background identification of a normal range for biomarkers, based on pregnancy outcomes (caused by their high or low values) is of special importance in clinical studies. as some pregnancy outcomes can happen in both high and low levels of biomarkers, the receiver-operating characteristic (roc) curve is unsuitable for identifying these levels separately; rather, a statistical method is preferab...

background :score, ost and orai risk assessment tools could reduce the cost burden of bmd tests by selecting the high risk patients to osteoporosis. in this study we compared the ability of these risk assessment measures to assess probability of the osteoporosis among post-menopausal women.   methods : 211 post-menopausal women aged 45-88 years enrolled into the study. all of the patients under...

In this study granulocyte-macrophage colony stimulating factor (CSF) was prepared from rabbit and guinea pig lung tissues. The biological activity of these CSFs was measured on semisolid agar culture and compared with those of mouse and rat. Weight of animals, incubation time and cross-reactivity of CSFs with different bone marrow sources were also investigated. The results showed that both...
