The present paper describes three chelate polymers of transition metals were synthesized by interaction between suberoyl bis (paramethoxyphenylcarbamide) with metal acetate using dimethylformamide as solvent. The newly synthesized chelate polymers were found colored and insoluble in all common organic solvents. The resulting polymers were characterized by elemental analysis, Fourier Transform Infrared Spectrophotometer (FTIR), X-ray diffractrometric and Thermogravimetric Analysis (TGA). The half decomposition temperature and lattice water of polymers were determined by thermogravimetric analysis. On the basis of above studies, the chelate polymers were found to have tetrahedral geometry. Furthermore, solid state conductivity of all chelate polymers has been measured in compressed pellet form over 311 K and found conductivity in range 6.15 × 10-10 – 1.8 × 10-5
cm-1 which indicates the semiconductor nature. The crystalline and amorphous natures of metal chelate polymers were determined by X-RD. SEM studies determine surface morphology of polymers. SEM images of these chelate compounds were shown at higher magnification and data reveal that, particle sizes of chelate compounds were found to be micro level. This technique was noteworthy helpful to identify the difference in morphology of chelating ligand and their chelate polymers.

Vanadium complexes of 3-Hydroxy flavones have been synthesized using 3-Hydroxy flavones and vanadyl acetylacetonate in the stiochiometric ratio 2:1. Their structures have been established on the basis of elemental, spectral analysis (UV, IR, 1H NMR), and mass spectrometry. The synthesized compounds were tested for antimicrobial activity by cup plate diffusion method. The results indicate the enhanced activity of metal complexes over the parent ligands.

Phenolic compounds make up one of the major families of secondary metabolites in plants and they represent a diverse group of compounds. Phenolics can be broadly divided into non-soluble compounds such as condensed tannins, lignins, and cell-wall bound hydroxycinammic acids, and soluble phenolics such as phenolic acids, phenylpropanoids flavonoids and quinones. In this article, a method for extracting and analysing the soluble fraction of these phenolics, in different plants having the medicinal activity using spectrophotometer. The results show that the plants under the study contain high amount of phenolic compound content and hence are may be having the medicinal value. Out of all these plants Azadirecta indica has the maximum phenolic compounds in high contents.

Schinus molle L. (Anacardiaceae), also known as Brazilian pepper tree, is a tree which is short and has thin, long leaves and it is often used in subtropical climates for landscaping. Schinus spp. has been traditionally used as medicine by indigenous people throughout the tropics (Erazo et al., 2006). Recent research show that extracts obtained from S. molle can be used as an analgesic (painreliever), anti-inflammatory and anti-tumorous agent (Yueqin et al., 2003; Diaz et al., 2008). It also possessesial potent antibacterial, antiviral, antifungal, insecticidal and repellent properties (Dikshit et al., 1986; Chopa et al., 2006; Ferrero and Gonzales, 2006; Ferrero et al, 2007; Padin et al., 2007)

lignocellulosic material is one of the most abundant and renewable resource on earth for conversion to readily utilizable hydrolyzate conversion .Degradation of lignin is a prerequisite for rendering cellulose for action by cellulose hydrolyzing enzymes. While various pretreatments have been proposed for lignin degradation use of oxidizing agent such as inorganic oxidants ozone, per acetic acid and hydrogen peroxide has been reported as effective for lignin degradation and cellulose hydrolysis.It is proposed to employ mechanical disintegration of paddy straw followed by treatment with MnSO4 and H2O2 as they enhance the susceptibility of rice straw to enzymatic saccharification. To initiate the production of industrially important products from lignocellulosic biomass, bioconversion of the lignocellulosic components into fermentable sugars is necessary that could be used for ethanol production. Cellulomonas is known to produce both cellulases and hemicellulases and it is used for the saccharification . This present study reports on the microbial pretreatment and saccharification of the agricultural residues like rice straw (raw material) using a bacterial strain Cellulomonas fimi (MTCC-24) and ethanol production by Zymomonas mobilis.

Dyes are usually present in trace quantities in the treated effluents of many industries. The present study investigates the potential use of pretreated rice husk and rice husk ash for the removal of methylene blue from wastewater. A series of batch experiments were carried out to determine the influence of different system variables such as PH, dye concentration, adsorbent dosage and temperature. The similar experiment was conducted with commercially available powdered activated carbon, in order to evaluate the performance of rice husk carbon. The adsorption capacity of both rice husk carbon and activated carbon has been tested for decolourization of waste water containing methylene blue. For equilibrium studies, two isotherm models were used which is Freundlich and Langmuir for different temperatures and it was found that both Freundlich and Langmuir, fitted in the experimental data very well. Thermodynamic studies showed that the adsorption of methylene blue from rice husk is exothermic and spontaneous in nature.

In the advent of producing an effective tumour targeting drug system, Poly lactic acid-co-glycolic acid microspheres were formulated using Double (multiple) emulsion technique with and without human Ig G. The ideal ratio of drug to albumin was attained by varying the concentration of drug and this ideal batch of drug loaded microspheres was selected and subjected to physical characteristics such as size, shape and uniformity by size distribution analysis. All the test batches of microspheres were subjected to in-vitro evaluation and ideal batch of 5-Fluorouracil microspheres with and without monoclonal antibodies were subjected in-vivo evaluation for drug distribution and targeting efficiency by comparing with free 5-Fluorouracil. The results helped to arrive for a conclusion that the Fluorouracil immune-microspheres group was more effective than Fluorouracil microspheres and Fluorouracil groups but it will be worthwhile to investigate the anticancer activity of active targeting system by conjugating specific antibodies against to specific tumour antigen.

This study investigated the influence of eight-week volleyball game versus aerobic exercise interventions in mitigating of depression in the young people. The first 51persons from100 participates who had more depression score than others were determined. Participates (M age = 20.43, N = 51) were randomly assigned to one of three groups: volleyball program, aerobic and control group. Classes met 1 hour, 3 days per week, for 8 weeks. Beck Depression inventory was used to the individuals. Pre and post-test were used to the experimental and control groups. Results were analysis with ANOVA and it revealed decreases in depression over the intervention. Both groups benefited from the physical exercise intervention and there was no difference between the two experimental groups. These findings indicate that both type of the exercise can mitigate depression and that these result are not depend on the one of the two exercises.
