Leishmaniasis is a common parasitic disease classified to acute and chronic types based on the duration of the disease. The acute lesion is presented as ulcerated papule and nodule that heal after a few months with an atrophic scar. The chronic form of cutaneous leishmaniasis is a nonhealing lesion that is persistent for more than one year. Here, we describe a chronic case of leishmaniasis deve...

the aim of this study was to measure the alterations in serum zinc (zn) copper (cu) and iron (fe) concentrations in patients with acute and chronic cutaneous leishmaniasis. serum zinc and copper were measured by flameless atomic absorption spectrophotometer and serum iron concentration was measured by the ferrozine method with commercial kits and assay was carried out by using an automatic anal...

PURPOSE Hyperglycemia, a hallmark of diabetes mellitus, is associated with retinal inflammation and impairment of endothelium-dependent nitric oxide (NO)-mediated dilation of retinal arterioles. However, molecular mechanisms involved in this diminished endothelial vasodilator function remain unclear. We examined whether inflammatory stress-activated kinases, c-Jun N-terminal kinase (JNK) and p3...

Introduction: Anthroponotic cutaneous leishmaniasis (ACL) is still a major public health problem in the northeast and central parts of Iran. This study was designed to compare microscopy and cultivation methods with PCR amplification of kinetoplast DNA and ITS1 followed by RFLP analysis for diagnosis of acute and chronic ACL. Methods: In this study, 66 patients with ACL including 24 acute and 4...

Background and Objective: Monoarthritis is the inflammation of a single joint. There is limited data on the etiology of monorthritis in Iran. This study was aimed to evaluate epidemiologic charecteristics of the patients with monorthritis in Kashan, Iran. Materials and Methods: This cross-sectional study was conducted on 227 patients with monorthritis referred to the rheumatology clinic of Kas...

The degree to which ozone (O 3 ) exposure and drought affect stomatal control of water loss respond environmental stimuli such as varying light is poorly characterized. To that end, we exposed Pima cotton chronic O (month-long daytime exposures) with without sufficient water, well short term acute levels understand kinetics. Chronic, month-long moderately high (~114 ppb) reduced steady state co...

it has recently been shown that ror1, a member of the receptor tyrosine kinase family, is overexpressed in leukemic b cells of chronic lymphocytic leukemia (cll) and a subset of acute lymphoblastic leukemia (all). in this comparative study the expression profile of ror1 mrna was investigated in iranian patients with cll and acute myelogenous leukemia (aml) and the results were compared with tho...

Cardiovascular performance is altered by temperature in larval fishes, but how acute versus chronic temperature exposures independently affect cardiac morphology and physiology in the growing larva is poorly understood. Consequently, we investigated the influence of water temperature on cardiac plasticity in developing mahi-mahi. Morphological (e.g. standard length, heart angle) and physiologic...

For the use of topical insect repellents, DEET and picaridin, human health risk assessments were conducted for various population subgroups. Acute, subchronic, and chronic dermal exposures were examined. No-observed-effect-levels (NOELs) of 200, 300, and 100mg/kg body weight (BW) were used as endpoints for DEET for acute, subchronic, and chronic exposures, respectively. For picaridin, a NOEL of...
