Potential Neuroendocrine Disruption by Benzodiazepines and Its Impact on Male Fertility

Journal of Applied Toxicology, EarlyView.
ABSTRACT Neuroactive substances have emerged as potent endocrine disruptors affecting male reproductive health through central and peripheral mechanisms. Among these, benzodiazepines, which are widely used for the management of anxiety, insomnia, epilepsy, and neuromuscular disorders, are known as GABA A (gamma‐aminobutyric acid type A) receptor ...

Fern sperm release

, 2014
Fern spores germinate into haploid fern gametophytes; small plants only a few millimeters in diameter. These gametophytes produce sperm by mitosis in small sacs called antheridia. When placed in water, the antheridium opens up, and the sperm are released.

Low‐Level Human Epididymis Protein 4 in Seminal Plasma Is an Independent Risk Factor for Poor Semen Liquefaction: A Case Control Study

Journal of Clinical Laboratory Analysis, EarlyView.
Our work identifies a novel and significant association between low seminal levels of Human Epididymis Protein 4 (HE4) and the clinical condition of poor semen liquefaction, a common cause of male infertility. The findings are statistically robust, clinically relevant, and provide a foundational basis for future research into the mechanism by which HE4

Adaptive Immunity in Marsupials

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
Comparison of the marsupial and eutherian adaptive immune systems. ABSTRACT Marsupials diverged from eutherian mammals 125–160 million years ago. Although evolutionarily distinct, both groups of mammals can produce complex adaptive immune responses to antigens with several key differences.

Noncanonical Nucleotides in the Genome Around the Maternal‐Zygotic Transition

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In this paper, Kazzazi et al. provide a comprehensive review of the dynamics of nonconventional nucleotides in the genome during early developmental stages, hypothesizing a potential role for these nucleotides in the activation of the zygotic genome. ABSTRACT From the very moment of fertilization and throughout development, the cells of animal embryos ...
