The effects of vitamin E supplementation on sperm parameters, chromatin integrity, and gene expression before and after freezing in aged mice.

Objective: Some age-related testicular changes, such as Sertoli cell vacuolization and blood-testis barrier breakdown, reduce total sperm production and male fertility. Therefore, this study investigated the effect of vitamin E on restoring testicular function in aged mice. Sperm cryo-resistance was also assessed.

Use of Worms to Produce Peptone for Vaccine Production.

Concurrent with an increase in the human population on the earth, more than ever, the creation of energy and maintenance of health is necessary, and nowadays, various sources of energy supply are being developed. The general global view in this regard is to provide protein and energy from available and cheap sources. Iran is no exception to this general rule, only in the field of ensuring the health of livestock resources every year, about 10 tons of peptone is needed for producing clostridial vaccines.

Optimization and scale-up of Clostridium perfringens type D culture and epsilon-toxin production: Effects of stirring, glucose and pH adjustment.

The effects of some main bacteria culture parameters including mixing rate, glucose (GC) concentration, steps of GC addition, and steps of pH adjustment on both C. perfringens bacteria growth and its epsilon toxin production in a bench-scale 20-L glass carboy were investigated. The optimized mixing rate of 300 rpm, GC concentration of 4 g L, and 3-step addition of GC resulted in the bacteria and toxin concentrations of 0.

Privacy-preserving federated learning for scalable and high data quality computational-intelligence-as-a-service in Society 5.0.

Training supervised machine learning models like deep learning requires high-quality labelled datasets that contain enough samples from various categories and specific cases. The Data as a Service (DaaS) can provide this high-quality data for training efficient machine learning models. However, the issue of privacy can minimize the participation of the data owners in DaaS provision.
