Abstract This study aimed to determine the effects of black tea polyphenols on gene expression in hepatocellular cancer cells. The total RNA from HepG2 hepatocellular cancer cells treated with black tea polyphenols was subjected to Human 14K cDNA microarray analysis. Real-time PCR and Western blot analysis were conducted to verify microarray data. Black tea polyphenols treatment at the dose of 20 mg/L, 40 mg/L or 80 mg/L for one to three days inhibited the growth of HepG2 cells in a dose and time dependent manner. A total of 48 genes showed more than two-fold change… More >

Abstract Water contaminated with pathogenic microbes is considered as one of the most common routes for transmitting diseases in human beings. Different methods have been applied for the decontamination of microbes in contaminated water. In the current study, an easy to do hydrothermal method has been used for the preparation of TiO₂-Ag nanoparticles. The obtained material was characterised using a scanning electron microscope (SEM) and fourier transform infra-red spectroscopy (FTIR). The morphological appearance of the obtained nanoparticles was in the shape of a sphere with a size range of 60-90 nm. The antimicrobial activity of the prepared More >

Abstract Spinal muscular atrophy (SMA) is caused by dysfunction of the alpha motor neurons of the spinal cord. It is an autosomal recessive disease associated to the SMN1 gene, located in the subtelomeric region of 5q13. A paralog SMN2 gene is located at the centromeric region of the same chromosome, which apparently originated by an ancestral inverted duplication occurring only in humans. The exon sequence differs in two nucleotides in exon 7 and exon 8, which leads to an SMN2 transcript that lacks exon 7 and results in a truncated protein. Part (10%) of the SMN2… More >

Abstract Ischemic postconditioning (IP) has been shown to provide protection for ischemia/reperfusion (IR) injury, but its efficacy is limited. In this study we hypothesized that spontaneous running wheel (RW) could improve neuroprotection efficacy of IP for IR. We established mouse models of IR and showed that compared to Sham group, IR group had obvious brain infract and neurological dysfunction. In IR+IP group, brain infract and neurological dysfunction improved compared to IR group. However, in IR+IP+RW group brain infract and neurological dysfunction improved much better. TUNEL assay showed that IP but not RW significantly reduced the number… More >

Abstract In the last years, much work has shown that the most effective repair system of the body is represented by stem cells, which are defined as undifferentiated precursors that own unlimited or prolonged self-renewal ability, which also have the potential to transform themselves into various cell types through differentiation.All tissues that form the body contain many different types of somatic cells, along with stem cells that are called ‘mesenchymal stem (or stromal) cells’ (MSC). In certain circumstances, some of these MSC migrate to injured tissues to replace dead cells or to undergo differentiation to repair… More >

Abstract Pineapple leaf nanofibers (PLNFs) extracted from pineapple leaf fiber were used for reinforcing biobased polyurethane foam (BPU). The dispersion performance of PLNF in the foaming mixture system, nanocomposite foaming behavior, cell morphology, cell size, density, compressive strength and dimensional stability were investigated. The viscosity of the mixtures increased with increasing the PLNF content. The addition of a tiny amount of PLNF did not influence the exothermic temperature of the foam system, but reduced the expansion and gel time of the nanocomposite foams. This reduced time was found to increase the production efficiency. Scanning electron More >

Abstract Elm (Ulmus pumila L.) is the dominant tree species in the sparse elm woodland, the original vegetation in the Horqin Sandy Land. The effects of changes in precipitation on U. pumila trees have not been fully studied. We determined a dynamic model by considering the five stages in the U. pumila life cycle, i.e. seed, seedling, and juvenile, mature and over-mature tree stages. The effects of changes in precipitation on population density and age structure were then evaluated. Population density, after averaging all study developmental morphology stages, ranged from 16.67 individuals/m2 to 25.01 individuals/m2 under More >

Abstract Hepatitis C virus (HCV)-cirrhotic patients have the highest threat of developing hepatocellular carcinoma (HCC) and may be at risk of extra hepatic cancer. The present study was designed to investigate CD133 and CK19 in HCV (genotype-4)-cirrhotic patients with/without HCC or extra hepatic cancer, to assess the degree of their correlation with cell cycle abnormalities and finally to assess the role of their combination as diagnostic tool for discrimination of cirrhotic patients with HCC from those with extra hepatic cancer. The study included 77 HCV-cirrhotic patients and 20 healthy non-disease control group. Patients were categorized… More >
