Previous studies have demonstrated that in admixed populations, West African ancestry is associated with an increased prevalence of systemic lupus erythematosus (SLE). In the current study, the effect of Amerindian ancestry in SLE was examined in an admixed population in Argentina. The Argentine population is predominantly European with approximately 20% Amerindian admixture, and a very small (<2%

OBJECTIVES: The present study tested the hypothesis that treatment with human recombinant immunoglobulin G1 (IgG1) antibodies against a specific oxidized low-density lipoprotein (oxLDL) epitope will induce regression of existing atherosclerotic lesions in LDL receptor-deficient mice expressing apolipoprotein B-100 (apoB-100) (Apobec-1(-/-)/LDLR(-/-)). BACKGROUND: Oxidized LDL plays an essential ro

The dysregulated immune response and inflammation resulting in severe COVID-19 are still incompletely understood. Having recently determined that aberrant death-ligand-induced cell death can cause lethal inflammation, we hypothesized that this process might also cause or contribute to inflammatory disease and lung failure following SARS-CoV-2 infection. To test this hypothesis, we developed a nove

IMPORTANCE: In patients with clinically node-negative (cN0) breast cancer and 1 or 2 sentinel lymph node (SLN) macrometastases, omitting completion axillary lymph node dissection (CALND) is standard. High nodal burden (≥4 axillary nodal metastases) is an indication for intensified treatment in luminal breast cancer; hence, abstaining from CALND may result in undertreatment.OBJECTIVE: To develop a

Background: Combined CDK4/6 inhibitor (CDK4/6i) and endocrine therapy significantly improve the outcome of patients with advanced estrogen receptor-positive (ER+) breast cancer. However, resistance to this treatment and disease progression remains a major clinical challenge. High expression of the receptor tyrosine kinase REarranged during Transfection (RET) has been associated with resistance to

BackgroundThe lack of effective screening methods for the detection of ovarian cancer leads to late diagnosis and poor outcomes. High-grade serous ovarian carcinoma (HGSC) is strongly dominated by copy number alterations (CNAs), resulting from underlying mutational processes. Several studies have reported the detection of ovarian carcinoma-derived somatic mutations in cervical samples, uterine lav

We aim to characterize high-velocity (HiVel) stars in the solar vicinity both chemically and kinematically using the fourth data release of the RAdial Velocity Experiment (RAVE). We used a sample of 57 HiVel stars with Galactic rest-frame velocities larger than 275 km s(-1). With 6D position and velocity information, we integrated the orbits of the HiVel stars and found that, on average, they reac

BACKGROUND: HYPO-RT-PC is a phase 3 trial comparing ultra-hypofractionated and conventionally fractionated radiotherapy in intermediate-to-high-risk localised prostate cancer. This 10-year update reports long-term efficacy and toxicity outcomes.METHODS: In this open-label, randomised, phase 3, non-inferiority trial done in ten centres in Sweden and two in Denmark, we recruited men aged 75 years or

Background: Ambulatory oxygen therapy can be used to treat exertional hypoxaemia during daily life activities in people with fibrotic interstitial lung disease (ILD). However, evidence for its efficacy is scarce. This trial aimed to compare the effects of ambulatory oxygen with ambulatory air on physical activity in daily life over 6 months in people with fibrotic ILD and isolated exertional hypox

Background: Postoperative lymph node irradiation can affect shoulder morbidity in breast cancer patients, yet widely accepted dose-volume constraints for the shoulder joint are lacking. The SENOMAC trial randomized patients with breast cancer and 1–2 sentinel lymph node (SLN) macrometastases to axillary lymph node dissection (ALND) or SLN biopsy only. We aimed to analyze the association between th

Introduction: Synovial fibroblasts (S-Fib) are recognized as key drivers of joint inflammation in adult arthritis. Moreover, data are limited on the processes driving monocyte activation in oligoarticular juvenile idiopathic arthritis (oJIA). Therefore, we aimed to explore if S-Fib from patients with oJIA induce monocyte activation. Methods: S-Fib were isolated from the synovial fluid (SF) of n =

Nature provides us with a vast source of inspiration. However, given industrial designers' open-mindedness and inquisitiveness, a surprisingly limited set of nature-derived symbols continues to be popular in this creative discipline. Rather than designing products mimicking nature, it is probably more rewarding designing them based on the natural principles leading to its growth and form. However,

Context: Polymorphisms in genes involved in regulation, biosynthesis, metabolism, and actions of testicular sex hormones may influence hormone balance and phenotype of aging men. Objective: We investigated the relationships between polymorphisms in genes related to pituitary-testicular endocrine function and health status. Design and Setting: Using cross-sectional baseline data, we conducted a mul

This article aims to estimate the prevalence of SOX13 antibodies in Swedish patients with type 1 diabetes and healthy controls. The patients (n = 102; median age 35 years [range, 9-89]) were newly diagnosed with type 1 diabetes in a defined area in southern Sweden during 1995-1998. Islet cell antibodies (ICA) were analyzed with immunofluorescence, while glutamic acid decarboxylase antibodies (GADA

Cobalt silicide has emerged as a leading contact material in silicon technology due to its low resistivity, high stability and small lattice mismatch. In this study, 0.2-0.4 mu m thick Co films were deposited on Si(100) wafers by RF magnetron sputtering at room temperature, and annealed at temperatures from 600 to 900 degrees C in vacuum. As-deposited and annealed samples were characterized by Rut

Although targeting oncogenic mutations in the BRAF serine/threonine kinase with small molecule inhibitors can lead to significant clinical responses in melanoma, it fails to eradicate tumors in nearly all patients. Successful therapy will be aided by identification of intrinsic mechanisms that protect tumor cells from death. Here, we used a bioinformatics approach to identify drug-able, "driver" o

Local environmental and ecological conditions are commonly expected to result in local adaptation, although there are few examples of variation in phenotypic selection across continent-wide spatial scales. We collected standardized data on selection with respect to the highly variable plumage coloration of pied flycatcher (Ficedula hypoleucaPall.) males from 17 populations across the species' bree

Pb-based perovskite absorbers with organic (i.e., CH3NH3+) and inorganic (i.e., Cs+) cations and a halide composition of 75% Br and 25% I are investigated with x-ray photoelectron spectroscopy while submitted to environmental stress factors to study their stability. Changes in chemical properties of the absorbers were monitored in ultra-high vacuum and under simulated solar, as well as, x-ray irra
