Genetic Relationships among Three Yarrow Species Based on Phenotypic Traits and Peroxidase Profiling
Fifteen yarrow populations from different species Achillea millefolium L., A. biebersteinii L. and A. nobilis, from different geographical areas of Iran were studied using 24 morphological traits and peroxidase profiles. Comparison of mean values of different phenotypic traits show A. millefolium and A. biebersteinii L. had higher plant height and crown diameter; however, A. nobilis had higher ...
نگرانیهای زیست محیطی در مورد استفاده بی رویه از آنتی بیوتیکها، باعث افزایش رشد استفاده از عوامل کنترل کننده طبیعی (bio-control) شده است. پلی بتا هیدروکسی بوتیرات (phb) یک پلی مر طبیعی می باشد که می تواند به اسید چرب کوتاه زنجیره محلول در آب تبدیل شود و به عنوان یک عامل کنترل کننده میکروبی عمل کند. در این آزمایش تاثیرات جایگزینی این ماده با جیره غذایی بچه ماهیان در 3 تیمار غذایی (کنترل،2 و 5 درص...
tobacco (nicotiana tabacum l.) is an important industrial crop and its seeds contain significant amounts of oil. the extraction of oil components using solvent at high pressure, or supercritical fluid (scf), has received much attention. in the present study, statistical analyses showed that the average extraction yield of seed oil of five tobacco varieties using sfe was 9.33%, which was higher ...
Knowing the rate of evapotranspiration (ET) from surface water resources such as lakes and reservoirs is essential for the precise management of water balance. Ardestan city with hot and dry climate is in Isfahan province (center of Iran), so in this region, water is very important. In this study, monthly ET was determined by several methods and equations for Ardestan city from 1993-2006. Month...

Reliable observations of the terrestrial environment are of crucial importance to understanding climate change and its impacts, to sustainable economic development, natural resources management, conservation, biodiversity and a scientific understanding of ecosystems and biogeochemical cycling. GOFC-GOLD (GLOBAL OBSERVATIONS OF FOREST COVER AND LAND DYNAMICS) as panel of GTOS (GLOBAL TERRESTRIAL...
Type 2 diabetes (T2D) is increasing in prevalence at an alarming rate around the world. Much effort has gone into the discovery and design of antidiabetic drugs; however, those already available are unable to combat the underlying causes of the disease and instead only moderate the symptoms. The reason for this is that T2D is a complex disease, and attempts to target one biological pathway are ...
Programmed death-1-directed (PD-1-directed) immune checkpoint blockade results in durable antitumor activity in many advanced malignancies. Recent studies suggest that IFN-γ is a critical driver of programmed death ligand-1 (PD-L1) expression in cancer and host cells, and baseline intratumoral T cell infiltration may improve response likelihood to anti-PD-1 therapies, including pembrolizumab. H...
