در قسمت اول این تحقیق یکسری برهمکنش های بین مولکولی با استفاده از محاسبات nmr مورد بررسی قرار گرفته اند. اثر استخلاف های مختلف در موقعیت های متا و پارا بر داده های nmr در کمپلکس های پیریدن استخلاف دار و هیدروژن فلوئورید مورد مطالعه قرار گرفت. مشخص شد که بین داده های nmr و قدرت الکترون دهندگی استخلاف ها یک همبستگی معناداری وجود دارد. از داده های aim نیز می توان برای پیش بینی داده های nmr استفاد...

Two antagonists of phosphoinositide 3-OH kinases (PI3Ks), LY294002 and Wortmannin, reduced the magnitude of the receptor potential in lobster olfactory receptor neurons (ORNs) recorded by patch clamping the cells in vivo. An antibody directed against the c-terminus of human PI3K-P110 beta detected a molecule of predicted size in the outer dendrites of the ORNs. Two 3-phosphoinositides, PI(3,4)P...

Microtubule-associated proteins can influence the organization, stability and dynamics of microtubules. We characterize a novel protein that associates with microtubules as assessed by immunofluorescence, immunoelectron microscopy, and co-sedimentation. The protein is expressed heavily in embryonic neurons and, to a lesser extent, in epithelial and mesodermal cells. The cDNA sequence predicts a...

Page 4 PSG Request for Datamining Abstract Parkinson’s disease (PD) has many paradoxes. For example, although smoking is highly associated with cancer and cardiovascular disease, smoking is associated with a much lower risk of PD (which itself is associated with a lower occurrence of cardiovascular disease). Whereas the apolipoprotein E ε4 allele is associated with higher risk of Alzheimer’s di...

The purpose of train detection systems is to check that related track section clear vehicles before a may be authorized pass through railroad. the important task for ensuring safety traffic. Multi-layer Perceptron classifier, which consists feedforward neural networks constructed multiple layers interconnected artificial neurons, proved effective trainset class classification in this study. Usi...

Mitochondria have been identified as targets of the neurotoxic actions of zinc, possibly through decreased mitochondrial energy production and increased reactive oxygen species accumulation. It has been hypothesized that impairment of mitochondrial trafficking may be a mechanism of neuronal injury. Here, we report that elevated intraneuronal zinc impairs mitochondrial trafficking. At concentrat...

Selective photothermolysis (SP) is a novel technique by which brief, unfocused laser pulses are selectively absorbed by, and cause selective thermal damage to, endogenously pigmented structures. The present experiments demonstrate the feasibility of using an exogenous non-fluorescent chromophore (procion blue) to effect cellular damage by SP. Dorsal root ganglia neurons in vitro were selectivel...

The retina of the goldfish grows throughout its life, in part, by the addition of new neurons at the margin. New ganglion cells added at the margin tend not to grow their dendritic arbors into the older, central retina. Hitchcock and Easter (J. Neurosci. 6, 1037-1050 (1986)) proposed that the dendrites of the new cells were prevented from extending centrally within the inner plexiform layer by ...

آلودگی های محیط زیست به عنوان یکی عوامل بیابان زایی، از مهم ترین چالش های جوامع صنعتی و در حال توسعه می باشد. با توجه به وجود مکان های معدنی متعدد مهم ترین علت بیابان زایی توسعه صنعتی (تکنوژنیک) در منطقه بافق، آلودگی ناشی از صنایع و معادن است. پژوهش حاضر با هدف تعیین آلاینده های پساب ناشی از فرآوری سنگ آهن در منطقه بافق انجام گردیده است. 16 نمونه طی سال های 1392-1389 از پساب مذکور تهیه و 18 متغ...

the padmakar-ivan (pi) index is a wiener-szeged-like topological index which reflectscertain structural features of organic molecules. the pi index of a graph g is the sum of alledges uv of g of the number of edges which are not equidistant from the vertices u and v. inthis paper we obtain the second and third extremals of catacondensed hexagonal systems withrespect to the pi index.
