Comparative StudyEffects of various flow types on maternal hemodynamics during fetal bypass: is there nitric oxide release during pulsatile perfusion?
This study investigates the role of various flow conditions on maternal hemodynamics during fetal cardiopulmonary bypass. ⋯ Maternal hemodynamic changes observed under fetal pulsatile flow are counteracted after infusion of Nomega-nitro-L-arginine, suggesting nitric oxide release from the fetoplacental unit under pulsatile fetal flow conditions.

Prognostic assessment of 1310 patients with non-small-cell lung cancer who underwent complete resection from 1980 to 1993.
The TNM staging system of lung cancer is widely used as a guide for estimating prognosis and selecting treatment modality. In 1997, the International Union Against Cancer and the American Joint Committee on Cancer have adopted a revised stage grouping for lung cancer. However, the validity of the new stage grouping has not been fully established. We investigated the prognoses of patients who had resection of non-small-cell lung cancer to confirm the validity of the revised classification. ⋯ We supported most of the revision, such as dividing stage I, dividing stage II, and putting T3 N0 M0 to stage IIB. Furthermore, we found some candidates for a subsequent revision, such as putting T3 N1 M0 to stage IIB, putting T2 N0 M0 and T1 N1 M0 together, regarding diaphragm invasion as T4, and putting T3 N2 M0 to stage IIIB.
