Non-destructive quantitative analysis of melt inclusions in extraterrestrial samples: Case study of chassignite via nanoscale X-ray computed tomography.

Estimation of the composition of planetary rocks and minerals is crucial for understanding their formation processes. In this study, we present the application of X-ray nano-computed tomography (nano-XCT) for non-destructive 3D phase analysis and estimation of phase abundances in rare martian meteorite samples, specifically chassignite Northwest Africa (NWA) 2737. We determined the most suitable laser power for minimizing artifacts and maximizing phase contrast.

"It means almost forgetting that you've got a disease": An OMERACT study to define independence in the context of rheumatoid arthritis remission from the patient perspective.

Aims: Our previous work identified pain, fatigue, and independence as missing from the ACR/EULAR rheumatoid arthritis (RA) remission criteria from the patient perspective. Validated measures exist for pain and fatigue, but not for independence. As a first step towards developing such a measure, this study aimed to understand 'Independence' in the context of RA remission from the patient perspective.

Disease-specific definitions of new bone formation on spine radiographs: a systematic literature review.

Objectives: We aimed to explore the radiographic definitions of types of New Bone formation (NBF) by focusing on the terminology, description and location of the findings.

Methods: Three systematic literature reviews were conducted in parallel to identify the radiographic spinal NBF definitions for spondyloarthritis (SpA), Diffuse Idiopathic Skeletal Hyperostosis (DISH) and Osteorathritis (OA). Study characteristics and definitions were extracted independently by two reviewers.

The potential of therapeutic hyperthermia to eradicate Staphylococcus aureus bacteria; an in vitro study.

Staphylococcus aureus is one of the most common infectious agents, causing morbidity and mortality worldwide. Most pathogenic bacteria are classified in the group of mesophilic bacteria and the optimal growth temperature of these bacteria changes between 33 and 41 °C. Increased temperature can inhibit bacterial growth and mobility, which in turn, can trigger autolysis and cause cell wall damage.

In Vitro and Ex Vivo Investigation of the Antibacterial Effects of Methylene Blue against Methicillin-Resistant .

Methylene blue (MB) is a water-soluble dye that has a number of medical applications. Methicillin-resistant (MRSA) was selected as a subject for research due to the numerous serious clinical diseases it might cause and because there is a significant global resistance challenge. Our main goal was to determine and analyze the antibacterial effects of MB against both in vitro and ex vivo to enhance treatment options.

Effect of material properties on emotion: a virtual reality study.

Introduction: Designers know that part of the appreciation of a product comes from the properties of its materials. These materials define the object's appearance and produce emotional reactions that can influence the act of purchase. Although known and observed as important, the affective level of a material remains difficult to assess.

Multiple Rounds of Random Mutagenesis and Selection in Result in Substantial Increases in REE Binding Capacity.

Rare earth elements (REE) are essential ingredients in many modern technologies, yet their purification remains either environmentally harmful or economically unviable. Adsorption, or biosorption, of REE onto bacterial cell membranes offers a sustainable alternative to traditional solvent extraction methods. But in order for biosorption-based REE purification to compete economically, the capacity and specificity of biosorption sites must be enhanced.

Genomic characterization of rare earth binding by Shewanella oneidensis.

Rare earth elements (REE) are essential ingredients of sustainable energy technologies, but separation of individual REE is one of the hardest problems in chemistry today. Biosorption, where molecules adsorb to the surface of biological materials, offers a sustainable alternative to environmentally harmful solvent extractions currently used for separation of rare earth elements (REE). The REE-biosorption capability of some microorganisms allows for REE separations that, under specialized conditions, are already competitive with solvent extractions, suggesting that genetic engineering could allow it to leapfrog existing technologies.

Phases in fine volcanic ash.

Volcanic ash emissions impact atmospheric processes, depositional ecosystems, human health, and global climate. These effects are sensitive to the size and composition of the ash; however, datasets describing the constituent phases over size ranges relevant for atmospheric transport and widely distributed impacts are practically nonexistent. Here, we present results of X-ray diffraction measurements on size-separated fractions of 40 ash samples from VEI 2-6 eruptions.

Oceanic intraplate explosive eruptions fed directly from the mantle.

Constraining the volatile content of magmas is critical to our understanding of eruptive processes and their deep Earth cycling essential to planetary habitability [R. Dasgupta, M. M.

[Analysis of Mycobacterium tuberculosis Complex Strains Isolated from the Samples of Patients Living in Northern Syria].

Tuberculosis causes serious mortality and morbidity worldwide each year. A lot of effort and money is spent for the diagnosis and treatment of tuberculosis all over the world. The importance that countries give to health policies and public health is inversely proportional to the incidence of tuberculosis and multidrug resistant tuberculosis.

The evolution of the Galápagos mantle plume.

The lavas associated with mantle plumes may sample domains throughout Earth's mantle and probe its dynamics. However, plume studies are often only able to take snapshots in time, usually of the most recent plume activity, leaving the chemical and geodynamic evolution of major convective upwellings in Earth's mantle poorly constrained. Here, we report the geodynamically key information of how the lithology and density of a plume change from plume head phase to tail.

Deep magma storage during the 2021 La Palma eruption.

The 2021 La Palma eruption provided an unpreceded opportunity to test the relationship between earthquake hypocenters and the location of magma reservoirs. We performed density measurements on CO-rich fluid inclusions (FIs) hosted in olivine crystals that are highly sensitive to pressure via calibrated Raman spectroscopy. This technique can revolutionize our knowledge of magma storage and transport during an ongoing eruption, given that it can produce precise magma storage depth constraints in near real time with minimal sample preparation.

Traditional and Disease-Specific Risk Factors for Cardiovascular Events in Antineutrophil Cytoplasmic Antibody-Associated Vasculitis: A Multinational Retrospective Study.

Objective: To investigate the occurrence of cardiovascular events (CVEs) in a large cohort of patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) across the European Union, China, Turkey, Russia, the United Kingdom, and the USA.

Methods: Patients with a definite diagnosis of AAV who were followed for ≥ 3 months and had sufficient documentation were included. Data on myocardial infarction (MI) and stroke were collected retrospectively from tertiary vasculitis centers.

Defining independence: A scoping review by the OMERACT patient perspective of remission in rheumatoid arthritis group.

Aims: The Outcome Measures in Rheumatology Trials (OMERACT) Remission in Rheumatoid Arthritis (RA) patient perspective working group has previously found that patients prioritised independence, pain, and fatigue as key domains of remission in RA. However, there is currently no clear definition of independence. Consequently, this scoping review aimed to explore how independence is represented in the RA literature.

Musculoskeletal Point-of-Care Ultrasonography Training Among Canadian Postgraduate Rheumatology Programs.

Objective: This study aimed to assess the current state of musculoskeletal point-of-care ultrasonography training among the rheumatology postgraduate programs in Canada and explored the interest in developing a national curriculum.

Method: A Canadian survey was developed by academic rheumatologists including point-of-care ultrasonography experts and point-of-care ultrasonography non-users. Across Canada, all 15 adult and 3 pediatric rheumatology English and French postgraduate programs were surveyed via Survey Monkey with a standardized questionnaire.

Factors affecting patient satisfaction with outpatient rheumatology phone visits during the COVID-19 pandemic.

The aim was to evaluate patient satisfaction with virtual care, and identify factors associated with level of satisfaction. Surveys were mailed to all patients who had a phone visit at The Ottawa Hospital Rheumatology division. Patients' satisfaction with various aspects of the phone visits was assessed on a 5-point scale and analyzed according to demographic variables using chi-square and regression analyses.

Healthcare personnel's attitude and coverage about tetanus vaccination in Turkey: a multicenter study.

The tetanus vaccine is not routinely given to Turkish adults. Protective tetanus immunity decreases with age. Health-care personnel (HCPs), who are role models in the field of health, are a target group in order to achieve a higher rate of tetanus vaccination in the community.

Impact of diabetes mellitus on urinary continence after holmium laser enucleation of the prostate due to lower urinary tract symptoms: a retrospective study.

Introduction: Diabetes mellitus (DM) is known as a risk factor of stress urinary incontinence after Holmium laser enucleation of the prostate (HoLEP). We aimed to compare the postoperative continence status of patients with and without DM, after HoLEP surgery.

Material And Methods: A total of 214 patients who underwent HoLEP between January 2017 and January 2020 were retrospectively assessed.

Serpentinite-derived slab fluids control the oxidation state of the subarc mantle.

Recent geochemical evidence confirms the oxidized nature of arc magmas, but the underlying processes that regulate the redox state of the subarc mantle remain yet to be determined. We established a link between deep subduction-related fluids derived from dehydration of serpentinite ± altered oceanic crust (AOC) using B isotopes and B/Nb as fluid proxies, and the oxidized nature of arc magmas as indicated by Cu enrichment during magma evolution and V/Yb. Our results suggest that arc magmas derived from source regions influenced by a greater serpentinite (±AOC) fluid component record higher oxygen fugacity.

High He/He in central Panama reveals a distal connection to the Galápagos plume.

It is well established that mantle plumes are the main conduits for upwelling geochemically enriched material from Earth's deep interior. The fashion and extent to which lateral flow processes at shallow depths may disperse enriched mantle material far (>1,000 km) from vertical plume conduits, however, remain poorly constrained. Here, we report He and C isotope data from 65 hydrothermal fluids from the southern Central America Margin (CAM) which reveal strikingly high He/He (up to 8.

Generation of a Gluconobacter oxydans knockout collection for improved extraction of rare earth elements.

Bioleaching of rare earth elements (REEs), using microorganisms such as Gluconobacter oxydans, offers a sustainable alternative to environmentally harmful thermochemical extraction, but is currently not very efficient. Here, we generate a whole-genome knockout collection of single-gene transposon disruption mutants for G. oxydans B58, to identify genes affecting the efficacy of REE bioleaching.

Identification of Recent Tuberculosis Exposure Using QuantiFERON-TB Gold Plus, a Multicenter Study.

We investigated whether the difference of antigen tube 2 (TB2) minus antigen tube 1 (TB1) (TB2-TB1) of the QuantiFERON-TB gold plus test, which has been postulated as a surrogate for the CD8 T-cell response, could be useful in identifying recent tuberculosis (TB) exposure. We looked at the interferon gamma (IFN-γ) responses and differences in TB2 and TB1 tubes for 686 adults with QFT-plus positive test results. These results were compared among groups with high (368 TB contacts), low (229 patients with immune-mediated inflammatory diseases [IMID]), and indeterminate (89 asylum seekers or people from abroad [ASPFA]) risks of recent TB exposure.
