Heart failure in Southern Sweden (HISS) : a cross-sectional analysis of primary care patients’ characteristics and physicians’ adherence to guideline-directed medical therapy

Objectives We aimed to describe clinical and diagnostic characteristics of primary care patients with heart failure and physicians’ adherence to guideline-directed medical therapy (GDMT) for treating chronic heart failure. Design Cross-sectional study based on baseline data from the prospective primary care-based study Heart failure in Southern Sweden (HISS). Setting Patients with heart failure we

Genetic drivers of heterogeneity in type 2 diabetes pathophysiology

Type 2 diabetes (T2D) is a heterogeneous disease that develops through diverse pathophysiological processes1,2 and molecular mechanisms that are often specific to cell type3,4. Here, to characterize the genetic contribution to these processes across ancestry groups, we aggregate genome-wide association study data from 2,535,601 individuals (39.7% not of European ancestry), including 428,452 cases

Development of high affinity antibodies to Plasmodium falciparum merozoite and sporozoite antigens during infancy and adulthood

Antibodies are important for protection against malaria. For optimal protective activity, it is thought that antibodies need to have high affinity. A longitudinal study conducted in Uganda followed newborn infants and their mothers for nine months. The study found that antibody affinity (here measured as dissociation rate constant, kd) against the merozoite antigens AMA1 and MSP2 decreased from bi

The visual system of a nocturnal long-distance migrant, the Australian Bogong moth

The Australian Bogong moth (Agrotis infusa) is a small noctuid moth that undertakes annual, nocturnal migrations of up to 1000 km to escape the summer heat of its breeding grounds. The moths travel to cool alpine caves, where they enter a dormant state (aestivation) before returning to reproduce and die. During migration, their brains integrate magnetic and visual cues to guide their flight direct

The low complexity linker of DNAJB6b is key to its anti-amyloid function

Neurodegenerative disorders, such as Alzheimer's and Parkinson's diseases, are associated with the formation of amyloid fibrils. The DNAJB6b (JB6) chaperone greatly inhibits the disease-related self-assembly of amyloid peptides in an ATP-independent manner. The molecular basis of this process is, however, not understood. Here, we studied the low complexity linker between the N- and C-terminal doma

MIFA : Metadata, Incentives, Formats and Accessibility guidelines to improve the reuse of AI datasets for bioimage analysis

Artificial intelligence (AI) methods are powerful tools for biological image analysis and processing. High-quality annotated images are key to training and developing new algorithms, but access to such data is often hindered by the lack of standards for sharing datasets. We discuss the barriers to sharing annotated image datasets and suggest specific guidelines to improve the reuse of bioimages an

The missing data for intelligent scientific instruments

Most scientific instruments currently discard rich streams of commands, data and metadata from which AI systems could learn to conduct experiments with expert-level decision-making and troubleshooting skills. Recording and using this data at scale requires rethinking what data to store, incentivizing large-scale cooperation, and determining how to quantify the reliability of such autonomous system

Effect of noble metals on the performance of Ni–Mo catalysts for the hydrodeoxygenation of lignin oils to fuels

Improving the catalytic performance in the hydrodeoxygenation (HDO) of lignin oils to produce liquid fuels, while meeting industrial requirements, is important for addressing current environmental challenges. In the present study, the promoting effects of noble metals (Pd, Pt, and Ir) on the performance of the Ni–Mo/CeLa/Al2O3 catalyst were investigated in the HDO of a lignin-derived pyrolysis oil

ISHLT Consensus Statement on the Perioperative use of ECLS in Lung Transplantation : Part III: Postoperative Considerations

The use of extracorporeal life support (ECLS) throughout the perioperative phase of lung transplantation requires nuanced planning and execution by an integrated team of multidisciplinary experts. To date, no multidisciplinary consensus document has examined the perioperative considerations of how to best manage these patients. To address this challenge, this perioperative utilization of ECLS in l

Bifunctional SERS-Fenton micro-nano platform : Integrating ultrasensitive sensing with advanced oxidation for the detection and degradation of organic pollutants in water

Organic pollutants in aquatic environments pose a threat to ecosystems and human health, a challenge that requires urgent resolution. This urgent threat highlights the need for the development of efficient technologies for pollutant detection and degradation in environmental protection. This study presents the successful fabrication of a composite nanomaterial consisting of Ag nanoparticle-decorat

Dynamics of lifting the Au(111) reconstruction in perchloric acid electrolyte

The striped p × √3 reconstruction of Au(111) is a textbook example of how electrode surfaces reorganise in response to an applied potential. Using in situ high-energy surface X-ray diffraction, we track the surface reconstruction in 0.1 M HClO4electrolyte while the potential is cycled at both 5 mV s−1and 2 mV s−1between 0.06 V and 0.86 V versus RHE. Reciprocal-space maps, collected every ∼10 s, sh

Dimensionality-dependent electronic and vibrational dynamics in low-dimensional organic-inorganic tin halides

Photo-induced dynamics of electronic processes are driven by the coupling between electronic and nuclear degrees of freedom. Here, we construct one- and two-dimensional organic-inorganic tin halides to investigate how dimensionality controls exciton-phonon coupling and exciton self-trapping. The results show that a one-dimensional system has strong exciton-phonon coupling leading to excitation-ind

Does amyloid fibril nucleation occur at surfaces only?

The Aβ42 peptide (APP(672–713)), associated with Alzheimer disease, is highly prone to form amyloid fibrils and has been extensively studied through in vitro experiments. Such experiments represent a basis for understanding the biophysical chemistry of amyloid-related diseases. In this communication, we show that homogeneous primary nucleation in vitro of Aβ42 fibrils is a very rare event, implyin

Solubility and Metastability of the Amyloidogenic Core of Tau

Intracellular deposits of neurofibrillary tau tangles and extracellular Aβ plaques are closely associated with Alzheimer’s disease. The mapping of thermodynamic parameters, including solubility limits, indicates when a protein forms amyloid fibrils or remains in solution. This reveals the direction of change of the system and may help in understanding drift and steady states in living systems. Her

Photocurrent detected 2D spectroscopy via a pulse shaper : insights and strategies for optimally untangling the nonlinear response

Action-detected two-dimensional electronic spectroscopy (A-2DES) provides valuable insights into ultrafast dynamics within functional materials and devices by measuring incoherent signals like photocurrent. This work details the implementation and optimization of a pulse-shaper-based A-2DES setup, focusing on methodological strategies crucial for acquiring high-fidelity data. We present a comprehe

Strain-stress relationships for coherent in-plane strain in heterostructures with monoclinic crystal systems : β-(AlxGa1−x)2O3 on (h0l)β-Ga2O3 as example

In this work, we derive the relationship between the states of strain and stress in pseudomorphic epitaxial layers on a substrate with differing equilibrium lattice parameters under symmetry-conserving conditions for the case of monoclinic crystal symmetry. We compare surface vectors across the template-epitaxial layer interface and impose conditions of a stress-free epitaxial layer. As a result,
