background: nicotine, cotinine and cadmium are harmful components of cigarettes that have an effect on human reproductive function. although the effects of cigarette smoke on male reproductive function is characterized in several articles its mechanism of action is still unknown. in the present study, we investigate the effect of nicotine, cotinine and cadmium on human sperm creatine kinase act...
Background and purpose : Muscle spindle is responsible for the control of skeletal muscle fibers function at rest and movement cycle, and is known as servo agent for voluntary movement. Function of this kinetic neceptor is completely dependent on the γ- ring activity would bring activity of la fiber and group ÏÏ spindle muscle afferent. Âlso, there is close functional of muscle relationship b...
The reliability of surface electromyographic (sEMG) variables during swallowing determines the potential usefulness of these measures in swallowing assessment and treatment. This study aimed to establish the reliability of the sEMG measures of the swallowing function of muscles during different swallowing conditions in healthy young and old volunteers. Two groups of volunteers (24 older adults,...
background: glycosidases profusion in male reproductive fluids suggests a possible relationship with sperm function. although hexosaminidase (hex) is the most active glycosidase in epididymal fluid and seminal plasma, as well as in spermatozoa, glucosidase is considered a marker for epididymal function and azoospermia. objective: the aim of this study was to determine hex activity in seminal pl...
