گوشت یک منبع پروتئین عالی و مغذی محسوب میشود اما بهعلت قیمت بالای این پروتئین حیوانی و دستیابی به سود اقتصادی بیشتر توسط برخی تولیدکنندگان، اغلب در فرآوردههای گوشتی، تقلباتی نظیر استفاده از گونههای گوشتی با ارزش تجاری کمتر، مورد توجه است. در این تحقیق سعی شده تا پروتئین ارزان قیمتی نظیر گوشت مرغ که بهطور معمول در همبرگرهای ممتاز ایرانی استفاده نمیشود اما امکان این تقلب وجود د...
A new family of duplex-forming recognition encoded oligomers, capable sequence selective duplex formation and template directed synthesis, was developed. Monomers equipped with both amine aldehyde groups were functionalized...
The DNA duplex corresponding to the entire length (126 nucleotides) of the precursor for an Escherichia coli tyrosine tRNA has been synthesized. Duplex [I] (Sekiya, T., Besmer, P., Takeya, T., and Khorana, H. G.(1976) J. Biol. Chem. 251, 634-641), corresponding to the nucleotide sequence 1-26, containing single-stranded ends and carrying one appropriately labeled 5'-phosphate group, was joined ...
In this paper, full-duplex radios are used to continuously update the channel state information at the transmitter, which is required to compute the downlink precoding matrix in MIMO broadcast channels. The full-duplex operation allows leveraging channel reciprocity for open-loop uplink training to estimate the downlink channels. However, the uplink transmission of training creates interference...
Renal pelvis urothelial carcinoma of the upper moiety in complete right renal duplex: a case report.
Urothelial carcinoma (UC) originated from renal pelvis is the common tumor of the urinary system, however, neoplasia of the renal pelvis in duplex kidneys is extremely rare, especially in the complete renal and ureteral duplex cases. We present the first case of renal pelvis UC of the upper moiety in a complete right renal duplex. This male patient has bilateral complete renal and ureteral dupl...
recA protein promotes the homologous pairing of single strands with duplex DNA by polymerizing on the single strands to make presynaptic nucleoprotein filaments which are polyvalent with respect to duplex DNA and which consequently form large networks or coaggregates when duplex DNA is added. Previous work has shown that efficient homologous pairing occurs within these networks. In the experime...
response modification factor (r-factor) is one of the seismic design parameters to consider nonlinear performance of building structures during strong earthquake. relying on this, many seismic design codes led to reduce earthquake loads imposed to the structure. the present paper tries to evaluate the r-factors of conventional concentric braced frames (cbfs) and special moment frames (mrfs) in ...
Backgrounds: There are controversies among surgeons about prophylaxis of deep vein thrombosis (DVT) in laparoscopic cholecystectomy. The aim of this study was the assessment of patients’ condition after laparoscopic cholecystectomy without any prophylactic measure. Methods: 100 cases of laparoscopic cholecystectomy without DVT prophylaxis were followed by duplex scanning in the first postopera...
INTRODUCTION The gold standard for evaluation of the lower extremity arterial tree is catheter angiography. Duplex arterial-occlusive imaging or duplex ultrasonography arteriography, a noninvasive technique, is used as the first-line investigation in patients with peripheral vascular disease at our centre. Based on the results of duplex imaging, patients who require angiographic intervention th...
