Exploration of the dynamic regulation of the hypothalamic-pituitary-ovarian axis during the estrous cycle

open access: yesJournal of Ovarian Research
Background One of the most challenging issues in current assisted reproductive technology is how to optimally counsel and treat patients with poor ovarian response (POR). However, current research predominantly emphasized the ovarian local changes during

The pyruvate generator is a common phenomenon in mitochondria from different rat and mouse brain regions

open access: yesFEBS Letters, EarlyView.
The pyruvate generator, which causes activation of respiration by extra‐mitochondrial Ca2+, is also present and functional in rat brainstem mitochondria, as it is in other brain regions. This finding is confirmed by experiments with a fully reconstituted malate–aspartate shuttle (MAS).

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome

open access: yesFEBS Letters, EarlyView.
This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

The impact of pre-pregnancy overweight/obesity on the birth weight of offspring born from women with polycystic ovarian syndrome

open access: yesBMC Pregnancy and Childbirth
Objectives The purpose of our study is to explore whether polycystic ovary syndrome (PCOS) has an independent impact on the neonatal birth weight (BW), and whether pre-pregnancy overweight/obesity plays a mediating role on the association between PCOS ...

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Kenya: Communities support adolescent reproductive health education

open access: yes, 2003
Young people in Kenya have limited knowledge of reproductive health (RH) and face many challenges in their transition to adulthood. Chief among these challenges is the high prevalence of HIV/AIDS among adults and its increasing incidence among rural ...

Ubiquitination of secretory granules promotes their crinophagic degradation in Drosophila

open access: yesFEBS Letters, EarlyView.
Ubiquitination of secretory granules in Drosophila larval salivary glands is a critical molecular trigger for crinophagy, the lysosomal degradation of unreleased, or low‐quality granules. The E3 ubiquitin ligase Cnot4 is recruited to the surface of secretory granules to induce crinophagy.

Mothers and sisters: educators of sexual health information among young Niue women born in New Zealand

open access: yes, 2019
Background: For many Pacific youth in New Zealand, discussing sexual health topics with their parents or families remains a highly sensitive subject that is uncomfortable and culturally challenging.

The threshold of estradiol level for fresh embryo transfer differs between blastocyst and cleavage‐stage embryo

open access: yesActa Obstetricia et Gynecologica Scandinavica
Introduction Ovarian stimulation can cause supraphysiological estradiol levels and adverse effects on endometrial receptivity. Since patients could undergo cleavage or blastocyst stage embryo transfer, the threshold value of peak estradiol level for each
