The presentation and interpretation of arrow symbolism in biology diagrams at secondary-level.
(2006)
The literature contains conflicting ideas about the effectiveness of diagrams, and their constituent
symbolism as teaching and learning tools. In addition, only limited research has been specifically
conducted on the ...
The development of assays for atractyloside and its localisation in rat tissue.
(1991)
An extract of the tuber of Callilepis laureola is regarded as the source of a powerful
therapeutic agent, known as Impila. Its use is associated with fatal hepatic and renal
necrosis, the renal toxin being atractyloside ...
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 ...
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 ...
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 ...
Changes in endosome-lysosome pH accompanying pre-malignant transformation.
(2005)
The mechanisms by which altered processing, distribution and secretion of proteolytic
enzymes occur, facilitating degradation of the extracellular matrix in invasive and
metastatic cells, are not fully understood. Studies ...
Quantitative imaging of tyrosine kinase-drug interactions in cells.
(2012)
Kinases play a crucial role in regulating cellular signaling cascades, making them
therapeutic targets for several human diseases. In human cancers, mis-regulation and
mutations of kinases such as EGFR (epidermal growth ...
Apoptosis, redox stress and cancer.
(2000)
Apoptosis is a regulated "programme" by which cells are induced to die in a
manner which does not result in pathological inflammatory reactions, and involves dismantling of the cell into membrane-bound fragments that are ...
Nickel accumulation and tolerance in Berkheya coddii and its application in phytoremediation.
(1998)
As pollution becomes an ever-increasing threat to the global environment pressure is being
placed upon industry to "clean-up" its act, both in terms of reducing the possibility of new
pollution and cleaning up already ...
VP4 : a putative protease encoded by infectious bursal disease virus.
(2000)
Infectious bursal disease virus (IBDV) causes an acute and highly contagious disease
affecting young chickens, which is responsible for significant losses in the poultry industry
world-wide. The virus specifically infects ...
