Treatment of bacterial infections currently focuses on choosing an antibiotic that matches a pathogen's susceptibility, with less attention paid to the risk even susceptibility-matched treatments can fail as result resistance emerging in response treatment. Combining whole-genome sequencing 1113 pre- and posttreatment isolates machine-learning analysis 140,349 urinary tract 7365 wound infections, we found treatment-induced emergence could be predicted minimized at individual-patient level....
Active control over the shape, composition, and crystalline habit of nanocrystals has long been a goal. Various methods have shown to enable postsynthesis modification nanoparticles, including use Kirkendall effect, galvanic replacement, cation or anion exchange, all taking advantage enhanced solid-state diffusion on nanoscale. In these processes, however, alteration nanoparticles requires introduction new precursor materials. Here we show that for cesium lead halide perovskite reversible...
BackgroundAn Israeli national taskforce performed a multi-center clinical and analytical validation of seven serology assays to determine their utility limitations for SARS-CoV-2 diagnosis.MethodsSerology from Roche, Abbott, Diasorin, BioMerieux, Beckman-Coulter, Siemens, an in-house RBD ELISA were included. Negative samples 2391 individuals representative the population, 698 PCR positive patients, collected between March May 2020, analyzedFindingsImmunoassays sensitivities 81.5%-89.4%...
In recent years magic angle spinning-dynamic nuclear polarization (MAS-DNP) has developed as an excellent approach for boosting the sensitivity of solid-state NMR (ssNMR) spectroscopy, thereby enabling characterization challenging systems in biology and chemistry. Most commonly, MAS-DNP is based on use nitroxide biradicals polarizing agents. materials science, since nitroxides often limits signal enhancement to materials' surface subsurface layers, there need hyperpolarization approaches...
Abstract Beyond their substantial protection of individual vaccinees, it is hoped that the COVID-19 vaccines would reduce viral load in breakthrough infections thereby further suppress onward transmission. Here, analyzing positive SARS-CoV-2 test results following inoculation with BNT162b2 mRNA vaccine, we find reduced 4-fold for occurring 12-28 days after first dose vaccine. These loads hint to lower infectiousness, contributing vaccine impact on virus spread.
Metallic magnetic calorimeters (MMC) are calorimetric particle detectors, typically operated at temperatures below 100 mK, that make use of a paramagnetic temperature sensor to transform the rise upon absorption in detector into measurable flux change dc‐SQUID. During last years growing number groups has started develop MMC for wide variety applications, ranging from alpha‐, beta‐ and gamma‐spectrometry over spatially resolved detection accelerated molecule fragments arrays high resolution...
Interactions between charged and neutral self-assembled phospholipid membranes are well understood take into account temperature dependence. Yet, the manner in which structure of membrane is affected by was hardly studied. Here we study effect on thickness, area per lipid, volume lipid membranes. Two types were studied: composed lipids dipolar (neutral) that adsorbed divalent cations became charged. Small-angle X-ray scattering data demonstrate thickness decreases with temperature....
Background: National data on iodine status in Israel are lacking. Reliance iodine-depleted desalinated water, the absence of a salt iodization program, and reports increased use thyroid medication suggest that population's intake is likely inadequate. The aims this study were therefore to determine Israeli school-age children (SAC) pregnant women (PW) nationally representative sample obtained by novel approach using pre-discard urinalysis samples collected from centralized national...
Abstract Solid‐state NMR of low‐γ nuclides is often characterized by low sensitivity and significant spectral broadenings induced the quadrupolar chemical‐shift anisotropy interactions. Herein, we introduce an indirect acquisition method, termed PROgressive Saturation Proton Reservoir Under Spinning (PROSPRUS), which could facilitate ultra‐wideline spectra under magic‐angle spinning (MAS), in systems with a sufficiently long dipolar relaxation time, T 1D . PROSPRUS relies on generation...
We demonstrate a solution-based fabrication of centimeter-size free-standing films assembled from organic nanocrystals based on common dyes (perylene diimides, PDIs). These nanostructured exhibit good mechanical stability, and thermal robustness superior to most plastics, retaining the crystalline microstructure macroscopic shape upon heating up 250–300 °C. The show nonlinear optical response can be used as ultrafiltration membranes. functional materials small molecules alternative or...
Doped metal oxide materials are commonly used for applications in energy storage and conversion, such as batteries solid fuel cells. The knowledge of the electronic properties dopants their local environment is essential understanding effects doping on electrochemical properties. Using a combination X-ray absorption near-edge structure spectroscopy (XANES) experiment theoretical modeling we demonstrate that dilute (1 at. %) Mn-doped lithium titanate (Li
Non-typhoidal salmonellosis (NTS) is one of the most common foodborne diseases worldwide. In this study, we aimed to analyze trends in epidemiology NTS last decade Israel. Laboratory-confirmed cases at eight sentinel laboratories were reported Israel Sentinel Laboratory-Based Surveillance Network, integrated with serotype identification performed Salmonella National Reference Laboratory Ministry Health. The decrease incidence since 1999 continued between 2010 and 2014 (16.1 per 100,000 2014)...
Nuclear magnetic resonance (NMR) is a well-established technique, to study crystalline and amorphous solids, that provides rich structural dynamical insights. Many solids NMR experiments, however, are challenged by sensitivity considerations, which demand the use of optimized data acquisition protocols. When inhomogeneous broadenings dominate lineshapes, as often case when dealing with quadrupolar nuclei, application multiple echoes means Carr-Purcell Meiboom-Gill (CPMG) sequence variants...
Techniques for enhancing the signals arising from low-γ, insensitive (I) nuclei are central to solid-state nuclear magnetic resonance. One of leading and best-established methods sensitize these unreceptive species is Hartmann–Hahn cross polarization (HH-CP), a transfer mechanism often executed under MAS. Herein, we explore possibility utilizing 1H dipolar order created via adiabatic demagnetization in rotating frame (ADRF), enhance spins It found that an efficient ADRF-CPMAS not only...
