Physical parameters such as pH and temperature influencing dimethoate biodegradation by Pseudomonas sutzeri
Current study is based on biodegradation of organophosphorus pesticide dimethoate in liquid MSM medium with P. sutzeri. It was found to be capable of utilizing dimethoate as sole carbon and energy source and could rapidly utilized dimethoate beyond 100 ppm and showed maximum growth in MSM. The concentration of the dimethoate in the solution decreased exponentially with the increased exposure time. P. sutzeri could tolerate dimethoate from 100 ppm to 900ppm. In current study, several factors influencing dimethoate degradation were investigated. Complete disappearance of dimethoate was detected within 72 h of incubation. UV-Visible spectroscopic analysis (660 nm) revealed the complete mineralization of dimethoate. The optimal pH and temperature growth conditions were 8.5 and 30°C, respectively. The microbial consortia could prove to play a valuable role for the bioremediation of dimethoate contaminated field soil

EVALUATION OF LEUCAS ASPERA WHOLE PLANT EXTRACTS FOR DIURETIC AND LAXATIVE PROPERTY
ABSTRACTObjective: This study was undertaken to investigate diuretic and laxative potency of Leucas aspera whole plant.Methods: The dried whole plant (leaves, stems, and flowers) material was subjected to extraction by continuous hot percolation method. Inevaluation of diuretic activity male albino rats were used as the experimental animals. The first group of animals, serving as control, received normalsaline (25 ml/kg, post-operative); the second group received furosemide (10 mg/kg, post-operative) in saline. Other groups received doses of extract(200-400 mg/kg) in normal saline. The parameters determined were total urine volume, the concentration of Na(chloride) in the urine. Na+ and K+ concentrations were determined by flame photometer, and Cl−+(sodium), K concentration was estimated by titrimetric method.Laxative activity was also studied using male albino rats. The animal groups were administered orally either with vehicle (1% Tween-80 solution innormal saline, 25 ml/kg), reference standard drug, agar-agar (300 mg/kg, post-operative) in saline or doses of extract (200-400 mg/kg). After 8 h ofdrug treatment, the feces were collected and weighed.Results: This study revealed that L. aspera whole plant extracts possesses significant diuretic and laxative activity in comparison with the standarddrugs. The activity may be due to the chemical constituent present in the plant parts. The further studies may be taken up to isolate these activeconstituents.Conclusion: L. aspera whole plant possesses diuretic and laxative property since it contains a variety of phytoconstituents.Keywords: Leucas aspera, Diuretics activity, Lipchitz method, Laxative activity, Furosemide, Agar-agar.+(potassium), and Clâˆ
Solitary fibrous tumor of nasal cavity: a rare case report with review of literature
Solitary fibrous tumor is an unusual soft tissue neoplasm. Commonly the tumor is located in pleural cavity but recently has been described in many extra-thoracic locations. Nose and paranasal sinuses are rare sites for this tumor and so far less than 30 cases have been reported in the literature. In the nasal cavity the tumor usually presents as a polypoidal intranasal mass in a middle aged patient. Erosion of adjacent structures may occur but tumor does not metastasize. Local excision is almost invariably curable. We report SFT in a 50 year old patient with involvement of unilateral nasal cavity and all paranasal sinuses
Development of sportswear with enhanced moisture management properties using cotton and regenerated cellulosic fibres
The effect of fibre composition on moisture management properties and peak heat flux (qmax) values of one commercialsport garment and six knitted fabrics (sportswear), composed of 100% polyester, 100% cotton, 100% modal, and blend ofpolyester with cotton and modal, have been investigated. The moisture management properties are assessed by using themoisture management tester, and the feeling of coldness or warmth is assessed by measuring qmax value on KES-F7 Thermolabo II. Blending polyester fibre with cotton and modal has improved moisture management properties of the fabrics incomparison to 100% polyester fabric. qmax study also indicates that polyester/cotton and polyester/modal blend fabrics arecooler as compared to 100 % polyester fabric
Interpretive Structural Modelling for Challenging Issues in JIT Supply Chain: Product Variety Perceptive
The success of JIT in Japan inspired many organizations to adopt JIT to the supply chain in order to reduce the waste and cost. These organizations have to face inherent challenging issues and complexities while implementing JIT concepts in supply chain. The manufacturer must be in position to identify challenging issues, its consequences so as to design a robust and reliable supply chain accordingly otherwise the manufacturing system may not provide the desired results. The focus of this paper is on the significant challenging issues in JIT supply chain from product variety perspective. Some challenging issues act as driver for sustainable implementation of JIT supply chain. For adoption of JIT supply chain, significant issues must be identified, analysed and discussed. In this research, study factors are the challenging issues for sustainable JIT supply chain implementation. Authors have identified ten significant issues from literature review. The main objectives are to identify and rank the challenging issues for implementation, to develop and to analysed the interaction between identified challenging issues using ISM and to prepare a framework for successful JIT supply chain implementation
Study of interleukin-6 levels in early diagnosis of neonatal sepsis
Background:Neonatal septicemia is one of the commonest causes of neonatal mortality and morbidity. Interleukin-6 Levels appears to be one of the most promising candidate cytokine for early diagnosis of neonatal septicaemia. The aim and objectives of this study was to study the role of IL-6 levels as an early marker for diagnosis of neonatal sepsis and to compare IL-6 levels with other septic markers.  Methods:This is a hospital based prospective study to evaluate the efficacy of IL-6 as an early diagnostic marker of neonatal sepsis. Eighty neonates, delivered in the hospital, having risk factors for neonatal sepsis, along with those coming to hospital with signs and symptoms of sepsis up to 28 days of life (as study group ) along with normal new-borns admitted to the postnatal ward without high risk factors (control group) were enrolled for this study.Results:IL-6 Levels has shown maximum sensitivity of 95.83%, specificity of 87.50%, positive predictive value of 92%, negative predictive value of 93.33% and accuracy of 92.50 %. E. coli was the most common organism responsible for sepsis. CRP was reported to be highly sensitive (84.21%), and CBC was highly specific (75.00%), IT ratio has sensitivity of 62.5% and specificity of 56.25% while micro-ESR has shown sensitivity of 50.0% and specificity of 62.5%. Out of 80 cases, blood culture (BacTalert) showed growth in 48 cases in study group while two cases in control group. Thus blood culture positivity was 60%.Conclusion:IL-6 test has maximum sensitivity as well as specificity in comparison with other septic markers. Blood culture is the gold standard for the diagnosis of septicemia. CRP is most sensitive while CBC is most specific marker in neonatal sepsis.
