Objective: To evaluate the antibacterial efficacy of five Indian medicinal plants such as Acalypha indica L.(A. indica), Aerva lanata(L.) Juss. ex Schult.(A. lanata), Clerodendrum inerme(L.) Gaertn., Pergularia daemia(Forsk.)

The antibacterial efficacy of ethanolic extracts of selected medicinal plants was carried out by disc diffusion method. The potential phytoconstituents of medicinal plant extracts were identified by gas chromatography and mass spectrometry(GC–MS) ***: Among the five medicinal plants tested, A. indica and A. lanata showed the significant antibacterial activity. A. indica showed potential activity against Staphylococcus aureus and E. coli. A. lanata significantly exhibited antibacterial activity against E. coli, Salmonella typhi and Pseudomonas aeruginosa. A total of 19 phytoconstituents were identified in the ethanolic extract of A. indica and A. lanata by GC–MS analysis ***: The results of the present investigation revealed that A. indica and A. lanata, possessed significant antibacterial activity when compared with the other plant extracts tested. The presence of 3-O-methyl-D-glucose by GC–MS analysis in both A. indica and A. lanata extracts has not been reported elsewhere in the literature and the findings in this study could be the first one to report.

Classical Hodgkin＇s Lymphoma Presenting as Acute Hepatic Failure One Case Report

Clinical oncology and cancer researeh 2010年第6期7卷 373-376页

作者： pradipta Guha Shivesh Shanker Sahai Sekhar Mukherjee Sanjoy kumar Chatterjee Department of cardiology G.B. Pant Hospital New Delhi 110002 India. Department of General Medicine Medica College Kolkata-700073 West Bengal India.

A 20-year-old boy presenting daily febrile episodes was suspected to have developed acute hepatic failure. Serologic tests ruled out infectious and autoimmune causes apart from drug toxicity. During clinical examinations, he was found to have generalized enlarged lymph nodes that were then taken biopsy. It was diagnosed as classical Hodgkin＇s lymphoma based on histological examination of the lymph node. A bone marrow biopsy showed marrow infiltration by Hodgkin＇s lymphoma with hemophagocytosis and secondary myelofibrosis. A percutaneous liver biopsy demonstrated hepatic involvement of the same disease. After an extensive work-up, the cause of liver failure was figure out to be only attributed to the involvement of the lymphoma. Hodgkin＇s lymphoma as a cause of hepatic failure is rare and young patients diagnosed as Hodgkin＇s lymphoma causing hepatic failure has been reported very rarely so far.

Color and Texture Segmentation Using an Unified MRF Model

引用

Journal of Computer and Communications 2022年第6期10卷 139-164页

作者： Sucheta Panda pradipta kumar Nanda Department of Computer Application VSSUT Burla India Department of Electronics and Communication Engineering Siksha O Anusandhan Deemed to be University Bhubaneswar India

The color image segmentation problem has two main issues to be solved. The proper choice of a color model and the choice of an appropriate image model are the key issues in color image segmentation. In this work, Ohta (I1, I2, I3) is taken as the color model and different variants of Markov Random Field (MRF) models are proposed. In this regard, a Compound Markov Random Field (COMRF) model is porposed to take care of inter-color-plane and intra-color-plane interactions as well. In continuation to this model, a Constrained Compound Markov Random Field Model (CCOMRF) has been proposed to model the color images. The color image segmentation problem has been formulated in an unsupervised framework. The performance of the above proposed models has been compared with the standard MRF model and some of the state-of-the-art methods, and found to exhibit improved performance.

作者： pradipta kumar Basu Amrita Ghosh Department of Chemistry Hooghly Mohsin College Chinsurah India

A number of doubly-fused [1,2] naphthodifurans have been synthesized from the corresponding diallyl-dihydroxy naphthalene precursors involving N-iodosuccinimide in acetonitrile and also by molecular iodine in aqueous micelle using CTAB as surfactant. The electrophilic cyclization occurs regioselectively by a 5-exo-trig mode of cyclization.

Nodular lymphocyte predominant Hodgkin＇s disease occurs in 5% of all cases of Hodgkin＇s disease. It occurs more commonly in male. Only 5% of all Hodgkin＇s lymphoma cases develop spinal cord compression and in only 0.2% cases, spinal cord compression occurs as the initial presentation. So our case is rare both in the form of the unique variety of Hodgkin＇s disease and also in the form of presentation.

Microstructure, Texture, Mechanical and Ballistic Properties Correlation of a Hot Rolled and Peak Aged AA-7017 Alloy Plate at Surface and Centre

引用

Materials Sciences and Applications 2017年第13期8卷 992-1013页

作者： pradipta kumar Jena Kandikattu Siva kumar Rajiv kumar Mandal Ashok kumar Singh Defence Metallurgical Research Laboratory Hyderabad India Department of Metallurgical Engineering IIT (BHU) Varanasi India

The present work describes microstructure, texture, mechanical and ballistic properties correlation of a hot rolled and peak aged AA-7017 alloy plate at surface and centre. Both the microstructures and textures are different on the surface and centre of the plate. The surface of the plate shows recrystallized grains and a weak over all texture. The centre of the plate displays elongated grains and a sharp texture. Tensile properties, hardness and impact toughness are evaluated at surface and centre of the plate. It is observed that strength and hardness is high at centre, whereas ductility and impact toughness is more at the surface. Ballistic properties of the plate at centre and surface are measured by impacting against two different 7.62 mm deformable projectiles. The plates impacted on the surface shows better ballistic resistance. Ballistic performance of the plate at surface and centre has been correlated with the microstructure, texture and mechanical properties.
