Neuroprotection by ketamine
The fundamental clinical obstacle to the use of ketamine for neuroprotection is the historical textbook dogma that ketamine is contraindicated in patients at risk of increases in intracranial pressure (ICP) [1...

Studies on Tumor Oxygenation in a Rat Rhabdomyo-Sarcoma during Fractionated Irradiation
The oxygenation status of a tumor is certainly one of the major factors which influences the response of a tumor to radiotherapy (7, 9, 16, 22). Due to a chaotic and temporarily fluctuating tumor blood perfusi...

Influences of Various Respiratory and Circulatory Conditions on Muscle Tissue Oxygenation in Critically Ill Patients
Inadequate tissue perfusion results in inadequate oxygen transport to the mitochondria. The function of the circulatory systems is to guarantee an adequate cellular oxygen delivery to replace the oxygen used a...
