Interfacial engineering of polymer-MOF composite by in situ vitrification
, 2020 Non-stoichoimetric crystalline ZIF-62 was used as the filler for a 6FDA-DAM polyimide-based composite membrane. In situ melting and vitrification of ZIF-62 was then performed, to yield the ZIF-62 glass phase (agZIF-62), within the polymer matrix.

Vitrification of Human Germinal Vesicle Oocytes: before or after In Vitro Maturation? [PDF]
International Journal of Fertility and Sterility, 2017 Background The use of immature oocytes derived from stimulated cycles could be of great importance, particularly for urgent fertility preservation cases. The current study aimed to determine whether in vitro maturation (IVM) was more successful before

FEBS Letters, EarlyView.Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

Cryopreservation of rye protoplasts by vitrification [PDF]
Cryobiology, 1989 A procedure has been developed for the vitrification of mesophyll protoplasts isolated from leaves of nonacclimated (NA) and cold-acclimated (ACC) winter rye seedlings (Secale cereale L. cv Puma). The procedure involves (a) equilibration (loading) of the protoplasts with an intermediate concentration (1.5, 1.75, or 2.0 molar) of ethylene glycol (EG) at
