A review of the impact of micro‐ and nanoplastics on female reproduction: What we know and gaps in knowledge

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Micro‐and nanoplastics (MNPs) are breakdown products of plastics, and humans are exposed to these particles through air, water, food, and soil. There is a growing concern that human exposure to MNPs negatively impacts health. In this review we will discuss the potential health impact of MNPs on ovarian function and the hypothalamic–pituitary ...

Different dendritic domains of the GnRH neuron underlie the pulse and surge modes of GnRH secretion in female mice

eLife, 2020
The gonadotropin-releasing hormone (GnRH) neurons exhibit pulse and surge modes of activity to control fertility. They also exhibit an unusual bipolar morphology comprised of a classical soma-proximal dendritic zone and an elongated secretory process ...

Estrous behavior in dairy cows: identification of underlying mechanisms and gene functions [PDF]

, 2010
Selection in dairy cattle for a higher milk yield has coincided with declined fertility. One of the factors is reduced expression of estrous behavior. Changes in systems that regulate the estrous behavior could be manifested by altered gene expression ...

Endometrial Stromal Cell Senescence: A Non‐Negligible Factor in Recurrent Pregnancy Loss

iMetaMed, EarlyView.
As populations age, links between female reproductive aging and infertility are increasingly evident. Cellular senescence, characterized by near‐irreversible cell‐cycle arrest and accumulation of damage, can impair tissue function. In the endometrium, aberrant senescence of endometrial stromal cells (EnSCs) may compromise receptivity, hinder embryo ...

Role of Acid‐Sensing Ion Channels 1a in the Regulation of Obesity and the Gut Microbiota

Obesity, EarlyView.
ABSTRACT Objective Acid‐sensing ion channels are proton‐activated ion channels predominantly found in the nervous system. They are well known to affect metabolic and neurological health, yet their role in obesity and gut physiology remains unclear. This study investigates how systemic deletion of Asic1a influences obesity, metabolic, and gut‐based ...
