Proteomics analysis reveals the antagonistic interaction between high CO and warming in the adaptation of the marine diatom Thalassiosira weissflogii in future oceans.

While it is known that warming and rising CO level might interactively affect the long-term adaptation of marine diatoms, the molecular and physiological mechanisms underlying these interactions in the marine diatom Thalassiosira weissflogii on an evolutionary scale remain largely unexplored. In this study, we investigated the changes in metabolic pathways and physiological responses of T. weissflogii under long-term ocean acidification and/or warming conditions (∼3.

KDiffered brain spontaneous neural activity between limb-onset and bulbar-onset amyotrophic lateral sclerosis patients.

Purpose: To investigate the differences in brain spontaneous neural activity between limb-onset and bulbar-onset amyotrophic lateral sclerosis (ALS-L and ALS-B, respectively) patients using resting-state functional MRI (rs-fMRI) with amplitude of low-frequency fluctuation (ALFF) and regional homogeneity (ReHo).

Materials And Methods: The rs-fMRI data were collected from 41 ALS patients (11 ALS-B and 30 ALS-L) and 25 healthy controls (HC). ALFF and ReHo values were calculated, and group differences were assessed using one-way ANCOVA and two-sample t-tests.

Dual-band polarization-controlled metasurface with independent amplitude-phase coding for versatile beam forming.

Digital coding metasurfaces have gained considerable attention for their potential to bridge physical and information sciences. However, existing metasurfaces are often restricted to either phase-only or amplitude-only control and typically operate within a single frequency band or polarization, limiting their functionality in advanced electromagnetic applications. This study proposes a dual-band metasurface with independent amplitude-phase coding for polarization-controlled beam manipulation, addressing these limitations.

Comparing spirometry, impulse oscillometry with computed tomography for assessing small airway dysfunction in subjects with and without chronic obstructive pulmonary disease.

Background: Studies on consistency among spirometry, impulse oscillometry (IOS), and histology for detecting small airway dysfunction (SAD) remain scarce. Considering invasiveness of lung histopathology, we aimed to compare spirometry and IOS with chest computed tomography (CT) for SAD detection, and evaluate clinical characteristics of subjects with SAD assessed by these three techniques.

Methods: We collected baseline data from the Early COPD (ECOPD) study.
