the n-methyl-d-aspartic acid (nmda) receptor is one of the specific types of ionotropic receptors which lied to glutaminergic system. it has been widely accepted that nmda receptor neurons promote anxiety, in humans as well as in animal models. however, in the previous study seems inhibiting of this receptors decreased the protective role in neural cell. demonstration of nmda receptor activity ...
In this paper, we examine the singlet scalar dark matter annihilation to becoming the Standard Model particles in the non-commutative space. In the recent decades, many candidates of dark matter have been offered, but our information about the nature of dark matter is still limited. There are such particle candidates as scalar matetr, fermion, boson, gauge boson, etc.; however, they have nei...
اشیاء اطراف ما در دمای اتاق بیشتر انرژی خود را بصورت تشعشعات مادون قرمز گسیل می کنند از این رو آشکارسازهای مادون قرمز از اهمیت ویژه ای برخوردار هستند و بهبود پارامترهای آشکارسازی همواره یکی از چالش های محققین بوده است. ساختارهای پیشنهادی برای آشکارسازها از ساختار توده ای شروع شد. در دماهای بالا انرژی گرمایی در مقایسه با انرژی فوتون های مادون قرمز قابل قیاس می گردد. در نتیجه جریان تاریک که ناشی ...
In the current paper, we have studied the effect of dark energy on for-mation where dark energy exists in the background. For this purpose, we used both WMAP9 and Planck data to study how the radius changes with redshift in these mod-els. We used different data sets to fix the cosmological parameters to obtain a solution for a spherical region under collapse. The mechanism of structure formation f...
This paper proposes an improved dark channel prior for removing haze from images. Dark channel prior is an effective method for removing haze. Dark channel is an image in the same size as the hazy image which is obtained by dividing the RGB images into windows and for each window, the minimum of each R, G and B channels are calculated. Then again the minimum of these three values is calculated ...
the morphology of retinal photoreceptor layer was studied in continuous light-exposed and dark-adapteddomestic male cats (felis catus). the eyes of 12 healthy adult cats (4 in continuous light-exposed group, 4 in continuous dark-adapted group, and 4 in control group) were routinely fixed and studied by electron microscope. results showed that the general structure of photoreceptor layer in this...
objective: previously, analgesic, hypnotic, and anticonvulsant effects have been suggested for rosa damascena (r. damascena). in the present study, possible anti-seizure and neuro-protective effects of hydro-alcoholic extract of r. damascena has been investigated after inducing seizures in rats by pentylenetetrazole (ptz). materials and methods: the rats were divided to five groups: (1) control...
introduction: dark neurons which their morphological characteristics are consistent with those of cells undergoing apoptosis, are generated as an acute or delayed consequence of several pathological situations. the present study was designed to evaluate whether inflammatory pain regarding the role of no and jnk lead to the formation of dark neurons in the dorsal horn of the lumbar spinal cord i...
