Substance P regulates puberty onset and fertility in the female mouse [PDF]

open access: yes, 2015
Puberty is a tightly regulated process that leads to reproductive capacity. Kiss1 neurons are crucial in this process by stimulating GnRH, yet how Kiss1 neurons are regulated remains unknown. Substance P (SP), an important neuropeptide in pain perception,

Pharmacokinetics of Two Formulations of Altrenogest Administered to Mares

open access: yesDrug Testing and Analysis, EarlyView.
Pharmacokinetics of altrenogest in mares to determine expected concentrations of plasma altrenogest associated with oral and intramuscular administration. Quantification of altrenogest in mares is of increasing importance with prohibited formulations and restrictions on administration.

Analysis of the hypothalamic oxytocin system and oxytocin receptor‐expressing astrocytes in a mouse model of Prader–Willi syndrome

open access: yesJournal of Neuroendocrinology, Volume 34, Issue 12, December 2022., 2022
If and how genetic disorders such as Prader‐Willi (PWS) or Schaaf‐Yang (SYS) syndromes affect oxytocinergic signaling is not well studied. In this study we used our established and well‐characterised Magel2 KO mouse model and analysed the number of oxytocin (OT) cells and OT receptor‐expressing (OTR) astrocytes.

Pemanfaatan Electronic Nose sebagai Sensor Kimiawi Urin Guna Melacak Birahi Sapi (ELECTRONIC NOSE AS URINARY CHEMICAL SENSOR FOR DETERMINING ESTROUS PHASE IN CATTLE)

open access: yesJurnal Veteriner, 2017
The timing of artificial insemination relies largely on behavioral observation of estrus. The problemfaced is that not all cattle shows signs of estrus significantly, which affect the accuracy of insemination,and therefore,the success rate of Artificial ...

Daily lying behavior of lactating Holstein cows during an estrus synchronization protocol and its associations with fertility.

open access: yesJournal of Dairy Science, 2017
Objectives were to quantify lying behavior (LB) during an estradiol and progesterone-based synchronization protocol, to assess risk factors for ovulation, pregnancy per AI (P/AI), and degree of behavioral change at estrus, and to investigate the ...

Estimates of correlation between estrus behavior and estradiol concentrations during estrus [PDF]

open access: yes, 2021
Estrus traits have economic value in dairy production systems and can potentially be incorporated into genomic selection. Three studies were performed to further understand selection responses. Study one and two explored the relationship between rump touches and number of steps during estrus.

Analysis pipeline to quantify uterine gland structural variations

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Technical advances in whole tissue imaging and clearing have allowed 3D reconstruction of exocrine uterine glands deep‐seated in the endometrium. However, there are limited gland structure analysis platforms to analyze these imaging data sets. Here, we present a pipeline for segmenting and analyzing uterine gland shape.

Social effects on behaviorally-scored and pedometer-detected estrus in beef cattle

open access: yesThe Journal of Reproduction and Development
The number of cows in estrus often influences estrus behavior; however, the effects of social order are not well documented. This study examined the effects of social order on the expression of behaviorally-scored and pedometer-detected estrus, combined ...

Differences in Microbial Community Composition between Uterine Horns Ipsilateral and Contralateral to the Corpus Luteum in Beef Cows on Day 15 of the Estrous Cycle

open access: yesMicroorganisms, 2023
This study evaluated differences in uterine microbiota composition between uterine horns ipsilateral and contralateral to the corpus luteum of beef cows on day 15 of the estrous cycle.
