TL;DR: Improved the performance of the spectrophotometer is improved and new in vivo measurements carried out in 23 healthy volunteers undergoing glucose tolerance tests are described, encouraging the precision and accuracy of the non-invasive determinations.

TL;DR: By evaluation on 3 patients with cardiac infarct or sleep apnea syndrome, patients’ health condition such as body and excretion weight in the toilet and apnea and hypopnea during sleeping were successfully monitored, indicating that the system appears useful for monitoring the health condition during daily living.

TL;DR: The results show that the regression calibration model based on the support vector machines can provide a good regression for the 101 paired data, in which the BGLs ranged from 89.0–219 mg/dl (4.94–12.2 mmol/l).

TL;DR: A prototype endoscopic system for observing inner wall of aorta was developed and tested in vivo using swine, suggesting an availability of the present method as an assistive technology for the endovascular interventions in aorte.

TL;DR: In this article, a novel optical non-invasive in vivo blood glucose concentration (BGL) measurement technique, named Pulse Glucometry, was combined with a kernel method; support vector machines; and a calibration model using paired data of a family of DeltaODlambdas and the corresponding known BGLs was constructed with support vector machine regression instead of using calibration by a conventional partial least squares regression (PLS).
