Molecular epidemiological studies of populations at high risk for liver cancer have shown that hepatitis B virus (HBV) and aflatoxin B1 exposures are two major risk factors for this disease. Oltipraz is currently being considered for clinical trial t

Clinical management of ductal carcinoma in situ (DCIS) remains a challenge because significant proportions of patients experience recurrence after conservative surgical treatment. Unfortunately, it is difficult to prospectively identify, using object

The objective of the study was to compare three methods of monitoring the inhibition by dietary theaflavins of N-nitrosomethylbenzylamine (NMBA)-induced rat esophageal intraepithelial neoplasia: the mean tile grade, measured by computer-assisted quan

Our objective was to grade, by computer-assisted quantitative image tile analysis, the intraepithelial neoplasia (also called dysplasia) that develops in esophagi of rats given N-nitrosomethybenzylamine (NMBA) for 5 weeks. To perform image tile analy

Endpoint markers for cancer chemoprevention clinical trials are described that are developed from the morphological properties of the precancerous lesion of intraepithelial neoplasia itself, as measured by computer-assisted quantitative image analysi

This paper proposes a scientific basis and possible strategy for applying surrogate end points in chemopreventive drug development. The potential surrogate end points for cancer incidence described are both phenotypic (at the tissue, cellular, and mo

A new image morphometric method of nuclear grading is described and assessed in the context of the evaluation of histological samples from ductal carcinoma in situ of the breast and cervical intraepithelial neoplasia. The method results in a continuo

The Chemoprevention Branch, NCI, is supporting over 80 clinical trials of chemopreventive agents and has dozens of drugs under development. The structural and functional properties of epithelial precancer (also called preinvasive or IEN), such as inc
Protective action of plant polyphenols on radiation-induced chromatid breaks in cultured human cells
Publikováno v:
Anticancer research. 18(5A)
The present study was performed to determine whether plant polyphenols can protect human cells against radiation-induced DNA damage manifested as chromatid breaks. Since each chromatid contains a single continuous molecule of double stranded DNA, chr
