background: the relationship between metabolism and reproduction has been always considered as an important topic in female endocrinology. it seems that leptin is one of the involved factors in infertility. leptin, in addition to regulating body weight plays an important role in regulation of endocrine, reproductive and immune systems. the aim of this stduy is to compare serum and follicular fl...

objective(s): one applications of nanotechnology is in the area of medicine which is called nanomedicine. primary instruments in nanomedicine can help us to detect diseases and used for drug delivery to inaccessible areas of human tissues. an important issue in simulating the motion of nanoparticles is modeling blood flow as a newtonian or non-newtonian fluid. sometimes blood flow is simulated ...

3. Protective barriers Appropriate gloves for the task should be utilised to provide an effective barrier against infectious materials (blood, body fluids) and chemicals. Health care workers must also wear masks, protective eye wear, face shields and/or fluid resistant attire when appropriate. 4. Double glove Health care practitioners should use two pairs of gloves during invasive procedures. A...

It has been hypothesized that exposure to heavy metals may impair male reproduction. To measure the effect produced by low doses of heavy metals on semen parameters, it is necessary to clarify in which body fluids those measurements must be performed. Sixty-one men attending infertility clinics participated in our study. Concentrations of lead, cadmium, and mercury were measured in whole blood,...

background: mercury is widespread and persistent in the environment. one organic form of mercury, methylmercury (mehg), can accumulate in the food chain in aquatic ecosystems and lead to high concentrations of mehg in fish, which, when consumed by humans, can result in an increased risk of adverse effects. currently, the joint fao/who expert committee on food additives (jecfa) has established p...

Background: Cadmium (Cd) is an extremely toxic metal and environmental exposure to Cd has been particularly problematic in the world. Oral exposure to Cd may result in adverse effects on a number of tissues, the immune system, and the cardiovascular system. Compounds containing Cd are also carcinogenic. The presence of Cd in drinking water resources in the southeastern region of Rafsanjan plain...
