[Christmas article: Christmas article: The professors take up the master's program at Rigshospitalet].

Caricatures highlight personal characteristics. The caricature drawing of the four prominent professors from the transition from the Royal Frederik's Hospital to Rigshospitalet, Copenhagen in 1910, shows the dominant surgeon Niels Thorkild Rovsing (1862-1927), who takes up half of the drawing; the reserved organizationally interested physician Knud Helge Faber (1862-1956) in the middle; the thoughtful surgeon Oscar Thorvald Bloch (1847-1926), and the somewhat isolated physician Hans Christian Joachim Gram (1853-1938), who became known for his staining method to separate Gram-positive from Gram-negative bacteria.

The Impact of Weight-bearing Exercise, Non-Weight-bearing Exercise, and Cardiovascular Stress on Biochemical Markers of Cartilage Turnover in Patients With Mild to Moderate Knee Osteoarthritis: A Sequential, Cross-Over, Clinical Study.

Objective: To investigate how running, cycling, and sedentary cardiovascular stress impact biomarkers of cartilage turnover acutely in subjects with knee osteoarthritis (OA).

Design: This was a sequential, cross-over, clinical study. Forty subjects with primary knee OA underwent moderate-to-high-intensity cycling, running, and adrenaline infusion on separate days.

The athlete's heart: allometric considerations on published papers and relation to cardiovascular variables.

To evaluate the morphology of the "athlete's heart", left ventricular (LV) wall thickness (WT) and end-diastolic internal diameter (LVIDd) at rest were addressed in publications on skiers, rowers, swimmers, cyclists, runners, weightlifters (n = 927), and untrained controls (n = 173) and related to the acute and maximal cardiovascular response to their respective disciplines. Dimensions of the heart at rest and functional variables established during the various sport disciplines were scaled to body weight for comparison among athletes independent of body mass. The two measures of LV were related (r = 0.

Stable mass-selected AuTiO nanoparticles for CO oxidation.

Stability under reactive conditions poses a common challenge for cluster- and nanoparticle-based catalysts. Since the catalytic properties of <5 nm gold nanoparticles were first uncovered, optimizing their stability at elevated temperatures for CO oxidation has been a central theme. Here we report direct observations of improved stability of AuTiO alloy nanoparticles for CO oxidation compared with pure Au nanoparticles on TiO.
