A series of microcalorimetric experiments were performed to investigate the effect of La 3+ on the formation of the competent state of Escherichia coli HB101 by using a LKB-2277 BioActivity Monitor at 37°C. The thermogenic curves in the absence and in the presence of La 3+ were obtained. Based...
Samples of healthy tissue were taken from each of six prostatectomy specimens (55–72 yr), digested with acids, and analyzed for selenium by atomic fluorescence spectroscopy. The concentrations for five specimens were 1.32±0.09 µg Se/g dry wt (range 1.24–1.42) and 0.213±0.012 µg Se/g wet...
The aim of this work was to determine the effects of dietary intake vitamin E and selenium (Se) on lipid peroxidation as thiobarbituric acid reactive substances (TBARS) and on the antioxidative defense mechanisms in the liver of rats treated with high doses of prednisolone. Two hundred fifty...
To elucidate quantitative changes of Ca, P, and Mg in the arteries with aging, the authors investigated changes of the mass ratios of Mg to Ca and P in the arteries of Japanese and Thai by inductively coupled plasma-atomic emission spectrometry. The arteries of Japanese that were used were the...
Whether rare earth elements can enter into plant cells remains controversial. This article discusses the ultracellular structural localization of lanthanum (La 3+ ) and europium (Eu 3+ ) in the intact plant cells fed by rare earth elements Eu 3+ and La 3+ . Eu-TTA fluorescence analysis of the...
Forty consecutive healthy pregnant women aged 17–38 yr who attended the antenatal clinic of the Department of Obstetrics and Gynecology, Ankara University in their first trimester participated in the study. The pregnant women were followed up longitudinally until the end of their pregnancy....
Physiological effects of lanthanum ions on the activities of the enzymes in the reactive oxygen species (ROS) scavenging system in leaves of wheat ( Triticum aestivum L.) seedlings were studied. Wheat leaves treated in Hogland solution with 0.1 m M LaCl 3 for 48 h showed increased levels of...
The study covered 152 lung cancer patients and 210 controls. The results of the study indicated decreased selenium (Se) concentrations and lowered activity of erythrocyte antioxidant enzymes (glutathione peroxidase, superoxide dismutase, glutathione- S -transferase) in the blood of lung cancer...
