Bioaccumulation of heavy metals in fish tissues of a freshwater lake of Bhopal

Abstract: Contamination of heavy metals, namely, lead, cadmium, zinc, nickel, copper, chromium and mercury was evaluated in the samples of water and tissues of Labeo rohita and Ctenopharyngodon idella of Upper Lake of Bhopal collected during summer, rainy and winter seasons of 2005-2006. Different organs of the fishes accumulated varying quantities of different heavy metals. In L. rohita, accumulation of heavy metals was in the sequence liver>kidney>gills>muscles, and in C. idella, it was gills>liver>kidney>muscles. Zn was the highest accumulating metal in fish, whilst Hg was the lowest and was well corroborated with those of water. The values of heavy metals were so far well within the maximum permissible standard value of heavy metals for drinking water and for fish culture as prescribed by various national and international agencies.

Nanotechnology Applications in Food and Food Processing: Innovative Green Approaches, Opportunities and Uncertainties for Global Market

Abstract: Nanoscience and nanotechnology are new frontiers of this century and food nanotechnology is an emerging technology. Their applications to the agriculture and food sector are relatively recent compared with their use in drug delivery and pharmaceuticals. Many scientists and engineers have recognized well the potential of nanotechnology to lead all the food industries in the 21st century. Even though successful applications of nanotechnology to foods are still limited, some basic concepts based on nanoscale have been established well. In food engineering field, two major applications related to nanotechnology, that is, food nanosensing and food nanostructured ingredients are being expected. In the former field, better food quality and safety evaluation can be achieved by using nanotechnology. Advances in technologies, such as DNA microarrays, microelectromechanical systems, and microfluidics, will enable the realization of the potential of nanotechnology for food applications. In the latter, food p...

Social Construction of Emotions

Abstract: The traditional view that emotions are primarily biological, involuntary bodily changes or evolved adaptations has been challenged by social constructivists such as psychologists, anthropologist and philosopher Claire The proponents of the social constructivist approach argue that emotions have meaning and are experienced and expressed in a particular socio-cultural context According to “emotions are not only remnants of our phylogenetic past, nor can they be explained in strictly physiological terms Rather, they are social constructions, and they can be fully understood only on a social level of analysis” Keywords: emotion; emotional development

Nanotechnology-Based Drug Delivery Systems

Abstract: In recent years, there has been a considerable interest in the development of novel drug delivery systems using nanotechnology. Nanoparticles represent a promising drug delivery system of controlled and targeted release. In this context, nanosuspensions will be effective in increasing the solubility and bioavailability of poorly soluble drugs. This review focuses on advantages, method of preparation, physical characteristics, and evaluation of drug nanosuspensions.
