Background: The MET receptor is a critical member of cancer-associated RTKs and plays an important role in different biological activities, including differentiation, migration, and cell proliferation. Methods: In this study, novel MET inhibitors were introduced and applied on esophageal squamous carcinoma cell line KYSE-30, and the level of proliferation and migration, as well as the activated...
امروزه با توسعه روز افزون تکنولوژی mems و کاربردهای گسترده آن در مهندسی پزشکی می توان قطعاتی را طراحی نمود که قابل کاشت (implantable ) در داخل بدن باشد. اندازه گیری مقدار قند خون یکی از زمینه هایی می باشد که با توسعه تکنولوژی memsمورد توجه بوده است. در بیماران دیابتی نوع دوم، میزان قند خون بالا می باشد و از آنجایی که با افزایش قند خون احتمال بیهوشی نیز بالا می رود، لذا اندازه گیری قند خون بصورت...
quinazolinones are a group of fused heterocyclic compounds which have valuable biological properties including cytotoxic, antibacterial and antifungal activities. thiazole group-containing compounds have been also reported to have a wide range of biological activities such as antitumor, anti-inflammatory, analgesic and antibacterial effects. due to valuable cytotoxic effects of both thiazole gr...
Background: Biosynthesis of nanoparticles has attracted the attention of the scientific community in nanotechnology and biotechnology due to their extensive application in the area of material sciences and medicine. Nowadays, despite a various application of nanomaterial’s, there is a little information about their impact on human health. In this study, we investigated the comparative study on ...
signal transducers and activators of transcription (stats) are cytoplasmic transcription factors that have a key role in cell fate. stats, a protein family comprised of seven members, are proteins which are latent cytoplasmic transcription factors that convey signals from the cell surface to the nucleus through activation by cytokines and growth factors. the signaling pathways have diverse biol...
background and objectives: contamination of cell lines and biological products is one of the major problems of cell culture techniques. rapid detection of mycoplasma contamination in cell culture is an important part of quality control standards in related laboratories. the aim of this study was to evaluate the efficacy of pcr in detection of myroplasma as contaminants in cell cultures and othe...
this thesis aims at putting together two of the vestest areas of study there is in humanities: bioethics and literature. the two novels in question, oryx and crake and the year of the flood, are considered as some of the most succssful examples of spculative fiction. in these novels the biological and environmental issues raised as looked at from a bioethics point of view.
Researchers in bioelectromagnetics often require realistic tissue, cellular and sub-cellular geometry models for their simulations. However, biological shapes are often extremely irregular, while conventional geometrical modeling tools on the market cannot meet the demand for fast and efficient construction of irregular geometries. We have designed a free, user-friendly tool in MATLAB that comb...
improving the solubility of non-soluble herbal materials is an issue of interest in cell culture based experiments. evaluating the biological activity of these materials could become possible with the aid of cosolvents/surfactants which obviously should have little or no cytotoxic activity. in the present study, the cytotoxic activity of six cosolvents/surfactants: ethanol, methanol, tween 20 a...
