Endogenous testosterone (T), LH and FSH receptors, and in vitro production of cyclic adenosine-3':5'-monophosphate (cAMP), T and some of its steroid precursors were measured in testicular tissue obt...
Relationship of human sperm acrosin and proacrosin to semen parameters. II. Correlations
human sperm acrosin semen parameters
2009/2/23
Previous results, simultaneously confirmed by others, suggest that a relationship exists between sperm acrosin levels and fertility in man. The assessment of sperm acrosin may therefore be a useful ...

II. Characterization and development of the regional- and cellular-specific abnormalities in the epididymis of mice with beta-hexosaminidase A deficiency
II. Characterization regional- and cellular-specific abnormalities epididymis mice with beta-hexosaminidase A deficiency
2009/2/18
Beta-hexosaminidase (Hex) is a lysosomal enzyme that exists as two isoenzymes: Hex A (subunit structure alphabeta) and Hex B (betabeta). Its presence in the testis and epididymis suggests importan...
Rat seminal-vesicle secretory protein SVS II binds DNA with a preference for the 5' regulatory region of secretory protein SVS IV gene：co-isolation with components of the nuclear matrix
caltrin nuclear scaffold nuclear structure semen tissue
2009/2/18
In rats, the ventral prostate and seminal vesicles produce distinct sets of proteins whose functions and tissue-specific regulation by androgens remain unclear. We have utilized the genes encoding t...
Anti-bull sperm monoclonal antibodies：II. Binding changes during capacitation and influence on sperm-zona interactions in vitro
Bull sperm sperm-zona binding capacitation
2009/2/16
Anti-bull sperm monoclonal antibodies (mAbs), generated against intra-acrosomal and surface antigens, were evaluated for their functional significance. In experiment I, the influence of mAbs on the bo...
