EFFECT OF DIFFERENT CRYOPROTECTIVE AGENTS ON SKIM MILK AND DIMITROPOULUS EXTENDER FOR STALLION SEMEN CRYOPRESERVATION

Journal of the Indonesian Tropical Animal Agriculture, 2014
s to assess different CPAs on stallion semen cryopreservation. Skim milk (SM) and Dimitropoulos(DV) were the extenders used in this study; each was added by glycerol (Gly), combination of ethyleneglycol-glycerol (EG+Gly) or dimethilformamide (DMF).

The Role of Aquaporin 7 in the Movement of Water and Cryoprotectants in Bovine In Vitro Matured Oocytes

Animals, 2022
Aquaglyceroporins are known as channel proteins, and are able to transport water and small neutral solutes. In this study, we evaluate the effect of exposure of in vitro matured bovine oocytes to hyperosmotic solutions containing ethylene glycol (EG ...

Optimizing Cryopreservation: The Effect of MitoTEMPO and Glycerol Ratios on Ram Semen Quality After Freezing and Thawing. [PDF]

Vet Med Sci
After the experimental groups were formed in the pooled semen, they were cooled, frozen and stored in liquid nitrogen for 24 h. Then, motility and kinematic parameters were examined by phase contrast microscopy. Spermatozoon DNA integrity, MMP, Acrosomal damage and live spermatozoon ratio were analysed with a flow cytometer.

An Ultrapotent, Ultraeconomical, Antifreeze Polypeptide

Advanced Materials, EarlyView.
Simple and inexpensive polypeptides composed of random copolymers of alanine and glutamic acid are effective antifreezes for applications in foods and biomedicine. The polypeptides, inspired by natural extremophile proteins, inhibit the growth of large ice crystals and prevent damage to sensitive biologics.

An Allele of Glutamate Formiminotransferase Triggers 5‐Methyl‐Tetrahydrofolate‐to‐MeFox Conversion and Facilitates Folate Biofortification in Maize

Advanced Science, EarlyView.
This work demonstrates the distinct roles of the glutamate formiminotransferase (GFT) enzyme in plants. The GFT triggers the conversion of 5‐methyl‐tetrahydrofolate to MeFox in plants, a process distinct from its role as a formiminotransferase in mammals.
