Implications of Low Energy X-ray Emission from Millisecond Pulsars

Low energy X-ray emission (0.1-10 keV) from all six millisecond pulsars (MSPs) for which such emission has been reported support a proposed pulsar magnetic field evolution previously compared only to radiopulse data: old, very strongly spun-up neutron stars become mainly orthogonal rotators (magnetic dipole moment perpendicular to stellar spin) or aligned rotators. The neutron star properties w...

Effect of low dose X-ray on membrane fluidity of thalassemic red blood cells

Background: Chest X-ray is one of the examinations required for an annual health checkup. The interaction of radiation to the medium produces free radicals, which consequently causes biological changes either structural or properties of the cells. Whether the radiation from Chest X-ray upright technique affects the plasma membrane fluidity of thalassemic red blood cells (RBCs) is still unclear....

Comparison of Bone Mineral Density Measured by Dual X-ray, Axial Dual-energy Photon X-ray Absorptiometry and Laser Absorptiometry of Calcaneus

The objective of this study was to validate the use of bone mineral measurements of the calcaneus bone by dual X-ray and laser (DXL) in a cross-sectional study carried out in an osteoporosis clinic. Measurements of bone mineral density (BMD) at proximal femur and spine were obtained by dual-energy photon X-ray absorptiometry (DEXA). Osteoporosis was defined by a DEXA T-score <-2.5 at the femora...
