Morphological Aspects in Corpus Luteum Formation in Mice

open access: yesScientific Papers Animal Science and Biotechnologies, 2023
Immediately after ovulation, in the follicular cavity, by multiplying and metaplasia of granulosa and internal sheath cells, a transient endocrine gland is formed, known as the corpus luteum (corpus luteum). Although in adult mice, ovulation occurs every

Biosynthesis of retinal in bovine corpus luteum

open access: yesJournal of Lipid Research, 1974
Bovine corpus luteum tissue was sliced and incubated with β-[15,15′-3H]carotene. The conversion of radioactive β-carotene into radioactive retinal was substantiated utilizing column chromatography, thin-layer chromatography, high-speed liquid ...

Review: Comparative of monitoring estrus cycle in livestock: Hormonal features and ultrasound

open access: yesJurnal Ilmu-Ilmu Peternakan, 2020
The estrus cycle is a period in which a female animal shows the ability to become pregnant, and this event will continue over some time. The estrus cycle has two different phases, the follicular phase characterized by the presence of graffian follicles ...

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 ...

Regulation of 3β-Hydroxysteroid Dehydrogenase/∆5-∆4 Isomerase: A Review [PDF]

open access: yes, 2013
This review focuses on the expression and regulation of 3β-hydroxysteroi ddehydrogenase/Δ5-Δ4 isomerase (3β-HSD), with emphasis on the porcine version. 3β-HSD is often associated with steroidogenesis, but its function in the metabolism of both steroids ...

A Microfiber‐Reinforced Janus Hydrogel E‐Skin With Recyclable Feature for Multimodal Sensing and Gender‐Specific Physiological Monitoring

open access: yesAdvanced Science, EarlyView.
Hydrogel‐based wearable electronics hold great promise for physiological monitoring in privacy‐sensitive regions. In this study, a polyurethane (PU) microfiber‐reinforced gelatin hydrogel e‐skin is developed, boasting multiple advantages such as ultra‐thinness, high toughness, and long‐term skin conformability.

Reconstruction, analysis and comparison of gene networks topology based on RNA-Seq data involved in reproductive and fertility complex traits. [PDF]

open access: yesمجله بیوتکنولوژی کشاورزی, 2019
Objective  In spite of the importance of fertility in different species, there has been little success dissecting the levels of OMICS. To better understand the molecular basis of fertility, we study transcriptome profiling of different tissues ...

Homozygous disruption of P450 side-chain cleavage (CYP11A1) is associated with prematurity, complete 46,XY sex reversal, and severe adrenal failure [PDF]

open access: yes, 2005
Disruption of the P450 side-chain cleavage cytochrome (P450scc) enzyme due to deleterious mutations of the CYP11A1 gene is thought to be incompatible with fetal survival because of impaired progesterone production by the fetoplacental unit.
