Skin photodamage, which is induced by ultraviolet (UV) radiation, a prevalent cause of skin damage. In this study, transdermal drug delivery system developed for the topical treatment composed tetrahedral framework nucleic acids (tFNAs) and lipoic acid (LA). The tFNAs-LA (TLA) nanocomposite exhibits excellent biocompatibility, as well antioxidant, anti-apoptotic, anti-inflammatory capabilities....

artemisia is an important genus of iranian flora whose potent anti-proliferative effect has been demonstrated previously on human cancerous cell lines. in the current study, further fractionation was carried out on the petroleum ether extract of a. aucheri and their cytotoxic effects were evaluated on three human cancer cell lines. cell viability was determined by 3-(4,5-dimethylthiazol-2yl)-2,...

Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL), a member of TNF family, is an interesting ligand which selectively induces apoptosis in tumor cells and, therefore, it has been developed for cancer therapy. This ligand has been produced by various hosts such as E.coli. However, protein expression in E.coli cytoplasm leads to problems such as incorrect folding, reduction in biolo...

objective we have previously shown that rose bengal (rb) alone, not as a photosensitiser, could induce apoptotic- and non-apoptotic cell death in different melanoma cell lines. to clarify rb-induced toxicity mechanisms, role of caspases and reactive oxygen specious (ros) were studied in melanoma cells. material and methods human melanoma cell lines, me 4405 and sk-mel-28 were cultured in dmem m...

Background Oleanolic acid (OA) has notable anti-inflammatory and anti-tumor effects, but the role of OA in cerebral ischemia-reperfusion injury (CIRI) not been reported so far. Methods Oxygen glucose deprivation/reoxygenation (OGD/R) model was induced PC12 cells. MTT assay used to detect cell viability cells, while ELISA detected expression TNF-?, IL-1? IL-6. The superoxide dismutase (SOD), mal...

Background & objective: The current study aimed to perform an immunohistochemical analysis of patterns of apoptotic and cell proliferative related protein expression in different histological grades and immune phenotypes of malignant lymphomas and other lymphoproliferative disorders Methods:This observational study was carried o...

Background: While mammalian embryos can adapt to their environments, their sensitivity overshadows their adaptability in suboptimal in vitro conditions. Therefore, the environment in which the gametes are fertilized or to which the embryo is exposed can greatly affect the quality of the embryo and consequently its implantation potential. Objectives:</stro...

Purpose: To investigate the effect of resveratrol (RSV) on bortezomib (BTZ)-resistant multiple myeloma (MM) cells, and to elucidate underlying mechanism action.&#x0D; Methods: H929 cell lines were exposed BTZ for 8 months establish BTZ-resistant MM model. Cell proliferation was determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Apoptosis measured using annex...
