Majority of microbial infections occurring in the human body are attributed to be biofilm-mediated. Biofilms formations in industrial settings are associated with many problems. Formation of biofilm is controlled by environmental factors. This study is carried out to determine the biofilm formation in Serratia marcescens under different environmental condition. Biofilm assay in nutrient medium by microtitre plate methods under different test conditions were performed.

Cyphostemma setosum is a traditional medicinal climber, distributed in Palani hills, the Western Ghats, Tamil Nadu, India. In this region, the puliah tribal community is using this species more commonly to control type II diabetics. As there is no work in this line, the present study was carried to investigate the in vitro antidiabetic activity of C. setosum in terms of the level of inhibition of α-amylase and α-glucosidase as influenced by methanolic extract of aerial parts of this species.

Buerger’s disease is a chronic disorder, also known as Thrombo- AngitisObliterance (TAO). It is a nonatherosclerotic, segmental inflammatory disease that most commonly affects the smalland medium-sized arteries and veins in the upper and lower extremities. It frequently occurs in cigarette smokers. Poor hygiene, genetic factors, autonomic over-activity are other factors for this disease. Buerger’s disease presents with rest pain, intermittent claudication, discoloration and gangrene formation.

Cotton fabric was finished with lab prepared silicone finish (F1). It was developed and applied on cotton fabric by pad-dry-cure method for enhancing water absorbency and antibacterial activity. Untreated (F0) and treated (F1) cotton fabric samples were tested for water absorbency using water drop put on the fabrics and recorded the absorption time, by standard test method AATCC Test Method 79-2007 and the antibacterial activity against staphylococcus aureus by AATCC test method 90-2011. Physical properties: stiffness, crease recovery angle and tensile strength were also evaluated.

The major open drainage sanganour oodai system, Which has intricate linkage with storm water supply domestic sewage and industrial effluent disposal, water samples from collected and analyzed for physical-chemical parameters to assess the water quality of the Sanganur oodai systems. The study revealed that physical-chemical parameter like PH,EC,TDS,DO,BOD,COD, and the effect of the effluent on the crop plant (Capsicum annum ) has been investigated the days of emergence, germination percentage ,shoot length, root volume, biochemical parameters ,protein, carbohydrates , and.

The antimicrobial activity of whole plant extracts of Malaxis rheedei Sw was evaluated in vitro, using disc diffusion method. Four different extracts were used which included chloroform, methanol, ethyl acetate and petroleum ether. Five species of bacterial strains namely Acinetobacter baumannii, Pseudomonas aeruginosa, Staphylococcus aureus, Salmonella typhi, Klebsiella pneumoniae and fungus strains Aspergillus flavus, Trichophyton rubrum, Candida albicans, Candida tropicalis, Cryptococcus neoformans were used for the present study.

The present study was aimed for scientific evaluation of the antiinflammatory activity of ethanol extract of Aristolochia bracteata Retz whole plant by in vivo carrageenan induced paw edema model in albino rats. Ethanol extract showed dose dependent antiinflammatory activity. The ethanol extract has shown a significant (p< 0.001) percentage inhibition of paw edema 80.79% and 87.70% on 3 hour at 200 and 400 mg/kg respectively. The study was compared with standard drug indomethacin 85.11% (10mg/kg).

Handlings and transport of fish are the most stressful procedures in aquaculture. The anesthetic efficacy of two types of natural anesthetics in both forms of powder and oil were evaluated on young common carp (Cyprinus carpio L.) with the mean weight of 60±10g for handling and health management experiments. These works were conducted in the laboratory of fish research in the Department of Animal production, Faculty of Agricultural Sciences at University of Sulaimani. The study included three experiments.

Electroplating is considered a major polluting industry because it discharges toxic materials and heavy metals through waste water, air emissions and solid wastes in environment. It was found that a large amount of metals and chemicals is disposed into main stream without treatment as they have no effective measures for treatment or recovery of metals in unorganized sectors. The biochemical components like protein, carbohydrate and lipid were estimated quantitatively in the tissues of gill, liver, kidney and muscle of control and electroplating effluent treated fishes.

Histopathological changes have been widely used as biomarkers in the evaluation of the health of fish exposed to contaminants, both in the laboratory and field studies. One of the great advantages of using histopathological biomarkers in environmental monitoring is that this category of biomarkers allows examining specific target organ including liver that are responsible for vital functions. Alternations found in these organs are normally easier identifying than functional ones.
