TL;DR: A new planar multielectrode array (the MED probe) and its electronics which perform electrophysiological studies on acute hippocampal slices and a spatial distribution of long-term potentiation was studied using the MED system.

TL;DR: The success of these studies provides a novel proof-of-principle demonstration of lung tumor diagnosis through urinary volatile odorants, and should provide an impetus for similar searches for volatile diagnostic biomarkers in the urine of human lung cancer patients.

TL;DR: This study investigated to determine whether biomarkers derived from urinary volatile organic compounds (VOCs) can be used to discriminate between lung cancer patients and normal control patients and found that 2-pentanone may have utility in differentiating between adenocarcinoma and squamous cell carcinomas.

TL;DR: Both sample types produce distinct biomarker profiles, and VOCs have potential to distinguish between true- and false-positive screens for lung cancer.

TL;DR: An extracellular potential measuring device capable of simply and highly reliably detecting a change in a minute electrical signal emitted by a biological sample, and an Extracellular Potential Measurement Device (EPM) using the device and an apparatus comprising the device, are provided in this article.
