Emerging roles for integrated stress response signaling in homeostasis

open access: yesThe FEBS Journal, EarlyView.
Integrated stress response (ISR), an evolutionarily conserved eukaryotic stress‐adaptive program in eukaryotes, has also been implicated in homeostatic functions. This review covers a broad body of literature and presents several homeostatic functions of ISR in the absence of stress: (a) developmental processes (morphogenesis, differentiation, aging), (

Serum Metabolomic Analysis of Synchronous Estrus in Yaks Based on UPLC-Q-TOF MS Technology

open access: yesAnimals
The yak is a unique species of livestock found in the Qinghai-Tibet Plateau and its surrounding areas. Due to factors such as late sexual maturity and a low rate of estrus, its reproductive efficiency is relatively low.

Estradiol, Progesterone, and Transforming Growth Factor α Regulate Insulin-Like Growth Factor Binding Protein-3 (IGFBP3) Expression in Mouse Endometrial Cells [PDF]

open access: yes, 2009
Insulin-like growth factor 1 (IGF1) Is Involved in the proliferation of mouse and rat endometrial cells in a paracrine or autocrine manner. Insulin-like growth factor binding protein-3 (IGFBP3) modulates actions of IGFs directly or indirectly.

Genetic Relationships Among Resilience, Fertility and Milk Production Traits in Crossbred Dairy Cows Performing in Sub‐Saharan Africa

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Change in climate over the past years and its impact on the environment have necessitated the inclusion of resilience traits in the breeding objectives of dairy cattle. However, the relationship between resilience and other traits of economic importance in dairy production is currently not well known. This study examined the genetic parameters

Suppression of estrus in cats with melatonin implants

open access: yesTheriogenology, 2009
The objective of this study was to assess the efficacy of a subcutaneous melatonin implant to suppress estrus in queens (felis catus). The hypothesis was that this implant would temporarily and reversibly suppress estrus in queens without producing any clinically detectable side effects.

Evaluation of Level of Milk Potential on Nutrient Balance in 2- and 4- Year- Old May- Calving Range Cows Grazing Sandhills Upland Range [PDF]

open access: yes, 2020
A modeling study evaluated the effects of milk production level on nutrient balance in May- calving cows grazing Sandhills upland range during the breeding season. Forage quality of upland range peaks in June and steadily declines in July until November.

Neuroendocrine mechanisms responsible for elevated gonadotrophin‐releasing hormone and luteinising hormone pulses in polycystic ovary syndrome

open access: yesJournal of Neuroendocrinology, EarlyView.
Abstract Polycystic ovary syndrome (PCOS) is the leading cause of anovulatory infertility in premenopausal individuals with ovaries worldwide. Despite the diagnostic features of anovulation, ovarian cysts, and hyperandrogenemia, which indicate that ovary dysfunction is the cause of the syndrome, changes in central neuroendocrine circuits are a ...
