In the Mexico northern have been reported loses estimatesof more than 20% in production by the combination of insects and phyto-pathogen organisms. It also has been observed that some trees can … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 4 · 31 Dec 2011 · 8,179 accessesView PDFCite
Research ArticleOpen accessIn the abstractPreparation-Properties Relation of Mn-Cu Hopcalite CatalystArdita Mele, Ilo Mele, Altin MeleProblem statement: The Mn-Cu hopcalite catalyst was used for the conversion of CO to CO2 at low temperatures. It was the catalyst of choice in the gas masks for respiratory protection in mines, aircrafts, military, spatial laboratories. Approach: The efficiency of hopcalite catalyst depends on its surface parameters. Its surface characteristics can be influenced from the chosen way of the … …American Journal of Applied Sciences, Vol. 9, Issue 2 · 26 Dec 2011 · 7,895 accessesView PDFCite
Research ArticleOpen accessIn the abstractProtective Effect of Enicostemma littorale Blume Methanolic Extract on Gentamicin-Induced Nephrotoxicity in RatsNiraj Mukundray Bhatt, Kinjal Chauhan, Sharad Gupta et al.Problem statement: The Amino glycoside antibiotics cause drug induced nephrotoxicity at therapeutic doses and thus limits the use clinically. Oxidative stress is one of the main reasons for the development of nephrotoxicity. Approach: In light of this the aim of the present study was to investigate the role of mitochondrial as well as post-mitochondrial oxidative stress in the development of … …American Journal of Infectious Diseases, Vol. 7, Issue 4 · 30 Nov 2011 · 9,552 accessesView PDFCite
