Resonant inelastic X-ray scattering (RIXS) is an ideal X-ray spectroscopy method to push the combination of energy and time resolutions to the Fourier transform ultimate limit, because it is unaffected by the core-hole lifetime energy broadening. Also, in pump-probe experiments the interaction time is made very short by the same core-hole lifetime. RIXS is very photon hungry so it takes great advantage from high-repetition-rate pulsed X-ray sources like the European XFEL.

Background: After pneumococcal disease and colonization have been controlled through vaccination campaigns, a reduced pneumococcal conjugate vaccine (PCV) schedule may be sufficient to sustain that control at reduced costs.

Methods: We investigated whether a single primary dose and booster dose (1p+1) of the 10-valent PCV (PCV10) would be noninferior to alternative dose schedules in sustaining control of carriage of pneumococcal serotypes included in the vaccine. In Nha Trang, Vietnam, an area in which PCV had not been used previously, a PCV10 catch-up campaign was conducted in which the vaccine was offered to children younger than 3 years of age, after which a cluster-randomized trial was conducted in which children received PCV10 at 2, 3, and 4 months of age (3p+0 group); at 2, 4, and 12 months of age (2p+1 group); at 2 and 12 months of age (1p+1 group); or at 12 months of age (0p+1 group).

Breast cancer remains a prevalent global health challenge, with tumor-removal surgeries being among the most common treatments but often leading to aesthetic defects. Adipose-derived stem cell (ADSC)-enriched fat grafting in breast reconstruction offers promising therapeutic benefits. However, concerns about its oncological safety persist, particularly regarding the potential risks of promoting cancer recurrence.

We utilize a theoretical method based on nonlinear beam propagation and finite difference eigenmode solver methods to precisely simulate Gaussian beam propagation in electrical fields through spherical gradient refractive index lenses. The theoretical computation uses second-order partial differentiation of propagation coordinates to generate microwave field propagation. Consequently, it offers accurate simulation results for any complex refractive index profile.

Conotoxins, isolated from the venom of carnivorous marine snails of the Conus genus, are disulfide-rich peptides and proteins with well-defined three-dimensional structures. Conotoxins' ability to target a wide range of ion channels and receptors, including voltage- and ligand-gated ion channels, G protein-coupled receptors, monoamine transporters, and enzyme, at exquisite potency and selectivity make them valuable research and therapeutic tools. Despite their potentials, Conus venom peptides are present in limited quantities in nature and possess structural complexity that raises significant synthetic challenges for both chemical synthesis and recombinant expression.

Haematological and plasma parameters are used in veterinary medicine as a diagnostic tool, allowing for the early detection of potential health and welfare issues. For the implementation of monitoring strategies, reference intervals (RIs) are needed to know when deviations in those parameters become clinically relevant. Here, haematological and plasma biochemical RIs of Norwegian Atlantic salmon (Salmo salar Linnaeus) are presented for 29 biomarkers.

Understanding the mechanisms underlying a stable polarization at the surface of ferroelectric thin films is of particular importance both from a fundamental point of view and to achieve control of the surface polarization itself. In this study, we demonstrate that the X-ray standing wave technique allows the surface polarization profile of a ferroelectric thin film, as opposed to the average film polarity, to be probed directly. The X-ray standing wave technique provides the average Ti and Ba atomic positions, along the out-of-plane direction, near the surface of three differently strained [Formula: see text] thin films.

Article Synopsis
  • The superior shoulder suspensory complex (SSSC) is crucial for shoulder stability and is made up of multiple structures, including bones and ligaments; disruption of two or more leads to instability.
  • A 43-year-old woman experienced a rare case of triple disruption involving her acromion, coracoid process, and acromioclavicular joint after a car accident, requiring surgical intervention.
  • Treatment options vary for SSSC disruptions, with K-wire fixation chosen because of the patient’s smaller acromion size, emphasizing the need for personalized surgical approaches based on the injury specifics.

Article Synopsis
  • Dual antiplatelet therapy helps prevent serious blood clot events in patients with conditions like deep vein thrombosis and after stent placements, but it carries a significant risk of bleeding.
  • One of the most serious risks of this therapy is gastrointestinal bleeding, which accounts for nearly half of major bleeding incidents related to its use.
  • A case is presented involving a 74-year-old woman who experienced lower gastrointestinal bleeding after undergoing dual antiplatelet therapy, and she was successfully treated with an endovascular coil procedure.

Background: Injuries to the glenoid labrum have been recognized as a source of joint pain and discomfort, which may be associated with the inflammatory responses that lead to the deterioration of labral tissue. However, it is unclear whether the torn labrum prompts mast cell (MC) activation, resulting in synovial inflammatory responses that lead to labral tissue degeneration.

Purpose: To determine the potential influence of activated MC on synovial inflammatory responses and subsequent labral tissue degeneration and shoulder function deterioration in a rat model by monitoring MC behavior and sequential inflammatory responses within the synovial tissue and labral tissue after injury, suture repair, and MC stabilizer administration.

Purpose: Down syndrome (DS) is one of the most prevalent genetic diseases associated with a variety of ophthalmic disorders, including reported retinal abnormalities. Macular telangiectasia type 2 (MacTel 2) is a late-onset neurodegenerative retinal disease with a substantial genetic component. We hereby describe a case of a female with DS who presented with MacTel 2, and we discuss the possible pathways associating both entities.

  • The study focused on evaluating the antimicrobial resistance patterns in MRSA strains obtained from patients at Bac Ninh Provincial General Hospital in Vietnam, highlighting serious public health concerns.
  • Out of 15,232 clinical samples, 2.7% showed MRSA presence, with the majority coming from wound infections and surgical units.
  • The findings revealed high resistance rates, particularly to azithromycin, while MRSA strains remained fully susceptible to vancomycin, indicating an urgent need for better antibiotic management strategies.

Rationale: Gaucher disease (GD), an autosomal recessive lysosomal storage disease, results from GBA1 variants causing glucocerebrosidase (GCase) deficiency. While enzyme replacement therapy (ERT) helps with systemic symptoms, neurological complications in GD2 and GD3 persist due to the blood-brain-barrier (BBB) limiting ERT efficacy. Ambroxol, a BBB-permeable chaperone, enhances GCase activity.

A common approach to solve inverse imaging problems relies on finding a maximum a posteriori (MAP) estimate of the original unknown image, by solving a minimization problem. In this context, iterative proximal algorithms are widely used, enabling to handle non-smooth functions and linear operators. Recently, these algorithms have been paired with deep learning strategies, to further improve the estimate quality.

TnpB nucleases represent the evolutionary precursors to CRISPR-Cas12 and are widespread in all domains of life. IS605-family TnpB homologs function as programmable RNA-guided homing endonucleases in bacteria, driving transposon maintenance through DNA double-strand break-stimulated homologous recombination. In this work, we uncovered molecular mechanisms of the transposition life cycle of IS607-family elements that, notably, also encode group I introns.

In this report, we introduce a novel idea to prepare a redox additive in a gel polymer electrolyte system of PVA-ZnSO-HSO based on zinc-carbon battery recycling. Here, zinc cans from spent zinc-carbon batteries are dissolved completely in 1 M HSO to obtain a redox additive in an aqueous electrolyte of ZnSO-HSO. Moreover, carbon nanoparticles and graphene nanosheets were synthesized from carbon rod and carbon powder from spent zinc-carbon batteries by only one step of washing and electrochemical exfoliation, respectively, which have good electrochemical capability.
