PURPOSE Recent studies revealed that immunological mechanisms play a prominent role in the pathogenesis of proliferative diabetic retinopathy (PDR). Given the importance of the immune response in PDR and the significance of the programmed death 1 (PD-1) pathway as an immune regulatory pathway, the aim of this study is to determine the expression and functional characteristics of the PD-1 pathwa...
In this research paper, we propose supervised and unsupervised change detection methodologies focused on the analysis of multitemporal Synthetic Aperture Radar (SAR) images. These approaches are based on three main steps: (1) a comparison of multitemporal image was carried out by normalized difference ratio (NDR) operator; (2) implementing a novel supervised or unsupervised thresholding and (3)...
PURPOSE Trans-signaling of interleukin (IL)-6 through its soluble receptor (sIL-6R) is critically involved in the promotion of chronic inflammatory diseases. The aim of the present study was to estimate IL-6, sIL-6R, and soluble gp130 (sgp130, a natural antagonist of IL-6 trans-signaling) concentrations in the serum and aqueous humor (AqH) of patients with diabetic retinopathy (DR). METHODS P...
Spintronic logic devices have attracted attention because of the prospect breaking von Neumann bottleneck through nonvolatile in-memory computing. Although varieties spin Boolean gates been proposed, spintronic arithmetic units such as adders not extensively studied difficulties in application cascade method CMOS-based devices. We experimentally demonstrated a full adder based on anomalous Hall...
When constant light is 18, 21, or 24 hr, a constant light to constant darkness (LL/DD) transition in vitro results in a phase difference (delta psi) between an eye that is attached to the cerebral ganglion and its partner that is detached by cutting its optic nerve just prior to the LL/DD. This delta psi develops during the first 24 hr after LL/DD as the result of efferent activity in the optic...
در این پایان نامه واپاشی های هادرونی d_s^+???^+ و b_0?d^* (2007) k^* (892) به روش فاکتوری کردن qcd در حد کوارک سنگین بررسی شده است. سهم های فاکتور نشدنی، شامل تصحیحات ورتکسی و سهم های ناظر سخت ، مورد بحث قرار گرفته اند و نتایج عددی آنها را در طرح ndr و در دو حالت فاکتوری کردن ساده و فاکتوری کردن qcd در فصل چهارم، ارائه نموده ایم. پیش بینی نسبت انشعابی واپاشی ها با مقادیر تجربی سازگاری مناسبی دا...
