Europe's terrestrial biosphere absorbs 7 to 12% of European anthropogenic CO2 emissions

Abstract: Most inverse atmospheric models report considerable uptake of carbon dioxide in Europe's terrestrial biosphere In contrast, carbon stocks in terrestrial ecosystems increase at a much smaller rate, with carbon gains in forests and grassland soils almost being offset by carbon losses from cropland and peat soils Accounting for non-carbon dioxide carbon transfers that are not detected by the atmospheric models and for carbon dioxide fluxes bypassing the ecosystem carbon stocks considerably reduces the gap between the small carbon-stock changes and the larger carbon dioxide uptake estimated by atmospheric models The remaining difference could be because of missing components in the stock-change approach, as well as the large uncertainty in both methods With the use of the corrected atmosphere- and land-based estimates as a dual constraint, we estimate a net carbon sink between 135 and 205 teragrams per year in Europe's terrestrial biosphere, the equivalent of 7 to 12% of the 1995 anthropogenic carbon emissions

Rey-Osterrieth complex figure: normative values in an Italian population sample

Abstract: The Rey-Osterrieth complex figure test (ROCF) is a neuropsychological test extensively used in clinical practice to investigate visuospatial constructional functions, visuographic memory and some aspects of planning and executive function. The aim of the present study was to collect normative values in an Italian normal population sample (n=280) for the direct copying and delayed (10 min) reproduction of the ROCF. Multiple regression analysis revealed significant effects of age and education on performance of both copying tasks, whereas sex appeared to affect only performance on the delayed copying task. Inferential cut-offs have been determined and equivalent scores computed. The availability of equivalent scores for the ROCF will prove useful in clinical assessment since it allows the comparison of a subject's performance on the ROCF with that on other neuropsychological tests for which normative values collected with similar methods are already available for the Italian population.

Rupture of the Achilles Tendon

Abstract: Achilles, the warrior and hero of Homer's Iliad, lends his name to the Achilles tendon, the thickest and strongest tendon in the human body138. Thetis, Achilles's mother, made him invulnerable to physical harm by immersing him in the river Styx after learning of a prophecy that Achilles would die in battle. However, the heel by which he was held remained untouched by the water and thus Achilles had a vulnerable point. Achilles led the Greek military forces, which captured and destroyed Troy after killing the Trojan prince Hector. However, Hector's brother Paris killed Achilles by firing a poisoned arrow into his heel164. Hippocrates, in the first recorded description of an injury to the Achilles tendon, stated that “this tendon, if bruised or cut, causes the most acute fevers, induces choking, deranges the mind and at length brings death.”26 Ambroise Pare, in 1575, recommended that a ruptured Achilles tendon be strapped with bandages dipped in wine and spices, but advised that the result was dubious27. Operative repair of a ruptured Achilles tendon was advocated in 1888 by another Frenchman, Gustave Polaillon27, although an Arabian physician performed such procedures as early as the tenth century A.D. In the twelfth century, an Italian surgeon, Guglielmo di Faliceto, believed that nature was unable to unite divided tendons and that operative treatment was necessary27. Much research has been performed to elucidate the etiology of a rupture of the Achilles tendon, but its true nature still remains unclear190. Also, the best method of treatment is still fiercely debated. Some physicians advocate operative repair, whereas others insist that an operation is unnecessary and poses an unacceptable risk. The tendinous portions of the gastrocnemius and soleus muscles merge to form the Achilles tendon. The plantaris …
