Serum Mediated Phagocytosis Of Necrotic Material By Polymorphonuclear Leukocytes May Be Used As a Tool To Predict Clinical Manifestations In Systemic Lupus Erythematosus
Highly-destabilized ligand field excited states of iron carbene complexes and their relation to charge transfer state lifetimes
Lifetimes of photoexcited charge transfer (CT) states in transition metal chromophores are influenced by low-lying ligand field (LF) excited states, especially for 3d metal complexes. To manipulate interactions between LF and CT states, it is important to be able to control LF excited state energies using tunable synthetic variables. In this report, we use Fe 2p3d L3-edge resonant inelastic X-ray
ROS activity in carbonaceous nanoparticles : the influence of surface area and chemistry
Carbon Black (CB), graphene, and nanodiamond are distinct carbonaceous insoluble nanoparticles. Reactive Oxygen Species (ROS) associated with these particles play a significant role in both in vivo and in vitro toxicity evaluations. Accurate assessment of ROS activity is relevant for toxicity screening and in ensuring safe working environments as well as guiding the innovation by safe-and-sustaina
Multiexciton absorption cross sections of CdSe@CdS nanorods studied using pump–repump–probe spectroscopy
While the multiexciton dynamics in semiconductor nanocrystals is widely explored, to determine the absorption cross sections for multiexcitons of varying order is still a challenge. In this study, we performed pump–repump–probe transient absorption (ppp-TA) spectroscopic measurements on CdSe@CdS nanorods to gain insights into the absorption cross sections for multiexcitons. By tuning the pump–repu
Self- and co-assembly of the amyloid suppressing chaperone DNAJB6b
The clustering of certain proteins into oligomers and fibrils, known as amyloids, underlies the pathology of diseases such as Alzheimer’s disease, Parkinson’s disease, and type 2 diabetes. These processes are counteracted by the cellular protein quality control system, which includes molecular chaperones that interact with disease-associated proteins. One such chaperone is DNAJB6b, which has gaine
Mepolizumab versus benralizumab for eosinophilic granulomatosis with polyangiitis (EGPA): A European real-life retrospective comparative study
Background: Following the results of the MANDARA trial, this real-life study aimed at comparing the effectiveness and safety profile of mepolizumab versus benralizumab in a European EGPA cohort. Methods: We conducted a retrospective observational comparative study including EGPA patients, who received mepolizumab or benralizumab at the asthma dose. Patients were matched 1:1 by sex, age, BVAS and o
How Antisolvent-Induced Ligand Stripping Shapes CsPbX3 Nanocrystals and Their Assemblies
Supercrystals of lead-halide perovskite nanocrystals combine the semiconducting properties of bulk perovskites with quantum confinement effects and extend them to the macroscopic scale. Supercrystals assembled via a two-layer phase diffusion process using an acetonitrile antisolvent were recently shown to be unusually robust. We investigate how the acetonitrile-assisted self-assembly process influ
An unusual case of Streptococcus pyogenes infective endocarditis demonstrating the usefulness of repeated echocardiography
Infective endocarditis (IE) is most often caused by alpha-hemolytic streptococci or Staphylococcus aureus and is characterized by the presence of vegetations on the heart valves. Here we present a case of IE caused by Streptococcus pyogenes, a distinctly uncommon IE-pathogen, where no vegetations could be visualized on repeated echocardiography. Diagnosis was instead evident from septic embolizati
Economic evaluation of diabetes prevention interventions in Bangladesh : A modelling study
Aim: To model the long-term cost-effectiveness of scaling up two prevention interventions against type 2 diabetes mellitus (T2DM), i.e. community mobilisation through participatory learning and action (PLA) and mHealth mobile phone messaging, implemented in rural Bangladesh as part of the “DMagic” trial. Methods: A health-economic Markov model of the three-arm, cluster-randomised controlled DMagic
National implementation of vaginal Natural Orifice Transluminal Endoscopic Surgery for benign hysterectomies : A historical cohort study of Swedish data 2021–2023
Introduction: Vaginal Natural Orifice Transluminal Endoscopic Surgery (vNOTES) is a technique combining vaginal entrance to the abdomen with endoscopic overview. Previous studies have shown that vNOTES decreases operating time, hospitalization, postoperative complications, and pain. We aimed to present patient demographics, costs, and surgical outcomes following the implementation of vNOTES for be
Methodologies for velocimetry and flow visualization in supersonic flows enabled by CO2 seeding
A high spatiotemporal resolution technique for instantaneous flow field measurement has been developed, enabling one-dimensional velocimetry and flow field visualization within a converging–diverging nozzle. By employing femtosecond laser-induced long-lived, high-intensity plasma emission in a CO2/N2 gas flow, coupled with an ICCD camera, we achieved instantaneous one-dimensional velocity measurem
Transport of Dipolar Excitons at the Type-II Polytype Interface of InP Platelets
The pursuit of high charge carrier mobility in nanostructures is crucial for advancing both device development and exploring fundamental physics. This study focuses on minimizing scattering to achieve high mobility, employing a polytype type-II interface formed between wurtzite and zincblende InP. On the zincblende side, electrons accumulate, while holes gather on the wurtzite side, resulting in t
Peripherally administered TNF inhibitor is not protective against α-synuclein-induced dopaminergic neuronal death in rats
The underlying cause of neuronal loss in Parkinson's disease (PD) remains unknown, but evidence implicates neuroinflammation in PD pathobiology. The pro-inflammatory cytokine soluble tumor necrosis factor (TNF) seems to play an important role and thus has been proposed as a therapeutic target for modulation of the neuroinflammatory processes in PD. In this regard, dominant-negative TNF (DN-TNF) ag
Temporal artery biopsy in giant cell arteritis : clinical perspectives and histological patterns
Although its role has been debated, temporal artery biopsy (TAB) remains the gold standard for the diagnosis of cranial giant cell arteritis (GCA). The specificity of TAB is excellent and the sensitivity, albeit lower, is comparable with other diagnostic modalities used for the diagnosis of GCA. This outpatient procedure has a low rate of complications and is well integrated in the majority of hea
Microheater Controlled Crystal Phase Engineering of Nanowires Using In Situ Transmission Electron Microscopy
Crystal Phase Quantum Dots (CPQDs) offer promising properties for quantum communication. How CPQDs can be formed in Au-catalyzed GaAs nanowires using different precursor flows and temperatures by in situ environmental transmission electron microscopy (ETEM) experiments is studied. A III-V gas supply system controls the precursor flow and custom-built micro electro-mechanical system (MEMS) chips wi
Assessing housing accessibility issues for older adults in Japan : an expert panel approach to cross-cultural adaptation and content validity of the Japanese housing enabler
Accessible housing plays a crucial role in supporting aging in place, yet Japan lacks adequate tools for assessing housing accessibility among older adults. This study describes the process of translating and adapting the environmental component checklist of the Swedish Housing Enabler instrument for valid use in Japan. During translation to the Japanese language, technical terms and specification
Comparing phase sensitive detection and Fourier analysis of modulation excitation spectroscopy data exemplified by Ambient Pressure X-ray Photoelectron Spectroscopy
Dynamic processes in catalysis are gaining increased attention and could very well be one of the next frontiers in surface science. One way to study such processes is to induce chemical changes on the surface for example by periodically adjusting the (electro)chemical potential in situ and identify the resulting spectral changes. Often this is referred to as Modulation Excitation Spectroscopy (MES
Two-step acoustofluidic cancer cell enrichment
We have previously proposed and evaluated acoustophoresis for the enrichment of circulating tumor cells (CTC) and clusters thereof from the blood of patients with prostate cancer [1]. In that protocol, the cells were fixed and preserved in paraformaldehyde before processing and were thus non-viable. To enable future enrichment of also viable CTCs from patients, we have in this study investigated t
Transient buildup and decay of thermoacoustic streaming
We recently introduced the concept of thermoacoustic streaming in microchannels wherein a thermal field is generated inside an acoustic cavity. The result is a fast and controllable streaming for which the thermal energy is provided either by an LED light source [1], or a laser [2]. While in previous works we have measured this effect at steady state, we now present measurements of the build-up an
