A WATER RETENTION SYNDROME, has been described by Sladen 1 et al. in 19 per cent of patients, following prolonged mechanical ventilation. They suggested that changes in left atrial pressure, secondary to intermittent positive pressure ventilation (I.P.P.V.) caused an increase in plasma anti-diuretic hormone with resultant water retention. In studies of plasma anti-dluretic activity of anaesthet...

Pathologic calcification leads to structural deterioration of implant materials via stiffening, stress cracking, and other structural disintegration mechanisms, and the effect can be critical for implants intended for long-term or permanent implantation. This study demonstrates the potential of using specific metal ions (MI)s for inhibiting pathological calcification in polyurethane (PU) implan...

cosmos caudatus is widely used as a traditional medicine in southeast asia. c. caudatus has been reported as a rich source of bioactive  compounds such as ascorbic acid, quercetin, and chlorogenic acid. studies have shown that c. caudatus exhibits high antioxidant capacity and various medicinal properties, including anti-diabetic activity, anti-hypertensive properties, anti-infl ammatory respon...

In this work, the microstructure, mechanical, and anti-wear properties of alloyed-extruded-aged Mg-8.3Gd-4.5Y-1.4Zn-0.3Zr (wt%) alloys were investigated by X-ray diffraction (XRD), scanning electron microscope (SEM), nanoindentation, wear tests. Results showed that alloying—extrusion processing induced a significant grain refinement magnesium resulting in formation bulk Mg24(GdYZn)5 at boundari...

BACKGROUND Heterotopic ossification (HO) is defined as the formation of true bone tissue in non-osseous tissues. HO may occur under several conditions such as soft tissue injury, central nervous system injury and many other diseases like arthopathies, and vasculopathies. The underlying mechanisms of HO are not well elucidated. Anti-NMDA receptor encephalitis is a newly recognized autoimmune med...
