rubidium/breast neoplasms

The red blood cell (RBC) uptake of rubidium-86 (Rb-86), a sensitive in vitro test of RBC membrane transport, was measured in 22 controls, 8 patients with benign breast lesions, and 30 stage I/II, 13 stage III/IV untreated breast cancers. Total Rb-86 transport was measured. Following ouabain block,

BACKGROUND Rubidium is a putative anticancer agent, but no studies have been performed on the association of rubidium levels in biospecimen with breast cancer risk and the potential as a biomarker of the risk assessment. METHODS Survey data and urine specimens were collected from 240 women with

Lithium, which is used to treat bipolar psychiatric disorders, can stimulate proliferation of a number of cells in tissue culture. Proliferation of MCF-7 human breast cancer cells, which also respond to EGF and estrogens, was stimulated by LiCl (1-5 mM) within the concentration range that is

Breast cancer is the second leading cause of death in women and thus has received a great deal of attention by researchers. Recent studies suggested decreased occurrence of cancer in patients treated with cardiac glycosides (CGs) for heart conditions. Because CGs induce their cellular effects via

Histologically normal and neoplastic human breast tissues obtained from 25 patients at the time of mastectomy were homogenized (200 mg/ml) in distilled water and 5-microliter aliquots dried on Formvar films for trace element analysis by energy-dispersive X-ray fluorescence. The elements measured
