Signs of Hyperinflation and Ventilation Heterogeneity in Individuals With Severe Alpha-1-Antitrypsin Deficiency at the Age of 42

Background: Severe alpha-1-antitrypsin deficiency (AATD) is a known risk factor for early development of emphysema and COPD. By the Swedish national screening program within the years 1972–74 a cohort of individuals with severe AATD (PiZZ) was identified and regularly followed up. The aim of this study was to investigate alveolar volume (VA) and the ratio VA/Total lung capacity (VA/TLC) for the de

Electrographic and Clinical Determinants of Good Outcome After Postanoxic Status Epilepticus

Background and Objectives Postanoxic electrographic status epilepticus (PSE) affects up to a third of all comatose patients after cardiac arrest (CA) and is associated with high mortality. Late PSE onset (>24 hours), from a restored continuous background pattern, and absence of established indicators of poor outcome at multimodal prognostication are described in survivors. We aimed to determine th

Evaluation of Software-Optimized Protocols for Acoustic Noise Reduction During Brain MRI at 7 Tesla

Background: MR-generated acoustic noise may be particularly concerning at 7-Tesla (T) systems. Noise levels can be reduced by altering gradient output using software optimization. However, such alterations might influence image quality or prolong scan times, and these optimizations have not been well characterized. Purpose: To evaluate image quality, sound pressure levels (SPLs), and perceived noi

The role of microglia in the prion-like transmission of protein aggregates in neurodegeneration

Numerous neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease and amyotrophic lateral sclerosis share a neuropathological hallmark: aberrant protein aggregation in the CNS. Microglia, the brain's innate immune cells, also play a pivotal role in the pathogenesis of these disorders. Multiple studies indicate that these pathological aggregates can propagate throughout the brain

Some common statistical methods for assessing rater agreement in radiological studies

Rater agreement is commonly assessed in radiologic studies concerning image quality. There are several methods of measuring rater agreement. To choose the appropriate method, the researcher needs to consider the scale of the outcome variable and the design of the study. This article provides a brief overview of available methods, focusing on the most practical and commonly used, including intracla

Why Do Some Lineages Radiate While Others Do Not? Perspectives for Future Research on Adaptive Radiations

Understanding the processes that drive phenotypic diversification and underpin speciation is key to elucidating how biodiversity has evolved. Although these processes have been studied across a wide array of clades, adaptive radiations (ARs), which are systems with multiple closely related species and broad phenotypic diversity, have been particularly fruitful for teasing apart the factors that dr

Counter-diffusion studies of human transthyretin : the growth of high-quality crystals for X-ray and neutron crystallography

A crystallogenesis study of human transthyretin using the counter-diffusion method is described as an alternative to conventional convective vapour diffusion and batch approaches for protein crystallization. The X-ray diffraction results show systematic trends that exhibit unique patterns of crystallization and high crystal quality as well as a remarkable degree of coherence within extended crysta

Health professionals’ experiences delivering an Interdisciplinary Nurse-coordinated SELf-MAnagement intervention for patients with inflammatory arthritis

Purpose: The complex Interdisciplinary Nurse-coordinated SELf-MAnagement (INSELMA) intervention for patients with IA who experience substantial disease impact, was tested in a feasibility study. This study explored healthcare professionals’ (HPs) experiences of delivering the intervention. Materials and methods: A qualitative longitudinal evaluation study was conducted based on four focus group in

Arsine, Stibine and Phosphine Derivatives of [Fe2(CO)6(μ-bdt)] (bdt = Benzenedithiolate) : Syntheses, Structures and Spectroscopic and Electrocatalytic Studies

The reactivity of the benzenedithiolate (bdt)-bridged complex [Fe2(CO)6(µ-bdt)] with arsine, stibine and phosphine ligands has been studied. The new mono- and disubstituted complexes [Fe2(CO)5(EPh3)(µ-bdt)] (E = As, 1; E = Sb 3) and [Fe2(CO)4(EPh3)2(µ-bdt)] (E = As, 2; E = Sb, 4) and the previously reported [Fe2(CO)4(PPh2H)2(µ-bdt)] (5) have been prepared by Me3NO-initiated carbonyl substitution r

Prevalence of Contact Allergy to Propolis—Testing With Different Propolis Patch Test Materials

Introduction: Propolis is a sticky substance produced by honeybees from plant resins collected from locally growing vegetation. Its chemical composition varies depending on the plant species visited by the bees. Contact dermatitis is commonly reported following exposure to cosmetics containing propolis or following the intake of food supplements. Objectives: To investigate the prevalence of contac

Influence of degradation products from thermal wood modification on wood-water interactions

Thermal modification is a widely used technology for enhancing the dimensional stability and durability of wood. However, thermal degradation reactions in wood are complex and depend on the process conditions applied. Degradation products from thermal wood modification are expected to affect the wood chemistry and the wood–water interactions of the thermally modified wood. In this paper, we invest

Use of Biopowders as Adsorbents of Potentially Toxic Elements Present in Aqueous Solutions

This study examines the adsorption and desorption behaviors of phosphorus (P), arsenic (As), fluoride (F), and chromium (Cr) in aqueous solutions on green materials such as cork bark (CB) and pine bark (PB). These materials are characterized by active functional groups and net negative charges on their surfaces and porous structures. The evaluation considers variations in contaminant concentration

A framework for neural organoids, assembloids and transplantation studies

As the field of neural organoids and assembloids expands, there is an emergent need for guidance and advice on designing, conducting and reporting experiments to increase the reproducibility and utility of these models. In this Perspective, we present a framework for the experimental process that encompasses ensuring the quality and integrity of human pluripotent stem cells, characterizing and man

The Role of Geometry in Mg Implant Design

During the last decades, MgMg and alloys gained interest as degradable implant materials: its mechanical propertiesMechanical properties are close to bone and a second surgery for removing them can be avoided. Properties are gained from chemical composition and processing as they are responsible for microstructureMicrostructure development. However, this is not good enough in many cases. When the

Enlarged cavum septum pellucidum as a neuroimaging signature of head impact exposure

Cavum septum pellucidum (CSP) is commonly observed upon neuroimaging examination in individuals exposed to repetitive head impacts (RHI) and post-mortem in cases with chronic traumatic encephalopathy. Consequently, CSP has been proposed as a potential biomarker for RHI-related neurodegeneration, yet prevalence estimates of CSP across other neurodegenerative diseases and its clinical implications a

Forced Into an Ableist Narrative? The Swedish Covid Association’s Quest for Recognition

During the COVID-19 pandemic, the Swedish Covid Association (SCA) was established to represent individuals with Long COVID (LC). The unique Swedish response to the pandemic, characterized by minimal restrictions, serves as the backdrop for the SCA’s efforts to highlight the specific needs of LC patients, who were largely excluded from pandemic policies and protective measures.

Interaction of ions and surfactants at the seawater-air interface

The interface of the oceans and aqueous aerosols with air drives many important physical and chemical processes in the environment, including the uptake of CO2 by the oceans. Transport across and reactions at the ocean-air boundary are in large part determined by the chemical composition of the interface, i.e., the first few nanometers into the ocean. The main constituents of the interface, beside
