The nonprotective OLV was associated with significantly smaller degrees of collapse and overdistension in the ventilated lung (P < 0.001).

"value": "Question: How many TAp73 isoforms have been identified in humans?\nText: <answer> 7 <context> Human delta Np73 regulates a dominant negative feedback loop for TAp73 and p53. Inactivation of the tumour suppressor p53 is the most common defect in cancer cells. p53 is a sequence specific transcription factor that is activated in response to various forms of genotoxic stress to induce cell cycle arrest and apoptosis. Induction of p53 is subjected to complex and strict control through several pathways, as it will often determine cellular fate. The p73 protein shares strong structural and functional similarities with p53 such as the potential to activate p53 responsive genes and the ability to induce apoptosis. In addition to alternative splicing at the carboxyl terminus which yields several p73 isoforms, a p73 variant lacking the N-terminal transactivation domain (Delta Np73) was described in mice. In this study, we report the cloning and characterisation of the human Delta Np73 isoforms, their regulation by p53 and their possible role in carcinogenesis. As in mice, human Delta Np73 lacks the transactivation domain and starts with an alternative exon (exon 3'). Its expression is driven by a second promoter located in a genomic region upstream of this exon, supporting the idea of two independently regulated proteins, derived from the same gene. As anticipated, Delta Np73 is capable of regulating TAp73 and p53 function since it is able to block their transactivation activity and their ability to induce apoptosis. Interestingly, expression of the Delta Np73 is strongly up-regulated by the TA isoforms and by p53, thus creating a feedback loop that tightly regulates the function of TAp73 and more importantly of p53. The regulation of Delta Np73 is exerted through a p53 responsive element located on the Delta N promoter. Expression of Delta Np73 not only regulates the function of p53 and TAp73 but also shuts off its own expression, once again finely regulating the whole system. Our data also suggest that increased expression of Delta Np73, functionally inactivating p53, could be involved in tumorogenesis. An extensive analysis of the expression pattern of Delta Np73 in primary tumours would clarify this issue."

"value": "Answer: Chorea\nExplanation: Ans. A. Relapse of multiple sclerosisThe onset of a new movement disorder during pregnancy suggests chorea gravidarum, a variant of Sydenham's chorea associated with rheumatic fever and streptococcal infection; the chorea may recur with subsequent pregnancies. Patients with preexisting multiple sclerosis experience a gradual decrease in the risk of relapses as pregnancy progresses and, conversely, an increase in attack risk during the postpartum period. Beta interferons should not be administered to pregnant MS patients, but moderate or severe relapses can be safely treated with pulse glucocorticoid therapy. Finally, certain tumors, particularly pituitary adenoma and meningioma, may manifest during pregnancy because of accelerated growth, possibly driven by hormonal factors.Peripheral nerve disorders associated with pregnancy include Bell's palsy (idiopathic facial paralysis), which is approximately threefold more likely to occur during the third trimester and immediate postpartum period than in the general population."

Therefore, the present study aimed to examine the associations of time, effort, time spent cooking and cooking skills with fast food and take-away food consumption.', 'Between May and June 2009, a random postal survey was sent out to 2323 Swiss households. The response rate was 44% (n = 1017).

"value": "Answer: An increased fibrinogen level\nExplanation: The clinical history and blood smear findings (fragmented cells and few platelets) presented in the question are typical of DIC. The disorder, which can be triggered by endotoxin shock, results ultimately in the initiation of the intrinsic clotting mechanism and the generation of thrombin (prolonged PT and PTT, decreased fibrinogen concentration, and an increase in fibrin split products). Fibrin deposited in the microcirculatory system can lead to tissue ischemia and necrosis, further capillary damage, release of thromboplastic substances, and increased thrombin generation. Simultaneous activation of the fibrinolytic system produces increased amounts of fibrin split products, which inhibit thrombin activity. Of utmost importance in the treatment of children who have DIC is the management of the condition that precipitated the disorder."

An understanding of the factors that influence the yield of such mutations is important for management of adverse effects of perinatal exposures. Resistance to 6-thioguanine (6-TG) can be utilized to study mutational events at the hypoxanthine-guanine phosphoribosyl transferase (HGPRT) locus. HGPRT is X-linked and recessive. According to the Lyon hypothesis, male cells have only one X-chromosome and female cells randomly inactivate the second X-chromosome. This leads to the prediction that X-linked genes should be equally sensitive to the mutagenic effects of toxicants in male and female fetuses.', 'We tested this supposition by in utero exposure of Syrian hamster fetuses to N-ethyl-N-nitrosourea (ENU) at day 12 of gestation.

The glycemic index of starch varies between near 1 (or 100%) and near 0 as a result of variable rates of hydrolysis, and that of nonstarch polysaccharides is 0. \nFoods that have a low glycemic index are considered to be more beneficial, since they cause less fluctuation in insulin secretion.\n\nRef: Harper’s illustrated biochemistry, 31st edition."
