Bioavailability of procyanidin dimers and trimers and matrix food effects in in vitro and in vivo models
Authors: Serra Aida , Macià Alba , Romero Maria-Paz , Valls Josep , Bladé Cinta , Arola Lluís , Motilva Maria-José 
Published: December 2009

Among procyanidins (PC), monomers, such as catechin and epicatechin, have been widely studied, whereas dimer and trimer oligomers have received much less attention, despite their abundance in our diet. Recent studies have showed that as dimers and trimers could be important in determining the biological effects of procyanidin-rich food, understanding their bioavailability and metabolism is fundamental. The purpose of the present work is to study the stability of PC under digestion conditions, the metabolism and the bioavailability by using a combination of in vitro and in vivo models. Simultaneously, the matrix effect of a carbohydrate-rich food on the digestibility and bioavailability of PC is investigated. The results show a high level of stability of PC under gastric and duodenal digestion conditions. However, the pharmacokinetic study revealed limited absorption. Free forms of dimers and trimers have been detected in rat plasma, reaching the maximum concentration 1 h after oral intake of a grape seed extract.
What Determines the Length of a Typical Canadian Parliamentary Government?
Authors: Ferris J. Stephen , Voia Marcel-Cristian 
Published: December 2009

Abstract.In this paper we examine the length of political tenure in Canadian federally elected parliamentary governments since 1867. Using annual data on tenure length, we categorize the distribution of governing tenures in terms of a hazard function: the probability that an election will arise in each year, given that an election has not yet been called. Structuring the election call as an optimal stopping rule, we test whether that distribution responds predictably to characteristics of the political and/or economic environment. The results of using the continuous Cox and Gompertz models together with the discrete semi-parametric proportional hazard model suggest that governing parties in Canada do engage in election timing and that the only economic policy measure that is used consistently in conjunction with election timing is fiscal expenditure.Résumé.Dans cet ouvrage, nous examinons la durée d'un régime parlementaire canadien depuis la Confédération de 1867. Nous utilisons des données annuelles et nous représentons la distribution de durée de vie d'un gouvernement par une fonction de hazard, c'est-a-dire, la probabilité qu'une élection soit déclenchée durant une année spécifique étant donné qu'elle ne l'a pas encore été jusqu'à présent. Nous modélisons un déclenchement d'élection par une règle d'arrêt optimal el nous testons si la distribution dépend des caractéristiques de l'environnement politique et économique tel que prédit selon la théorie. Nous résultats basés les modèles de hazard proportionnel continu de type Cox et Gompertz et discret semi-paramétrique révèlent que les partis fédéraux au pouvoir au Canada choisissent le moment opportun pour déclencher une élection. De plus, les dépenses fiscales sont la seule variable de politique économique qui y soit systématiquement relié.
Disability Rights Activists in the Supreme Court of Canada: Legal Mobilization Theory and Accommodating Social Movements
Authors: Vanhala Lisa 
Published: December 2009

Abstract.Disability rights organizations have been active participants before the Supreme Court of Canada (SCC) since the mid-1980s but they have been completely neglected in the literature on social movement legal mobilization. This paper seeks to remedy this lacuna by providing an overview of the litigation activity of the main disability rights organizations. It builds on an emerging complementary theoretical perspective for understanding the participation by movement actors in the Court. Through an analysis of shared and contested collective meaning frames within and across social movement organizations we can complement existing theoretical explanations for the overall development of legal mobilization by social movement actors.Résumé.Les organismes du mouvement de défense des droits des personnes handicapées prennent une part active aux litiges devant la Cour suprême du Canada depuis le milieu des années quatre-vingt. Toutefois, on ne retrouve pas trace de ce mouvement dans la littérature sur la mobilisation des acteurs collectifs dans les lieux juridiques. Le présent article vient combler cette lacune en analysant les activités du mouvement dans ce domaine. L'article s'appuie sur une perspective théorique novatrice et complémentaire qui s'intéresse particulièrement aux rôles que jouent les idées organisationnelles et les relations intra-organisationnelles (conflictuelles ou de coopération) au sein du mouvement. L'article met de l'avant une explication qui combine ces deux facteurs pour mieux expliquer les tendances activistes de participation aux litiges par rapport aux analyses «classiques» qui ne prennent en compte que les ressources ou le contexte politique.
The sensitivity of United Kingdom health-care services to the diverse needs of Chinese-origin older people
Authors: CHAU RUBY C. M. , YU SAM WAI-KAM 
Published: December 2009

ABSTRACTThis paper is a contribution to the debate on how to make health-care services in the United Kingdom more responsive to the needs of older people who are members of recent immigrant groups. The focus is on the Chinese-origin elders, and the objective is to demonstrate their diverse migrant histories, cultural backgrounds and attitudes to both ‘traditional’ and Western health-care practices. The underlying argument is that if National Health Service staff had a better understanding of the diversity of Chinese older people, this would make an important contribution to making the service more sensitive to their needs. To develop this argument, this paper carries out three main analytical tasks. The first is to discuss the range of strategies adopted by Chinese people in general and Chinese older people in particular to improve their health. The second is to study Chinese people's heritage of exploring different methods to organise health in response to foreign culture. The third considers the ways in which the sensitivity of British health-care services to the needs of ethnic-minority groups can be improved, with a focus on the culturagram instrument and procedure. Three contrasting examples are presented.
How health affects retirement decisions: three pathways taken by middle-older aged New Zealanders
Authors: POND RACHAEL , STEPHENS CHRISTINE , ALPASS FIONA 
Published: December 2009

ABSTRACTConcerns about the economic impact of an ageing population have triggered many developed countries to advance policies that attempt to extend working lives and discourage early retirement. There is considerable evidence of a relationship between poor health and early retirement, but some researchers have suggested that there is a ‘justification bias’ in claims that ill-health is the cause of retirement. This paper reports a longitudinal qualitative study that interviewed 60 New Zealanders aged between 55 and 70 years on two occasions, and analysed their explanations of health-related retirement decisions. Although the participants' explanations included poor health as an important reason for retirement, two additional health-related retirement pathways were identified: the ‘maximisation of life’, being decisions to retire whilst healthy to fulfil other life goals; and ‘health protection’, being decisions motivated by health protection and promotion. These health pathways interacted with other factors such as financial security. An elucidation of these motivations pays particular attention to the social and discursive context of explanations of retirement, and considers the three identified health-retirement pathways in relation to the sickness justification bias and current government policies to extend working lives.
That's not my Robert! Identity maintenance and other warrants in family members' claims about mistreatment in old-age care
Authors: HARNETT TOVE , JÖNSON HÅKAN 
Published: December 2009

ABSTRACTThis study has explored how family members of care recipients define and sustain claims of mistreatment in old-age care. Twenty-one informants were recruited from an association of relatives of care recipients in Sweden. Using argumentation analysis, four warrants about mistreatment were identified from the qualitative interview data: they referred to physical harm, psychological harm, social-care deficiencies and identity subversion. The first three categories are similar to those recognised in previous research on elder mistreatment, but the fourth, which is described in detail in the article, is less familiar: elder mistreatment as the violation of an older person's identity. The family members backed their claims about staff members' violation of a care recipient's persona or identity by using arguments that drew on their unique knowledge of the care recipient's appearance, daily routines and preferred activities. They also described their attempts to protect the dignity and identity of a care recipient, their fears of abuse, and actual cases of conflict and retribution by care staff. They consistently positioned themselves as guardians of identity through their claims of mistreatment. The study provides important knowledge about family members' moral view of elder mistreatment, which may enhance the understanding of conflicts between formal care providers and family members.
The effects of age on health problems that affect the capacity to work: an analysis of United Kingdom labour-force data
Authors: NUÑEZ IMANOL 
Published: December 2009

ABSTRACTThis study estimates the effect of increases in age on 16 health problems that affect paid work for men and women in the United Kingdom. The analysis is based on a sample of the United Kingdom household population from the Office for National Statistics Labour Force Survey of 2007. Using multinomial logit regressions, the results reveal considerable diversity in the relationships between age and the reported prevalence of health problems that affect work. In particular, problems with heart, blood and circulation, arms and hands, legs and feet were strongly related to age, while difficulties in seeing and hearing, skin conditions and allergies appeared not to be more prevalent among older workers than younger employees. Regarding gender differences, it was found that, in general, women's health-related ability to participate in work was less affected by age, but that they suffered particular problems with arms and hands, skin conditions, allergies and depression. Finally, the study analyses the non-linear effects of unit increases in age. Such analysis may usefully identify the ages (or inflection points) at which ageing intensifies its effects on occupational health. These findings point to the importance of intervention at the appropriate time, when preventive measures may avoid the exacerbation of the health problem.
Cross-linguistic syntactic priming in bilingual children

Published: December 2009

ABSTRACTPrevious research has used cross-linguistic priming methodology with bilingual adults to explore the nature of their syntactic representations. The present paper extends the use of this methodology to bilingual children to investigate the relation between the syntactic structures of their two languages. Specifically, we examined whether the use of passives by the experimenter in one language primed the subsequent use of passives by the child in the other language. Results showed evidence of syntactic priming from Spanish to English: hearing a Spanish sentence containing a passive led to the increase in children's production of the parallel structure in English. However, there was no priming in the other direction: hearing an English sentence containing a passive did not increase children's use of the parallel structure in Spanish. These results provide evidence for both the integration of syntactic representations in bilingual children and the asymmetry of the relation between their two languages.
Quantity and significance of wild meat off-take by a rural community in the Eastern Cape, South Africa
Authors: KASCHULA SARAH A. , SHACKLETON CHARLIE M. 
Published: December 2009

SUMMARYWhen compared to tropical forest zones in west and central Africa, off-take of wild meat from savannah and grassland biomes by local rural communities has not been well assessed. This case study of wild meat collection activities within a rural community in the Mount Frere region of the Eastern Cape (South Africa) uses last-catch records derived from 50 wild meat gatherers to calculate average off-take of taxa, species and fresh mass of wild meat per collection event. When per-event off take is overlaid onto household hunting frequency data, annual off-take would be 268.6 kg km−2yr−1or 3 kg person−1yr−1presuming constant off-take over an annual period. Monetary value of off-take would be South African R 307 (US$ 39) per household annually. For some species, off-take weight per km2shows similar values to data from tropical forest zones, but high human population densities tend to dilute off-takes to less nutritionally significant amounts at the per person scale. However, unlike many tropical zones, none of the species harvested can be considered high-priority conservation species. Even densely populated and heavily harvested communal lands appear to offer high wild meat off-takes from low conservation priority species.
Variation in the host ABO blood group may be associated with susceptibility to hepatitis C virus infection

Published: December 2009

SUMMARYThis study aimed to determine the relationship between hepatitis C virus (HCV) infection and ABO/Rhesus blood groups, age and sex. A total of 20 000 patients who came to donate blood in the blood bank of GSVM Medical College, Kanpur were enrolled in the study. Demographic data recorded for each patient included age, sex and blood group. Blood samples were tested for anti-HCV antibodies and ABO/Rhesus blood group antigen typing was performed. The overall positive rate of anti-HCV was 0·34%. We found that seropositivity for HCV increased with age. Anti-HCV antibodies were detected in 1/765 women (0·13%), compared to 67/19 235 men (0·35%). Seroprevalence of HCV was found to be higher in blood group O individuals (0·42%) and lowest in blood group AB individuals (0·04%). The results of this study demonstrate that that HCV infection may not be related to age and sex but the possible association of blood group antigens with HCV infection cannot be ruled out.

Published: December 2009

SUMMARYIn Uganda, limiting the extent of foot-and-mouth disease (FMD) spread during outbreaks involves short-term measures such as ring vaccination and restrictions of the movement of livestock and their products to and from the affected areas. In this study, the presence of FMD virus RNA was investigated in cattle samples 3 months after FMD quarantine measures had been lifted following an outbreak in 2004. Oropharyngeal tissue samples were obtained from 12 cattle slaughtered in a small town abattoir in Kiboga. FMD virus RNA was detected by diagnostic RT–PCR in nine of the 12 tissue samples. Part of the coding region for the capsid protein VP1 was amplified and sequenced. All samples were identified as belonging to the SAT 2 serotype. The implications for FMD control of both virus introduction into Uganda and the presence of carrier animals following outbreaks are discussed.
Long-range migration of a chinstrap penguin from Bouvetøya to Montagu Island, South Sandwich Islands

AbstractWe describe a long-range migration of a pre-moulting adult chinstrap penguin from Bouvetøya, a small relatively recently established colony, to the South Sandwich Islands, where large, established colonies of this species reside. The trip lasted around three weeks, covered ∼3600 km, and the time of arrival was consistent with the annual moult. The bird did not travel along the shortest path or along a constant bearing, but instead followed what appeared to be a series of two or three rhumb lines of constant bearing. Small southward and northward deviations from the general path were consistent with local water currents. Travel speeds were high during daylight but decreased at night, suggesting that resting or opportunistic feeding occurred preferentially at night. While long-range winter migrations of chinstraps to feeding areas in the vicinity of distant colonies have been previously described, this is the first observation of such a trip during the period between breeding and moulting, and the first record of an individual actually arriving at one of these distant colonies. This has implications for understanding population structure and management of this important Southern Ocean predator.
North American population estimates of waterbirds, vultures and hawks from migration counts in Veracruz, México

Published: December 2009

SummaryContinental-scale bird population estimates are used as a decision-support tool in conservation plans. The calculation of these estimates includes the use of density values and survey data from one or multiple sources extrapolated to the geographic scale of interest. In this paper, we use migration count data from a migration monitoring project in Veracruz, Mexico, to revise existing North American population estimates of seven species of waterbirds, New World vultures, and diurnal raptors. In two species of waterbirds, we suggest that existing estimates are low and propose a mechanism to correct these figures. In the remaining five cases, we also determine present estimates are low, but use our data to provide new continental-scale values. We discuss the importance of refining population estimates using data from a diverse suite of field methods as a means to overcome the limitations of the single-survey-based estimates.
Dairy consumption and circulating levels of inflammatory markers among Iranian women
Authors: Esmaillzadeh Ahmad , Azadbakht Leila 
Published: December 2009

AbstractObjectiveAlthough recent studies have shown an inverse relationship between dairy consumption and metabolic abnormalities, we are aware of no study evaluating the association between dairy consumption and circulating levels of inflammatory markers. The current study was undertaken to assess the association between the consumption of high-fat and low-fat dairy products and circulating levels of inflammatory markers among Tehrani women aged 40–60 years.DesignIn a cross-sectional study of 486 apparently healthy women aged 40–60 years, we assessed usual dietary intakes by means of an FFQ. Anthropometric measurements were made and fasting blood samples were taken for measuring inflammatory markers.ResultsThe reported mean (sd) daily intake of low- and high-fat dairy consumption was 85 (sd 23) and 101 (sd 29) g/d, respectively. After control for age, BMI, waist circumference and other potential confounders, low-fat dairy consumption was inversely associated with C-reactive protein (β = −0.04), IL-6 (β = −0.02) and soluble vascular cell adhesion molecule-1 (β = −0.06); with further adjustment for dietary intakes, the associations remained significant just for soluble vascular cell adhesion molecule-1 (β = −0.03). High-fat dairy intake was positively associated with log-transformed values of serum amyloid A (β = 0.08) and soluble vascular cell adhesion molecule-1 (β = 0.05), both before and after adjustment for all potential confounding variables. No overall significant associations were found between total dairy consumption and inflammation.ConclusionsThe current study indicates an independent relationship between high-fat as well as low-fat dairy consumption, not total dairy intake, and some markers of inflammation and endothelial dysfunction. Further studies are required to identify responsible components of dairy products and related mechanisms of action.
REES MATRIX CONSTRUCTIONS FOR CLUSTERING OF DATA
Authors: KELAREV A. V. , WATTERS P. , YEARWOOD J. L. 
Published: December 2009

AbstractThis paper continues the investigation of semigroup constructions motivated by applications in data mining. We give a complete description of the error-correcting capabilities of a large family of clusterers based on Rees matrix semigroups well known in semigroup theory. This result strengthens and complements previous formulas recently obtained in the literature. Examples show that our theorems do not generalize to other classes of semigroups.
Bovine respiratory disease research (1983–2009)
Authors: Fulton Robert W. 
Published: December 2009

AbstractBovine respiratory disease (BRD) research has provided significant understanding of the disease over the past 26 years. Modern research tools that have been used include monoclonal antibodies, genomics, polymerase chain reaction, immunohistochemistry (IHC), DNA vaccines and viral vectors coding for immunogens. Emerging/reemerging viruses and new antigenic strains of viruses and bacteria have been identified. Methods of detection and the role for cattle persistently infected bovine viral diarrhea virus (BVDV) were identified; viral subunits, cellular components and bacterial products have been characterized. Product advances have included vaccines for bovine respiratory syncytial virus,Mannheimia haemolyticaandPasteurella multocida; the addition of BVDV2 to the existing vaccines and new antibiotics. The role ofMycoplasmaspp., particularlyMycoplasma bovisin BRD, has been more extensively studied. Bovine immunology research has provided more specific information on immune responses, T cell subsets and cytokines. The molecular and genetic basis for viral–bacterial synergy in BRD has been described. Attempts have been made to document how prevention of BRD by proper vaccination and management prior to exposure to infectious agents can minimize disease and serve as economic incentives for certified health programs.
Growth of microorganisms in Martian-like shallow subsurface conditions: laboratory modelling

Published: December 2009

AbstractLow atmospheric pressures on Mars and the lack of substantial amounts of liquid water were suggested to be among the major limiting factors for the potential Martian biosphere. However, large amounts of ice were detected in the relatively shallow subsurface layers of Mars by the Odyssey Mission and when ice sublimates the water vapour can diffuse through the porous surface layer of the soil. Here we studied the possibility for the active growth of microorganisms in such a vapour diffusion layer. Our results showed the possibility of metabolism and the reproduction of non-extremophile terrestrial microorganisms (Vibrio sp.) under very low (0.01–0.1 mbar) atmospheric pressures in a Martian-like shallow subsurface regolith.
