1.Compelling epidemiological, experimental and clinical data has established that excess salt intake is associated with a higher cardiovascular morbidity and mortality. Several prospective cohort studies and clinical outcome trials have recognized the reduced risk of cardiovascular disease associated with a lower salt intake. The major benefits appear to accrue from a reductions in blood pressure as a result of salt restriction. As a result, efforts are being made by several countries to reduce the salt intake from the current level of 9-12 g/day to less than 5-6 g/day.

2.Patients with mental illnesses suffer from a multitude of co-morbid conditions resulting in increased morbidity and premature mortality. It is estimated that patients with mental illnesses die about 25 years prematurely. Patient suffering from schizophrenia have a much higher rate of smoking and smoke more cigarettes than the general population. Smoking cessation in this population can help address the disproportionate morbidity and mortality seen in these patients.

3.The present article is aimed to improve the quality of pharmacy education and research in India and various steps to be taken for enhancing the quality in pharma education. Quality in business, engineering and manufacturing has a pragmatic interpretation as the non-inferiority or superiority of something; it is also defined as fitness for purpose. Quality is a perceptual, conditional, and somewhat subjective attribute and may be understood differently by different people. The current era of globalization has witnessed evolution in the professions of the health sector, especially in pharmacy. Whereas previously the pharmacist worldwide was seen as responsible primarily for manufacturing and supplying medicines, today the pharmacist’s role has evolved towards a clinical orientation.

4.A detailed study of the proton affinities of a series of β-substituted acrylamides and their Oprotonated counterparts has been performed by B3LYP (DFT) method using 6-311G(d,p) basis sets with complete geometry optimization both before and after protonation. The gas phase O-protonation is observed to be exothermic and the local stereochemical disposition of the proton is found to be almost the same in each case. The presence of β-substituent is seen to cause very little change of the proton affinities, relative to the unsubstituted acrylamides. Computed proton affinities are sought to be correlated with a number of computed system parameters such as the Mulliken net charge on the carbonyl oxygen of the unprotonated bases, Mulliken net charge on the carbonyl oxygen and Mulliken net charge on the proton of the protonated bases.
