Athletic left ventricular hypertrophy: long-term studies are required.
lar hypertrophy regresses if athletes decondition; left ventricular systolic function and Doppler measured mitral diastolic filling patterns are usually normal; and, lastly, follow-up studies of elite international standard competitors suggest that they live longer than expected compared to the population mean. However, athletic left ventricular hypertrophy does not only occur in Olympic standa...
متن کاملMultiple extracellular signals are required for long-term oligodendrocyte survival.
We showed previously that oligodendrocytes and their precursors require continuous signalling by protein trophic factors to avoid programmed cell death in culture. Here we show that three classes of such trophic factors promote oligodendrocyte survival in vitro: (1) insulin and insulin-like growth factors (IGFs), (2) neurotrophins, particularly neurotrophin-3 (NT-3), and (3) ciliary-neurotrophi...
متن کاملSuccessful endoscopic band ligation of duodenal Dieulafoy's lesions. Further large controlled studies are required.
Dieulafoy’s lesion (DL) is an abnormal arterial lesion in the digestive tract. We report a 21-year-old male, without any relevant his past medical and familiar history. He admitted to the ER with a history of hematemesis and melena. An upper endoscopy showed a protruding vessel without surrounding venous dilatation, active bleeding or mucosal defect. This vascular lesion was located in the ante...
متن کاملAssociation of TNFRSF1B Promoter Polymorphisms with Human Disease: Further Studies Examining T-Regulatory Cells Are Required
The TNFR2 receptor is expressed by highly active regulatory T cells, and thus constitutes an important therapeutic target for the treatment of autoimmune disease and cancer. Disease susceptibility as well as the potential response to therapies directed at TNFR2 could be significantly impacted by genetic variation in the promoter of the TNFRSF1B gene that codes for the TNFR2 protein. To date, on...
متن کاملTyrosine phosphorylation sites in ephrinB2 are required for hippocampal long-term potentiation but not long-term depression.
Long-lasting changes in synaptic function are thought to be the cellular basis for learning and memory and for activity-dependent plasticity during development. Long-term potentiation (LTP) and long-term depression (LTD) are two opposing forms of synaptic plasticity that help fine tune neural connections and possibly serve to store information in the brain. Eph receptor tyrosine kinases and the...
