Comparison of different freezing rates on post-thaw viability, proliferation, and stemness of sheep spermatogonial stem cells.

The application of spermatogonial stem cells (SSC) will be more effective and feasible following the successful cryopreservation and transfer of SSCs in livestock. Like other cells, SSCs are also sensitive to cryoinjury; hence composition of the cryomedia and freezing protocols need to be optimized. The present study aims to optimising the best freezing rates by minimising the ice crystallization and dehydration effect in order to maximize the post-thaw SSCs survivability and stemness characteristics.

High Diagnostic Accuracy of Arterial Phase CT in Differentiating Pheochromocytoma in Good/Poor Washout Adrenal Masses.

For predicting the success of complex traits like male fertility, identification of hub genes involved in various sperm functions are essential. The bulls from the transcriptome profiled samples (n = 21), were grouped into good and poor progressive motility (PM), acrosome integrity (AI), functional membrane integrity (FMI) and fertility rate (FR) groups.

Successful Use of Cefiderocol to Treat a Multidrug-resistant Stenotrophomonas maltophilia Ventilator-associated Pneumonia in an Extremely Preterm Neonate.

Background: Ventilator-associated pneumonia (VAP) caries a morbidity and mortality risk in the preterm neonate, particularly in the context of rising global antimicrobial resistance driving infections due to multidrug-resistant Gram-negative bacteria. Cefiderocol, a siderophilic cephalosporin, has broad Gram-negative antimicrobial activity and central nervous system penetration and is used for the treatment of hospital-acquired pneumonia or VAP in adults. Scarce data exists on its use in neonates.

Relationship among seminal antigenicity, antioxidant status and metabolically active sperm from Holstein-Friesian () bulls.

Sperm antigenicity has been implicated as a regulatory factor for acquiring fertilizing competence in the female reproductive tract. Overt immune response against the sperm proteins leads to idiopathic infertility. Hence, the aim of the study was to evaluate the influence of the auto-antigenic potential of sperm on the antioxidant status, metabolic activities and reactive oxygen species (ROS) in bovine.

Cryostress induces fragmentation and alters the abundance of sperm transcripts associated with fertilizing competence and reproductive processes in buffalo.
