The increasing environmental crisis caused by plastic pollution, water contamination, and air pollution has driven the search for sustainable alternatives to conventional polymeric membranes. Polyhydroxyalkanoate (PHA)-based nanofiber membranes have emerged as biodegradable alternatives to conventional polymeric membranes, offering high porosity, tunable mechanical properties, and environmental co

Na2FePO4F is a promising cathode material for Na-ion batteries owing to its relatively high discharge voltage and excellent cycling performance. Now, the long- and short-range structural evolution of Na2FePO4F during cycling is studied by in situ high-energy X-ray diffraction (XRD), ex situ solid-state nuclear magnetic resonance (NMR), and first-principles DFT calculations. DFT calculations sugges

Histatins are a family of multifunctional, cationic histidine-rich saliva peptides. The most prominently represented are Histatin 1, Histatin 3, and Histatin 5. Despite considerable similarities in primary structure, the three members are known to display varied antimicrobial properties and healing abilities. This study aims to provide a detailed structural comparison of Histatin 1, Histatin 3, an

Propagation of intense X-ray pulses through dense media has led to the observation of phenomena such as atomic X-ray lasing1,2, self-induced transparency3 and stimulated X-ray Raman scattering (SXRS)4. SXRS has been long predicted as a means to launch and probe valence-electron wavepackets and as a building block for nonlinear X-ray spectroscopies5,6. However, experimental observations of SXRS to

Background In ovarian cancer (OvCa), achieving complete resection (RO) in initial surgery is crucial for improving prognosis. However, patients with undetected microscopic metastasis post-RO surgery often have poorer outcomes. This study explores prognostic factors for OvCa patients who underwent RO surgery, focusing on the role of ascites cytology as an indicator of microscopic peritoneal metasta

Recent hydrodynamical simulations of isolated barred disc galaxies have suggested a structural change in the distribution of the interstellar medium (ISM) around a stellar mass M∗ of 1010 M⊙. In the higher-mass regime (M∗ ≤ 1010 M⊙), we observe the formation of a central gas and stellar disc with a typical size of a few hundred parsecs connected through lanes to the ends of the stellar bar. In the

Background: There has been an increasing number of single-centre studies describing the long-term outcomes of patients with Hirschsprung disease. This study aimed to systematically review the literature on long-term bowel, urological, and sexual functional outcomes, fertility and quality of life in adults with Hirschsprung disease. Methods: A PROSPERO-registered systematic review of the English li

This work aims to differentiate strangeness produced from hard processes (jetlike) and softer processes (underlying event) by measuring the angular correlation between a high-momentum trigger hadron ((Formula presented)) acting as a jet proxy and a produced strange hadron [(Formula presented) meson]. Measuring (Formula presented) correlations at midrapidity in (Formula presented)-Pb collisions at

(Formula presented) boson events at the Large Hadron Collider can be selected with high purity and are sensitive to a diverse range of QCD phenomena. As a result, these events are often used to probe the nature of the strong force, improve Monte Carlo event generators, and search for deviations from standard model predictions. All previous measurements of (Formula presented) boson production chara

In this 5th version of the European LeukemiaNet guidance for adult patients, there are important changes in several areas of management based on evidence available since 2020, including the World Health Organisation’s reclassification of CML as a biphasic disease. Previous advice to switch the tyrosine kinase inhibitor (TKI) on failure of molecular milestones, is modified to better account for ind

Background: Neoadjuvant cisplatin-based combination chemotherapy (NAC) is standard perioperative treatment of patients with muscle-invasive urothelial bladder cancer (MIBC); however, about half of the patients experience recurrence of the disease. Biomarkers for response and survival represent an unmet medical need. We used tumor specimens from transurethral resections of the bladder to explore ge

Mononuclear iron(iv)-oxo, iron(iv)-imido and iron(iv)-nitrido complexes are common catalytic cycle intermediates in enzymes, where the metal is typically linked to the protein through cysteinate or histidine sidechains. Enzymatic high-valent iron(iv)-imido and -nitrido intermediates have never been trapped and characterized; hence, there is uncertainty regarding their structure and function. Using

Before performing 177Lu-DOTATATE therapy for neuroendocrine tumors, somatostatin receptor (SSTR) PET imaging is currently used to confirm sufficient tumor SSTR expression, but it also has potential to be used to personalize treatment by predicting absorbed doses to critical organs. This study aims to validate the predictive capability of SSTR PET in anticipating renal absorbed dose in the first cy

Objectives To study the prevalence of and interplay between common neuropsychiatric sequelae 3-4 years after onset of first-ever stroke - specifically post-stroke fatigue (PSF), post-stroke depression (PSD) and post-stroke cognitive impairment (PSCI). Design Population-based cohort study. Setting Catchment area of a Swedish University Hospital. Participants We recruited individuals with first-ever

Fire is a pivotal aspect of human involvement in the carbon cycle. However, the precise timing of the large-scale human fire use remains uncertain. Here, we report a pyrogenic carbon record of East Asian fire history over the past 300,000 y from the East China Sea. This record suggests a rapid increase in fire activity since approximately 50,000 y ago, indicating a decoupling from the monsoon clim

The Galactic center and inner disk of the Milky Way contain complex stellar populations obscured by heavy dust extinction. To study their chemical composition, high-resolution near-infrared (near-IR) spectroscopy is necessary. Expanding the set of elements measurable in the near-IR, especially neutron-capture elements, improves our ability to trace nucleosynthesis and Galactic chemical evolution.
