Background & Aim: Despite valuable medicinal properties of safflower, breeding new varieties and development of the crop culture area has been limited due to the lack of genetic variation for some crucial characteristics as resistance to diseases and pests like safflower fly. In this study, populations of wild safflower, C. oxyacanthus were collected from western, central and ...
For the identification of phylogenetic characteristics of honeybee populations, sampling was conducted from 31 provinces of Iran in spring and summer 2016. Phylogenetic characteristics were evaluated based on mitochondrial ND2 gene. The intergenic regions between ND2 and COI genes were compared in different populations of honeybees. After sequencing and alignment of the genes, the relationships...
An investigation was conducted in order to determine the etiological factors of Fry Mortality Syndrome (FMS) that causes a serious economical loss in rainbow trout’s farms in Iran and around the world. The increased number of farms and the improvement of culture techniques and facilities in Iran had boosted the annual production of trout from 280 tonnes in 1978 to more than 30,000 tones in 2004...

امواج گرمایی به عنوان یک مخاطره اقلیمی در سال های اخیر رخداد بیشتری داشته اند که این امر از تظاهرات تغییرات آب و هوایی کره زمین به شمار می رود. در این پژوهش به منظور بررسی آماری و همدید امواج گرمایی فرین غرب ایران از داده-های دمای حداکثر روزانه ایستگاه های همدید استان های لرستان، کردستان، کرمانشاه و همدان در دوره آماری بلند مدت (1961-2010) استفاده شد. برای شناسایی و تحلیل دماهای فرین منطقه غرب ...
The First National Conference on Advances in Superconductivity was the first of a series of conferences in the field of superconductivity planned to be held biannually in one of the universities or scientific research centers in the country. The goal of these meetings is to bring together groups of researchers in the field of experimental and theoretical superconductivity, to discuss their la...
Dong Y, Qi B, Feng XY, Jiang CM. Meta-analysis of Barrett's esophagus in China. World J Gastroenterol 2013;19(46):8770-8779 The disease pattern of Barrett's esophagus (BE) in China is poorly characterised particularly in comparison with other developed countries. This meta-analysis of 3873 cases of BE collated from 69 clinical studies conducted in 25 provinces between 2000 and 2011 investigated...
Global temperatures have increased in the past 100 years by an average of 0.74°C (IPCC, 2013), with minimum temperatures increasing faster than maximum temperatures and winter temperatures increasing faster than summer temperatures (IPCC, 2013). Total annual rainfall tends to increase at the higher latitudes and near the equator, while rainfall in the sub-tropics is likely to decline and become...
