Capacitation of bovine sperm by heparin.
Biology of Reproduction, 1988 Capacitation of bovine sperm was evaluated by determining the ability of sperm to fertilize bovine oocytes in vitro and to undergo an acrosome reaction upon exposure to lysophosphatidylcholine (LC).

Cryopreservation of Pike Perch Sperm in Hatchery Conditions [PDF]
, 2008 Experiments were carried out on pike perch (Sander lucioperca L.) to find a method for stripping sperm without contamination by urine, to determine sperm concentration, and to fertilize large batches of eggs with cryopreserved sperm.

Sperm Depletion and Mating Behavior in the Parasitoid Wasp \u3ci\u3eSpalangia Cameroni\u3c/i\u3e (Hymenoptera: Pteromalidae) [PDF]
, 2018 Mating behavior was examined in the parasitoid wasp Spalangia cameroni. Males attempted copulation with both virgins and already mated females. Males attempted copulation regardless of whether they still had sperm. Already mated females rejected attempts

Use of sperm DNA fragmentation testing and testicular sperm for intracytoplasmic sperm injection [PDF]
Translational Andrology and Urology, 2017 Dr. Ahmad, in his well-written commentary (1), shared his viewpoints about the utility of sperm DNA fragmentation (SDF) testing on each clinical scenario proposed in the practice recommendations by Agarwal et al . (2). He highlighted the pitfalls of relying on quantitative semen parameters in current practice and the need for a more reliable ...

Post‐Translational Modifications in Cilia and Ciliopathies
Advanced Science, EarlyView.This review synthesizes current understanding of post‐translational modifications (PTMs) in ciliary proteins and emphasizes their roles in ciliary formation, homeostasis, and signaling. This review also discusses the implication of PTM dysregulation in ciliopathies and explores therapeutic strategies targeting PTM‐modifying enzymes.

Advanced Science, EarlyView.High QSOX2 enhances stemness, drug resistance, and metastasis of ESCC cells. QSOX2‐mediated disulfide bond modification activates mTOR/c‐Myc signaling. CAFs‐secreted IGF‐1 drives mTOR/c‐Myc/QSOX2 positive feedback loop. Combining Ebselen, rapamycin, and cisplatin induces tumor dormancy in mice.

Journal of Reproduction and Fertility, 1984 The objective of this study was to develop a relatively simple test to evaluate the functional integrity of the membranes of human spermatozoa. As in some other species, human spermatozoa 'swell' under hypo-osmotic conditions due to the influx of water ...
