Tight junction between endothelial cells: the interaction between nanoparticles and blood vessels
Beilstein Journal of Nanotechnology, 2016 Since nanoparticles are now widely applied as food additives, in cosmetics and other industries, especially in medical therapy and diagnosis, we ask here whether nanoparticles can cause several adverse effects to human health.

Human sperm displays rapid responses to diet
PLoS Biology, 2019 The global rise in obesity and steady decline in sperm quality are two alarming trends that have emerged during recent decades. In parallel, evidence from model organisms shows that paternal diet can affect offspring metabolic health in a process ...

Protein-carbohydrate interactions during fertilization [PDF]
, 1998 Interaction between gametes during fertilization is at least in part regulated by carbohydrate moieties of the zona pellucida (ZP) and carbohydrate binding proteins of the sperm surface. This review focuses on the protein-carbohydrate interactions during

FEBS Open Bio, EarlyView.In the blood–testis barrier, occludin is crucial for tight junctions. This study demonstrates that occludin‐targeting short peptides disrupt junction integrity, inducing immune cell infiltration, tumor necrosis factor‐α/interleukin‐6 secretion and mitochondrial dysfunction, ultimately triggering apoptosis.

Egg donors’ attitudes toward identifiability, offspring information, and genetic testing
Reproductive Biology and EndocrinologyBackground Research on egg donors’ perspectives regarding identifiability, donor-conceived offspring, and genetic testing remains limited, as most studies have focused on sperm donors.

Cellular Cargo Delivery: Toward Assisted Fertilization by Sperm-Carrying Micromotors.
Nano letters (Print), 2016 We present artificially motorized sperm cells-a novel type of hybrid micromotor, where customized microhelices serve as motors for transporting sperm cells with motion deficiencies to help them carry out their natural function.

Molecular and Cellular Endocrinology, 2020 Centrioles are eukaryotic subcellular structures that produce and regulate massive cytoskeleton superstructures. They form centrosomes and cilia, regulate new centriole formation, anchor cilia to the cell, and regulate cilia function. These basic centriolar functions are executed in sperm cells during their amplification from spermatogonial stem cells ...
