Nitric oxide synthases (NOS) are a family of isoforms responsible for the synthesis of the potent dilator nitric oxide (NO). Expression of inducible NOS (iNOS) occurs in conditions of inflammation, and produces large amounts of NO. In pathological conditions iNOS is regarded as a harmful enzyme and is proposed to be a major contributor to diseases of the cardiovascular system such as atherosclerosis. In this review, we address the notion that iNOS is a detrimental enzyme in disease and discuss its potentially beneficial roles...

Over the past decade, the use of check-all-that-apply questions has become an easier and faster alternative to traditional sensory profiles using trained assessors, allowing the characterisation of a product by consumers. In this study, 65 consumers evaluated the acceptability of six artisan Uruguayan sheep cheese samples during a six-month storage period, providing a descriptive profile using a check-all-that-apply questionnaire consisting of 32 sensory and non-sensory terms. Although the acceptability of five of the six samples was not modified during storage, the consumers were able to perceive changes in the texture and flavour of products, providing a sensory profile of the cheeses...

High-grade glioma (HGG) is a lethal cancer, which is characterized by very poor prognosis. To help optimize treatment strategy, accurate preoperative prediction of HGG patient's outcome (i.e., survival time) is of great clinical value. However, there are huge individual variability of HGG, which produces a large variation in survival time, thus making prognostic prediction more challenging. Previous brain imaging-based outcome prediction studies relied only on the imaging intensity inside or slightly around the tumor, while ignoring any information that is located far away from the lesion (i...

Immune cells infiltrating the tubulointerstitium critically contribute to the progression of chronic kidney disease. In this issue of Kidney international, Law et al. provide first evidence for a role of natural killer cells in the perpetuation of tubulointerstitial fibrosis in human renal disease. By detailed flow cytometric characterization of leukocytes isolated from kidney biopsies of chronic kidney disease patients, they define accumulation of natural killer cells as a feature of fibrotic kidney tissue and provide insight into potential mechanisms of how these cells might promote chronic kidney inflammation...

Varicella and zoster continue to cause significant morbidity and even mortality in children and adults. Complications include bacterial superinfection, central nervous system manifestations such as meningitis, encephalitis, and cerebellar ataxia, and pain syndromes especially post herpetic neuralgia. Many developed countries but not all, are now administering live attenuated varicella vaccine routinely, with a decrease in the incidence of disease, providing personal and herd immunity. There is some controversy, however, in some countries concerning whether a decrease in the circulation of wild type virus will result in loss of immunity to VZV in persons who have already had varicella...

The involvement of consumers in handover with nurses has been identified as reducing miscommunication and a reduction in adverse events in generalist nursing settings. Mental health (MH) care is complex, and handover practices need to fit with the philosophy of recovery-focussed practice. Recovery-focussed practice recognizes the person at the centre of care as an expert in their own treatment and decision-making. The aim of the present study was to explore the views of consumers with a mental illness, without prior involvement in nursing handover, about their need to be involved in nursing handover on an acute mental health inpatient unit...

OBJECTIVES: Assess implicit weight bias in children 9 to 11 years old. METHODS: Implicit weight bias was measured in children ages 9 to 11 (N = 114) by using the Affect Misattribution Procedure. Participants were shown a test image of a child for 350 milliseconds followed by a meaningless fractal (200 milliseconds), and then they were asked to rate the fractal image as "good" or "bad." We used 9 image pairs matched on age, race, sex, and activity but differing by weight of the child...

We present an automated algorithm for unified rejection and repair of bad trials in magnetoencephalography (MEG) and electroencephalography (EEG) signals. Our method capitalizes on cross-validation in conjunction with a robust evaluation metric to estimate the optimal peak-to-peak threshold - a quantity commonly used for identifying bad trials in M/EEG. This approach is then extended to a more sophisticated algorithm which estimates this threshold for each sensor yielding trial-wise bad sensors. Depending on the number of bad sensors, the trial is then repaired by interpolation or by excluding it from subsequent analysis...

The central objective was to identify the role of the PI3K-Akt activation pathway on the neuroprotection of δ-opioid receptor agonist (DADLE) against cerebral ischemia-reperfusion (I/R) injury in a rat model. Fifty-five male Sprague-Dawley (SD) rats were included to establish a middle cerebral artery occlusion (MCAO) model which were then divided into the sham, MCAO, LY294002 (MCAO+DADLE+LY294002 [inhibitor of PI3K-Akt pathway]), DADLE (MCAO+DADLE) and DMSO (MCAO+DADLE+DMSO [dimethyl sulphoxide]) groups. The cerebral infarction (CI) volume and nerve cell apoptosis was determined using TTC and TUNEL staining...

As part of a senior leadership class in an undergraduate baccalaureate nursing program in the northeastern United States, we conducted an experiential, theater-based workshop designed to increase student awareness of the micro-dynamics of power and the enactment of status in their day-to-day lives. These exercises allowed student participants to embody status and power and understand it in ways that they did not after simply completing assigned readings. At the conclusion of the workshop the participants were asked to reflect on their status habits and the consequences of these habits in a single hand-written page...

Neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR) and monocyte-lymphocyte ratio (MLR) have recently been used as indicators of inflammation. Higher MLR and PLR values have been determined in the euthymic and manic periods in patients with bipolar disorder compared to a control group. High NLR values were determined in the only study investigating this ratio in schizophrenia patients. The purpose of this study was to compare NLR, PLR and MLR values and complete blood count elements in patients receiving treatment and hospitalized due to schizophrenic psychotic episode and bipolar disorder manic episode...

A series of computational methods for pKa shift prediction are extensively tested on a set of benchmark protein systems, aiming at identifying pitfalls and evaluating their performance on high variants. Including 19 ASP residues in 10 protein systems, the benchmark set consists of both residues with highly shifted pKa values as well as those varying little from the reference value, with an experimental RMS free energy differences of 2.49 kcal/mol with respect to blocked amino acid, namely the RMS pKa shift being 1...

Statins are a group of medicines that can help to lower the level of low-density-lipoprotein(LDL) cholesterol "bad cholesterol" in the blood. Having a high level of LDL cholesterol is potentially dangerous, as it can lead to a hardening and narrowing of arteries (atherosclerosis) and cardiovascular disease (CVD), Atorvastatin is one of the oldest member of the statin family and is used in the treatment of dyslipidemia and the prevention of cardiovascular disease. Atorvastatin was first made in August 1985 and from 1996 to 2012 under the trade name Lipitor, atorvastatin became the world's best selling drug...

Many older people have a bad oral health, with (root) caries a prevalent cause. Alarming results of research projects raise the question whether sufficient preventive measures are being taken to prevent the development and progress of (root) caries in frail older people. A review of the recent literature revealed that in frail older people and physically or cognitively impaired adults, daily use of a 5,000 ppm fluoride toothpaste and quarterly application of chlorhexidine or sodium fluoride can decrease by half the risk of root caries...

Thrombocytosis has been suggested to be a poor prognostic indicator in malignancies. Studies have shown that thrombocytosis is associated with a poor prognosis in various gynecological malignancies such as carcinoma ovary, cervical cancer, and endometrial cancer. The aim of this study is to analyze the impact of thrombocytosis on the prognosis of gynecological cancer. All the relevant data were retrieved by PubMed, MEDLINE, and Web of Science, and then studies were chosen in this analysis of association between thrombocytosis and gynecological malignancy...

REVIEW
Zhe Hu, Qiannan Liu, Shu-Lei Chou, Shi-Xue Dou
Rechargeable sodium-ion batteries (SIBs), as the most promising alternative to commercial lithium-ion batteries, have received tremendous attention during the last decade. Among all the anode materials for SIBs, metal sulfides/selenides (MXs) have shown inspiring results because of their versatile material species and high theoretical capacity. They suffer from large volume expansion, however, which leads to bad cycling performance. Thus, methods such as carbon modification, nanosize design, electrolyte optimization, and cut-off voltage control are used to obtain enhanced performance...

Myotonic dystrophy, or Steinert's disease, is the most common form of muscular dystrophy that occurs in adults. This multisystemic form involves the skeletal muscles but affects also the eye, the endocrine system, the central nervous system, and the cardiac system. The weakness of the facial muscles causes a characteristic facial appearance frequently associated with malocclusions. Young people with myotonic dystrophy, who also have severe malocclusions, have bad oral functions such as chewing, breathing, and phonation...

Osteoarthritis (OA) is a common and dynamic joint disease, including the articular cartilage, underlying bones, and synovium. In particular, OA is considered as the degeneration of the cartilage. Tectorigenin (Tec) can affect many biological processes. However, its effect on articular chondrocytes remains unclear. This study aimed to assess the role of Tec in articular cartilage. In vitro, Tec inhibited the expression levels of type X collagen, cyclooxigenase-2, matrix metalloproteinase (MMP)-3, and MMP-13 gene but enhanced those of Runx1, type II collagen, and aggrecan in the presence of IL-1β...
