background the current distribution of and access to health services along with the future health needs of the population have prompted wide application of geographic information systems (giss). during recent years, gis has been used in public health management for planning and organization of healthcare services. this study investigates geographical accessibility of residential areas in bandar...
وارونوشتاز مقاوم به دما (trt ) اهمیت زیادی جهت تولید cdna دارد. ژن trt با توانایی تولید این آنزیم، از باکتری geobacillus stearothermophilus strain10 استخراج و توسط حامل بیانی pet28-a در میزبان escherichie coli کلون شد و شرایط رشد این میزبان هترولوگ مورد بهینه سازی قرار گرفت. زیست توده ها جمع آوری شد.عصاره سلولی تهیه، آنزیم مورد نظر تخلیص و غلظت پروتئینی آن سنجیده شد. وارونوشتاز حاصل، جهت rt-pcr...
This paper presents the design of RT-Appia, a framework for the development and implementation of configurable real-time protocol stacks. The goal of RT-Appia is to allow the construction of specialized protocols through the composition of pre-defined micro-protocols. RT-Appia attempts to balance the flexibility and efficiency of micro-protocols with the predictability requirements of real-time...
چکیده از آنجا که محتوای ملانین در سلول های rpe افراد بالغ و نوزاد و همچنین بین پاساژهای مختلف سلولی در شرایط معمولی محیط کشت متفاوت می باشد در این مطالعه ژن های اصلی در مسیر سنتز ملانین، mitf-a، mitf-h، mitf-d و otx2 به عنوان فاکتورهای مهم رونویسی و تیروزیناز (tyr) و دوپاکروم تاتومراز (dct) به عنوان آنزیم های موثر در مسیر سنتز ملانین بررسی شدند. در ابتدا سلول های rpe از گلوب های چشم انسان های ...
the quality of the communication between teachers and students and ultimately, of classroom education itself, is closely linked to the acoustic quality of the auditorium. this acoustic quality can be characterized based on the reverberation time (rt), speech transmission index (sti) and the sound insulation. in this context, an acoustic study was conducted in an auditorium located in the higher...
A variety of factors that influence real-time reverse transcriptase (RT)-PCR results were examined. Realtime reaction volumes can be decreased from the manufacturers suggested volumes (50μl) to as little as 5μl. Errors introduced through volume handlings can be significantly mitigated through the use of electronic pipettes. Random hexamers are compared against the use of a specific reverse tran...
conclusions the analysis of the pro-apoptotic gene to anti-apoptotic gene expression ratio (bad /bcl-xl) confirmed that expression of the pro-apoptotic gene significantly decreased (p value ˂ 0.001) under the ischemia/reperfusion condition. in contrast, the expression of the anti-apoptotic gene increased after administration of fk-506 (p value ˂ 0.001). results the quantitative results of real-...
background: breast cancer is the most common cancer in women. non-coding rnasespecially mirnas have important regulatory roles in cancer. mirnas are 21-24 nucleotides which have different levels of expression between tumors and normal tissues. in this study, we have analyzed expression level of mir-520d in three different groups of breast cancer. methods: fifty nine samples were divided into di...
background and aims: accurate and rapid diagnosis is necessary for effective control and prevention of foot-and-mouth disease (fmd). in present study, was evaluated real time reverse transcription-polymerase chain reaction (rrt-pcr) assay along with diagnostic routine methods for the detection of all seven serotypes of fmd virus (fmdv), namely o, c, a, sat1, 2, 3 and asia 1 in biological sample...
