Purpose Mutations in rod photoreceptor genes can cause retinitis pigmentosa (RP). Rod gene expression is regulated by the nuclear hormone receptor, Nr2e3. Genetic deletion of Nr2e3 reprograms rods into cells that resemble cone photoreceptors, and might therefore prevent their death from some forms of RP. There are no identified ligands for Nr2e3; however, reverse agonists might mimic the geneti...

با توجه به میزان خسارت ناشی از بیماری های قارچی، استفاده از تکنیک های بیوتکنولوژی برای تولید گیاهان مقاوم، از اهمیت ویژه ای برخوردار است. بیان ترکیبی از پروتئین های مرتبط با بیماری زایی منجر به القاء مقاومت چندژنی می شود که از یک سو پایداری مقاومت را به همراه داشته و از سویی دیگر باعث مقاومت به طیف وسیعی از قارچ های بیماری زا می گردد. لذا این تحقیق با هدف انتقال سازه های پلاسمیدی چندگانه، حاوی ...

i ntroduction:   the  trigeminocardiac  reflex  (tcr)  refers  to  the  sudden development of bradycardia as well as asystole along with arterial hypotension associated with any manipulation of sensory branches of the trigeminal nerve. clinically, the tcr has been reported to occur during craniofacial surgery. it is crucial to learn about this sudden physiological response during maxillofacial ...

Pseudozyma spp. are yeast-like fungi, classified in the Ustilaginales, which are mostly epiphytic or saprophytic and are not pathogenic to plants. Several Pseudozyma species have been reported to exhibit biological activity against powdery mildews. However, previous studies have reported that Pseudozyma aphidis, which can colonize plant surfaces, is not associated with the collapse of powdery m...

This paper describes reactive transport simulations conducted to assess the impact of mineral fouling on the hydraulic behavior of continuous-wall permeable reactive barriers (PRBs) employing granular zero-valent iron (ZVI) in carbonate-rich alluvial aquifers. The reactive transport model included a geochemical algorithm for simulating corrosion and mineral precipitation reactions that have bee...

The blockade of epidermal growth factor receptor (EGFR) function with monoclonal antibodies has major antiproliferative effects against human tumors in vivo. Similar antiproliferative effects against some of these same tumors have also been observed with specific inhibitors of the EGFR-associated tyrosine kinase. One such inhibitor, the p.o. active ZD1839 (Iressa), has pronounced antiproliferat...

Fourteen cDNA clones of pathogenesis-related (PR) proteins, PR1a and PR1b of tobacco were obtained and classified into six groups based on restriction enzyme maps. To assign the groups to different classes of PR1 proteins, all the clones were partially sequenced and compared with amino acid sequences of PR1a and PR1b. Two groups of these corresponded to PR1a and four to PR1b. The results indica...
