Insects Notably Injurious in Louisiana During 1908-1909

The discovery of Trypanosoma cruzi and Chagas disease (1908-1909): tropical medicine in Brazil.

This article analyzes the discovery of Chagas disease and the parasite that causes it (Trypanosoma cruzi) by Carlos Chagas in 1908/1909, with a special focus on the scientific and social context in which this occurred. Its inclusion in the international debate on European tropical medicine--especially with researchers from the German school of protozoology--and its connection with discussions o...

The discovery of chagas disease (1908-1909): great successes and certain misunderstandings and challenges.

Notably improved DMPS data inversion

Pulmonary impedance and alveolar instability during injurious ventilation in rats.

The mechanical derangements in the acutely injured lung have long been ascribed, in large part, to altered mechanical function at the alveolar level. This has not been directly demonstrated, however, so we investigated the issue in a rat model of overinflation injury. After thoracotomy, rats were mechanically ventilated with either 1) high tidal volume (Vt) or 2) low Vt with periodic deep infla...

Virginia Apgar (1909-1974)

Virginia Apgar worked as an obstetrical anesthesiologist, administering drugs that reduce women's pain during childbirth, in the mid-twentieth century US. In 1953, Apgar created a scoring system using five easily assessable measurements, including heart rate and breathing rate, to evaluate whether or not infants would benefit from medical attention immediately after birth. Apgar's system showed...
