Emerging evidences have indicated that long non-coding RNAs (lncRNAs) are pivotal regulators of tumor development and progression. HNF1A-AS1 (HNF1A antisense RNA 1, C12 or f27) is a novel long non-coding RNA that acts as a potential biomarker and is involved in development and progression of several cancers. Nevertheless, we know nothing about the clinical significance and molecular mechanism o...

Plant B-BOX (BBX) zinc finger transcription factors play crucial roles in growth and development the stress response. Although BBX family has been characterized various plants, systematic analysis watermelon is still lacking. In this study, 25 ClBBX genes were identified. ClBBXs grouped into five clades (Clade I, II, III, IV, V) based on their conserved domains phylogenetic relationships. Most ...

Abstract This work aims to experimentally investigate the influence of screw elements on dispersion Cloisite-15A in vinyl ester based design experiments using MINITAB-V16 software. Experiments were designed considering two main factors such as loading (1, 2, 3, and 4 wt%) type with a varying number kneading (type 1 55 mm, 2 90 elements). The procedure was carried out by combination both ultraso...

Cloisite Na+was used as a solid surfactant (stabilizer) in Pickering emulsion polymerization of styrene-co-butyl acrylate in presence of oil soluble initiator, azobisisobutyronitrile (AIBN) and water soluble initiator, potassium persulfate (KPS). Fourier transform infrared (FTIR) spectrum approved the corporation of Cloisite Na+ layers within the polymer matrix. Effect of clay content was a...

PURPOSE To evaluate the expression of microRNAs in tissue samples from patients with bladder cancer and to compare it with healthy adjacent tissue samples as controls. MATERIALS AND METHODS Thirty five tissue samples from patients with newly diagnosed untreated bladder transitional cell carcinoma and 35 adjacent normal urothelium were collected during 2013 to 2014. TRIzol reagent was used to ...

Comparison of microRNA (miRNA) expression profiles in the noncancerous liver tissues adjacent to hepatocelluar carcinomas (HCCs) was a strategy to identify postoperative prognostic predictors in this study. Expression profiles of 270 miRNAs were determined in the paraneoplastic liver tissues of 12 HCC patients with known postoperative prognosis. A panel of candidate miRNA predictors was identif...
