Recent attitude of vegetation assessors is using of new ecologic approaches to evaluate and analyse the complex rangeland ecosystems. Plant diversity is the most important indices to assess the ecological changes of rangelands. In order to survey of plant indices of rangelands, two exclosure areas (long-term and mid-term) and a grazing area in rangelands of Javaherdeh (Ramsar, Iran) were select...

Abstract Background: Diabetic patients are more prone to oral infections and periradicular lesions due to changes in their immune system and qualitative and quantitative changes in normal flora of their mouth. The aim of this study was to evaluate the frequency of periradicular lesions in diabetic patients in Babol, North of Iran. Methods: From October 2011 to March 2012, 135 diabetic patient...

we aimed to evaluate clinical, high resolution computed tomography (hrct) and pulmonary function test (pft) findings after 18-23 years of exposure in veterans of sulphur mustard (sm) exposure. we performed a cross-sectional study of 106 patients. inclusion criteria were 1: documented exposure to sm as confirmed by toxicological analysis of their urine and vesicular fluid after exposure 2: singl...

the influence of long-term mixed organic and inorganic contamination on soil microbial activity, community structure and genetic diversity was investigated in soil samples from a coke oven plant located in upper silesia, poland. the tested soils were heavily contaminated with polycyclic aromatic hydrocarbons (pahs) and heavy metals. the microbial communities were characterized using the phospho...

Background Over the last decade there has been an increase in healthcare expenditures while at the same time the inequity in distribution of resources has grown. These two issues have urged the researchers to review the determinants of healthcare expenditures. In this study, we surveyed the determinants of health expenditures in Economic Cooperation Organization (ECO) countries.   Methods We us...

background: spermatogonial stem cells are subpopulation of spermatogonial cells in testis tissue that support beginning and maintenance of spermatogenesis. ubiquitin carboxy-terminal hydrolase l1 (uchl1) could be a specific marker for identification of spermatogonial stem cells including spermatogonial sperm cells (sscs) in testis tissue and during the culture; therefore we undertook this study...

introduction: previous studies indicate that exercise influences cognitive function. nevertheless, considering that exercise in animal study can be voluntary, or forced, effects of exercise (specially forced exercise) on learning and memory abides as a matter of controversy. the present study aimed to investigate the effects of treadmill exercise on ltp in the dentate gyrus of rats. methods: th...

introduction: over the last decade, exposure to non-ionizing electromagnetic waves due to base station antenna has increased. this in vivo study was planned for evaluating the effects of whole-body exposure to 950 mhz field of gsm mobile phone system on rat dentate gyrus long-term potentiation. materials and methods: 24 naive male wistar rats (3 month old, 225|¡|25 g) were randomly divided in t...

sewage effluent is the carrier of huge amounts of n (0.09 to 0.16%), p (0.023 to 0.029 %), and k (0.11 to 0.18%) and as well as it is rich in organic carbon (3.27%). transfer of the toxic trace metal (pb) from the contaminated site can be seized out from the food chain through application of feso4.7h2o and caso4 in a larger area. the efficacy of the toxic metal immobilization through an applica...
