Pete Maravich's incredible heart

Postmortem examination of a former professional basketball player revealed an abnormal heart, most notably a single coronary artery. The literature on single coronary arteries is briefly reviewed, and the possible mechanism which caused the patient's condition is considered. This case is particularly unusual because of the patient's profession, which is so physically demanding.

Cheap Hawks, Cheap Doves, and the Pursuit of Strategy

The post-9/11 threats to American security require a complete revision of American national strategy. For too long, presidents have had to favor quick, cheap solutions to crises, unable to count on support from the “homebody” public for long, drawn-out conflicts. “Cheap hawks” among them have hoped that apocalyptic rhetoric will suffice when resources fall short; “cheap doves” hope that by ignoring the threat, it will go away. But with the war on terror, the revival of geopolitics, and ever-accelerating globalization, the U.S. tradition of bellicose rhetoric backed by underwhelming force is a recipe for failure. To effectively manage its threats, America needs a new catechism and to make sure its economic, energy, and military policies support this.     

Sensitivity of various study technics in blood stains

Quadratic pieces of fleece measuring 16 mm2 were soaked with 10 different blood-samples in the dilution steps of 1:1, 1:10, 1:100, 1:1000, respectively, and were tested in blood group typing and identification tests of forensic serology. The above spezified dilutions correspond with 5 microliters, 0.5 microliter, 0.05 microliter and 0.005 microliter of blood, respectively. The detection limit of the microspectrometric test for blood was the dilution 1:10, of the porphyrine test a dilution above 1:100, whereas the preliminary test for blood (peroxidase) succeeded always up to a dilution of 1:1000 and the species determination by the radial immunodiffusion test in agar gels succeeded in most cases op to a dilution of 1:1000. The detection limit of the anti-human globulin inhibition test was between the dilution steps 1:10 and 1:100 when non-titrated and undiluted anti-human globulin serum was used. Gc- and ABO-grouping were possible up to a dilution of 1:100 and were thus the most sensitive grouping systems. Phenotyping of the enzyme-systems and the Gm/Km-system usually required stains with considerably higher blood concentrations i.e. stains of undiluted blood.
