abstract background: gastric cancer is a life threatening disease. recent studies have shown that rosa damascene possesses noticeable biological effects on the human body. this study, investigates the anticancer effect of rosa damascena on gastric cancer cell line mkn45. methods: microscopic studies and mtt assay were used to examine morphological alteration, and cell survival of the cancer cel...

conclusions taken together, these data reveal that cellular protease of chicken liver cells allows the replication of high yields of h9n2 virus in the absence of trypsin and also cell death in the infected cells is due to necrosis. results the degree of viability was significantly reduced in infected hepatoma cells. observations of caspase activation and cell dna laddering in infected cells wer...

Human hepatocellular carcinoma is one of the most common recurrent malignancies, for as much as, there is no effective therapy. Silibinin, a widely used drug and supplement for various liver disorders, demonstrated anticancer effects against human hepatocellular carcinoma, human prostate adenocarcinoma cells, human breast carcinoma cells, human ectocervical carcinoma cells, and human colon canc...

organotypic spinal cord slices from neonatal mammals could be a powerful model for evaluation of cell survival but also cell death mechanisms. the aim of this study was to establish an in vitro model for investigating cell survival and mechanism involved in cell death in neonatal spinal cord slices. the spinal cord was sliced and incubated into culture medium. the mtt assay was carried out to a...

background apoptosis or programmed cell death is an essential process for elimination of damaged cells. also, induction of apoptosis is fundamental for treating cancer. screening for agents that induce apoptosis in tumor cells help in the development of novel agents for cancer treatment. numerous studies suggest that the exposure of tumor cells to statins can lead to cell death via two separate...

objective(s): this study focused on determining cytotoxic effects of copper oxide nanoparticles (cuo nps) on chronic myeloid leukemia (cml) k562 cell line in a cell-specific manner and its possible mechanism of cell death. we investigated the cytotoxicity of cuo nps against k562 cell line (cancerous cell) and peripheral blood mononuclear cell (normal cell). materials and methods: the toxicity w...

Cell death is a crucial process involved in a variety of biological mechanisms controlling development, homeostasis, and immune regulation of multicellular organisms and its imbalance is associated with numerous pathologies. According to the literature, it is undeniable that the field of cell death research has been continuously growing and novel cell death modalities have been also described. ...

Apoptosis or programmed cell death is a gene regulated phenomenon which is important in both physiological and pathological conditions. It is characterized by distinct morphological features including chromatin condensation, cell and nuclear shrinkage, membrane blebbing and oligonucleosomal DNA fragmentation. Although, two major apoptotic pathways including 1) the death receptor (extrinsic) and...

fasting, that is usually described as abstinence from all food and drink for a period of time, has been experienced for ages. health, protest, religious expressions of devotion and purification are the most important reasons for fasting. many changes occur in the body during fasting including metabolic, mineral, hormonal, immunological and psychological. its use as one of the oldest therapies a...
