introduction: although pet scanning using f-18[fdg] is considered the superior radiotracer for tumnor imaging, gallium-67 is still in use for some malignancies such as lymphoma and hepatoma. one of the strategies to improve the diagnostic accuracy of gallium is to perform spect which is reported to be more sensitive compared to planar imaging. in this study we compared the sensitivity of spect ...

introduction: malignant astrocytic gliomas are the most common and lethal brain malignancies due to their refractory to the current therapies. nowadays, molecular targeted therapy has attracted great attention in treatment of glioma. connexin 43 (cx43) and micro ribonucleic acid- 21(mir-21) are among molecules that are involved in glioma development and progression. these molecules showed poten...

aluminophosphate-5 (alpo4-5) nano-pore zeolite was synthesized. the effect of alteration in precursor gel preparation on the morphology of zeolite was studied. the effect of variety of synthesis conditions on the purity, crystal and pore size, and crystallinity of alpo4-5 zeolite been studied. a hydrothermal synthesis has been used to produce nano-pore aluminophosphate-5 crystals. the crystals ...

background: mental disorders such as depression, anxiety and dementia are common in elderly. however, physical activity is suggested to be effective in preventing such aging-related disorders. the aim of this study was to investigate the role of physical activity on mental health in later life. methods: four hundred elderly people were randomly divided into the intervention and control groups. ...

For the normal linear model regression setup, Zellner’s g-prior is extended for the case where the number of predictors p exceeds the number of observations n. Exact analytical calculation of the marginal density under this prior is seen to lead to a new closed form variable selection criterion. This results are also applicable to the multivariate regression setup. AMS subject classification: P...
