Karl Barth's role in church and politics from 1930 to 1935

Karl Barth saw in natural theology a threat to the church of Christ. He was convinced that the so-called “German Christians” under the influence of the National Socialist Party practised natural theology. He advocated the need for the church of Christ to be church according to the Word of God. The church can be true church of Christ when it listens to and obeys the true calling of God. Barth's critique of an exclusive “Volkskirche” can serve as a corrective for the definition of the Nederduitsch Hervormde Kerk as a “volkskerk”.HTS Theological Studies Vol. 63 (4) 2007: pp. 1613-164

Prevalence of diabetes mellitus in the rural southern Free State

Background: A worldwide increase in the prevalence of diabetes mellitus (DM) has been reported and an even further increase is expected as a result of lifestyle changes. The objectives of this study were to determine the prevalence of DM in the rural southern Free State and to investigatethe contribution of risk factors such as age, physical activity, body mass index (BMI), waist-to-hip ratio and waist circumference to the developmentof impaired fasting glucose (IFG) or DM.Methods: Fasting venous plasma glucose (FVPG) levels were obtained from a total of 552 participants from Springfontein (n = 195), Trompsburg (n = 162) and Philippolis (n = 180). Participants were between 25 and 64 years of age, with 28.1% male (mean age 47.3 years) and 71.9% female (mean age 46 years). Anthropometric status was determined using standardised techniques. Levels of physical activity were determined using a 24-hour recall of physical activity as well as frequency of performing certain activities. Relative risks (RR) as well as 95% confidence intervals (95%CI) were used to distinguish significant risk factors for having IFG or DM.Results: In the study population the prevalence of DM was 7.6% (5.2% in men and 8.6% in women) and that of IFG was 6.3% (4.5% in men and 7.1% in women). The majority of nondiabetic (34%), IFG (55%) and DM (61%) participants were between the ages of 51 and 60 years. Age was found to be a statistically significant risk factor for having IFG or DM in participants older than 40 years of age (RR 2.3; 95% CI [1.22; 4.34]). Crude measurements (not age- and gender-adjusted) of waist circumference (RR 3.23; 95% CI [1.82; 5.74]), BMI (RR 2.32; 95% CI [1.43; 3.78]) and waist-to-hip ratio (RR 2.51; 95% CI [1.55; 4.07]) were statistically significant risk factors for having IFG or DM. Physical inactivity in men ≥ 40 years was also a statistically significant risk factor (RR 3.23; 95% CI [1.15; 9.05]) for having IFG or DM.Conclusions: In this study, 37.5% of diabetics were newly discovered. A high waist circumference, BMI and waist-to-hip-ratio were associated withan increased risk for developing IFG or DM, with a high waist circumference being the most significant general risk factor. Physically inactive men(≥ 40 years) were also at a higher risk of having IFG or DM. Follow-up FVPG and glucose tolerance tests should be performed on participants in the IFG group. A need for intervention regarding the identification and treatment of DM in these rural areas has been identified.Keywords: impaired fasting glucose; diabetes; risk factors; rura

risk-factor profile for chronic lifestyle diseases in three rural Free State towns

Background: Chronic diseases of lifestyle account for millions of deaths each year globally. These diseases share similar modifiable risk factors, including hypertension, tobacco smoking, diabetes, obesity,  hyperlipidaemia and physical inactivity. In South Africa the burden of noncommunicable disease risk factors is high. To reduce or control as many lifestyle risk factors as possible in a population, the distinct risk-factor profile for that specific community must be identified. Therefore, the aim of this study was to assess the health status in three rural Free State communities and to identify a distinct risk-factor profile for chronic lifestyle diseases in these communities.Methods: This study forms part of the baseline phase of the Assuring Health for All in the Free State project, which is a prospective and longitudinal epidemiological study aimed at determining how living in a rural area can either protect or predispose one to developing chronic lifestyle diseases. The communities of three black and coloured, rural Free State areas, namely Trompsburg, Philippolis and Springfontein, were evaluated. The study population consisted of 499 households, and 658 individuals (including children) participated in the study. Only results of adult participants between 25 and 64 years will be reported in this article. The study group consisted of 29.4% male and 70.6% female participants, with a mean age of 49 years. During interviews with trained researchers, household socio-demographic questionnaires, as well as individual  questionnaires evaluating diet, risk factors (history of hypertension and/or diabetes) and habits (tobacco smoking and physical activity levels), were completed. All participants underwent anthropometric evaluation, medical examination and blood sampling to determine fasting blood glucose levels.Results: Multiple risk factors for noncommunicable diseases were identified in this study population, including high blood pressure, tobacco smoking,high body mass index (BMI), diabetes and physical inactivity. The reported risk-factor profile was ranked. Increased waist circumference was rankedhighest, high blood pressure second, tobacco smoking third, physical inactivity fourth and diabetes fifth. The cumulative risk-factor profile revealed that 35.6 and 21% of this study population had two and three risk factors, respectively.Conclusions: The study demonstrated a high prevalence of risk factors for noncommunicable diseases, e.g. large waist circumference, high BMI,raised blood pressure, tobacco smoking and raised blood glucose levels. Serious consideration should be given to this escalating burden of lifestylediseases in the study population. The development and implementation of relevant health promotion and intervention programmes that will improvethe general health and reduce the risk for noncommunicable diseases in this population are advised.Keywords: risk; lifestyle; chronic disease

Downregulation of pyrophosphate: d-fructose-6-phosphate 1-phosphotransferase activity in sugarcane culms enhances sucrose accumulation due to elevated hexose-phosphate levels

Analyses of transgenic sugarcane clones with 45–95% reduced cytosolic pyrophosphate: d-fructose-6-phosphate 1-phosphotransferase (PFP, EC 2.7.1.90) activity displayed no visual phenotypical change, but significant changes were evident in in vivo metabolite levels and fluxes during internode development. In three independent transgenic lines, sucrose concentrations increased between three- and sixfold in immature internodes, compared to the levels in the wildtype control. There was an eightfold increase in the hexose-phosphate:triose-phosphate ratio in immature internodes, a significant restriction in the triose phosphate to hexose phosphate cycle and significant increase in sucrose cycling as monitored by 13C nuclear magnetic resonance. This suggests that an increase in the hexose-phosphate concentrations resulting from a restriction in the conversion of hexose phosphates to triose phosphates drive sucrose synthesis in the young internodes. These effects became less pronounced as the tissue matured. Decreased expression of PFP also resulted in an increase of the ATP/ADP and UTP/UDP ratios, and an increase of the total uridine nucleotide and, at a later stage, the total adenine nucleotide pool, revealing strong interactions between PPi metabolism and general energy metabolism. Finally, decreased PFP leads to a reduction of PPi levels in older internodes indicating that in these developmental stages PFP acts in the gluconeogenic direction. The lowered PPi levels might also contribute to the absence of increases in sucrose contents in the more mature tissues of transgenic sugarcane with reduced PFP activity

Article 59.1, of the International Code of Nomenclature for Algae, Fungi, and Plants (ICN; Melbourne Code), which addresses the nomenclature of pleomorphic fungi, became effective from 30 July 2011. Since that date, each fungal species can have one nomenclaturally correct name in a particular classification. All other previously used names for this species will be considered as synonyms. The older generic epithet takes priority over the younger name. Any widely used younger names proposed for use, must comply with Art. 57.2 and their usage should be approved by the Nomenclature Committee for Fungi (NCF). In this paper, we list all genera currently accepted by us in Dothideomycetes (belonging to 23 orders and 110 families), including pleomorphic and non-pleomorphic genera. In the case of pleomorphic genera, we follow the rulings of the current ICN and propose single generic names for future usage. The taxonomic placements of 1261 genera are listed as an outline. Protected names and suppressed names for 34 pleomorphic genera are listed separately. Notes and justifications are provided for possible proposed names after the list of genera. Notes are also provided on recent advances in our understanding of asexual and sexual morph linkages in Dothideomycetes. A phylogenetic tree based on four gene analyses supported 23 orders and 75 families, while 35 families still lack molecular data

Coherent ultrafast lattice-directed reaction dynamics of triiodide anion photodissociation

Solid-state reactions are influenced by the spatial arrangement of the reactants and the electrostatic environment of the lattice, which may enable lattice-directed chemical dynamics. Unlike the caging imposed by an inert matrix, an active lattice participates in the reaction, however, little evidence of such lattice participation has been gathered on ultrafast timescales due to the irreversibility of solid-state chemical systems. Here, by lowering the temperature to 80 K, we have been able to study the dissociative photochemistry of the triiodide anion (I₃−) in single-crystal tetra-n-butylammonium triiodide using broadband transient absorption spectroscopy. We identified the coherently formed tetraiodide radical anion (I₄•−) as a reaction intermediate. Its delayed appearance after that of the primary photoproduct, diiodide radical I₂•−, indicates that I₄•− was formed via a secondary reaction between a dissociated iodine radical (I^•) and an adjacent I₃−. This chemistry occurs as a result of the intermolecular interaction determined by the crystalline arrangement and is in stark contrast with previous solution studies
