Biomarkers.

Background: Epigenetic clocks are biomarkers of biological age based on DNA methylation (DNAm) patterns and are widely used as predictors of health and aging outcomes. Multiple epigenetic clocks have been developed and reflect different aspects of the multidimensional aging process, above and beyond chronological age. To date, no study has examined the relationship of epigenetic aging with circulating biomarkers of Alzheimer's Disease (AD).

Biomarkers.

Background: The medial temporal lobe (MTL) is the epicenter of both primary and concomitant molecular pathologies in Alzheimer's disease (AD). The intricate anatomy of the MTL has been the subject of extensive study over the past two centuries. However, current PET and MRI AD biomarkers use often crude parcellations of the MTL that have not been sufficiently validated vis-à-vis anatomical ground truth.

Public Health.

Background: Mild traumatic brain injury (mTBI) increases dementia risk. Delays in diagnosis are common due to insensitive tools, prolonging symptoms and time to treatment. Dual-task gait and functional mobility deficits are present post-mTBI and in people living with dementia (PWD); however, it is unclear whether dual-tasking can be used as a tool to differentiate between groups.

Multi-omics profiling reveals altered mitochondrial metabolism in adipose tissue from patients with metabolic dysfunction-associated steatohepatitis.

Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) and its more severe form steatohepatitis (MASH) contribute to rising morbidity and mortality rates. The storage of fat in humans is closely associated with these diseases' progression. Thus, adipose tissue metabolic homeostasis could be key in both the onset and progression of MASH.

Is the YES/NO classification accurate in screening scapular dyskinesis in asymptomatic individuals? - A novel validation study utilizing surface electromyography as a surrogate measure in identifying movement asymmetries.

Background: Scapular dyskinesis is a known risk factor for shoulder pain, making it important to screen for prevention. Physical therapists screen scapular dyskinesis by visually comparing asymmetries in scapular movement during overhead reach using the Scapular Dyskinesis Test Yes/No classification (Y/N). Although scapular kinematics has been used to quantify scapular dyskinesis, current measurement techniques are inaccurate.

Leveraging Urban Water Distribution Systems with Smart Sensors for Sustainable Cities.

Optimizing urban water distribution systems is essential for reducing economic losses, minimizing water wastage, and addressing resource access gaps, particularly in drought-prone regions impacted by climate change. We apply advanced artificial intelligence (AI) techniques and the Internet of Things (IoT) to optimize water networks in Spain using simulation. By employing EPANET for hydraulic modeling and a linear regression-based algorithm for optimization, we achieved up to 96.

Design, Setting And Participants: Football players who were eligible for this randomized controlled study were randomly assigned (allocation ratio 1:1:1) to one of three groups: experimental group, placebo group or control.

Interventions: The experimental group received kinesiological tape bands applied to the peroneal and tibialis anterior muscles.

Association between sleep quality and weight gain in pregnancy: a cross-sectional study.

Introduction: There are grounds for the hypothesis that poor sleep quality, regardless of the pre-gestational nutritional status, is a risk factor for inadequate gestational weight gain.

Objective: To investigate the association between sleep quality and insufficient or excessive gestational weight gain in Brazilian pregnant women without gestational complications and monitored in public prenatal care units.

Methods: This is a cross-sectional study nested within a cohort study that reviewed pregnant women's mental health, sleep, and nutritional outcome.

Clearing the air: Heightened perception of harm from secondhand cannabis smoke exposure is associated with no in-home cannabis smoking in a 21-country convenience sample.

Objective: As countries adopt more lenient cannabis use policies, perception of harm from secondhand cannabis smoke (SHCS) exposure is decreasing and most cannabis smoking is taking place at home. We quantified the relationship of reported in-home cannabis smoking with perceived harm from SHCS exposure.

Methods: The analytic sample comprised 28,154 adult respondents, from 21 countries, to the annual cross-sectional Global Drug Survey (2021) of users of licit or illicit drugs.

Urea assimilation and oxidation support activity of phylogenetically diverse microbial communities of the dark ocean.

Urea is hypothesized to be an important source of nitrogen and chemical energy to microorganisms in the deep sea; however, direct evidence for urea use below the epipelagic ocean is lacking. Here, we explore urea utilization from 50 to 4000 meters depth in the northeastern Pacific Ocean using metagenomics, nitrification rates, and single-cell stable-isotope-uptake measurements with nanoscale secondary ion mass spectrometry. We find that on average 25% of deep-sea cells assimilated urea-derived N (60% of detectably active cells), and that cell-specific nitrogen-incorporation rates from urea were higher than that from ammonium.

Validation of a Urine-Based Proteomics Test to Predict Clinically Significant Prostate Cancer: Complementing mpMRI Pathway.

Introduction: Prostate cancer (PCa) is the most frequently diagnosed cancer among men. A major clinical need is to accurately predict clinically significant PCa (csPCa). A proteomics-based 19-biomarker model (19-BM) was previously developed using capillary electrophoresis-mass spectrometry (CE-MS) and validated in close to 1,000 patients at risk for PCa.

Dynamics of Photoinduced Charge Carriers in Metal-Halide Perovskites.

The measurement and description of the charge-carrier lifetime (τc) is crucial for the wide-ranging applications of lead-halide perovskites. We present time-resolved microwave-detected photoconductivity decay (TRMCD) measurements and a detailed analysis of the possible recombination mechanisms including trap-assisted, radiative, and Auger recombination. We prove that performing injection-dependent measurement is crucial in identifying the recombination mechanism.

Glioblastoma functional heterogeneity and enrichment of cancer stem cells with tumor recurrence.

Glioblastoma (GBM) is an incurable disease with high intratumoral heterogeneity. Bioinformatic studies have examined transcriptional heterogeneity with differing conclusions. Here, we characterize GBM heterogeneity and highlight critical phenotypic and hierarchical roles for quiescent cancer stem cells (qCSCs).
