pH value monitoring during human albumin purification with near infrared spectroscopy and chemometrics

Novel Application of Near-infrared Spectroscopy and Chemometrics Approach for Detection of Lime Juice Adulteration

The aim of this study is to investigate the novel application of a ‎handheld near infra-red spectrophotometer coupled with classification methodologies as a screening approach in detection of adulterated lime juices. For this purpose, a miniaturized near infra-red spectrophotometer (Tellspec®) in the spectral range of 900–1700 nm was used. Three diffuse reflectance spectra of 31 pure...

Near infrared spectroscopy monitoring during carotid endarterectomy in elderly patients

Materials and methods 193, consecutive patients, 101 males, mean age 72 years, underwent CEA in our Institution from September 2007 to December 2009. All operations were only performed by two surgeons and all patients were monitored with TCO during general anesthesia. TCO parameters were always registered in: base-line, anesthesia induction, carotid clamping and declamping, wake up and estubati...

Near infrared spectroscopy monitoring during carotid endarterectomy: which threshold value is critical?

OBJECTIVES Retrospectively to verify which decreasing percentage in regional oxygen saturation (rSO(2)) identified patients with good collateralisation during carotid artery cross clamp. MATERIALS AND METHODS During 594 endarterectomies under general anaesthesia the decreasing percentage from preclamp value to value detected in the first 2 min after clamping the CCA and/or ICA was calculated ...
