Effects of platelet-activating factor and hyperbaric oxygenation on antioxidant defense and duodenal contractility
hyperbaric superoxide dismutase platelet antioxidant
2009/6/5
Platelet-activating factor (PAF) is a phospholipid mediator with potent biological effects on organisms. Some investigators have previously postulated that PAF exerts its effects by producing oxygen f...
Single-step isolation of bovine seminal platelet-activating factor acetylhydrolase
Seminal plasma phospholipase A2 protein purification
2009/2/17
Bovine seminal platelet-activating factor acetylhydrolase was isolated to >90% purity in a single step using a butyl sepharose column. The procedure involves the elution of the activity by use of ...
Partial purification and localization of platelet-activating factor acetylhydrolase from bovine seminal plasma
Partial purification platelet-activating factor bovine seminal plasma
2009/2/17
Platelet-activating factor (PAF) is a potent lipid mediator that is inactivated by platelet-activating factor acetylhydrolase (PAF-AH). Platelet-activating factor bioactivity has been detected in ...

Platelet-activating factor (PAF) is a potent signaling molecule that has been detected in mammalian sperm from several species. The biological function of sperm-derived PAF and mechanisms controllin...
High Seminal Platelet-Activating Factor Acetylhydrolase Activity in Men With Spinal Cord Injury
Sperm semen SCI asthenozoospermia infertility
2008/12/24
Spinal cord injury (SCI) causes male infertility, with low sperm motility the major long-term cause. It has been suggested in previous studies that some seminal components may be responsible for the...
A Review of the Effect of Platelet-Activating Factor on Male Reproduction and Sperm Function
Platelet-Activating Factor Male Reproduction Sperm Function
2008/12/5
Ten to 15% of reproductive age couples in the United States are not able to achieve a successful pregnancy and are considered infertile. Infertility affects men and women equally. Male fertility r...
β2 Integrin-dependent tyrosine phosphorylation of proline-rich tyrosine kinase 2 in platelet-activating factor-activated eosinophils
degranulation eosinophil β2 integrin PYK-2 tyrosine phosphorylation
2010/11/26
Platelet-activating factor (PAF) can activate various cellular functions, including degranulation in eosinophils. In the present study, we examined tyrosine phosphorylation of intracellular proteins i...
Platelet-activating Factor or Complement 5a Causes Distinct Activation Profiles in Human Eosinophil and Neutrophil Functions
adhesion complement 5a eosinophils neutrophils platelet-activating factor superoxide anion β2 integrin
2010/11/19
Eosinophils and neutrophils showed different activation profiles with stimulation of PAF or C5a on HSA-coated surfaces. In eosinophils the intensity of cellular adhesion and O2- release paralleled the...
