since the difference in productivity growth rates in different provinces is a result of regional inequality, efficiency criteria in the development of regional-scale agricultural activities is beneficial. therefore it is important that long-term movements in the provinces to identify differences in productivity levels to take effective measures such as investment more in infrastructure, researc...

Genetic diversity as an important marker of the ecological status of aquatic ecosystems is considered a unique and powerful tool to evaluate biological communities. In order to evaluate the genetic diversity among golden mullet species (Liza aurata) in the southeast and southwest coasts of the Caspian Sea by D-Loop gene sequencing, a total of 23 fin specimens of golden mullet were collected fro...

in the last decades, pesticides have been used extensively, in order to control pests and plant diseases, but negative impacts of pesticides caused several environmental problems and put human health in danger. in order to decrease environmental hazards of pesticide, risk of pesticide application should be measured briefly and precisely. in this study environmental impacts of registered insecti...

an experiment was carried out in 2008-2009 to study the correlation between the reaction to potassium chlorate and pathogenicity on some iranian isolates of macrophomina phaseolina, the causal agent of soybean charcoal rot. from among a total of 48 collected isolates from the major soybean cultivation areas of golestan, mazandaran, ardabil, and lorestan provinces, twenty four isolates were sele...

Antifungal and antibacterial activity of some heterocystous cyanobacteria from paddy-fields in the north of Iran was studied. Soil samples were collected from paddy-fields of Gillan, Mazandaran and Golestan Provinces and cyanobacteria were isolated. Supernatants, methanolic and hexane extracts from biomass of 150 strains of cyanobacteria were isolated and screened against six strains of bacteri...

In order to determine soil inhabitant fungi of Mazandaran and Golestan provinces (N Iran), some soil samples from arable and non-arable areas were collected. After the isolation, purification and identification of fungi, 61 isolates, belonging to Absidia, Actinomucor, Cunninghamella, Lichtheimia, Mucor, Syncephalastrum and Rhizopus were identified. After DNA extraction, all genera were subjecte...

AIM To correct the misclassification in registered gastric cancer incidence across Iranian provinces in cancer registry data. METHODS Gastric cancer data is extracted from Iranian annual of national cancer registration report 2008. A Bayesian method with beta prior is implemented to estimate the rate of misclassification in registering patient's permanent residence in neighboring province. Ea...

Objective: The aim of this study was to estimate genetic variability and phonetic relationships of 50 isolates of P. sojae from Iran. Methods: During 2005–2007, 142 isolates of Phytophthora sojae were collected from soil samples and diseased soybean plants from Lorestan, Mazandaran, Golestan and Ardabil provinces. Races of the isolates were determined. DNA of P. sojae...

Aim The aim of this study was to obtain more accurate estimates of the liver cancer incidence rate after correcting for misclassification error in cancer registry across Iranian provinces. Background Nowadays having a thorough knowledge of geographic distribution of disease incidence has become essential for identifying the influential factors on cancer incidence. Methods Data of liver canc...
