GOING GREEN: AN ECOFRIENDLY DRIVE FOR THE SUSTAINABLE FUTURE
We enter our office building and go straight to the parking lot. What do we get to see there? Parking is not allowed in the basement. Just to increase vegetation. Not only this, there are preferred car parking areas for car pooling vehicles and recharge stations for alternative fuel vehicles. Now imagine this! Our office uses sensitive air conditioners that automatically alter the room temperature depending upon the number of people in the room. It also uses eco-friendly paint on walls. The structure of the building is in such a way that it uses 95 per cent natural light. Well, don‟t be surprised we are simply working in a green environment!
HAZARDS OF MERCURY POISONING & PREVENTION STRATEGIES
In the long history of water pollution, the Minamata incident was unique. The mystery of the existence of methylmercury in sea fish was baffling at first since the source was inorganic mercury compound discharged into the Bay by the Minamata chemical company (Japan). The missing link between inorganic mercury in Bay water and methyl mercury in sea fish was bridged only after extensive research since the 1950s. This is the first known case where the natural bioaccumulation (in fish) of toxic material (methyl mercury) killed about hundred people and genetically damaged a large population

PERILS OF ELECTRONIC WASTE: ISSUES AND MANAGEMENT STRATEGIES
Electronic waste or e-waste is one of the most popular growing issues of the world. The term e-waste is for the collection of old discarded computers, TVs, Refrigerators,, radios – basically any electrical or electronic appliance that has reached its end-of-life. While e-waste contains both valuable materials such as gold, palladium, silver and copper, it also contains harmful metals like lead, cadmium and mercury. In the absence of suitable techniques and protective measures, recycling e-waste can result in toxic emissions to the air, water and soil and pose a serious health and environmental hazard. In India, e-waste is mostly generated in large cities like Delhi, Mumbai and Bangalore. In these cities a complex e-waste handling infrastructure has developed mainly based on a long tradition of waste recycling. But the problem is that these recycling processes are extremely harmful and have negative impacts on the worker‟s health and the environment.
TRANSDERMAL DRUG DELIVERY SYSTEM: A REVIEW
Today about 74% of drugs are taken orally and are found not to be as effective as desired. To improve such characters transdermal drug delivery system was emerged. The transdermal route of drug delivery has attracted researchers due to many biomedical advantages associated with it. However, excellent impervious nature of skin is the greatest challenge that has to be overcome for successfully delivering drug molecules to the systemic circulation by this route. Drug delivery through the skin to achieve a systemic effect of a drug is commonly known as transdermal drug delivery and differs from traditional topical drug delivery. The development of transdermal drug delivery systems is a multidisciplinary activity that encompasses fundamental feasibility studies starting from the selection of a drug molecule to the demonstration of sufficient drug flux in an ex vivo and/or in vivo model the fabrication of a drug delivery system that meets all the stringent needs that are specific to the drug molecule (physicochemical and stability factors), the patient (comfort and cosmetic appeal), the manufacturer (scale-up and manufacturability), and most important, the economy. This review article provides an overview of TDDS, its advantages over conventional dosage forms, drug delivery routes across human skin, penetration enhancers, various components of Transdermal patches, types of Transdermal patches.
STUDIES ON THE ISOTHERMS, KINETICS AND THERMODYNAMICS OF ADSORPTION OF CRYSTAL VIOLET ON LOW COST MATERIALS
The low cost adsorbent namely Cassia Siamea (CS), Albizia Labbeck (AL), Nerium Indicum (NI), Durauta Erecta (DE), and Potato Husk (PH) have been tested for the effectiveness in declourisation of wastewater containing a crystal violet dye (CV) by an adsorption technique. The various parameters such as contact time, dye concentration, temperature, adsorbent dosage, pH and ionic strength were applied for the study. The equilibrium was attained within 50 min, the adsorption of the dye on solution was studied in the pH range 2-7, the salt dosage was increased from 0.05 to 0.5 g. Adsorption was carried out at different temperature in the range of 293 to 333 K±0.5K It was observed that the adsorption increase with increasing in time, solution pH and dosage (g). It was also observed that adsorption decreases with increase in CV concentration and the addition of salt. The kinetic data were then fitted using both Pseudo –first order model and second order model, Langmuir and Freundlich models were often used to describe equilibrium adsorption isotherms and the thermodynamic parameters, change in enthalpy (ΔH) (KJ/mol) and change in entropy (ΔS) (J/mol) which related to the Gibbs free energy (ΔG).
EVALUATION OF TESTICULAR TOXICITY OF BUTACHLOR (A CHLOROACETANILIDE HERBICIDE) IN RATS
Butachlor, a chloroacetanilide herbicides, widely used in agriculture by farmers was evaluated to determine its effects on testes of rats. Oral administration of butachlor at dose level of 200 mg/kg b.wt./day for 30 day leads to alterations in the testes. Haematological studies showed decrease in erythrocyte count, haematocrit and haemoglobin levels while an increase was noticed in leukocytes count, blood urea and blood sugar. The weight of testes and accessory sex organs decreased significantly. Butachlor administration brought about marked reduction in sperm counts. A significant reduction in glycogen and sialic acid and an increase in protein and cholesterol content of testes were noticed. Histological examination revealed shrunken seminiferous tubules exhibiting loosened epithelium and reduced number of spermatozoa. Fertility test showed 90% negative fertility in treated rats. In addition, acid phosphatase enzyme activity increased significantly whereas alkaline phosphatase enzyme activity showed sharp decline. It also suppressed testosterone, FSH and LH levels significantly. In conclusion, butachlor has deleterious effects on male reproduction.

EFFECT OF OXALIS CORNICULATA WHOLE PLANT EXTRACTS ON FERTILITY REGULATION IN FEMALE ALBINO RATS
Aim of the present study is to find out novel fertility regulation agent from natural products. Petroleum ether and ethanol extract of whole plant of Oxalis corniculata (Oxalidaceae) were tested for fertility regulation studies in female albino rats at the dose level of 10 and 20 mg petroleum ether and ethanol extract per 100 gm body weight administered orally from day 1-7 of pregnant rats for antiimplantation activity and also for immature ovariectomised rats for estrogenic/antiestrogenic activity. The dose level of 10 and 20 mg of petroleum ether extract inhibited 39.71% and 76.42% implantation sites respectively. Similarly, 10 and 20 mg of ethanol extract treatment has resulted in 27.87% and 38.21% inhibition of implantation respectively. In estrogenic activity, the uterus of treated rats showed significant increase in the gravimetric and micrometric measurements, indicating its estrogenicity. When both the extracts were tested in immature rats the estrogenic activity has been confirmed by early opening of vagina, cornification of vaginal epithelial cells and increase in uterine weight. Antiimplantation activity of O. corniculata is due to its estrogenic nature, therefore, it may be concluded that both the activities revealed their possible fertility regulation.

Cyclin dependant kinase-2 (CDK-2) is a key regulator of cell cycle progression and glycogen synthase kinase-3 (GSK3) that plays a critical role in the regulatory pathway of serine/threonine kinase, which is being targeted for the treatment of human cancer. The natural product of 1, 2 disubstituted idopyranose (C23H28O12) was isolated from the leaves of the medicinal plant, Vitex negundo to treat human cancer. The bioactive compound of functionalized 1, 2 disubstituted idopyranose was studied through molecular docking and evaluated for their inhibitory activity against CDK2 and GSK3 using GLIDE module and also ADME/T properties of the analog was analyzed using QikProp module. Based on the docking studies, we have identified some key features in the 1, 2 disubstituted idopyranose that is responsible for simulations of a promising lead compound for the inhibition of CDK-2 and GSK-3 inhibitory activity. The 1, 2 disubstituted idopyranose, which showed docked energy -33.82 kcal/mol demonstrated against CDK-2 (2c4g) and docked energy -55.94 kcal/mol demonstrated against GSK-3 (3f7z). A series of 1, 2 disubstituted idopyranose demonstrated good inhibition against CDK-2 and GSK-3 and are useful candidates as leads for the development of potential anti-carcinogenic agents.
SPECTROPHOTOMETRIC AND CHROMATOGRAPHIC DETERMINATION OF ACETYLSALICYLIC ACID AND CAFFEINE IN PURE AND IN TABLET DOSAGE FORM
In the present research paper, spectrophotometric and chromatographic assay method has been developed for the simultaneous estimation of acetylsalicylic acid and caffeine in bulk and commercial tablets. Acetylsalicylic acid and caffeine showed absorbance maxima at 228 and 275 nm in 0.1N HCl and at 225 and 272 nm in methanol, respectively. These drugs were estimated in formulations by simultaneous equation method (method A) and absorbance ratio method (method B). Acetylsalicylic acid and caffeine at their respective λmax followed Beer-Lambert’s law at concentration range of 0-28 and 0-1.6 μg/mL. Method B involved measurement of absorbance at isoabsoptive point of these two drugs i.e. at 244 nm in 0.1N HCl and at 240 nm in methanol respectively.
ANALYSIS OF EFFLUENTS RELEASED FROM RECYCLED PAPER INDUSTRY
Waste Water and nearby soil samples of recycled paper industry are collected from Northern districts of UP viz. Saharanpur, Muzaffarnagar & Meerut and analyzed for various parameters like pH, TDS, TVS, TSS, TFS, TRC, TS, BOD, COD, Chloride, DO. The inferences were drawn on the basis of analysis. The very high absorbance in the region 200-300nm value suggests that these effluents are not fit to be disposed to the water stream as these effluents will result in increase of organic load in water streams. The present manuscript reports the investigation of the characteristics of effluents released from recycled paper mills of UP state to access the pollution load of recycling paper mills on the environment.
APPLICATION OF POLY-3 (METHYL THIOPHENE)-SAWDUST NANO COMPOSITE FOR REMOVAL OF ANIONIC CARMOISINE DYE FROM AQUEOUS SOLUTIONS
In this study the adsorption behavior of sawdust (SD) coated with poly-3 (methyl thiophene) as a synthetic adsorbent (P3MTh/SD) for separation of carmoisine (an anionic dye) from water solutions was investigated. The morphology of sorbents was studied by scanning electron microscopy (SEM). Various experiments have been carried out using batch adsorption technique to study the effects of the main parameters such as contact time, initial dye concentration, pH, dye solution temperature on the adsorption process. The results showed that the adsorption attained to equilibrium in 60 min. Isotherm study conformed well to Freundlich equation and the monolayer sorption capacity obtained from the Langmuir model was 2.77 and 21.64 mg/g for SD and P3MTh/SD, respectively. The kinetic studies indicated that the adsorption of carmoisine on both sorbents follows pseudo-second order kinetic. From thermodynamic studies, it was observed that the adsorption was spontaneous and endothermic. P3MTh/SD was found to be very effective adsorbent in wastewater treatment for removal of carmoisine dye.

RESPONSE SURFACE METHODOLOGICAL APPROACH TO OPTIMIZE THE NUTRITIONAL PARAMETERS FOR ENHANCED PRODUCTION OF LIPOPEPTIDE BIOSURFACTANT IN SUBMERGED CULTURE BY B. SUBTILIS SPB1
Nutritional requirements can contribute considerably to the production cost and the bioprocess economics. Media optimisation using response surface methodology is one of the used methods to ameliorate the bioprocess economics. In the present study, biosurfactant production by Bacillus subtilis SPB1 was effectively enhanced by response surface methodology. A Plackett–Burman-based statistical screening procedure was adopted to determine the most important factor affecting lipopeptide production. Eleven variables are screened and results show that glucose, K2HPO4 and urea concentrations influence the most biosurfactant production. A Central Composite Design was conducted to optimize the three selected factors. Statistical analyses of the data of model fitting were done by using SPSS and NemrodW software packages. Results show a maximum predicted biosurfactant concentration of 2.93 (±0.32) g/l, when using 15 g/l glucose, 7.5 g/l urea and 1 g/l K2HPO4. The predicted value is approximately 1.65 much higher than the original production determined by the conventional one-factor-at-a-time optimization method.
INFLUENCE OF GROWTH PARAMETERS ON BIODELIGNIFICATION OF EUCALYPTUS TERETICORNIS BY SCHIZOPHYLLUM COMMUNE
Pulp and paper industry use different chemicals to separate cellulose fibre from lignocellulosic biomass for papermaking. The use of sodium sulphide and chlorine during pulping and bleaching processes, have now been classified as the main sources of air and water pollution in the pulp and paper industry. To surmount these problems biological processing, offers potential opportunities for changing the industry towards more environment friendly industry. In the biological pulping process, removal of lignin can be achieved through treatment of lignocellulosic materials with white rot fungi due to their ability to degrade complex and recalcitrant organic molecules and this makes them attractive micro-organism for biodelignification. In the present study biological pre-treatment of Eucalyptus chips was carried out with Schizophyllum commune. The influence of growth parameters like incubation periods, moisture levels, media, media concentration, pH and temperature were also optimized. During the study it was found that Schizophyllum commune shows 14.72% lignin loss within 28 days at optimum conditions i.e. pH (6.0), temperature (250C), moisture (60%) and molasses concentration (4%). Thus the study will provide an insight to find out economically feasible conditions to commercialize biopulping on large scale.
IN- VIVO EVALUATION FOR ANTHELMINTIC EFFECT OF ALKALOIDS EXTRACTED FROM THE STEM BARK OF AFZELIA AFRICANA IN RATS
The anthelmintic activity of alkaloid extracted from the stem bark of Afzelia africana was evaluated in-vivo in rats experimentally infected with Nippostrongylus braziliensis. The alkaloids was obtained after partitioning the crude methanolic extract of the plant powdered material in petroleum ether, chloroform and N-butanol as solvent and subsequently subjecting them to phytochemical screening to identify the portions with the highest concentration of alkaloids which was then used in the study. The phytochemical screening shows that the amount of alkaloids was higher in chloroform and N-butanol portions. The anthelmintic activity was assessed by comparing the number of worms recovered from rats treated with the fractions to those from non-treated infected controls.
