background: early detection is a key to survival for gastric cancer. molecular markers such as mirna (microrna) can have great importance in the early diagnosis of gastric cancer. expression of mir-21 and mir-221 are deregulated in many types of human cancers. this study aimed to investigate the differences in mirna expression patterns within the iranian population. methods: total rna was extra...

objective: mir-302-367 is a cluster of polycistronic micrornas that are exclusively expressed in embryonic stem (es) cells. the mir-302-367 promoter is functional during embryonic development but is turned off in later stages. motivated by the cancer stem cell hypothesis, we explored the potential expression of mir-302 in brain tumor cell lines. materials and methods: in the present experimenta...

Background: Stresses (such as drought, salt, viruses, and others) seriously affect plant productivity. To cope with these threats, plants express a large number of genes, including several members of ERD (early responsive to dehydration) genes to synthesize and assemble adaptive molecules. But, the function of ERD3 gene hasn’t been known so far.Objectives:</strong...

TLex is a pattern matching and parsing library for C++. In comparison to existing pattern matching tools, TLex sets a new standard for expressiveness when nearly optimal speed is required. It incorporates recent advances in regular expression technology that make it easier to write patterns and extract information from a successful match. An overview of TLex is presented, the pattern and parsin...

introduction: language impairment is a primary characteristic of children with autism spectrum disorder (asd). however, findings of language deficits in these children have been inconclusive, and many researchers believe that in such children the pattern of language profiles is different from normal children. to determine this pattern, comprehension and expression of syntax were examined in 10 ...

background : human wharton’s jelly mesenchymal stem cells (hwjmscs) express liver-specific markers such as albumin, alpha-fetoprotein, cytokeratin-19, cytokeratin-18, and glucose-6-phosphatase. therefore, they can be considered as a good source for cell replacement therapy for liver diseases. this study aimed to evaluate the effects of various culture systems on the hepatocyte-specific gene exp...

most plants encounter stress such as drought and salinity that adversely affect growth, development and crop productivity. the expression of the gene glutathione-s-transferases (gst) extends throughout various protective mechanisms in plants and allows them to adapt to unfavorable environmental conditions. gstf1 (the first phi gstfs class) gene expression patterns in the wheat cultivars mahuti ...
