Suspension model blood flow through an inclined tube with an axially non-symmetrical stenosis
Chakraborty, Uday Shankar,Biswas, Devajyoti,Paul, Moumita 한국유변학회 2011 Korea-Australia rheology journal Vol.23 No.1
The flow of blood in an inclined artery with an axially non-symmetrical but radially symmetrical mild stenosis has been presented in this study. To account for the slip at stenotic wall, hematocrit and inclination of the artery, blood has been represented by a particle-fluid suspension. The expression for the flow characteristics, namely, the impedance (resistance to flow), the wall shear stress and the shear stress at the throat of the stenosis have been derived and represented graphically with respect to different flow parameters. The impedance increases with the hematocrit and stenosis size but decreases with slip at wall and angle of inclination of the artery. The shear stress at the maximum stenosis height increases with the inclination of the artery but possess the characteristics similar to that of impedance with respect to other parameters. As an application, theoretical values of effective viscosity computed with the help of the present analysis are compared with experimental results and found that they are in reasonable agreement for low hematocrit values in small blood carrying vessels.

The present study focused on the establishment of micropropagation protocol for the high value Pluchea (P.) indica (L.) Less., genotype, an important medicinal plant and evaluation of the diuretic activity of the leaf extract of the tissue cultured plant. Leaf explants, nodal segments and shoot tips were cultured in MS medium supplemented with auxin and cytokinin and their combinations. With the objective of inducing callus giving rise to new adult plants, naphthalene acetic acid was found to be most effective for (80%) for callus induction. The methanolic extract of leaves of the micropropagated P. indica was investigated for its diuretic activity in Wistar albino rats. Urinary excretion parameters were studied for evaluation of diuretic activity using Frusemide (20 mg/kg, p.o.) as standard. The extract showed significant diuretic activity at the doses of 100, 200 and 300 mg/kg. p.o. An oral acute toxicity study for the extract was carried out and the $LD_{50}$ value was found to be 2,825 mg/kg body weight.

An Efficient Compression Algorithm for Forthcoming New Species
Subhankar Roy,Sudip Mondal,Sunirmal Khatua,Moumita Biswas 보안공학연구지원센터 2015 International Journal of Hybrid Information Techno Vol.8 No.11
Genomic repositories gradually increase individual and reference sequences, which shares long identical and near-identical strings of nucleotides. In this paper a lossless DNA data compression technique called Optimized Base Repeat Length DNA Compression (OBRLDNAComp) has been proposed, based upon redundancy of DNA sequences. For easy storage, retrieval time reducing and to find similarity within and between sequences compression is mandatory. OBRLDNAComp searches long identical and near-identical strings of nucleotides which are overlooked by other DNA specific compression algorithms. This technique is an optimal solution of longest possible exact repeat benefits towards compression ratio. It scans a sequence horizontally from left to right to find statistic of repeats then follow substitution technique to compress those repeats. The algorithm is straightforward and does not need any external reference file; it scans the individual file for compression and decompression. The achieved compression ratio 1.673 bpb outperforms many non-reference based compression methods.

Hypoglycemic and antihyperglycemic activity of leaf extract of pluchea indica Less
Pramanik Kartick Chandra,Bhattacharya Plaban,Biswas Ria,Bandyopadhyay Durba,Mishra Moumita,Chatterjee TK Kyung Hee Oriental Medicine Research Center 2006 Oriental pharmacy and experimental medicine Vol.6 No.3
The hypoglycemic and antihyperglycemic activity of methanolic extract of Pluchea indica Less. (Asteraceae) (MEPI) leaves were studied in normal rats and in streptozotocin induced diabetic rats respectively. The blood glucose levels were measured at 1, 4, 8, 16 and 24 h intervals after the treatment. The MEPI leaves showed reduction in blood glucose level in normal (35.12% and 36.01 % for 200 and 400 mg/kg, p.o. respectively) and in steptozotocin induced diabetic rats (36.10% and 41.87% for 200 and 400 mg/kg respectively). A toxicity study has been performed for the extract, which revealed that the extract is safe to use even at the doses of 3.2 gm/kg of body weight orally.
