هدف:جداسازی و تایید تشخیص یک مورد عفونت ویروسی در سگ با پاروویروس. طرح: مطالعه موردی. تاریخچه: سگ نر 7 ماهه ای از نژاد مخلوط با علایم استفراغ، اسهال و بی اشتهایی به درمانگاه دامهای کوچک دانشکده دامپزشکی دانشگاه تهران ارجاع داده شد. در معاینه بالینی دهیدراتاسیون شدید، حضور خون در مدفوع و در شمارش سلولهای خونی کاهش شدید تعداد WBC ( I ? / 500 ) جلب توجه نمود. نمونه مدفوع در آزمون تشخیص پادگنی ای...
Lung cancer is a complex disease that often manifests at the point when treatment is not effective. Introduction of blood-based complementary diagnostics using molecular markers may enhance early detection of this disease and help reduce the burden of lung cancer. Here we evaluated the diagnostic potential of seven plasma miRNA biomarkers (miR-21, -19b, -126, -25, -205, -183, -125b) by quantita...
We analyze full-orbit phase curve observations of the transiting hot Jupiters WASP-19b and HATP-7b at 3.6 and 4.5 μm obtained using the Spitzer Space Telescope. For WASP-19b, we measure secondary eclipse depths of 0.485% ± 0.024% and 0.584% ± 0.029% at 3.6 and 4.5 μm, which are consistent with a single blackbody with effective temperature 2372 ± 60 K. The measured 3.6 and 4.5 μm secondary eclip...
The reaction of the 2-(4-oxo-4,4-dihydrothiazol-2-yl)acetonitrile 1 with cyaclopentanone (2) afforded the condensed product 3. The latter underwent a series of heterocyclizations through its reaction with different reagents. Moreover, compound 1 underwent the Gewald’s thiophene to afford compounds 15 and 17. The reaction of either hydrazine hydrate or phenylhydrazine with compound 17 gave the h...
Gene expression in lambdoid phages in part is controlled by transcription antitermination. For most lambdoid phages, maximal expression of delayed early genes requires an RNA polymerase modified by the phage N and host Nus proteins at RNA NUT sites. The NUT sites (NUTL and NUTR) are made up of three elements: BOXA, BOXB and an intervening spacer sequence. We report on N antitermination in H-19B...
The effects of naringin on the expression of miR-19b and cell apoptosis were investigated in the human hepatocellular carcinoma cell line HepG2. HepG2 cells were treated with varied concentrations of naringin. The effects of naringin on the proliferation of HepG2 cells were observed by an MTT assay, morphological changes of cells were observed by an inverted microscope, cell apoptosis was detec...
Shiga toxin (Stx) genes in Stx producing Escherichia coli (STEC) are encoded in prophages of the lambda family, such as H-19B. The subpopulation of STEC lysogens with induced prophages has been postulated to contribute significantly to Stx production and release. To study induced STEC, we developed a selectable in vivo expression technology, SIVET, a reporter system adapted from the RIVET syste...

Gastric cancer (GC) is the second most common cancer in China and the second leading cause of cancer-related death in the world. Identifying circulating biomarkers is helpful to improve theranostics of gastric cancer. Herein, we are for the first time to report miR-16-5p and miR-19b-3p were identified to be the novel potential plasma biomarkers to detect gastric cancer. Differentially expressed...
