گیاهان علوفه ای با تامین غذای دام، جایگاه ویژه ای در تولید پروتئین مورد نیاز انسان دارند. از جمله گیاهان علوفه ای که در ایران می تواند در جبران کمبود علوفه نقشی مهم داشته باشد، گیاه اسپرس است. ایران از مراکز تنوع اسپرس محسوب می شود و دارای ذخایر ژنتیکی ارزشمندی از این گیاه است. در بیشتر منابع علمی قابل دسترس اسپرس گیاهی دگرگشن معرفی شده ولی میزان و نحوه انجام دگرگشنی کاملا مشخص نمی باشد. شناخت ...
Jasmonic acid (JA) and salicylic acid (SA) work as a message transfer agent against biotic and abiotic stresses such as salinity. For studing the effect of JA and SA on growth, physiological and photosynthesis changes of tomato under salinity stress, a factorial experiment, based on completely randomized design, was performed in the Research Greenhouses of Isfahan University of Technology. Trea...
The compensatory growth, proximate composition and amino acid contents changes of young yellow catfish (Pelteobagrus fulvidraco R.) (1.63-1.69 g) had been investigated using a 45-day cyclic feed deprivation and re-feeding experiment. The control group (S0) was fed daily with live tubificid worms (Limnodrilus hoffmeisteri), while the S1/4, S1/2, and S1/1 groups cyclically experienced one-day of ...
بردتلا پرتوسیس باکتری گرم منفی و عامل بیماری سیاه سرفه در دستگاه تنفسی انسان است . پرتوسیس توکسین مهمترین آنتی ژن این باکتری در ایجاد پاتوژنیسیته و ایجاد محافظت بوده و زیر واحد s1 مهمترین زیرواحد این توکسین است. در این مطالعه برای بیان مهمترین زیر واحد پرتوسیس توکسین، پس از تکثیر ژن s1، وکتور های بیانی paed4 pet- 22b(+), pet-28a, pet-14b, حاوی ژن s1 به باکتری اشرشیا کلی (de3) bl21 و (plys s) b...
When 1 < p <∞, maps f in W1/p,p((0,1);S1) have W1/p,p phases φ, but the W1/p,pseminorm of φ is not controlled by the one of f . Lack of control is illustrated by “the kink”: f = eıφ, where the phase φ moves quickly from 0 to 2π. A similar situation occurs for maps f : S1 → S1, with Moebius maps playing the role of kinks. We prove that this is the only loss of control mechanism: each map f : S1 ...
Background: Animal models of psychosocial stress are a good model for studying stress-related behavioral and endocrinological disorders in humans. The aim of present study is to investigate the effect of psychosocial stress on plasma testosterone level and pain perception. Methods: In this experiment 74 male rats (200-250 g) and 20 female rats (200-300 g) were used. In experimental groups (...
this study was carried out to investigate the direct and indirect responses to selection for four-week body weight (4 week body (wk bw)) and four-week breast weight (4 week breast weight (wk brw)) and to determine the genetic contribution of reminder founders to the last generation. a total number of 351 birds were equally allocated to three lines, including two selected lines (s1 and s2 for bw...
background: s1 radiculopathy is a high prevalence illness and its early diagnosis is of crucial importance. several reports have revealed the efficacy of magnetic stimulation in diagnosis of this condition. we conducted this study to compare mmep latency and mmep amplitude in patients with s1 radiculopathy and healthy controls in shohadaye tajreash hospital in 2007. materials and methods: this ...
The dorsal premotor cortex (PMd) uses prior sensory information for motor preparation. Here, we used a conditioning-and-map approach in 11 healthy male humans (mean age 27 years) to further clarify the role of PMd in anticipatory motor control. We transiently disrupted neuronal processing in PMd, using either continuous theta burst stimulation (cTBS) at 80% (inhibitory cTBS) or 30% (sham cTBS) ...
