Abstract: This study was conducted to evaluate blood arsenic concentration as a biological marker of drinking water arsenic exposure. Study subjects were ground water sources of arsenic in the different blocks of Baliia at Uttar Pradesh in the upper and middle Ganga plain, India. Analysis of fifty drinking water samples revealed that arsenic level of 55% ground water sources had more than 50 g l-1 and with a mean value of 83.21929.1 g l-1 . The observation of depth and age of borewells showed positive correlation with arsenic concentration found in different ground water sources, however these observations also indicate that older source of ground water had greater chance of arsenic contamination (r = 0.724, t = 4.452 and p < 0.05). The individuals living in high arsenic contaminated zone were regularly exposed to contaminated water. The blood arsenic content in these regions has been detected significantly higher as compared to control (0.334 0.325 and 0.0800.125 g dl-1 respectively). The blood arsenic content correlated significantly with ground water arsenic level (r = 0.850, t = 6.846, p<0.05) and exposure time (r = 0.711, t = 4.290, p<0.05) for population residing in Ballia districts. This study can be considered as an alarm for future as the ground water resources in these zones.

Abstract: The present study was undertaken to predict the impact of air pollution on the chlorophyll content ofcommonly growing trees in Virudhunagar area in Tamilnadu, India.For this, leaf samples of selected plant species in different locations ofstudy area were collected and analyzed for chlorophyll a, chlorophyll b and total chlorophyll. The three different locations identified were Madera coats colony (site-1), Pavali (site-2), Perali (site-3). To have a comparative account, the results were compared with site-1, which may be considered as control site because it was comparatively free from any sort of pollution. Chlorophyll contents of different localities which exposed air pollutions of vehicle traffic and industries have compared throughout six month between december, 2009 and june, 2010.These studies clearly indicate thatthe air pollution altersthe concentration ofphotosynthetic pigments in the trees exposed to air pollution. The selected trees like Delonix regia, Moringa olifera, Ficus religiosa, Ficus benghalensis, Millingtonia hortensis showing increased chlorophyll content. Selected tree species like Pongamia glabra, Eugenia jambolana, Pithecelobium dulce have showna decreasing trend of chlorophyll content. As Virudhunagar is not coming under the air quality monitoring of CPCB and its nation wide programme known as the National Air Quality Monitoring Programme due to shortcomings in the air monitoring regime. By measuring and monitoring chlorophyll content of evergreen plants through out the year we will monitor the air pollution changes in the town..

Abstract: The effects of various zinc concentrations (available 0.3 (control), 2.9, 5.6, 6.8 and 9.5 ppm) in soil were studied on growth (length, and dry matter yield) and biochemicalconstituents (protein, pigments and sugar contents and activity of catalase) in wheat (Triticum aestivum Linn.). Plants grown at high Zn levels (available 5.6, 6.8 and 9.5 ppm) in soil showed visible symptoms of toxicity such as decreased plant growth, chlorosis and tip burning of young leaves and reduced size of leaf lamina. Severity of these symptoms was less at lower concentration of Zn (5.6 and 6.5 ppm). The shoot length and dry matter yield of wheat were decreased maximum at 9.5 ppm available Zn in soil. Pigment, sugar and protein contents were also stimulated in wheat up to 2.9 ppm available Zn in soli. Study concluded that, high available Zn levels above 2.9 ppm in soil reduced growth and biochemical constituents in wheat and exhibited visible symptoms of toxicity, therefore not found suitable for wheat cultivation

Key words: Zinc, biochemical constituents, Triticum aestivum, zinc toxicity in plants

Abstract: Recently there has an elevated interest in biodiversity and its conservation. India abodes about 1710 bird species while the estimated bird species on the earth is around 8600. Various studies have been done on avifauna of university campuses and institutes as well. This study deals with the birds studied in Lucknow University campus, Lucknow. Lucknow is situated in the heart of the great gangetic plain. The observations reveal that the University supports about 47 bird species belonging to 22 families. This is an initial and simplified effort to create awareness and motivate the common mass regarding biodiversity surrounding them.

Abstract:Relative short-term (96 hr) toxicity of cypermethrin to males and females ofa freshwater fish, Poecilia reticulata have been evaluated for selected levels of hardness and pH of the water to estimate the LC50 (median lethal concentration) for different time intervals and presumable safe and dischargeable concentrations. Result indicates thatmales were found more sensitive as compared to females for cypermethrin at both water hardness (2901 and 6805 mg l-1) and pH (5.0, 7.4 and 9.5). Presumable safe concentrations for males and females of Poecilia ranged in between 13.98 to 77.39 g l-1 for selected levels of hardness and pH. Whereas, range of safe dischargeable concentrations of cypermethrin to males and females of Poecilia were recorded as 1.06 to 1.14 g l-1.

Abstract: Vermitechnology is a low cost technology. It provides scope and opportunities in the field of Biotechnology. The sudden decline in biomass may mainly due to the over use of chemicals, and also due to lack of interest among biotechnologists to culture more and more worms to charge, once again, the mother earth with worms. Steps had been taken to enhance the production of biomass of earthworms by providing organic wastes rich in major organic constituents such as Cereals (Carbohydrates), Pulses (Proteins) and Skin of chick (Lipids). Earthworms Eudrilus eugienea and Eisenea foetida were fed with organic constituents individually, and in combination (a balanced diet). The biomass of the earthworms was steadily increasing in the individual treatment and a significant difference was found in both of the genus of the earthworms when fed with balanced diet (combination of all the three). The bacteria identified were Bacillus sp, Lacto Bacillus sp and Flavobacterium sp. Enzymes screened in the gut were Amylase, Endoglucanase, Cellulase, Sucrase and Protease in both except the enzyme Amylase in Eisenia sp. From the present investigation it was found that the balanced diet is the ideal medium in which the biomass of earthworms are high, their enzymatic activity was also high with variety of microbes which will enhance the efficiency of the soil.

Abstract: Dengue virus (DENV) belongs to the family Flaviviridae, genus Flavivirus. Dengue fever (DF) is caused by any of four closely related viruses, or serotypes: dengue 1-4 (DENV 1-4). Infection with one serotype does not protect against the others, and sequential infections put people at greater risk for dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS).Dengue virus is single stranded RNA virus and its genome composed of approximate 11000 bp that encodes three structural proteins and seven non-structural proteins. At present the efficient vaccine is not available in the market against Dengue virus, therefore, there is need to develop an effective vaccine which provide total protection against Dengue virus. We have predicted a potential epitope based vaccine by using CTLPred server which is based on machine learning methods such as artificial neural network (ANN) and support vector machine (SVM). The prediction of the potential and specific epitopes candidates has been done by using ANN, SVM, ANN+SVM combined and ANN+SVM consensus approaches at maximum threshold value. The binding affinity of predicted epitopes has been examined through quantitative matrices (QM) method available on this server.
