BACKGROUND: Health-related quality of life (HRQoL) is an important outcome in coronary heart disease (CHD). However, variability in HRQoL indicators suggests a need to consider domain coverage. This review applies a globally accepted framework, the International Classification of Functioning, Disability and Health (ICF), to map HRQoL measures that are reliable and valid among people with CHD. METHODS: The Embase, Pubmed and PsycInfo databases were searched, with 10 observational studies comparing HRQOL among 4786 adults with CHD to 50949 controls identified...

High levels of pain, significant anxiety, and/or depressive symptoms prior to surgery put patients at elevated risk forchronic pain and prolonged opioid use following surgery. The purpose of this preliminary study was to assess the efficacy of a one-day Acceptance and Commitment Therapy (ACT) workshop in "at-risk" Veterans for the prevention of chronic pain and opioid use following orthopedic surgery. In a randomized controlled trial, 88 at-risk Veterans undergoing orthopedic surgery were assigned to Treatment as Usual (TAU; N =44) or TAU plus a 1-day ACT workshop (N = 44)...

Recent studies indicate that communication between the bovine embryo and the mother begins in the oviduct. Here, we aimed to investigate the effect of embryos on bovine oviducts for their immune responses using an in vitro model. First, zygotes were cultured with or without bovine oviduct epithelial cells (BOECs) for 4 days, when embryos had reached the 16-cell stage. At that time, we detected interferon-tau (IFNT) in embryos co-cultured with BOECs, but not in embryos cultured alone. Next, peripheral blood mononuclear cells (PBMCs) were incubated either in media from embryo alone cultures or from co-cultures of embryos with BOECs...

Alzheimer's disease (AD) is a neurodegenerative condition characterized by progressive cognitive decline and memory loss, and is the most common form of dementia. Amyloid plaques with neurofibrillary tangles are a neuropathological hallmark of AD that produces synaptic dysfunction and culminates later in neuronal loss. Amyloid PET is a useful, available and non-invasive technique that provides in vivo information about the cortical amyloid burden. In the latest revised criteria for the diagnosis of AD biomarkers were defined and integrated: pathological and diagnostic biomarkers (increased retention on fibrillar amyloid PET or decreased Aβ1-42 and increased T-Tau or P-Tau in CSF) and neurodegeneration or topographical biomarkers (temporoparietal hypometabolism on 18 F-FDG PET and temporal atrophy on MRI)...

Bleeding and thrombosis represent common complications in myeloproliferative neoplasms (MPN) and significantly contribute to morbidity and mortality. Molecular markers, including CALR mutations, were considered not only as diagnostic markers, but also as risk factors for bleeding and thrombosis associated with MPN, especially for patients in remote primary hospitals. We sought to develop an easy-to-use assay for the rapid detection of CALR type 1 (CALR-1) and type 2 (CALR-2) mutations in Philadelphia chromosome-negative MPN patients...

BACKGROUND: Systemic inflammation induces neuroinflammation and cellular changes such as tau phosphorylation to impair cognitive function, including learning and memory. This study uses a single model, laparotomy without any pathogen, to characterize these changes and their responses to anti-inflammatory treatment in the intermediate term. METHODS: In a two-part experiment, wild-type C57BL/6N mice (male, 3 month old, 25 ± 2 g) were subjected to sevoflurane anesthesia alone or to a laparotomy...

BACKGROUND: Prior studies in C. elegans demonstrated that the expression of aggregation-prone polyglutamine proteins in muscle wall cells compromised the folding of co-expressed temperature-sensitive proteins, prompting interest in whether the accumulation of a misfolded protein in pathologic features of human neurodegenerative disease burdens cellular proteostatic machinery in a manner that impairs the folding of other cellular proteins. METHODS: Mice expressing high levels of mutant forms of tau and α-synuclein (αSyn), which develop inclusion pathologies of the mutant protein in brain and spinal cord, were crossed to mice expressing low levels of mutant superoxide dismutase 1 fused to yellow fluorescent protein (G85R-SOD1:YFP) for aging and neuropathological evaluation...

In recent years, intriguing hints for the violation of lepton flavor universality (LFU) have been accumulated in semileptonic B decays, both in the charged-current transitions b→cℓ^{-}ν[over ¯]_{ℓ} (i.e., R_{D}, R_{D^{*}}, and R_{J/ψ}) and the neutral-current transitions b→sℓ^{+}ℓ^{-} (i.e., R_{K} and R_{K^{*}}). Hints for LFU violation in R_{D^{(*)}} and R_{J/ψ} point at large deviations from the standard model (SM) in processes involving tau leptons. Moreover, LHCb has reported deviations from the SM expectations in b→sμ^{+}μ^{-} processes as well as in the ratios R_{K} and R_{K^{*}}, which together point at new physics (NP) affecting muons with a high significance...

The tau fibrillar structures from the brain of an Alzheimer's patient have a core with a C-shaped motif of the third and fourth repeat domains (R3-R4). Our simulations indicated that the C-shaped motif is only stable for R3-R4, while R1-R2 tends to be linear in shape. These two structural motifs appear in the most stable K18 protofilament. Heparin can further stabilize the C-shaped R3-R4 motif, but not other repeats.

Ethanolamine plasmalogen (pPE), a major phospholipid in neuronal membranes, is specifically reduced in postmortem brains from patients with Alzheimer's disease (AD). The purpose of the present study was to compare the effects of EPA-enriched ethanolamine plasmalogen (EPA-pPE) and EPA-enriched phosphatidylethanolamine (EPA-PE) on cognitive deficiency and illustrate the possible underlying mechanisms. SD rats were divided into four groups including the sham group injected with 0.9% saline and three amyloid-β (Aβ) infusion groups, Aβ42 group, EPA-pPE group and EPA-PE group...

Fused in sarcoma (FUS) is an RNA binding protein that regulates RNA metabolism including alternative splicing, transcription, and RNA transportation. FUS is genetically and pathologically involved in frontotemporal lobar degeneration (FTLD)/amyotrophic lateral sclerosis (ALS). Multiple lines of evidence across diverse models suggest that functional loss of FUS can lead to neuronal dysfunction and/or neuronal cell death. Loss of FUS in the nucleus can impair alternative splicing and/or transcription, whereas dysfunction of FUS in the cytoplasm, especially in the dendritic spines of neurons, can cause mRNA destabilization...

This study was conducted to assess the antioxidant capacity and protective effect of the ethyl acetate fraction from persimmon ( Diospyros kaki ) (EFDK) on H₂O₂-induced hippocampal HT22 cells and trimethyltin chloride (TMT)-induced Institute of Cancer Research (ICR) mice. EFDK had high antioxidant activities and neuroprotective effects in HT22 cells. EFDK ameliorated behavioral and memory deficits in Y-maze, passive avoidance and Morris water maze tests. Also, EFDK restored the antioxidant system by regulating malondialdehyde (MDA), superoxide dismutase (SOD) and reduced gluthathione (GSH), and the cholinergic system by controlling the acetylcholine (ACh) level and acetylcholinesterase (AChE) activity and expression...

Neurofibrillary tangles composed of hyperphosphorylated tau protein are primarily neuropathological features of a number of neurodegenerative diseases collectively termed tauopathy. To understand the mechanisms underlying the cause of tauopathy, precise cellular and animal models are required. Recent data suggest that the transient introduction of exogenous tau can accelerate the development of tauopathy in the brains of non-transgenic and transgenic mice expressing wild-type human tau. However, the transmission mechanism leading to tauopathy is not fully understood...

INTRODUCTION: Home sleep apnea testing (HSAT) is a diagnostic measure for obstructive sleep apnea hypopnea syndrome (OSAHS) in moderate/high risk patients. Some HSAT companies contain automatic analysis (AA). However, guidelines recommend manual analysis (MA) despite the weak evidence for this recommendation. OBJECTIVE: Evaluate the concordance between AA and MA of HSAT to make either a diagnosis and severity classification. METHODS: We evaluated AA and MA of HSAT between 2015 and 2016...

The classic methodology of inferring a phylogenetic tree from sequence data is composed of two steps. First, a multiple sequence alignment (MSA) is computed. Then, a tree is reconstructed assuming the MSA is correct. Yet, inferred MSAs were shown to be inaccurate and alignment errors reduce tree inference accuracy. It was previously proposed that filtering unreliable alignment regions can increase the accuracy of tree inference. However, it was also demonstrated that the benefit of this filtering is often obscured by the resulting loss of phylogenetic signal...

Objective: Improving medication adherence among children with B-cell precursor acute lymphoblastic leukemia (B-ALL) has the potential to reduce relapse rates but requires an investment in resources. An economic evaluation is needed to understand the potential costs and benefits of delivering adherence-promotion interventions (APIs) as part of standard clinical care. Methods: A Markov decision analytic model was used to simulate the potential incremental cost-effectiveness per quality-adjusted life year (QALY) to be gained from an API for children with B-ALL in first continuous remission compared with treatment as usual (TAU, no intervention)...
