Therapeutic effects of low-intensity transcranial focused ultrasound stimulation on ischemic stroke in rats: an in vivo evaluation using electrical impedance tomography.

Although previous studies have demonstrated that transcranial focused ultrasound stimulation protects the ischemic brain, clear criteria for the stimulation time window and intensity are lacking. Electrical impedance tomography enables real-time monitoring of changes in cerebral blood perfusion within the ischemic brain, but investigating the feasibility of using this method to assess post-stroke rehabilitation in vivo remains critical. In this study, ischemic stroke was induced in rats through middle cerebral artery occlusion surgery.

Influence of fermentation with lactic bacteria on the structure, functional properties and antioxidant activity of flaxseed gum.

Flaxseed meal is a by-product of flaxseed oil extraction. In this research, lactic acid bacteria suitable for modification of flaxseed gum were screened based on cellulase activity and the extraction rate of flaxseed gum. The enzyme-weight method was employed to extract flaxseed gum (SDF).

Identifying conservation and restoration priorities for degraded coastal wetland vegetations: Integrating species distribution model and GeoDetector.

The ongoing degradation of seagrass and seaweed is of global concern. Comprehending the spatial distribution of these wetland vegetation types and the threats they face becomes critical for effective conservation and restoration efforts. In this study, we combined a species distribution model and geographical detector to propose a novel framework for mapping the distribution and disturbance of degraded coastal wetland vegetation in sparsely recorded areas and identifying conservation and restoration priorities.

Ultrasonic neuromodulation mediated by mechanosensitive ion channels: current and future.

Ultrasound neuromodulation technology is a promising neuromodulation approach, with the advantages of noninvasiveness, high-resolution, deep penetration and good targeting, which aid in circumventing the side effects of drugs and invasive therapeutic interventions. Ultrasound can cause mechanical effects, activate mechanosensitive ion channels and alter neuronal excitability, producing biological effects. The structural determination of mechanosensitive ion channels will greatly contribute to our understanding of the molecular mechanisms underlying mechanosensory transduction.

Assessment of Multivariate Information Transmission in Space-Time-Frequency Domain: A Case Study for EEG Signals.

Objective: Multivariate signal (MS) analysis, especially the assessment of its information transmission (for example, from the perspective of network science), is the key to our understanding of various phenomena in biology, physics and economics. Although there is a large amount of literature demonstrating that MS can be decomposed into space-time-frequency domain information, there seems to be no research confirming that multivariate information transmission (MIT) in these three domains can be quantified. Therefore, in this study, we attempted to combine dynamic mode decomposition (DMD) and parallel communication model (PCM) together to realize it.

Impact of non-covalent bound polyphenols on conformational, functional properties and in vitro digestibility of pea protein.

This study investigated the effects of the non-covalent interaction of pea protein isolate (PPI) with epigallocatechin-3-gallate (EGCG), chlorogenic acid (CA) and resveratrol (RES) on the structural and functional properties of proteins. The conformational changes of the protein structure with EGCG, CA and RES were analyzed using fourier transform infrared spectroscopy. Polyphenols strongly quenched the intrinsic fluorescence of PPI mainly through static quenching.

Stability Analysis of fMRI BOLD Signals for Disease Diagnosis.

Previous studies have demonstrated that the stability changes in physiological signals can reflect individuals' pathological conditions. Apart from this, according to system science theory, a large-scale system can generally be divided into many subsystems whose stability level govern its overall performance. Therefore, this study attempts to investigate the possibility of analyzing the stability of decomposed subsystems of resting-state fMRI (rs-fMRI) BOLD signals in order to assess the overall characteristic of the human brain and individuals' health conditions.

Analysis of ECG Signals by Dynamic Mode Decomposition.

Objective: Based on cybernetics, a large system can be divided into subsystems, and the stability of each can determine the overall properties of the system. However, this stability analysis perspective has not yet been employed in electrocardiogram (ECG) signals. This is the first study to attempt to evaluate whether the stability of decomposed ECG subsystems can be analyzed in order to effectively investigate the overall performance of ECG signals, and aid in disease diagnosis.

Spectroscopic examination of effects of iodide on the chloramination of natural organic matter.

This study examined reactions of NOM with chloramine in the presence of varying iodide concentrations using in situ methods of absorbance and fluorescence. The data showed that the consumption of iodide during chloramination could be quantified by the differential absorbance of NOM at 225 nm. Examination of the kinetics of iodide consumption demonstrated the presence of two different reaction stages corresponding to the engagement of fast and slow reactive site in NOM.
