Non-parametric deconvolution using Bézier curves for quantification of cerebral perfusion in dynamic susceptibility contrast MRI
Objective Deconvolution is an ill-posed inverse problem that tends to yield non-physiological residue functions R(t) indynamic susceptibility contrast magnetic resonance imaging (DSC-MRI). In this study, the use of Bézier curves is proposedfor obtaining physiologically reasonable residue functions in perfusion MRI.Materials and methods Cubic Bézier curves were employed, ensuring R(0)=1, bounded-in
Myocardial injury biomarkers at point of care for early identification of primary graft dysfunction after heart transplantation
INTRODUCTION: Primary graft dysfunction (PGD) is a leading cause of 30-day mortality following heart transplantation, and early intervention in PGD may correlate to improved survival. Our analysis aimed to determine the feasibility of measuring cardiac biomarkers from the donor heart in the early phase for use as a predictor of PGD.METHODS: Blood samples from the coronary sinus were obtained at th
Measurements of Strong-Interaction Effects in Kaonic-Helium Isotopes at Sub-eV Precision with X-Ray Microcalorimeters
We have measured the 3d→2p transition x rays of kaonic 3He and 4He atoms using superconducting transition-edge-sensor microcalorimeters with an energy resolution better than 6 eV (FWHM). We determined the energies to be 6224.5±0.4(stat)±0.2(syst) eV and 6463.7±0.3(stat)±0.1(syst) eV, and widths to be 2.5±1.0(stat)±0.4(syst) eV and 1.0±0.6(stat)±0.3(stat) eV, for kaonic 3He and 4He, respectively.
Production of Λ and KS0 in jets in p–Pb collisions at sNN=5.02 TeV and pp collisions at s=7 TeV
The production of Λ baryons and KS0 mesons (V0 particles) was measured in p–Pb collisions at sNN=5.02 TeV and pp collisions at s=7 TeV with ALICE at the LHC. The production of these strange particles is studied separately for particles associated with hard scatterings and the underlying event to shed light on the baryon-to-meson ratio enhancement observed at intermediate transverse momentum (pT) i
Feasibility of EBUS-TBNA for histopathological and molecular diagnostics of NSCLC-A retrospective single-center experience
Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a minimally invasive bronchoscopic procedure, well established as a diagnostic modality of first choice for diagnosis and staging of non-small cell lung cancer (NSCLC). The therapeutic decisions for advanced NSCLC require comprehensive profiling of actionable mutations, which is currently considered to be an essential
Challenges with disaster mortality data and measuring progress towards the implementation of the Sendai Framework
Disasters exact a heavy toll globally. However, the degree to which we can accurately quantify their impact, in particular mortality, remains challenging. It is critical to ensure that disaster data reliably reflects the scale, type, and distribution of disaster impacts given the role of data in: (1) risk assessments; (2) developing disaster risk management programs; (3) determining the resources
Storage, patterns, and environmental controls of soil organic carbon stocks in the permafrost regions of the Northern Hemisphere
Large stocks of soil organic carbon (SOC) accumulated in the Northern Hemisphere permafrost regions may be vulnerable to climatic warming, but global estimates of SOC distribution and magnitude in permafrost regions still have large uncertainties. Based on multiple high-resolution environmental variables and a compiled soil sample dataset (>3000 soil profiles), we used machine-learning methods to
Climate governance at the fringes : Peri-urban flooding drivers and responses
There is a large body of scientific evidence on the climate crisis and flooding in urban areas. Extreme weather events are producing extensive property damage and loss of life and require new modes of flood governance. However, the climate crisis does not stop at the city limits: peri-urban areas have related but distinct flood challenges due to land use change, regulation, perceptions, and capaci
Transaminase-Catalyzed Racemization with Potential for Dynamic Kinetic Resolutions
Dynamic kinetic resolution (DKR) reactions in which a stereoselective enzyme and a racemization step are coupled in one pot would represent powerful tools for the production of enantiopure amines through enantioconvergence of racemates. The exploitation of DKR strategies is currently hampered by the lack of effective, enzyme-compatible and scalable racemization strategies for amines. In the presen
Saving the best for last? : Old age retirement among the Urban middle classes in Leiden and Regensburg (c. 1650- c. 1800)
In pre-industrial Europe, many thousands of ‘middle-class’ individuals retired by purchasing a corrody: a contract allowing them life-long food and lodging, usually by spending their remaining years in a hospital. Given that people usually struggle to prepare for the later stages of life, this article asks whether corrodies were priced in line with the market. We study institutions that specialize
Control Mechanisms Towards Project Success
This study, based on a systematic literature review, aims to identify and analyze selected control mechanisms when project success criteria operationalize. The main theoretical contribution of this study involves identifying the dimension of control mechanisms in success criteria operationalization. The most easily identified control mechanisms in the data material were output control mechanisms,

The use of collected memories : Challenges in differences
During 2020 archives and museums collected both personal memories and artifacts related to the corona outbreak. The aim was to document the unique situation and to save memories for the future. How can the experiences from this year be used in cooperation between academia and archives and museums?
[P]ers[on]a mis[ce]lanea : Works of Manuel Ponce by Bertrand Chavarría-Aldrete
This release brings together some of Ponce’s finest guitar works, carefully selected and sensitively performed by Bertrand Chavarría-Aldrete. The album opens with a Preludio written not long after Ponce arrived in Paris, characterised by modal and whole tone inflections that lend the piece an impressionistic quality. The release also includes the later set of Seis preludios cortos (‘Six short prel
The effect of tezepelumab on airway hyperresponsiveness to mannitol in asthma (UPSTREAM)
RATIONALE AND OBJECTIVES: Thymic stromal lymphopoietin (TSLP), an epithelial upstream cytokine, initiates production of type-2 (T2) cytokines with eosinophilia and possibly airway hyperresponsiveness (AHR) in asthma.This study aimed to determine whether tezepelumab (a human monoclonal antibody targeting TSLP) decreases AHR and airway inflammation in patients with symptomatic asthma on maintenance
Gatifloxacin induces S and G2-phase cell cycle arrest in pancreatic cancer cells via p21/p27/p53
Pancreatic cancer, despite being the most dreadful among gastrointestinal cancers, is poorly diagnosed, and further, the situation has been aggravated owing to acquired drug resistance against the single known drug therapy. While previous studies have highlighted the growth inhibitory effects of older generation fluoroquinolones, the current study aims to evaluate the growth inhibitory effects of

Factors affecting pandemic biosecurity behaviors of international travelers : Moderating roles of gender, age, and travel frequency
Research undertaken during the COVID‐19 pandemic has identified a number of significant factors that affect international travelers’ biosecurity behavior. Tourists’ age and gender as well as travel frequency have been found to have significant impacts on consumers’ non‐pharmaceutical intervention practices. However, despite the importance of age, gender, and travel frequency, such studies have ove
