Opis:: As far as the detection of metal genotoxicity in fish is concerned, micronucleus (MN) test is considered an extremely suitable measure. In this study, frequencies of micronucleated erythrocytes were scored in peripheral blood of catfish, Heteropneustes fossilis (bloch) after acute in-vivo exposure of zinc at different concentrations (5, 10 and 30 ppm) in the laboratory condition. These three concentrations of zinc were tested at different durations such as 24h, 48h, 72h and 96h respectively. Highly significant (P < 0.001) increased values were obtained for MN frequencies in the peripheral erythrocytes of exposed fishes compared to control groups of fishes. These results confirm that dose- and time-dependent micronucleation in the peripheral erythrocytes of fish after short-term exposure to zinc could provide valuable information regarding zinc containing effluent quality and also help in genetic biomonitoring with this test model. In this context safe concentration of zinc vis-a-vis genotoxicity range could be evaluated for future studies.

Opis:: Management and protection of the ground water is most important, since ground water is considered as the most precious resource in the earth. Once this vital resource is contaminated it will cause several ecological disturbances. In recent years the large-scale occurrence of ground water contamination by some inorganic pollutants like arsenic and fluoride and the associated human sufferings is a threat of this millennium. The severity, magnitude and spread of such problem over the world have reached at an alarming stage (1,2). The source of contamination of ground water is primarily geogenic in origin, with some anthropogenic activities accelerating the problem. The actual mechanism of leaching of the contaminants from the parent minerals to the aquifers is not understood. Still it is clear that indiscriminate use of ground water definitely aggravate the problem. It is estimated that at least sixty four million people in the world are suffering from fluoride related health problem (3) and more than four million people in India, in the state of West Bengal alone (4) are developed the symptom of arsenic toxicity. Both arsenic and fluoride are widely distributed throughout the earth's crust and are introduced into ground water through the dissolution of minerals and ores as well as a result of erosion from local rocks. Industrial effluents also contribute arsenic and fluoride to water in some areas. Arsenic and fluoride are also used commercially, e.g., in alloying agents and wood preservatives. Combustion of fossil fuels is a source of the contaminations in the environment through disperses atmospheric deposition. Arsenic and fluoride from water, sediment, soil and rocks can concentrate in living organisms. Among the different sources of contaminations the pollution of ground water through geological sources are very crucial. The complex pathway and mobilization pattern make the situation very critical. Fluoride and Arsenic poisoning can be prevented or at least minimized by use of alternative water sources and treated water after removal of fluoride and arsenic. Surface water, rainwater and fluoride/arsenic free ground water can be considered as alternative water sources. Among the conventional removal techniques precipitation, adsorption, ion exchange, electrolysis and reverse osmosis can be used. In our laboratory we tested some low cost waste material (viz. fly ash from thermal power plant) and natural material (laterite, the widely available clay in India) for the removal of arsenic and fluoride from contaminated drinking water.
Ostatnie sprawozdania pokazują, że około 26 krajów jest dotkniętych problemem zanieczyszczenia wód gruntowych arsenem, wśród których cztery kraje południowo azjatyckie: Bangladesz, Indie (Zachodni Bengal), Chiny i Tajwan są najbardziej zagrożone. Obecnie w 29 krajach na świecie występuje problem zanieczyszczenia wód gruntowych fluorem pochodzącym tylko ze źródeł geośrodowiskowych. Wpływ na zdrowie przypadku obu tych zanieczyszczeń jest bardzo poważny, a skutki są nieodwracalne i praktycznie nie istnieje żadna kuracji mogąca wyleczyć zakażone osoby. W Indiach bardzo duża populacja cierpi z powodu zatrucia arsenem i fluorem. Ostatnie badania przeprowadzone przez UNICEF wskazują, że co najmniej 213 okręgów w 18 stanach (w tym cztery okręgi Zachodniego Bengalu), jest dotknięte tym problemem. Skala problemu zanieczyszczenia arsenem w Zachodnim Bengalu jest bardzo poważna w dziewięciu okręgach z pośród osiemnastu. Średnia wysokiego stężenia arsenu jest 4,5 razy przekracza wartość tolerowaną przez ludzkie ciało (0,05 mg/L, norma w Indiach). W niektórych miejscach wartość ta przekroczona jest nawet siedmiokrotnie. Najwyższe oznaczone stężenie fluoru w wodzie gruntowej w Zachodnim Bengalu wynosiło 19 mg/L (maksymalna dopuszczalna wartość wg WHO to 0,5 mg/). Największe stężenie fluoru w wodzie gruntowej w Indiach oznaczono w miejscowości Haryana i wynosiło ponad 84 mg/L. Nasze badania we wsiach Nashipur, Bhabanandapur, Nowapara, Chakatla, Junidpur w dzielnicy Rampurhat, okręgu Birbhum, Zachodni Bengal pokazują największe stężenie fluoru wynoszące 16,0 mg/L (prawie 16 razy większe niż granicę dopuszczalną przez WHO). Na terenie badań prawie 90% dzieci w grupie wiekowej poniżej 15 lat posiada rozwinięte symptom fluorozy dentystycznej. W typowych badaniach około 21 000 próbek włosów, paznokci, naskórka i moczu (tylko metabolity arsenu zostały zmierzone) mieszkańców terenów skażonych arsenem zostało zanalizowanych na zawartość arsenu. Około 10÷15% z tych próbek pochodzi od ludzi mających uszkodzenia skóry spowodowane przez arsen. 56%, 80% i 87% z analizowanych próbek zawiera arsen we włosach, paznokciach i moczu w ilościach przekraczających poziom normalnym / toksyczny (włosy).

Opis:: Forest cover in hills is essential to maintain environmental, economic and ecological balances. North Bengal accounts for 3,086 sq km (26 %) of the 11,876 sq km area of classified forests in the state, and for nearly 5,000 sq km (40 %) of all land under tree cover. Upper Chatakpur is one of the emerging ecotourism spots of north Bengal, located at an altitude of 7887 feet in Darjeeling district. It is a 180 years old ethnic village with 19 houses and a population of about 89, and at an altitude of 7887 ft. It is about 8 km. from Sonada (26° 57' N, 88° 16' E), 22 km. from Darjeeling (26° 2' N, 88° 15' E) and 72 km. from Siliguri (26° 42' N, 88° 25' E). Upper Chatakpur Village situated within Senchal Wildlife Sanctuary, Darjeeling. The sanctuary with an area of 38.88 sq. km has an elevation of 1500-2600 m. The survey work was done in December, 2014 by visiting upper Chatakpur village and the primary data were gathered through field survey and direct contact with common people and authorized centers of the region. Surveys on the topography, demography, agriculture, livestock, water management, education, culture, health, waste management, transport, biodiversity, human animal conflict were done in this area. Medicinal plant diversity was studied in the village area and information was gathered from the local forest department centre. Information regarding the transport system was collected from the local transport office and syndicate. Census report was collected from the Sonada Panchayat Office. Health and education information was collected from the local primary school and the local sub health centre. Information on sustainable agricultural practices and waste management policies is collected through surveys in the village houses and agricultural fields. Biodiversity of Senchal Wildlife Sanctuary was documented by visiting the forest areas. Pictorial documentation was done in every phase of study. In spite of getting so much attention in the recent time, the village is not adequately developed. There is an urgent need for implementing sustainable management systems in the areas for the betterment of the socio-environmental structures. Some of the possible management strategies have been suggested for maintaining the social, environmental, economic and ecological balance of the region.

Opis:: Background: This study was based on gender differences in male and female trained tennis players. Aim of the study: The aim of this study was to determine the extent that physical training could minimize the gender differences in lung capacities in trained tennis players aged 14–17 years. Material and methods: The participants were ten male and seven female lawn tennis players, with a mean ± standard deviation (SD) age of 15.5 ± 1.27 and 14.43 ± 1.13 years, respectively. Physical characteristics and lung volumes were measured on the same day for each participant. Data were presented as mean ± SD, and Student’s t-test to compare the measured variables was performed. Results: Differences between genders were insignificant in terms of age (years), weight (kg), body fat (%), lean body mass (kg) and chest circumference (cm). However, height (cm), and W/H ratio were significantly (p < 0.05) higher in male tennis players in comparison to female players. Insignificant differences were found for TV (L), SVC (L), FVC (L), FEV1 (L), FEV1/FVC (%), FEF25-75% (L/s), PEF (L/s) and MVV (L/min). The only significant difference (p < 0.05) in lung function measures between male and female trained tennis players was for PIF (L/s). Conclusions: Male tennis players were taller than female tennis players of same age range, which might be advantageous for males while playing. Insignificant differences between male and female players in the various lung variables measured indicated that the influence of height and gender differences could be minimized by proper training during puberty. A significantly higher PIF in male players indicated stronger and more powerful inspiratory muscle activity compared with female tennis players.

Opis:: Numerous soft-sediment deformation structures occur within the Proterozoic Bhander Limestone of an intracratonic sag basin in a 750 m long section along the Thomas River, near Maihar, central India. Part of these deformation structures have most probably a non-seismic origin, but other structures are interpreted as resulting from earthquake-induced shocks. These seismic structures are concentrated in a 60 cm thick interval, which is interpreted as three stacked seismites. These three seismites are traceable over the entire length of the section. They divide the sedimentary succession in a lower part (including the seismites) deposited in a hypersaline lagoon, and an upper open-marine (shelf) part. Most of the soft-sediment deformations outside the seismite interval occur in a lagoonal intraclastic and muddy facies association. The SSDS within the seismite interval show a lateral continuity. They record simultaneous fluidisation and liquefaction. The bases of each of the three composing seismite bands are defined by small-scale shear folds, probably recording an earthquake and aftershocks. The presence of the three seismite bands at the boundary between the lagoonal and the overlying open-marine oolitic facies association suggests that the seismic event also triggered basin subsidence.

Opis:: During the past two decades, Arsenic (As) contamination via groundwater has become a serious issue worldwide and is now a major concern in the Indo-Bangladesh Gangetic delta. Arsenic enters human body through contaminated groundwater consumed as drinking water. Food safety in this region is also facing severe consequences as bio-accumulation of Arsenic is occurring in food crops irrigated with As-contaminated water. Chronic exposure to Arsenic can cause not only cancerous and non-cancer health effects. Reports suggest that about 20 % population in West Bengal is highly affected. Various techniques are being introduced to provide arsenic-free drinking water at an affordable cost. But a rigorous change in habit and mind set for procuring safe drinking water in those surviving in As-contaminated zones is the most essential step towards curbing the fatal consequences of As exposure. Harvesting rain water and utilization of proper purification techniques can be considered a possible alternative of safe drinking water.

Opis:: A group of polycyclic and aliphatic azido-esters (as energetic plasticizers) have been synthesized by simple synthetic routes and their molecular structures were confirmed by spectroscopic techniques. In addition, their thermal and rheological properties have been determined utilizing DSC, TGA, viscosity, and contact angle. Computational studies of these plasticizers have been performed by means of DFT (B3LYP/6-31G*) to estimate possible stable structures, energies, heat of formation, bond dissociation energies, IR and NMR spectra etc. Their compatibility with glycidyl azide polymer (GAP) binder was studied to explore their applicability in propellants. All of these molecules are novel and have been synthesized with the possibility of scale up.

Opis:: Purpose: To investigate the involvement of oxidative stress in Cadmium (Cd) induced alteration in the functional status of the liver. And to assess the efficacy of folic acid and vitamin B12 in preventing Cd-induced damage in the same. Materials and methods: The experiment was carried out for four weeks. For the experiment, 25 healthy male adult Wistar albino rats were randomly selected and were divided into five equal groups and treated as control, treated with Cd, supplemented with vitamin B12 and folic acid and in the combination of these two. After 28 days the liver function enzymes and oxidative stress parameters were measured. Results: Cd is the silent killer of the hepatic system through the induction of oxidative stress in male rats. From this investigation, it is evident that the folic acid+vitamin B12 possess significant hepatoprotective and antioxidant activity against Cd-induced hepatotoxicity in the rat model. In addition, results revealed that the folic acid alone and or in combination with vitamin B12 blunted the hepatotoxic effect significantly. Conclusions: Based on results obtained, it can be concluded that folic acid and vitamin B12 offer a protective effect in Cd-induced oxidative stress associated with hepatocellular injury. Folic acid and vitamin B12 can be considered as a potent natural antioxidant which has the capacity to provide protection against Cd-induced oxidative stress in the liver in rats. However, to elucidate the exact mechanism of this modulatory effect and to examine its potential therapeutic effects further studies are essential.
