BACKGROUND The aim of the study was to determine the incidence of non-bacterial acute gastroenteritis associated with diarrheal diseases in Mazandaran Province, northern Iran. METHODS A total of 400 symptomatic cases from patients with acute gastroenteritis from Mazandaran Province in Iran were screened using EIA method for the presence of rotavirus, adenovirus and astrovirus during 2005-2006...

INTRODUCTION Hemoglobin Q-Iran (α75Asp→His) is an important member of the hemoglobin Q family, molecularly characterized by the replacement of aspartic acid by histidine. The first report of hemoglobin Q-Iran and the nomenclature of this hemoglobinopathy dates back to 1970. Iran is known as a country with a high prevalence of α- and β-thalassemia and different types of hemoglobinopathy. Many of...

BACKGROUND T-2 toxin is a mycotoxin that is produced by the Fusarium fungi. Consumption of food and feed contaminated with T-2 toxin causes diseases in humans and animals. OBJECTIVES In this study T-2 toxin was analyzed in poultry and cattle feedstuff in cities of Mazandaran province (Babol, Sari, Chalus), Northern Iran. MATERIALS AND METHODS In this study, 90 samples were analyzed for T-2 ...

The Universal Soil Loss Equation (USLE) and its derivatives are widely used for identifying watersheds with a high potential for degrading stream water quality. We compared sediment yields estimated from regional application of the USLE, the automated revised RUSLE2, and five sediment delivery ratio algorithms to measured annual average sediment delivery in 78 catchments of the Chesapeake Bay w...

An allocation scheme of water pollutant reduction is the key procedure to implement a watershed total maximum daily load (TMDL) program. In order to improve the equity for the allocation scheme of water pollutant load reduction, five indexes involved in allocation processes were selected from fields associated with society, environment, economics, and resources. The weights of these indexes wer...

BACKGROUND Recurrent pregnancy loss (RPL) is caused by different factors, including genetics and thrombophilia. Beside Factor V Leiden, another nucleotide change in a factor V (FV) gene (A4070G; His1299Arg) has been identified linking to hereditary thrombophilia. Also, two proposed MTHFR polymorphisms, C677T and A1298C (Glu429A) are linked with RPL. OBJECTIVE In this study, the effect of two ...

BACKGROUND Smoking is regarded as one of the main risk factors and additive to the global burden of diseases in the World. OBJECTIVES This individual patient data (IPD) meta-analysis aimed to estimate the smoking prevalence in Mazandaran province of Iran. MATERIALS AND METHODS This study was an IPD meta-analysis. The study data were part of the STEPS Study in Mazandaran province (northern I...

Land use and land cover across 28 sub-basins within the Cosumnes Watershed, CA (1989 km) were correlated to nitrate-N and total suspended solids (TSS) loading between water years 1999 and 2001. The impact of human development on stream water quality was evident as both agricultural area and population density predicted TSS loading in a linear mixed effects model. In contrast to the TSS model, t...

The Soque River Watershed Partnership received CWA §319 funding to perform a comprehensive baseline assessment of the biological, chemical, and physical health of the watershed. Certain stream segments in the Soque basin violate State water quality standards for bacteria and sediments. The assessment is designed to identify and prioritize areas for both protection and remediation. Rapid bioasse...

nowadays soil erosion is considered as a serious threat to human's life and his welfare. when soil erosion not properly controlled, the fertility would gradually decrease. adoption of appropriate soil conservation practices along with socio-economic factors' assessment can be used to increase farmers' awareness and acceptance of soil conservation, and to diminish soil erosion dam...
