The Caspian trout is an endangered and quite vulnerable fish, considered for a natural protection program in the southern area of the Caspian Sea. Copper oxide nanoparticles (CuO-NPs) are toxic substances, which induce oxidative stress, not to mention other pathophysiological states. The toxicity of nanoparticles on fish needs more characterization for short- and long-term effects.  Thus, the p...

The purpose of this study was to analyze the health risks benzene exposure, on human health, especially for workers/employees engaged in oil industry. To assess effects workers, it obtained from data workers exposed work environment. Acute exposure (14 days), moderate (15-364 days) and chronic (365 are workplaces where is below Minimum Risk Level (MRL) value inhaled that reduced by ATSDR acute,...

human brucellosis is a major health problem in developing countries. a number of patients with human brucellosis do not recover from the acute stage of the disease and pass into the chronic form. since the pathophysiology of this change is not well understood, we studied the t-cell subsets during the acute, subacute and chronic forms of human brucellosis. in this study we found alterations in t...

Although the negative inotropic effects of both acute and chronic ethanol (EtOH) exposure are well known, little is known concerning the acute-to-chronic transition of such effects. In this study, our objective was to address this question by detailing the effects that acute EtOH exposure induces on cellular excitation-contraction (EC) coupling and, subsequently, comparing whether and how such ...

Background: Urticaria is a common skin disease characterized by transient and itchy swelling. The spectrum of etiologic factors in urticaria is very wide and contains external factors such as drugs, foods and internal diseases such as infections, SLE, hormonal factors and even lymphoma. Objective: To determine different kinds of urticaria and different etiologic and prevocational factors in pat...

Reactive airway dysfunction syndrome (RADS) is a type of non-immunologically mediated asthma-like disease. It usually occurs after a massive exposure to an irritating substance in the atmosphere in the form of smoke, fumes, gases, and vapor. Unlike bronchial asthma, there is no latency to the symptoms seen in RADS. A number of agents are known to cause RADS, but tile dust, as an etiological age...

Background To attain whether the effects of low and high doses of estrogen progesterone luteinizing hormone (LH) and follicle stimulating hormone (FSH) in acute and chronic administration were related to oxidant and antioxidant parameters in rat uterine tissue as well as cyclooxygenase-1 (COX-1) activity. MaterialsAndMethods Acute and chronic administration of estrogen (1 and 5 mg/ kg) progeste...
