There are many functions which are provided by operating system like process management, memory management, file management, input/output management, networking, protection system and command interpreter system. In these functions, the process management is most important function because operating system is a system program that means at the runtime(More)
Two substituted quinazolinyl/imidazolyl-salicylic acids 5, 6 were synthesized by the reaction of 6-iodo-2-methylbenzoxazin-4-one/5-nitroimidazole with 5-aminosalicylic acid (5-ASA). Coupling of compounds 5 and 6 with different amino acid ester hydrochlorides, dipeptide and tripeptide methyl esters yielded novel quinazolino/imidazolopeptide derivatives 5a-f(More)
BACKGROUND Multidrug resistant (MDR) and extensively-drug resistant (XDR) tuberculosis (TB) are a serious threat to the national TB control programs of developing countries, and the situation is further worsened by the human immunodeficiency virus (HIV) pandemic. The literature regarding MDR/XDR-TB is, however, scanty from most parts of India. We carried(More)
INTRODUCTION Helicobacter pylori (H. pylori) infection has been associated with increased levels of inflammatory cytokines and subsequent insulin resistance and epidemiologically linked to type 2 diabetes. OBJECTIVES To study the prevalence rate of H. pylori infection in type 2 diabetes and its relation with HbA1C levels. MATERIALS AND METHODS In this(More)
BACKGROUND Teeth when subjected to bleaching bring about the desiccation of the enamel, making it more susceptible to stain absorption. While subjecting the freshly bleached enamel surface to various surface treatments of Fluoride and Casein Phosphopeptide - Amorphous Calcium phosphate (CPP-ACP) brought about the reduction in stain absorption, which is(More)
Angiotensin II subtype I receptor constitutes a successful target for the treatment of hypertension and cardiovascular diseases. In this study, the pharmacophore search was used to identify structural features that are common in the set of 4H-1,2,4-triazoles. The HypoGen algorithms implemented in the Catalyst software package was employed to create(More)
Wheat accounts for 19% of the total production of major cereal crops in the world. In view of ever increasing population and demand for global food production, there is an imperative need of 40-60% increase in wheat production to meet the requirement of developing world in coming 40 years. However, both biotic and abiotic stresses are major hurdles for(More)
An efficient multiple shoot cluster regeneration and micro-bulb induction protocol was developed for Asiatic hybrid lily (Lilium sp.). Highest multiple shoot cluster formation of 78.4 % was observed on MS medium supplemented with 0.25 mg l−1 BAP and 1.0 mg l−1 GA3. The growth regulators, i.e., abscisic acid, daminozide and chlorocholine chloride,(More)
A combined ligand and structure-based drug design approach provides a synergistic advantage over either methods performed individually. Present work bestows a good assembly of ligand and structure-based pharmacophore generation concept. Ligand-oriented study was accomplished by employing the HypoGen module of Catalyst in which we have translated the(More)
A novel series of 2-amino-4-(coumarin-3-yl)-6-substituted phenyl pyrimidines (5a–h) were synthesized from 3-acetylcoumarin (3). The structures of the synthesized compounds were elucidated by I.R., 1H NMR, 13C NMR, and Mass spectroscopic techniques. The synthesized compounds were screened for in vivo analgesic activities at a dose of 20 mg/kg body weight(More)
