[Peripheral arterial disease in black African diabetics: epidemioclinical, ultrasonographic profile and determining factors].

Background: Diabetes can lead to micro and macro-angiopathies. The peripheral arterial disease (PAD) is a serious and an incapacitating disease. It is still under-estimated and under-treated throughout the world, particularly in sub-Saharan Africa.

[Management of heart failure at the CHU the National Reference of Ndjamena/Chad].

Introduction: Heart failure (HF) is a syndrome of diverse etiologies, and a real public health problem in both developed and developing countries. The aim of this study was to determine the clinical, etiological, therapeutic and evolutionary aspects of heart failure.

Materials And Methods: This was a descriptive and analytical study carried out in the cardiology department of the national referral university hospital in N'Djamena (Chad).

[Prevalence of dyslipidemia in the biochemistry laboratory of the Reference National Teaching Hospital of N'Djamena, Chad.].

Introduction: les dyslipidémies constituent un facteur de risque majeur dans la survenue des maladies cardio-vasculaires. La recherche de ce facteur et sa prise en charge adéquate contribuerait à prévenir ces maladies qui sont la plus grande cause de décès dans le monde. L'objectif de cette étude était d'évaluer la prévalence des dyslipidémies au laboratoire de biochimie du Centre Hospitalier Universitaire de Référence Nationale de N'Djamena.

Interactions within the climate-vegetation-fire nexus may transform 21st century boreal forests in northwestern Canada.

Dry and warm conditions have exacerbated the occurrence of large and severe wildfires over the past decade in Canada's Northwest Territories (NT). Although temperatures are expected to increase during the 21st century, we lack understanding of how the climate-vegetation-fire nexus might respond. We used a dynamic global vegetation model to project annual burn rates, as well as tree species composition and biomass in the NT during the 21st century using the IPCC's climate scenarios.

Atlantic SSTs control regime shifts in forest fire activity of Northern Scandinavia.

Understanding the drivers of the boreal forest fire activity is challenging due to the complexity of the interactions driving fire regimes. We analyzed drivers of forest fire activity in Northern Scandinavia (above 60 N) by combining modern and proxy data over the Holocene. The results suggest that the cold climate in northern Scandinavia was generally characterized by dry conditions favourable to periods of regionally increased fire activity.

Regional paleofire regimes affected by non-uniform climate, vegetation and human drivers.

Climate, vegetation and humans act on biomass burning at different spatial and temporal scales. In this study, we used a dense network of sedimentary charcoal records from eastern Canada to reconstruct regional biomass burning history over the last 7000 years at the scale of four potential vegetation types: open coniferous forest/tundra, boreal coniferous forest, boreal mixedwood forest and temperate forest. The biomass burning trajectories were compared with regional climate trends reconstructed from general circulation models, tree biomass reconstructed from pollen series, and human population densities.

Vegetation limits the impact of a warm climate on boreal wildfires.

Strategic introduction of less flammable broadleaf vegetation into landscapes was suggested as a management strategy for decreasing the risk of boreal wildfires projected under climatic change. However, the realization and strength of this offsetting effect in an actual environment remain to be demonstrated. Here we combined paleoecological data, global climate models and wildfire modelling to assess regional fire frequency (RegFF, i.

Control of the multimillennial wildfire size in boreal North America by spring climatic conditions.

Wildfire activity in North American boreal forests increased during the last decades of the 20th century, partly owing to ongoing human-caused climatic changes. How these changes affect regional fire regimes (annual area burned, seasonality, and number, size, and severity of fires) remains uncertain as data available to explore fire-climate-vegetation interactions have limited temporal depth. Here we present a Holocene reconstruction of fire regime, combining lacustrine charcoal analyses with past drought and fire-season length simulations to elucidate the mechanisms linking long-term fire regime and climatic changes.

A new, isolated and endangered relict population of dwarf pine (Pinus mugo Turra) in the northwestern Alps.

Dwarf pines were discovered in 2004 during a paleoecological survey in the Mont Cenis massif (Savoy, France). These dwarf pines are the sole natural and spontaneous population in the NW French Alps of Pinus mugo Turra, ssp. mughus (Scop.

Recent peat accumulation rates in minerotrophic peatlands of the Bay James region, Eastern Canada, inferred by 210Pb and 137Cs radiometric techniques.

(210)Pb and (137)Cs dating techniques are used to characterise recent peat accumulation rates of two minerotrophic peatlands located in the La Grande Rivière hydrological watershed, in the James Bay region (Canada). Several cores were collected during the summer 2005 in different parts of the two selected peatlands. These minerotrophic patterned peatlands are presently affected by erosion processes, expressed by progressive mechanical destruction of their pools borders.

[Fire and Pinus mugo Turra communities in the western Alps (Susa Valley, Italy) during the Lateglacial-Holocene transition: an evidence of refugia area].

In western Italian Alps, small distinct populations of Pinus mugo Turra raise some questions concerning its ecological status and dynamics in the occidental Alps. This note present new palaeobotanical data based on cone imprints of Pinus mugo, identified in travertine systems located in the Val di Susa and dated back to the Late Dryas (11506+/-66 BP) and the Early Holocene (10145+/-225 et 9475+/-670 BP). Heliophilous species and charcoal fragments were also identified, testifying to the oldness of wildfires in this region.

[Proof of the indigenous nature of Populus alba L. in the western Mediterranean Basin].

Around the western Mediterranean Basin, the ecological status of Populus alba, whether indigenous or introduced, is controversial. This note presents new palaeobotanical data based on analyses of leaf imprints from a travertine formation located in southern France. This travertine presents two levels with Populus alba imprints.
