points to carry much of the scoring, and the chemistry between the three was evident in the second period scoring spree.
"They played great," head coach Kevin Potter said of the line. "They've been playing together all year long, and really it's been a three-line effort, but they got some good goals tonight."
Tringale found the back of the net just 24 seconds in, when he took a beautiful Whitney feed on an odd-man rush, set up right outside McGovern's crease. Bill Messa was next, scoring a minute later at 1:25, and Conor Helfrich made it 3-0 just 25 seconds later with some tic-tac-toe action. Defenseman Jacob Schefter brought the puck through the neutral zone down the left boards before skipping it up to Tom Newton, who tipped it across the slot for an easy glove-side goal.
Lawrence scored twice more in the period, with another Tringale finish in front and a shorthanded goal from Matt Baldino, for the 5-0 advantage.
Thayer fell to 2-8.
Lockdown D triggers breakout
Sparking the Spartans' exceptional play through the neutral zone was some crisp passing from the back end by defensemen like Connor McGuirk and Matt Doherty, triggering breakouts with long darts up the flanks. The defensive pairings won many 50-50 battles along the boards, and gave the Tigers little breathing room between the circles, denying entry passes. Goaltender Nathaniel Heilbron picked up the shutout with 17 saves, but admitted it was made an easy night.
That carried up the ice, where transition play was a key point in scouting heading into this game.
"We've been working on that in practice, getting our feet moving," Tringale said. "So I think that was key going into it, a lot of transition play that we've been working on. It just clicked today, and that's what helped us be effective."
Said Potter, "We knew they were young, we've got a much older team than they are, so we knew they were gonna try to bottle us up. So we just tried to support the puck, and we've got a lot of seniors out there that knew what they were doing, and with a lot of skill. We just practiced breaking the trap, and stuff like that."
PK efficient
The Spartans were also efficient with a man down, killing off all three of the Tigers' power play opportunities with good economy of motion.
"We really worked on that this week, a lot of starting and stopping, all the little things," Potter said. "Again, we have a lot of experience there."
First time for Vancouverite
A repeated theme throughout the "Frozen Fenway" series will be the awed experience of playing an outdoor hockey game at one of the nation's oldest and most beloved ballparks. Players like Tringale soaked in the allure -- "It's a blast," he smiled to reporters -- though the Medford native admits it's not his first experience with outdoor hockey. He first learned the sport as a youth learning to skate on a pond near his house, and noted similarities between the ice texture with that pond's and Fenway's.
But for Heilbron, a native of West Vancouver, tonight's game was his first such endeavor.
"It doesn't get cold enough out there, too close to the ocean," he said. "[This] is surreal, incredible. It's so much fun, just...you can't really say anything about it until you get on the ice -- I've seen the Winter Classic games on TV -- but just being out there is unbelievable."

The girl had several incidents involving police just in thelast couple months but never said anything? When police arrested Trevor why didn't she say anything then or what about when she was arrested at her dads buisness?Her she had her son with her it and they were staying at her dads place of buisness,or the fact that her and Trevor would stay at her dads buisness when they had no where to go.Trevor even worked for her dads buisness he was paid under the table.You wont find record of it but then all his employees have been getting paid under the table for some time that's why the IRS is auditing him.Didn't she tell police they would find several fire arms and a meth lab at the residence but the police didn't find either.There is no deadbolt on the basement door there's a slidebolt on the inside of the door but that keeps people out not in.Then law enforcement couldn't locate her for over 24 hours???????I thought the ring leader Spade!!!!!!! Was still out there shouldn't she be in protective custody not out chasing a bag.There's so much more that doesn't add up. POLICE say that there's so much that coroborates her story I'm here to tell you thats a lie the girl is a liar and when the truth about her lies come out she should get the prison sentence that awaits the ones being falsely accused. What do you think.

VIEWS: 2 PAGES: 12 CATEGORY: Drugs POSTED ON: 9/3/2010
The present invention concerns stable dispersions or compositions of gas filled microvesicles in aqueous carrier liquids. These dispersions are generally usable for most kinds of applications requiring gases homogeneously dispersed in liquids. One notable application for such dispersions is to be injected into living beings, for instance for ultrasonic echography and other medical applications. The invention also concerns the methods for making the foregoing compositions including somematerials involved in the preparations, for instance pressure-resistant gas-filled microbubbles, microcapsules and microballoons.BACKGROUND OF INVENTIONIt is well known that microbodies or microglobules of air or gas (defined here as microvesicles), e.g. microbubbles or microballoons, suspended in a liquid are exceptionally efficient ultrasound reflectors for echography. In this disclosure theterm of "microbubble" specifically designates hollow spheres or globules, filled with air or a gas, in suspension in a liquid which generally result from the introduction therein of air or gas in divided form, the liquid preferably also containingsurfactants or tensides to control the surface properties and the stability of the bubbles. The term of "microcapsule" or "microballoon" designates preferably air or gas-filled bodies with a material boundary or envelope, i.e. a polymer membrane wall. Both microbubbles and microballoons are useful as ultrasonic contrast agents. For instance injecting into the bloodstream of living bodies suspensions of air-filled microbubbles or microballoons (in the range of 0.5 to 10 .mu.m) in a carrier liquid willstrongly reinforce ultrasonic echography Imaging, thus aiding in the visualization of internal organs. Imaging of vessels and internal organs can strongly help in medical diagnosis, for instance for the detection of cardiovascular and other diseases.The formation of suspensions of microbubbles in an injectable liquid carrier suitable for echography can b

Description TECHNICAL FIELD The present invention concerns stable dispersions or compositions of gas filled microvesicles in aqueous carrier liquids. These dispersions are generally usable for most kinds of applications requiring gases homogeneously dispersed in liquids. One notable application for such dispersions is to be injected into living beings, for instance for ultrasonic echography and other medical applications. The invention also concerns the methods for making the foregoing compositions including some materials involved in the preparations, for instance pressure-resistant gas-filled microbubbles, microcapsules and microballoons. BACKGROUND OF INVENTION It is well known that microbodies or microglobules of air or gas (defined here as microvesicles), e.g. microbubbles or microballoons, suspended in a liquid are exceptionally efficient ultrasound reflectors for echography. In this disclosure the term of "microbubble" specifically designates hollow spheres or globules, filled with air or a gas, in suspension in a liquid which generally result from the introduction therein of air or gas in divided form, the liquid preferably also containing surfactants or tensides to control the surface properties and the stability of the bubbles. The term of "microcapsule" or "microballoon" designates preferably air or gas-filled bodies with a material boundary or envelope, i.e. a polymer membrane wall. Both microbubbles and microballoons are useful as ultrasonic contrast agents. For instance injecting into the bloodstream of living bodies suspensions of air-filled microbubbles or microballoons (in the range of 0.5 to 10 .mu.m) in a carrier liquid will strongly reinforce ultrasonic echography Imaging, thus aiding in the visualization of internal organs. Imaging of vessels and internal organs can strongly help in medical diagnosis, for instance for the detection of cardiovascular and other diseases. The formation of suspensions of microbubbles in an injectable liquid carrier suitable for echography can be produced by the release of a gas dissolved under pressure in this liquid, or by a chemical reaction generating gaseous products, or by admixing with the liquid soluble or insoluble solids containing air or gas trapped or adsorbed therein. For instance, in U.S. pat. No. 4,446,442 (Schering), there are disclosed a series of different techniques for producing suspensions of gas microbubbles in a sterilized injectable liquid carrier using (a) a solution of a tenside (surfactant) in a carrier liquid (aqueous) and (b) a solution of a viscosity enhancer as stabilizer. For generating the bubbles, the techniques disclosed there include forcing at high velocity a mixture of (a), (b) and air through a small aperture; or injecting (a) into (b) shortly before use together with a physiologically acceptable gas; or adding an acid to (a) and a carbonate to (b), both components being mixed together just before use and the acid reacting with the carbonate to generate CO.sub.2 bubbles; or adding an over-pressurized gas to a mixture of (a) and (b) under storage, said gas being released into microbubbles at the time when the mixture is used for injection. EP-A-131,540 (Schering) discloses the preparation of microbubble suspensions in which a stabilized injectable carrier liquid, e.g. a physiological aqueous solution of salt, or a solution of a sugar like maltose, dextrose, lactose or galactose, is mixed with solid microparticles (in the 0.1 to 1 .mu.m range) of the same sugars containing entrapped air. In order to develop the suspension of bubbles in the liquid carrier, both liquid and solid components are agitated together under sterile conditions for a few seconds and, once made, the suspension must then be used immediately, i.e. it should be injected within 5-10 minutes for echographic measurements; indeed, because they are evanescent, the bubble concentration becomes too low for being practical after that period. In an attempt to cure the evanescence problem, microballoons, i.e. microvesicles with a material wall, have been developed. As said before, while the microbubbles only have an immaterial or evanescent envelope, i.e. they are only surrounded by a wall of liquid whose surface tension is being modified by the presence of a surfactant, the microballoons or microcapsules have a tangible envelope made of substantive material, e.g. a polymeric membrane with definite mechanical strength. In other terms, they are microvesicles of material in which the air or gas is more or less tightly encapsulated. For instance, U.S. Pat. No. 4,276,885 (Tickner et al.) discloses using surface membrane microcapsules containing a gas for enhancing ultrasonic images, the membrane including a multiplicity of non-toxic and non-antigenic organic molecules. In a disclosed embodiment, these microbubbles have a gelatine membrane which resists coalescence and their preferred size is 5-10 .mu.m. The membrane of these microbubbles is said to be sufficiently stable for making echographic measurements. Air-filled microballoons without gelatin are disclosed in U.S. Pat. No. 4,718,433 (Feinstein). These microvesicles are made by sonication (5 to 30 kHz) of protein solutions like 5% serum albumin and have diameters in the 2-20 .mu.m range, mainly 2-4 .mu.m. The microvesicles are stabilized by denaturation of the membrane forming protein after sonication, for instance by using heat or by chemical means, e.g. by reaction with formaldehyde or glutaraldehyde. The concentration of stable microvesicles obtained by this technique is said to be about 8.times.10.sup.6 /ml in the 2-4 .mu.m range, about 10.sup.6 /ml in the 4-5 .mu.m range and less than 5.times.10.sup.5 in the 5-6 .mu.m range. The stability time of these microvesicles is said to be 48 hrs or longer and they permit convenient left heart imaging after intravenous injection. For instance, the sonicated albumin microbubbles when injected into a peripheral vein are capable of transpulmonary passage. This results in echocardiographic opacification of the left ventricle cavity as well as myocardial tissues. Recently, still further improved microballoons for injection ultrasonic echography have been reported in EP-A-324.938 (Widder). In this document there are disclosed high concentrations (more than 10.sup.8 /ml) of air-filled protein-bounded microvesicles of less than 10 .mu.m which have life-times of several months or more. Aqueous suspensions of these microballoons are produced by ultrasonic cavitation of solutions of heat denaturable proteins, e.g. human serum albumin, which operation also leads to a degree of foaming of the membrane-forming protein and its subsequent hardening by heat. Other proteins such as hemoglobin and collagen were also said to be convenient in this process. The high storage stability of the suspensions of microballoons disclosed in EP-A-324.938 enables them to be marketed as such, i.e. with the liquid carrier phase, which is a strong commercial asset since preparation before use is no longer necessary. Similar advantages have been recently discovered in connection with the preparation of aqueous microbubble suspensions, i.e. there has been discovered storage-stable dry pulverulent composition which will generate long-lasting bubble suspensions upon the addition of water. This is being disclosed in Application PCT/EP 91/00620 where liposomes comprising membrane-forming lipids are freeze-dried, and the freeze-dried lipids, after exposure to air or a gas for a period of time, will produce long-lasting bubble suspensions upon simple addition thereto of an aqueous liquid carrier. Despite the many progresses achieved regarding the stability under storage of aqueous microbubble suspensions, this being either in the precursor or final preparation stage, there still remained until now the problem of vesicle durability when the suspensions are exposed to overpressure, e.g. pressure variations such as that occurring after injection in the blood stream of a patient and consecutive to heart pulses, particularly in the left ventricle. Actually, the present inventors have observed that, for instance in anaesthetised rabbits, the pressure variations are not sufficient to substantially alter the bubble count for a period of time after injection. In contrast, in dogs and human patients, typical microbubbles or microballoons filled with common gases such as air, methane or CO.sub.2 will collapse completely in a matter of seconds after injection due to the blood pressure effect. This observation has been confirmed by others: For instance. S. GOTTLIEB et al. in J. Am. Soc. of Echocardiography 3 (1990) 238 have reported that cross-linked albumin microballoons prepared by the sonication method were losing all echogenic properties after being subjected to an overpressure of 60 Torr. It became hence important to solve the problem and to increase the useful life of suspensions of microbubbles and membrane bounded microballoons under pressure in order to ensure that echographic measurements can be performed in vivo safely and reproducibly. It should be mentioned at this stage that another category of echogenic image enhancing agents has been proposed which resist overpressures as they consist of plain microspheres with a porous structure, such porosity containing air or a gas. Such microspheres are disclosed for instance in WO-A-91/12823 (DELTA BIOTECHNOLOGY), EP-A-327 490 (SCHERING) and EP-A-458 079 (HOECHST). The drawback with the plain porous microspheres is that the encapsulated gas-filled free space is generally too small for good echogenic response and the spheres lack adequate elasticity. Hence the preference generally remains with the hollow microvesicles and a solution to the collapsing problem was searched. DISCLOSURE OF THE INVENTION This problem has now been solved by using gases or gas mixtures in conformity with the criteria outlined in the claims. Briefly, it has been found that when the echogenic microvesicles are made in the presence of a gas, respectively are filled at least in part with a gas, having physical properties in conformity with the equation below, then the microvesicles remarkably resist pressure >60 Torr after injection for a time sufficient to obtain reproducible echographic measurements: ##EQU1## In the foregoing equation, "s" designates the solubilities in water expressed as the "BUNSEN" coefficients, i.e. as volume of gas dissolved by unit volume of water under standard conditions (1 bar, 25.degree. C.), and under partial pressure of the given gas of 1 atm (see the Gas Encyclopaedia, Elsevier 1976). Since, under such conditions and definitions, the solubility of air is 0.0167, and the square root of its average molecular weight (Mw) is 5.39, the above relation simplifies to: In the Examples to be found hereafter there is disclosed the testing of echogenic microbubbles and microballoons (see the Tables) filled with a number of different gases and mixtures thereof, and the corresponding resistance thereof to pressure increases, both in vivo and in vitro. In the Tables, the water solubility factors have also been taken from the aforecited Gas Encyclopaedia from "L'Air Liquide", Elsevier Publisher (1976). The microvesicles in aqueous suspension containing gases according to the invention include most microbubbles and microballoons disclosed until now for use as contrast agents for echography. The preferred microballoons are those disclosed in EP-A-324.938, PCT/EP91/01706 and EP-A-458 745; the preferred microbubbles are those of PCT/EP91/00620; these microbubbles are advantageously formed from an aqueous liquid and a dry powder (microvesicle precursors) containing lamellarized freeze-dried phospholipids and stabilizers; the microbubbles are developed by agitation of this powder in admixture with the aqueous liquid carrier. The microballoons of EP-A-458 745 have a resilient interfacially precipitated polymer membrane of controlled porosity. They are generally obtained from emulsions into microdroplets of polymer solutions in aqueous liquids, the polymer being subsequently caused to precipitate from its solution to form a filmogenic membrane at the droplet/liquid interface, which process leads to the initial formation of liquid-filled microvesicles, the liquid core thereof being eventually substituted by a gas. In order to carry out the method of the present invention, i.e. to form or fill the microvesicles, whose suspensions in aqueous carriers constitute the desired echogenic additives, with the gases according to the foregoing relation, one can either use, as a first embodiment, a two step route consisting of (1) making the microvesicles from appropriate starting materials by any suitable conventional technique in the presence of any suitable gas, and (2) replacing this gas originally used (first gas) for preparing the microvesicles with a new gas (second gas) according to the invention (gas exchange technique). Otherwise, according to a second embodiment, one can directly prepare the desired suspensions by suitable usual methods under an atmosphere of the new gas according to the invention. If one uses the two-step route, the initial gas can be first removed from the vesicles (for instance by evacuation under suction) and thereafter replaced by bringing the second gas into contact with the evacuated product, or alternatively, the vesicles still containing the first gas can be contacted with the second gas under conditions where the second gas will displace the first gas from the vesicles (gas substitution). For instance, the vesicle suspensions, or preferably precursors thereof (precursors here may mean the materials the microvesicle envelopes are made of, or the materials which, upon agitation with an aqueous carrier liquid, will generate or develop the formation of microbubbles in this liquid), can be exposed to reduced pressure to evacuate the gas to be removed and then the ambient pressure is restored with the desired gas for substitution. This step can be repeated once or more times to ensure complete replacement of the original gas by the new one. This embodiment applies particularly well to precursor preparations stored dry, e.g. dry powders which will regenerate or develop the bubbles of the echogenic additive upon admixing with an amount of carrier liquid. Hence, in one preferred case where microbubbles are to be formed from an aqueous phase and dry laminarized phospholipids, e.g. powders of dehydrated lyophilized liposomes plus stabilizers, which powders are to be subsequently dispersed under agitation in a liquid aqueous carrier phase, it is advantageous to store this dry powder under an atmosphere of a gas selected according to the invention. A preparation of such kind will keep indefinitely in this state and can be used at any time for diagnosis, provided it is dispersed into sterile water before injection. Otherwise, and this is particularly so when the gas exchange is applied to a suspension of microvesicles in a liquid carrier phase, the latter is flushed with the second gas until the replacement (partial or complete) is sufficient for the desired purpose. Flushing can be effected by bubbling from a gas pipe or, in some cases, by simply sweeping the surface of the liquid containing the vesicles under gentle agitation with a stream (continuous or discontinuous) of the new gas. In this case, the replacement gas can be added only once in the flask containing the suspension and allowed to stand as such for a while, or it can be renewed one or more times in order to assure that the degree of renewal (gas exchange) is more or less complete. Alternatively, in a second embodiment as said before, one will effect the full preparation of the suspension of the echogenic additives starting with the usual precursors thereof (starting materials), as recited in the prior art and operating according to usual means of said prior art, but in the presence of the desired gases or mixture of gases according to the invention instead of that of the prior art which usually recites gases such as air, nitrogen, CO.sub.2 and the like. It should be noted that in general the preparation mode involving one first type of gas for preparing the microvesicles and, thereafter, substituting the original gas by a second kind of gas, the latter being intended to confer different echogenic properties to said microvesicles, has the following advantage: As will be best seen from the results in the Examples hereinafter, the nature of the gas used for making the microvesicles, particularly the microballoons with a polymer envelope, has a definitive influence on the overall size (i.e. the average mean diameter) of said microvesicles; for instance, the size of microballoons prepared under air with precisely set conditions can be accurately controlled to fall within a desired range, e.g. the 1 to 10 .mu.m range suitable for echographying the left and right heart ventricles. This not so easy with other gases, particularly the gases in conformity with the requirements of the present invention; hence, when one wishes to obtain microvesicles in a given size range but filled with gases the nature of which would render the direct preparation impossible or very hard, one will much advantageously rely on the two-steps preparation route, i.e. one will first prepare the microvesicles with a gas allowing more accurate diameter and count control, and thereafter replace the first gas by a second gas by gas exchange. In the description of the Experimental part that follows (Examples), gas-filled microvesicles suspended in water or other aqueous solutions have been subjected to pressures over that of ambient. It was noted that when the overpressure reached a certain value (which is generally typical for a set of microsphere parameters and working conditions like temperature, compression rate, nature of carrier liquid and its content of dissolved gas (the relative importance of this parameter will be detailed hereinafter), nature of gas filler, type of echogenic material, etc.), the microvesicles started to collapse, the bubble count progressively decreasing with further increasing the pressure until a complete disappearance of the sound reflector effect occurred. This phenomenon was better followed optically, (nephelometric measurements) since it is paralleled by a corresponding change in optical density, i.e. the transparency of the medium increases as the bubble progressively collapse. For this, the aqueous suspension of microvesicles (or an appropriate dilution thereof was placed in a spectrophotometric cell maintained at 25.degree. C. (standard conditions) and the absorbance was measured continuously at 600 or 700 nm, while a positive hydrostatic overpressure was applied and gradually increased. The pressure was generated by means of a peristaltic pump (GILSON's Mini-puls) feeding a variable height liquid column connected to the spectrophotometric cell, the latter being sealed leak-proof. The pressure was measured with a mercury manometer calibrated in Torr. The compression rate with time was found to be linearly correlated with the pump's speed (rpm's). The absorbance in the foregoing range was found to be proportional to the microvesicle concentration in the carrier liquid. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a graph which relates the bubble concentration (bubble count), expressed in terms of optical density in the aforementioned range, and the pressure applied over the bubble suspension. The data for preparing the graph are taken from the experiments reported in Example 4. FIG. 1 shows graphically that the change of absorbance versus pressure is represented by a sigmoid-shaped curve. Up to a certain pressure value, the curve is nearly flat which indicates that the bubbles are stable. Then, a relatively fast absorbance drop occurs, which indicates the existence of a relatively narrow critical region within which any pressure increase has a rather dramatic effect on the bubble count. When all the microvesicles have disappeared, the curve levels off again. A critical point on this curve was selected in the middle between the higher and lower optical readings, i.e. intermediate between the "full"-bubble (OD max) and the "no"-bubble (OD min) measurements, this actually corresponding where about 50% of the bubbles initially present have disappeared, i.e. where the optical density reading is about half the initial reading, this being set, in the graph, relative to the height at which the transparency of the pressurized suspension is maximal (base line). This point which is also in the vicinity where the slope of the curve is maximal is defined as the critical pressure PC. It was found that for a given gas, PC does not only depend on the aforementioned parameters but also, and particularly so, on the actual concentration of gas (or gases) already dissolved in the carrier liquid: the higher the gas concentration, the higher the critical pressure. In this connection, one can therefore increase the resistance to collapse under pressure of the microvesicles by making the carrier phase saturated with a soluble gas, the latter being the same, or not, (i.e. a different gas) as the one that fills the vesicles. As an example, air-filled microvesicles could be made very resistant to overpressures (>120 Torr) by using, as a carrier liquid, a saturated solution of CO.sub.2. Unfortunately, this finding is of limited value in the diagnostic field since once the contrast agent is injected to the bloodstream of patients (the gas content of which is of course outside control), it becomes diluted therein to such an extent that the effect of the gas originally dissolved in the injected sample becomes negligible. Another readily accessible parameter to reproducibly compare the performance of various gases as microsphere fillers is the width of the pressure interval (.DELTA.P) limited by the pressure values under which the bubble counts (as expressed by the optical densities) is equal to the 75% and 25% of the original bubble count. Now, it has been surprisingly found that for gases where the pressure difference DP=P.sub.25 -P.sub.75 exceeds a value of about 25-30 Torr, the killing effect of the blood pressure on the gas-filled microvesicles is minimized, i.e. the actual decrease in the bubble count is sufficiently slow not to impair the significance, accuracy and reproducibility of echographic measurements. It was found, in addition, that the values of PC and .DELTA.P also depend on the rate of rising the pressure in the test experiments illustrated by FIG. 1, i.e. in a certain interval of pressure increase rates (e.g. in the range of several tens to several hundreds of Torr/min), the higher the rate, the larger the values for PC and .DELTA.P. For this reason, the comparisons effected under standard temperature conditions were also carried out at the constant increase rate of 100 Torr/min. It should however be noted that this effect of the pressure increase rate on the measure of the PC and .DELTA.P values levels off for very high rates; for instance the values measured under rates of several hundreds of Torr/min are not significantly different from those measured under conditions ruled by heart beats. Although the very reasons why certain gases obey the aforementioned properties, while others do not, have not been entirely clarified, it would appear that some relation possibly exists in which, in addition to molecular weight and water solubility, dissolution kinetics, and perhaps other parameters, are involved. However these parameters need not be known to practise the present invention since gas eligibility can be easily determined according to the aforediscussed criteria. The gaseous species which particularly suit the invention are, for instance, halogenated hydrocarbons like the freons and stable fluorinated chalcogenides like SF.sub.6, SeF.sub.6 and the like. It has been mentioned above that the degree of gas saturation of the liquid used as carrier for the microvesicles according to the invention has an importance on the vesicle stability under pressure variations. Indeed, when the carrier liquid in which the microvesicles are dispersed for making the echogenic suspensions of the invention is saturated at equilibrium with a gas, preferably the same gas with which the microvesicles are filled, the resistance of the microvesicles to collapse under variations of pressure is markedly increased. Thus, when the product to be used as a contrast agent is sold dry to be mixed just before use with the carrier liquid (see for instance the products disclosed in PCT/EP91/00620 mentioned hereinbefore), it is quite advantageous to use, for the dispersion, a gas saturated aqueous carrier. Alternatively, when marketing ready-to-use microvesicle suspensions as contrast agents for echography, one will advantageously use as the carrier liquid for the preparation a gas saturated aqueous solution; in this case the storage life of the suspension will be considerably increased and the product may be kept substantially unchanged (no substantial bubble count variation) for extended periods, for instance several weeks to several months, and even over a year in special cases. Saturation of the liquid with a gas may be effected most easily by simply bubbling the gas into the liquid for a period of time at room temperature. EXAMPLE 1 Albumin microvesicles filled with air or various gases were prepared as described in EP-A-324 938 using a 10 ml calibrated syringe filled with a 5% human serum albumin (HSA) obtained from the Blood Transfusion Service, Red-Cross Organization, Bern, Switzerland. A sonicator probe (Sonifier Model 250 from Branson Ultrasonic Corp, USA) was lowered into the solution down to the 4 ml mark of the syringe and sonication was effected for 25 sec (energy setting=8). Then the sonicator probe was raised above the solution level up to the 6 ml mark and sonication was resumed under the pulse mode (cycle=0.3) for 40 sec. After standing overnight at 4.degree. C., a top layer containing most of the microvesicles had formed by buoyancy and the bottom layer containing unused albumin debris of denatured protein and other insolubles was discarded. After resuspending the microvesicles in fresh albumin solution the mixture was allowed to settle again at room temperature and the upper layer was finally collected. When the foregoing sequences were carried out under the ambient atmosphere, air filled microballoons were obtained. For obtaining microballoons filled with other gases, the albumin solution was first purged with a new gas, then the foregoing operational sequences were effected under a stream of this gas flowing on the surface of the solution; then at the end of the operations, the suspension was placed in a glass bottle which was extensively purged with the desired gas before sealing. The various suspensions of microballoons filled with different gases were diluted to 1:10 with distilled water saturated at equilibrium with air, then they were placed in an optical cell as described above and the absorbance was recorded while increasing steadily the pressure over the suspension. During the measurements, the suspensions temperature was kept at 25.degree. C. The results are shown in the Table 1 below and are expressed in terms of the critical pressure PC values registered for a series of gases defined by names or formulae, the characteristic parameters of such gases, i.e. Mw and water solubility being given, as well as the original bubble count and bubble average size (mean diameter in volume). TABLE 1 Bubble Bubble Solu- count size Sgas/ Sample Gas Mw bility (10.sup.8 /ml) (.mu.m) PC(Torr) Mw AFre1 CF.sub.4 88 .0038 0.8 5.1 120 .0004 AFre2 CBrF.sub.3 149 .0045 0.1 11.1 104 .0004 ASF1 SF.sub.6 146 .005 13.9 6.2 150 .0004 ASF2 SF.sub.6 146 .005 2.0 7.9 140 .0004 AN1 N.sub.2 28 .0144 0.4 7.8 62 .0027 A14 Air 29 .0167 3.1 11.9 53 .0031 A18 Air 29 .0167 3.8 9.2 52 -- A19 Air 29 .0167 1.9 9.5 51 -- AMe1 CH.sub.4 16 .032 0.25 8.2 34 .008 AKr1 Kr 84 .059 0.02 9.2 86 .006 AX1 Xe 131 .108 0.06 17.2 65 .009 AX2 Xe 131 .108 0.03 16.5 89 .009 From the results of Table 1, it is seen that the critical pressure PC increases for gases of lower solubility and higher molecular weight. It can therefore be expected that microvesicles filled with such gases will provide more durable echogenic signals in vivo. It can also be seen that average bubble size generally increases with gas solubility. EXAMPLE 2 Aliquots (1 ml) of some of the microballoon suspensions prepared in Example 1 were injected in the jugular vein of experimental rabbits in order to test echogenicity in vivo. Imaging of the left and right heart ventricles was carried out in the grey scale mode using an Acuson 128-XP5 echography apparatus and a 7.5 MHz transducer. The duration of contrast enhancement in the left ventricle was determined by recording the signal for a period of time. The results are gathered in Table 2 below which also shows the PC of the gases used. TABLE 2 Duration of Sample (Gas) contrast (sec) PC (Torr) AMe1 (CH.sub.4) zero 34 A14 (air) 10 53 A18 (air) 11 52 AX1 (Xe) 20 65 AX2 (Xe) 30 89 ASF2 (SF.sub.6) >60 140 From the above results, one can see the existence of a definite correlation between the critical pressure of the gases tried and the persistence in time of the echogenic signal. EXAMPLE 3 A suspension of echogenic air-filled galactose microparticles (Echovist.RTM. from SCHERING AG) was obtained by shaking for 5 sec 3 g of the solid microparticles in 8.5 ml of a 20% galactose solution. In other preparations, the air above a portion of Echovist.RTM. particles was evacuated (0.2 Torr) and replaced by an SF.sub.6 atmosphere, whereby, after addition of the 20% galactose solution, a suspension of microparticles containing associated sulfur hexafluoride was obtained. Aliquots (1 ml) of the suspensions were administered to experimental rabbits (by injection in the jugular vein) and imaging of the heart was effected as described in the previous example. In this case the echogenic microparticles do not transit through the lung capillaries, hence imaging is restricted to the right ventricle and the overall signal persistence has no particular significance. The results of Table 3 below show the value of signal peak intensity a few seconds after injection. TABLE 3 Signal peak Sample No Gas (arbitrary units) Gal1 air 114 Gal2 air 108 Gal3 SF.sub.6 131 Gal4 SF.sub.6 140 It can be seen that sulfur hexafluoride, an inert gas with low water solubility, provides echogenic suspensions which generate echogenic signals stronger than comparable suspensions filled with air. These results are particularly interesting in view of the teachings of EP-A-441 468 and 357 163 (SCHERING) which disclose the use for echography purposes of micropartcles, respectively, cavitate and clathrate compounds filled with various gases including SF6; these documents do not however report particular advantages of SF6 over other more common gases with regard to the echogenic response. EXAMPLE 4 A series of echogenic suspensions of gas-filled microbubbles were prepared by the general method set forth below: One gram of a mixture of hydrogenated soya lecithin (from Nattermann Phospholipids GmbH, Germany) and dicetyl-phosphate (DCP), in 9/1 molar ratio, was dissolved in 50 ml of chloroform, and the solution was placed in a 100 ml round flask and evaporated to dryness on a Rotavapor apparatus. Then, 20 ml of distilled water were added and the mixture was slowly agitated at 75.degree. C. for an hour. This resulted in the formation of a suspension of multilamellar liposomes (MLV) which was thereafter extruded at 75.degree. C. through, successively, 3 .mu.m and 0.8 .mu.m polycarbonate membranes (Nuclepore.RTM.). After cooling, 1 ml aliquots of the extruded suspension were diluted with 9 ml of a concentrated lactose solution (83 g/l), and the diluted suspensions were frozen at -45.degree. C. The frozen samples were thereafter freeze-dried under high vacuum to a free-flowing powder in a vessel which was ultimately filled with air or a gas taken from a selection of gases as indicated in Table 4 below. The powdery samples were then resuspended in 10 ml of water as the carrier liquid, this being effected under a stream of the same gas used to fill the said vessels. Suspension was effected by vigorously shaking for 1 min on a vortex mixer. The various suspensions were diluted 1:20 with distilled water equilibrated beforehand with air at 25.degree. C. and the dilutions were then pressure tested at 25.degree. C. as disclosed in Example 1 by measuring the optical density in a spectrophotometric cell which was subjected to a progressively increasing hydrostatic pressure until all bubbles had collapsed. The results are collected in Table 4 below which, in addition to the critical pressure PC, gives also the .DELTA.P values (see FIG. 1).

The behavior of the microbubbles is therefore similar to that of the microballoons in this regard. Also, the less water-soluble gases with the higher molecular weights provide the flattest bubble-collapse/pressure curves (i.e. .DELTA.P is the widest) which is also an important factor of echogenic response durability in vivo, as indicated hereinbefore. EXAMPLE 5 Some of the microbubble suspensions of Example 4 were injected to the jugular vein of experimental rabbits as indicated in Example 2 and imaging of the left heart ventricle was effected as indicated previously. The duration of the period for which a useful echogenic signal was detected was recorded and the results are shown in Table 5 below in which C.sub.4 F.sub.8 indicates octafluorocyclobutane.

EXAMPLE 6 Suspensions of microbubbles were prepared using different gases exactly as described in Example 4, but replacing the lecithin phospholipid ingredient by a mole equivalent of diarachidoyl-phosphatidylcholine (C.sub.20 fatty acid residue) available from Avanti Polar Lipids, Birmingham. Ala., USA. The phospholipid to DCP molar ratio was still 9/1. Then the suspensions were pressure tested as in Example 4; the results, collected in Table 6A below, are to be compared with those of Table 4.

This was further confirmed by repeating the foregoing experiments but replacing the phospholipid component by its higher homolog, i.e. di-behenoyl-phosphatidylcholine (C.sub.22 fatty acid residue). In this case, the resistance to collapse with pressure of the microbubbles suspensions was still further increased. Some of the microbubbles suspensions of this Example were tested in dogs as described previously for rabbits (imaging of the heart ventricles after injection of 5 ml samples in the anterior cephalic vein). A significant enhancement of the useful in-vivo echogenic response was noted, in comparison with the behavior of the preparations disclosed in Example 4, i.e. the increase in chain length of the fatty-acid residue in the phospholipid component increases the useful life of the echogenic agent in-vivo. In the next Table below, there is shown the relative stability in the left ventricle of the rabbit of microbubbles (SF.sub.6) prepared from suspensions of a series of phospholipids whose fatty acid residues have different chain lengths (<injected dose: 1 ml/rabbit).

This is justified by the results given below which show the variations of the PC values for different gases in function to the rate of pressure increase. In these samples DMPC was the phospholipid used.

Then the air in some of the samples was replaced by other gases by the gas-exchange sweep method at ambient pressure. Then, after diluting to 1:10 with distilled water as usual, the samples were subjected to pressure testing as in Example 1. From the results gathered in Table 7 below, it can be seen that the two-steps preparation mode gives, in some cases, echo-generating agents with better resistance to pressure than the one-step preparation mode of Example 1.

Three grams of Pluronic.RTM. F68 (a copolymer of polyoxyethylene-polyoxypropylene with a molecular weight of 8400), 1g of dipalmitoylphosphatidylglycerol (Na salt, AVANTI Polar Lipids) and 3.6 g of glycerol were added to 80 ml of distilled water. After heating at about 80.degree. C., a clear homogenous solution was obtained. The tenside solution was cooled to room temperature and the volume was adjusted to 100 ml. In some experiments (see Table 8) dipalmitoylphosphatidyl-glycerol was replaced by a mixture of diarachidoylphosphatidylcholine (920 mg) and 80 mg of dipalmitoylphosphatidic acid (Na salt, AVANTI Polar lipids). The bubble suspensions were obtained by using two syringes connected via a three-way valve. One of the syringes was filled with 5 ml of the tenside solution while the other-was filled with 0.5 ml of air or gas. The three-way valve was filled with the tenside solution before it was connected to the gas-containing syringe. By alternatively operating the two pistons, the tenside solutions were transferred back and forth between the two syringes (5 times in each direction), milky suspensions were formed. After dilution (1:10 to 1:50) with distilled water saturated at equilibrium with air, the resistance to pressure of the preparations was determined according to Example 1. The pressure increase rate was 240 Torr/min. The following results were obtained: TABLE 8 Phospholipid Gas Pc (mm Hg) DP (mm Hg) DPPG air 28 17 DPPG SF.sub.6 138 134 DAPC/DPPA 9/1 air 46 30 DAPC/DPPA 9/1 SF.sub.6 269 253 It follows that by using the method of the invention and replacing air with other gases e.g. SF.sub.6 even with known preparations a considerable improvements i.e. increase in the resistance to pressure may be achieved. This is true both in the case of negatively charged phospholipids (e.g. DPPG) and in the case of mixtures of neutral and negatively charged phospholipids (DAPC/DPPA). The above experiment further demonstrates that the recognised problem sensitivity of microbubbles and microballoons to collapse when exposed to pressure i.e. when suspensions are injected into living beings, has advantageously been solved by the method of the invention. Suspensions with microbubbles or microballoons with greater resistance against collapse and greater stability can advantageously be produced providing suspensions with better reproducibility and improved safety of echographic measurements performed in vivo on a human or animal body. * * * * *

Frantix at Wax Trax
Punk rock hit the musical world like a bomb in the mid-'70s, and the reverberations of that artistic eruption were felt even in places like Aurora, Colorado. In 1978, Aurora was an incredibly boring town, so it comes as no surprise that a few pioneering young men put together a band that embodied the sound and the attitude of punk. Until their dissolution in 1983, the Frantix released only a handful of records and a cassette, but that output, as well as live shows that lived up to the act's name, proved incredibly influential. Matt Bischoff and Rick Kulwicki went on to greater notoriety as members of the Fluid, but everyone who hears "My Dad's a Fuckin' Alcoholic" is struck by its wild energy and profane wit. The reunion show this Saturday, September 20, at Wax Trax is one you shouldn't miss.

You huffyou puffyou sweatand you groan for what seems like an eternity. You step on that scale the next morning to see that it only made a .2 difference in our weight. You throw your head back in frustration thinkinghow? I worked out for a full hour yesterday! Discouraged by your little resultsbefore you know ityou've decided to bag the whole idea of losing those last 5 pounds and head to your freezer for some ice cream. While making the choice to get more healthy and lose some unwanted weightpeople tend to forget that an important key to weight loss and having more knowledge about it in the first place. For instancewhen a woman sets out to lose 5-10 poundsher usual first goal is to start eating better. As she begins to eat bettershe will find that that the first few pounds drop off rather quickly. Delighted by her resultsshe decides to keep what she's doing. If it ain't brokedon't fix itright? Problem isour bodies are amazing at adapting. After a week or 2the woman will begin to notice a decrease in her weight loss. She may even hit a plateau. Which means that even though she is still eating healthyshe will lose little to no weight. That is when people then decide to add in exercise. Depending on your activity level to begin withyou might only exercise by walkingand then gradually work up to jogging. One of the biggest ways to increase weight loss is cardio exercise. Cardio is short for cardiovascularwhich refers to the heart. Cardiovascular exerciseis an exercise that raises your heart rate and keeps it elevated for a period of time. Another name for it is aerobic exercise. The kinds of exercise that are associated with cardiovascular workouts are things like joggingfast walkingswimmingand biking where there is no break in the routine. Soback to the lady whose trying to lose weight. As she sees that her weight loss has plateauedshe will then more than likely introduce exercise into the mix. She might begin walking for 30 minutesor even trying to jog 15 minutes out of the 30. By introducing cardio workouts into her weight loss planshe will then begin to see a difference on her scale. But like stated aboveour bodies do not like to changeand will quickly try to adapt itself to the new exercise. Like the womanor you perhapsare frustrated that once againyou worked out for a full hour and saw little results. But how do we really know how many calories each exercise is allowing us to burn? While we pour our heart and soul into a workoutwe often feel that we should deservingly burn 1,000 calories! After allyou just worked like a mad woman. But what if it's way less than you think? Could that be why your scale is moving so slowly? Like many AmericansI'm sure there are many times after a hard workout you ask yourselfhow many calories did I just burn? Welllet's find the answer.
Although countless websites offer calories burned calculatorsthey are not always accurate. If a site only asks you to type in your weight and how many minutes you did a particular activitymore than likely it's not correct. An older woman and I may be the same weight and do the same exact exercise for precisely one hourhoweverbecause of our age differenceI am more likely to burn more calories because my heart rate can handle going higherand thus burning more. Upon getting myself a heart rate monitor several weeks ago(read my reviews page for details)I was excited to see that it gave an estimation of calories burned. I trust this to be pretty accurate because my monitor requires my agegenderheightand weight. While being able to consistently monitor my heart rate for an entire workoutI believe it is safe to say that my calories burned is accurategive or take a few. So back to the burning (sorry I just had to say that) question: How many calories did I just burn? I decided to perform a series of workout tests. I did 6 of the top cardiovascular workouts for 1 hour and recorded down my calories burned based on my heart rate monitor. Here are the results:
This was actually a fun test to do because I have always wanted to see which exercise burns the most calories. While 3 of them are all in the 400'srunning is the dominate winner. Keep in mind that these results are for my particular ageweightheightetc. Howeveras in any caseif someone else were to perform this testtheir numbers for each specific exercise might be different from minebut the ranking of most calories burned to the least would be about the same. I realize that not everyone can go out and purchase a heart rate monitorso here are a list of calories burned calculator sites that I believe are close to accurate:
*Although the above site only asks for weightit's results have been close to that of my heart rate monitor.
http://www.nutritiondata.com/tools/calories-burned <—–this one is great!
So if you've been frustrated by your small results from your exercisetry figuring out what type of exercise can get you the maximum calories burned. Just remember to not over do itand listen to your body. While losing a few pounds might be beneficial to your overall healthnever go beyond what is best for younot someone else. God wants us to take care of our bodies so we can continue in our service for him. So how many calories did you just burn? Go find the answer!

Publisher's Description
A star athlete at his high school, Bobby Franklin faces graduation with anything but certainty. Should he choose ministry over his beloved baseball? Should he earn a college degree-or skip school and try to make it in baseball-or marry his girlfriend, Ashley? As a Christian, he wonders how he can know specifically what God wants him to do.
Do you know any students like Bobby who have major decisions to make and would like to know God's will? Do you know what to tell them? Do you know how to help? During their search for God's will in their lives, there is one thing for sure they could use: a "911 friend"-a friend who "...is always loyal and a brother [and sister who] is born to help in time of need" (Prov. 17:17)
Through the aid of a gripping true-to-life story, Josh McDowell, along with Ed Stewart, offers biblical insights and practical instruction on how to find God's specific will in one's life. But more importantly, you will learn how to become a true source of encouragement and guidance to someone wanting to know God's will. This book is designed for you to read first and then give to your friend
And if you are that person facing some major issues in life, you will discover key scriptural principles to making tough personal decisions. But more than that, you will find that God really does care about the details of your life and wants what's best for you, and so does your friend-most likely the person who gave you this book.

My oddball grafts.
fatal_fataliiApril 14, 2010
I have taken a Golden Jubilee and grafted it onto a 'Big Beef' rootstock so I hopefully can get the VFFNAT resistance it clamis.
Now here is the oddball part...
I have a bell pepper that I decided to graft to the leftover rootstock of the jubilee tomato. It does not look wilted or dead; but I guess you can say the my main concern is the plant going to live; and since its in the Solanaceae/Nightshade family will I have poison bell peppers ???
.... I also wish to graft a eggplant and hot pepper together [or speretatly] onto a resistant mater rootstock. Any thoughts?

When watching a sports game, would you bet on who's going to lose?
That's essentially what "short-sellers" do: they bet that a stock, sector or broader benchmark will fall in price. ("Long investors" bet that prices will rise.)
Here's a simplified example of how shorting works:
Say you think Company ABC is overpriced at $50 a share. You borrow 100 shares from your broker—pay interest on the loan—and sell them for $5,000. Time ticks on, and as you suspected, the stock price falls. At $40 a share, you buy 100 shares for $4,000 and return them to your broker. You walk away $1,000 richer, minus investing costs.
That's a successful short. But what if the stock gains in popularity? Say the price rises to $60 a share, or $6,000 for those 100 shares you need to return. You're out $1,000.
Shorting, in short, is a strange transaction. You're selling something you don't own. And the goal is to sell high and then buy low, says Ryan Bend, co-portfolio manager of the Federated Prudent Bear Fund (BEARX), as opposed to the common game plan of first buying low then selling high.
Companies—and ultimately governments—get cranky when lots of folks bet on a downfall. Struggling Greece, for example, actually banned short-selling temporarily.
You probably don't need to be dancing around in your undies to know that this is, um, Risky Business, and not right for most individual investors.
When watching a sports game, would you bet on who's going to lose?
