Seal echolocation? (reply)

Echolocation

in their length can quantitatively explain the dynamic range of all helical and non-helical cell geometries. The purified, detergent insoluble cytoskeleton complex from spiroplasmas contains over ten proteins, the main one being a 59 kDa product of the fib gene with no known prokaryotic or eukaryotic homologs. Infectivity in spiroplasmas is governed by an unusual lipoprotein, spiralin, which co...

Apical seal versus coronal seal

the results of the initial study. It was concluded that the apical fluids, with their primary source being blood serum, diffuse into the empty canal spaces, stagnate, undergo degradation and then act as a physicochemical irritant when they diffuse back into periapical tissues. In support of this theory of stagnation, in 1955 Dow and Ingle showed that the majority of the endodontic failures were...

Reply re: "the efficacy of a midfacial seal drape in reducing oculofacial surgical field fire risk".

PURPOSE To evaluate the efficacy of a midface seal drape in eliminating fire risk oxygen concentrations from nasal cannulated oxygen delivery compared with a standard open oculofacial surgical field. METHODS Controlled experiment using the SimMan patient simulator and an oxygen detector. Oxygen concentrations were measured at 9 facial surgical locations with nasal cannula flow rates of 2, 4, ...
