Cerebral blood flow (CBF) is vital for delivering oxygen and nutrients to the brain. Many forms of orthostatic intolerance (OI) involve impaired regulation of CBF in the upright posture, which results ...

When using tracer-based techniques like arterial spin labeling (ASL) to quantify cerebral blood flow (CBF), it is necessary to determine the partition coefficient of the tracer between the perfused ...

Here, we highlight the complex molecular signaling that takes place in neurons, glial cells and the blood-brain barrier ... that take place every stage of cerebral ischemic injury, thus making ...

‘Wave analysis’ refers to a group of techniques that provide valuable insight into these interactions by scrutinizing the shape of blood pressure and flow/velocity waveforms. The aim of this review ...

They can be associated with arrhythmias, blood clots, and heart failure. The right atrium has a function in both the flow of blood through the heart, as well as in the heart's electrical system. In ...

The Price to Earnings (P/E) ratio, a key valuation measure, is calculated by dividing the stock's most recent closing price by the sum of the diluted earnings per share from continuing operations ...

Available laboratory tests may help diagnose lung cancer, though this is more likely with advanced tumors. Research offers hope that blood tests (biomarkers) will assist in the diagnosis or even ...

Cerebral oximeters obtain continuous, noninvasive cerebral oxygenation values [36] using near-infrared spectroscopy (NIRS) technology. A cerebral oximeter setup consists of an oximeter probe ...

Background Although flow diverters (FDs) have benefited from several technical improvements, recently concerns have arisen regarding the braid stability after implantation. Thus, we investigated ...
