β-Pinene, an oxygenated monoterpene, is abundantly found in the environment and widely occurring in plants as a constituent of essential oils. We investigated the phytotoxicity of β-pinene against two grassy (Phalaris minor, Echinochloa crus-galli) and one broad-leaved (Cassia occidentalis) weeds in terms of germination and root and shoot growth. β-Pinene(More)
While substantial research has examined the control of information systems (IS) projects, most studies in this area have only examined how one controller manages a single group of controllees. However, many IS projects, especially enterprise systems projects (often initiated by an organization's corporate headquarters, and involving business unit users and(More)
The focus of the present study was to explore lead (Pb)-induced metabolic alterations vis-à-vis ultrastructural changes in wheat roots to establish Pb toxicity syndrome at a structural level. Pb (50–500 μM) enhanced malondialdehyde (an indicator of lipid peroxidation) and hydrogen peroxide content, and electrolyte leakage, thereby suggesting reactive oxygen(More)
OBJECTIVE To assess and evaluate the frequency, severity and classification of drug-related problems (DRP) resulting in hospitalization in an internal medicine department of a large tertiary care hospital and to identify any patient, prescriber, drug, and system factors associated with these events. MATERIALS AND METHODS A prospective and descriptive(More)
We examined the effect of Pb2+ (8 and 40 mg l−1) on reactive oxygen species generation and alterations in antioxidant enzymes in hydroponically grown wheat at 24, 72, and 120 h after exposure. Pb2+ toxicity was more pronounced on root growth, and it correlated with the greater Pb accumulation in roots. Pb exposure (40 mg l−1) enhanced superoxide anion,(More)
Nitric Oxide (NO) is a bioactive signaling molecule that mediates a variety of biotic and abiotic stresses. The present study investigated the role of NO (as SNP [sodium nitroprusside]) in ameliorating lead (Pb)-toxicity in Triticum aestivum (wheat) roots. Pb (50 and 250 μM) alone and in combination with SNP (100 μM) was given to hydroponically grown wheat(More)
The present study investigated the effect of Arsenic (As; 5, 10, 50 μM) on protein and sugar metabolism vis-à-vis oxidative damage during early germination process and radicle emergence (at 12, 24 and 48 h stage) in Phaseolus aureus. As-exposure (50 μM) significantly enhanced protein content (by 40–60%), whereas carbohydrate content declined (by 31–44%)(More)
