Evaluating the effects of different methods of estrus synchronization in the agouti (Dasyprocta leporina)

Theriogenology Wild, 2023
There has been limited work done on estrus synchronization or induction in the Dasyprocta species. This experiment sought to apply three different methods of estrus synchronization to fifteen agoutis (Dasyprocta leporina) which were placed into three ...

The ecology of gestational growth in a wild cooperative mammal

Journal of Animal Ecology, EarlyView.
Using data from hundreds of wild pregnant meerkats, Thorley et al show that gestational growth varies widely, is shaped by nutrition but not social conditions, and improves pup survival without shortening telomeres. The fitness consequences and limited flexibility of prenatal growth likely enhance selection on early postnatal growth plasticity ...

Inseminations at Estrus Induced by Presynchronization Before Application of Synchronized Estrus and Ovulation [PDF]

Journal of Dairy Science, 2005
A controlled field study examined conception rates after 2 timed artificial insemination (TAI) breeding protocols conducted on 2 commercial dairy farms. Estrous cycles in postpartum lactating cows were presynchronized with 2 injections of PGF(2alpha) given 14 d apart (Pre-synch) and then, after 12 d, the standard Ovsynch protocol (injection of GnRH 7 d

Mapping the variability of in vivo rat uterine electrical properties throughout the oestrous cycle

Experimental Physiology, EarlyView.
Abstract After reaching sexual maturity, uterine function is driven by cyclical variations in hormone levels. The electrical and mechanical activity in the uterus varies during the menstrual cycle, contributing to essential functions such as sperm transport and shedding the menstrual lining.

Synchronization of breeding and its impact on genetic parameters and evaluation of female fertility traits

Journal of Dairy Science, 2023
: Achieving an acceptable level of fertility in herds is difficult for many dairy producers because identifying cows in estrus has become challenging owing to poor estrus expression, increased herd size, and lack of time and skilled labor for estrus ...

Effect of metformin on inflammation and bone damage in a rat model of medication‐related osteonecrosis of the jaw

European Journal of Oral Sciences, Volume 134, Issue 1, February 2026.
Abstract This study investigated how chronic metformin administration modulates the cellular profile and inflammatory markers in a zoledronic acid‐based rat model of medication‐related osteonecrosis of the jaw (MRONJ). Male Wistar rats were allocated to different treatments: (i) naïve, (ii) MRONJ (zoledronic acid, 0.2 mg/kg, i.v.
