The risk among asphalt workers of developing adverse health effects may increase due to their occupational exposure. One area of special concern arises when rubber granules are mixed into bitumen to enhance asphalt properties. This research characterizes and compares bitumen and rubber bitumen regarding the emissions of and workers' exposure to particulates, polycyclic aromatic hydrocarbons (PAHs)

Introduction: Long-term oxygen therapy (LTOT) improves survival and may reduce hospital admissions in patients with chronic obstructive pulmonary disease (COPD) and severe hypoxemia, but the impact of daily duration of LTOT on hospitalization rate is unknown. We aimed to estimate the association between the daily duration of LTOT (24 vs 15 h/d) and hospital admissions in patients with LTOT due to

Ear acupuncture is used as a non-pharmacological complement in psychiatric and addiction care to reduce anxiety, depression and insomnia. The aim of this study was to describe health care professionals' perceptions of giving ear acupuncture in different psychiatric settings. Twenty-four professionals providing ear acupuncture to patients with a variety of psychiatric symptoms and/or addiction were

Herein is described the switchable fluorescence response of poly(methyl methacrylate) (PMMA) brushes. Chain end fluorescein labeled PMMA brushes are prepared by combining surface-initiated atom transfer radical polymerization (SI-ATRP) with a copper-catalyzed alkyne-azide cycloaddition (CuAAC) click reaction. Successful attachment of fluorescein is confirmed by measuring fluorescence of the as-pre

Studies have shown that offenders have impaired cognitive abilities yet it is unclear if cognitive dysfunction per se contributes to aggressive antisocial behaviors. Our aims were to (1) determine associations between cognitive functioning and different forms of aggressive antisocial behaviors, (2) describe prevalence of, and covariates to, uneven intellectual profiles, and (3) investigate associa

Background: Head and Neck Squamous Cell Carcinoma (HNSCC) tumors are often resistant to therapies. Therefore searching for predictive markers and new targets for treatment in clinically relevant in vitro tumor models is essential. Five HNSCC-derived cell lines were used to assess the effect of 3D culturing compared to 2D monolayers in terms of cell proliferation, response to anti-cancer therapy as

Self-assembled, atomic diffusion controlled growth of InN quantum dots was realized on the side facets of dislocation-free and c-oriented GaN nanowires having a hexagonal cross-section. The nanowires were synthesized by selective area metal organic vapor phase epitaxy. A 3 Å thick InN wetting layer was observed after growth, on top of which the InN quantum dots formed, indicating self-assembly in

Furthering knowledge of the subset of incarcerated partner violent offenders distinguished by aggression, anger, and hostility is relevant, as these offenders are guilty of the more severe kinds of intimate partner violence (IPV). Our aim was to identify groups with different patterns of IPV among convicted young Swedish male offenders, using data from the Development of Aggressive Antisocial Beha

Long-term oxygen therapy (LTOT) improves prognosis in patients with COPD and chronic severe hypoxemia. The efficacy in moderate hypoxemia (tension of arterial oxygen; on air, 7.4−8.0 kPa) was questioned by a recent large trial. We reviewed the evidence to date (five randomized trials; 1,191 participants, all with COPD). Based on the current evidence, the survival time may be improved in patients w

Background: Incision complications (IC) have a significant impact on procedure-related morbidity after lower-limb revascularization. One of the most studied IC is surgical site infection (SSI). Reporting these complications in a uniform way is crucial to evaluate treatment approaches. The aim of this study was to propose a comprehensive classification of IC and apply it to compare SSI with other I

The number of children who were born after their parents were diagnosed with central nervous system (CNS) tumor is increasing, but it remains largely unknown regarding the academic performance of these children. We aimed to investigate whether children of survivors with childhood or adolescent CNS tumor were associated with poor academic performance. Children of survivors of CNS tumor were identif

Microplastics have recently become a growing environmental issue, whereas the smaller fractions, nanoplastics, have received less attention. Due to their small size, nanoplastics may affect organisms differently and potentially more severely than larger microplastics. In natural environments nanoplastics also interact with organic material and form larger aggregates, which may, potentially, reduce

Objectives To investigate changes in bone mineral density (BMD) in patients with early rheumatoid arthritis (RA) over a 10-year period. Methods Consecutive patients with early RA (symptom duration <12 months) were followed according to a structured programme and examined with dual-energy X-ray absorptiometry (DXA) at inclusion and after 2, 5 and 10 years. Mean Z-scores over the study period were e

Canesin et al. describe a role and mechanism for labile heme as a key player in regulating gene expression to promote carcinogenesis via binding to G-quadruplex in the c-MYC promoter. Hemopexin, a heme scavenger, may be used as a strategy to block progression of cancer.

Introduction Breathlessness is common in the general population and associated with poorer health. Prevalence, frequencies and overlap of underlying contributing conditions among individuals reporting breathlessness in the general population is unclear. The aim was to evaluate which conditions that were prevalent, overlapping and associated with breathlessness in a middle-aged general population.

Integration of disaster risk reduction (DRR) and climate change adaptation (CCA) is widely recognized as a solution for reducing the risk and impacts of disasters. However, successful integration seems elusive, and the two goals continue to function in isolation and in parallel. This article provides empirical insights into the perceived effects of separating government institutions for DRR and CC

Lymphotoxin β-receptor (LTβR) signalling promotes lymphoid neogenesis and the development of tertiary lymphoid structures1,2, which are associated with severe chronic inflammatory diseases that span several organ systems3-6. How LTβR signalling drives chronic tissue damage particularly in the lung, the mechanism(s) that regulate this process, and whether LTβR blockade might be of therapeutic value

Using observational data to assess the treatment effects on outcomes of kidney transplantation relative to dialysis for patients on renal replacement therapy is challenging due to the non-random selection into treatment. This study applied the propensity score weighting approach in order to address the treatment selection bias of kidney transplantation on survival time compared with dialysis for p

The advent of microfluidics in the 1990s promised a revolution in multiple industries from healthcare to chemical processing. Deterministic lateral displacement (DLD) is a continuous-flow microfluidic particle separation method discovered in 2004 that has been applied successfully and widely to the separation of blood cells, yeast, spores, bacteria, viruses, DNA, droplets, and more. Deterministic
