INTRODUCTION: Squatting is an active posture test that can be used to assess baroreflex sensitivity. Indeed, the shift from squatting to standing imposes a major orthostatic stress leading to rapid and large changes in arterial blood pressure (BP) and heart rate (HR) allowing precise baroreflex assessment. MATERIAL AND METHODS: BP and HR can be continuously and non-invasively monitored with a Finapres device. RESULTS: The standing to squatting transition is accompanied by rises in BP, pulse pressure and cardiac output, mainly due to increased venous return, and by a secondary reduction in HR. Conversely, the squatting to standing transition is associated with an immediate drop in BP and both reflex tachycardia and vasoconstriction. This mirror changes in BP and HR, mimicking those observed with the classical pharmacological approach using vasopressor/vasodilating agents, allows the calculation of the so-called baroreflex gain. DISCUSSION: The present review describes the haemodynamic changes occurring in normal subjects during the shifts from standing to squatting and from squatting to standing and discusses the underlying cardiovascular and autonomic mechanisms. CONCLUSION: This careful analysis in healthy individuals should help in the understanding of disturbances that may be observed in patients with autonomic dysfunction, such as in diabetic patients with cardiovascular autonomic neuropathy.

We have previously shown that overexpression of the Na-Ca exchanger (NCX1), a protein responsible for Ca(2+) extrusion from cells, increases β-cell programmed cell death (apoptosis) and reduces β-cell proliferation. To further characterize the role of NCX1 in β-cells under in vivo conditions, we developed and characterized mice deficient for NCX1. RESEARCH DESIGN AND METHODS: Biologic and morphologic methods (Ca(2+) imaging, Ca(2+) uptake, glucose metabolism, insulin release, and point counting morphometry) were used to assess β-cell function in vitro. Blood glucose and insulin levels were measured to assess glucose metabolism and insulin sensitivity in vivo. Islets were transplanted under the kidney capsule to assess their performance to revert diabetes in alloxan-diabetic mice. RESULTS: Heterozygous inactivation of Ncx1 in mice induced an increase in glucose-induced insulin release, with a major enhancement of its first and second phase. This was paralleled by an increase in β-cell proliferation and mass. The mutation also increased β-cell insulin content, proinsulin immunostaining, glucose-induced Ca(2+) uptake, and β-cell resistance to hypoxia. In addition, Ncx1(+/-) islets showed a two- to four-times higher rate of diabetes cure than Ncx1(+/+) islets when transplanted into diabetic animals. CONCLUSIONS: Downregulation of the Na/Ca exchanger leads to an increase in β-cell function, proliferation, mass, and resistance to physiologic stress, namely to various changes in β-cell function that are opposite to the major abnormalities seen in type 2 diabetes. This provides a unique model for the prevention and treatment of β-cell dysfunction in type 2 diabetes and after islet transplantation. [less ▲]

During the All Taxa Biodiversity Inventory + Monitoring programme (ATBI+M) in the Mercantour and Alpi Marittime National Parks, our inventories of bryophytes identified 234 taxa (mosses and liverworts). This work completes the previous field campaigns, notably those of Jean-Pierre Hebrard (I MEP, Marseille) since 1965, and the ATBI bryophyte inventories in 2007. This number is based on four days of inventories in the central and peripheric territory of both National Parks, in four days in July and August 2010, together with previous data the 565 taxa known from the area still underestimate the number of species actually present. Our observations in 2010 added several new species for this area, including several rare and remarkable species such as Haplomitrium hookeri or species listed under the Habitats Directive as Buxbaumia viridis and Orthotrichum rogeri. Given the rarity of their habitats species from snow beds, large block boulders and high altitude wetlands are most remarkable. [less ▲]

Nous développons un modèle dans lequel les travailleurs peuvent avoir tendance à trop travailler quand ils sont jeunes, parce qu’ils ne peuvent ou ne veulent pas voir les conséquences que cela peut avoir sur leur santé et sur leur capacité à travailler longtemps. Pour les obliger à mieux répartir leurs efforts sur leur cycle de vie, une taxe sur les revenus du travail en début de vie et une subvention de l’épargne sont souhaitables. Si la subvention de l’épargne n’est pas disponible, la taxe optimale arbitre entre quatre considérations différentes. Nous étudions également la taxe optimale quand les individus diffèrent en productivité. [less ▲]

Vietnam locates in the Asia-the most active region, where gains the highest economic growth rate and highest milk consumption in the world. Vietnam also ranks the second among the highest milk productivity in the Asia and milk consumption is increasing rapidly. However, the dairy industry in Vietnam is currently able to meet only 22% of domestic demand; the remaining amount has been imported (VOV/VNA, 2008). In addition, raw milk price is very low while retail price is too high. It leads to low effective in the production of the whole chain. This paper is based on the value chain approach within both quantitative and qualitative methods to evaluate a typical fresh value chain in the North of Vietnam in (Moc Chau platation) in 2008 - 2010. The findings show that the dairy plant is the most powerful actor in the chain and it drives the whole chain while power of dairymen is very weak. The value added of the chain is distributed unequally among its actors in whom more benefitable for non-dairy cow producers. In particular, the value added in dairy cow stage would be much lower.

Regression is a commonly used technique for describing the relationship between a response variable and one or more explanatory variables. When the response variable is a categorical variable, usual regression based on ordinary least squares should be replaced by logistic regression. Binary logistic regression should be used to perform a regression on a dichotomous response. Nominal polytomous logistic regression applies to a categorical response variable that has more than two levels with a natural ordering. And ordinal polytomous logistic regression is used when the response is a categorical variable that has more than two levels with a natural ordering. This note gives an overview of these logistic regression methods and describes three models commonly used when performing ordinal logistic regression. These models are illustrated by an example related to oak decline in the Walloon Region (Belgium). [less ▲]

The study looked into the current scenario of food security in Rwanda. After analysing the national level institutional and food security scenarios by using available secondary data, the researchers used primary data that have been collected from a random sample of 200 households spreading over six sectors of the Huye district by using structured interview schedule, as well using a case study of a rice cooperative in Huye district. Focus group discussions with all stake holders concerned with food security at local level enriched the data that we collected by other means. The general conclusion that emerges from the study is that in order to attain the food security at local level in Rwanda lot more to be done. Among other things, strengthening existing local institutions like farmer cooperatives, improving agricultural production technology, diversifying household income sources for better access, and genuine integration of food security concerns in the district development plans. The researchers come out with certain policy recommendations that may make the local level food security more sustainable which includes, among others, the orientation of the households well into the new modes of agricultural production and planning of household income. The need for much more local level institutional support in many areas is highlighted. On the whole, the study addressed the concerns of food access among rural households in Rwanda, and also the much wanted institutional support being exposed. [less ▲]
