Canine anti-endotoxin immunotherapy in cranial mesenteric arterial occlusion shock and canine parvovirus disease endotoxaemia.
(1986)Endotoxin (LPS, lipopolysaccharide) forms an integral part of the outer cellular membrane of gram negative bacteria (GNB). The canines' intestine always contains large amounts of GNB, and hence LPS. If these GNB with ... -
Synthesis of DNA - protein conjugates and a preliminary study of their interaction with eukaryotic cell receptors.
(1986)Thymidine oligomers were chemically synthesised and linked to available amino functions of transferrin in alternative orientations: (a) A CMP residue attached to the 3' end of (pT)₁₀ with terminal deoxynucleotidyl transferase ... -
Studies on the preparation and interaction of modified transferrin-DNA complexes with HeLa cells.
(1986)The correction of human genetic disorders by transfer of genetic material to cells is under intensive investigation in a number of 1aboratories. One possible way of trying to achieve the transfer of nucleic acid is ... -
Preparation of chemically modified transferrin proteins and an investigation of their reactions with DNA and other nucleic acids.
(1986)The molecular biology of human genetic disorders is under intensive investigation at present. In those cases where the disorder is clearly defined in terms of altered gene structure, possibilities may exist for the correction ... -
Cloning of the promoter regions of Trypanosoma brucei and Trypanosoma congolense cysteine protease genes.
(1997)Trypanosoma brucei and T. congolense are protozoan parasites that infect humans, domestic livestock and wildlife in Africa. These parasites undergo complex morphological and biochemical changes, during the various stages ... -
Coupling dyes to chicken IgY antibodies for the development of immunodiagnostic tests.
(2003)The aim of this study was to develop a highly simplified, sensitive and specific malarial diagnostic test at the lowest possible cost. Initial work and optimisation of procedures was achieved with chicken antibodies by ... -
Cloning and recombinant expression of a 822 bp region of a Pf403 Plasmodium falciparum gene.
(2003)Malaria is a devastating parasitic disease in humans caused by species in the genus Plasmodium. With over 100 million cases and at least 1.5 million fatalities each year, the disease accounts for 4-5% of all fatalities ... -
Role of neutrophil matrix metalloproteinase-9 (MMP-9) and tissue inhibitor of metalloproteases-1 (TIMP-1) in the killing of microorganisms.
(2003)Microorganisms may evade killing by neutrophils (PMNs) by altering signal transduction and hence phagosome maturation. Secreted, active matrix metalloproteinases (MMPs) appear to be required for PMN killing of pseudomonas ... -
The influence of ionic strength on the kinetics of selected enzymes.
(2005)pH studies are used to gain insight into chemical mechanisms of enzyme catalysed reactions. However, perhaps the most important practical point that is often overlooked in pH studies is control of the ionic strength of ... -
Induction of autoantibodies to cathepsin L as a step towards an anti-cancer vaccine.
(2005)Cancer is a disease that is caused by mutations in somatic cells. Metastasis is the major cause of death from cancer and often complicates treatment. Malignant tumours secrete degradative enzymes such as cathepsin L which ... -
Protease distribution in J774 macrophages
(2007)Cathepsin, matrix metalloproteinase (MMP) enzyme and tissue inhibitor of MMP (TIMP) distribution in J774 mouse macrophages has not been comprehensively studied. The distribution and vesicle regulation, trafficking and ... -
Development of a taxonomy for visual literacy in the molecular life sciences.
(2007)The use of external representations (ERs) such as diagrams and animations in science education, particularly in the Molecular Life Sciences (MLS), has rapidly increased over the past decades. Research shows that ERs have ... -
Characterization of the immunity factor in producer self protection against Leucocin A.
(2008)Lactic acid bacteria produce pediocin-like bacteriocins designated as Class Ha. These antimicrobial peptides are antagonistic against Listeria monocytogenes and other closely related Gram-positive bacteria Self-protection ... -
Evaluation of congopain and Oligopeptidase B as anti-disease vaccines for African Trypanosomiasis.
(2008)The protozoan parasite Trypanosoma congolense is one of the aetiological agents of African animal trypanosomiasis that is transmitted by the tsetse fly. The parasite causes nagana in animals and affects livestock throughout ... -
Endoplasmic reticulum associated degradation (ERAD) overflow pathways.
(2008)Accumulation of misfolded proteins in the endoplasmic reticulum (ER) causes numerous human pathologies. Biochemical evidence suggests that soluble misfolded proteins are retrotranslocated out of the ER, via the endoplasmic ... -
Bioremediation of soil contaminated with a mixture of chlorinated aliphatic hydrocarbons.
(2008)Chlorinated aliphatic hydrocarbons (CAH’s) are a diverse group of industrial chemicals that play a significant role as pollutants of soil and groundwater. They are recalcitrant and resist degradation in most waste treatment ... -
Apoptosis in peripheral blood mononuclear cells of human immunodeficiency virus (HIV) infected patients undergoing highly active antiretroviral therapy.
(2008)Highly active antiretroviral therapy (HAART) is currently the only treatment that effectively reduces the morbidity and mortality of individuals infected with Human Immunodeficiency Virus-1 (HIV-1). Standard HAART regimens ... -
The biochemical effects of Sutherlandia Frutescens in cultured H9 cancerous T cells and normal human T lymphocytes.
(2008)Indigenous plants have long been used by African populations in their cultural lives and health care. Sutherlandia frutescens (SF) is a popular traditional medicinal plant found in various parts of southern Africa and used ... -
Biochemical and microbiological changes in sugarcane stalks during a simulated harvest-to-crush delay.
(2008)Post-harvest cane deterioration in the South African sugar industry results in significant revenue loss that is estimated to be in the region of ZAR 60 million per annum. Despite these large losses, precise biological ... -
Molecular analysis of the congopain gene family.
(2008)Animal trypanosomosis is a major constraint in livestock production in Sub-Saharan Africa. With the emergence of resistance against trypanocidal drugs, the cost and environmental concerns raised by vector control, and the ...
