Background Glioblastoma (GBM) is the most common and devastating malignant brain tumor in adults. Patients with glioblastoma face a poor prognosis. Despite maximal treatment, most patients suffer tumor progression after 6-7 months and die within 1-2 years. Standard treatment for newly diagnosed
Acute mountain sickness (AMS) is a constellation of symptoms including headache, sleep disturbance, fatigue, dizziness, and nausea, vomiting, or anorexia that commonly occurs in travelers ascending to altitudes above 2,500m. AMS incidence varies based on altitude and ascent profile with rates
The investigators know from previous studies that the level of inflammation in the blood is high after haemorrhagic stroke and want to investigate whether blocking this inflammation can improve outcomes. The only current treatments for haemorrhagic stroke are aimed at significantly reducing the
Acute mountain sickness (AMS) is a common ailment in people venturing over 2500 meters altitude. It is a pathological effect of high altitude on humans, caused by acute exposure to low partial pressure of oxygen at high altitude. It presents as a collection of nonspecific symptoms, acquired at high
Hepatocyte growth factor (HGF) is local acute phase protein with regenerative properties that become biologic inactive during chronic inflammation and loses the binding affinity to glycosaminoglycan in the extracellular ma-trix. HGF is excreted into the gastrointestinal tract and is not detected in
The exact mechanisms by which AMS develops remains poorly understood. Interestingly, brain and spinal cord swelling due to low oxygen levels can also occur in the period following surgery to treat thoracic and abdominal aortic aneurysms, dangerous swellings of the major blood vessel in the body.
The primary endpoint of this research study is to prove safety in healthy subjects breathing humidified hypoxic inspiratory gas mixture for 5 days.
The secondary endpoint of our study is to describe the physiological and biochemical changes during the 5-day hypoxic period and the 2 days after return
