Environmental Drivers of Malignant Clonal Selection in Precancerous Lesion Evolution

Cell Proliferation, EarlyView.
ABSTRACT Somatic mutations accumulation and subsequent malignant clonal selection are the processes that lead to cancer. The intricacy includes exposure to carcinogens as well as the ways in which these exposures interact with genetic, polygenic, or epigenetic predispositions.

Importance of Estrus Expression Before Fixed-time AIon Conception Rates in Beef Cattle [PDF]

, 2015
Expression of estrus prior to fixed-time AI has been reported to strongly impact overall pregnancy success. Behavioral estrus is a visual indicator that a cow or heifer’s internal environment is prepared for breeding.

Decoding the Molecular Landscape of Prepubertal Oocyte Maturation: GTPBP4 as a Key Driver of In Vitro Developmental Competence

Cell Proliferation, EarlyView.
Transcriptional and translational characteristics during goat oocyte maturation and identification of key factors, including GTPBP4, for prepubertal goat oocyte maturation. ABSTRACT The intricate mechanisms driving oocyte maturation remain only partially understood, especially within the domains of domestic animal reproduction and translational ...

GPD1L‐Mediated Glycerophospholipid Metabolism Dysfunction in Women With Diminished Ovarian Reserve: Insights From Pseudotargeted Metabolomic Analysis of Follicular Fluid

Cell Proliferation, EarlyView.
Our study demonstrated the downregulation of GPD1L and its mediated glycerophospholipid metabolism dysfunction in patients with diminished ovarian reserve. Moreover, we verified that GPD1L knockdown leads to increased cell apoptosis and mitochondrial dysfunction of KGN cells, as well as impaired oocyte quality.

Timed Insemination vs. Modified Estrus Detection in Beef Heifers [PDF]

, 2017
Th e objective of this study was to compare a modified estrus detection and fixed time AI vs. no estrus detection and fixed time AI on subsequent pregnancy rates. Yearling heifers were estrus synchronized and AI at 72 ± 2 h after prostaglandin injection.

Fungal endometritis associated with embryonic loss in a maiden mare

Equine Veterinary Education, EarlyView.
Summary Fungal endometritis and placentitis have been reported as a rare but important cause of infertility in the mare. There are no reported clinical cases of fungal endometritis causing embryonic loss in the mare. This case report aims to highlight the potential of fungal endometritis as an aetiological agent in embryonic loss in the mare; an ...

In vitro antimicrobial activity of non‐traditional therapies for infectious endometritis in mares

Equine Veterinary Journal, EarlyView.
Abstract Background Endometritis is the leading cause of subfertility in horses, and it is a clinical problem where historically antibiotics have not always been used with prudent justification. Because of this, alternative therapies to treat endometritis are necessary for the rational use of antibiotics. Objectives To assess the in vitro antimicrobial

Pituitary Adenylate Cyclase-Activating Polypeptide (PACAP) Signaling in The Prefrontal Cortex Modulates Cued Fear Learning, But Not Spatial Working Memory, in Female Rats [PDF]

, 2018
A genetic polymorphism within the gene encoding the pituitary adenylate cyclase- activating polypeptide (PACAP) receptor type I (PAC1R) has recently been associated with hyper-reactivity to threat-related cues in women, but not men, with post-traumatic ...

Estrogen synthesized in the central nervous system enhances MC4R expression and reduces food intake

The FEBS Journal, EarlyView.
Estrogen is regulated by the rate‐limiting enzyme aromatase. This study examines how neuroestrogens, estrogen produced in the brain, regulate appetite through the hypothalamus. Using ovariectomized, aromatase knockout, and brain‐specific aromatase‐restored mice, the study found that neuroestrogens suppress appetite by influencing genes like Mc4r.
