Passive acoustic monitoring allows the assessment of marine mammal occurrence and distribution at greater temporal and spatial scales than is now possible with traditional visual surveys. However, the large volume of acoustic data and the lengthy and laborious task of manually analyzing these data have hindered broad application of this technique. To overcome these limitations, a generalized au...
فرسایش خاک توسط نیروی توأمان فرایندهای آب و باد سبب تخریب اراضی در سطحی گسترده می شود. بنابراین مدل سازی منطقه ای فرسایش پذیری یکی از مناسب ترین راهکارهای تخمین هدررفت خاک محسوب می گردد. لذا هدف از این پژوهش، تدوین یک مدل منطقه ای فرسایش پذیری توسط روش های آماری، از طریق رابطه سنجی بین پارامترهای فیزیکی خاک و شاخص های دورسنجی در خور و بیابانک است. روش نمونه برداری میدانی، از نوع ترانسکت خطی بود...
Self-estimates of intelligence (SEI), which influence to what extent people engage in and how well they perform at a task, are subject to distortion. Here, the distortion effects of individual differences in intelligence (IQ), gender, and proximal (with reference to test performance) and distal (with reference to IQ score distributions) assessments of SEI were tested in a sample of 200 British ...
Staphylococcal enterotoxins are exotoxins produced by Staphylococcus aureus that possess emetic and superantigenic properties. Prior to this research there were six characterized enterotoxins, staphylococcal enterotoxin types A to E and H (referred to as SEA to SEE and SEH). Two new staphylococcal enterotoxin genes have been identified and designated seg and sei (staphylococcal enterotoxin type...
فرسایش خاک متاثر از عوامل فرسایشپذیر و فرساینده است و مدلسازی منطقهای فرسایشپذیری میتواند معیاری برای برآورد میزان هدررفت خاک و تخریب اراضی محسوب شود. هدف از این پژوهش مدلسازی فرسایشپذیری در منطقه خوروبیابانک با استفاده از مؤلفههای فیزیکی خاک، فیزیونومی زمین و پوشش گیاهی از طریق روشهای تحلیل آماری است. بدین منظور ابتدا تعداد 33 نمونه خاک در امتداد سه ترانسکت از واحدهای پلایا تا کوهستا...
Oxidative damage and apoptosis are critical factors contributing to neuronal death during a stroke. The aim of the present study was to evaluate the neuroprotective effects of senkyunolide I (SEI) on focal cerebral ischemia-reperfusion (I/R) injury in rats, and investigate the underlying mechanisms. Male Sprague-Dawley rats were subjected to transient middle cerebral artery occlusion (tMCAO) fo...

The p34(SEI-1) oncoprotein is involved in a transcriptional regulation, cell cycle regulation, apoptosis, development and many other important cellular functions. Our present study suggests that p34(SEI-1) can promote metastasis by enhancing migration and invasion of cancer cells. Consistently, p34(SEI-1) expression was found to be increased as the tumor invasiveness progressed in human breast ...
A 34-KD protein encoded by the SEI-1 gene (p34(SEI‑1)), is a relatively recently discovered oncoprotein that has multiple important biological functions. Our data show that p34(SEI-1) enhances cancer cell survival and promotes tumorigenesis by downregulating the tumor suppressor PTEN, a negative regulator of the PI3K/AKT signaling pathway, and therefore activating the PI3K/AKT signaling pathway...
Amplification of SEI-1, a cell cycle regulatory gene at 19q13.1, is commonly detected in ovarian cancer, suggesting a role in the pathogenesis of ovarian cancer. In the present study, the oncogenic potential of SEI-1 was shown by anchorage-independent growth and tumor formation in nude mice with SEI-1-transfected NIH 3T3 mouse fibroblast cells. Silencing of SEI-1 gene expression by small interf...
