in this paper a fast and novel stability-indicating ultra fast lc method for separation and estimation of impurities in clopidogrel and aspirin in their combined tablet dosage form and omeprazole was developed. the separation of usp related substances of clopidogrel (a, b and c), aspirin (d), omeprazole (a, b and c) and few other unknown impurities was detected by using ultra fast liquid chroma...
BACKGROUND The study of complex biological networks and prediction of gene function has been enabled by high-throughput (HTP) methods for detection of genetic and protein interactions. Sparse coverage in HTP datasets may, however, distort network properties and confound predictions. Although a vast number of well substantiated interactions are recorded in the scientific literature, these data h...
Clock distribution networks consume a considerable portion of the power dissipated by synchronous circuits. In conventional clock distribution networks, clock buffers are inserted to retain signal integrity along the long interconnects, which, in turn, significantly increase the power consumed by the clock distribution network. Resonant clock distribution networks are considered as efficient lo...
This study presents a novel mathematical modeling framework that is uniquely suited to investigating the structure and dynamics of the sleep-wake regulatory network in the brain stem and hypothalamus. It is based on a population firing rate model formalism that is modified to explicitly include concentration levels of neurotransmitters released to postsynaptic populations. Using this framework,...
Electrically tunable liquid crystal microlenses have attracted strong research attention due to their advantages of tunable focusing, voltage actuation, low power consumption, simple fabrication, compact structure, and good stability. They are expected to be essential optical devices with widespread applications. However, the slow response time of nematic liquid crystal (LC) microlenses has bee...
The locus coeruleus (LC) nucleus modulates adaptive behavioral responses to stress and dysregulation of LC neuronal activity is implicated in stress-induced mental illnesses. The LC is composed primarily of noradrenergic neurons together with various glial populations. A neuroglia cell-type largely unexplored within the LC is the NG2 cell. NG2 cells serve primarily as oligodendrocyte precursor ...
Langerhans cells (LCs) constitute a network of immune sentinels in the skin epidermis that is seeded during embryogenesis. Whereas the development of LCs has been extensively studied, much less is known about the homeostatic renewal of adult LCs in "nonmanipulated" animals. Here, we present a new multicolor fluorescent fate mapping system and quantification approach to investigate adult LC home...
Urodynamic status must interact with arousal and attentional processes so that voiding occurs under appropriate conditions. To elucidate the central encoding of this visceral demand, multisite recordings were made within a putative pontine-cortical micturition circuit from the pontine micturition center (PMC), locus coeruleus (LC) and medial prefrontal cortex (mPFC) during cystometry in unanest...
Based on the self-biased current-reuse complementary structure and interposed network, a low power LC voltage controlled oscillator (VCO) is presented, which can simultaneously achieve ultra-low power consumption and low phase noise. Firstly, thanks to the self-biased voltage-diving technique, the LC-VCO consumes ultra-low power consumption. Secondly, the novel interposed network can greatly im...
مطالعات گذشته نشان داده اند که به دنبال محرومیت اوپیاتی، فعالیت خودبخودی نورون های هسته لوکوس سرولئوس (lc) به شدت افزایش می یابد. مجموعه ای از عوامل درونی و همچنین عوامل بیرونی تحریکی در فرآیند بیش فعالی نورون های هسته lc در شرایط محرومیت اوپیوئیدی دخیل می باشند. از آنجایی که هسته پاراژیگانتوسلولاریس (pgi) دارای مهمترین ورودی های تحریکی به هسته lc می باشد؛ از اینرو دارای نقش مهمی در بیش فعالی ن...
