A non‐hormonal reversible contraceptive targeting GSK3α, a protein kinase, essential for epididymal sperm maturation

open access: yesAndrology, EarlyView.
Abstract Background and objectives Epididymal transit renders key competence to mammalian spermatozoa for fertilizing eggs. Generally, the two paralogs of glycogen synthase kinase 3, GSK3α and GSK3β, functionally overlap except in testis and sperm. We showed that GSK3α is essential for epididymal sperm maturation and fertilization.

Proteomic profiling of porcine seminal extracellular vesicles reveals potential in vivo fertility biomarkers

open access: yesAndrology, EarlyView.
Abstract Background Predicting male fertility in farm animals remains a challenge. Seminal plasma (SP) contains a high amount of heterogeneous seminal extracellular vesicles (sEVs), believed involved in reproductive processes and maybe key to understanding male fertility.

Phospholipids oxidation and foaming enhancement of egg albumen

open access: yes, 2018
The oxidative stability of egg and soy lecithin in emulsions was evaluated with two transition metal ions, cupric and ferric ions, at two concentrations (50 and 500 μM). The effect of pH on lipid oxidation was also examined under these two concentrations for each ion.

Morphological variations of the ovarian follicles and oviduct of commercial Lohmann Brown and indigenous Potchefstroom Koekoek breeds

open access: yesActa Zoologica, EarlyView.
Abstract Egg laying begins with the orderly development of follicles in the chicken ovaries and transportation through the oviduct with deposition of nutrients until the eggs are produced. However, the ovarian follicles and oviduct morphology of Lohmann Brown and Potchefstroom Koekoek laying hens have not yet been studied.

Avian embryonic development in hyperdynamic environments [PDF]

open access: yes
Embryos which developed for 24 hours in the oviduct of hens maintained at 2 G and which were subsequently incubated at Earth gravity had a 14% reduction in hatchability.

Matrix metalloproteinase inhibition protects against junctophilin‐2 proteolysis during doxorubicin‐induced cardiotoxicity

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Treatment of cancer patients with anthracyclines is known to cause dose‐dependent cardiotoxicity through several mechanisms including enhanced oxidative stress, ultimately resulting in defective excitation–contraction coupling.
