Research ArticleOpen accessIn the abstractPOST KALA-AZAR DERMAL LEISHMANIASIS WITH ULCERATION ON FOOT: AN ATYPICAL CASE PRESENTATION SUCCESSFULLY TREATED WITH MILTEFOSINEVidyanand Rabi Das, Dharmendra Singh, Krishna Murti et al.Visceral Leishmaniasis (VL) or Kala-Azar (KA) is highly endemic in the Indian subcontinent particularly in Bihar. Post Kala-azar Dermal Leishmaniasis (PKDL) is a known reservoir for leishmania parasites for transmission of VL. The kala-azar elimination program was launched by the government of three countries of the Indian subcontinent in the year 2005, which aims to eliminate kala-azar by 2015 and … …American Journal of Infectious Diseases, Vol. 10, Issue 2 · 2 Apr 2014 · 7,586 accessesView PDFCite
Research ArticleOpen accessIn the abstractStimulatory Effects of Dihydroartemisinin on the Leucocyte Population of Wistar Albino RatsU. A. Utoh-Nedosa, P. A. Akah, C. O. Okoli et al.Problem statement: Five dosages of Dihydroartemisinin (DHA) which included 1 mg kg-1; a repeated dose of 1; 2; 60 and 80 mg kg-1 were administered orally to albino rats for 5 days. The results of the study showed that dihydroartemisinin treatment significantly elevated the total white cell count (p<0.01); the percentage neutrophil count (p<0.01) and the percentage lymphocyte count (p<0.05). … …American Journal of Infectious Diseases, Vol. 7, Issue 3 · 17 Nov 2011 · 7,353 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of the Activity of Plant Extracts in Boer GoatsM. Worku, R. Franco, J. H. MillerProblem statement: The effect of extracts from Neem (Azadirachta indica), Wormwood (Artemisia absinthium) and Tobacco (Nicotiana tabacum) with added copper sulfate, on female Boer goats infected with gastrointestinal parasites (GIN) was evaluated. Approach: Following initial screening for infection, animals were artificially infected with a mix containing approximately 80% Haemonchus contortus and 20% Trichostrongylus spp. After 21 days, fecal samples were … …American Journal of Animal and Veterinary Sciences, Vol. 4, Issue 4 · 21 Dec 2009 · 8,477 accessesView PDFCite
Research ArticleOpen accessIn the abstractStatistical Analysis of the Risk Factors of the Major Epidemic Disease Among Residents of Sekondi-Takoradi Metropolis (STMA)A. J. Turkson, X. J. WangProblem statement: This study focused on statistical analysis of risk factors of the major disease among residents of STMA. The objectives of the study were to find the predominant diseases affecting residents in the catchments area. The study was also meant to identify risk factors associated with the incidence of the predominant disease. Approach: Purposive sampling technique was used to … …Journal of Mathematics and Statistics, Vol. 5, Issue 3 · 30 Sep 2009 · 7,526 accessesView PDFCite
Research ArticleOpen accessIn the abstractImmunomodulatory and In vivo Antiplasmodial Activities of Propolis ExtractsSyamsudin, Rita Marleta Dewi, KusmardiProblem statement: Malaria caused by various species of prozoan parasites, Plasmodium. The exact mechanism of humoral immunity in eliminating Plasmodium is not completely understood. However, an antimalarial antibody is strongly suspected to play important role in immunity. The purpose of this research was to evaluate the immunomodulator and antiplasmodial activities of Indonesian propolis extracts. Approach: Thirty male BALB/c mice weighing … …American Journal of Pharmacology and Toxicology, Vol. 4, Issue 3 · 30 Sep 2009 · 7,802 accessesView PDFCite
Research ArticleOpen accessIn the abstractCreation of Tetracycline Regulatable Knockouts of ORFF Gene from the LD1 Locus of Leishmania donovaniBindu Sukumaran, Manju Jain, Peter J. Myler et al.The tetracycline repressor/operator system was adapted for use in Leishmania donovani. In order to investigate the possible importance and function of open reading frame F (ORFF) in Leishmania donovani strain AG83 that has a single copy of ORFF in the LD1 locus on chromosome 35, we have attempted to generate tetracycline regulatable single allele mutants of ORFF. Leishmania cells expressing … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 4 · 31 Dec 2007 · 6,832 accessesView PDFCite
Research ArticleOpen accessIn the abstractFunctional Characterization of Neutrophils from Nine-Banded Armadillos (Dasypus novemcicntus; Edentata, Dasypodidae) Infected with MicrofilariaeMarcela López-Hurtado, Fernando M. Guerra-InfanteThe neutrophils from uninfected armadillos have adequate phagocytic and bacteriocidal activity, but diminished chemotactic activity. However, endocytic activity from armadillo neutrophils infected with bacteria, parasites or viruses is unknown. This report shows that neutrophils from armadillos infected with microfilariae displayed deficiencies in their bacteriocidal mechanisms and TNF-like production, but not in their endocytic capacity. …American Journal of Animal and Veterinary Sciences, Vol. 1, Issue 1 · 30 Jun 2006 · 6,662 accessesView PDFCite
Research ArticleOpen accessIn the abstractTowards 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 · 6,759 accessesView PDFCite
