Long-lasting UV protection and mosquito repellent finish on bamboo/tencel blended fabric with microencapsulated essential oil

In this study , bamboo/tencel 50:50 blended fabric has been used for microencapsulation finishing by essential oil combination using exhaustion method in order to enhance the wash durability of the fabric. The three shell materials, namely sodium alginate, Acacia arabica and Moringa oleifera gum and three core materials like thyme oil, cypress oil and grapefruit oils in combination of 2:1:1 have been used. Then the fabrics are tested for functional properties like UV protection and mosquito repellency, and also the fabric is analyzed for allergic test. The result shows that the Moringa oleifera shell finished fabric has very good activity in both the functional property and there is no allergic reaction found. The durability can also be achieved up to 30 washes by using Moringa oliefera gum material as compared to other two

A study of knowledge, attitude and practice in diabetic retinopathy among patients attending a primary health care centre

Background: Diabetic retinopathy is a major cause of preventable blindness. Sufficient knowledge about the disease can prevent sight threatening complications. Aim of this study is to evaluate the knowledge and its influence on attitude and practice in diabetic retinopathy among patients attending a primary health centre.Methods: A knowledge attitude practice questionnaire was prepared and pretested in a sample group of representative population. The response was analyzed as to whether the questions were understood or not. Social workers were trained in administering questionnaire. Diabetic patients were given questionnaires at primary health centre and filled in the presence of social workers.Results: Out of 324 patients 60.8% had no knowledge of diabetic retinopathy compared to 39.19% who had knowledge (p <0.001). Knowledge was more in age <40 years (82.60%) and least in 51-60 years (29.34%) (p<0.001) and more among females (38.59%) than males (61.4%). Knowledge was significantly higher among upper socioeconomic group (77.8%). About 83.46% in knowledge group had right attitude which was significantly higher than non knowledge group (32.48%) (p<0.001).  42.51% in knowledge group had practice of visiting ophthalmologist for eye check-up which was significantly higher than non knowledge group (13.19%) (p<0.001).Conclusions: The attitude and practice of diabetic retinopathy was statistically significant in knowledge group compared to those who had no knowledge of diabetic retinopathy. Improving knowledge about diabetic retinopathy through awareness campaigns can increase attitude and practice. Early detection can help in preventing sight threatening complications of diabetic retinopathy

Studies on lipase enzyme production by indigenously isolated Bacillus Cereus (BAIT GCT 127002 ) and Bacillus Cereus (BAIT GCT 127001)

Microbial lipases holds a prominent place among biocatalysts that act on carboxylic ester bonds.Â&nbsp; This present study involves about eight strains isolated form slaughter house waste water,Coimbatore producing lipase.Among those strains , two bacterial strains exhibiting high lipase productionÂ&nbsp; were identified asÂ&nbsp; Bacillus Cereus (BAIT GCT 127002 ) and Bacillus Cereus (BAIT GCT 127001 ) by both biochemical analysis and 16S rRNA sequencing.Â&nbsp; Initial studies were done for optimizing lipase production using many components such as time course,Carbon sources ,pH and innoculum volume whichÂ&nbsp; revealed maximum lipase acitivity (43.37 U/ml) at 24 hours, usingÂ&nbsp; palm oil , at pH 8 and innoculum volume of 1 ml by Bacillus Cereus (BAIT GCT 127002 ).Further the percentageÂ&nbsp; removal of oil from oil stained fabric was determined using partially purified lipase with or without detergents and the results indicated 20% ,30% removal with use ofÂ&nbsp; crude lipase and commercial detergent respectively.Hence, lipase from Bacillus Cereus(BAIT GCT 127002 ) Â&nbsp;Â&nbsp;can be regarded as an ideal ingredient that can be used in the laundry detergents.Â&nbsp

A study on the antimicrobial property of the cotton fabric imparted with Michaelia champaca leaf extract loaded nanoparticles

In the present work ethanol, methanol, ethyl acetate, chloroform and benzene extract of the Michaelia champaca leaves were screened for their antimicrobial activity. The ethanolic extracts of M. champaca leaves were proved to have the maximum antimicrobial activity; thus the ethanolic leaf extract was selected and the nanoparticles were synthesized using ionic gelification method. The nanoparticles were characterized physically and chemically using TEM and FTIR respectively. The herbal extract loaded nanopartricles were coated on to the non woven cotton fabric using the pad dry cure method. The antimicrobial activity of the untreated and treated (M. champaca leaf extracts coated fabric and leaf extract loaded nanoparticles coated fabric) fabric were assessed by the standard AATCC 147, AATCC 30 and laundering durability. The herbal leaf extract loaded nanoparticles coated fabric showed the better antimicrobial activity and particularly highest wash durability when compared with other treated fabric. The controlled and sustained releasing property of the herb extract loaded nanoparticles could be attributed to its very effective antimicrobial activity. These particles could further have numerous applications in the field of medical textiles. The study revealed that the fabric coated with herbal extract loaded nanoparticles could act against microorganism in the fabric

Ethanolic Noni ( Morinda citrifolia

Antioxidant and antimicrobial activities of ethanolic noni leaf extract (ENLE) without and with chlorophyll removal by sedimentation method were comparatively investigated. Total chlorophyll content was reduced by 82% in the top fraction (CR-ENLE) collected after 24 h at 4 °C as compared to that of ENLE. Antioxidant and antimicrobial activities were lower in the bottom fraction rich in chlorophyll (Chlo-ENLE) than others (P < 0.05). Based on the microbiological limit, the shelf-life of striped catfish slices pre-treated with 400 mg kg⁻¹ C-R-ENLE was extended to 9 days as compared to the 3 days recorded for the control (without pre-treatment). Slices treated with CR-ENLE had lower lipid oxidation than those treated with ENLE during refrigerated storage (P < 0.05). The sedimentation process was therefore a potential green method for producing ENLE having improved antioxidant and antimicrobial activities without green colour. It can be used as a natural additive for shelf-life extension of fish slices
