Supplemental Watermelon Juice Attenuates Acute Hyperglycemia-Induced Macro-and Microvascular Dysfunction in Healthy Adults

Background Acute hyperglycemia reduces NO bioavailability and causes macro- and microvascular dysfunction. Watermelon juice (WMJ) is a natural source of the amino acid citrulline, which is metabolized to form arginine for the NO cycle and may improve …

Detection of the adulteration of extra virgin olive oil by near-infrared spectroscopy and chemometric techniques

Due to the value of extra virgin olive oil (EVOO), adulteration has become an important issue in the industry, which has created demand for quick and inexpensive fraud detection testing. In contrast to many current food fraud detection methods, …

Measuring prefrontal cortical activity during dual task walking in patients with Parkinson's disease: Feasibility of using a new portable fNIRS device

Background: Many patients with Parkinson's disease (PD) have difficulties in performing a second task during walking (i.e., dual task walking). Functional near-infrared spectroscopy (fNIRS) is a promising approach to study the presumed contribution …

Diagnosis of testicular torsion using near infrared spectroscopy: A novel diagnostic approach

We report a case of testicular torsion in a 14-month old boy. Testicular ischemia was suspected based on history and clinical presentations. The patient was referred following 24 hours of left acute scrotum. Erythema, swelling and tenderness …

Lateral frontal cortex oxygenation changes during translation and language switching revealed by non-invasive near-infrared multi-point measurements

The organisation of language in the brain of multilingual people remains controversial. Using a high temporal resolution 12-channel near-infrared continuous wave spectroscopy system, we have demonstrated that it is possible to monitor non-invasively, …

Cerebral oxygenation declines in healthy elderly subjects in response to assuming the upright position

Background and Purpose - With increasing age, assuming the upright position is more often accompanied by symptoms such as dizziness and lightheadedness, possibly as a result of a diminished oxygen supply to the brain due to impaired cerebral …

Near Infrared Spectroscopy: Toy or Tool?

A short history of oximetry During the second half of the 19th century it was discovered that blood cells contain a colouring substance whose spectrum is influenced by various blood gases [Hoppe, 1862]. Stokes discovered that this coloured substance …
