Reflectance spectra of terrestrial barites conducted in the Planetary Emissivity Laboratory (PEL)

, 2011
The most important source for barite on Earth is often associated to sedimentary exhalative sulfide deposits (SedEx) and volcanic environments generated by hydrothermal activity.

Theoretical investigation of measuring cerebral blood flow in the adult human head using bolus indocyanine green injection and near-infrared spectroscopy [PDF]

, 2007
To investigate the accuracy of measuring cerebral blood flow (CBF) using a bolus injection of indocyanine green (ICG) detected by near infrared spectroscopy in adult human heads, simulations were performed using a two layered model, representing the ...

Developmental and Epileptic Encephalopathy due to Biallelic Pathogenic Variants in PIGM

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective PIGM encodes a critical enzyme in the glycosylphosphatidylinositol (GPI)‐anchor biosynthesis pathway. While promoter‐region mutations in PIGM have been associated with a relatively mild phenotype characterized by portal vein thrombosis and absence seizures, recent evidence suggests that coding‐region mutations result in a more severe

Biocompatible materials based on synthetic apatites co-doped with silver and lutetium ions

Moldavian Journal of the Physical Sciences, 2009
Apatite based (CaHap and CaFap) materials were synthesized by saline–melt method at moderate temperature. Their structure and composition have been studied by X-ray phase analysis (XRPA) and IR spectroscopy of diffuse reflectance.

Spectroscopic analysis of Pu-bearing compounds in double-walled cells

Frontiers in Nuclear Engineering
Spectroscopic analysis of radiological materials has been historically limited to radiological labs with older or less advanced scientific instrumentation. The development of double-walled cells (DWCs) at the Savannah River National Laboratory (SRNL) has

CSF Monoamine Metabolites and Cognitive Trajectory in Early Parkinson's Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Imaging and postmortem studies indicate that abnormalities in monoaminergic neurotransmission contribute to cognitive impairment in Parkinson's disease (PD). However, it remains uncertain if cerebrospinal fluid (CSF) monoamine metabolites can serve as biomarkers of cognitive decline in early PD.

Elastic scattering spectroscopy accurately detects high grade dysplasia and cancer in Barrett's oesophagus

, 2006
Background and aims: Endoscopic surveillance of Barrett’s oesophagus currently relies on multiple random biopsies. This approach is time consuming, has a poor diagnostic yield, and significant interobserver variability. Elastic scattering spectroscopy is
