A Comparison of the Fertile Phase As Determined by the Clearplan Easy Fertility Monitor™ and Self-Assessment of Cervical Mucus [PDF]

open access: yes, 2004
The purpose of this study was to compare the fertile phase of the menstrual cycle as determined by the Clearplan Easy Fertility Monitor (CPEFM) with self-monitoring of cervical mucus.

Hepatic KLF9 Deficiency Inhibits Dehydroepiandrosterone (DHEA)‐Induced Polycystic Ovary Syndrome via Liver‐Ovary Axis

open access: yesAdvanced Science, EarlyView.
The study shows that liver is a previously unrecognized extraovarian organ that plays a key role about androgen homeostasis in the development of DHEA‐induced PCOS. DHEA is the most common precursor of active androgen, such as DHT, and KLF9 is required for the conversion of DHEA to DHT and hepatic KLF9 might be a potential therapeutic target for PCOS ...

Use of Urinary Pregnanediol 3-glucuronide to Confirm Ovulation [PDF]

open access: yes, 2013
Objective Urinary hormonal markers may assist in increasing the efficacy of Fertility Awareness Based Methods (FABM). This study uses urinary pregnanediol-3a-glucuronide (PDG) testing to more accurately identify the infertile phase of the menstrual cycle

5‐Hydroxymethylcytosine Dynamics Reveals Coordinated Reprogramming of Parental Genomes and X Chromosome Dosage Balance in Mouse SCNT Embryos

open access: yesAdvanced Science, EarlyView.
Genome‐wide, high‐resolution profiling of hydroxymethylation in mouse SCNT embryos reveals a transient, allele‐symmetric 5hmC reprogramming pattern distinct from natural embryos, with X‐chromosomes and imprinting control regions resistant to proper remodeling.

Economic consequences of reproductive performance in dairy cattle [PDF]

open access: yes, 2010
The net economic value of reproductive efficiency in dairy cattle was estimated using a stochastic dynamic simulation model. The objective was to compare the economic consequences of reproductive performance scenarios (“average” and “poor”) of a cow ...

Designing Memristive Materials for Artificial Dynamic Intelligence

open access: yesAdvanced Intelligent Discovery, EarlyView.
Key characteristics required of memristors for realizing next‐generation computing, along with modeling approaches employed to analyze their underlying mechanisms. These modeling techniques span from the atomic scale to the array scale and cover temporal scales ranging from picoseconds to microseconds. Hardware architectures inspired by neural networks

Disruption of ovarian function and induction of apoptosis in female mice by Brefeldin A: Mechanistic insights into reproductive toxicity

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Brefeldin A (BFA) significantly inhibits oocyte release and induces apoptosis in ovarian granulosa cells by disrupting follicular development. It downregulates proliferation‐associated genes, reduces SIRT1/SIRT6 proteins, and upregulates cell cycle inhibitors P21 and P16. Additionally, BFA impairs estrogen synthesis and affects ovarian function through

THE EFFECT OF HORMONAL TREATMENTS ON THE PREGNANCY RATES OF MARES

open access: yesSiberian Journal of Life Sciences and Agriculture, 2022
To determine the effect of hormonal drugs on the pregnancy rates of mares, authors analyzed this indicator in natural (n=303) and stimulated cycles (n=170).

Expanded application to plant reproductive tissues of a branched DNA probe‐based in situ hybridization method

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Detecting clear tissue‐ and organ‐specific patterns of gene expression is key to understanding the genetic mechanisms that control plant development. In situ hybridization (ISH) of mRNA is one of the most precise, yet most challenging approaches to gene expression assays.

Kisspeptin-neuron control of LH pulsatility and ovulation

open access: yesFrontiers in Endocrinology, 2022
Feedback from oestradiol (E2) plays a critical role in the regulation of major events in the physiological menstrual cycle including the release of gonadotrophins to stimulate follicular growth, and the mid-cycle luteinising hormone (LH) surge that leads
