Chasse et dĂ©veloppement territorial. Vers un cadre dâanalyse global ?
Lâarticle propose une analyse de la contribution des activitĂ©s cynĂ©gĂ©tiques au dĂ©veloppement territorial en sâappuyant sur deux cadres thĂ©oriques complĂ©mentaires. Dâune part, une version revisitĂ©e de la thĂ©orie de la base intĂ©grant "une base de consommation" peut permettre de rendre compte des effets Ă la fois des chasseurs extĂ©rieurs et des chasseurs locaux. Dâautre part, la chasse peut ĂȘtre Ă lâorigine dâun processus dâinnovation et de spĂ©cification des ressources territoriales.The paper proposes an analysis of the contribution of huntings to local development with two complementary theoretical frameworks. On one hand, a revisited version of the economic base models integrating "a consumption base" is able to measure both effects of the external hunters and the local hunters. On the other hand, hunting can generate an innovation process and specification of "territorial resources"

Raman spectroscopy imaging reveals interplay between atherosclerosis and medial calcification in human aorta
Medial calcification in the human aorta accumulates during aging and is known to be aggravated in several diseases. Atherosclerosis, another major cause of cardiovascular calcification, shares some common aggravators. However, the mechanisms of cardiovascular calcification remain poorly understood. To elucidate the relationship between medial aortic calcification and atherosclerosis, we characterized the cross-sectional distributions of the predominant minerals in aortic tissue, apatite and whitlockite, and the associated extracellular matrix. We also compared the cellular changes between atherosclerotic and nonatherosclerotic human aortic tissues. This was achieved through the development of Raman spectroscopy imaging methods that adapted algorithms to distinguish between the major biomolecules present within these tissues. We present a relationship between apatite, cholesterol, and triglyceride in atherosclerosis, with the relative amount of all molecules concurrently increased in the atherosclerotic plaque. Further, the increase in apatite was disproportionately large in relation to whitlockite in the aortic media directly underlying a plaque, indicating that apatite is more pathologically significant in atherosclerosis-aggravated medial calcification. We also discovered a reduction of ÎČ-carotene in the whole aortic intima, including a plaque in atherosclerotic aortic tissues compared to nonatherosclerotic tissues. This unprecedented biomolecular characterization of the aortic tissue furthers our understanding of pathological and physiological cardiovascular calcification events in humans
