Abstract:
Cama et al's review of pneumothorax management was excellent, especially their elegant depiction of chest tube diameter in comparison to the intercostal space, as measured in French gauge. The use of gauge is medicine is confusing due to differing systems and seemingly random increments. This diagram neatly shows that French gauge (Fr) is directly proportional to diameter, as the external diameter of the tube in millimetres is the gauge multiplied by three. For example, a 15 Fr chest tube has an external diameter of 5mm.

Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.
