Effects of 20 mg/kg body weight of abana (ABE) on radiation-induced sickness and mortality in mice exposed to 7 Gy to 12 Gy of gamma irradiation were studied. Treatment of mice with abana 1 h before irradiation delayed the onset of mortality and reduced the symptoms of radiation sickness when compared with the non-drug treated irradiated controls (double distilled water, DDW). Abana provided protection against both the gastrointestinal and haemopoietic deaths. However, animals of both the ABE+irradiation and DDW+irradiation groups did not survive up to 30 days post-irradiation beyond 11 Gy irradiation. The LD(50/30) was found to be 8.5 Gy for the DDW+irradiation group and 10.3 Gy for ABE+irradiation group. The administration of abana resulted in an increase in radiation tolerance by 1.8 Gy, and the dose modification factor (DMF) was found to be 1.2. The irradiation of animals resulted in a dose dependent elevation in lipid peroxidation, and a reduction in glutathione (GSH) concentration on day 31 post-irradiation. Treatment of mice with abana before irradiation caused a significant depletion in lipid peroxidation followed by a significant elevation in GSH concentration in the liver of mice at day 31 post-irradiation. Abana scavenged (*)OH, DPPH, ABTS(*+) and NO(*) in a concentration dependent manner in vitro. Our results indicate that the radioprotective activity of abana may be due to free radical scavenging and increased GSH level in irradiated mice.
Bismuth (Bi) based solar cells have recently attracted significant attention in line with lead-free perovskite solar cells development. In this study, 2-aminothiazolium iodide (ATI) is used to prepare highly crystalline...
Well-defined 1D molybdenum oxide nanostructures were synthesized using the hydrothermal method with sodium dodecyl sulfate as a capping agent with water as a solvent for the supercapacitor application at very low electrolyte concentration. The structural, morphological and optical properties of the as-prepared nanoparticles were characterized using X-ray diffraction, Field Emission Scanning Electron Microscope, and UV-visible spectroscopy. X-ray diffraction and FESEM studies revealed the formation of '1D Molybdenum Oxide nanorods with an average crystallite size of 31 nm. UV-visible spectroscopic analysis showed that the optical bandgap of molybdenum oxide nanorods to be 3.01 eV. The electrochemical performance of as synthesized nanorods was performed by using cyclic voltammetry, galavanostatic charge-discharge, and electrochemical impedance spectroscopy. The maximum specific capacitance obtained was 411 F g −1 in 0.1M NaOH electrolyte solution with excellent rate capability even at higher scan rates. Cyclic retention of 82.4% was observed even after 1000 cycles making it suitable electrode material for high-performance supercapacitor applications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
