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
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
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
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
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
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
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
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.

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
High-risk human papillomavirus (hrHPV) genotype is needed for adequate cervical cancer screening and HPV vaccination program evaluation as recommended by different guidelines. We aimed to assess the rate of HPV infection and HPV genotype distribution using vaginal self-sampling in a cohort of unscreened reproductive-age women in Ethiopia. A community-based cohort study was conducted with women age
Morphological traits of animals have evolved to solve ecological requirements, the optimization of locomotion in each environment being one of the most frequent selective forces shaping morphology. Amphisbaenians are strictly fossorial reptiles that have evolved various snout shapes for burrowing head-first underground, yet the evolutionary and ecological origins of these different morphologies ar
Skal danskerne til at lære dansk af svenskerne? Forskning og undervisning i dansk nedlægges ved Roskilde Universitets Center i 2028. Det sker, selv om 1/3 del af skoleeleverne på den sydlige del af Sjælland ikke bliver godkendt i dansk til eksamen i 9.klasse. I fremtiden skal danskerne måske til at rejse til Lund, Göteborg, Uppsala, Stockholm og Växjö for at studere deres eget sprog.
Dennis Olsson recenserar "Året hos Hyperboréerna", "Dagar den sommaren", samt "Norgesviten" av Jesper Svenbro, för poesikritksajten Örnen och Kråkans publik.
Moving beyond both utopian optimism's market-based solutions and terminal marketing's pessimism, this work introduces a dystopian optimism to revitalise critical marketing. We advocate for degrowth as an optimistic path forward and outline how marketing scholars can use critical performativity to be part of the transition to a post-growth economy.
Complicated colonic diverticulitis remains a frequent cause of hospital admissions in Western countries, associated with significant morbidity and health care utilization. Complications include abscess formation, perforation, sepsis, fistulas, and colonic stenosis, which may be present at initial presentation or develop during the disease course. Approximately 10%-20% of hospitalized diverticuliti
ObjectiveSputum cultures can guide antibiotic therapy, particularly in severe pneumonia or when resistant pathogens are suspected. However, data on how prior and ongoing antibiotic exposure affects microbial detection are limited. This study aimed to evaluate this impact, stratified by timing and route of administration.MethodsIn- and outpatients from nine hospitals in Skåne, Sweden, who submitted
