asthma is one of the fastest growing syndromes in many countries and is adding a huge cost to the health care system. increasing reports have linked airway infectious diseases to asthma. influenza is one of the most serious airway infectious diseases and in recent years there have been some serious influenza virus pandemics which caused increased fatality in numerous different populations. dive...

objective(s): protein kinase c (pkcα) is involved in modulating articular chondrocytes apoptosis induced by nitric oxide (no). hyaluronic acid (ha) inhibits nitric oxide-induced apoptosis of articular chondrocytes by protecting pkcα, but the mechanism remains unclear. the present study was performed to investigate the effects and mechanisms of pkcα regulate protective effect of hyaluronic acid....

objective(s): the purpose of this study was to investigate the role of chloride channel protein 2 (clc-2) in glutamate-induced apoptosis in the retinal ganglion cell line (rgc-5). materials and methods: rgc-5 cells were treated with 1 mm glutamate for 24 hr. the expression of clc-2, bax, and bcl-2 was detected by western blot analysis. cell survival and apoptosis were measured by 3-(4,5-dimethy...

background: quantification of radiation-induced apoptosis in peripheral blood lymphocytes (pbls) has been proposed as a possible screening test for cancer-prone individuals and also for the prediction of normal tissue responses after radiotherapy. materials and methods: the neutral version of the comet assay (single-cell gel electrophoresis) was used 24, 48, 72 hours after irradiation with 8 gy...

objective(s): oxidative stress has been established as a key cause of alcohol-induced hepatotoxicity. licochalcone b, an extract of licorice root, has shown antioxidative properties. this study was to investigate the effects and mechanisms of licochalcone b in ethanol-induced hepatic injury in an in vitro study. materials and methods: an in vitro model of ethanol-induced cytotoxicity in brl cel...

understanding the mechanism of tumor resistance is critical for cancer therapy. in this study, we investigated the effect of carcinoembryonic antigen (cea) overexpression on uv-and 5-fluorouracil (5-fu)-induced apoptosis and autophagy in colorectal cancer cells. we used histone deacetylase (hdac) inhibitor, nab and dna demethylating agent, 5- azacytidine (5-aza) to induce cea expression in ht29...

abstractbackground: radioprotective effects of famotidine, an antagonist of h2 receptor clinically used for peptic ulcer treatment, was previously shown on radiation-induced micronuclei and chromosomal aberration in human peripheral blood lymphocytes and mouse bone marrow cells. this study was conducted to investigate radioprotective property of famotidine against radiation induced apoptosis in...

recognition of the molecular mechanisms of camp action against dna damage-induced apoptosis can be useful to improve the efficacy of dna damaging therapeutic agents. considering the critical role of bcl-2-associated death promoter (bad) and p53 proteins in dna damage -induced apoptosis, the aim of this study was to assess the effect of camp-elevating agents on these proteins in doxorubicin-trea...
