Abstract: Objectives: The purpose was to evaluate the effect of various tooth-whitening products on the South African market, containing carbamide peroxide (CP) or hydrogen peroxide (HP), on enamel microhardness. Methods: Enamel blocks were exposed to: Nite White® ACP 10% CP (group 2, n=10); Yotuel® Patient 10% CP (group 3, n=10); Opalescence® PF 10% CP (group 4, n=10); Opalescence® PF 20% CP (group 5, n=10); Opalescence® Treswhite Supreme 10% HP (group 6, n=10); Yotuel® 10 Minutes 30% CP (group 7, n=10); Opalescence® Quick 45% CP (group 8, n=10), Yotuel® Special 35% HP (group 9, n=10), Opalescence® Boost 38% HP (group 10, n=10) according to the instructions of the manufacturers. The control group (1) was enamel blocks (n=10) kept in artificial saliva at 37˚C without any treatment. The microhardness values were obtained before exposure and after a 14-day treatment period. Specimens were kept in artificial saliva at 37˚C between treatments. Data were analysed using Kruskal-Wallis one-way ANOVA and Tukey-Kramer Multiple Comparison Test. Indent marks on the enamel blocks were also examined under the scanning electron microscope. Results: All whitening products decreased enamel microhardness except group 10. Only Groups 2,3,4,5 and 7 showed significant decrease in enamel microhardness as compared to the control group (p<0.05). Groups 2, 3 and 7 differed significantly from all the other groups (p<0.05). The highest damage was recorded for group 2 (Nite White® ACP 10% CP), which differed significantly from groups 3 and 7. SEM images also showed damage to enamel. Conclusions: All products damaged enamel except Opalescence® Boost 38% HP. In general, the products containing carbamide peroxide were more damaging while longer treatment periods influenced the microhardness values negatively. Nite White® ACP without fluoride showed relatively more damage than all the other products containing fluoride. URI: http://hdl.handle.net/10566/590 Files in this item: 1

Abstract: Introduction: The increase in physical inactivity is thought to be one of the main risk factors for the development of diseases of lifestyle. This has highlighted the need for prevention and intervention programmes that are thought to assist in influencing the modifiable risk factors. Physical activity programmes have been proven to positively influence risk factors such us blood pressure and body mass index (BMI). Interventions by health professionals can assist in combating the problem. This study aimed to determine the effects of a short term physical activity programme on the BMI, body fat and blood pressure of high school learners in a local community in the Western Cape. Methods: The total number of learners who volunteered to participate in the study was 106. The study used a pre-test post-test design. The intervention programme was a 6 week programme run for 3 days per week for a period of 40 – 60 minutes per session. The intervention consisted of moderate to vigorous activities. Data was analysed by comparing learners who participated in the intervention and those who did not. Descriptive and inferential statistics were used in this study. Results: Prior to the intervention it was found that 18% were found to be obese and at least 10% were hypertensive. Following the intervention it was reported that blood pressure as well as BMI and percentage body fat was influenced in positive way. Conclusion: One can conclude that, a short term physical activity intervention programme conducted three times a week with moderate activities can affect the BMI and blood pressure levels of adolescents.

Abstract: This work studies the effect of heat treatment of carbon-dispersed platinum and platinum alloys on its methanol tolerance and catalytic activity as gas diffusion electrodes for oxygen reduction reaction (ORR) in acid medium. The catalyst powders were subjected to heat treatments at three different temperatures for a fixed period at controlled atmospheres. Differences in catalyst morphology were characterized using X-ray diffraction, energy dispersive X-ray analysis and transmission electron microscope techniques. The electrochemical characteristics and activity of the electro-catalysts were evaluated for ORR and methanol tolerance using cyclic voltammetry, in the form of gas diffusion electrodes. The optimum heat-treatment temperature is found to be strongly dependent on the individual catalyst. The maximum ORR activity and better methanol tolerance for the oxygen reduction reaction (ORR) was observed in Pt-Fe/C and Pt-Cu/C catalysts subjected to heat treatment at 350 °C.A trend of catalytic activity for oxygen reduction reaction (ORR) was obtained: Pt-Cu/C (350°C)>Pt-Fe/C (350°C) > Pt-Ni/C (350°C) > Pt-Co/C (250°C) > Pt/C (350°C), showing that Pt-Cu/C-type catalysts had a higher catalytic activity with reasonable methanol tolerance.

Abstract: The use the aqueous decoction of Leonotis leonurus (L. leonurus) (Ll) R. Br. (Lamiaceae) in the treatment of hypertension (HPT) in traditional medicine is well documented. The effect of the aqueous extract of LI on the blood pressure (BP) and heart rate (HR) has been investigated in normotensive rats. The aim of this study was to investigate the effect of Ll aqueous extract on the in isolated perfused rat heart (IPRH). Hearts were excised from male Wistar albino rats weighing 250-350g, aged less than 6 months. They were perfused at constant flow using the modified Langendorff perfused model of the heart. Effects of adrenaline on the left ventricular systolic pressure (LVSP), left ventricular end-diastolic pressure (LVEDP), left ventricular developed pressure (LVDP), heart rate (HR), cardiac work (CW) and coronary perfusion pressure (CPP) were compared to that of Ll. Adrenaline (1µM) significantly (p<0.05) increased the LVSP by 40.6%, the LVDP by 43.9%, the HR by 22.5% and the CW by 89.4%. Ll (1.0 mg/ml and 2.0 mg/ml respectively and significantly (p<0.01) increased the LVSP by 25.36 and 14.91, the LVDP by 29.40 and 14.88. Ll (1.0 mg/ml and 2.0 mg/ml) significantly produced a negative chronotropic effect. Both adrenaline and Ll aqueous extract did not have any significant effect on the LVEDP. Adrenaline resulted in positive inotropic and chronotropic effects. At low concentrations Ll produced a positive inotropic and a negative chronotropic effect. At the concentration of 2.0mg/ml Ll decreased all parameters to zero. At higher concentrations higher than 2.0mg/ml, Ll seemed to have toxic effects on the heart.

Abstract: An efficient and simple method for constructing an environmental library using mechanically sheared DNA obtained directly from geothermal sediments is presented. The method is based on blunt-end modification of DNA fragments followed by 3' -adenylation using Vent DNA polymerase and Taq DNA polymerase, respectively. The prepared DNA fragments are then ligated into a TA cloning vector and used in the transformation of Escherichia coli. This method has been successfully applied to the cloning of ORFs derived from uncultivated prokaryotes present in geothermal sediment. URI: http://hdl.handle.net/10566/161 Files in this item: 1

Abstract: Aeromonas species are ubiquitous bacteria in terrestrial and aquatic milieus. They are becoming renowned as enteric pathogens of serious public health concern as they acquire a number of virulence determinants that are linked with human diseases, such as gastroenteritis, soft-tissue, muscle infections, septicemia, and skin diseases. Proper sanitary procedures are essential in the prevention of the spread of Aeromonas infections. Oral fluid electrolyte substitution is employed in the prevention of dehydration, and broad-spectrum antibiotics are used in severe Aeromonas outbreaks. This review presents an overview of emerging Aeromonas infections and proposes the need for actions necessary for establishing adequate prevention measures against the infections.

Abstract: The Antarctic continent harbors a range of specialized and sometimes highly localized microbial biotopes. These include biotopes associated with desiccated mineral soils, rich ornithogenic soils, glacial and sea ice, ice-covered lakes, translucent rocks, and geothermally heated soils. All are characterized by the imposition of one or more environmental extremes (including low temperature, wide temperature fluctuations, desiccation, hypersalinity, high periodic radiation fluxes, and low nutrient status). As our understanding of the true microbial diversity in these biotopes expands from the application of molecular phylogenetic methods, we come closer to the point where we can make an accurate assessment of the impacts of environmental change, human intervention, and other natural and unnatural impositions. At present, it is possible to make reasonable predictions about the physical effects of local climate change, but only general predictions on possible changes in microbial community structure. The consequences of some direct human impacts, such as physical disruption of microbial soil communities, are obvious if not yet quantitated. Others, such as the dissemination of nonindigenous microorganisms into indigenous microbial communities, are not yet understood. URI: http://hdl.handle.net/10566/145 Files in this item: 1

Abstract: To make sure that service delivery is effective and has a positive impact on people’s quality of life, it is important to have meaningful engagement between communities and the government. South Africa’s Constitution makes provision for individuals and communities to take part in service delivery processes and decisions. This right is important in the fight against poverty, inequality and marginalisation. Some people do not know that their right to participate is protected in the Constitution, in South African legislation and in international law. They also do not know the key principles about meaningful engagement set out by the courts, especially the Constitutional Court. This booklet focuses mainly on the right to housing when it explains the objectives, subject and process of meaningful engagement. URI: http://hdl.handle.net/10566/228 Files in this item: 1

Abstract: The sensitivity of health-care information and its accessibility via the Internet and mobile technology systems is a cause for concern in these modern times. The privacy, integrity and confidentiality of a patient’s data are key factors to be considered in the transmission of medical information for use by authorised health-care personnel. Mobile communication has enabled medical consultancy, treatment, drug administration and the provision of laboratory results to take place outside the hospital. With the implementation of electronic patient records and the Internet and Intranets, medical information sharing amongst relevant health-care providers was made possible. But the vital issue in this method of information sharing is security: the patient’s privacy, as well as the confidentiality and integrity of the health-care information system, should not be compromised. We examine various ways of ensuring the security and privacy of a patient’s electronic medical information in order to ensure the integrity and confidentiality of the information.

Abstract: The regulation of unworthiness to inherit in Book 4 of the (new) Dutch Civil Code (2003) occasioned numerous interpretation and application challenges to Dutch courts, notaries and inheritance scholars. These challenges correspond greatly with many of the contentious issues regarding unworthiness to inherit in modern South African law. This article investigates certain aspects of the Dutch legal position with a view to commenting on, and suggesting solutions to, corresponding challenges in the South African context. Issues such as the effect of unworthiness to inherit on matrimonial property claims as well as maintenance claims against a deceased estate, the suitability and appropriateness for South African law of a “forgiveness provision” that eliminates unworthiness similar to the one included in the Book 4 of the Dutch Civil Code and the regulation of unworthiness to inherit in the context of euthanasia are analysed from a legal-comparative standpoint.

Abstract: In international relations states labelled as ‘middle powers’ are often responsible for crafting a middle way to bridge conflicting international interests. They typically favour multilateralism and cooperative international behaviour. Middle power diplomacy has played a crucial role in the establishment and maintenance of the nuclear non-proliferation regime. South Africa has played the role of a middle power in nuclear diplomacy since 1994, drawing on its moral position after giving up its nuclear weapons. This role has especially involved joining the efforts of middle powers in the North, such as Norway and Canada, to indefinitely extend the Nuclear Non-Proliferation Treaty (NPT). However, South Africa’s foreign policy has shown a gradual shift away from a middle power orientation not least due to an increasing non-aligned position that calls for deep reforms to the perceived unfair world order tilted in the favour of the developed North. This shift is also visible in South African nuclear diplomacy and is eroding the middle ground that has so far sustained the nonproliferation regime. The paper argues that South Africa’s middle power diplomacy has allowed it to punch above its weight in the nuclear realm, but its pursuit of international reforms has resulted in the drawing of a fault line between developed and developing countries. It is in the interest of nuclear non-proliferation to regain the middle ground by forming broad coalitions amongst all actors interested in nuclear disarmament.

Abstract: On the background of the current sense of despair concerning the environmental crisis, this article follows the basic intuition that a Christian environmental praxis can only be empowered on the basis of an adequate understanding of Christian hope. Christian eschatology has traditionally responded to three distinct aspects of the human predicament - human self-enclosure, and finitude in both time and space; instigated by an unacceptable present reality, it articulates the conviction of an upcoming transformation into what it ought to be. Investigating the theme of hope in some major ecclesial documents and literature that explicitly addresses the topic written during the struggle, it is argued that the strength of the eschatology developed during that period consists in its return to the prophetic roots of Christian hope. Its concentration on the anthropological aspect of the liberation from the predicament from human sin makes it necessary to rediscover the impact of eschatology on the salvation of creation and the theocentric aspect of hope.

Abstract: OBJECTIVE: To estimate the burden of disease attributable to excess body weight using the body mass index (BMI), by age and sex, in South Africa in 2000. DESIGN: World Health Organization comparative risk assessment (CRA) methodology was followed. Re-analysis of the 1998 South Africa Demographic and Health Survey data provided mean BMI estimates by age and sex. Population attributable fractions were calculated and applied to revised burden of disease estimates. Monte Carlo simulation-modelling techniques were used for the uncertainty analysis. SETTING: South Africa. SUBJECTS. Adults ≥ 30 years of age. OUTCOME MEASURES. Deaths and disability-adjusted life years (DALYs) from ischaemic heart disease, ischaemic stroke, hypertensive disease, osteoarthritis, type 2 diabetes mellitus, and selected cancers. RESULTS: Overall, 87% of type 2 diabetes, 68% of hypertensive disease, 61% of endometrial cancer, 45% of ischaemic stroke, 38% of ischaemic heart disease, 31% of kidney cancer, 24% of osteoarthritis, 17% of colon cancer, and 13% of postmenopausal breast cancer were attributable to a BMI ≥ 21 kg/m2. Excess body weight is estimated to have caused 36 504 deaths (95% uncertainty interval 31 018 - 38 637) or 7% (95% uncertainty interval 6.0 - 7.4%) of all deaths in 2000, and 462 338 DALYs (95% uncertainty interval 396 512 - 478 847) or 2.9% of all DALYs (95% uncertainty interval 2.4 - 3.0%). The burden in females was approximately double that in males. CONCLUSIONS: This study shows the importance of recognising excess body weight as a major risk to health, particularly among females, highlighting the need to develop, implement and evaluate comprehensive interventions to achieve lasting change in the determinants and impact of excess body weight.

Abstract: There are a number of pressures on researchers in academia and industry to behave unethically or compromise their ethical standards, for instance in order to obtain funding or publish frequently. In this paper a case study of Deaf telephony is used to discuss the pressures to unethical behaviour in terms of withholding information or misleading participants that can result from mono-disciplinary orthodoxies. The Deaf telephony system attempts to automate multiple aspects of relayed communication between Deaf and hearing users. The study is analysed in terms of consequentialist and deontological ethics, as well as multi-loop action learning. Discussion of a number of examples of bad practice is used to indicate both the compatibility of ethical behaviour and good scientific method and that ethical behaviour is a pre-requisite for obtaining meaningful results.

Abstract: This article describes the design and implementation of a module on Advanced Social Work Ethics using a blended learning approach and relying substantially on e-learning as a pedagogical tool. The design is contextualised by elaborating on the parameters in which the module was developed – viz. the minimum standards of the Bachelor of Social Work pertaining to ethics, as well as the e-learning and assessment policies at UWC. The module design and implementation was informed by constructivist pedagogical principles, and made use of the notion of ‘critical friends’ as a means of providing opportunities for students to interact as peers and provide input on each others’ learning, thus decentralising the traditional role of the university lecturer. Examples of assessment tasks devised for the module to illustrate the pedagogical principles are also provided. Students’ responses to their experiences of undertaking the module are drawn from their final journal entries and provide an indication of how the module was operationalised.

Abstract: The absence of a suitable measure to assess the health-related quality of life (HRQoL) of children and adolescents in South Africa, led to the use of the KIDSCREEN-52 questionnaire which was developed and standardised in Europe. The current study is part of a broader study conducted in the Western Cape, which used the KIDSCREEN-52 to explore the influence of exposure to community violence on the subjective HRQoL of a sample of South African adolescents. This study aimed to investigate the reliability and construct validity of the KIDSCREEN-52 in a South African context. The broader study employed stratified interval criterion sampling to select 565 Grade 9 learners, aged 14-18. Participants were selected from six public schools in areas specified by the South African government as comprising key nodal areas in terms of crime in the Western Cape. The dataset for the current study comprised all participants (N=565) of the primary study. As the initial step in validation of the KIDSCREEN-52 in South Africa, the current study examined its factor structure by means of exploratory factor analysis, using principal component analysis with oblimin rotations. It also assessed the internal consistency reliability of each of the scales, using Cronbach’s alpha. Exploratory factor analysis extracted 10 factors as identified by previous studies, with some deviation in the loadings of the last three factors. Items of two scales (“Feelings” and “About Yourself”) divided into three scales, and “Bullying” items were not sufficiently presented in the factor solution. Internal consistency of the measure was shown to be acceptable to good, with Cronbach’s alpha values ranging from 0.76 to 0.81 for the 10 scales.

Abstract: Background: Exclusive breastfeeding (EBF) is reported to be a life-saving intervention in low-income settings. The effect of breastfeeding counselling by peer counsellors was assessed in Africa. Methods:24 communities in Burkina Faso, 24 in Uganda, and 34 in South Africa were assigned in a 1:1 ratio, by use of a computer-generated randomisation sequence, to the control or intervention clusters. In the intervention group, we scheduled one antenatal breastfeeding peer counselling visit and four post-delivery visits by trained peers. The data gathering team were masked to the intervention allocation. The primary outcomes were prevalance of EBF and diarrhoea reported by mothers for infants aged 12 weeks and 24 weeks. Country-specific prevalence ratios were adjusted for cluster effects and sites. Analysis was by intention to treat. This study is registered with ClinicalTrials.gov, number NCT00397150. Findings 2579 mother–infant pairs were assigned to the intervention or control clusters in Burkina Faso (n=392 and n=402, respectively), Uganda (n=396 and n=369, respectively), and South Africa (n=535 and 485, respectively). The EBF prevalences based on 24-h recall at 12 weeks in the intervention and control clusters were 310 (79%) of 392 and 139 (35%) of 402, respectively, in Burkina Faso (prevalence ratio 2·29, 95% CI 1·33–3·92); 323 (82%) of 396 and 161 (44%) of 369, respectively, in Uganda (1·89, 1·70–2·11); and 56 (10%) of 535 and 30 (6%) of 485, respectively, in South Africa (1·72, 1·12–2·63). The EBF prevalences based on 7-day recall in the intervention and control clusters were 300 (77%) and 94 (23%), respectively, in Burkina Faso (3·27, 2·13–5·03); 305 (77%) and 125 (34%), respectively, in Uganda (2·30, 2·00–2·65); and 41 (8%) and 19 (4%), respectively, in South Africa (1·98, 1·30–3·02). At 24 weeks, the prevalences based on 24-h recall were 286 (73%) in the intervention cluster and 88 (22%) in the control cluster in Burkina Faso (3·33, 1·74–6·38); 232 (59%) and 57 (15%), respectively, in Uganda (3·83, 2·97–4·95); and 12 (2%) and two (<1%), respectively, in South Africa (5·70, 1·33–24·26). The prevalences based on 7-day recall were 279 (71%) in the intervention cluster and 38 (9%) in the control cluster in Burkina Faso (7·53, 4·42–12·82); 203 (51%) and 41 (11%), respectively, in Uganda (4·66, 3·35–6·49); and ten (2%) and one (<1%), respectively, in South Africa (9·83, 1·40–69·14). Diarrhoea prevalence at age 12 weeks in the intervention and control clusters was 20 (5%) and 36 (9%), respectively, in Burkina Faso (0·57, 0·27–1·22); 39 (10%) and 32 (9%), respectively, in Uganda (1·13, 0·81–1·59); and 45 (8%) and 33 (7%), respectively, in South Africa (1·16, 0·78–1·75). The prevalence at age 24 weeks in the intervention and control clusters was 26 (7%) and 32 (8%), respectively, in Burkina Faso (0·83, 0·45–1·54); 52 (13%) and 59 (16%), respectively, in Uganda (0·82, 0·58–1·15); and 54 (10%) and 33 (7%), respectively, in South Africa (1·31, 0·89–1·93). Interpretation: Low-intensity individual breastfeeding peer counselling is achievable and, although it does not affect the diarrhoea prevalence, can be used to effectively increase EBF prevalence in many sub-Saharan African settings.
