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 µg l-1 and with
a mean value of 83.219±29.1 µg 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 0.080±0.125 µg 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. Key words: Arsenic,

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.. Key words: Ambient air,
chlorophyll, air pollution, Mangifera indica , Tamil nadu |

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. Key words: Avifauna, Diversity, Bird species |

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 (290±1 and 680±5 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 µg 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 µg l-1. Key words:Short-term toxicity, Cypermethrin,

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. Key words: Eudrilus eugienea, Eisenea foetida, Balanced diet, Enzyme, Microbes |

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. Key words: Epitopes, ANN, SVM |
