Background: Strenuous exercise and temperature outside the optimum are associated with hypothalamic dysfunction and therefore disruption of fertility in females. The aim of this study was to evaluate serum Estradiol level and follicogenesis in adult mice exposed to forced swimming in different temperature waters. Materials and Methods: Adult female mice were randomly divided into four groups as...

Autism is a severely incapacitating condition that typically appears during the first 3 years of life and is characterized by severe communication and other developmental and educational problems. Children with autism generally demonstrate poor motor skills. Consequently, rehabilitation programs should emphasize fundamental motor skills and patterns of movement, individual games and sports, and...

1. Cyclical swimming behaviour of the cercariae of the digenetic trematode, Proterometra macrostoma, involves a highly regular alternating swim-sink sequence. During periods of swimming the cercariae are propelled upward through the water by alternating lateral contractions of the tail. Following each burst of swimming the cercariae passively drift downward. 2. Suction electrode recordings from...

To understand the mechanics of fish swimming, we need to know the forces exerted by the fluid and how these forces affect the motion of the fish. To this end, we developed a 3-D computational approach that integrates hydrodynamics and body dynamics. This study quantifies the flow around a swimming zebrafish (Danio rerio) larva. We used morphological and kinematics data from actual fish larvae a...

Studies of maximum aerobic swimming performance in smolting juvenile salmonids indicate that these animals may be aerobically compromised during downstream migration. To test our hypothesis that hyperthyroid status contributes to decreased swimming performance through modification of muscle contractility in juvenile (112 mm mean total length) coho salmon (Oncorhynchus kisutch), we measured swim...

background: trihalomethanes are toxic and dangerous substances that are formed in the presence of organic materials when water is chlorinated for disinfection. the iranian national standard, world health organization, european :union:, u.s. environmental protection agency and international agency for research in cancer standards have established a maximum contaminant level for trihalomethanes f...

the fruit of cassia fistula linn. is a legume, has antioxidant and lots of other medicinal properties. as oxidants are involved in the pathogenesis of chronic fatigue syndrome, the present study was done to evaluate the effect of ethanolic extract of fruit pulp of c. fistula linn. (eecf) on forced swimming induced chronic fatigue syndrome (cfs). albino mice of 25-40 grams were grouped into five...

Individual Atlantic cod (Gadus morhua) were exercised using three different measures of swimming performance. (1) An endurance test (critical swimming speed, U(crit), protocol) designed to assess predominantly aerobic endurance swimming (duration hours). (2) An acceleration test (U(burst)), in which the fish were required to swim against a rapidly increasing current until exhausted (duration mi...

BACKGROUND Overexpression of lectin-like low density lipoprotein (LOX-1) receptor plays an important role in hyperglycemia-induced vascular complications such as atherosclerosis. Based on the beneficial effects of exercise on preventing cardiovascular complications of diabetes, we aimed to examine the protective effects of aerobic exercise on expression of LOX-1 receptor and production of free ...
