Pseudoaneurysm is a rare but well-known complication of accidental or iatrogenic trauma. The large majority of those that appear on the head arise from the superficial temporal artery or its branches, although aneurysms arising from the nasal or angular arteries have also been described. We present the case of a man who was seen in our department for a rapidly growing, soft, pulsatile nodule in...

This paper describes experiments designed to evaluate Na+ and C1transport in isolated proximal straight tubules from rabbit kidneys. When the perfusing solution was Krebs-Ringer buffer with 25 mM HCO8 (KRB) and the bath contained KRB plus 6 % albumin, net volume reabsorption (J,, nl min-' mm-') was -0.46 4 0.03 (SEM); V., the spontaneous transepithelial potential difference, was -1.13 + 0.05 mV...

Many information fusion tasks involve the processing of Gaussian mixtures with simple underlying shape, but many components. This paper addresses the problem of reducing the number of components, allowing for faster density processing. The proposed approach is based on identifying components irrelevant for the overall density’s shape by means of the curvature of the density’s surface. The key i...
