A monoclonal antibody, designated mAb P86/5, was generated by immunization of female Balb/c mice with a membrane vesicle fraction composed of the outer acrosomal membrane and plasma membrane (PM-OAM). As determined by fluorescence microscopy and electron microscopy P86/5 recognizes a sperm plasma membrane antigen that is restricted to the sperm head ...

Notoginsenoside R1 protects boar sperm during liquid storage at 17 °C.
Reproduction in domestic animals = Zuchthygiene, 2020Reactive oxygen species (ROS) damage mammalian sperm during liquid storage. Notoginsenoside R1 (NR1) is a compound isolated from the roots of Panax notoginseng; it has powerful ROS-scavenging activities.

Effects of boar sperm antioxidant supplementation on fertility
Animal Reproduction Science, 2022Use of cooled stored boar semen for artificial insemination accounts for 99% of inseminations in pork production sectors worldwide. The aim of the present study was to examine use of GameteGuard®-CP, a natural plant derived blend of antioxidants, supplemented in one commercially available semen extender on sperm quality, conception rate, farrowing rate,

Sperm Cryopreservation in Boars
Cryopreservation is the procedure that allows preserving cells, including gametes, for long time periods while maintaining their functionality, through the use of cryogenic temperature. Currently, sperm cryopreservation is a crucial-assisted reproductive biotechnology in pigs since it is the only effective and efficient method for long-term ...Inmaculada, Parrilla +3 more

Effect of dietary selenium on boar sperm quality
Animal Reproduction Science, 2013The primary objective of this research was to evaluate the effect of long-term dietary selenium supplementation of commercial swine diets on semen production and sperm quality. The dietary treatments were a non-supplemented basal diet or the basal diet supplemented with 0.3ppm selenium in either an organic or inorganic form.

Dynamics of heparin-binding proteins on boar sperm
Animal Reproduction Science, 2009The presence, topology and dynamics of heparin-binding proteins (HBP) on boar sperm were evaluated. HBP distribution was analyzed by subcellular parting, using biotinylated heparin followed by colorimetric detection. HBP were detected as peripherical and integral periacrosomal membrane proteins.

Reproductive toxicology of 2,4 dinitrophenol in boar sperm
Toxicology in Vitro, 2016Abstract The aim of this study was to evaluate the toxic effects of 2,4 dinitrophenol (DNP) on swine spermatozoa; particularly plasma membrane fluidity and integrity, mitochondrial function and motility, including oxidative stress parameters of lipid peroxidation and production of reactive oxygen species, when cooling to 17 °C during 24 to 96 h.

Expanded cumuli induce acrosome reaction in boar sperm
Molecular Reproduction and Development, 1998The authors investigated acrosomal changes occurring in boar sperm that interact with the expanded cumulus matrix surrounding ovulated pig oocytes. Samples of washed boar sperm obtained from six donors were incubated for 4 hr under capacitating conditions and exposed either to solubilized zonae pellucidae (ZP) or solubilized expanded pig cumuli (SEC ...

Autophosphorylation of boar sperm membranes.
Biochemistry international, 1986Boar sperm plasma membranes and the membranes released during an in vitro acrosome-like reaction were capable of autophosphorylation. The purified membranes were incubated in Tyrode's buffer containing [32P]ATP with or without Ca2+ and/or diacylglycerol.

Seminal plasma affects sperm sex sorting in boars
Reproduction, Fertility and Development, 2016Two experiments were conducted in boar semen samples to evaluate how both holding time (24 h) and the presence of seminal plasma (SP) before sorting affect sperm sortability and the ability of sex-sorted spermatozoa to tolerate liquid storage. Whole ejaculate samples were divided into three aliquots immediately after collection: one was diluted (1 : 1,
