Reactive oxygen species (ROS) induce chemokines responsible for the recruitment of inflammatory cells to sites of injury or infection. Here we show that the plasma membrane Ca2+-permeable channel TRPM2 controls ROS-induced chemokine production in monocytes. In human U937 monocytes, hydrogen peroxide (H2O2) evokes Ca 2+ influx through TRPM2 to activate Ca2+dependent tyrosine kinase Pyk2 and ampl...

در این مقاله یک سیستم کنترل مد لغزشی برای سیستم فرود خودکار هواپیما با دینامیک خطی شده بر اساس تنظیمکنندههای خطی مرتبه دوم در حضور اغتشاشات ناشی از بارهای آئرودینامیکی طراحی شده است. در سیستم کنترل مد لغزشی برای به دست آوردن قانون کنترلی نیاز به معکوس پذیری ماتریس ورودی هست، اما در اکثر سیستم های واقعی به دلیل برابر نبودن تعداد ورودیها با تعداد حالتهای سیستم این ماتریس مستطیلی است. به همی...
When presented with random-dot displays with little depth information, observers cannot determine their direction of self-motion accurately in the presence of rotational flow without appropriate extra-retinal information (Royden CS et al. Vis Res 1994;34:3197-214.). On theoretical grounds, one might expect improved performance when depth information is added to the display (van den Berg AV and ...
Integrins mediate cell adhesion, migration, and survival by connecting intracellular machinery with the surrounding extracellular matrix. Previous studies demonstrated the importance of the interaction between β(3) integrin and VEGF type 2 receptor (VEGFR2) in VEGF-induced angiogenesis. Here we present in vitro evidence of the direct association between the cytoplasmic tails (CTs) of β(3) and V...
We describe a parameterized family of genetic algorithms for efficient front calculations under uncertainty. Parameters for the algorithms all have clear statistical meaning and serve to reduce the overall computational effort and to ensure solution quality and diversity in the solution set.
