Follow-up of need for dental treatment in 126 patients who have received radiation treatment to the head and neck region.

Objectives: The aim of this study was to evaluate the need for dental treatment, compliance with post-radiation prophylactic care and incidence of long-term complications following radiotherapy to the head and neck.

Methods: The study is a retrospective analysis of dental records of patients referred for oral examination before radiation treatment to the head and neck between 2006 and 2016. Data of dental status and need for dental treatment before radiation therapy were used as baseline information.

Cytoplasmic Ca2+ oscillations in human leukemia T-cells are reduced by 50 Hz magnetic fields.

The effect of 50 Hz magnetic fields on the cytosolic calcium oscillator in Jurkat E6.1 cells was investigated for field strengths within the range from 0 to 0.40 mT root mean square.

The influence of 50-Hz magnetic fields on cytoplasmic Ca2+ oscillations in human leukemia T-cells.

We have studied the effects of 50-Hz 100-microT rms magnetic fields on intracellular Ca2+ concentration in the Jurkat T lymphocyte variant E6.1 using fluorescent probes Indo-1 and Fura-2. We found, however, that the pattern of intracellular Ca2+ fluctuations also depended on the agent used for cell attachment, in our case the polypeptide poly-L-lysine.

Effect of microwave radiation on permeability of liposomes. Evidence against non-thermal leakage.

The effect of 2.45 GHz microwave radiation on the permeability of unilamellar phosphatidylcholine liposomes has been studied. Leakage of 5(6)-carboxyfluorescein from the liposomes was measured using spectrofluorimetry after exposure to either microwaves or thermal heating for 5-20 min intervals.
