Rapid joule heating improves vitrification based cryopreservation

open access: yesNature Communications, 2022
Lower concentrations of toxic cryoprotective agents require rapid and scalable rewarming techniques. Here, the authors report on a joule heating–based platform where samples are rapidly rewarmed by contact with a voltage pulsed electrical conductor and ...

Yeast Exoglycoproteins Produced Under NaCl-Stress Conditions as Efficient Cryoprotective Agents

open access: yesBiological Procedures Online, 1998
Six extracellular yeast glycoproteins were prepared from three yeast species in osmotic equilibrium and unequilibrium environments and used as non-penetrating cryoadditives. Glycoproteins secreted by the strain Dipodascus australiensis into growth medium

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

open access: yesAnimals, 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 ...

Preservation of bovine preantral follicle viability and ultra-structure after cooling and freezing of ovarian tissue [PDF]

open access: yes, 2008
Bovine preantral follicles within ovarian fragments were exposed and cryopreserved in absence or presence of 1.5 M glycerol (GLY), ethylene glycol (EG), propanediol (PROH) or dimethyl sulfoxide (DMSO), undergoing a previous cooling at 20 °C for 1 h ...
