Sodium Aspartate as a Specific Enhancer of Salty Taste Perception—Sodium Aspartate Is a Possible Candidate to Decrease Excessive Intake of Dietary Salt

The excessive intake of dietary salt is a global issue in health. Attempts have been made to address this issue, including the development of salt substitutes. Yet, none of these substances are currently in wide use, because of their weak saltiness. The purpose of this study was to assess t ... more

Gray Matter Volume Reduction of Olfactory Cortices in Patients With Idiopathic Olfactory Loss

Using Sniffing Behavior to Differentiate True Negative from False Negative Responses in Trained Scent-Detection Dogs

False negatives are recorded in every chemical detection system, but when animals are used as a scent detector, some false negatives can arise as a result of a failure in the link between detection and the trained alert response, or a failure of the handler to identify the positive alert. A ... more

Sensitive impedimetric biosensor based on duplex–like DNA scaffolds and ordered mesoporous carbon nitride for silver(I) ion detection

This study demonstrates a new unlabeled immobilized DNA–based biosensor with ordered mesoporous carbon nitride material (MCN) for detection of Ag+ by electrochemical impedance spectroscopy (EIS) with [Fe(CN)6]4–/3– as redox couple. The unlabeled immobilized DNA initially formed the hairpin ... more

Sensitive marker bands for the detection of spin states of heme in surface-enhanced resonance Raman scattering spectra of metmyoglobin

Surface-enhanced resonance Raman scattering (SERRS) spectra of myoglobin (Mb) with various ligands were measured. In the resonance Raman scattering (RRS) spectra, the peaks around at 1610 and 1640 cm–1 have been used to discriminate between the heme iron in high or low spin state so far. In ... more

Propofol detection and quantification in human blood: the promise of feedback controlled, closed-loop anesthesia

The performance of a membrane-coated voltammetric sensor for propofol (2,6-diisopropylphenol) has been characterized in long term monitoring experiments using an automated flow analytical system (AFAS) and by analyzing human serum and whole blood samples by standard addition. It is shown th ... more

Microscale Anechoic Architecture: Acoustic Diffusers for Ultra Low Power Microparticle Separation via Traveling Surface Acoustic Waves

We present a versatile and very low-power traveling SAW microfluidic sorting device able to displace and separate particles of different diameter in aqueous suspension; the travelling wave propagates through the fluid bulk and diffuses via a Schröder diffuser, adopted from its typical use i ... more

Microfluidic pipette array for mechanophentyping of cancer cells and mechanical gating of mechanosensitive channels

Micropipette aspiration measures the mechanical properties of single cells. A traditional micropipette aspiration system requires a bulky infrastructure, and has a low throughput and limited potential for automation. We have developed a simple microfluidic device, which is able to trap and ... more

Evidence that Humans Can Taste Glucose Polymers

The sense of taste is essential for identifying potential nutrients and poisons. Accordingly, specialized taste receptor cells are activated by food-derived chemicals. Because of its importance in the human diet, oral detection of starch, or its degradation products, would presumably be hig ... more
