Assessment of the Risk of Breast Cancer Development Applying NCI Tool among Iraqi Women.

Objective: As part of the bioinformatics studies, we utilized National Cancer Institute (NCI)'s Breast Cancer Risk Assessment Tool to estimate the five-year period and lifetime risk of breast cancer development among Iraqi risky women.

Methods: Totally, 110 risky women aged 21-67 (mean=36±7.4) years were interviewed by a series of questions regarding the risk of breast cancer development.

New spectrophotometric assay for assessments of catalase activity in biological samples.

A novel, simple, and accurate colorimetric assay was established for assessments of catalase activity in biological fluids and tissues. HO dissociation rates are directly proportional to catalase activity, and the principle of the present assay is based on reactions of ammonium metavanadate with HO under acidic conditions. The resulting reduction of vanadium (V) to vanadium (III) produces a red-orange peroxovanadium complex with absorbance maxima at 452 nm.
