Background Endovascular treatment (EVT) of brain arteriovenous malformations has evolved from cyanoacrylate derivatives such as N-butyl cyanoacrylate, an adhesive glue, to ethylene vinyl copolymer-based liquid embolics such as Onyx® and SQUID® dissolved in dimethyl sulfoxide. Although these agents offer several advantages, their rapidly decreasing radiopacity, as a result of the sedimentation of tantalum powder, compromises visual control during EVT. This study aims to quantify and compare tantalum sedimentation rates of several liquid embolic agents, and determine their effects on radiopacity...

We investigated the means and timing by which mutations become fixed in the human colonic epithelium by visualizing somatic clones and mathematical inference. Fixation requires two sequential steps. First, one of approximately seven active stem cells residing within each colonic crypt has to be mutated. Second, the mutated stem cell has to replace neighbors to populate the entire crypt in a process that takes several years. Subsequent clonal expansion due to crypt fission is infrequent for neutral mutations (around 0...

The United States has national plans for the elimination of hepatitis C virus but much of US health care is organized on the state level and requires local solutions. This article describes the plans developed by New York, Massachusetts, and the city/county of San Francisco for hepatitis C virus elimination. Coalitions capitalize on existing resources and advocate for new resources to address barriers in hepatitis C virus care. Although each coalition has distinct plans, all share a commitment to groups that are disproportionately affected and are at risk for being excluded from advances in hepatitis C virus treatment and cure...

Immunotherapy has revolutionized outcomes for cancer patients, but the mechanisms of resistance remain poorly defined. We used a series of whole-genome clustered regularly interspaced short palindromic repeat (CRISPR)-based screens performed in vitro and in vivo to identify mechanisms of tumor immune evasion from cytotoxic lymphocytes [CD8+ T cells and natural killer (NK) cells]. Deletion of key genes within the tumor necrosis factor (TNF) signaling, interferon-γ (IFN-γ) signaling, and antigen presentation pathways provided protection of tumor cells from CD8+ T cell-mediated killing and blunted antitumor immune responses in vivo...

OBJECTIVES: Giant cell arteritis (GCA) is the most common form of systemic vasculitis. Glucocorticoids are an effective treatment but have significant adverse events and relapses are common. Interleukins 12 (IL-12) and 23 (IL-23) stimulate TH 1 and TH 17 responses and are implicated in the pathogenesis of GCA. The aim of this study was to evaluate the efficacy and safety of IL-12/23 blockade with ustekinumab in GCA. METHODS: We performed a prospective open label study of ustekinumab in patients with refractory GCA...

Carbon dioxide (CO2 ) electroreduction could provide a useful source of ethylene, but low conversion efficiency, low production rates, and low catalyst stability limit current systems. Here we report that a copper electrocatalyst at an abrupt reaction interface in an alkaline electrolyte reduces CO2 to ethylene with 70% faradaic efficiency at a potential of -0.55 volts versus a reversible hydrogen electrode (RHE). Hydroxide ions on or near the copper surface lower the CO2 reduction and carbon monoxide (CO)-CO coupling activation energy barriers; as a result, onset of ethylene evolution at -0...

While seemingly a ubiquitous cognitive process, the precise definition and function of surprise remains elusive. Surprise is often conceptualized as being related to improbability or to contrasts with higher probability expectations. In contrast to this probabilistic view, we argue that surprising observations are those that undermine an existing model, implying an alternative causal origin. Surprises are not merely improbable events; instead, they indicate a breakdown in the model being used to quantify probability...

Recovery-oriented principles underpin modern-day mental health care and are enhanced by consumer participation in decision-making. Understanding how consumer participation can be maximized is central to promoting recovery-oriented care. This study explored the key strategies used by mental health registered nurses and perceived by nurses to be used by peer support workers in facilitating consumer decision-making to determine similarities, differences, and possible tensions. A qualitative descriptive approach using semi-structured interviews was conducted with nine nurses employed in mental health care...

The purpose of the study was to examine the effects of altering from habitual mixed Western-based (HD) to a very low-carbohydrate high-fat (VLCHF) diet over a 4-week timecourse on performance and physiological responses during high-intensity interval training (HIIT). Eighteen moderately trained males (age 23.8 ± 2.1 years) consuming their HD (48 ± 13% carbohydrate, 17 ± 3% protein, 35 ± 9% fat) were assigned to 2 groups. One group was asked to remain on their HD, while the other was asked to switch to a non-standardized VLCHF diet (8 ± 3% carbohydrate, 29 ± 15% protein, 63 ± 13% fat) for 4 weeks...

The cholinergic system arising from the basal forebrain plays an important role in cognitive performance in Parkinson's disease (PD). Here, we analyzed cholinergic status-dependent cortical and subcortical resting-state functional connectivity in PD. A total of 61 drug-naïve PD patients were divided into tertiles based on normalized substantia innominata (SI) volumes. We compared the resting-state network from seed region of interest in the caudate, posterior cingulate cortex (PCC), and SI between the lowest (PD-L) and highest tertile (PD-H) groups...

We describe two contrasting methods of comparative environmental risk assessment for genetically modified (GM) crops. Both are science-based, in the sense that they use science to help make decisions, but they differ in the relationship between science and policy. Policy-led comparative risk assessment begins by defining what would be regarded as unacceptable changes when the use a particular GM crop replaces an accepted use of another crop. Hypotheses that these changes will not occur are tested using existing or new data, and corroboration or falsification of the hypotheses is used to inform decision-making...

BACKGROUND: Thymic stromal lymphopoietin (TSLP) is a regulator of mast cell-mediated allergic inflammatory reactions, but the manner in which TSLP contributes to allergic rhinitis (AR) remains unclear. OBJECTIVE: Here we sought to determine that TSLP plays a crucial role in AR by interacting with Src-type tyrosine kinase p56lck and STAT6 and promoting mast cells degranulation. METHODS: The effects of TSLP on mast cell degranulation and AR were analyzed in human mast cell line (HMC-1 cells), ovalbumin (OVA)-induced AR animal model, and human subjects...

The overall goal is to study the effect of low-level laser therapy (LLLT) on membrane distribution of major water channel protein aquaporin 5 (AQP5) in salivary gland during hyperglycemia. Par C10 cells treated with high glucose (50 mM) showed a reduced membrane distribution of AQP5. The functional expression of AQP5 was down regulated due to intracellular Ca2+ overload and ER stress. This reduction in AQP5 expression impairs water permeability and therefore results in hypo-salivation. A reduced salivary flow was also observed in streptozotocin (STZ)-induced diabetic mice model and the expression of AQP5 and phospho-AQP5 was down regulated...

Aims: The gut microbiome influences metabolic syndrome (MetS) and inflammation and is therapeutically modifiable. Arterial stiffness is poorly correlated with most traditional risk factors. Our aim was to examine whether gut microbial composition is associated with arterial stiffness. Methods and results: We assessed the correlation between carotid-femoral pulse wave velocity (PWV), a measure of arterial stiffness, and gut microbiome composition in 617 middle-aged women from the TwinsUK cohort with concurrent serum metabolomics data...

OBJECTIVES: The IFN-γ-release assay (IGRA) cannot differentiate active tuberculosis (TB) from latent TB infection (LTBI). We hypothesized that the TNF-α-release assay (TARA) combined with IGRA might discriminate active TB from not active TB without LTBI. METHODS: Adult patients with suspected TB, and with unrelated diseases such as herpes zoster as controls, were enrolled in an intermediate TB-burden country. Patients with confirmed or probable TB were regarded as active TB, and patients with not active TB were further classified as those having not active TB with and without LTBI based on IGRA results...

BACKGROUND: Patients in the intensive care unit (ICU) experience sleep deprivation caused by environmental disruption, such as high noise levels and 24-hour lighting, as well as increased patient care activities and invasive monitoring as part of their care. Sleep deprivation affects physical and psychological health, and patients perceive the quality of their sleep to be poor whilst in the ICU. Artificial lighting during night-time hours in the ICU may contribute to reduced production of melatonin in critically ill patients...
