Sequence analysis of a Cowdria ruminantium lamdba (sic) GEM-11 clone
(Stellenbosch : Stellenbosch University, 2002-12)
ENGLISH ABSTRACT: Heartwater is a major threat to livestock in Africa due to its high mortality rate. The
intracellular nature of the causative organism, Cowdria ruminantium, makes it difficult to
study, hence an effective ...
Sucrose accumulation and the expression of neutral invertase in sugarcane
(Stellenbosch : Stellenbosch University, 2001-12)
ENGLISH ABSTRACT: The goals of this project were to (i) determine maximum extractable neutral invertase (NI)
activity in the sugarcane culm, (ii) sequence a cDNA encoding for the sugarcane NI (SNI),
(iii) determine SNI ...
An investigation of the interactions of the androgen receptor with a non-steroidal compound and two synthetic progestins
(Stellenbosch : Stellenbosch University, 2002-12)
ENGLISH ABSTRACT: The aim of this thesis was to define the interactions of the androgen receptor
(AR) with an analog of a non-steroidal plant compound, Compound A (CpdA), as
well as two synthetic progestins, medroxyprogesterone ...
UF membranes operated on paper machine wastewater : fouling tendencies and characterisation
(Stellenbosch : Stellenbosch University, 2001-12)
ENGLISH ABSTRACT: At the Mondi Kraft paper mill in Piet Retief, paper machine effluent is pre-treated by means
of dissolved air flotation (DAF) and a mierostrainer prior to ultrafiltration (UF). Despite the
rigorous ...
Functional analysis and recombinant expression of a sea urchin G-string binding factor
(Stellenbosch : Stellenbosch University, 2001-12)
ENGLISH ABSTRACT: The sea urchin G-string binding factor 1 (suGF1) has previously been shown to bind with
high affinity and selectivity to stretches of contiguous deoxyguanosine residues, a DNA
motif found in the upstream ...
Computational systems biology of sucrose accumulation in sugarcane
(Stellenbosch : University of Stellenbosch, 2006-03)
This thesis is about mathematical modelling of sucrose accumulation in the storage perenchyma of Saccharum officinarum (sugarcane) In 2001, Rohwer & Botha (76) published a kinetic model that described the defining feature ...
An investigation of the role of phosphorylation at Ser211 of the glucocorticoid receptor in ligand-specific transcriptional regulation
(Stellenbosch : University of Stellenbosch, 2005-12)
Endogenous glucocorticoids (GCs) modulate many physiological functions in the human
body and synthetic GCs are the most effective therapy in the treatment of inflammation,
autoimmune and endocrine disorders. However, the ...
Control analysis of adrenal Sseroidogenesis

This study describes:
1. Investigation of product inhibition regarding the metabolism of progesterone in ovine
adrenal micosomes.
2. The employment of novel cell culture techniques to study the effect of CYP17 and ...
The development of enzyme-linked immunosorbent assays to detect potato virus Y and potato leaf roll virus using recombinant viral coat proteins as antigens
(Stellenbosch : University of Stellenbosch, 2005-04)
ENGLISH ABSTRACT: Potato Virus Y (PVY) and Potato Leafroll Virus (PLRV) are two of the most destructive
potato viruses capable of drastically diminishing crop yields by up to 80%. The presence of
these viruses in planting ...
Preliminary investigations into ostrich mycoplasmas : identification of vaccine candidate genes and immunity elicited by poultry mycoplasma vaccines
(Stellenbosch : Stellenbosch University, 2006-12)
ENGLISH ABSTRACT: Ostrich farming is of significant economical importance in South Africa. Three ostrich mycoplasmas,
Ms01, Ms02 and Ms03 have been identified previously, and were provisionally named ‘Mycoplasma
struthiolus’ ...
