Fibrosis results when myofibroblasts invade the wound fibrin provisional matrix. Extracellular matrix receptors on the cell surface mediate cell adhesion, migration, and invasion. Recent work with transformed cells indicates that these cells use the cell surface matrix receptor CD44 for migration and invasion. In this study, we examine whether lung fibroblasts, isolated from patients dying with...

background: bleomycin (blm) is an anti-cancer drug widely used in the treatment of cancer. blm causes several side effects related to dna and cellular damage. the aim of this study was investigated the effects of tea polyphenol epicatechin on anti-proliferative effects induced by bleomycin in human normal skin and human ovarian cancer cells.materials and methods: human ovarian cancer cell (skov...

background: the aim of this study was to investigate the effect of methanolic extract of achillea millefolium l. (mea) on the antiproliferative activity of bleomycin on human prostate cancer and normal skin cells. materials and methods: human prostate cancer cell (du-145) and human non-malignant fibroblast cell (hfff2) were treated with mea at various concentrations ( 20, 100, 500, 1000 and 200...

The utilization of natural extracts as an ingredient in cosmetic products becomes a better choice for customers. Rice berry has been defined potential source anti-free radical properties which is able to be formulated products. Therefore, the objectives this study are 1) investigate antioxidant by ABTS and assays, total compounds phenolic flavonoids cell viability fibroblast NIH3T3 (IC80) ethan...

This study aimed to investigate the phenolic content, antioxidant activity, cytotoxicity and in vitro wound healing activity of methanolic aqueous extracts Verbascum stachydifolium Boiss & Heldr. var. stachydifolium. Total flavonoid contents were measured using spectrophotometry-based methods. Quantitative analysis selected phenolics was performed by HPLC. The cytotoxic effects on L929 mous...

objective(s): to improve water stability of electrospun chitosan/ polyethylene oxide (peo) nanofibers, genipin, a biocompatible and nontoxic agent, was used to crosslink chitosan based nanofibers.  materials and methods: different amounts of genipin were added to the chitosan/peo solutions, chitosan/peo weight ratio 90/10 in 80 % acetic acid, and the solutions were then electrospun to form nano...

Abbreviations: Ad: adenovirus, bFGF: basic fibroblast growth factor, BMP: bone morphogenetic protein, CNS: central nervous system, ES: embryonic stem, FACS: fluorescence activated cell sorting, HIV: human immunodeficiency virus, ICM: inner cell mass, LIF: leukemia inhibitory factor, MEF: mouse embryonic fibroblast, RNAi: RNA interference, SCNT: somatic cell nucleus transfer, UTR: untranslated r...

We investigated the susceptibility to Usutu virus (Flavivirus) of 13 permanent cell lines, 3 primary cell cultures, and chicken embryos. Vero, PK-15, and goose embryo fibroblast cells developed cytopathic effects; however, viral multiplication was detected in all mammalian cell types by immunohistochemical tests. Chicken embryo fibroblast cells and chicken embryos were resistant.

marine streptomyces are prolific producers of majority of bioactive secondary metabolites which are used in pharmaceutical industry as effective drugs against life threatening diseases. the cytotoxic activity of the pure compound 1, 2- benzene dicarboxylic acid, mono 2- ethylhexyl ester (dmehe) from marine derived actinomycete streptomyces sp. vitsjk8 was investigated against mouse embryonic fi...

Environmental microplastics exist at sub-micrometer sizes (nanoplastics, NPs) as they continue to disintegrate over time. Although concerns regarding harm human health are growing, data on the effects of NPs skin lacking. Therefore, this study sought investigate whether penetrate and affect physiology cells Different sized polystyrene (0.2, 0.5, 1.0 μm) (approximately sub-micron level) tagged w...
