Rescaling White Space in Post‐apartheid Johannesburg
Authors: Clarno Andy 
Published: March 2013

AbstractThis paper traces three political mobilizations in the wealthy suburbs of Johannesburg: a boycott of redistributive tax policies, the creation of gated communities and residents’ associations, and the demand for residential city improvement districts (CIDs). I argue that state rescaling and networked governance are constituted through struggles over governmental power. I also argue for more attention to race in the political economy of scale. Struggles over the scalar, networked, and territorial dimensions of governance are constitutive moments in the shifting articulation of race, class, and space. An analysis of articulation highlights the role of territory, identity and imagination in the production of space, demonstrates that neoliberal forms of networked governance are products of struggle, and reiterates the feminist argument that governmental interventions are about more than just capital accumulation.

AbstractIn this study, we compared the developmental ability of somatic cell nuclear transfer (SCNT) embryos reconstructed with three bovine somatic cells that had been synchronized in G0‐phase (G0‐SCNT group) or early G1‐phase (eG1‐SCNT group). Furthermore, we investigated the production efficiency of cloned offspring for NT embryos derived from these donor cells. The G0‐phase and eG1‐phase cells were synchronized, respectively, using serum starvation and antimitotic reagent treatment combined with shaking of the plate containing the cells (shake‐off method). The fusion rate in the G0‐SCNT groups (64.2 ± 1.8%) was significantly higher than that of eG1‐SCNT groups (39.2 ± 1.9%) (P < 0.05), but the developmental rates to the blastocyst stage of SCNT embryos per fused oocytes were similar for all groups. The overall production efficiency of the clone offspring in eG1‐SCNT groups (12.7%) per recipient cow was higher than that in G0‐SCNT groups (3%) (P < 0.05). The mean birth weight of cloned calves and the average calving score in the G0‐SCNT groups (48.1 ± 3.4 kg and 3.3 ± 0.3, respectively) was significantly higher (P < 0.05) than those of eG1‐SCNT groups (37.2 ± 2.1 kg and 2.3 ± 0.2, respectively). Results of this study indicate that synchronization of donor cells in eG1‐phase using the shake‐off method improved the overall production efficiency of the clone offspring per transferred embryo.

AbstractThe purpose of this study was to assess an evaluation method using an artificial taste sensor, in comparison with chemical analysis and sensory evaluation of the taste of meat during curing. Samples of Canadian pork were treated with salt, nitrite and phosphate. Curing time ranged from 0 to 168 h. In the sensory evaluation, there were no significant differences in the all characteristic items at 72‐h cured sample compared to the 0‐h sample. Some of the characteristic items for the 168‐h sample (umami, overall taste, richness and overall palatability) showed significant difference (P < 0.05) compared to the 0‐h sample. Taste sensor analysis indicated that the sensor outputs of bitterness and saltiness were significantly correlated with curing time (R = 0.98 and 0.97, respectively), and total free amino acids (R = 0.91 and 0.96, respectively). The sensor output of bitterness was significantly correlated (R = 0.96) with the sum of amino acids corresponding to bitter taste. The increase in the chemical components contributing to bitterness and/or saltiness was indicated as the cause of the characteristic taste. Taste sensor analysis may be applicable as a qualitative method for evaluating taste characteristics generated during the curing of manufactured cooked meat products.

AbstractWomen recover faster from propofol anaesthesia and have been described to have a higher incidence of awareness during surgery, compared to men – an effect that may be inherent in sex differences in propofol metabolism. In an observational study, 98 ASA I‐II patients treated with continuous propofol infusion were recruited. The associations between sex and CYP2B6 and UGT1A9 polymorphisms with dose‐ and weight‐adjusted area under the total plasma level time curves (AUC) for propofol, and its metabolites propofol glucuronide (PG), 4‐hydroxypropofol (OHP) and hydroxyl glucuronide metabolites 4‐hydroxypropofol‐1‐O‐β‐D‐glucuronide (Q1G) and 4‐hydroxypropofol‐4‐O‐β‐D‐glucuronide (Q4G), were analysed. Significantly higher AUC of PG (1.3 times, p = 0.03), Q1G (2.9 times, p < 0.001), Q4G (2.4 times, p < 0.01) and OHP (4.6 times, p = 0.01) were found in women (n = 53) than in men (n = 45) after intravenous infusion of propofol using target‐controlled infusion system. There was, however, no significant impact of gene polymorphisms on propofol biotransformation. The results, which are supported by a previous pilot study using a propofol bolus dose, suggest that, compared to men, more rapid propofol metabolism may occur in women – a factor that may contribute to the mentioned differences in the efficacy of propofol anaesthesia between male and female patients.

Published: March 2013

AbstractBackgroundInduction of labor, an increasingly common intervention, is often preceded by the application of an agent to “prime” or “ripen” the cervix. We conducted a randomized controlled trial to compare clinical, economic, and psychosocial outcomes of inpatient and outpatient cervical priming before induction of labor. In this paper we present the psychosocial outcomes.MethodsWomen participating in a randomized controlled trial in two Australian metropolitan teaching hospitals completed questionnaires to measure anxiety and depression at enrollment, and to examine satisfaction, experiences, depression, and infant feeding 7 weeks after giving birth. Data analysis was by intention to treat and by having received the intervention as intended (approximately 50% in each group).ResultsOf 1,004 eligible women, 85 percent consented (n = 407, outpatient; n = 414 inpatient). No statistically significant or clinically relevant differences were found in immediate anxiety, depression, or infant feeding. Small, statistically significant differences favoring outpatient priming were found in seven of the nine subscales in the 7‐week postpartum questionnaire. The direction of the effect was maintained, mostly with a larger effect size in women who received the intervention.ConclusionWomen allocated to outpatient priming were more satisfied with their priming experience than women allocated to inpatient priming. Being informed that they could go home after cervical priming did not increase women's anxiety.

AbstractBackgroundAntenatal smoking cessation guidelines have been available in Victoria, Australia, for the past decade. The objective of this study was to assess to what extent introduction of smoking cessation guidelines in pregnancy changed practice in Victorian public hospitals.MethodsTwo population‐based postal surveys of women giving birth in the state of Victoria, conducted in 2000 and 2008 before and after implementation of smoking cessation guidelines. Self‐administered questionnaires were distributed by hospitals and home birth practitioners to women 5–6 months postpartum.ResultsSurveys were completed and returned by 67 percent of eligible women (1,616/2,412) in 2000 and 51% (2,900/5,681) in 2008. Compared with the 2000 survey, women in the 2008 survey attending public sector care were more likely: to receive advice on how to stop smoking (Adjusted Odds Ratio: 2.2, 95% CI 1.5–3.2); to be given written information (Adj OR: 2.7, 95% CI 1.8–4.0); to be referred to stop smoking programs (Adj OR: 6.1, 95% CI 3.1–11.7); and to have discussed smoking cessation at more than one visit (Adj OR: 1.5, 95% CI 1.0–2.2). While the majority of women in both surveys were asked about smoking in early pregnancy, about half of those smoking did not receive advice on how to stop or cut down; were not given written information; were not told about/referred to stop smoking programs and were not asked again about smoking at subsequent visits. The significant shift in women's reports of receiving smoking cessation advice and support between the two surveys occurred predominantly at public hospitals where women received all or some antenatal care.ConclusionsSmoking cessation guidelines in Victorian public hospitals have increased the extent to which pregnant women receive advice and support to stop or reduce smoking. However, half of smokers did not receive the full complement of advice and support according to state guidelines, with marked variability according to where and from whom women received antenatal care. Further efforts are needed to implement smoking cessation advice and support in clinical practice.
Polyodontia in donkeys

Published: March 2013

SummaryPolyodontia is defined as the presence of teeth in excess of the normal dental formula. In equids, supernumerary teeth are uncommon but, when present, are usually located mainly in the caudal aspects of the cheek teeth rows (distomolars), also being found adjacent to normal cheek teeth or even in an ectopic location. It is believed that this disorder is a result of an inappropriate differentiation of dental germinal tissue during gestational development, with external trauma also acting as an initiating factor, when teeth germs are affected. The presence of these abnormal teeth can lead to axial displacement, dental overgrowths, dental‐related soft tissue damage, diastemata formation, periodontal disease and development of secondary sinusitis. A large prospective, cross‐sectional study was performed in 800 donkeys, with the aim to investigate the prevalence and aetiopathogenesis of clinically diagnosed oral and dental disorders. Polyodontia was recorded in 2.25% of the donkeys, presenting 36 supernumerary teeth, with 2.80% being incisors and 97.20% cheek teeth, with prevalence increasing with age. The caudal aspects of the maxillary cheek teeth rows were the most common locations for supernumerary teeth development (distomolars). The mandible was far less commonly affected than the maxilla. Although polyodontia is uncommon in donkeys, it should be considered in the differential diagnosis of dental disease. A methodical oral examination and a complete radiographic survey of the entire dental arcades are crucial for a correct early diagnosis and treatment plan implementation. The increasing prevalence of fully erupted supernumerary teeth recorded in older groups suggested a late onset eruption process, and therefore, in donkeys undergoing regular dental prophylaxis, the presence of previously unnoticed supernumerary teeth should always be sought.
Gdf6 induces commitment of pluripotent mesenchymal C3H10T1/2 cells to the adipocyte lineage

Mesenchymal stem cells have the potential to undergo commitment and differentiation into a variety of cell types, including osteoblasts, chondrocytes, myocytes and adipocytes. Growth differentiation factor 6 (Gdf6) is a member of the transforming growth factor β superfamily. We have examined the potential role of Gdf6 in adipogenesis of mesenchymal stem cells, and found that over‐expression of Gdf6 induced commitment of pluripotent mesenchymal C3H10T1/2 cells to the adipocyte lineage. The type I receptor Bmpr1a and the type II receptors Bmpr2 and Acvr2a mediate the Gdf6 signaling pathway. RNAi silencing of Smad4 and p38 MAPK suggested that both Smad and p38 MAPK pathways are involved in this process. The expression of Runx1t1 was down‐regulated in committed pre‐adipocytes, and forced expression of Runx1t1 blocked the adipocytic commitment. The results demonstrate a role for Gdf6 in adipocytic commitment and differentiation.

Published: March 2013

AbstractSwitchgrass (Panicum virgatum L.) is a C4 grass with high biomass yield potential and is now a model species for the Bioenergy Feedstock Development Program. Two distinct ecotypes (e.g., upland and lowland) and a range of plant morphotypes (e.g., leafy and stemmy) have been observed in switchgrass. The objective of this study was to determine the influence of ecotype and morphotype on biomass feedstock quality. Leaf and stem tissues of leafy and stemmy morphotypes from both lowland and upland ecotypes were analyzed for key feedstock traits. The leaf : stem ratio of leafy morphotype was more than 40% higher than the stemmy morphotype in both upland and lowland ecotypes. Therefore, the stemmy morphotype has significant advantages over leafy morphotype during harvesting, storage, transportation and finally the feedstock quality. Remarkable differences in feedstock quality and mineral composition were observed in switchgrass genotypes with distinct ecotypic origins and variable plant morphotypes. Lignin, hemicelluloses and cellulose concentrations were higher in stems than in the leaves, while ash content was notably high in leaves. A higher concentration of potassium was found in the stems compared to the leaves. In contrast, calcium was higher and magnesium was generally higher in the leaves compared to stems. The upland genotypes demonstrated considerably higher lignin (14.4%) compared with lowland genotypes (12.4%), while hemicellulose was higher in lowland compared with upland. The stemmy type demonstrated slightly higher lignin compared with leafy types (P < 0.1). Differences between the ecotypes and morphotypes for key quality traits demonstrated the potential for improving feedstock composition of switchgrass through selection in breeding programs.

AbstractNeutrophil‐to‐lymphocyte ratio (NLR) was introduced as a potential marker to determine inflammation in end‐stage renal disease (ESRD) patients. Recently, platelet‐to‐lymphocyte ratio (PLR) and NLR were found to positively correlated with inflammatory markers including tumor necrosis factor‐α (TNF‐α) and interleukin (IL)‐6 in cardiac and noncardiac patients. Data regarding PLR and its association with inflammation are lacking in hemodialysis (HD) and peritoneal dialysis (PD) patients. Hence, we aimed to determine the relationship between PLR, NLR, and inflammation in ESRD patients. This was a cross‐sectional study involving 62 ESRD patients (29 females, 33 males; mean age, 49.6 ± 14.6 years) receiving PD or HD for ≥6 months in the Dialysis Unit of Necmettin Erbakan University. PLR, NLR, C‐reactive protein, TNF‐α, IL‐6 levels were measured. PLR, NLR, serum high sensitive C‐reactive protein, IL‐6, and TNF‐α levels were significantly higher in PD patients when compared with HD patients. ESRD patients with PLR ≥ 140 had significantly higher NLR, IL‐6, and TNF‐α levels when compared to patients with PLR < 139. In the bivariate correlation analysis, PLR was positively correlated with NLR, IL‐6, and TNF‐α in this population. When we compared the association of PLR and NLR with IL‐6 (r = 0.371, P = 0.003 vs. r = 0.263, P = 0.04, respectively) and TNF‐α (r = 0.334, P = 0.008 vs. r = 0.273, P = 0.032, respectively), PLR was found to be superior to NLR in terms of inflammation in ESRD patients. Simple calculation of PLR can predict inflammation better than NLR in ESRD patients.
Sincerity Silencing
Authors: Mcgowan Mary Kate 
Published: March 2013

Catharine MacKinnon claims that pornography silences women in a way that violates the right to free speech. This claim is, of course, controversial, but if it is correct, then the very free speech reasons for protecting pornography appear also to afford reason to restrict it. For this reason, it has gained considerable attention.The philosophical literature thus far focuses on a type of silencing identified and analyzed by Jennifer Hornsby and Rae Langton (H&L). This article identifies, analyzes, and argues for the importance of a different type of silencing.As we shall see, there are compelling reasons in favor of regarding H&L silencing as a free speech violation and, as I argue here, the same can be said for sincerity silencing. Although additional work needs to be done to show that either one actually is a free speech violation, I demonstrate here that both types of silencing equally warrant this further attention. Moreover, I show that sincerity silencing is a fairly widespread phenomenon; so, therefore, is the harm it constitutes. As a result of these considerations, then, we can safely conclude that sincerity silencing also requires our attention.

A violet divalent europium‐doped strontium aluminate (Sr–Al–O:Eu2+) phosphor particle was synthesized from a metal‐ethylenediaminetetraacetic acid (EDTA) solution of Sr, Al, Eu, and particulate alumina via spray drying and sintering in a reducing atmosphere. The emission properties, crystal structures, cross‐sectional emissions, and elemental distributions of the obtained Sr–Al–O:Eu2+ phosphor particles were investigated. The product was determined to be secondary SrAl12O19:Eu2+ particles with an average diameter of 20 μm. The violet SrAl12O19:Eu2+ emission phase was found in a 1‐μm‐thick coating of the particles where elemental Al diffusion occurred. These particles are anticipated to find commercial applications such as paints.

SummaryFactors able to modulate chelating factors, trace minerals and their bioavailability were investigated in porridges of five sorghum (Sorghum bicolor (L.) Moench) varieties: from Nigeria, Senegal, Burkina Faso and two from Italy. Effects of variety and traditional fermentation and cooking were assessed on iron‐binding phenolic groups, phytates and iron and zinc content and bioavailability. Chelating factors, trace elements as well as the effect of processing (mainly fermentation) were modulated by variety. Fermentation decreased iron‐binding phenolic groups until 49% and phytate content until 72% as well as increased phytase activity 3.4–16.4 fold, leading to enhancement of iron and zinc estimated bioavailability. Cooking alone had almost no effect. The lowest chelating factors content and the highest trace minerals bioavailability were shown by fermented Senegal landrace, whereas the Italian varieties overall showed the worst results. The results indicate that selection of traditional varieties and appropriate processing methods can improve sorghum nutritional value.

SummaryChanges in the physicochemical and sensory characteristics of commercial whole, pitted and stuffed with pepper, garlic or anchovy paste Spanish‐style green table olives of the Gordal, Manzanilla and Hojiblanca cultivars were studied during a three‐year period. No olives developed any spoilage during this period, and at the end of it, all presentations were classified as ‘extra’ according to the sensory evaluation methodology issued by the International Olive Council. Throughout the shelf‐life, surface colour index and firmness of the olives degraded in accordance with a first‐order kinetics, while a gradual browning of the cover brines was observed; however, products added with ascorbic acid maintained a stable colour, while those with calcium content showed reduced firmness degradation. No significant changes in most of the sensory characteristics were observed by the panel test during shelf‐life and only slight changes in firmness, and surface colour were noticed in samples with significant differences in these attributes when measured instrumentally.

AbstractThe aim of the present study was to evaluate the oncological outcomes of radical cystectomy followed by orthotopic urinary diversion in male patients with urothelial bladder carcinoma involving prostatic stroma (pT4a). A total of 1964 patients with urothelial bladder carcinoma who underwent cystectomy between 1971 and 2008 were retrospectively analyzed. Among them, male patients with pT4aN0M0 disease at cystectomy and orthotopic urinary diversion were identified and included in the analysis. Exclusion criteria were perioperative mortality and primary urethrectomy. The outcomes were urethral recurrence, local recurrence, recurrence‐free survival and overall survival. Univariate and log–rank statistics were used to examine associations between variables and outcome. A total of 33 patients (1.7%) entered the study with a median age of 71 years. Median follow up was 4.8 years (range 0.1–21 years). A total of two urethral recurrences (6%) occurred at a median of 2.4 years after cystectomy. No patient had local recurrence. The 5‐year recurrence‐free survival and overall survival was 56% ± 10% and 56% ± 9%, respectively. The probability of urethral and local recurrence after orthotopic diversion in pT4a urothelial bladder carcinoma patients is low. Thus, orthotopic urinary diversion appears to be oncologically safe in this patient population.
