Effects of methyl-beta-cyclodextrin on cryosurvival of boar spermatozoa
methyl-beta-cyclodextrin cryosurvival boar spermatozoa
2008/12/26
Methyl-beta-cyclodextrin (MBCD), which leads to the stimulation of cholesterol efflux from the cell membrane, was examined for its ability to increase the cryosurvival of spermatozoa from Gottingen mi...
Sperm Sorting Procedure Induces a Redistribution of Hsp70 but Not Hsp60 and Hsp90 in Boar Spermatozoa
Flow cytometry heat shock protein 60 heat shock protein 70 heat shock protein 90 pig
2008/12/24
Heat shock proteins, besides their protective function against stresses, have been recently indicated as key factors for sperm fertilizing ability. Since sexing sperm by high-speed flow-cytometry su...
Immunolocalization and Possible Functional Role of PSP-I/PSP-II Heterodimer in Highly Extended Boar Spermatozoa
Reproductive tract semen sperm seminal plasma sperm capacitation
2008/12/24
PSP-I/PSP-II heterodimer is a major protein of boar seminal plasma which is able to preserve, in vitro, the viability, motility, and mitochondrial activity of highly extended boar spermatozoa for at...
Supplementation of the Thawing Media With Reduced Glutathione Improves Function and the In Vitro Fertilizing Ability of Boar Spermatozoa After Cryopreservation
Pig spermatozoa oxidative stress IVF capacitation status
2008/12/23
In this study, we evaluated the effects of glutathione (L-g-glutamyl-L-cysteinylglycine; GSH) supplementation of the thawing extender on semen parameters to compensate for the decrease in GSH conten...
A Cyclic Adenosine 3',5'-Monophosphate Stimulates Phospholipase C1-Calcium Signaling via the Activation of Tyrosine Kinase in Boar Spermatozoa
Sperm cAMP SYK PLC calcium store
2008/12/23
The aim of this study was to reveal a downstream part of the intracellular signaling that is mediated by cyclic adenosine monophosphate (cAMP)-dependent tyrosine kinases, including spleen tyrosine (...
Kinematic Changes During the Cryopreservation of Boar Spermatozoa
Kinematic parameters sperm subpopulations pig
2008/12/23
The present study evaluates the effect that various steps of a conventional cycle of cryopreservation have on the patterns of movement exhibited by boar spermatozoa. Sperm-rich ejaculate fractions c...
Cooling and Freezing of Boar Spermatozoa:Supplementation of the Freezing Media With Reduced Glutathione Preserves Sperm Function
Pig spermatozoa antioxidants cryopreservation in vitro fertilization capacitation status
2008/12/23
In this study, we evaluated the effects of glutathione (L--glutamyl-L-cysteinylglycine; GSH) supplementation of the freezing extender on semen parameters during the cooling (2 hours at 5°C) and free...
Survival and In Vitro Fertility of Boar Spermatozoa Frozen in the Presence of Superoxide Dismutase and/or Catalase
Antioxidants cryopreservation sperm porcine
2008/12/22
In the present study the potential benefit of reactive oxygen species (ROS)-scavenging enzymes superoxide dismutase (SOD) and catalase (CAT) when cryopreserving boar spermatozoa was evaluated. Poole...
Does Seminal Plasma PSP-I/PSP-II Spermadhesin Modulate the Ability of Boar Spermatozoa to Penetrate Homologous Oocytes In Vitro?
Seminal plasma preservation sperm viability IVF pig
2008/12/22
Low concentration (0.15 mg per million of spermatozoa) of seminal plasma–derived PSP-I/PSP-II spermadhesin heterodimer is able to preserve the viability of highly extended boar spermatozoa. Whether ...
Survival and Fertility of Boar Spermatozoa After Freeze-Thawing in Extender Supplemented With Butylated Hydroxytoluene
Antioxidants cryopreservation sperm porcine
2008/12/22
This study evaluated the protective effect of butylated hydroxytoluene (BHT), a lipid-soluble antioxidant, against cryopreservation injuries to boar spermatozoa. In experiment 1, the lowest BHT conc...
