- Journal of reproduction and fertility
- 1 September 1978
A technique was developed to obtain enriched populations of large numbers of primary spermatacytes (70--81%) and of spermatids (75%) from immature rat testes (21--23 and 38 days old respectively) in… Expand
Changes in calmodulin compartmentalization throughout capacitation and acrosome reaction in guinea pig spermatozoa
Calmodulin has been postulated as a mediator in the calcium‐dependent processes that culminate in the acrosome reaction. Changes in calmodulin compartmentalization as a consequence of the increased… Expand
Effects of quercetin on rat testis aerobic glycolysis.

- 1 November 1995
Lactate production by testicular fragments and isolated germinal cells at various stages of spermatogenesis was studied in aerobic and anerobic conditions. Several ATPase inhibitors were used to… Expand
Calmodulin binding proteins in the membrane vesicles released during the acrosome reaction and in the perinuclear material in isolated acrosome reacted sperm heads.

Calmodulin has been suggested as the Ca(2+)-mediator in diverse cellular functions via its interaction with a number of proteins in a calcium-dependent manner. Its participation in the acrosome… Expand

In contrast with the transient pre‐replicative increase in calmodulin (CaM) level observed in proliferative activated cells, postnatal development of rat testis was paralleled by 3 specific rises in… Expand
Changes in cyclin B localisation during pig oocyte in vitro maturation.

The localisation of cyclin B throughout in vitro maturation of pig oocytes was determined by indirect immunofluorescence using a monoclonal antibody specific for an epitope of the human cyclin B.… Expand
Inbreeding depression and a poor start in life
- R. Trejo
- Biology
- 2018
Inbreeding is a widespread phenomenon that can decrease fitness.
Inbreeding depression occurs because matings between relatives
lead to an increase in homozygosity. Inbreeding is a pervasive
force… Expand
