Carbachol increases intracellular free calcium concentrations in human granulosa-lutein cells [PDF]

open access: yes, 1992
We investigated whether the stimulation of human granulosa-lutein cells with muscarinic and nicotinic receptor agonists can cause increases in intracellular free calcium (Ca2+), using Fura-2 microfluorimetry.

Does synchronising follicular wave emergence improve outcomes in non‐superstimulated donor cattle undergoing ovum pick‐up (OPU) for in vitro embryo production?

open access: yesAustralian Veterinary Journal, EarlyView.
In vitro embryo production (IVEP) is now a widely commercialised assisted reproductive technology used in cattle reproduction. The use of follicle‐stimulating hormone (FSH) to superstimulate donor cattle prior to ovum pick‐up (OPU) is generally regarded as an effective strategy to improve oocyte quality, developmental competence and increase embryo ...

Angiogenesis in the corpus luteum

open access: yesReproductive Biology and Endocrinology, 2003
The corpus luteum (CL) is a site of intense angiogenesis. Within a short period, this is followed either by controlled regression of the microvascular tree in the non-fertile cycle, or maintenance and stabilisation of the new vasculature a conceptual ...

Oocytes Population and Development Competence of Bali Cattle Embryo In Vitro with Different Ovarian Reproductive Statuses

open access: yesTropical Animal Science Journal, 2022
The present study aims to determine the potential of Bali cattle ovaries as sources of oocytes for in vitro embryo production based on different ovarian reproductive statuses. The ovaries were grouped into 4 categories: ovaries with no corpus luteum and

Comparison of synchronized-ovulation protocols and traditional synchronized-estrys programs using prostaglandin F2(alpha) [PDF]

open access: yes, 1995
Five treatments were developed to compare a new synchronized ovulation protocol, which programs follicular development with the regression of the corpus luteum, and traditional prostaglandin protocols that only control the regression of the corpus ...

Effects of Prepartum Supplementation and Yeast Fermentation Products on the Progesterone‐Modulated Transfer of Passive Immunity in Bos indicus Cows

open access: yesJournal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Inadequate colostrum intake increases risks of calf morbidity and mortality. This study investigated the effects of prepartum and early postpartum supplementation and yeast fermentation products on late‐pregnant Bos indicus cows, and the role of progesterone in mediating passive immunity transfer.
