 | Many promising strategies in experimental models of hemorrhage have failed in clinical trials, in part because classical experimental models may not mimic clinical settings. Unlike classical experimental models, hemorrhage in critical care is normally associated with collateral trauma that affects the physiological responses during resuscitation. Unlike rodents, swine are an optimal species donor for experimental hemorrhage as they have an anatomy, physiology and hemodynamic responses that closely resembles human. Here, ... |

A. Voss; M. Baumert; UNIVERSITY OF APPLIED SCIENCES JENA (GERMANY) FACULTY OF MEDICAL ENGINEERING
|
| The dilated cardiomyopathy (DCM) induces important changes in the autonomic control. Measures of heart rate (HR) variability and systolic blood pressure (SP) variability are sensitive to those changes. The interactions between HR and SP are rather complex and strongly non-linear. We introduced the joint symbolic dynamics (JSD) as a new short-term high resolution non-linear analysis method to investigate the complex interactions between HR and SP. Continuous non-invasive 30 minutes blood ... |

Matthew T. Andrews; NORTH CAROLINA STATE UNIV AT RALEIGH DEPT OF GENETICS
|
| During hibernation, mammals rely heavily on lipid stores to provide the fuel necessary to survive the winter. Pyruvate dehydrogenase kinase isozyme 4 (PDK4) plays a key role in gating carbohydrate catabolism and allowing the switch to lipid metabolism. Earlier we reported that PDK-4 was up- regulated in the heart of the thirteen-lined ground squirrel during hibernation. PDK-4 is encoded by the nuclear genome and acts by phosphorylating pyruvate dehydrogenase (PDH) ... |

|
| Patients undergoing hypothermic cardiopulmonary bypass are often on aspirin therapy. Hypothermia, aspirin, and cardiopulmonary bypass can each induce a platelet function defect, but it is not known if the effects of aspirin and hypothermia are additive in this regard. To address this question in humans in vivo, the forearm skin temperature of healthy volunteers was equilibrated and maintained at either normothermia (32 deg C) or hypothermia (28 ... |

|
| Heparin, a polyanionic glycosaminoglycan, is used routinely prior to the induction of cardiopulmonary bypass. Earlier observations in our laboratory suggested that the postoperative bleeding which occurs, despite neutralization of heparin with protamine, is secondary to hypothermia and dilutional anemia during bypass. An additional, potential mechanism for excessive bleeding following cardiopulmonary bypass is that heparin activates the fibrinolytic system, which may, in turn, adversely affect ... |
