The conventional crop production practices including intensive tillage and open field residue burning in world’ largest rice-wheat system (RWS) are adversely affecting productivity besides deteriorating natural resources ecosystems’ sustainability. In order to improve productivity, potassium (K) use efficiency apparent K balance, adoption of conservation a RWS with management is considered high...
Background: In recent publications, several mechanisms have been implicated in gentamicin (GM) nephrotoxicity. Reactive oxygen species have been proposed as one of the causative factors of the drug renal side effects. This study was designed to evaluate the protective effects of the antioxidant vitamins against GM-mediated nephropathy in insitu isolated rat kidneys. Methods: Male Sprague-Dawley...
Gentamicin (GM) is an antibiotic widely used against gram-negative infections. However, its clinical application is limited due to its nephrotoxicity. Oxidative stress plays an important role in the nephrotoxicity of gentamicin. Previous studies showed that Rosa canina L. (RC) fruits possess antioxidant, antimutagenic and anticarcinogenic effect. The aim of this study was to investigate the pro...
the methanol extracts of leaves of bauhinia acuminata (mesf) and their different fractions obtained from modified kupchan partitioning method i.e. methanol, pet ether, carbon tetrachloride, chloroform, and aqueous soluble fractions were subjected to biological screening such as total phenolic content and antioxidant activity screening.the amount of total phenolic content differed in different e...
This study develops a methodology of inference for a widely used Cliff-Ord type spatial model containing spatial lags in the dependent variable, exogenous variables, and the disturbance terms, while allowing for unknown heteroskedasticity in the innovations. We first generalize the GMM estimator suggested in Kelejian and Prucha (1998,1999) for the spatial autoregressive parameter in the disturb...
