Association rule mining is the recent research area in data mining. Frequent Itemset Mining techniques is one of the prominent techniques in pattern mining. In this system frequent itemset mining is used to find the frequent amino acids patterns in Dengue Virus Type1 data set. This system uses an integration of Transaction Reduction and Random Sampling (TRRS) approach to identify the frequent patterns in Dengue Virus Type1 amino acids sequence. Our system reveals the association between the amino acids. Our System first identifies the number of amino acids sequences suitable for each transaction and finds the number of association rules using Transaction Reduction and Random Sampling methods by varying the sample size. Experimental results show that the performance of our proposed Transaction Reduction and Random Sampling Algorithm(TRRS) works efficiently when compared to Apriori algorithm, FP Growth algorithm, Two Dimensional Transaction Reduction(TDTR) Algorithm Improved TDTR algorithm, Set Oriented Mining (SETM) algorithm and Improved SETM Algorithm (ISETM) in terms of number of association rules generated and the time taken to generate...

Brassica campestris Linn. (yellow mustard), a common Indian condiment, possesses melatonin as an important antioxidant. Optimization of supercritical carbon dioxide extraction (SC-CO2) process parameters was conducted to obtain an extract having the best combination of yield of melatonin and maximum in vitro hypoglycaemic and hypocholesterolemic activities, along with a desirable balance of ω6 to ω3 fatty acids. A full factorial design and response surface methodology were employed for process optimization. Melatonin content of the extracts was obtained by high performance liquid chromatography and by liquid chromatography-mass spectrometry. The optimized extraction conditions were obtained at 300 bar, 50 °C for 120 min. This extract exhibited highest content of melatonin (660.72±41.05 ng/g of dry mustard powder), maximum in vitro hypocholesterolemic (60.11±3.89%) and hypoglycaemic (59.70±2.67µg/ml) activities and possessed minimum ω6 to ω3 (1.29) ratio with minimum erucic acid content (2.00±0.20 g/100g of fatty acid). The electron paramagnetic resonance spectroscopy of the extract (0.10±0.001 g/ml) showed 72.10±4.01% scavenging activity of DPPH radicals, establishing its strong antioxidant potency. A new Chrastil equation was developed...

The extraction of poly-β-hydroxybutyrate (PHB) and C-phycocyanin (C-PC) from Nostoc muscorum revealed that PHB yield after C-PC extraction was not found differ significantly as without C-PC extraction. Under photoautotrophic growth condition, the test cyanobacterium accumulates PHB and C-PC with a maximum yield of 40 and 57 mg l-1 respectively at the stationary phase, i.e. on day 21 of incubation. The most significant enhancement in C-PC yield up to 146 mg l-1 was recorded in 0.4 % fructose supplementation. High C-PC and PHB yield was observed in 0.4% fructose supplementation followed by 0.4% glucose supplementation. Here, in this study we show, that PHB yield after C-PC extraction was not affected significantly and C-PC yield was found enhanced under 0.4 % carbon source (fructose and glucose) supplementation. Significant Biomass and PHB yield depicted under supplementation of glucose, fructose, maltose and sucrose was due to boost in growth. Thus, present study demonstrates the extraction of both the products, i.e. PHB and C-PC is...

Aims and Objectives: The present study was conducted to find out morphometry of thyroid gland in different age groups. Material and Methods: The study was conducted on 60 human thyroid glands in the Department of Anatomy, Pt. B. D. Sharma, PGIMS, Rohtak in North Indian population. Results: In present study, mean length of right and left lobe of thyroid gland was found to be 29.88±7.03 mm and 29.45±5.44 mm in Group A, 41.33±6.95 mm and 38.87±5.04 mm in Group B, 35.02±3.98 mm and 31.77±3.27 mm in Group C respectively. The mean width was observed as 18.76±4.23 mm and 20.77±6.01 mm in Group A, 24.13±4.77 mm and 22.47±2.72 mm in Group B, 21.54±2.05 mm and 20.72±2.53 mm in Group C respectively in right and left lobes. The mean thickness was 13.70±4.69 mm and 13.60±4.51 mm in Group A, 15.19±1.99 mm and 15.01±2.29 mm in Group B, 14.73±1.99 mm and 14.09±2.33 mm in Group C respectively in right and left lobes. The mean length and height of the isthmus of thyroid...

Mental disorders are commonly occurring and often seriously impairing in many countries throughout the world. The total number of people suffering from anxiety or depression amount to 615 million, Close to 10% of the world’s population is affected. Chrysanthemum indicum is an ancient herbal medicine used as an anti-arthritic, anti-inflammatory and anti-anxiety in many Asian countries. The elevated plus-maze (EPM) and open field test has been most familiar tool in the investigation of the neurochemical transmission basis of anxiety, for testing anxiolytic drugs. The anxiolytic activities of Ethanolic and Chloroform extracts of Chrysanthemum indicum Linn flowers were evaluated using the elevated plus-maze (EPM) and Open field. The ethanolic extract results are suggestive of anxiolytic activity in dosages around 250 and 500 mg/kg, as expressed by elevation of the time spent on the open arms in the plus-maze; a decrease of freezing and increase of deambulation in the open field...
