Acetazolamide (ACZ) was used to stimulate the cerebral vasculature on ten healthy volunteers to assess the cerebral vasomotor reactivity (CVR). We have combined near infrared spectroscopy (NIRS), diffuse correlation spectroscopy (DCS) and transcranial Doppler (TCD) technologies to non-invasively assess CVR in real-time by measuring oxy- and deoxy-hemoglobin concentrations, using NIRS, local cer...

Cerebral near-infrared spectroscopy (NIRS) has long represented an exciting prospect for the noninvasive monitoring of cerebral tissue oxygenation and perfusion in the context of traumatic brain injury (TBI), although uncertainty still exists regarding the reliability of this technology specifically within this field. We have undertaken a review of the existing literature relating to the applic...

Penentuan karakteristik dan konsentrasi unsur hara tanah perlu dilakukan metode analisa untuk perlakuan lahan serta ketepatan dosis jenis pemupukan dalam optimalisasi produktivitas tanaman. Metode alternatif analisis kandungan sampel secara cepat, efektif, ramah lingkungan, tidak merusak dapat menggunakan near infrared spectroscopy (NIRS). Sampel yang digunakan berasal dari Laboratorium Tanah, ...

Interferometric near-infrared spectroscopy (iNIRS) is a new technique that measures time-of-flight- (TOF-) resolved autocorrelations in turbid media, enabling simultaneous estimation of optical and dynamical properties. Here, we demonstrate reflectance-mode iNIRS for noninvasive monitoring of a mouse brain in vivo. A method for more precise quantification with less static interference from supe...

Near infrared reflectance spectroscopy (NIRS) provides an opportunity to measure cowspecific organic matter digestibility (OMD) from fecal samples. In this study individual digestibility measurements from a trial with 47 cows were investigated. Digestibility increased when lactation progressed. The repeatability estimates between different lactation stages were low which suggests that several f...
