Marine reserves have been widely promoted as conservation and fishery management tools. There are robust demonstrations of conservation benefits, but fishery benefits remain controversial. We show that marine reserves in Florida (United States) and St. Lucia have enhanced adjacent fisheries. Within 5 years of creation, a network of five small reserves in St. Lucia increased adjacent catches of ...
Gamma-aminobutyric acid (GABA) is an important inhibitory transmitter in central nervous system and is involved in pathophysiology of epilepsy. Pentylenete-trazole (PTZ), a convulsant agent, partly acts via anion channel of GABAA receptor. Ivermectin, an antiparasitic agent and a GABAA agonist, has anticonvulsant effect in animal seizure models. Cholestasis increases ...
St. Louis encephalitis virus infection was detected in summer 2015 in southern California after an 11-year absence, concomitant with an Arizona outbreak. Sequence comparisons showed close identity of California and Arizona isolates with 2005 Argentine isolates, suggesting introduction from South America and underscoring the value of continued arbovirus surveillance.
Since the heat-stable enterotoxin (ST) produced by yersinia enterocolitica is similar to enterotoxin production by E. coli, it is probably classified among toxinogenic bacteria. The culture filtrate of ST-producing strains of Y. enterocolitica is able to activate Guanylate cyclase and to increase fluid accumulation action of cylic Guanosin 3', 5' - monophosphate (cGMP) in sucking mouse intestin...
زمینه و هدف: برخی محققین معتقدند که تجویز گلوکز انسولین پتاسیم (GIK) در مبتلایان به انفارکتوس قلبی همراه با بالارفتن قطعه ST (STEMI) باعث کاهش مرگ و میر می گردد. اما برخی دیگر این یافته ها را نقض کرده اند. لذا این مطالعه با هدف بررسی اثرات محلول GIK بر پیامدهای کوتاه مدت بیماران مبتلا به STEMI انجام شده است. مواد و روش ها: کارآزمایی بالینی سه سوکور بر روی 72 بیمار مبتلا به STEMI در بخشCCU بیم...

Abstract Background: Conflicting data exist regarding the outcome of primary percutaneous coronary intervention, (PPCI) performed during the night hours. We sought to investigate this issue in a tertiary care center dealing with a high load of STEMI patients. Methods: Seventy three consecutive patients presenting with STEMI were divided in 2 groups with similar baseline characteristics. In-...
Neuroimaging findings in cases of St. Louis encephalitis (StLE) have yet to be reported despite the relatively high frequency of this entity. An epidemic permitted the documentation of isolated hyperintensity of the substantia nigra on T2-weighted images in two patients with StLE. This distribution of MR imaging abnormality in cases of StLE mirrors the reports presented in the literature that i...
conclusion st-vab and mgl-eb are reliable biopsy methods for microcalcifications. in proper indications, breast microcalcifications could be obtained by each method without missing diagnosis of breast cancer. objectives to evaluate the outcome of st-vab and mammography-guided localization and excisional biopsy (mgl-eb) for microcalcifications. patients and methods two radiologists retrospective...
