Pro-inflammatory Cytokines and Their Receptors: Expression and Regulation in the Uterine Endometrium during the Estrous Cycle in Pigs

Journal of Animal Reproduction and Biotechnology, 2016
Pro-inflammatory cytokines, interleukin-1β (IL1B), IL6, and tumor necrosis factor-alpha (TNF), are known to play important roles in regulating the endometrial function in the uterus during the estrous cycle and pregnancy in several species.

Characterization of the Estrous Cycle in Octodon degus [PDF]

Biology of Reproduction, 2010
We characterized the reproductive cycle of Octodon degus to determine whether reproductive maturation is spontaneous in juveniles and if ovarian cyclicity and luteal function are spontaneous in adults. Laboratory-reared prepubertal and adult females were monitored for vaginal patency and increased wheel-running.

A simple mathematical model of the bovine estrous cycle: Follicle development and endocrine interactions

, 2010
Bovine fertility is the subject of extensive research in animal sciences, especially because fertility of dairy cows has declined during the last decades.

Follicular Dynamics during Estrous Cycle of Pubertal, Mature and Postpartum Crossbred (Nili Ravi × Jianghan) Buffaloes

Animals, 2022
The follicular dynamics is used as a reliable indicator for reproductive management in livestock. However, the follicular dynamics (follicle wave emergence, estrus cycle length, diameter of dominant follicle, follicular growth and atretic phases) during ...

Estrous behavior in dairy cows: identification of underlying mechanisms and gene functions

, 2010
Selection in dairy cattle for a higher milk yield has coincided with declined fertility. One of the factors is reduced expression of estrous behavior. Changes in systems that regulate the estrous behavior could be manifested by altered gene expression ...

Influence of Estrous Cycle Hormonal Fluctuations and Gonadal Hormones on Neurogenesis in the Subventricular Zone of Adult Mice

مجله دانشگاه علوم پزشکی گرگان, 2022
Background and Objective: Neurogenesis is the process through which neurons are generated from neural stem cells. This process has been shown to occur in special zones of the adult brain including the subventricular zone (SVZ) of the lateral ventricles ...

Gene expression patterns in four brain areas associate with quantitative measure of estrous behavior in dairy cows

BMC Genomics, 2011
Background The decline noticed in several fertility traits of dairy cattle over the past few decades is of major concern. Understanding of the genomic factors underlying fertility, which could have potential applications to improve fertility, is very ...
