Supplementation of lake extender with cysteamine preserves quality parameters and fertility potential of post-thawed rooster sperm during cryopreservation process.

Background: In the cryopreservation process, rooster spermatozoa are vastly sensitive to reactive oxygen species (ROS). This study aimed to investigate the effects of Lake extender supplemented via Cysteamine (CYS) on the quality and fertility characteristics of rooster semen during the cryopreservation process.

Methods: Semen samples were collected from 10 proved Ross-308 roosters, diluted and cryopreserved in the Lake extender which contained 0, 1, 2, 4, and 8 mM of CYS (C-0, C-1, C-2, C-4, and C-8, respectively).

The effects of mitoquinol mesylate on post-thaw characteristics and fertilizing ability of rooster semen cryopreserved in the Beltsville medium.

Cryopreservation of rooster semen is a reproductive technology carried out to boost genetic gain and productivity in commercial flocks of chicken. However, semen freezing significantly reduces the quality and fertilizing potential of spermatozoa. This study examined cryoprotective effects of the mitochondria-targeted antioxidant mitoquinol mesylate added to the freezing extender by assessing post-thaw characteristics of rooster sperm.

The effect of self-regulatory program based on Leventhal's model on the illness perception and resilience of people with multiple sclerosis.

Backgrounds: The study at hand seeks to examine the influence of a self-regulation program rooted in Leventhal's model on the illness perception and resilience of patients with multiple sclerosis (MS). By exploring the impact of Leventhal's model-based interventions, healthcare professionals can enhance their ability to effectively address the challenges associated with this disease. In addition, this research endeavor can serve as a valuable resource for the development of nursing knowledge in the realm of MS patient care.

Supplementation of Plant-Based Freezing Extender With Cysteamine Preserves Quality Parameters and Fertility Potential of Buck Sperm During Cryopreservation Process.

Sperm cryopreservation in small ruminant is an efficient strategy to distribute spermatozoa for reproductive programmes, but this process reduces the fertility potential of frozen-thawed spermatozoa. The aim of the current research was to evaluate the impact of different concentrations of cysteamine (CYS) in soybean lecithin (SL)-based medium on postthawed buck semen quality and fertility potential. Semen samples were collected from five bucks, twice a week, then diluted in the SL-based extender containing different concentrations of CYS as follows: extender containing 0 mM (control, C0), 1 mM (C1), 2 mM (C2), 4 mM (C4) and 8 mM (C8) CYS.
