  This present study deals with the growth, photosynthesis, oxidative stress and phytoremediation character of Azolla pinnata L. exposed to different levels (0.05, 0.1, 0.5, 1.0, 1.5 and 2.0 mg·L−1) of cadmium (Cd). Significant accumulation of Cd in Azolla fronds was noticed after 24 and 96 h of exposure and the accumulation rate was dose and time dependent. Growth of A. pinnata increased significantly after both exposure times with and without metal. At lower Cd doses (0.05 and 0.1 mg·L−1), growth and photosynthesis of A. pinnata showed a marginal increase over the respective control, however, at higher Cd doses (0.5, 1.0, 1.5 and 2.0 mg·L−1), a decreasing trend was noticed. At lower doses, Azolla fronds could counterbalance the negative effect of enhanced levels of superoxide radicals (SOR) and hydrogen peroxide (H2O2) through the greater activity of antioxidative enzymes. The decaresing trends in catalase and peroxidase activity at higher Cd doses suggest that Azolla fronds were not able to mitigate the negative effects of H2O2, hence an increase in malondialdehyde content was noticed. The study concludes that up to 0.1 ,mg·L−1 Cd, A. pinnata can flourish and be used as biofertiliser and for phytoremedial purposes in Cd-contaminated fields; beyond this concentration poor growth may restrict its application.

  The present study was planned with main objective of identifying buying practices of homemakers and their awareness in food practices in Varanasi (urban area). For this objective, questionnaire was prepared and distributed among selected people depends on their age group, sex and educational background. Statistical test were carried out on the basis of frequency of male and female respondents obtained in total respondents (n = 300). Chi square test were carried out and the calculated value were compared with value of t test (0.05) and on this basis, conclusion were drawn. Correlation between different variables was determined for their impact. Study revealed that educated people of both sexes follow slightly good buying practices while homemakers are not following food practices and also they differ significantly in following the practices in term of use of quality water which affects the family health. Study also revealed that age and awareness are not interlinked while education is interlinked with good practices.

  The present study was carried out (1) to provide nutrition education to the overweight and obese females and (2) to evaluate impact of nutrition education on their food habit and practices of physical exercise. The data were collected with the help of "Questionnaire cum Interview Technique." The questionnaire having all relevant information was pretested and pre designed the data were collected at two phases: one at initial phase of the study before implementation of nutrition education and secondly at post phase of the nutrition education. The base line study was conducted on 300 overweight and obese females purposely selected from four areas of the city. Equal number of subjects (one hundred each) were considered from high, middle and low income groups. Due to various constraints the nutrition education was imparted to 150 subject only. The inferences were drawn with the help of suitable statistical tools. Majority of the females were vegetarian (95.33%) at the initial phase of the study, but there was no change in this habit after imparting the nutrition education (p>0.05NS). So for as consumptions of food items and practices of physical exercise were concerned, there were significant changes (p<0.05). Practicing of good food habits were developed and consumption of sweet dishes, fatty fried items and cold drinks were discouraged.
