OBJECTIVES To evaluate associations between cumulative and peak formaldehyde exposure and mortality from acute myeloid leukemia (AML) and other lymphohematopoietic malignancies. METHODS Cox proportional hazards analyses. RESULTS Acute myeloid leukemia was unrelated to cumulative exposure. Hodgkin lymphoma relative risk estimates in the highest exposure categories of cumulative and peak expo...

background: immune thrombocytopenic purpura (itp) is a disease characterized by decrease of the peripheral blood platelet count. the disease presents in acute and chronic forms. because of the importance and high prevalence of itp, it was decided to study the therapeutic response of patients with itp. material and methods: a cross-sectional study was conducted at ghaem hospital, mashhad, iran. ...

The volume of nanoparticles (NPs) used in various sectors human life is steadily increasing. Due to their unique properties, silicon dioxide (SiO2 NPs) are widely industrial production. However, ecotoxicological effect on marine biota extremely poorly understood. To highlight this problem, experiments were conducted with short-term SiO2 NPs exposure the sand dollar Scaphechinus mirabilis sperm,...

Methods: Considering the inclusion and exclusion criteria, 30 participants were selected through purposive sampling method among the caregivers of acute and chronic schizophrenic patients. The sample answered to WHO Quality Of Life (WHOQOL-100) and demographic ...

BACKGROUND This study demonstrates the changes in six different pathophysiological parameters such as body weight, body temperature, fecal pellet count, blood-brain barrier (BBB) permeability, plasma corticosterone level and emergence of hemorrhagic peptic ulcer spots due to exposure to high environmental heat in three different age groups of freely moving rats. METHODS Each age group of rats...

the aim of this study was to investigate the radioprotective effect of thymol as a natural product against salivary glands dysfunction induced by ionizing radiation in rats. the rats were treated with thymol at dose of 50 mg/kg before exposure to radiation at dose 15gy. salivary gland function was evaluated with radioisotope scintigraphy and then salivary gland to background counts ratio was ca...

objective(s): our previous studies have shown that mgo nanoparticles (mgo nps) could improve anxiety and reduce pain in animals. in this study, the effect of co administration mgo nps and vitamin c on anxiety like behavior and nociception in postpartum depression (ppd) model were investigated.materials and methods:  female mice (27 ± 3 g) were divided into groups: two control groups, ppd groups...

Exposure to second hand smoke is a major cause of chronic obstructive pulmonary disease (COPD) in the non-smoker. In this review we explore the use of animal smoke exposure models and their insight into disease pathogenesis. The methods of smoke exposure, including exposure delivery systems, are described. Key findings from the acute and chronic smoke exposure models are outlined, including des...
