Late stage (III and IV) non-small cell cancer of the lung: results of surgical resection at Inova Fairfax Hospital.

One hundred forty-two patients underwent surgery and related treatment for advanced stage (III, IV) non-small cell cancer of the lung. One hundred seventeen patients underwent up-front surgery, with a hospital mortality rate of 1.7% (2/117).

Anabolic influences of insulin-like growth factor I and/or growth hormone on the diaphragm of young rats.

It is controversial whether insulin-like growth factor I (IGF-I), growth hormone (GH), or their combination might enhance body growth and/or tissue anabolism in the well-fed animal with an intact somatotrophic axis. To assess this further, we studied four groups of adolescent rats: 1) control (Ctr), 2) GH, 3) IGF-I, and 4) GH/IGF-I. IGF-I was given via an osmotic minipump, whereas GH was injected subcutaneously for a period of 72 h.

Effect of insulin-like growth factor I and/or growth hormone on diaphragm of malnourished adolescent rats.

Young growing animals appear to have significantly reduced "nutritional to short periods of unstressed starvation compared with adults, with resultant growth arrest and/or atrophy of diaphragm (Dia) muscle fibers. The aim of this study was to assess in an adolescent rat model of acute nutritional deprivation (ND; 72 h) the impact of insulin-like growth factor I (IGF-I), with or without added growth hormone (GH), on the cross-sectional areas (CSA) of individual Dia muscle fibers. Five groups were studied: 1) control (Ctr); 2) ND; 3) ND given IGF-I (ND/IGF-I); 4) ND given GH (ND/GH); and 5) ND given a combination of IGF-I and GH (ND/IGF-I/GH).

Interactive effects of denervation and malnutrition on diaphragm structure and function.

The purpose of this study was to examine the interactive effects of unilateral denervation (DN) and prolonged malnutrition (MN) on the structure and function of the diaphragm muscle (Dia). Four groups of rats were studied: control (Con), MN, DN, and DN-MN. MN began 2 wk after DN and lasted 4 wk.
