The nutritive value of Italian ryegrass (Lolium multiflorum) selected for high dry matter and nonstructural carbohydrate contents.
In traditional forage breeding programmes, breeders have spent decades improving the agronomic characteristics of grasses, such as herbage yield, persistence and resistance to diseases, without considering the nutrient ...
The presentation and interpretation of arrow symbolism in biology diagrams at secondary-level.
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 ...
Studies on acid phosphatases of Trypanosoma congolense.
Bloodstream forms of African trypanosomes, which endocytose macromolecules exclusively through their flagellar pockets, contain an acid phosphatase (AcP) activity in this organelle. In the present thesis, AcP activity ...
The development of assays for atractyloside and its localisation in rat tissue.
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 ...
Type IV collagenase and cathepsins L and H : proteinases involved in tumour invasion.
The collagenolytic proteinases, type IV collagenase and cathepsins Land H, have been implicated in tumour invasion and metastasis, by virtue of their degradative action on the extracellular matrix barriers traversed by ...
Using student difficulties to identify and model factors influencing the ability to interpret external representations of IgG-antigen binding.
Scientific external representations (ERs), such as diagrams, images, pictures, graphs and animations are considered to be powerful teaching and learning tools, because they assist learners in constructing mental models ...
Changes in endosome-lysosome pH accompanying pre-malignant transformation.
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.
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 ...
Studies on a multicatalytic, protease complex from Trypanosoma brucei brucei.
Subcellular fractionation (together with immunocytochemical localisation studies) showed that the parasite Trypanosoma brucei brucei possesses a multicatalytic protease complex (MCPTb). This complex is predominantly ...
