هدف اصلی و اولیه این مطالعه, بهینه سازی انتقال ژن به قارچ بیماریزای گیاهی fusarium graminearum بود که عامل اصلی بیماری بلایت فوزاریومی سنبله (fhb) در غلات دانه ریز است. تراریخت کردن ژنتیکی، نه تنها ابزاری مفید جهت شناسایی ژنوم و مطالعه عملکرد آنها در بیمارگرهای گیاهی است, بلکه زمینه مطالعه برهمکنش گیاه - بیمارگر و راهکار لازم برای مقابله با بیماری را فراهم می کند. علاوه براین, تراریختی قارچ ها ...
-For the first time, different adaptive critic designs (ACDs), a conventional proportional integral derivative ( PID) regulator and backpropagation of utility are compared for the same control problem---automatic aircraft landing. The original problem proved to contain little challenge since various conventional and neural network techniques had solved it very well. After the problem had been m...
INTRODUCTION The observation that some axons, in hippocampal pyramidal neurons, emanate from dendrites rather than the somatic envelope, and the contributory synaptic input privilege (Thome et al., 2014) was highlighted as a new dimension in understanding input-output transformations (Kaifosh and Losonczy, 2014). Applying state-of-art immunocytochemical, neurophysiological, and computational me...

the effect of mdma and pentoxifylline drug on bad/bcl-xl gene dosage expression changes on rat liver
mdma generally known as ecstasy, have deleterious effects on the serotonergic neurotransmitter system. recent findings suggest that the liver and brain are major target organs of mdma-related toxicities. although most research is being dynamically performed on brain, however, the molecular mechanisms by which mdma elicits adverse effects in both organs are poorly undrestood.the present study wa...
background 3-4methylenedioxymethamphetamine (mdma) is a synthetic and psychoactive drug, which is known popularly as ecstasy and has toxic effects on human organs. objectives considering the potential toxic interaction, this study was performed to quantify the expression of bax and bcl2 genes in mdma-induced hepatotoxicity on rat liver. subsequently, we evaluated pentoxifylline as a possible pr...
rapid detection and differentiation of infectious bronchitis virus (ibv) involved in the disease outbreak is very important for controlling disease and developing new vaccines. in the present study, three regions of the genome of ibv vaccine and field isolates including s1 gene, gene 3 and nucleocapsid (n) gene along with 3' untranslated region (3' utr) were amplified and subjected to restricti...
objective: today, aids is considered as a global problem and many efforts to generate an effective vaccine against this disease have been made, but remain inconclusive. dna vaccines are a member of the new generation of vaccines that can efficiently stimulate the immune system. however, recent findings indicate low immunogenicity for these vaccines and it is believed that these types of vaccine...
objective(s) production of extended-spectrum beta-lactamases (esbls) by enteric bacteria continues to be a major problem in hospitals and community. esbls producing bacteria cause many serious infections including urinary tract infections, peritonitis, cholangitis and intra-abdominal abscess. the aim of this study was to determine the prevalence of esbls producing escherichia coli and klebsiell...
background: radiation therapy is among the most conventional cancer therapeutic modalities with effective local tumor control. however, due to the development of radio-resistance, tumor recurrence and metastasis often occur following radiation therapy. in recent years, combination of radiotherapy and gene therapy has been suggested to overcome this problem. the aim of the current study was to e...
