... Hypoxia Intravital microscopy Microcirculation Surgical flap Neovascularization Vascular remodeling Critical ischemia and hypoxia can lead to consecutive functional loss, cell death and necrosis in surgical flaps. During the last years, a new approach to tackle critical ischemia has emerged...

...) against human tumor cells under conditions of in vitro hypoxia, with the following results, (a) The HeLa cells had been exposed to various concentrations of MMC or CQ for 2 h under normally aerated (about 20%) or hypoxic conditions (5.0 and 0%) and were maintained under normally aerated conditions for 3...

... by anaerobic metabolism based on endogenous stores of glycogen. It is suggested that the myocardial ischaemic defence, as worked out by nature herself, in the diving seal has important implications for the treatment of acute myocardial ischaemia in man. 22 4 2008 Seal Myocardium Heart Hypoxia...

...J.L. Vincent; J. Goldstein; M. Domb; H. Lignan Serotonin can induce pulmonary hypertension, hypoxia and bronchoconstriction, and ketanserin has been shown to reverse these effects on various experimental models of acute respiratory failure. In the present study, the hemodynamic and gasometric...

One of the most important problems in Ihe treatment of injuries caused by high velocity missiles is to find the borderline between viable...

...John H. Duff The commonly accepted sequence of low blood flow, tissue hypoxia, lacticacidosis and death does not apply to all patients dying from shock. The hyperdynamic circulation characteristic of severe sepsis is not likely due to peripheral arteriovenous shunts, since in skeletal muscle...

... and aprotinin instilled into the intestinal lumen reduced to some extent the mucosal damage. The obtained data support the view that hypoxia is the key factor in the pathogenesis of the mucosal lesions. However, epithelial and intraluminal enzymes are probably important contributing factors. 3 02 1976...

...O.D. Saugstad; G. Bø; T. Østrem; A.O. Aasen Tissue hypoxia was induced in one group of dogs by clamping of the endotracheal tube and in another group by artificial ventilation with a mixture of nitrogen and air. The hypoxanthine concentration of venous and arterial plasma increased significantly...

...M. Ljungdahl; I. Rasmussen; G. Ronquist; U. Haglund This study aimed to investigate tissue hypoxia on the cellular level in sepsis. Eighteen pigs weighing 18–27 kg were studied. Intramucosal-arterial PCO 2 gradient (PCO 2 -gap) and intramucosal pH (pH i ) were calculated using tonometry. A blind...

.... Subcutaneous, arterial and mixed venous oxygen tensions were closely correlated (r = 0.94). A minor significant increase in subcutaneous carbon dioxide tension was noted during hyperoxia (p < 0.05). A major increase (33%) was noted during the last step of hypoxia, when arterial and mixed venous carbon...
