In the present paper we consider Cauchy-type problem associated to space-time fractional differential equation \begin{document}$ \partial_t u+\partial_t^{\beta}(-\Delta)^{1-\beta}u-\Delta u = g(t, x), \quad t>0, \ x\in \mathbb R^n $\end{document} with $ \beta\in (0, 1) $, where derivative \partial_t^{\beta} is in Caputo sense and (-\Delta)^{1-\beta} Laplace operator of order 1-\beta $. We pr...

زنگ زرد گندم توسط قارچ puccinia striiformis westend f.sp.tritici ایجاد می شود و از عوامل عمده کاهش دهنده عملکرد کمی و کیفی گندم بویژه در مناطق سرد و مرطوب می باشد. در این مطالعه تغییرات ساختاری و تنوع نوکلئوتیدی برخی از ژن های مقاومت به زنگ زرد در هفت ژنوتیپ گندم نان با درجات متفاوت مقاومت به زنگ زرد بررسی شد. ژن های مقاومت به زنگ زرد با استفاده از آغازگرهای اختصاصی طراحی شده بر اساس توالی های ...

Background: Normal tissue toxicity continues to remain as a major challenge for radiation oncologists for delivering the total dose to the tumour cells in cancer patients. Cellular, molecular and plasma based early biomarkers to predict the overreactions and non-overreactions of normal tissue toxicity before the initiation of radiotherapy can be valuable for personalised treatment. The aim of t...

Background: Transforming growth factor-β1 (TGF-β1) has been found to play a crucial role in early central nervous system development. Several studies have illustrated decreased TGF-β1 levels in sera and brains of autistic children. Two point mutations in the TGF-β1 signal peptide at 869T/C and 915G/C have been reported to influence TGF-β1 expression. The aim of the pres...

Introduction: In order to study the alterations of beta 1 and 2 integrins mRNA level in rat lumbar spinal cord following the induction of chronic pain and its effect on the development of tolerance to morphine analgesia, we examined the level of expression of these genes in the presence of chronic pain, which is an inhibitor of morphine tolerance. We used induction of chronic pain alone and ...
