Pharmacokinetic Parameters Determination of Gendarusin a in Men Subject Urine After Administration of Ethanol Extract of Justicia Gendarussa Burm. F. Leaf (Ethno Medicine Research)

Justicia gendarussa Burm. f (Famili: Acanthaceae) has flavonoid that inhibits hyaluronidase enzyme of spermatozoa in the fertilization process. Previous research reported that the major component of J.gendarussa was 6,8-di-L-arabinopyranosil- 4’,5,7-trihydroxy flavones or 6,8-diarabinosylapigenin (gendarusin A).Objective: This experimental study has been carried out to determine the pharmacokinetic parameters of gendarusin A in human urine after single oral administration of J.gendarussa extract. Methods: Six healthy men were enlisted in this study. Urine samples were collected at intervals for 24 hours before and after six healthy volunteers administrated orally 100 ml ethanol extract suspension of J. gendarussa leaves, containing 1 g of extract equal to 16,4 mg gendarusin A, for the measurement of gendarusin A by HPLC. Result: The calibration curve of gendarusin A peak areas (y) against the concentrations (x, μg/ml) in urine was linear and the regression equations was y = 34.3496x + 63.6315 (r = 0.9992). The lowest absolute recovery was 106.10 %, while the lowest assay recovery was 81.92 %, which revealed that the accuracy of the method was satisfied. All values of the R.S.D. of intra-day precision were less than 8,12 %. The LOD and LOQ of assaying gendarusin A in urine was 0.0817 μg/ml and 0.2724 μg/ml, respectively. Conclusion: Following oral administration of J.gendarussa extract suspension, the result show that the elimination half-lives (t ½) for gendarusin A in the urinary excretion were 2,44 – 8,53 hours (mean 4,44 ± 2,14 hours) and the rates constant of elimination (Kel) were 0,08 – 0,28 hour-1 (mean 0,18 ± 0,07 hour-1)

QUALITY BENCHMARKING IN BUSINESS PERFORMANCE USING SURVEYING TECHNIQUE – REVIEW

In today’s scenario every business organization will try to establish their own objectives/Goals for successful execution in every stage of business performance management system. Benchmarking plays a major role in today’s high competitive work culture in order to compare the actual performance or output against the known standards.  Using benchmarking tool we can assess the performance of business process by measuring the quality of resources, cost of resources, Market share assessment and customer satisfaction level etc are some of the factors which are strongly considered for evaluation. With the help of this tool we can find out the strength and weakness of the organization. In this paper attempt has been made to conduct survey analysis based on literature review information. The study is focused on the performance of engineering educational institutions in India with strong vision and mission statements. Hence a detailed survey form is designed using Google form applications with all parameters.</jats:p

Maximizing Machine Capacity by Improving Efficiency using Linear Programming Model

In the global manufacturing system, machine performance is considered to be one of the vital role in organization wellbeing. In specific analysing the capacity utilization of machines in each shift is a big challenging job in industrial organization. The primary importance is keeping the machines in uptime condition at the same time loading the jobs in machines decides the capacity usage of machines to do the useful jobs. In this paper focus is made on the capacity planning of machines in production shift. capacity utilization measures the actual capacity of machine with respect to the potential output within a specific period. In real situations if the demand for the product increases the production capacity also increases but at the same time if the demand falls capacity will also become very low. Hence in this work attempt has been made to develop a mathematical model for machine capacity planning using linear programming model solved by using LINDO software.</jats:p

New Insight into Sugarcane Industry Waste Utilization (Press Mud) for Cleaner Biobutanol Production by Using C. acetobutylicum NRRL B-527

In the present study, press mud, a sugar industry waste, was explored for biobutanol production to strengthen agricultural economy. The fermentative production of biobutanol was investigated via series of steps, viz. characterization, drying, acid hydrolysis, detoxification, and fermentation. Press mud contains an adequate amount of cellulose (22.3%) and hemicellulose (21.67%) on dry basis, and hence, it can be utilized for further acetone-butanol-ethanol (ABE) production. Drying experiments were conducted in the temperature range of 60–120 °C to circumvent microbial spoilage and enhance storability of press mud. Furthermore, acidic pretreatment variables, viz. sulfuric acid concentration, solid to liquid ratio, and time, were optimized using response surface methodology. The corresponding values were found to be 1.5% (v/v), 1:5 g/mL, and 15 min, respectively. In addition, detoxification studies were also conducted using activated charcoal, which removed almost 93–97% phenolics and around 98% furans, which are toxic to microorganisms during fermentation. Finally, the batch fermentation of detoxified press mud slurry (the sample dried at 100 °C and pretreated) using Clostridium acetobutylicum NRRL B-527 resulted in a higher butanol production of 4.43 g/L with a total ABE of 6.69 g/L.Peer reviewe

Recent Advances in Sugarcane Industry Solid By-Products Valorization

Sugarcane is among the leading agricultural crop cultivated in tropical regions of the world. Industrial processing of sugarcane generates sugar; as well as various solid wastes (i.e. sugarcane bagasse, pressmud). Improvement of biotechnology in industrial level, offers opportunities for economic utilization of these solid residues. In the last few decades, sugarcane bagasse and pressmud have been explored in the theme of lignocellulosic bioconversion. The recalcitrance of biomass is a major drawback towards successful exploitation of lignocellulosic residues. Pretreatment by suitable/efficient processes can overcome this limitation. In this regards; physical, chemical and biological treatment systems are brought into our perspective. Chemical and physicochemical methods are capital-intensive but not environment-friendly, in contrast, method like biological treatment is eco-friendly but extremely slow. There are still major technological and economic challenges need to be addressed; e.g. bioprospecting, established more reliable genetically modified microorganisms, upgrade gene cloning and sequencing processes, yield improvement at large scale etc. Productions of value-added products from these solid wastes are discussed in such a way that pinpoints the most recent trends and the future directions. Biofuels, enzymes, organic acids and bio-sorbents production draw a clear sketch of the current and future bio-based products. Nano-biotechnology and genetic engineering could be future trends to improved processes and products. This review serves as a valuable reference material for a wide range of scientists and technologists in the relevant fields
