Clinically observed deletions in SARS-CoV-2 Nsp1 affect its stability and ability to inhibit translation

Nonstructural protein 1 (Nsp1) of SARS-CoV-2 inhibits host cell translation through an interaction between its C-terminal domain and the 40S ribosome. The N-terminal domain (NTD) of Nsp1 is a target of recurring deletions, some of which are associated with altered COVID-19 disease progression. Here, we characterize the efficiency of translational inhibition by clinically observed Nsp1 deletion var

Musculoskeletal pain and its association with health status, maturity, and sports performance in adolescent sport school students : a 2-year follow-up

Background: Musculoskeletal pain and its risk factors are rarely assessed in studies on adolescent athletes. The aim was to identify risk factors at baseline that were associated with the persistence or development of musculoskeletal pain at a two-year follow-up in adolescent sport school students, and to study cross-sectional associations at follow-up between musculoskeletal pain and sports perfo

Exploring Climate Change Perspectives. An Analysis of Undergraduate Students' Place-Based Attachment in Appalachia, USA

Despite global scientific consensus, climate change is a highly controversial and politicized issue in the United States. Grounded in two quantitative survey iterations with approximately 446 responses, 28 semi-structured interviews, and 4 focus groups with 60 undergraduate students from six state universities in the Appalachian region, this five-year study explores the role of place-based attachm

Clustering of comorbidities and associated outcomes in people with osteoarthritis - A UK Clinical Practice Research Datalink study

Objective: To examine the clusters of chronic conditions present in people with osteoarthritis and the associated risk factors and health outcomes. Methods: Clinical Practice Research Datalink (CPRD) GOLD was used to identify people diagnosed with incident osteoarthritis (n = 221,807) between 1997 and 2017 and age (±2 years), gender, and practice matched controls (no osteoarthritis, n = 221,807) f

Why Did the Origenist Controversy Begin? Re-thinking the Standard Narratives

The Origenist controversy at the end of the fourth century was largely played out within a monastic context, and had, moreover, an immediate and extensive impact on the movement. In spite of this, studies of the controversy and its causes have mainly focused on the dogmatic issues foregrounded in the controversy, neglecting the more fundamental issues about why the legacy of Origen was important,

Per- and polyfluoroalkyl substances (PFAS) and male reproductive function in young adulthood; a cross-sectional study

Background: Per- and polyfluoroalkyl substances (PFAS) are a large family of persistent industrial chemicals with endocrine disrupting properties. Objectives: To examine biomarkers of reproductive function in young adult males according to current environmental exposure to single and combined PFAS. Methods: The study population consisted of young men (n = 1041, age 18–21) from the Fetal Programmin

Investigation on thermal performance of electric heaters with nanofluids

This work aims to analyze thermal performance for an electric heater filled with different nanofluids, including SiO2-water nanofluid, Fe3O4-water nanofluid, and Cu-water nanofluid. The effect of nanoparticle concentration (0.1–2.0 wt%) is also discussed. Results indicate that Cu-water nanofluids show better heat transfer performance than the other nanofluids. The highest heating efficiency for th

Maximum detection distances for gamma emitting point sources in mobile gamma spectrometry

In this study an algorithm was developed for calculating maximum detectable distance (MDD) for mobile gamma-ray detection of lost sources in-situ for some common mobile spectrometer systems and gamma sources (137Cs and 60Co). The MDD is a function of detector efficiency, vehicle speed, acquisition time interval, radiation background level and accepted frequency of false alarms. To test its accurac

A di‑iron(III) μ-oxido complex as catalyst precursor in the oxidation of alkanes and alkenes

The oxido-bridged diiron(III) complex [Fe2(μ-O)(μ-OAc)(DPEAMP)2](OCH3) (1), based on a new unsymmetrical ligand with an N4O donor set, viz. [2-((bis(pyridin-2-ylmethyl)amino)methyl)-6-((ethylamino)methyl)-4-methylphenol (HDPEAMP)], has been prepared and characterized by spectroscopic methods and X-ray crystallography. The crystal structure of the complex reveals that each Fe(III) ion is coordinate

A plant-wide model describing GHG emissions and nutrient recovery options for water resource recovery facilities

In this study, a plant-wide model describing the fate of C, N and P compounds, upgraded to account for (on-site/off-site) greenhouse gas (GHG) emissions, was implemented within the International Water Association (IWA) Benchmarking Simulation Model No. 2 (BSM2) framework. The proposed approach includes the main biological N2O production pathways and mechanistically describes CO2 (biogenic/non-biog

Hospitalisations with infectious disease diagnoses in somatic healthcare between 1998 and 2019 : A nationwide, register-based study in Swedish adults

Background: Several studies indicate increasing hospitalisation rates for specific infectious diseases (IDs). Studies describing the entire ID spectrum are scarcer. Our aim was to describe hospital use with ID diagnoses in Swedish adults from 1998 to 2019. Methods: All four-position codes in ICD-10 were reclassified as ID or non-ID diagnoses. Using data from the National Patient Register, age-stan

Hydrogels derived from decellularized liver tissue support the growth and differentiation of cholangiocyte organoids

Human cholangiocyte organoids are promising for regenerative medicine applications, such as repair of damaged bile ducts. However, organoids are typically cultured in mouse tumor-derived basement membrane extracts (BME), which is poorly defined, highly variable and limits the direct clinical applications of organoids in patients. Extracellular matrix (ECM)-derived hydrogels prepared from decellula

Numerical investigation of railway subgrade stiffening : Critical speed and free-field vibrations

For a train speed close to the speed of elastic waves in the soil, often referred to as “critical speed”, largely elevated vibration responses occur. This can be a practical problem for soft soil sites, where the phenomenon may cause excessive vibrations in the track and also at distances far from the track. To ensure the running safety of the train, the long-term quality of the track and to reduc

Luminescence characteristics of Scandinavian quartz, their connection to bedrock provenance and influence on dating results

The success of optically stimulated luminescence (OSL) dating relies to a large extent on suitable characteristics of the analysed mineral, in this case quartz. Previous OSL dating of Quaternary sediments in Scandinavia has shown that quartz characteristics vary widely across the region, resulting in dating studies with varied success. The aim of this study is to provide an overview of quartz lumi

Antipsychotic Use During Pregnancy and Risk for Gestational Diabetes : A National Register-Based Cohort Study in Sweden

Objective: We aimed to study whether antipsychotic use during pregnancy is associated with gestational diabetes. Methods: This was a Swedish national register‐based cohort study on the Medical Birth Register and the Prescribed Drug Register including all 1,307,487 singleton births between July 2006 and December 2017. Antipsychotics were divided into first-generation antipsychotics (n = 728), high-

Experimental study on combustion and flow resistance characteristics of an afterburner with air-cooled bluff-body flameholder

In the afterburner assembled with an air-cooled bluff-body flameholder, cooling air is directly injected into the recirculation zone behind the bluff-body, which can reduce the local temperature and increase the oxygen concentration of the gas mixture in the wake of the bluff-body, thereby affecting the total pressure loss and combustion characteristics. To better understand the flow and combustio
