The purpose of this study was to evaluate the psychological impact of breast cancer screening by use of mammography and/or ultrasound, and to reveal factors related to psychological distress. Three hundred and twenty women were recalled to our hospit

The effects of exposure to a 50 Hz magnetic field (maximum of 41.7 to 43.6 mT) on the membrane protein structures of living HeLa cells were studied using attenuated total reflection infrared spectroscopy. One min of such exposure shifted peak absorba

This study was made to explain the mechanisms for the effects of exposure to a time varying 1.51 T magnetic field on the intracellular Ca(2+) signaling pathway. The exposure inhibited an increase in intracellular Ca(2+) concentration ([Ca(2+)](i)) in

Cell cycle progression of synchronized HeLa cells was studied by measuring labeling of the nuclei with [3H]thymidine. The progression was arrested in a chemically defined medium in which K+ was replaced by Rb+ (Rb-CDM) but was restored upon addition

Human gingival fibroblasts in confluent cultures were continuously exposed to a static 0.2 T magnetic field for 6 or 8 months. Culture flasks were not changed during the exposure, but culture medium was renewed. After dilution and mixing of the cultu

Both attached and suspended HeLa cells swelled in a medium of a hypotonic osmolality of 235 mosmol/kg H2O. When the osmolality was further decreased to 166 mosmol/kg H2O, attached cells instantly swelled and then rapidly lost water and K+, followed b

Exposure of pheochromocytoma (PC 12) cells to a time-varying 1.51 T magnetic field inhibited an increase in the intracellular Ca2+ concentration ([Ca2+]i) induced by addition of caffeine to Ca2+-free medium. This inhibition occurred after a 15-min ex

Effects of a switched, time-varying 1.7 T magnetic field on Rb+(K+) uptake by HeLa S3 cells incubated in an isosmotic high K+ medium were examined. The magnetic flux density was varied intermittently from 0.07–1.7 T at an interval of 3 s. K+ uptake

We tested the effects of exposure to a time-varying magnetic field changing between 0.07 and 1.7 T at an interval of 3 s on transient increase in intracellular Ca2+ stimulated by bradykinin in bovine adrenal chromaffin cells. Addition of bradykinin i

Cerebral blood volume flow and flow velocity have been reported to increase during dynamic exercise, but whether the two increase in parallel and whether both increases occur as functions of exercise intensity remain unsettled. In this study, blood f
