Summary: This study found that artificial saliva was perceived as aversive at both concentrations, while bottled water was rated as emotionally neutral; therefore, future gustatory studies should take caution when using artificial saliva as a neutral baseline and collect trial-by-trial ratings.

Summary: The objective of this study was to test gustatory function in the early days of COVID-19, and it found that 28% of the 51 patients had hypogeusia. This percentage is significantly lower than the patients' self-reports. Furthermore, there was no clear evidence of specific taste qualities impairment.

Summary: This study assessed the burn extent and depth in patients with burns using a custom-built 36-channel functional near-infrared spectroscopy system. Hemodynamic tissue signals measured during fNIRS showed significant differences between different burn categories, indicating that functional near-infrared spectroscopy can help with the early judgment of burn extent and depth by reflecting differences in the oxygen saturation levels in the skin.

Summary: Self-reported olfactory and gustatory dysfunction, as well as unvalidated and limited psychophysical tests, although showing high specificity and DOR values, were not sensitive enough in screening for COVID-19 and were not suitable adjuncts in ruling out the disease.

Summary: This study focuses on the contamination of optical signals in non-invasive optical measurements of the human brain caused by superficial hemodynamics. The authors identified optimal source-detector distances for dual-slope measurements in frequency-domain near-infrared spectroscopy (NIRS) and demonstrated the preferential sensitivity of dual-slope imaging to deeper tissue (brain) compared to superficial tissue (scalp). The results showed that the mean distance between the two source-detector distances is the key factor for depth sensitivity. Dual-slope imaging with frequency-domain NIRS may suppress confounding contributions from superficial hemodynamics and has significant implications for non-invasive optical measurements of the human brain.

Summary: The study evaluated the utility and reliability of near-infrared spectroscopy (NIRS) in measuring tibial hemodynamics and metabolic rate. The results showed that NIRS is a suitable tool for monitoring hemodynamics and metabolism in the tibia. Additionally, the local muscle exercise protocol utilized did not influence bone hemodynamics or metabolic rate, suggesting that high level of loading and exercise volume may be needed to elicit measurable metabolic changes in bone.

Summary: This study investigated the ability of NIRS to identify different concentrations of L-fucose and L-proline solutions, showing potential for detecting differences in biomarker concentrations in aqueous solutions. The qualitative measures may have limited sensitivity, but could be enhanced with additional samples and a specialized measurement probe for fluid measurements.

Summary: This study demonstrates the presence of nonlinearity in high frequency fNIRS signals due to blood flow autoregulation. Nonlinear representations quantified by sample entropy differentiate neural representations between different frequency bands. Additionally, independence of cortical activity between fast and slow waves is observed only in nonlinear analysis.

Summary: A top-down composition design strategy was proposed to develop hypersensitive X-ray-stimulated NIR-PLNPs LaGaO3:Sb3+,Cr3+ with enhanced NIR persistent luminescence performance, demonstrating advantages in deep-seated imaging and treatment. This approach opens up possibilities for the development of much lower dose X-ray-stimulated NIR-PLNPs in the future.

Summary: Microplastics pose potential hazards to human health and have gained increasing attention. While most studies focus on the characterization of microplastics in the environment, there is limited research on microplastics in solid foods. This study used three molecular spectral imaging approaches combined with chemometrics to characterize the presence of microplastics in corn flour. The results showed that the combination of Raman imaging and independent component analysis provided a better depiction of microplastics. Overall, this study demonstrates the potential of molecular spectral imaging for visual detection of microplastics in powdered food and provides a reference for the detection of microplastics in other foods.

Summary: In order to enhance the efficiency of g-C3N4 photocatalysts under solar light (UV about 5%, visible light about 43%, NIR light about 52%), recent progress of NIR-driven g-C3N4 based photocatalysts has been reviewed. Various strategies have been summarized to broaden the light absorption of g-C3N4 to NIR light region, and the diverse photocatalytic applications of NIR-driven g-C3N4 photocatalysts have been outlined.

Summary: Significance: Cerebrovascular impedance (CVI) is related to cerebral autoregulation (CA) and can serve as a biomarker for cerebral health. This study developed a method to quantify CVI based on a combination of diffuse correlation spectroscopy (DCS) and continuous wave near-infrared spectroscopy (NIRS) and validated the method on healthy human volunteers. The results showed that CVI changes can be reversed with postural changes, making it a potential tool for assessing cerebral health, especially in patients with altered cerebral perfusion pressure (CPP).

Summary: This study proposed an analytical framework to identify dynamic task-based functional connectivity (FC) features as new biomarkers of emotional sensitivity in nursing students using machine learning techniques. Results showed that nursing students were more susceptive to emotional stimuli and dynamic FC features provided a stronger discriminating power as biomarkers of emotional sensitivity.
