360; CI 0.161-0.801) among children in rural, but not urban, schools. The policies were also associated with greater activity levels and less frequent intake of unhealthy foods, particularly among children attending rural schools. Results were robust to stratification based on urbanicity of the installation versus school, omission of family covariates, and other sensitivity analyses. Falsification checks on children's height, parental BMI outcomes, home food environments and neighborhood environments indicate findings are not driven by selection. BMI assessment policies were associated with children's BMI outcomes and health behaviors in rural, but not urban schools.This study aimed to examine in a longitudinal cohort design whether social media use among adolescents is related to symptoms of social anxiety, depressed mood, and physical symptoms of anxiety over time. As part of the LIFECOURSE study of risk and protective factors for healthy adolescent development, three waves of school-based surveys of adolescents born in Iceland in 2004 were analyzed. Of the 3914 eligible adolescents, 2378 gave informed consent. Complete responses for this study were collected from 2211 students at the first wave, with 2052 responding roughly 12 months later, and 2097 responding in year 3. Linear mixed-effects models were used to analyze time spent on social media in relation to psychological distress over time. More time spent on social media was weakly but significantly associated with increased symptoms of depressed mood, social anxiety and symptoms of physical anxiety over time. However, the effect size of these relationships suggest they may not be of clinical relevance. The relationship between time spent on social media and symptoms of depressed mood and physical symptoms of anxiety grew stronger over time, although it is not known if this relationship is causal. The relationship between time spent on social media and all outcomes of psychological distress were stronger for girls than boys and increased social media use had a positive relationship with symptoms of depressed mood over time. The relationships found in this study were relatively small and future studies need to focus on the clinical and public health significance of these effects.Four new flavonoids (1-4) and fourteen known compounds (5-18), were isolated from the aerial part of Bupleurum chinense DC. The structural determination of the new flavonoids was accomplished using comprehensive spectroscopic methods, including 1D and 2D NMR spectra with references to the literatures, as well as high-resolution mass spectrometric analysis. The anti-proliferative activities of the flavonoids (1-18) against HeLa cells were evaluated using the MTT assay with cisplatin as the positive control.Seven new diterpenoid alkaloids, acotarines A-G (1-7), along with four known diterpenoid alkaloids, were isolated from Aconitum taronense. Their structures were established by 1D, 2D NMR spectra and HRESIMS data. Acotarine A (1) represents a franchetine-type alkaloid characterized by a N-butanone moiety. All the compounds were tested for their activities to induce lysosomal biogenesis through LysoTracker Red staining, compounds acotarines B (2), E (5), F (6), indaconitine (8), 7,8-epoxy-franchetine (9), and 6-epiforesticine (10) showed inducing lysosomal biogenesis activity.
Electrophysiological recordings of the brain often exhibit neural oscillations, defined as narrowband bumps that deviate from the background power spectrum. These narrowband dynamics are grouped into frequency ranges, and the study of how activities in these ranges are related to cognition and disease is a major part of the neuroscience corpus. Frequency ranges are nearly always defined according to integer boundaries, such as 4-8 Hz for the theta band and 8-12 Hz for the alpha band.

A data-driven multivariate method is presented to identify empirical frequency boundaries based on clustering of spatiotemporal similarities across a range of frequencies. The method, termed gedBounds, identifies patterns in covariance matrices that maximally separate narrowband from broadband activity, and then identifies clusters in the correlation matrix of those spatial patterns over all frequencies, using the dbscan clustering algorithm. Those clusters are empirically derived frequency bands, from which boundaries can be extracted.

gedBounds recovers ground truth results in simulated data with high accuracy. The method was tested on EEG resting-state data from Parkinson's patients and control, and several features of the frequency components differed between patients and controls.

The proposed method offers higher precision in defining subject-specific frequency boundaries compared to the current standard approach.

gedBounds can increase the precision and feature extraction of spectral dynamics in electrophysiology data.

The COVID-19 pandemic has had a far-reaching negative impact on healthcare systems worldwide and has placed healthcare providers under immense physiological and psychological pressures.

The aim of current study was to undertake an in-depth exploration of the experiences of health-care staff working during the COVID-19 crisis.

Using a thematic analysis approach, a qualitative study was conducted using semi-structured interviews with 97 health care professionals. Participants were health care professionals including pre-hospital emergency services (EMS), physicians, nurses, pharmacists, laboratory personnel, radiology technicians, hospital managers and managers in the ministry of health who work directly or indirectly with COVID-19 cases.

Data analysis highlighted four main themes, namely 'Working in the pandemic era', 'Changes in personal life and enhanced negative affect', 'Gaining experience, normalization and adaptation to the pandemic' and 'Mental Health Considerations' which indicated that mental ill deteriorations unfolded through a stage-wise process as the pandemic unfolded.

Participants experienced a wide range of emotions and development during the unfolding of the pandemic. Providing mental health aid should thus be an essential part of services for healthcare providers during the pandemic. Based on our results the aid should be focused on the various stages and should be individual-centred. Nintedanib Such interventions are crucial to sustain workers in their ability to cope throughout the duration of the pandemic.
