Optimization and verification of high‐fat diet formulation for establishing a rat model of obesity‐related precocious puberty

Animal Models and Experimental Medicine, EarlyView.
We identified 45% HFD as the optimal formulation to establish a juvenile rat model of obesity‐related precocious puberty. It elicits robust phenotypic (early vaginal opening, obesity), histological (advanced ovarian development), and endocrine (elevated HPG axis hormones) alterations, with leptin‐mediated GnRH secretion as a core mechanistic driver ...

ESTRUS SYNCHRONIZATION WITH MEDROXYPROGESTERONE ACETATE IMPREGNATED SPONGES IN GOATS (CAPRA HIRCUS) [PDF]

Pakistan Veterinary Journal, 2009
An experiment was performed to synchronize estrus in goats by locally prepared progesterone-impregnated sponges and to determine the time of onset and duration of estrus alongwith subsequent fertility rate.

Capturing temperature changes on the ocular surface along with estrus and ovulation using infrared thermography in Japanese Black cows

The Journal of Reproduction and Development, 2023
Pre-ovulatory follicles are cooler than the neighboring reproductive organs in cows. Thus, measuring the temperature of reproductive organs could be a useful method for predicting estrus and ovulation in cows, and the establishment of a non-invasive ...

Unraveling ovarian histology: The key morphological aspects that spur the development of the Fossa ovarii in equine

The Anatomical Record, EarlyView.
Abstract The equine ovary exhibits unique structural and developmental features that distinguish it from those of other domestic species, including the presence of an ovulation fossa and an inversion of cortical and medullary layers. This study aimed to investigate the morphostructural development of the equine fetal ovary, with particular emphasis on ...

Effect of Aegle marmelos and Murraya koenigii in treatment of delayed pubertal buffaloes heifers [PDF]

Veterinary World, 2016
Aim: This study aims to study the estrus induction, ovulation, and conception rate of delayed puberty in buffaloes heifers by feeding a herbal plants Aegle marmelos (bael/bili/bhel leaf) and Murraya koenigii (Curry leaf). Materials and Methods: Totally,

Gonadotropin-Releasing Hormone Increased Pregnancy in Suckled Beef Cows Not Detected in Estrus and Subjected to a Split-Time Artificial Insemination Program

, 2018
Estrus-synchronization programs allow insemination of all females in a herd at one fixed time on the first day of the breeding season. Inseminating cows after they have expressed estrus increases pregnancy rate (PR) compared with cows that do not display

Dietary Glutamine Supplementation Alleviated Rumen Epithelium Oxidative Damage and Apoptosis Induced by Feed Restriction via Maintaining Mitochondrial Homeostasis in Female Yaks

Animal Research and One Health, EarlyView.
Dietary glutamine (Gln) supplementation increased the ATP levels and promoted cell proliferation in the rumen epithelium of feed‐restricted yaks. Besides, Gln inhibited ROS accumulation and reduced oxidative damage and apoptosis in the rumen epithelium of feed‐restricted yaks.

Expression of mutant TIE2 p.L914F during mouse development causes embryonic lethality and defects in vascular remodeling

Developmental Dynamics, EarlyView.
Abstract Background Sporadic venous malformation (VM) is associated with the hyperactivating p.L914F mutation in TIE2, a receptor tyrosine kinase essential for vascular development. This mutation is not found in hereditary VM, suggesting incompatibility with life when expressed during early vascular development.

Reduced Oligodendrocyte Density and Axonal Caliber Associated With Mitochondrial Alterations in the White Matter of Chronically‐Starved Mice

International Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Anorexia nervosa (AN) is a severe eating disorder associated with extreme weight loss, hyperactivity, and amenorrhea. Neuroimaging studies revealed brain atrophy and disruption of white matter integrity in the corpus callosum (CC) of patients with AN. However, the underlying pathophysiological mechanisms remain unclear.

The effect of salt-free - salt diet on the reproductive performance of Ile de France ewes [PDF]

Bulgarian Journal of Veterinary Medicine, 2019
The aim of the present study was to establish the effect of salt-free - salt diet (SFSD) on the size of antral follicles during salt consumption, the duration of controlled breeding campaign and the ferti¬lities of ewes from the Ile de France breed.
