the extent to which written corrective feedback on linguistic errors can play a role in helping l2 writers improve the accuracy of their writing continues to be an issue of interest to researchers and teachers since truscott (1996) mounted a case for its abolition. while there is growing empirical evidence that written corrective feedback can successfully target some types of linguistic error (...
Breast cancer is a complex genetic disease that has an average annual incidence of two million people and the second leading cause of death among women all over the world. Micro-RNAs are consistently reported to regulate gene expression in all cancers. The present study, the correlation between the expression of hsa-miR-490-5p and nuclear factor of activated T-cells 5 (NFAT5) in breast cancer w...
Background and purpose: Hepatitis B virus (HBV) is a major global health problem. The prevalence of HBV infection varies throughout regions of the world. More than 350 million people live with chronic HBV infection and many different clinical symptoms are associated with it. Long-term complications of HBV infection lead to cirrhosis of the liver and hepatocellular carcinoma. Consequently, 0.5-1...
Here for the first time, we investigated the cytotoxic effects of the chitosan extracted from the Persian Gulf Chiton shell (Acanthopleura vaillantii) on liver cancer cell line (HepG2). Chitosan extraction was implemented following this method: chitin was produced by demineralization and deproteinization procedure, and the extracted chitin was converted into soluble chitosan using deacetylation...
The present study examined the antioxidant defense of glutamine on plasma and liver antioxidant status in broilers under PHS with respect to changes in the levels of lipid peroxidation marker malondialdehyde (MDA), total antioxidant status (TAS) and the activities of anti peroxidative enzymes [superoxide dismutase (SOD) and glutathione dependent antioxidant enzymes glutathione peroxidase (GPX)]...
Free-living and particle-associated bacterial communities in the Chesapeake Bay estuary were analyzed and compared by using acridine orange direct counts and low-molecular-weight (LMW) RNA analysis. Samples were taken from top and bottom waters at upper- and mid-bay sites in December 1992. Free-living bacteria dominated the bacterial numbers at all sampling sites, although particle-associated b...
Background & Objective: Liver biopsy is the main method for grading and staging liver disorders, but the effects of clinical information and optimal biopsy specimen size on interpretation remain contentious. The aim of the study was to evaluate the impact of clinical information and quality of liver specimen on inter-observer agreement for liver disease. Methods:<...
Background: Aberrant pre-mRNA alternative splicing is a common event in cancer cells. Many abnormally spliced RNA variants have been observed in tumor cells and they can be used as biomarkers or therapeutic targets in new drug design. Increasing our knowledge in understanding the mechanisms of alternative pre-mRNA splicing for cancer-related genes and determination of cancer specific isoforms a...
MicroRNAs are non-coding RNAs that negatively regulate mRNA expression and play significant roles in both health and disease. Differential microRNA expression has been used to aid diagnosis and discriminate disease stages. The accuracy and reliability of microRNA expression measurement is of utmost importance. Quantification of microRNA expression in human peripheral blood is commonly detected ...
