Effect of heparin on in vitro capacitation of boar sperm.
Chlortetracycline (CTC) fluorescent pattern, the ability to undergo acrosome reaction (AR) upon exposure to 10 microM calcium ionophore A23187 and vitality estimation were used to investigate the effect of the sulfated glycosaminoglycan heparin on the in vitro capacitation of porcine spermatozoa. Sperm incubation in capacitating medium (CM) supplemented with 10 mM heparin for up to 120 min, sho...
متن کاملEffect of estrogens on boar sperm capacitation in vitro
BACKGROUND Mammalian sperm must undergo a series of controlled molecular processes in the female reproductive tract called capacitation before they are capable of penetrating and fertilizing the egg. Capacitation, as a complex biological process, is influenced by many molecular factors, among which steroidal hormone estrogens play their role. Estrogens, present in a high concentration in the fe...
متن کاملP-61: Inhibitory Effect of Simultaneous Exposure to Formaldehyde Vapour and Noise on Mouse Sperm Kinematic Parameters and Sexual Hormones
Background: This study aimed to investigate the inhibitory effects of simultaneous formaldehyde (FA) and noise exposure on the sperm kinematic parameters sexual hormones in male mice. Materials and Methods: Forty eight NMRI adult male mice were randomly assigned to control group and experimental groups which were exposed to formaldehyde vapour (10 ppm) (F), noise (100 dB) (N), and simultaneous ...

this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...
15 صفحه اولCluster analysis reveals seasonal variation of sperm subpopulations in extended boar semen
This study aimed to identify motile sperm subpopulations in extended boar semen and to observe the presumptive seasonal variation in their distribution. Data from 4837 boar ejaculates collected over a two-year period were analyzed in terms of kinematic parameters by Computer Assisted Sperm Analysis (CASA). Individual sperm data were used to determine subgroups of motile sperm within the ejacula...
