A fourth-generation Ziegler-Natta catalyst was prepared to synthesize polypropylene (PP), which was stabilized by in situpolymerization employing lignin as antioxidant. The antioxidant properties of lignin were compared with those of the commercial antioxidant Irganox 1010. The presence of lignin in the reaction medium slightly decreased the catalytic activity of the reaction. The isotacticity ...

MicroRNAs (miRNAs/miRs) play crucial roles in cancer development and progression. The purposes of this study were to investigate the role of miR-187 in osteosarcoma and clarify the regulation of MAPK12 by miR-187. Quantitative polymerase chain reaction was used to examine miR-187 expression in osteosarcoma tissues and cell lines. The clinicopathological significance of miR-187 downregulation wa...

Background: Literature review shows that there are not sufficient data about polyphenolic compounds of peel of Iranian pomegranate. So, this work was mainlyundertaken to determine phenolic compounds and antioxidant activity of dried peel of Iranian pomegranate. Methods: Pomegranate fruits were obtained from mature fruits grown in Saveh, Iran and the Pomegranate Peel (PP) were dried with three ...

Aberrantly expressed microRNAs contribute to the initiation and progression of human cancer. MiRNA-187 has been reported in nasopharyngeal, renal, pancreatic, prostate, and esophageal cancer, and acts as a tumor suppressor or oncogene. However, the underlying function of miRNA-187 in cervical cancer remains largely unexplored. In the present study, we demonstrated significantly miRNA-187 down-r...

We modelled language-learning processes in a brain-inspired model of the language cortex. The network consisted of neuron-like elements (graded-response units) and mimicked the neuroanatomical areas in the perisylvian language cortex and the intrinsic and mutual connections within and between them. Speaking words creates correlated activity in motor and auditory cortical systems. This correlate...

Viruses are responsible for 4 to 50% destruction of bacterial and archaeal communities (Breitbart and Rohwer, 2005; Rohwer and Thurber, 2009) and the selective pressures imposed by these rapidly evolving viruses (parasites) has driven the diversification of microbial defence systems. Previously our understanding of antiviral immune systems in bacteria has focused on encounter blocks, adsorption...
