Telomere length attrition, a marker of biological senescence, is inversely correlated with triglycerides and cholesterol in South Asian males with type 2 diabetes mellitus

South Asians have a higher risk of type 2 diabetes mellitus (T2DM) and cardiovascular disease (CVD) than white Caucasians, for a given BMI. Premature biological ageing, assessed by reduction in telomere length (TL), may be mediated by factors resulting from altered metabolic profiles associated with obesity. We hypothesise that ethnicity and metabolic status represent detrimental factors contributing to premature biological ageing. Therefore we assessed TL in two South Asian, age and BMI-matched cohorts [T2DM (n = 142) versus non-T2DM (n = 76)] to determine the effects of BMI, gender, lipid and CVD profile on biological ageing. Genomic DNA was obtained from the UKADS cohort; biochemical and anthropometric data was collected and TL was measured by quantitative real-time PCR. Our findings indicated a gender-specific effect with reduced TL in T2DM men compared with non-T2DM men (P = 0.006). Additionally, in T2DM men, TL was inversely correlated with triglycerides and total cholesterol (r = -0.419, P <0.01; r = -0.443, P <0.01). In summary, TL was reduced amongst South Asian T2DM men and correlated with triglycerides and total cholesterol. This study highlights enhanced biological ageing among South Asian, T2DM men, which appears to be tracked by changes in lipids and BMI, suggesting that raised lipids and BMI may directly contribute to premature ageing.

Premature cardiovascular events and mortality in south Asians with type 2 diabetes in the United Kingdom Asian Diabetes Study - effect of ethnicity on risk

Background/Aim - People of south Asian origin have an excessive risk of morbidity and mortality from cardiovascular disease. We examined the effect of ethnicity on known risk factors and analysed the risk of cardiovascular events and mortality in UK south Asian and white Europeans patients with type 2 diabetes over a 2 year period. Methods - A total of 1486 south Asian (SA) and 492 white European (WE) subjects with type 2 diabetes were recruited from 25 general practices in Coventry and Birmingham, UK. Baseline data included clinical history, anthropometry and measurements of traditional risk factors – blood pressure, total cholesterol, HbA1c. Multiple linear regression models were used to examine ethnicity differences in individual risk factors. Ten-year cardiovascular risk was estimated using the Framingham and UKPDS equations. All subjects were followed up for 2 years. Cardiovascular events (CVD) and mortality between the two groups were compared. Findings - Significant differences were noted in risk profiles between both groups. After adjustment for clustering and confounding a significant ethnicity effect remained only for higher HbA1c (0.50 [0.22 to 0.77]; P?=?0.0004) and lower HDL (-0.09 [-0.17 to -0.01]; P?=?0.0266). Baseline CVD history was predictive of CVD events during follow-up for SA (P?and short period of follow-up are key limitations. Longer follow-up is required to see if the observed differences between the ethnic groups persist. Conclusion - South Asian patients with type 2 diabetes in the UK have a higher cardiovascular risk and present with cardiovascular events at a significantly younger age than white Europeans. Enhanced and ethnicity specific targets and effective treatments are needed if these inequalities are to be reduced.

Postcolonial transitions in Africa:Decolonization in West Africa and present day South Africa

Black Economic Empowerment is a highly debated issue in contemporary South Africa. Yet few South Africans realize that they are following a postcolonial trajectory already experienced by other countries. This paper presents a case study of British firms during decolonization in Ghana and Nigeria in the 1950s and 1960s, which saw a parallel development in business and society to that which occurred in South Africa in the 1990s and 2000s. Despite fundamental differences between these states, all have had to empower a majority of black citizens who had previously suffered discrimination on the basis of race. The paper employs concepts from social capital theory to show that the process of postcolonial transition in African economies has been more politically and socially disruptive than empowerment in Western countries. Historical research contributes to our understanding of the nature of institutional shocks in emerging economies.

Haitians Released from Krome: Their Prospects for Adaptation and Integration in South Florida (Dialogue #24)

Excerpt from EXECUTIVE SUMMARY This report examines the situation of the Haitians in Miami who were formerly incarcerated during 1981 and 1982 in the Immigration and Naturalization Service's Krome Detention Center or other Federal detention centers in the U.S. and Puerto Rico. For convenience, the report refers to all of them as Krome Haitians. This study is based upon a sociological survey of the Krome Haitians and intensive anthropological fieldwork conducted by Dr. Alex Stepick of the Sociology and Anthropology Department of Florida International University with support from the Catholic Services Bureau of Miami. It is the only scientific study of the Krome Haitians and the scientific procedures of the survey complemented by the anthropological fieldwork combine t o produce highly reliable results . To provide context to the conditions of the Krome Haitians, the report compares the characteristics of this population to that of the Haitian Entrants who arrived in 1980 or earlier and provides an update to earlier studies by this author (Stepick 1982) and another by the Behavioral Science Research Institute (1983). The report describes the conditions of the Krome Haitians, including their background in Haiti, experiences in the U.S., past and present employment status , experience with discrimination and social isolation , and adaptation to American society. The report concludes with some specific policy recommendations to state and local agencies and individuals that will assist the Haitians' integration into American society.

Language maintenance and use in south Florida Hispanic university students: Do educational programs matter?

This study examined the long-term effects of bilingual education/ESOL instruction on Hispanic university students' subsequent Spanish language maintenance using sociolinguistic methodology as its framework. The study investigated whether or not Hispanic university students who had participated in bilingual or ESOL classes in their elementary schooling maintained Spanish as young adults. Maintenance included using Spanish in their personal and professional lives and demonstrating written competence in Spanish, as well as whether subjects considered themselves to be bilingual, how they rated their ability in different skill areas for the two languages, and if they exhibited positive attitudes toward language and education as compared to Hispanic students who had experienced an all English classroom situation. A Language and Education Survey was developed to collect data pertaining to these areas. ^ A convenience sample of 202 Hispanic undergraduate university students enrolled in education classes at Florida International University during the 2000–2001 academic year participated in the study. Subjects were grouped according to the type of program they had experienced at the elementary school level, Bilingual/ESOL and All English. ^ Statistically significant differences were found between the groups in subjects' self-ratings of their abilities in speaking, reading, writing, and comprehension. No statistically significant differences were found with respect to the continuation of Spanish language study at the secondary school or college levels although there was a significant difference in number of semesters for those who planned to do so. ^ In language use, there were statistically significant differences overall as there were in the personal domain, but none were found in the professional domain; nor were there any statistically significant differences between the groups with respect to attitudes regarding education and language. There were statistically significant differences between the two groups for communicative competence in written Spanish. These statistically significant findings in language ability, language use and written communicative competence indicated that Hispanic university students who were enrolled in bilingual programs/ESOL in their earlier schooling did maintain Spanish as their native language as compared to Hispanic students who did not participate in such programs. ^

Paleomagnetic measurements from four piston cores from the Agulhas ridge and Meteor Rise (South Atlantic)

We report relative paleointensity proxy records from four piston cores collected near the Agulhas Ridge and Meteor Rise (South Atlantic). The mean sedimentation rate of the cores varies from 24 cm/kyr to 11 cm/kyr. The two cores with mean sedimentation rates over 20 cm/kyr record positive remanence inclinations at 40-41 ka coeval with the Laschamp Event. Age models are based on oxygen isotope data from three of the cores, augmented by radiocarbon ages from nearby Core RC11-83, and by correlation of paleointensity records for the one core with no oxygen isotope data. The relative paleointensity proxy records are the first from the South Atlantic and from the high to mid-latitude southern hemisphere. Prominent paleointensity lows at ?40 ka and ?65 ka, as well as many other features, can be correlated to paleointensity records of comparable resolution from the northern hemisphere. The records are attributable, in large part, to the global-scale field, and therefore have potential for inter-hemispheric correlation at a resolution difficult to achieve with isotope data alone.

Granulometry, mineralogy and geochemistry of ODP Holes 184-1147A and 184-1148A, South China Sea

Green clay layers are reported from the Pliocene-Holocene intervals in five of the six sites drilled in the South China Sea (SCS) during Leg 184. Centimeter-scale discrete, discontinuous, and bioturbated layers, constituted by stiff and porous green clays, were observed, sometimes associated with iron sulfides and pyrite. Detailed mineralogical and geochemical analyses indicate that they differentiate from the host sediments in their higher content of iron, smectite, and mixed-layered clays and lower amounts of calcite, authigenic phosphorus, quartz, and organic matter. Although no glauconite was observed, the mineralogy and geochemistry of green clay layers, along with their geometrical relation to background sediments, suggest that they most likely represent the result of the first steps of glauconitization. Correlation between green layers and volcanic ash layers was suggested for green laminae observed elsewhere in Pacific sediments but was not confirmed at SCS sites. Statistical analysis of the temporal distribution of green layers in the records of the last million years suggests that green clay layers have become more frequent since 600 ka. Only at Site 1148 does the green layer record show a statistically significant cyclicity which may be related to orbital eccentricity. A possible influence of sea level variations, related both to climatic changes and tectonism, is postulated.

Developmental TVET rhetoric in-action: the White Paper for post-school education and training in South Africa

This paper explores the extent to which latest developments in the Technical and Vocational Education and Training System in South Africa respond to key principles espoused for a developmental, democratic and inclusionary ideal. The White Paper for post school education and training approved by Cabinet in November, 2013 is referred to by the Minister as the “definitive statement of the governments vision for the post school system” and as such represents a crucial strategy document intended to chart the TVET direction to 2030. Using key theoretical constructs from development theory, this paper provides an assessment of the TVET strategy contained is the paper and explores the extent to which it does respond to the agenda defined by the promise. It is argued that the challenges outlined are not yet able to provide the blueprint for a TVET transformative vision. It is concluded that while the development rhetoric contained in the paper is plausible, the creative tinkering of the system is unlikely to lead to the radical revisioning necessary for a truly transformative TVET system. The underlying assumptions regarding purpose, impact and outcome will need to be carefully reconsidered if the system is to be responsive to the promises of the democratic developmental ideal to which the government is committed.

Novana, its territory and the Pisa South Picenum Survey Project II

Si presenta in questa sede una sintesi dei risultati emersi dalle campagne 2014-2015 del Pisa South Picenum Survey Project II, relativo alle alte valli dei fiumi Aso e Tenna, nelle Marche meridionali. Dalle ricognizioni intensive effettuate nel territorio comunale di Amandola (Provincia di FM) è emerso un fitto popolamento rurale costituito da piccole fattorie, databili a partire dalla fine del III sec.a.C., e posizionate all’interno di una griglia centuriale. Questo territorio, con tutta probabilità viritim adsignatus a seguito della lex de agro Gallico et Piceno viritim dividundo del 232 a.C., doveva avvalersi di un polo di aggregazione sociale e amministrativa ubicato nelle vicinanze e ben collegato alla viabilità principale. La posizione strategica, un’accurata analisi dell’assetto centuriale e numerosi rinvenimenti archeologici permettono di identificare questa praefectura nell’area dell’attuale Comunanza dove possiamo localizzare l’antica Novana citata da Plinio (N.H., III, 11)., un centro piceno che divenne, forse, un foro, e poi una praefectura ed infine un municipium.

Ecotoxicological assessment of sediments from the Port of Santos and the disposal sites of dredged material

A dragagem dos sedimentos do Canal de Santos é necessária para permitir o trânsito de navios que operam no Porto de Santos. As áreas de disposição do material dragado estão situadas na zona costeira, em frente à Baía de Santos. Este estudo visou avaliar a qualidade dos sedimentos do Canal de Santos e das áreas de disposição atuais e antigas, utilizando testes de toxicidade de sedimento integral com anfípodos e de toxicidade de elutriatos com embriões de ouriço do mar. As amostras do Canal de Santos foram consideradas as mais tóxicas: todas as amostras dessa área foram consideradas significativamente tóxicas. Além disso, algumas amostras das áreas de disposição exibiram toxicidade. Os resultados mostraram, portanto, que os sedimentos apresentam evidências de degradação em sua qualidade, porém novos estudos devem ser conduzidos visando determinar as relações entre contaminação e toxicidade. Os resultados sugerem ainda que a disposição dos sedimentos dragados deva ser reavaliada.
