Levels of hepatocyte growth factor/scatter factor（HGF/SF）in seminal plasma of patients with andrological diseases
Testis spermatozoa male infertility
2009/2/17
Hepatocyte growth factor/scatter factor (HGF/SF) has all the characteristics of a molecule suitable for functioning in regulatory networks of motility, such as the spermatogenic epithelium, where sper...
Improvement of cryopreserved ram sperm heterogeneity and viability by addition of seminal plasma
cryopreserved ram sperm heterogeneity seminal plasma
2009/2/17
The effect of seminal plasma, as well as some seminal plasma fractions, on the heterogeneity and viability of frozen-thawed ram spermatozoa was studied. Fresh and frozen sperm samples were simulta...
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 ...
Seminal plasma lactoferrin concentrations in normal and abnormal semen samples
Leucocytospermia oligospermia asthenospermia infertili
2009/2/17
Although the iron-chelating protein lactoferrin is secreted by the seminal vesicles, the precise role of lactoferrin in semen is unclear. This study aimed to determine whether there is any association...
Cytokine levels in the seminal plasma of infertile males
Infertility semen cytokines human sperm urogenital infection
2009/2/16
Cytokines released by various cell subsets in the male urogenital tract are capable of markedly influencing sperm function and fertility. We determined the cytokine content in the seminal plasma o...
Immunoreactive parathyroid hormone-related protein is present in human seminal plasma and is of prostate origin
Immunoreactive parathyroid hormone-related protein human seminal plasma
2009/2/12
Parathyroid hormone-related protein (PTHrP) is a regulatory peptide that has been associated with normal fetal growth and differentiation as well as the regulation of fetal calcium. We recently d...
Increased levels of interleukin-6 in seminal plasma of infertile men
Increased levels interleukin-6 seminal plasma infertile men
2009/2/12
The presence of various cytokines, namely the tumor necrosis factor (TNF-alpha), interferon (IFN-gamma), and interleukins (IL-1 beta and IL-6), was investigated in seminal plasma of fertile, infer...
Platelet-activating factor acetylhydrolase activity in bovine seminal plasma
Platelet-activating factor acetylhydrolase activity bovine seminal plasma
2009/2/12
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...
Soluble Fc gamma RIII（CD16）and immunoglobulin G levels in seminal plasma of men with immunological infertility
Enzyme-linked immunosorbent assay (ELISA) immunosuppression
2009/2/12
Receptors for the Fc region of the immunoglobulin G (IgG) (Fc gamma R) have been recognized as a link between humoral and cellular immune responses. A soluble form of Fc gamma RIII (CD16) has been...
Immunoreactive ubiquitin in human seminal plasma
Immunoreactive ubiquitin human seminal plasma
2009/2/12
The polypeptide ubiquitin, up to now almost exclusively discovered in intracellular spaces, was measured immunologically in a total of 187 samples of human seminal plasma. The values were between 1....
Objectively measured sperm motility and sperm head morphometry in boars（Sus scrofa）：relation to fertility and seminal plasma growth factors
sperm motility sperm head morphometry fertility seminal plasma growth factors
2008/12/26
This study was conducted to investigate the relationships between results of computer-assisted semen analysis (spermatozoal motility and sperm head morphometry) and fertility of boars. In addition, ...
Quantification of the nonenzymatic fast and slow TRAP in a postaddition assay in human seminal plasma and the antioxidant contributions of various seminal compounds
Quantification nonenzymatic fast and slow TRAP postaddition assay human seminal plasma seminal compounds
2008/12/25
Total radical-trapping antioxidant potential (TRAP) measurements of human seminal plasma (N = 25) were performed by using a post-addition assay based on trapping 2,2' Azino-bis(3-ethylbenzthiazoline...
Seminal plasma glycodelin and fertilization in vitro
Seminal plasma glycodelin fertilization in vitro
2008/12/25
Endometrium-derived glycodelin-A inhibits sperm-egg binding, whereas differentially glycosylated seminal plasma glycodelin-S does not. The difference has been ascribed to the specific type of glycos...

biochemical etiology human seminal plasma hyperviscosity
2008/12/25
Semen rheology was studied to elucidate the biochemical basis of seminal plasma hyperviscosity. Semen proved to fit in with a power law model, by presenting a pseudoplastic behavior. Apparent vi...
