Background: The objective of the current study was to determine the effect of activation of injected oocytes with dithiothreitol on development of ovine embryos derived from in vitro-matured oocytes and intracytoplasmic sperm.The injected oocytes with non-treated sperm were activated with 1) ionomycin (Io) + 6-dimethylaminopurine (6-DMAP) 2) DTT, 3) DTT+ ionomycin (I)+6-DMAP. Materials and Meth...
Introduction: Different studies have shown that there is no relation between sperm chromatin stability and fertilization rate in both IVF and ICSI patients. However, the relation between SDS tests, as a detergent, along with DTT as reducer of disulphide bridges has not been studied so far in ICSI patients. Since different concentrations of DTT can induce different degrees of sperm chromatin dec...
Background: Reduction/alkylation is one of the leading strategies for the development of antibody drug conjugates (ADCs). Precise control of the reduction process would not only yield a defined number of free thiols per antibody but also result in development of more homogenous conjugates. Methods: In the present study, we investigated the effect of various dithiothreitol (DTT) concentrations, ...
background hepatocytes are used as an in vitro model to evaluate drug metabolism. human hepatocyte transplant has been considered as the temporary treatment of acute liver failure. optimization freezing methods is very important to preserve both cell viability and function which are achieved by cryopreservation mostly always. objectives the present study aimed to investigate the cryoprotective ...
In spinal cord injury, axonal disruption results in motor and sensory function impairment. The evaluation of axonal fibers is essential to assess the severity of injury and efficacy of any treatment protocol, but conventional methods such as tracer injection in brain parenchyma are highly invasive and require histological evaluation, precluding clinical applications. Previous advances in magnet...
ATP/dithiothreitol (DTT)-stimulated guanylate cyclase (GC) in lung membrane was stimulated 18-fold by ATP and DTT, and both its activity and atrial natriuretic peptide (ANP)-stimulated GC activity were observed to be additive. ATP/DTT-stimulated GC was solubilized by octyl glucoside (OG) to examine the mechanism of ATP/DTT-stimulation. GC in OG-extracts was stimulated maximally 2.5-fold by both...
