Background:
Osteosarcoma (OS) is the most common type of primary malignant bone tumor in children and adolescents. The overall survival rate is dramatically reduced by the development of metastases, often pulmonary. Solid malignant tumors, such as OS, often develop a hypoxic microenvironment, which
The dysfunction of wound healing in diabetes involves multiple healing processes by diminished inflammatory responses and delayed deposition of matrix components, wound remodeling, and closure. Furthermore, hyperglycemia increases the infection susceptibility of wounds. The wounds noted at distal
Raynaud's phenomenon (RP) is characterised by a recurrent transient vasospasm of the fingers or toes in response to a cold or stressful stimulus. Nitric oxide (NO•) is a known vasodilator and NO• donors, such as Glyceryl Trinitrate (GTN), improve blood flow in patients with RP and in cold sensitive
Specific Aims:
1A. Determine the independent contributions of NOS and COX to hypoxic and hypercapnic vasodilation in the MCA of young, healthy adults.
1B. Determine the combined contribution of NOS and COX to hypoxic and hypercapnic vasodilation in the MCA of young, healthy adults.
1. C. Determine
Citrulline is an amino-acid almost exclusively released by the small intestine after its synthesis from glutamine by the OTC in enterocytes. Citrulline from the small intestine is released into the portal vena and, because it does not enter hepatocytes, it reaches the systemic circulation to be
Neurological prognostication of patients in therapeutic hypothermia after cardiac arrest
Background: In Denmark, approximately 3000 people suffer from cardiac arrest (CA) each year. After CA with no blood flow for more than five minutes, cerebral ischemia, free radicals along with other mediators
Study aim A: Red cell mass and hypoxia:
Various forms of altitude training have been used to increase in particular endurance performance of elite athletes. The most commonly used approaches is either to live and train at altitude (Live high - train high; LHTH) or to live at high altitude while
The hypothesis of the study is the following: Patients with sleep apnea-hypopnea syndrome have higher risk of cardiovascular mortality during the night.
Respiratory alterations (hypoxia, hypoxia- reoxygenation) that these patients suffer during the sleep may induce modifications in platelet
Objective To study the effect of two preoperative immune enhancing nutritional supplements compared with a control nutritional supplement in 'high risk' risk cardiac surgery patients
Introduction: Elderly patients and patients with a poor ventricular function undergoing cardiac operations with
During exercise, there is a lag in the rate at which oxygen uptake (VO2) rises to meet energy demand. It is uncertain whether this limitation is due to inadequate O2 delivery to working muscle, limitations to the rate at which mitochondria can generate ATP to meet demand, or by a combination of
