Artificial neural networks based estimation of optical parameters by diffuse reflectance imaging under in vitro conditions [PDF]
Journal of Innovative Optical Health Sciences, 2017 Optical parameters (properties) of tissue-mimicking phantoms are determined through noninvasive optical imaging. Objective of this study is to decompose obtained diffuse reflectance into these optical properties such as absorption and scattering ...

Assessing the amount of the anatase and rutile phases of TiO2 by optical reflectance measurements
Results in Physics, 2021 The anatase (A) and rutile (R) phases of a series of titanium dioxide (TiO2) samples were investigated by optical diffuse reflectance spectroscopy. The samples consisted of commercial A and R high-purity TiO2 powders mixed together according to the Rmass/

FEBS Letters, EarlyView.Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Optical Properties of Living Corals Determined With Diffuse Reflectance Spectroscopy
Frontiers in Marine Science, 2019 The internal light field and thus light exposure of the photosymbiotic microalgae (Symbiodinium sp.) in corals is strongly modulated by the optical properties of coral tissue and skeleton.

Chiral separation of chloroalkanes with the chromatographic column onboard Martian rovers
FEBS Letters, EarlyView.Computer image of the Rosalind Franklin Rover of ESA's ExoMars mission. ExoMars is scheduled to land on planet Mars in Oxia Planum in 2029. This area represents an interesting spot to look for biosignatures. Investigations of ExoMars include measurement on molecular chirality. We show that chiral chloroalkanes, that have been identified on Mars, can be

Molecular Oncology, EarlyView.The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

Diffuse Reflectance Spectroscopy with Infrared Thermography for Accurate Prediction of Cellulitis
JID Innovations, 2021 Cellulitis is frequently misdiagnosed owing to its clinical mimickers, collectively known as pseudocellulitis. This study investigated diffuse reflectance spectroscopy (DRS) alone and in combination with infrared thermography (IRT) for the ...
