International Journal of Molecular Sciences , 2012, DOI: 10.3390/ijms13089615
Abstract: Evolution of reactive oxygen species (ROS), generated during the patho-physiological stress of nervous tissue, has been implicated in the etiology of several progressive human neurological disorders including Alzheimer’s disease (AD) and amylotrophic lateral sclerosis (ALS). In this brief communication we used mixed isomers of 5-(and-6)-carboxy-2′,7′-dichlorofluorescein diacetate (carboxy-DCFDA; C 25H 14C l2O 9; MW 529.3), a novel fluorescent indicator, to assess ROS generation within human neuronal-glial (HNG) cells in primary co-culture. We introduced pathological stress using the sulfates of 12 environmentally-, industrially- and agriculturally-relevant divalent and trivalent metals including Al, Cd, Cu, Fe, Hg, Ga, Mg, Mn, Ni, Pb, Sn and Zn. In this experimental test system, of all the metal sulfates analyzed, aluminum sulfate showed by far the greatest ability to induce intracellular ROS. These studies indicate the utility of using isomeric mixtures of carboxy-H 2DCFDA diacetates as novel and highly sensitive, long-lasting, cell-permeant, fluorescein-based tracers for quantifying ROS generation in intact, metabolizing human brain cells, and in analyzing the potential epigenetic contribution of different metal sulfates to ROS-generation and ROS-mediated neurological dysfunction.

Shekhar Bhattacharjee,Swapna Bhattacharjee
Journal of Enam Medical College , 2011, DOI: http://dx.doi.org/10.3329/jemc.v1i2.11468
Abstract: Primary pulmonary hypertension (PPH) is a rare disease which usually presents with shortness of breath. We report a case of a female patient who presented with dyspnoea. We diagnosed her as a case of PPH on the basis of detailed history, careful physical examination and common investigations like electrocardiogram (ECG), chest radiography and Doppler echocardiograhy.
A Bayesian Approach to Compare the Statewise Dengue Death Counts in India '
Atanu Bhattacharjee,Dibyojyoti Bhattacharjee
International Journal of Collaborative Research on Internal Medicine & Public Health , 2011,
Abstract: Background: The Estimation of the true disease burden of dengue is a challenge, considering its varied epidemiology and dynamics of transmission. The true disease burden cannot be understood from ordinary count data on the number of deaths or number of infected cases.Aim & Objectives: To compare the Indian states by the true disease burden due to dengue in the year 2010 by ranking with respect to their performance to deal with dengue death.Methods: To compare the states by count data for observed deaths, the Bayesian approach is used. The source of data is the National Dengue Control Report published by National Vector Borne Disease Control Programme of 2009 and 2010 till the month of August. The statewise comparison of death due to dengue has been performed with all necessary computation done in the statistical software R.Results: Certain states like Delhi, Gujarat and Andhra Pradesh had very high incidence of dengue cases. But the mortality per unit exposure due to dengue is less in Delhi in contrast to other state in the country. Conclusion: This statewise dengue death comparison can be helpful to authorize the state specific dengue control programme, as several issues which are not clear from count data can surface from such analysis.
Effect of Dual Inoculation of Arbuscular Mycorrhiza and Rhizobium on the Chlorophyll, Nitrogen and Phosphorus Contents of Pigeon Pea (Cajanus cajan L.)  [PDF]
Sujata Bhattacharjee, Gouri Dutta Sharma
Advances in Microbiology (AiM) , 2012, DOI: 10.4236/aim.2012.24072
Abstract:

The pot experiments were conducted in the Department of Life Science and Bioinformatics of Assam University, Silchar. The aim of the present study was to investigate the effect of dual inoculation of Arbuscular mycorrhiza (AM) (Glomus fasciculatum) and Rhizobium on the chlorophyll, nitrogen and phosphorus contents of pigeon pea (Cajanus cajan L.). The results revealed an overall increase in chlorophyll, nitrogen and phosphorus contents in the inoculated plants than uninoculated ones. Maximum chlorophyll contents were recorded in the plants dually inoculated with Glomus fasciculatum and Rhizobium. The combined application of Glomus fasciculatum and Rhizobium also remarkably increased the nitrogen and phosphorus contents of pigeon pea. The dual inoculation with microsymbionts revealed synergistic effect. The results suggest that dual inoculation of Glomus fasciculatum and Rhizobium have the potential to enhance the chlorophyll, nitrogen and phosphorus contents of pigeon pea.

Delayed accumulation of lens material behind the foldable intraocular lens
Bhattacharjee Harsha,Bhattacharjee Kasturi,Bhattacharjee Pankaj
Indian Journal of Ophthalmology , 2007,
Abstract: Foldable acrylic intraocular lenses (IOLs) are known to reduce posterior capsule opacification by preventing migration of lens epithelial cells with its square edge design and its property of tackiness. Studies have reported a mean adhesiveness to posterior capsule more than three times higher for certain acrylic foldable IOLs than polymethyl methacrylate IOLs. The authors would like to report two cases where the force of tackiness was compensated, thereby presenting with delayed accumulation of lens material in the capsular bags behind the IOL with temporary loss of vision.
The Language of Reactive Oxygen Species Signaling in Plants

Journal of Botany , 2012, DOI: 10.1155/2012/985298
Abstract: Reactive oxygen species (ROS) are astonishingly versatile molecular species and radicals that are poised at the core of a sophisticated network of signaling pathways of plants and act as core regulator of cell physiology and cellular responses to environment. ROS are continuously generated in plants as an inevitable consequence of redox cascades of aerobic metabolism. In one hand, plants are surfeited with the mechanism to combat reactive oxygen species, in other circumstances, plants appear to purposefully generate (oxidative burst) and exploit ROS or ROS-induced secondary breakdown products for the regulation of almost every aspect of plant biology, from perception of environmental cues to gene expression. The molecular language associated with ROS-mediated signal transduction, leading to modulation in gene expression to be one of the specific early stress response in the acclamatory performance of the plant. They may even act as “second messenger” modulating the activities of specific proteins or expression of genes by changing redox balance of the cell. The network of redox signals orchestrates metabolism for regulating energy production to utilization, interfering with primary signaling agents (hormones) to respond to changing environmental cues at every stage of plant development. The oxidative lipid peroxidation products and the resulting generated products thereof (associated with stress and senescence) also represent “biological signals,” which do not require preceding activation of genes. Unlike ROS-induced expression of genes, these lipid peroxidation products produce nonspecific response to a large variety of environmental stresses. The present review explores the specific and nonspecific signaling language of reactive oxygen species in plant acclamatory defense processes, controlled cell death, and development. Special emphasis is given to ROS and redox-regulated gene expression and the role of redox-sensitive proteins in signal transduction event. It also describes the emerging complexity of apparently contradictory roles that ROS play in cellular physiology to ascertain their position in the life of the plant. 1. Introduction Environmental stresses such as extremes of temperature, salinity, drought, heavy metals, herbicides and pathogens greatly affect plant metabolism and productivity [1]. Because of environmental stress, the yield potential of the crops is hardly realized. It has been estimated that a country like USA is being able to harvest approximately one fourth of the genetic potential of the crop [1, 2]. To survive plant have

Abstract: If I went to work in a factory, the first thing I' do is join a union. Franklin D Roosevelt. Trade Union is a continuous association of wage earners for the purpose of maintaining and improving the conditions of their working lives (Sidney and Beatrics) These associations are formed for collective action of the forwarding of defence of its professional interest(Chamber's Encyclopedia) Joint councils, Quality circles and participatory management are for salary earners to maintain an healthy work culture The function of all the four help the organization as a whole to work effectively and smoothly and maintains a close knitted organizational workforce The study of Union and particularly trade unions are not new, there are innumerable studies outlining the basic facts, features, history, growth, theories and governance issues of the trade union. This paper attempts to highlight the role, objectives, functions, registration, rights and the reasons to join a trade union. It also outlines the role of joint management councils, quality circle and participatory management and understands their importance in the functioning of an organization. This paper is on outcome of reviewing secondary sources of data contributed by eminent scholars.
