MEDICAL technology , *NEW product development - Abstract
Despite recent gains, South Africa is yet to fully develop its economic potential in the medical technologies industry. Yet it remains uncertain which parts of the extended medical technologies industry South Africa should prioritise. This paper uses the input-output product space (IO-PS) methodology to identify key areas in the medical technologies industry that are likely to unlock the industry’s potential in South Africa. The analysis involved using a hierarchical mapping of the industry as input to the IO-PS analysis. Thereafter, the outputs of the methodology were analysed and interpreted. The most promising products for further development under various scenarios were identified. [ABSTRACT FROM AUTHOR]

Mariam Arain, Maliha Haque, Lina Johal, Puja Mathur, Wynand Nel, Afsha Rais, Ranbir Sandhu, Sushil Sharma Saint James School of Medicine, Kralendijk, Bonaire, The Netherlands Abstract: Adolescence is the developmental epoch during which children become adults – intellectually, physically, hormonally, and socially. Adolescence is a tumultuous time, full of changes and transformations. The pubertal transition to adulthood involves both gonadal and behavioral maturation. Magnetic resonance imaging studies have discovered that myelinogenesis, required for proper insulation and efficient neurocybernetics, continues from childhood and the brain's region-specific neurocircuitry remains structurally and functionally vulnerable to impulsive sex, food, and sleep habits. The maturation of the adolescent brain is also influenced by heredity, environment, and sex hormones (estrogen, progesterone, and testosterone), which play a crucial role in myelination. Furthermore, glutamatergic neurotransmission predominates, whereas gamma-aminobutyric acid neurotransmission remains under construction, and this might be responsible for immature and impulsive behavior and neurobehavioral excitement during adolescent life. The adolescent population is highly vulnerable to driving under the influence of alcohol and social maladjustments due to an immature limbic system and prefrontal cortex. Synaptic plasticity and the release of neurotransmitters may also be influenced by environmental neurotoxins and drugs of abuse including cigarettes, caffeine, and alcohol during adolescence. Adolescents may become involved with offensive crimes, irresponsible behavior, unprotected sex, juvenile courts, or even prison. According to a report by the Centers for Disease Control and Prevention, the major cause of death among the teenage population is due to injury and violence related to sex and substance abuse. Prenatal neglect, cigarette smoking, and alcohol consumption may also significantly impact maturation of the adolescent brain. Pharmacological interventions to regulate adolescent behavior have been attempted with limited success. Since several factors, including age, sex, disease, nutritional status, and substance abuse have a significant impact on the maturation of the adolescent brain, we have highlighted the influence of these clinically significant and socially important aspects in this report.

Sushil Sharma,1 Afsha Rais,1 Ranbir Sandhu,1 Wynand Nel,1 Manuchair Ebadi21Saint James School of Medicine, Bonaire, The Netherlands; 2Department of Pharmacology, Physiology, and Therapeutics, Center of Excellence in Neuroscience, University of North Dakota School of Medicine and Health Sciences, Grand Forks, ND, USAAbstract: Mammalian metallothioneins (MTs) are low molecular weight (6–7 kDa) cysteine-rich proteins that are specifically induced by metal nanoparticles (NPs). MT induction in cell therapy may provide better protection by serving as antioxidant, anti-inflammatory, antiapoptotic agents, and by augmenting zinc-mediated transcriptional regulation of genes involved in cell proliferation and differentiation. Liposome-encapsulated MT-1 promoter has been used extensively to induce growth hormone or other genes in culture and gene-manipulated animals. MTs are induced as a defensive mechanism in chronic inflammatory conditions including neurodegenerative diseases, cardiovascular diseases, cancer, and infections, hence can serve as early and sensitive biomarkers of environmental safety and effectiveness of newly developed NPs for clinical applications. Microarray analysis has indicated that MTs are significantly induced in drug resistant cancers and during radiation treatment. Nutritional stress and environmental toxins (eg, kainic acid and domoic acid) induce MTs and aggregation of multilamellar electron-dense membrane stacks (Charnoly body) due to mitochondrial degeneration. MTs enhance mitochondrial bioenergetics of reduced nicotinamide adenine dinucleotide–ubiquinone oxidoreductase (complex-1), a rate-limiting enzyme complex involved in the oxidative phosphorylation. Monoamine oxidase-B inhibitors (eg, selegiline) inhibit α-synuclein nitration, implicated in Lewy body formation, and inhibit 1-methyl 4-phenylpyridinium and 3-morpholinosydnonimine-induced apoptosis in cultured human dopaminergic neurons and mesencephalic fetal stem cells. MTs as free radical scavengers inhibit Charnoly body formation and neurodegenerative α-synucleinopathies, hence Charnoly body formation and α-synuclein index may be used as early and sensitive biomarkers to assess NP effectiveness and toxicity to discover better drug delivery and surgical interventions. Furthermore, pharmacological interventions augmenting MTs may facilitate the theranostic potential of NP-labeled cells and other therapeutic agents. These unique characteristics of MTs might be helpful in the synthesis, characterization, and functionalization of emerging NPs for theranostic applications. This report highlights the clinical significance of MTs and their versatility as early, sensitive biomarkers in cell-based therapy and nanomedicine.Keywords: metallothioneins, free radicals, Charnoly body, α-synuclein index, nanomedicine, toxicity, stem cells, theranostics

Notes ��� Fusarium chuoi resides in the Asian clade of the Fusarium fujikuroi species complex (FFSC: O���Donnell et al. 1998, Yilmaz et al. 2021, Crous et al. 2021b). Based on nucleotide searches using the Fusarium Pairwise ID engine on the Fusarioid-ID database (www.fusarium.org, Crous et al. 2021) the closest hit using the ITS sequence was Fusarium siculi (strain CBS 142422; identities = 449/450 (99 %), no gaps). The closest hit using the LSU sequence was F. siculi (strain CBS 142422; identities = 804/805 (99 %), no gaps). Closest hit using the cmdA sequence was Fusarium fractiflexum (strain NRRL 28852; identities = 426/434 (98 %), no gaps). Closest hit using the rpb1 sequence was F. fujikuroi (strain NRRL 13566; identities = 687/702 (98 %), no gaps). Closest hit using the rpb2 sequence was Fusarium globosum (strain CBS 428.97; identities = 856/867 (98 %), no gaps). Closest hit using the tef1 sequence was F. fractiflexum (strain NRRL 28852; identities = 619/643 (96 %), 2 gaps (0.3 %)). The phylogenetic results, however, showed that F. chuoi is not directly related to any of the previously described species of FFSC (see Suppl. material FP1353), clustering as the second basal-most species of that clade after F. sacchari. Asian Fusarium spp. in the FFSC are characterised by mono-and polyphialides producing oval to ellipsoid, rarely pyriform to globose (i.e., F. annulatum, F. fujikuroi and F. globosum) microconidia organized in chains or false heads; 3���5-septate sporodochial conidia and lacking chlamydospores. The elaborate, profusely branched aerial conidiophores of F. chuoi are comparable to those of F. concentricum, F. lumajangense, F. mangiferae and F. sacchari, all the latter species producing oval, ellipsoidal to allantoid microconidia on false heads.Aerial conidiophores of F. chuoi, however, mostly produce macroconidia, while microconidia grouped on false heads are restricted to short, mostly unbranched and prostrate conidiophores formed on the surface on the culture media. Several Asian species of the FFSC have been reported from Musa spp. i.e., F. annulatum, F. concentricum, F. fujikuroi, F. lumajangense and F. sacchari (Leslie & Summerell 2006, Maryani et al. 2019, Farr & Rossman 2021). The two strains representing F. chuoi were isolated as endophytes from asymptomatic seeds of wild banana (Musa itinerans), which had been collected predispersal and stored in the Millennium Seed Bank for ~2.5 years at -20 �� C prior to isolation.

OBJECTIVES: Previous studies suggest a strong relationship between obesity and hypertension. This study aimed at evaluating the prevalence of hypertension and pre-hypertension in 10- to 14-year-old boys and girls in the Eastern Cape Province of South Africa and to determine the association between blood pressure parameters and selected measures of adiposity. METHODS: A cross-sectional, school-based study of 540 10- to14-year-old children from seven schools in the Eastern Cape Province was carried out. Anthropometry and blood pressure parameters were determined. RESULTS: All measures of adiposity and blood pressure were significantly higher in the girls (p < 0.05). The prevalence of hypertension and pre-hypertension was over 20 and 12%, respectively. Systolic blood pressure and pulse pressure were associated (r > 0.27; p < 0.05) with increasing levels of adiposity. CONCLUSION: This study highlights the importance of weightcontrol strategies for the prevention of hypertension in these adolescents and later on in life.

18. Theories of change steering transformation at the UFS: a conceptual analysis

- Abstract
The historically white universities, particularly the Afrikaans-speaking in South Africa were seen to be determined not to transform. However, at the dawn of democracy, there seem to be eagerness to change. This was prompted by the National Education Policy Investigation (NEPI, 1992) and the National Commission of Higher Education (NCHE, 1996) that resulted in the increased participation of black students who were previously excluded from the historically white campuses. Due to the increase of black students a great number of challenges emerged, e.g. the revision of the curricula, teaching approaches and the universities’ autonomy. As a historically white university, the UFS had to follow the new democratic government instruction of transformation which was accelerated at beginning of the 20’s. In order to trace the transformation initiatives at the UFS, a number of relevant documents was consulted, e.g. 1) Education policy documents on higher education, i.e. The Constitution of the RSA, NEPI-1992, NCHE-1997, Education White Paper 3-1997, National Plan For Higher Education-2001, Guidelines for Mergers and Incorporations-2003, the UFS Ministerial Reports on Transformation and Social Cohesion and the Elimination of Discrimination in Public Higher Education Institutions (2008), The Oversight Committee on university transformation-2013 and Higher Education South Africa (HESA) presentations to the Portfolio Committee on Higher Education-2014. 2) Research articles advocating change in South African Education sector, 3) Academic and research articles advocating transformation at the UFS and 4) the Annual Reports of the UFS to the Minister of Higher Education & Training. Meta-Analysis was performed on both the results of the survey that aimed at determining the perceptions and experiences of students and staff regarding race and ethnic issues at the UFS in 2010 (Louw, Jooste and Makae, 2011) and the results from the Perception Audit commissioned by the UFS in February 2014

- Abstract
The aim of this study was to formulate a framework for consolidating support for learners who display inappropriate behaviour, in order to enhance learner attainment. Participants in this study acted as co-researchers according to the PALAR methodology. This study used a seven-chapter approach to investigating the possibility of providing learners with consolidated support, which required a joint effort by the relevant stakeholders to a) validate the need for formulating the envisaged framework; b) identify the main components necessary for the implementation of the framework; c) anticipate possible threats that may impede the successful implementation of the framework; d) explore the conditions conducive to the sustainability of the framework; and e) to monitor the application of the framework. Seemingly, the abolishment of corporal punishment and the promulgation of legislation that safeguards the well-being of children have led to an escalation of inappropriate behaviour by learners. So, through Ubuntu, as the foundation on which the framework was based, integrated support, which was driven by participatory action learning and action research, was proposed, to ensure that we all take responsibility and accept the challenge of building a humane and caring society by responding to the research question. I used literature to develop constructs that act as organising principles that guide the study to achieve its objectives. Data generated were analysed through the use of critical discourse analysis as advocated by Van Dijk. It was because of the tenets of Ubuntu that the study proposed strong collaboration, based on sound relationships, between stakeholders. Learners displaying inappropriate behaviour were provided with constructive behavioural support programmes, which were within the confines of pieces of legislation, to positively reinforce the exhibition of appropriate behaviour. Therefore, a framework that emphasises collaborative, multi-sectoral support to fac

A qualitative research approach was followed and entailed official document analysis and in-depth interviews. Sixteen key informants were selected and interviewed. The data was thematically analysed so that patterns could be identified. The key findings of this study were: The IRSJ is a strategic unit in the process of pursuing institutional transformation within the UFS. Facilitating the transformation process at UFS equals a higher cognitive legitimate institution because its organisational activities become more in line with the recommendations of the higher education sector as well as the wider social system. Transformation represents a novel idea that needs to be introduced within UFS’ institutional walls. This is not an easy task, but the IRSJ is doing a progressive and productive job by using strategic reframing strategies such as the critical conversations. The IRSJ completes a challenging task of strategically reframing the novel idea of transformation in order to gather more support for this greater goal. They do this by helping people better understand the importance of transformation. This topic is so sensitive and challenging to comprehend that a safe space such as the IRSJ is vital in achieving a transformed institution. Once the UFS will have achieved its transformation goals, it will become a more cognitive legitimate institution that is more accepted by the wider social system.

- Abstract
A robust understanding of Antarctic Ice Sheet deglacial history since the Last Glacial Maximum is important in order to constrain ice sheet and glacial-isostatic adjustment models, and to explore the forcing mechanisms responsible for ice sheet retreat. Such understanding can be derived from a broad range of geological and glaciological datasets and recent decades have seen an upsurge in such data gathering around the continent and Sub-Antarctic islands. Here, we report a new synthesis of those datasets, based on an accompanying series of reviews of the geological data, organised by sector. We present a series of timeslice maps for 20 ka, 15 ka, 10 ka and 5 ka, including grounding line position and ice sheet thickness changes, along with a clear assessment of levels of confidence. The reconstruction shows that the Antarctic Ice sheet did not everywhere reach the continental shelf edge at its maximum, that initial retreat was asynchronous, and that the spatial pattern of deglaciation was highly variable, particularly on the inner shelf. The deglacial reconstruction is consistent with a moderate overall excess ice volume and with a relatively small Antarctic contribution to meltwater pulse la. We discuss key areas of uncertainty both around the continent and by time interval, and we highlight potential priorities for future work. The synthesis is intended to be a resource for the modelling and glacial geological community.

- Abstract
This study was undertaken in order to develop a model of facilitation of emotional intel- ligence to promote wholeness in neophyte critical care nurses in South Africa. A theory- generative, explorative, descriptive, contextual research design was used. The model was developed utilising the four steps of theory generation as proposed by Dickoff, James, and Wiedenbach (1968), Chinn and Kramer (2011) and Walker and Avant (2011). Step one dealt with the empirical phase in which the concepts were distilled. The facilitation of inherent affective and mental resourcefulness and resilience was the main concept of the model. Step two comprised the definition and classification of central and related concepts. Step three provides a description of the model. The model operates in three phases namely the dependent phase, partially dependent phase and the independent phase. Step four entailed the description of guidelines for operationalizing the model. During the three phases of the model a new nurse who starts to work in critical care moves from a latent ability to develop an inherent affective and mental resourcefulness and resilience to a state of developing an inherent affective and mental resourcefulness and resilience. This model provides a structured framework for the facilitation of emotional intelligence (EI) to pro- mote wholeness in nurses who commence to work in critical care units.

The plant pathogenic asexual fungus
Thielaviopsis basicola (Ascomycota) causes black root rot on many important agricultural and ornamental plant species. Since its first description in 1850, this species has had a tumultuous taxonomic history, being classified in many different genera. Thus far, DNA‐based techniques have not played a significant role in identification ofT. basicola and have been used only to confirm its placement in the Microascales. This investigation reconsidered the phylogenetic placement ofT. basicola , using DNA sequence data for six different gene regions. It included 41 isolates identified asT. basicola from 13 geographical locations worldwide. Phylogenetic analyses showed that these isolates grouped in a well‐supported lineage distinct from other genera in the Ceratocystidaceae, here described asBerkeleyomyces gen. nov. The data also provided robust evidence that isolates ofT. basicola include a cryptic sister species. As a result, this report provides a new combination asB. basicola comb. nov. and introduces a new species asB. rouxiae sp. nov. [ABSTRACT FROM AUTHOR]- Published

- Abstract
The polyphagous shot hole borer (PSHB), an ambrosia beetle (Coleoptera: Curculeonidae: Scolytinae) native to Asia, together with its fungal symbiont
Fusarium euwallaceae, has emerged as an important invasive pest killing avocado and other trees in Israel and the United States. The PSHB is one of three cryptic species in theEuwallacea fornicatus species complex, the taxonomy of which remains to be resolved. The surge in the global spread of invasive forest pests such as the PSHB has led to the development of programmes utilising sentinel tree plantings to record new host-pest interactions. During routine surveys of tree health in botanical gardens of South Africa undertaken as part of a sentinel project, an ambrosia beetle/fungal associate was detected damagingPlatanus xacerifolia (London Plane) in the KwaZulu-Natal National Botanical Gardens, Pietermaritzburg. Identification of the beetle by sequencing part of the mitochondrial cytochrome oxidasec subunit 1 (COI) gene confirmed its identity as PSHB, and specifically one of the invasive haplotypes of the beetle. The associated fungusF. euwallaceae was identified based on phylogenetic analysis of elongation factor (EF 1-α ) sequences. Koch’s postulates have confirmed the pathogenicity of fungal isolates toP. xacerifolia . This is the first report of PSHB and its fungal symbiont causing Fusarium dieback in South Africa. This report also represents the first verified case of a damaging invasive forest pest detected in a sentinel planting project, highlighting the importance of such studies. Given the potential impact these species present to urban trees, native biodiversity and agriculture, both the PSHB and its fungal symbiont should be included in invasive species regulations in South Africa.

Black staff, historically White Afrikaans university, race, social justice, reconciliation, critical discourse approach, transformative resistance - Abstract
In an ethnographically designed study, guided by a critical community psychology framework, Black staff members at a historically White Afrikaans university campus conducted email conversations relating to issues of race, social justice and reconciliation. The conversations were initiated by the author (Black) who mainly used prompts found in the local institutional context to elicit responses from colleagues. A critical discourse approach to thematic analysis of the email conversations was followed. The main findings are: Compared to the potential number of respondents (32 Black staff members or 18% of all faculty staff), very few colleagues (9 or 28% of Black staff members) responded via email to the invitations but, when met in person, all expressed strong views on the topics or prompts used in the initialising emails. The critical discourse approach revealed clear psychopolitical awareness and strong discourses of fear, powerlessness and bitterness, as well as a discourse of non-engagement. These discourses appeared in all three domains of analysis: local, institutional and societal. Theoretical explication is sought mainly in resistance theory for the discourse of non-engagement and the scarcity of responses located in the local domain. Transformative resistance is suggested so that alternative discourses are inculcated, at least, in faculties of education at some historically White Afrikaans university campuses.

- Abstract
Rainfall measured on the KwaZulu-Natal Drakensberg escarpment, the first from above 2 800m a.s.l., are presented from two locations. Total rainfall at the top of Sani Pass (2 850 m a.s.l.) in the southern Drakensberg was 742 mm in 2002, while the January months of 2002 and 2003 averaged 109 mm. Rainfall on Sentinel Peak (3 165 m a.s.l.) in the northern KZN Drakensberg during 2003 totalled 765 mm and 145 mm was measured in January 2003. Recorded rainfall was marginally lower than, but within 6% of, rainfall recorded at adjacent lower altitude Drakensberg stations over the same period. The number of rain days increased marginally with altitude and the data suggest that even though the amount of rainfall on the escarpment is similar to that at lower altitude, the frequency of rainfall events is higher on the escarpment. Although 2002 and 2003 were dryer than normal years in the region, comparisons between these data and prior estimations, where rainfall was expected to range between 1 500 and 2 000 mm/a, shows that totals for the summit of the escarpment could have been over-estimated in the past. Measurement of rainfall is ongoing. Water SA Vol.31 (3) 2005: pp.399-402

VALUE chains ,FINANCE literature ,SOUTH African economy, 1991- ,EMERGING markets ,BUSINESS valuation - Abstract
In this study a market-based approach was adopted to investigate the valuation performance of 16 multiples over 28 sectors in the South African market. The market-based approach facilitates/enables an evaluation of the ability of multiplesbased modeling to approximate actual share prices on the JSE Securities Exchange. In addition, this study employs principal component analysis-based biplots and correlation monoplots to illustrate the relative valuation performance amongst all 16 multiples over all 28 sectors. The evidence suggests the following: Firstly, none of the peer group variables offered evidence to suggest that they were the optimal choice across all 28 sectors, which implies that the optimal choice of peer group variable is sector-specific, i.e. each of the 28 sectors may have a different optimal peer group variable. Secondly, the superior valuation performance of multiples whose peer groups were based on a combination of valuation fundamentals, as suggested in the finance literature, does not hold on a per sector basis. Thirdly, it was established which multiples, whose construction was based on an optimal peer group variable, performed the most accurate equity valuations in each of the 28 sectors in the South African market. Lastly, to this end, a sector value chain was subsequently created, which ranked each of the 16 multiples according to the valuation precision they exhibited in each of the 28 sectors. The sector value chain, which reflects substantial potential precision gains, ranging from 43.27% to 218.33%, also presents a synopsis of the sector-specific optimal peer group variables to be used in each of the 28 sectors, and provides an empirical guide to analysts in this respect.

Lindeque, B G and Nel, W S
- Abstract
Objectives. This report analyses the outcome and complications of 262 consecutive sacrocolpopexy procedures for the repair of vaginal vault prolapse and enterocele. Methods. From March 1994 to February 2001, 262 patients underwent surgical repair using a standardised retroperitoneal technique. Initially dura mater strips were used and from the 19th patient onwards, Gore-tex soft tissue patch was used to suspend the vaginal apex to the anterior sacral ligament. Halban-type occluding sutures were placed in the pouch of Douglas. All patients were followed up and the minimum duration of follow-up was 16 months. Results. Vaginal vault prolapse was successfully managed in 259 of 262 patients giving a success rate of 98.8%. In addition, 4 patients had a repeat enterocele that required surgical repair. The overall surgical complication rate was low. Erosion of the patch through the vaginal vault occurred in 10 patients, necessitating removal of the patch. Prolapse did not recur in any of these patients. Conclusion. Abdominal sacrocolpopexy is a very successful and safe surgical management of vaginal vault prolapse.

This paper investigates the valuation performance of 16 individual value drivers, from five different value driver categories, in relation to the South African equity market for the period 2001-2010. The research results revealed, among other findings, that headline earnings is by far the most accurate value driver and that, contrary to popular belief, earnings before interest, tax, depreciation and amortization and earnings before interest and tax are only fourth and fifth best alternatives. The evidence also suggests that, when employing multiples to perform equity valuations, a careful selection of value drivers could increase valuation accuracy by as much as 50.03%.
