Constraining the climate impact of particulate brown carbon (BrC) will require identification of formation mechanisms and isolation of its different components to allow for source apportionment. For fresh combustion aerosols, the light absorption characteristics and the Absorption Ångstrom Exponent (AAE) are principally controlled by the combustion conditions in which the particles formed and evol

Some secreted cysteine protease inhibitors of the cystatin family appear to affect intracellular proteolysis and growth of human cells, as a result of internalization. Here, we studied the effects of external addition of the most abundant human cystatin, cystatin C, on viability and proliferation of cancer cells in culture. A dose-dependent decrease in viable cells was seen for A375 melanoma, MCF-

Thin, stable and inert dielectric spacers are essential for manufacturing electronic devices based on 2D materials. However, direct synthesis on top of 2D materials is difficult due to their inert nature. In this work, we studied how an electron beam induces fragmentation of borazine and enables spatially confined synthesis of amorphous-BNx on graphene at room temperature. Using a combination of X

AIMS: Inflammation plays an important role in cardiovascular disease (CVD) development. The NOD-like receptor protein-3 (NLRP3) inflammasome contributes to the development of atherosclerosis in animal models. Components of the NLRP3 inflammasome pathway such as interleukin-1β can therapeutically be targeted. Associations of genetically determined inflammasome-mediated systemic inflammation with CV

Using a spectrally resolved electron interferometry technique, we measure photoionization time delays between the 3s and 3p subshells of argon over a large 34-eV energy range covering the Cooper minima in both subshells. The observed strong variations of the 3s-3p delay difference, including a sign change, are well reproduced by theoretical calculations using the two-photon two-color random-phase

Purpose: The aim of this study is to explore teachers’ experience and understanding of classroom communication after participating in a speech-language pathologist (SLP) led in-service training on classroom communication. Method: This qualitative study used a focus group approach to explore how teachers describe their classroom communication. Twenty primary-school teachers participated. Thematic a

Objective: To determine the effectiveness of specialized rehabilitation in adults with prolonged symptoms, or risk of prolonged symptoms, following mild traumatic brain injury. Data sources: Randomized controlled trials or nonrandomized controlled studies published between 1 Jan 2000 and 10 Mar 2019 in Cochrane Controlled Register of Trials, PubMed, EMBASE, CINAHL or PsycINFO. Meta-Analyses were p

OBJECTIVES: Coronary artery calcium score (CACS) is a marker of subclinical atherosclerosis. However, there is little data related to the association between arterial stiffness and CACS in the general population. The aim of this study was to explore the association between carotid femoral-pulse wave velocity (c-f PWV), a widely accepted marker of arterial stiffness, and CACS.METHODS: Participants

INTRODUCTION: 'The diabetic hand' has traditionally referred to hand complications due to diabetes mellitus (DM), including trigger finger (TF) and Dupuytren's disease (DD). Recent publications have also proposed DM as a risk factor for carpal tunnel syndrome (CTS), ulnar nerve entrapment (UNE), and possibly osteoarthritis (OA) of the first carpometacarpal (CMC-1) joint. This study aimed to explor

Mid-infrared polarization spectroscopy was applied to detect HCl at trace level in an atmospheric pressure premixed H2/O2/Ar flame with chloroform seeding. Detection sensitivity and potential interference from water lines was investigated.

Objective:To determine viral load (VL) nonsuppression (VLN) rates, HIV drug resistance (HIVDR) prevalence, and associated factors among female sex workers (FSWs) in Ethiopia.Methods:A cross-sectional biobehavioral survey was conducted among FSWs in 11 cities in Ethiopia in 2014. Whole blood was collected, and HIVDR genotyping was performed. Logistic regression analysis was performed to identify fa

This study proposes a novel design of binders for polycrystalline cubic boron nitride (PcBN) cutting tool materials. Well-known binder phases TiC and TiN were combined with transitional metal nitrides ZrN, VN, and HfN. Performance screenings of longitudinal turning Inconel 718 and AISI 316 L highlighted the superior performance of PcBN materials with mixed TiC-ZrN and TiC-VN binders. These two sys

IntroductionThe interest in Para athletes’ health continues to increase. Still, there are few studies that have evaluated health parameters beyond injury and illness in this athlete population.ObjectiveTo assess: i) the weekly proportion of elite Para athletes reporting anxiety/depression, low sleep levels (≤7 hours) and pain over 52 weeks and; ii) and to explore whether these health parameters ar

Relative telomere length (RTL), an indicator of senescence, has been shown to be heritable but can also be affected by environmental factors, such as parental effects. Investigating heritability as well as parental effects and rearing environment can help us to understand the factors affecting offspring telomeres. Moreover, how phenotypic parental traits linked with fitness can impact offspring RT

ObjectivesThe aim of this study was to explore elite Para athletes' and coaches' perceptions of experiences of athlete health monitoring.Materials and MethodsThis study used a qualitative design, applying a phenomenographical approach. Thirteen athletes and six coaches from two different socioeconomic contexts (the Swedish and South African Paralympic programs) participated. Data were collected th

The relationships between structure and function in human knee femoral cartilage are not well-known at different stages of osteoarthritis. Thus, our aim was to characterize the depth-dependent composition and structure (proteoglycan content, collagen network organization and collagen content) of normal and osteoarthritic human femoral condyle cartilage (n = 47) and relate them to their viscoelasti

BACKGROUND: Emerging evidence suggests that animal protein foods may increase the risk of nonalcoholic fatty liver disease (NAFLD). We therefore examined the NAFLD risk reduction related to substituting plant protein foods for animal protein foods.METHODS: The cohort in North China included 14,541 participants from the Tianjin Chronic Low-Grade Systemic Inflammation and Health (TCLSIH) study, and

The Josephson junction of a strong spin-orbit material under a magnetic field is a promising Majorana fermion candidate. Supercurrent enhancement by a magnetic field has been observed in the InAs nanowire Josephson junctions and assigned to a topological transition. In this work we observe a similar phenomenon but discuss the nontopological origin by considering the trapping of quasiparticles by v
