Surubim-do-Paraíba oocytes viability after being exposed to different cryoprotectants

Effect of different types of cryoprotectants on developmental capacity of vitrified-thawed immature buffalo oocytes

Studies were conducted to compare viability of immature buffalo oocytes vitrified in different types of cryoprotectants on the post-thaw morphological appearance, the in vitro maturation and developmental competence of buffalo oocytes. The vitrification solution (VS) consisted of Dulbecco’s phosphate buffered saline (DPBS) supplemented with 0.5 M sucrose, 0.4% bovine serum albumin (BSA) and dif...

Chromosome Abnormalities and Viability of Vitrified Eight-Cell Mouse Embryos at Presence of Two Different Cryoprotectants at Different Storage Durations

OBJECTIVE Experiments were conducted to find the differences between post-thaw viability and chromosome aberrations in eight-cell mouse embryos at presence of dimethyl sulfoxide (DMSO) and 1, 2-propanediol (PROH) as croprotectants in different storage durations. MATERIALS AND METHODS In this case-control study, a total number of 720 mouse embryos from about 250 NMRI mice were vitrified with 3...

Do people become healthier after being promoted?

This paper examines the hypothesis that greater job status makes a person healthier. It begins by successfully replicating the well-known cross-section association between health and job seniority. Then, however, it turns to longitudinal patterns. Worryingly for the hypothesis, the data-on a large sample of randomly selected British workers through time-suggest that people who start with good h...

Viability of equine articular chondrocytes in alginate beads exposed to different oxygen tensions.

Ischaemia and reperfusion are suspected to alter chondrocyte metabolism. Here, we studied the effects of three oxygen (O2) tensions on the viability of equine articular chondrocytes isolated from the cartilage of the distal interphalangeal joint of horses. Chondrocytes were cultured in alginate beads under 1%, 5% or 21% gas phase O2 concentration for 14 days, cellular growth kinetics were measu...
