Using Compression Stockings to Prevent Recurrence of Vasovagal Syncope : A Randomized Sham-Controlled Trial

Background: Vasovagal syncope (VVS) is a common yet challenging condition with limited effective treatments. Elastic compression stockings (ECS) have been proposed as a potential therapy, but their real-world effectiveness remains unclear. Objectives: This study sought to compare the effectiveness of lower extremity compression with thigh-high ECS vs sham stockings for the prevention of VVS recurr

Multilevel small-area childhood stunting risk estimation: Insights from spatial ensemble learning, agro-ecological and environmentally remotely sensed indicators

Small area childhood stunting risk estimations remain a critical tool for shaping the surveillance policies of such a public health concern. With classical statistical methods, stunting risk metrics are mainly reported at a national level, which inhibits fine-scale insights at a more localized level. To this end, we implemented a novel multilevel small area estimation (SAE) approach for effectivel

Linear Regulator-based synchronization of positive discrete-time multi-agent systems

A fundamental challenge in control theory is designing protocols that achieve synchronization in interconnected systems. This paper addresses positive synchronization on undirected graphs for homogeneous discrete-time positive systems. It introduces a static feedback protocol derived from the Linear Regulator problem, where the stabilizing policy is determined by solving an algebraic equation usin

From Social Hubs to Silent Shops: The Impact of Unmanned Stores on Rural Community Life

This study explores how the emergence of unmanned stores impacts the sense of community in rural areas. It is set against the backdrop of increased urbanization, which threatens the survival of smaller rural communities. We study this through ethnographic inquiry into the emergence of unmanned stores. These have been introduced to counteract the depopulation of rural areas. We identify four ways i

Bystander behavior in workplace bullying : a vignette study exploring how organizational space and situational strength influence intentions to intervene

Purpose: The study explores how organizational space and situational strength influence bystanders’ intentions to intervene in workplace bullying within the healthcare sector. Design/methodology/approach: The research employs vignette-based interviews with 24 healthcare professionals from various medical fields in Sweden. The vignettes depict different bullying scenarios occurring in various spati

A multi-scaling approach showing a transient metabolic mismatch in a freshwater fish (Zingel asper) during an acute heat stress

Heat stress events will be more frequent and intense in the future. These events will challenge the capacity of organisms to exhibit sufficient metabolic flexibility to adapt to such variations. To better understand the acclimation processes implemented in response to acute warming, with an integrative approach we examined in vivo metabolic rate and cardiac mitochondrial respiration in the Rhône s

Integrative taxonomy, phylogeny and distribution patterns of the diverse Neotropical cloud forest butterfly genus Perisama Doubleday (Nymphalidae, Biblidinae, Callicorini)

Phylogenetic relationships of the predominantly Andean species-rich nymphalid genus Perisama are explored based on five genetic markers and a total of 3719 bps, and morphological characters of the adults with an emphasis on male genitalia and wing colour patterns. Its monophyly is recovered by including the genera Orophila, which turns out polyphyletic, and Mesotaenia. Two main, highly supported c

Persistent increase of Nogo-A-positive cells and dynamic reduction in oligodendroglia lineage cells in white matter regions following experimental and clinical traumatic brain injury

White matter (WM) disruption and atrophy is a consequence of traumatic brain injury (TBI) and contributes to persisting cognitive impairment. An increased expression of the myelin-associated axonal outgrowth inhibitor Nogo-A and oligodendrocyte pathology might be negatively associated with postinjury WM changes. Here, we analyzed brain tissue from severe TBI patients, obtained by surgical decompre

Bilayer orthogonal ferromagnetism in CrTe2-based van der Waals system

Systems with pronounced spin anisotropy are pivotal in advancing magnetization switching and spin-wave generation mechanisms that are fundamental to spintronic technologies. Quasi-van der Waals ferromagnets like Cr1+δTe2 represent seminal materials in this field, renowned for their delicate balance between frustrated layered geometries and magnetism. Despite extensive investigation, the nature of

Characterization of Portable Ultra-Low Field MRI Scanners for Multi-Center Structural Neuroimaging

The lower infrastructure requirements of portable ultra-low field MRI (ULF-MRI) systems have enabled their use in diverse settings such as intensive care units and remote medical facilities. The UNITY Project is an international neuroimaging network harnessing this technology, deploying portable ULF-MRI systems globally to expand access to MRI for studies into brain development. Given the wide ran

Charge carrier dynamics controlling performance of lead-based halide perovskite solar cells

We review our studies to assess charge carrier dynamics inside a perovskite film and interfacial charge transfer dynamics for a perovskite layer sandwiched by an electron transporting layer (ETL) such as TiO2 compact or mesoporous layer and a hole transporting layer (HTL) such as spiro-OMeTAD. Both electron and hole injection occur faster than electron-hole recombination inside a perovskite film,

Gene expression-based identification of prognostic markers in lung adenocarcinoma

Introduction Many studies have aimed at identifying additional prognostic tools to guide treatment choices and patient surveillance in lung cancer by assessing the expression of individual proteins through immunohistochemistry (IHC) or, more recently, through gene expression-based signatures. As a proof-of-concept, we used a multi-cohort, gene expression-based discovery and validation strategy to

Illuminating the Invisible: Green Fluorescent Protein as a Beacon for Antibiotic-Induced Phage Activity in Escherichia coli.

Background/Objectives: Antibiotic resistance presents an urgent public health threat. By developing a streamlined and effective method for studying bacteriophage induction, this research marks a step further in understanding how antibiotic-resistant genes might spread across different environments. This knowledge is essential for creating strategies to reduce the spread of antimicrobial resistanc
