هدف از انجام تحقیق حاضر، بررسی اثر آلبومین سرم گاوی (BSA) بر تحرک و باروری اسپرم خروس با استفاده از 20 قطعه خروس و 48 قطعه مرغ بومی بود. منی جمعآوری شده از خروسها با هم مخلوط شدند. برای آزمایش اول، منی مخلوط پس از رقیقسازی به چهار قسمت تقسیم شد. تیمارها عبارت بودند از منی رقیق شده بدون BSA و دارای یک درصد BSA. در هر گروه، ارزیابی تحرک اسپرم طی 30 دقیق پس از اسپرمگیری و 24 ساعت پس از نگهداری...
BACKGROUND Gold nanoclusters (AuNCs) are typically composed of several to tens of gold atoms which are stabilized with biomacromolecules such as bovine serum albumin (BSA). Au NCs fluoresces in the visible to near infrared region, in a size-dependent manner. AuNCs solutions have potential as fluorophore in a wide range of biomedical applications such as biodetection, biosensing and bioimaging i...
BACKGROUND Body surface area (BSA) is a biometric unit to measure the body size. Its clinical significance in video-assisted thoracoscopic surgery (VATS) was rarely understood. We aimed to estimate the predictive value of BSA for surgical complications following VATS anatomical resections for lung adenocarcinoma (LAC). METHODS A single-center retrospective analysis was performed on the consec...
The effect of culture system and protein supplementation on the development of one-cell porcine embryos was investigated. One hundred and sixty-four one-cell embryos were collected at slaughter from 19 handmated gifts. Culture systems evaluated were microdrops of Whitten's medium (WM) under paraffin oil (M) or tubes with 4.0 ml of WM (T). Also tested was T with a 2.0 ml paraffin oil overlay (O)...
We discussed the bonding of O2 to hemoglobin using results of ab initio calculations of idealized portions of the Hb molecule. The bond between Fe and O2 is formed by coupling a triplet state (intermediate spin state) of Fe to the triplet ground state of O2 (analogous to the bonding of O to O2 in ozone). The coordination sphere of the Fe reduces the energy separation between the quintet, triple...
During protein crystallization and purification, proteins are commonly found in concentrated salt solutions. The exact interplay of the hydration shell, the salt ions, and protein–protein interactions under these conditions is far from being understood on a fundamental level, despite the obvious practical relevance. We have studied a model globular protein (bovine serum albumin, BSA) in concent...
