| multi | Chromosomal mutation can't be identified by Agarose gel electrophoresis Agarose Gel electrophoresis Used to separate the DNA by charge or by size. The smaller the fragment, the more rapid the migration. Overall rate of migration and optimal range of size for separation are determined by the chemical nature of the gel and by the degree of its crosslinking. Highly cross-linked gels optimize the separation of small DNA fragments. The dye ethidium bromide forms a brightly fluorescent color as it binds to DNA, and so small amounts of separated DNA fragments can be photographed on gels. Specific DNA fragments can be recognized by probes containing complementary sequences. Usually performed to visualize the amplified DNA after PCR, but may be used as a preparative technique prior to use of other Just a method of visualizing the DNA after separating by size. So it is always used as a pa of any molecular method to visualize the DNA.

| single | Atrial A and B receptors are located at the venoatrial junctions and have distinct functions. Type A receptors react primarily to hea rate but adapt to long-term changes in atrial volume. Type B receptors increase their discharge during atrial distension. C fibers arise from receptors scattered through the atria; these discharge with a low frequency and respond with increased discharge to increase in atrial pressure. The A and B receptors are thought to mediate the increase in hea rate associated with atrial distension (such as can occur with intravenous infusions) known as the Bainbridge reflex. In contrast, activation of atrial C fibers generally produces a vasodepressor effect (bradycardia and peripheral vasodilation). Ref: Hoit B.D., Walsh R.A. (2011). Chapter 5.

| single | Ans. A. Prostate cancerProstate cancer leads to osteosclerotic metastasis because of release of PTH like proteinsa. Prostate carcinoma cells secrete factors that directly and indirectly alter the osteoblastic function and express factors critical for normal bone development and remodeling, including bone morphogenetic proteins (BMPs), TGF-b, platelet- derived growth factor, adrenomedullin, insulin-like growth factor (IGF-1), fibroblast growth factor and vascular endothelial growth factor (VEGF).b. The osteolytic factor, PTHrP, is also abundantly expressed in Prostate carcinoma metastases, despite the fact that these lesions are primarily blastic. It has been demonstrated that PTHrP increases osteoblastic progenitor cell proliferation and induces early Osteoblastic differentiation.c. Another study says that Wants (a large family of proteins that promote bone growth) contribute to prostate cancer- mediated osteoblastic activity. Prostate cancer bone metastases have both an osteolytic and osteoblastic component, there is a shift in the balance from osteolytic to osteoblastic activity as prostate cancer progresses, which results in osteosclerotic (Osteoblastic) metastasis. | Orthopaedics | Bone Tumour |

| single | Ans is Eale's disease Both Eale's disease and Retinal detachment are causes of painless sudden loss of vision, however Eale's disease is a much more common cause than RD in a young male. Ocular and systemic examinations in both the conditions may be normal.Eale's diseaseIt is a disease of young adult males, who otherwise are healthy, in developing countries (especially India).It is an idiopathic inflammation of peripheral retinal veins; characterized by recurrent vitreous hemorrhage.(Periphlebitis leads to obliteration of the affected vessels. Hypoxia leads to neovascularization which lead to recurrent vitreous hemorrhage)The etiology is unknown. Hypersensitivity to tuberculin protein has been reported, however no clear relationship to tuberculosis has been found.Usually bilateral.The common presenting symptoms are sudden appearance of floaters or painless loss of vision.The vitreous hemorrhage clears spontaneously, but after a few recurrence the hemorrhage may organize, and may cause fractional retinal detachment or secondary glaucoma.Treatment:systemic steroids in early vasculitis stageLaser photocoagulation for abnormal vessels is used in neovascularization stagevitreoretinal surgery is required for marked vitreous traction threatening the macula.Causes of sudden, painless loss of visionUnilateralBilateralSubluxation or dislocation of lensVitreous hemorrhageRetinal hemorrhageRetinal detachmentRetinal vascular occlusionExudative age-related macular degenerationPosterior uveitis Diabetic retinopathyGrade IV hypertensive retinopathy with macular star Atypical optic neuritis Toxic optic neuropathy Bilateral occipital infarction | Ophthalmology | Vitreous Haemorrhage Vitrectomy |

| single | * Transposons, also called jumping genes, are pieces of DNA that move readily from one site to another.* They move either within or between the DNAs of bacteria, plasmids and bacteriophages in a manner, that plasmid genes can become part of the chromosomal complement of genes.* Interestingly, when transposons transfer to a new site, it is usually a copy of the transposon that moves, while the original remains in situ (like photocopying).* Transposons can code for metabolic or drug resistance enzymes and toxins. They may also cause mutations in the gene into which they insert or alter the expression of nearby genes.* In contrast to plasmids or bacterial viruses, transposons cannot replicate independently of the recipient DNA. More than one transposon can be located in the DNA for example, resistance genes. Thus, transposons can jump from:# The host genomic DNA to a plasmid# One plasmid to another# A plasmid to genomic DNA.* An insertion sequence is a short DNA sequence that acts as a simple transposable element. Insertion sequences have two major characteristics: they are small relative to other transposable elements (generally around 700 to 2500bp in length) and only code for proteins implicated in the transposition activity (they are thus different from other transposons, which also carry accessory genes such as antibiotic resistance genes. | Pathology | Neoplasia |

ab32941a-6551-44a8-96cf-f1e60d6f7ea2 | Max risk of stroke after TIA: | First 48 hours | First week | First month | First year | 0a
| single | Ans. a. First 48 hoursTransient ischemic attack (TIA) is sudden, transitory loss of neurologic function that comes on without headache and resolves spontaneously within 24 hours (but usually lasts less than 1 hour), leaving no neurologic sequelae.The specific symptoms depend on the area of the brain affected, which is in turn related to the vessels involved. The most common origin is high-grade stenosis (>=70%) of the internal carotid, or ulcerated plaque at the carotid bifurcation.Stroke may be indistinguishable from a TIA at the time of presentation: Duration of symptoms is the determining difference.Symptoms are transient with a TIA because reperfusion occurs, either because of collateral circulation or because of the breaking up of an embolus.The blockage in blood flow does not last long enough to cause permanent infarction.Once a patient has a TIA, there is a high risk of stroke in 10-15% in the first 3 months, with most events occurring in the first 2 days. The risk of a stroke in a patient with a history of TIA is about 10% per year. TIAs carry a 30% 5-year risk of stroke. Therefore, cardiac risk factors should be closely investigated and, if possible, eliminated in a patient who has had a TIA.Cases may present only with transient loss of vision in one eye, known as amaurosis fugax. This happens during a transient ischemic attack because the first branch of the internal carotid artery is the ophthalmic artery.Note:TIAs are never due to hemorrhage; hemorrhages do not resolve in 24 hours.The importance of TIAs is that they are predictors of stroke, and timely elective carotid endarterectomy may prevent or minimize that possibility.Workup starts with.noninvasive Duplex studies.Carotid endarterectomy is indicated if the lesions are found in the location that explains the neurologic symptoms.Angioplasty and stent can be performed in high risk surgical patients | Medicine | C.N.S. |
