Impact of industrial effluents on some biomarker enzymes in selected tissues of Arius maculates from Uppanar Estuary,...
Kumaresan,T and Karuppasamy, R.

The present study is aimed to investigate enzyme studies in the gill and liver tissue of estuary fish Arius maculates exposed to sublethal concentration of efflunts. In the present study, the activity of Acid phosphatase (ACP), alkaline phosphatase(ALP), Glutamate Oxaloacetate Transaminase (GOT) and Glutamate Pyruvate Transaminase (GPT) were observed in the gill and liver tissue. During the sublethal concentration of effluents, the Acid phosphatase, alkaline phosphatase, Glutamate...

The food woody species of food shortage in few communes of burkina faso
Thiombiano D.N.E., Lamien N., Dibong S.D. and Boussim I.J.

In order to contribute to the utilization and permanent conservation of the species, the present study was conducted in Pobé-Mengao (sahelian region) and Nobéré (soudanian region) in Burkina Faso. The method of study included ethnobotanical surveys based on participatory method (MARP). The results show that the agricultural shortage period is longer in Pobé-Mengao (five months) than Nobéré (four month). A total of eight species were found in Pobé-Mengao and thirteen species in Nobéré were...

Increased frequency of micronuclei and sister chromatid exchange in cement factory workers
V. Ramakrishnan

The population most exposed to cement dust pollution includes workers and managers in cement plants and factories, families of workers and managers living in staff houses of factories, and other neighbourhood habitations. Children studying in the schools situated in proximity to factories are particularly prone to cement dust exposure. In this study, the micronuclei (MN) and sister chormatid exchange (SCE) was applied in peripheral blood lymphocytes cells, in order to assess the genotoxic...

Measurement of centripetal force with high percentage accuracy using force sensor and photo-gate
Hamza Zafar and Syed Karrar Haider

This paper describes the experimental work to measure the centripetal force using a force sensor and a photo-gate, and analysis with data acquisition software. The result of this experiment provides high percentage accuracy in the measurement of centripetal force; importance of sensors to analyze the force and velocity in order to obtain accurate measurements.

Effect of medium in shoot tips and nodal segments of Andrographis paniculataAnkita Kataky and PJ Handique
Ankita Kataky and PJ Handique

Selection of an appropriate culture medium and the use of correct growth regulators were critical for the optimum growth response of the explants. Three different media formulations Murashige and Skoog (MS), Gamborg (B5) and Nitsch were tested to find out the best nutrient composition for successful micropropagation of A. paniculata. In MS medium initial bud break was observed within 5 days of culture with a maximum average of 2.2 shoots after 30 days of culture. In Gamborg’s medium slight...

Bioassay of micropropagated Andrographis paniculata: An overview
Ankita Kataky and PJ Handique

The present investigation is an overview on the biological assay done earlier on micropropagated plants of Andrographis paniculata. The effectiveness of the active compounds present in the plant extracts cause the production of growth inhibition zones that appear as clear areas surrounding the wells. Antimicrobial activity may be due to active components which are present in plant extracts. Regarding the solvent system for antioxidant assay, the method seems to work well with methanol or...

Bioenergetic study of renal β-glucuronidase in indian major carp, Labeo rohita
Arun M. Chilke

β-Glucuronidase is a lysosomal enzyme. It plays an important role in carbohydrate metabolism. The renal β-glucuronidase at optimum pH-5 was observed to produce ∆G, -2.074 kcal/mole at 453 K. Reduction in ∆G was recorded above and below these pH optima. With the increase in temperature, the ∆G was decreased from -2.3 kcal/mole at 358 K to -10.2 kcal/mole at 834 K at constant pH-4.5. However, with the increase in enzyme and substrate concentration ∆G was seen to increase at constant...

Investigation of botanical additives for growth of Xiphophorus helleri (heckel.) and it’s gut autochthonous bacterial...
Baby Joseph S. Sujatha and Shakunthala Madavendra

Effect of Botanical Based Diet Supplementary Probiotic (BBD) and a mixture of fish gut hostile bacterial flora such as Lactobacillus sp. and Bacillus sp. (FG probiotic) on the growth of ornamental fish red orange sword tail fish of Xiphophorus helleri was investigated. The FM at a level of 5g / kg feed had no effect on growth rate rather it reduced the growth compared to control group. On the other hand, in FM probiotic feed fed X. helleri except FCR (P<0.01) the variations in growth...

Their age ranged between eighteen to twenty two years. The...

Anti-inflammatory activity of Lawsonia ulba Linn., in Wistar albino rats
V. Nithya

Anti-inflammatory activity of Lawsonia ulba linn., on carrageenan induced paw edema in wistar male rats Aqueous, ethanolic and methanolic extracts of Lawsonia ulba linn., were investigated for anti-inflammatory activity in carrageenan induced paw edema in wistar male rats, and compared to a positive control drug, Voveran. These extracts were given (ip) in a concentration of 20 and 50 mg/kg b.w. before carrageenan injection. Methanolic extracts of Lawsonia ulba linn., with a concentration of...

Growth of nonlinear optical material: 1-hydroxyurea hydrate crystal and its characterization
Sakthivel, N. and Anbarasan, P.M.

1-Hydroxyurea Hydrate an intriguing new organic material for frequency conversion has been grown by slow evaporation solution growth technique at room temperature. Their structural and physicochemical properties were characterized by X-ray powder diffraction, Dielectric studies, UV-Vis spectra and Hardness studies. The crystal belongs monoclinic symmetry with the space group P21/c, a well-known noncentrosymmetric space group thus satisfying the requirements for second-order NLO activity. The...

Prerak’s training in continuing education programe
A. Senthil Kumar and Dr. T. Rangasamy

Education is a continuous process taking place throughout the life of an individual. It is not confined to pre-specified times and places, but happens whenever a person reflects on the current situation, resolves to address a problem, to share an idea, or to gain an understanding. As the knowledge and skills enable the people to prosper throughout a life time, people will need continually to enhance their abilities, in order to address immediate problem and to participate in a process of...

In vitro evaluation of phenol, flavonoid and antioxidant properties of methanolic extract of Phyllanthus fraternus...
