Transmission of Knowledge, Crafting and Cultural Traditions, Interregional Contact and Interaction, 7300 Cal BC

The newly discovered site of Norje Sunnansund, located in south-eastern Sweden, presents great potential for analysing the origin of technological change in postglacial Europe based on transmission patterns through the technological analysis of Mesolithic material production and how manufacturing techniques and implements were distributed chronologically and geographically. The study shows that ma

Recommendations, guidelines, and best practice for the use of human induced pluripotent stem cells for neuropharmacological studies of neuropsychiatric disorders

The number of individuals suffering from neuropsychiatric disorders (NPDs) has increased worldwide, with 3 million disability-adjusted life-years calculated in 2019. Though research using various approaches including genetics, imaging, clinical and animal models has advanced our knowledge regarding NPDs, we still lack basic knowledge regarding the underlying pathophysiological mechanisms. Moreover

Preclinical Studies Design and Place of Rabbits

The rabbit is a common laboratory animal used for research in dental implants, mainly as a screening model. It has many advantages compared to other laboratory animals. Availability, handling, cost-effectiveness, and early skeletal maturity are a few. For the model’s validity, there need to be similarities to the human. Although there are similarities between human and rabbit anatomy, there are al

Advanced technological approaches and market status analysis of xylose bioconversion and utilization : Xylooligosacharides and xylonic acid as emerging products

The efficient conversion of xylose is a short board of cask effect to lignocellulosic biorefining, by markedly affecting the total economic and environmental benefits. Based on a comprehensive analysis of the current commercial status of traditional xylose utilization and industrial technology development, this review outlines new technological avenues for the efficient utilization of xylose from

Lessons Learned from Early Implementation and Scale-up of Stool-Based Xpert Testing to Diagnose Tuberculosis in Children

In 2020, fecal (stool) testing was recommended for diagnosing Mycobacterium tuberculosis complex (MTBC) infection in children by using the Cepheid Xpert MTB/RIF assay; since then, countries have begun implementing stool-based testing, often as part of a comprehensive strategy to enhance TB case finding among children. On the basis of an experience-sharing workshop in November 2023, we determined i

The yield of community-based tuberculosis and HIV among key populations in hotspot settings of Ethiopia : A cross-sectional implementation study

Objective To determine the yield of tuberculosis (TB) and the prevalence of Human Immuno-deficiency virus (HIV) among key populations in the selected hotspot towns of Ethiopia. Methods We undertook a cross-sectional implementation research during August 2017-January 2018. Trained TB focal persons and health extension workers (HEWs) identified female sex workers (FSWs), health care workers (HCWs),

Nanofibrous Peptide Hydrogels Leveraging Histidine to Modulate pH-Responsive Supramolecular Assembly and Antibody Release

In this work, we investigate the pH-responsive behavior of multidomain peptide (MDP) hydrogels containing histidine. Small-angle X-ray scattering confirmed that MDP nanofibers sequester nonpolar residues into a hydrophobic core surrounded by a shell of hydrophilic residues. MDPs with histidine on the hydrophilic face formed nanofibers at all pH values tested, but the morphology of the fibers was i

Yttrande för remissen : Vissa åtgärder för stärkt återvändandeverksamhet och utlänningskontroll (SOU 2024:80) Ju2024/02572

Samhällsvetenskapliga fakulteten är kritiska till utredningens förslag med undantag för enstaka delar där vi inte har några synpunkter, samt något förslag som vi tillstyrker. Samhällsvetenskapliga fakulteten avråder från att gå vidare med fler skarpa lagförslag som tar samhällsutvecklingen i en riktning där människor håller sig undan myndighetskontakter, och som leder till förtroendeskador gentemo

In Operando Locally-Resolved Photophysics in Perovskite Solar Cells by Correlation Clustering Imaging

The instability of metal halide perovskites limits the commercialization of solar cells despite their impressive efficiencies. This instability, driven by photo-induced ion migration, leads to material restructuring, defect formation, degradation, and defect healing. However, these same “unwanted” properties enable to propose Correlation Clustering Imaging (CLIM), a technique that detects local ph

Evolved and Plastic Gene Expression in Adaptation of a Specialist Fly to a Novel Niche

How gene expression evolves to enable divergent ecological adaptation and how changes in gene expression relate to genomic architecture are pressing questions for understanding the mechanisms enabling adaptation and ecological speciation. Furthermore, how plasticity in gene expression can both contribute to and be affected by the process of ecological adaptation is crucial to understanding gene ex

Difficult cannulation during endoscopic retrograde cholangiopancreatography—needle-knife precut versus transpancreatic sphincterotomy on the basis of successful cannulation and adverse events

Background: When cannulation is challenging during endoscopic retrograde cholangiopancreatography (ERCP), and the standard guidewire technique with sphincterotomy is unsuccessful, alternative cannulation techniques can be used to access the biliary tree. The purpose of this study was to compare the incidence of adverse events and cannulation success rates between transpancreatic sphincterotomy (TP

Pluripotent stem-cell-derived therapies in clinical trial : A 2025 update

Since the first derivation of human pluripotent stem cells (hPSCs) 27 years ago, technologies to control their differentiation and manufacturing have advanced immensely, enabling increasing numbers of clinical trials with hPSC-derived products. Here, we revew the landscape of interventional hPSC trials worldwide, highlighting available data on clinical safety and efficacy. As of December 2024, we

ESTRO/EANO recommendation on reirradiation of glioblastoma

Background and Purpose: Although reirradiation of glioblastoma has a long history of clinical practice, guidance on how to perform it in the context of recent technological advances, modern imaging modalities or systemic therapy is scarce. This joint ESTRO/EANO guideline aims to collect the existing evidence to produce recommendations for safe reirradiation of glioblastoma. Methods: The basis of t

Neuronal CD59 isoforms IRIS-1 and IRIS-2 as regulators of neurotransmitter release with implications for Alzheimer’s disease

We have previously demonstrated that the intracellular, non-GPI anchored CD59 isoforms IRIS-1 and IRIS-2 (Isoforms Rescuing Insulin Secretion 1 and 2) are necessary for insulin secretion from pancreatic β-cells. While investigating their expression across human tissues, we identified IRIS-1 and IRIS-2 mRNA in the human brain, though their protein expression and function remained unclear. This stud

Pulmonary exposure to renewable diesel exhaust particles alters protein expression and toxicity profiles in bronchoalveolar lavage fluid and plasma of mice

Exposure to diesel exhaust is associated with increased risk of cardiovascular and lung disease. Substituting petroleum diesel with renewable diesel can alter emission properties but the potential health effects remain unclear. This study aimed to explore toxicity and underlying mechanisms of diesel exhaust from renewable fuels. Using proximity extension assay (Olink), 92 proteins linked to inflam

Semi-standardized evaluation of extraprostatic extension and seminal vesicle invasion with [18F]PSMA-1007 PET/CT : a comparison to MRI using histopathology as reference

Background: Positron emission tomography/computed tomography (PET/CT) with prostate specific membrane antigen ligands (PSMA) is established for use in primary staging of prostate cancer to screen for metastases. It has also shown promise in local tumor staging, including detection of extraprostatic extension (EPE) and seminal vesicle invasion (SVI). Previous studies have shown high heterogeneity i

Precarious employment, strenuous working conditions and the long-term risk of diagnosed chronic musculoskeletal disorders

Objectives To investigate the effect of precarious employment (PE) on the risk of diagnosed chronic musculoskeletal disorders (MSDs) among Swedish workers in occupations with strenuous working conditions. Methods This nationwide register-based cohort study included workers registered as living in Sweden in 2005, aged 21-60 at the 2010 baseline. Three samples were included: workers with high biomec
