To determine whether extremely low frequency electromagnetic fields can alter average free cytosolic calcium ion concentrations [Ca2+]i and transient increases in [Ca2+]i in populations of ROS 17/2.8 cells.Cells loaded with the calcium-selective lumi

In earlier studies, McLeod and coworkers reported the detection of spontaneous calcium spiking in ROS 17/2.8 cells which they suggested was derived from individual cells progressing through mitosis or the cell cycle. They also indicated that the degr

Recent studies from this laboratory established that dexamethasone (DEX) potentiates Ca2+ current via voltage-gated Ca2+ channels (VGCC), and as a consequence potentiates agonist-induced cytosolic Ca2+ transients in rat adrenal chromaffin cells. The

The authors describe a system for the quantitation of fluorescence light output by individual cells using the signal obtained from a silicon intensifier target video camera. The video image is digitized to 4 bits (16 levels), and a 512 X 512 matrix i

A large quantity of published work indicates that calcium ions may be involved in the regulation of mitotic events and recent reports suggest that the onset of chromosome movement is dependent upon a transient increase in free cytosolic calcium ions.

A time lapse cinemicrographic study shows that, at low concentrations, nicotine can speed up cytokinesis and, at high concentrations, prolong the duration of metaphase in HeLa cells. Based upon the known effects of the alkaloid in other systems, it a

It is clear that QVIM systems, when combined with appropriate fluorescent probes can be utilized to perform quantitative cytochemical studies on living and fixed cells. They also have the potential to facilitate studies of substances which like Ca++

In this paper we describe a system for the quantitation and display of fluorescence at the cellular level. It uses a low light level video camera which is interfaced to a fluorescence microscope and to a microprocessor-controlled video digitizing sys
