هدف: این مطالعه به منظور بررسی ارتباط میان علائم بیماران و stage کارسینوم معده در بیماران مراجعه کننده به بیمارستان امیرالمومنین تهران طی سالهای 90-89 انجام شده است. روش مطالعه: در این مطالعه مقطعی، 30 فرد مبتلا به سرطان معده بررسی شدند که افراد از نظر staging بررسی شده و stage آنها ثبت گردید و در نهایت فراوانی علائم بالینی مختلف در stageهای مختلف مورد مقایسه قرار گرفت. یافته ها: 7/6 درصد در ...
A greenhouse factorial experiment was conducted in completely randomized design (CRD) with three replications to investigate the effect of soil Zn deficiency stress on the expression of three genes involved in the synthesis of metal chelating agents (NAS1, NAS2 and NAS3) in bread wheat. Hamoun and Hirmand (Zn-efficient and inefficient cultivars, respectively) cultivars were planted under Zn def...
In order to evaluate the effect of plant growth-promoting rhizobacteria) PGPR( on salt tolerance in vegetative and reproductive growth stages of safflower (Carthamus tinctorius), a randomized complete block design with a factorial combination of bacterial inoculation and salinity, each in three levels, and four replications was conducted in experimental glasshouse of Vali-e-Asr University of Ra...
Leaf rust (caused by Erikss. []) is increasingly impacting durum wheat ( L. var. ) production with the recent appearance of races with virulence to widely grown cultivars in many durum producing areas worldwide. A highly virulent race on durum wheat was recently detected in Kansas. This race may spread to the northern Great Plains, where most of the US durum wheat is produced. The objective of ...
this research was carried on in order to investigate the response of wheat cultivars to salinity tension as factorial experiment and in complete randomized block design in four replications in islamic azad university shoushtar branch. in this experiment the response of nine wheat cultivars including chamran, karchia66, mahoti, roshan, alvand, kavir, ghods, atrak and tjan at vegetative growth st...
To evaluate the physiological responses of chrysanthemum to silicon spray in non-stress conditions, this study was performed in two separate experiments (at 4 to 5 and 8 to 12-leaf stages) as a factorial randomized completely design with two factors: silicon source (in two levels: sodium silicate and calcium silicate) and the concentration of silicate at five levels (0, 50, 100, 150 and 200 mg ...
مقدمه: امروزه سرطان پوست جزء شایعترین سرطان ها ست، بررسی های انجام شده حکایت از شیوع بالای آن دارد و تعداد مبتلایان به آن روز به روز در حال افزایش است. ملانوما نادرترین و بدخیم ترین نوع سرطان پوست می باشد که از سلول های رنگدانه ای پوست به نام ملانوسیت منشا می گیرد.ملانوما در شرایط پیشرفته توانایی انتشار به ارگان های داخلی را دارد و می تواند منجر به مرگ شود اما در صورتیکه در مراحل اولیه تشخیص دا...
Green semilooper, Naranga aenescens Moore (Lepidoptera: Noctuidae) is a major pest in paddy fields of northern Iran. Since plant resistance to pests is a method with high efficacy and safety, a research was conducted to evaluate the resistance of 12 rice varieties (including, Tarom, Shafagh, Hybrid, Khazar, Poya, Fajr, Kados, Shiroodi, Sahel, Tabesh, Nemat and Neda) to N. aenescens on the basis...
in order to study of nitrogen application time and seed inoculation with plant growth promotingrhizobacteria on yield, fertilizer use efficiency and grain filling rate of sunflower, a factorial experimentwas conducted based on randomized complete block design with three replications in research farm ofislamic azad university, ardabil branch in 2011. the first factor was time of nitrogen applica...
Rapid screening of plant germplasm in the early stages of growth and determining the genetic basis of wheat leaf wilting index at the seedling stage is necessary for wheat breeding programs. In the present research, leaf wilting index for 290 Iranian bread wheat genotypes, including; 90 cultivars and 200 landraces were studied under drought stress conditions at the seedling stage in 2021 in res...
