To examine preoperative dietary influences on gut-associated lymphoid tissue (GALT) cell number in the context of postoperative infectious complications. ⋯ Lack of enteral delivery of nutrients reduces numbers of T and IgA-producing cells, as well as mature DCs, in GALT of colon cancer patients, as it does in animal models. A close association between GALT changes and infectious complication morbidity was confirmed.

The education, training, and specialization of surgeons: turn-of-the-century America and its postgraduate medical schools.
To understand the institutions, personnel, and events that shaped postgraduate medical schools in late 19th- and early 20th-century America. ⋯ Postgraduate medical schools, particularly the New York Polyclinic and the New York Post-Graduate, were dominant influences in shaping the early history of surgery in America. These institutions brought the pressure for specialization in surgery to the forefront of discussions about medical education and training. For the first time, a large number of practitioners were offered a formalized surgical experience in a busy urban medical facility. As a result, and despite their being long forgotten, the importance of postgraduate medical schools in our nation's surgical history cannot be overstated.

Diabetes is known to increase poly-ADP-ribose-polymerase (PARP) activity and posttranslational poly-ADP-ribosylation of several regulatory proteins involved in inflammation and energy metabolism. These experiments test the hypothesis that PARP inhibition will modulate hind limb ischemia reperfusion (IR) in a mouse model of type-II diabetes and ameliorate the ribosylation and the activity/transnuclear localization of the key glycolytic enzyme glyceraldehyde-3-phosphate dehydrogenase (GAPDH). ⋯ PJ34 reduced PARP activity, GAPDH ribosylation, and GAPDH translocation; ameliorated muscle fiber injury; and increased metabolic activity after hind limb IR injury in a murine model of type-II diabetes. PARP inhibition might be a therapeutic strategy after IR in diabetic humans.
