Sulforaphane inclusion in a freezing medium augments post-thaw motility, functional and biochemical features, and fertility potential of buffalo (Bubalus bubalis) spermatozoa.

Sulforaphane is a natural and highly effective antioxidant safeguarding the reproductive system, and alleviate oxidative stress. This study was designed in order to elaborate L-sulforaphane effect on semen quality, biochemical parameters, and fertility of buffalo (Bubalus bubalis) spermatozoa. Semen was collected from five buffalo bull with artificial vagina (42 °C) three times and evaluated for volume, consistency (color), motility, and sperm concentration.

Pharmacological Progress of Mitophagy Regulation.

With the advancement in novel drug discovery, biologically active compounds are considered pharmacological tools to understand complex biological mechanisms and the identification of potent therapeutic agents. Mitochondria boast a central role in different integral biological processes and mitochondrial dysfunction is associated with multiple pathologies. It is, therefore, prudent to target mitochondrial quality control mechanisms by using pharmacological approaches.

The ameliorating effects of crocetin on frozen-thawed quality, and fertility via attenuating oxidative status of bubaline spermatozoa.

Current study was conducted to appraise the cryoprotective influence of crocetin on quality, oxidative status, and fertility potential of bubaline spermatozoa. Collected semen from four bulls was diluted in five aliquots with (10 μM, 5 μM, 2 μM, 1 μM, and control [0 μM] supplementation of crocetin). After gentle dilution (37 °C), cooling (4 °C, in 2 h), equilibration (4 °C, for 4 h) and packaging of samples was done in straws (polyvinyl French, 0.

Improving the quality and in vitro fertilization rate of frozen-thawed semen of buffalo (Bubalus bubalis) bulls with the inclusion of vitamin B in the cryopreservation medium.

This study was designed to evaluate the effects of vitamin B in cryopreservation medium on frozen-thawed semen of buffalo (Bubalus Bubalis) bulls. Semen from five bulls (fertility-proven) were diluted in five aliquots not supplemented (control), or supplemented with 1, 2, 4, or 5 mg/mL of vitamin B and evaluated using the Computer Assisted Sperm motion Analysis, antioxidant enzymes, lipid peroxidation (LPO), reactive oxygen species (ROS), ATP concentrations, and in vitro fertilization rate (%). Sperm progressive motility, rapid velocity (%), mitochondrial potential, and acrosome integrity were greater (P < 0.

Epigallocatechin-3-gallate (EGCG) addition as an antioxidant in a cryo-diluent media improves microscopic parameters, and fertility potential, and alleviates oxidative stress parameters of buffalo spermatozoa.

The disparity between the endogenous antioxidants concentration and free radicals in spermatozoa results in reactive oxygen species (ROS) generation. In this prospect, epigallocatechin-3-gallate (EGCG) preserves vigorous antioxidant features. Current study explored the influence of EGCG in a cryo-diluent media on microscopic parameters, oxidative stress parameters, and fertility potential of buffalo spermatozoa during cryopreservation.

Comparative phylogenetic analysis of and with other members of subfamilies of cyprinidae on the basis of complete mitochondrial genome and 12S, 16S ribosomal RNA from Northren areas of Pakistan.

We assessed the relationship of Schizothoracinae species with other subfamilies Alburninae, Xenocyprinae, Cultrinae and Squaliobarbinae of family Cyprinidae by creating the phylogenetic trees using complete mitogenome and 12S and 16S RNA. Our representative species show the great affiliation with other but separated from a group composed of , , and of subfamily Alburninae while other subfamilies formed distinct group. The members of subfamily Schizothoracinae shows separate line of evolution from subfamily Barbinae.

Supplementation of l-tryptophan (an aromatic amino acid) in tris citric acid extender enhances post-thaw progressive motility, plasmalemma, mitochondrial membrane potential, acrosome, and DNA integrities, and in vivo fertility rate of buffalo (Bubalus bubalis) bull spermatozoa.
