Die bemagtiging van lewensoriëntering-onderwysers in die Vaaldriehoek, met betrekking tot die MIV-en VIGS-pandemie : die REds-bemagtigingsprogram / Louise Jacoba CoxenCoxen, Louise Jacoba January 2011 (has links)
Teachers are often in contact with children whose family members are affected or infected by the HIV and AIDS pandemic, or children themselves who are affected or infected by the HIV and AIDS pandemic. Often, it is teachers themselves who are suffering due to the HIV and AIDS pandemic.
School training and tertiary training are one of the most important components, which need a lot of attention in a developing country. Teachers play a very important role in developing the youth’s thoughts. School training is often negatively impacted due to absenteeism of teachers, negative attitudes of teachers and the time wasted to replace teachers who are negatively impacted by the HIV and AIDS pandemic or who take medical discharge. Teachers often don’t know how to handle the impact of the HIV and AIDS pandemic and they are also unaware of resources available in this regard.
The REds-programme is a support programme designed for teachers who are affected by the HIV and AIDS pandemic. The aim of the REds-programme is to provide teachers with support so that they will be able to handle the impact of the HIV and AIDS pandemic. The focus is specifically on teachers, as they don’t live or work in isolation. Teachers form part of communities and school units whom are directly impacted by the HIV and AIDS pandemic. The REds-programme was vi
implemented in 2004. This programme is thus running, tested and still in the process of testing, for the past six years.
Article 1 consists of the following:
The nature and content of the REds-programme. The group work process, as well as a discussion of each group work session.
Article 2 consists of the following:
An evaluation of the REds-programme by means of the qualitative and quantitative results obtained.
From the results, it is clear that the REds-programme is a very effective programme from which life orientation teachers can benefit. / Thesis (M.A. (MW))--North-West University, Potchefstroom Campus, 2012

Evaluation of RANTES analogue expression in Nicotiana benthamiana and Lycopersicon esculentum and their topical microbicidal activityMawela, Kedibone Gloria January 2013 (has links)
The HIV/AIDS pandemic has dramatically altered patterns of morbidity and mortality in
sub-Saharan Africa during the last two decades. In the absence of HIV vaccine,
microbicides may offer viable option for protection against HIV infection. Microbicides
are products that are applied topically inside the vagina or rectum that act to impede
transmission of HIV and other sexually transmitted diseases. Small human chemokines
such as RANTES (regulated upon activation, normal T cell expressed and secreted) are
currently been investigated as microbicides candidates.
A number of N-terminally modified RANTES analogues such as 5P12 and 6P4 with a
much higher antiviral potency have been developed and they have strong potential for
use as microbicides. Since plants offer an alternative option for cost effective production
of protein therapeutics, we evaluated the feasibility of expressing 5P12 and 6P4 in
Nicotiana benthamiana species. 5P12 is considered the most promising candidate for
use in the microbicide pipeline because it inhibits HIV infection through cellular receptor
antagonism. Hence its feasibility of expression was also evaluated in Lycopersicon
esculentum (tomato). The two analogues were transiently expressed in the selected
plant species via agrobacterium-mediated transfection.
For expression in N. benthamiana, two different vectors (pTRA and MagnICON) were
used to deliver the two analogues for transient expression. About 6-8 weeks-old N.
benthamiana plants were agroinfiltrated via needle injection and vacuum infiltration
methods and targeted to four subcellular compartments viz: apoplast, chloroplast,
cytosol and endoplasmic reticulum (ER). The agroinfiltrated leaves were replanted,
grown in a tissue culture laboratory and harvested after different periods. For
expression in L. esculentum, the MagnICON constructs were used to deliver the 5P12
gene into four different developmental stages of tomato fruits viz: mature green (MG),
breaker (B), pink (P) and ripe (R) via needle injection. The agroinjected tomato fruits
were incubated in a dark cupboard and harvested after different periods.
xiii
Proteins were extracted from the harvested material and evaluated for 5P12 and 6P4
expression. ELISA results showed expression of 5P12 and 6P4 in N. benthamiana
leaves which was detectable at 3-9 days post infiltration (dpi). Similar results were
obtained for 5P12 and 6P4, consequently only results for 5P12 are reported. The
vacuum infiltrated leaves of both pTRA and MagnICON constructs led to higher yields
than the needle injected leaves. The highest yields were obtained with the MagnICON
constructs. The highest 5P12 expression level of 603 μg/kg fresh weight leaf tissues
(~0.024% TSP) was obtained in the apoplast at 9 dpi. The pTRA constructs had the
highest expression levels of 0.63μg/kg FW in the cytosol at 3 dpi.
5P12 was also detectable at 3-9 dpi in L. esculentum, based on ELISA results. The
highest 5P12 expression of 23.56 μg/kg FW and pH 4.75 tissues was obtained at the
MG stage in the apoplast at 9 dpi. Western blot analysis confirmed the size of plantmade
5P12. Moreover, the plant extracts had anti-viral activity and were not toxic to
TZM-bl cells.
Our results show that the RANTES can be made in both N. benthamiana and L.
esculentum and that the levels are not different from other systems reported previously.
Furthermore, this is the first report that a chemokine has been expressed in plants. The
quantities expressed were low making the commercial development of a microbicide
from these species impractical. However, production of bulky leaf material may enhance
the quantities. / Thesis (PhD)--University of Pretoria, 2013. / gm2013 / Paraclinical Sciences / unrestricted

Die evaluering van die REds–program in die Matlosane–distrik, Noordwes–Provinsie / Reinette JoubertJoubert, Reinette January 2010 (has links)
Because of the HIV– and Aids pandemic, a paradigm shift is currently noticed in the traditional role expectation of educators. Except for didactical education, they are also confronted with professional and personal demands on a daily basis. These changes in professional and personal roles are often traumatic and sufficient coping skills as well as support, seems to be limited. The REds–program (resilient educators) was developed for this reason - to empower educators to cope more resiliently with these demands. This study was conducted in order to determine if this program is effective in the empowerment of educators. Two articles follow, from which the first one examines and explores the content, nature and extent of the program. The evaluation of the REds–program follows in the second article. Findings suggest that there were participants that were empowered in the long run and direct feedback from participants confirm that they found the program to be valuable on professional and personal areas. / Thesis (M.A. (MW.))--North-West University, Potchefstroom Campus, 2011.
