Solid-liquid phase change thermal diode (SL-PCTD) is potential for rectification, however the unsustainable rectification ratio of SL-PCTD hampers its practical application, demanding a reasonably compatible design. Herein, composed calcium chloride hexahydrate (CaCl2·6H2O) and paraffin wax investigated, where supercooling effect CaCl2·6H2O plays significant role in rectification. In forward di...

BACKGROUND Methanthelinium bromide is a quaternary ammonium derivate with anticholinergic activity. Since 1951 it has been used to treat patients with hyperhidrosis. However, all efficacy data has so far been limited to case reports and case series. We here report on the results of the first randomised clinical controlled trial on the efficacy and safety of methanthelinium bromide. PATIENTS A...

Aluminium (Al) toxicity is closely linked to the pathogenesis of Alzheimer's disease (AD). This experimental study investigated the neuroprotective effect of melatonin (Mel; 10 mg/kg bwt) on aluminium chloride (AlCl3 ; 34 mg/kg bwt) induced neurotoxicity and oxidative stress in rats. Adult male albino Wistar rats were injected with AlCl3 for 7 days. The effect on brain structure, lipid peroxida...
