The properties of human sperm membrane CI~- channel reconstituted into giant liposome and the inhibition of male antifertility drugs on mouse spermatogenic cell Ca~2+channels
Results: The level of estrogen,the expression of TERT,and the number of the spermatozoon in high-and low-dose fluorine groups were lower than those of control group( P< 0.05).
The second principal component function is:Z 2=0.49192+ 0.08080X 1-0.00058X 2-0.00510X 3-0.01807X 4, which depends on the total amount of sperms (X 1).
When trypsin reacts with Herring sperm DNA (hsDNA), Salmon sperm DNA (sDNA), and Calf thymus DNA (ctDNA) to form a complex, the resonance Rayleigh scattering (RRS) was remarkably enhanced and new RRS spectra appear.
Structural and parameterized models for generalized description of the images of normal and pathologically changed cells of blood and sperm were presented by way of example.
The results show that quantitative and morphohistological trends in the development of sperm cells and Sertoli cells in both lines are similar in both lines.
At the same optical density of DNA, the sizes of mature spermatozoon heads in triploid males were, on average, 1.8 times smaller than in diploid males, as follows from the data obtained in summer 1996.
The results of similar studies carried out during the period of natural spawning activity in 1997-1999 suggest that the sizes of spermatozoon heads in triploid males were, on the contrary, 1.5 those in diploid males.
Difficulties in characterization of spermatozoa of the Metazoa are now related to insufficiency of the traditional terms "primitive spermatozoon," "modified spermatozoon," and "aberrant spermatozoon" introduced by G.
It is supposed that GAPDs exists in sperms as the tetrameric molecule bound to the fibrous sheath of the flagellum through the N-terminus of one or two subunits.
