Production of tomatoes is profitable by considering cost and benefit. … …American Journal of Economics and Business Administration, Vol. 14, Issue 1 · 23 May 2022 · 6,751 accessesView PDF Cite

Research ArticleOpen accessIn the author namesCD2 Shown to Facilitate CD4+ Cell Differentiation during Visceral Leishmaniasis, a Receptor Based StudySukrat Sinha, Shanthy Sundaram, Sanjiva Bimal et al.This study addressed the role of CD2 on CD4+ T helper cells in relation to the TCRVα1 and CD70 in two groups of BALB/c mice viz control and infected (1×107 L. donovani promastigotes). The results showed with the downregulation of CD2 expression there is a pronounced decrease of TCRVα1 and CD70 on CD4+ cells in mice. An insight into the … …American Journal of Biochemistry and Biotechnology, Vol. 11, Issue 4 · 28 Nov 2015 · 7,828 accessesView PDF Cite

Research ArticleOpen accessIn the author namesLeishmania donovani: Immunomodulatory Role of 63KDa Leishmania Antigen in the Promotion of IFN-gamma Response (VL vs HIV-VL Co-infection)Pranati, Sanjiva Bimal, K. Pandey et al.Cytokine behavior of T-lymphocytes is not very clear when a patient is co-infected with Leishmania donovani and HIV. To achieve this we studied groups of patients comprising of VL infected, HIV infected and HIV-VL co-infected cases. As compared to lone infections by either of the infecting agent, the co-infection cases showed greatly diminished CD4 T-cell counts and slightly enhanced values … …American Journal of Immunology, Vol. 2, Issue 2 · 30 Jun 2006 · 7,000 accessesView PDF Cite

Research ArticleOpen accessIn the author namesTowards Identifying Immunogenic Targets in Visceral Leishmaniasis: Role of 17kDa and 63kDa PhosphoproteinsShubhankar K Singh, Sanjiva Bimal, Diwakar S. Dinesh et al.We observed predominant phosphorylation at Protein Kinase C (PKC-α) residue in seven immunoreactive proteins of virulent Leishmania donovani parasites. These phosphoproteins were tested for their ability to stimulate T-cells for secretion of Macrophage Migration Inhibition Factor (MIF) in comparision to crude soluble antigen in Visceral Leishmaniasis (VL) patients. Two of these phosphorylated L. donovani antigens led Leishmania to present these … …American Journal of Immunology, Vol. 1, Issue 3 · 30 Sep 2005 · 6,756 accessesView PDF Cite

Research ArticleOpen accessIn the author namesComparative Evaluation of Aqueous and Freeze Dried Antigen for Sero-diagnosis of VL and PKDL Cases by DATSanjiva Bimal, Shubhankar K. Singh, P. K. Sinha et al.The efficacy of aqueous and freeze dried (FD) antigen was evaluated by direct agglutination test (DAT) for sero-diagnosis of visceral leishmaniasis. A total of 16 samples collected from 5 confirmed Kala-azar (KA) cases, 6 cases 2 each of filariasis, malaria, leprosy and 5 non-endemic healthy subjects were used in determination of cut off titre of both the antigens in DAT. … …American Journal of Immunology, Vol. 1, Issue 2 · 30 Jun 2005 · 6,834 accessesView PDF Cite
