Oxygen Consumption Rate of Human Intervertebral Disc Cells

INTRODUCTION The intervertebral disc (IVD) is the largest avascular structure in the human body, and is comprised of three major components: the annulus fibrosus (AF), nucleus pulposus (NP), and cartilaginous end-plate (CEP). Compromised disc nutrition is believed to be the key factor in the development of disc degeneration which has hampered previous tissue engineering or repair efforts. The b...

Oxygen consumption of the living human brain measured after a single inhalation of positron emitting oxygen.

We measured the rate of washout of 15O-labeled water generated from labeled oxygen accumulated in brain after bolus [15O]O2 inhalation, and compared the washout with that of labeled water measured with H215O. Contrary to the original expectation, the radioactive water generated from labeled oxygen failed to leave the brain tissue at the rate predicted by exogenous water. Therefore, the use of a...

Regional cerebral blood flow and oxygen consumption in human aging.

The oxygen-15 continuous inhalation technique and PET were used to study the age-related changes in regional CBF and CMRO2. Twenty-seven patients, aged 19 to 76 years, free of any history of cerebral disease and vascular risk factors were examined in "resting state." CBF, CMRO2 and oxygen extraction fraction (OEF) values were calculated in seven different brain structures as well as in mean gra...
