over the years, the use of plastics has complicated the problem of disposal of solid wastes. one strategy to reduce plastic waste is the use of biodegradable plastics. a group of these plastics are polyhydroxyalkanoates (phas). to date more than 250 different microorganisms are known to synthesize and accumulate pha. most pseu-domonas strains are able to accumulate mcl-pha. in previous studies,...
an important aspect of microarray studies includes the prediction of patient survival based on their gene expression profile. to deal with the high dimensionality of this data, use of a dimension reduction procedure along with the survival prediction model is necessary. this study aimed to present a new method based on wavelet transform for survival relevant gene selection.the data included 204...
Background: VHL (von Hippel-Lindau), Runx-3 (Runt-related transcription factor 3), E-cadherin (Epithelial cadherin), P15 (INK4a, cyclin dependent kinase inhibitor), and P16 (INK4b) genes are essential in hematopoiesis. The aim of this study was to explore the correlation between gene expression and promoter methylation in CD34+ stem cells before and after differentiation to erythroid lineage. ...
conclusions expression levels of 1,426 genes were significantly up-regulated in the mutant compared to wt. furthermore, 301 genes were down-regulated with false discovery rates (fdr) of < 0.001 and absolute value of log2 ratio of ≥ 1. results a total of 4,182,944 and 4,182,021 clean tags were obtained from the wt and a nonpathogenic mutant stain (bct89), respectively, and 10,410 differentially ...
Background: Vitrification of oocytes is a fast-freezing technique, which may affect the quality of the human oocyte, and consequently affects the embryo development, pregnancy and birth. The aim of the current study was to investigate the consequence of in-vitro vitrification on maturation status of immature human oocytes, additionally, expression levels of stress, and apoptosis related genes. ...
Background & Aims: Plant extracts can change the expression of genes in cancer cells. Till now, no study has been performed on the effect of algae extract. The aim of this research was to study the changes in Bax apoptotic gene expression in glioblastoma cell line and to determine the rate of cell death in cancer cells treated with Dunalilla salina extract. U87 cell line contains glioblas...
Background: The purpose of this study was to investigate the effect of concurrent training on pre-inflammatory (IL-1β, TNF-α) and anti-inflammatory (IL-10) cytokines gene expression in women with type2 diabetes. Methods: 18-patients (age30-38, >130 glycemic index) were selected, randomly, and divided into control (n=6) the concurrent training(diabetes, n=6) and the concurrent training (healthy...
Introduction: The cancer stem cells are the small population of cells in tumor tissue with the ability of self-renew and differentiation into other tumor cells. Targeting these cells has great importance in the treatment of cancer and prevent cancer recurrence. Milk thistle is the plant of the Asteraceae with the scientific name of Silybum Marianum. However there is no report about the effect o...
In order to find out the importance of flag leaf in Hordeum vulgare L. cv. Hordea in some physiologic traits and photosynthetic and leaf senescence-related gene expression, a field experiment was carried out in Warwick University Research Farm, UK, in 2003. For more accuracy and statistical comparison of the calculated means, the experiment was carried out in 4 replicates. Random leaf samples w...
background and objectives: phosphlipases are a group of enzymes that breakdown phosphatidylcholine (phospholipids) molecules producing second products. these produced products have a divers role in the cell like signal transduction and digestion in humans. in this research the effect of phosphatidylcholine on the expression of plc genes of a. fumigatus was studied. the plc genes of this fungus ...
