    In order for olives of the Manzanilla variety to be produced as Spanish-style, they require a previous storage period before their alkaline treatment with NaOH. This holding time prevents the breakage and shedding of the fruit epidermis, but at the same time, causes an increase in the number of olives with surface blemishes and, consequently, loss in product quality. The objectives of this work were to investigate, at industrial scale, different alternatives to the holding period; specifically, the use of low-concentration alkaline solutions before the real alkaline treatment, and the use of alkaline solutions at low temperatures for this alkaline treatment. Basic parameters of the fermentative processes carried out in every treatment were monitored, and commercial quality of the final product was ascertained. The results indicate that both modifications are alternatives to the traditional treatment, and the products obtained applying these modifications have the same or higher quality than those obtained by the traditional process.Las aceitunas Manzanillas, para su elaboración estilo español, precisan de un periodo previo de reposo de los frutos antes del cocido o tratamiento alcalino con NaOH. Este periodo de reposo evita la rotura y desprendimiento de epidermis de los frutos pero, al mismo tiempo, provoca un aumento en el número de aceitunas con manchas superficiales y, consecuentemente, pérdida de calidad del producto. Los objetivos del presente trabajo fueron investigar, a escala industrial, alternativas al reposo previo; concretamente, la utilización de soluciones alcalinas de baja concentración antes del cocido y realizar este último con soluciones a temperatura reducida. Se analizaron los parámetros fundamentales de los procesos fermentativos obtenidos en cada caso y se determinó la calidad comercial de los productos finales. Los resultados obtenidos indican que ambas modificaciones constituyen alternativas al tratamiento tradicional con las que se obtienen productos de igual o superior calidad

    A method for visualising fluorescence of flavonoid therapeutics in vivo in the model eukaryote Dictyostelium discoideum

    Naturstoff reagent A (diphenylboric acid 2-aminoethyl ester, DPBA) has been used historically in plant science to observe polyphenolic pigments, such as flavonoids, whose fluorescence requires enhancement to be visible by microscopy. Flavonoids are common dietary constituents and are the focus of considerable attention because of their potential as novel therapies for numerous diseases. The molecular basis of therapeutic activity is only gradually being established, and one strand of such research is making use of the social amoeba Dictyostelium discoideum. We extended the application of DPBA to flavonoid imaging in these preclinical studies and report the first method for use of DPBA in this eukaryotic model microbe, and its applicability alongside subcellular markers. This in vivo fluorescence imaging provided a useful adjunct to parallel chemical and genetic studies

    Large-Scale Controls of the Surface Water Balance Over Land-Insights From a Systematic Review and Meta-Analysis

    The long-term surface water balance over land is described by the partitioning of precipitation (P) into runoff and evapotranspiration (ET), and is commonly characterized by the ratio ET/P. The ratio between potential evapotranspiration (PET) and P is explicitly considered to be the primary control of ET/P within the Budyko framework, whereas all other controls are often integrated into a single parameter, ω. Although the joint effect of these additional controlling factors of ET/P can be significant, a detailed understanding of them is yet to be achieved. This study therefore introduces a new global dataset for the long-term mean partitioning of P into ET and runoff in 2733 catchments, which is based on in-situ observations and assembled from a systematic examination of peer-reviewed studies. A total of 26 controls of ET/P that are proposed in the literature are assessed using the new dataset. Results reveal that: (i) factors controlling ET/P vary between regions with different climate types; (ii) controls other than PET/P explain at least 35% of the ET/P variance in all regions, and up to ∼90% in arid climates; (iii) among these, climate factors and catchment slope dominate over other landscape characteristics; and (iv) despite the high attention that vegetation-related indices receive as controls of ET/P, they are found to play a minor and often non-significant role. Overall, this study provides a comprehensive picture on factors controlling the partitioning of P, with valuable insights for model development, watershed management, and the assessment of water resources around the globe

    Background: There is a substantial gap in provision of adequate surgical care in many low-and middle-income countries. This study aimed to identify the economic burden of unmet surgical need for the common condition of appendicitis. Methods: Data on the incidence of appendicitis from 170 countries and two different approaches were used to estimate numbers of patients who do not receive surgery: as a fixed proportion of the total unmet surgical need per country (approach 1); and based on country income status (approach 2). Indirect costs with current levels of access and local quality, and those if quality were at the standards of high-income countries, were estimated. A human capital approach was applied, focusing on the economic burden resulting from premature death and absenteeism. Results: Excess mortality was 4185 per 100 000 cases of appendicitis using approach 1 and 3448 per 100 000 using approach 2. The economic burden of continuing current levels of access and local quality was US 92492millionusingapproach1and92 492 million using approach 1 and 73 141 million using approach 2. The economic burden of not providing surgical care to the standards of high-income countries was 95004millionusingapproach1and95 004 million using approach 1 and 75 666 million using approach 2. The largest share of these costs resulted from premature death (97.7 per cent) and lack of access (97.0 per cent) in contrast to lack of quality. Conclusion: For a comparatively non-complex emergency condition such as appendicitis, increasing access to care should be prioritized. Although improving quality of care should not be neglected, increasing provision of care at current standards could reduce societal costs substantially

    Pooled analysis of WHO Surgical Safety Checklist use and mortality after emergency laparotomy

    Background The World Health Organization (WHO) Surgical Safety Checklist has fostered safe practice for 10 years, yet its place in emergency surgery has not been assessed on a global scale. The aim of this study was to evaluate reported checklist use in emergency settings and examine the relationship with perioperative mortality in patients who had emergency laparotomy. Methods In two multinational cohort studies, adults undergoing emergency laparotomy were compared with those having elective gastrointestinal surgery. Relationships between reported checklist use and mortality were determined using multivariable logistic regression and bootstrapped simulation. Results Of 12 296 patients included from 76 countries, 4843 underwent emergency laparotomy. After adjusting for patient and disease factors, checklist use before emergency laparotomy was more common in countries with a high Human Development Index (HDI) (2455 of 2741, 89.6 per cent) compared with that in countries with a middle (753 of 1242, 60.6 per cent; odds ratio (OR) 0.17, 95 per cent c.i. 0.14 to 0.21, P <0001) or low (363 of 860, 422 per cent; OR 008, 007 to 010, P <0.001) HDI. Checklist use was less common in elective surgery than for emergency laparotomy in high-HDI countries (risk difference -94 (95 per cent c.i. -11.9 to -6.9) per cent; P <0001), but the relationship was reversed in low-HDI countries (+121 (+7.0 to +173) per cent; P <0001). In multivariable models, checklist use was associated with a lower 30-day perioperative mortality (OR 0.60, 0.50 to 073; P <0.001). The greatest absolute benefit was seen for emergency surgery in low- and middle-HDI countries. Conclusion Checklist use in emergency laparotomy was associated with a significantly lower perioperative mortality rate. Checklist use in low-HDI countries was half that in high-HDI countries.Peer reviewe

    Background End colostomy rates following colorectal resection vary across institutions in high-income settings, being influenced by patient, disease, surgeon and system factors. This study aimed to assess global variation in end colostomy rates after left-sided colorectal resection. Methods This study comprised an analysis of GlobalSurg-1 and -2 international, prospective, observational cohort studies (2014, 2016), including consecutive adult patients undergoing elective or emergency left-sided colorectal resection within discrete 2-week windows. Countries were grouped into high-, middle- and low-income tertiles according to the United Nations Human Development Index (HDI). Factors associated with colostomy formation versus primary anastomosis were explored using a multilevel, multivariable logistic regression model. Results In total, 1635 patients from 242 hospitals in 57 countries undergoing left-sided colorectal resection were included: 113 (6·9 per cent) from low-HDI, 254 (15·5 per cent) from middle-HDI and 1268 (77·6 per cent) from high-HDI countries. There was a higher proportion of patients with perforated disease (57·5, 40·9 and 35·4 per cent; P < 0·001) and subsequent use of end colostomy (52·2, 24·8 and 18·9 per cent; P < 0·001) in low- compared with middle- and high-HDI settings. The association with colostomy use in low-HDI settings persisted (odds ratio (OR) 3·20, 95 per cent c.i. 1·35 to 7·57; P = 0·008) after risk adjustment for malignant disease (OR 2·34, 1·65 to 3·32; P < 0·001), emergency surgery (OR 4·08, 2·73 to 6·10; P < 0·001), time to operation at least 48 h (OR 1·99, 1·28 to 3·09; P = 0·002) and disease perforation (OR 4·00, 2·81 to 5·69; P < 0·001). Conclusion Global differences existed in the proportion of patients receiving end stomas after left-sided colorectal resection based on income, which went beyond case mix alone

    Temporal enclosures and the social production of inescapable futures for coal mining in Colombia

    Full text link
    The creation of spatial enclosures is a well-developed subject in the study of extractive industries. Less attention has been given to the control of time and the future within these socio-spatial contexts. Based on ethnographic fieldwork, we followed two controversial projects aimed at expanding the biggest open-pit coal mine in Colombia, both of which implied diverting watercourses to extract coal from beneath their riverbed. We describe corporate strategies that give rise to what we call temporal enclosures, the process by which mining companies aim to restrict imaginable outcomes to those that favour them, producing the sense of a manageable and inescapable future in which forthcoming activities are presented as both inevitable and desirable. The temporal enclosure is configured discursively in practices of building engineered landscapes, refashioning relations between the mine and the people, and intensifying the language and practices of nurturing and caring for humans and non-humans around the operation area. However, in the context of increasing pressure regarding the consequences of extractive industries, the dispute over alternative futures becomes a highly relevant political site. We argue that this temporal dimension is interlinked with spatial, political, and economic dynamics around extractive industries and that understanding how temporal enclosures are produced and resisted is essential for envisioning sustainable alternatives

    Interconnectedness and financial stability

    Full text link
    The 2007&#x2013;2008 global financial crisis has been associated with a high level of connectivity in the global financial system. The crisis, and the following events of the past decade, have highlighted the relevance of the concept of interconnectedness to understanding systemic risk, transmission of financial contagion and ultimately on the subject of financial stability. Nevertheless, the more general relationship, across its full spectrum, between interconnectedness and financial stability, is still not fully studied and understood. This paper reviews the positive aspects as well as the negative aspects of interconnectedness. It also discusses briefly the important question of the optimal level of connectivity in a financial system. Finally, the paper proposes the use of novel statistical inferential methods for complex networks to address comprehensively the study of interconnectedness in financial systems
