OBJECTIVE To assess the type and amount of tissue missing from the adult circumcised penis. MATERIALS AND METHODS The gross and histological features of the prepuces of 22 adults obtained at autopsy were assessed, primarily focusing on the inner or mucosal surface of the prepuce. RESULTS Skin and mucosa sufficient to cover the penile shaft was(More)
BACKGROUND Papillary muscles of the left ventricle are prone to ischemic damage but seldom rupture, perhaps because they are protected by transendocardial diffusion and thebesian sinusoids as well as by arteries. Sinusoids are primitive vessels that precede coronary arteries as nutrient suppliers to all parts of the embryonic heart. OBJECTIVES To(More)
Portions of aortas from normal and atherosclerotic rabbits and from human autopsy subjects were washed and separated into layers which were subjected to exhaustive proteolytic digestion. The digests were assayed for epsilon(gamma-glutamyl)lysine crosslinks by a two-stage high performance liquid chromatography (HPLC) procedure. Crosslink concentrations in(More)
Thekinetic of 99mTc-labeled pyrophosphate were compared with those of polyphosphate in ten patients in a combined study. Both agents cleared from the blood in a biexpoential fashion. The clearance half-time of Exponent I was the same for both and was shorter than the clearance half-time of Exponent ii. Urinary excretion of both agents was the same during(More)
BACKGROUND In a previous paper the authors suggested that the right atrial appendage is structured for retrograde sinusoidal blood flow to embryonic conducting tissue in the venous sinus portion of the right atrium. OBJECTIVE To test the hypothesis that the relationship among conducting, valvar and trabecular myocardium of the human heart is primarily for(More)
BACKGROUND The developmental anatomy of the right atrium, particularly the union between its sinus venarum (sinus) and atrial portions, has not been completely settled. Invagination of the embryonic sinus into the atrium brings about electrical and structural union between these primitive chambers but results in the formation of the terminal crest, a(More)
