background: considering that cannabinoids protect neurons against neurodegeneration, in this study, the neuroprotective effect of win55,212-2 in paraoxon induced neurotoxicity in pc12 cells and the role of the n-methyl-d-aspartate (nmda) receptor were evaluated. materials and methods: in this study pc12 cells were maintained in dulbecco's modified eagle’s medium (dmem+f12) culture medium supple...

AIM To investigate whether the hypoxia-inducible factor-1α (HIF-1α) genetic variants and protein expression affect the chemotherapy response and the clinical outcome of patients with advanced non-small cell lung cancer (NSCLC). METHODS A total of 741 patients with histologically confirmed advanced NSCLC were recruited. Two polymorphisms of HIF-1α gene, namely, the C1772T (P582S) and G1790A (A...

Harris argues that if QALYs are used only 50% of the population will be eligible for survival, whereas if random methods of allocation are used 100% will be eligible. We argue that this involves an equivocation in the use of "eligible", and provides no support for the random method. There is no advantage in having a 100% chance of being "eligible" for survival behind a veil of ignorance if you ...

Background: We explored survival of skin cancer and its determinants in Kurdistan province of Iran. Methods: In a retrospective cohort design, we identified all registered skin cancer patients in Kurdistan Cancer Registry from year 2000 to 2009. Information on time and cause of death were obtained from Registrar’s office and information on type, stage and anatomic locations were extracted fr...

Background and Aim: This study aimed to indicate the role of epidermal growth factor (EGF) in proliferation and growth of epithelial tissue and to determine the correlation be-tween the frequency of expression of EGF receptor (EGFR) by means of immunohistochemistry with survival rate in oral squamous cell carcinoma (OSCC). Materials and Methods: Thirty-eight cases of OSCC diagnosed by hemato...

conclusions despite the fact that abnormalities in p53 and p27kip1 may be involved in the development of oscc, their clinical significance in the studied population seems limited. further investigation on the combined p53/p27kip1 expression may be helpful in predicting the biologic behavior of this tumor. results p53 and p27kip1 expression were found in 28.57% (8 positive versus 20 negative) an...
