BACKGROUND: Tumor necrosis factor (TNF) -α is of inflammatory cytokines produced chiefly by activated monocyte/macrophages, and has been implicated in the pathogenesis of Kawasaki disease (KD). We elucidated the relationship of plasma TNF-α with conventional inflammatory mediators, clinical classification, intravenous immunoglobulin (IVIG) response and coronary arteritis in the course of KD. METHODS: Seventy Chinese children with KD were enrolled and divided into 6 subgroups, including complete KD, incomplete KD, IVIG-responsive KD, IVIG-nonresponsive KD, coronary artery (CA) -noninvolvement KD and CA-involvement KD...

Acute necrotizing pancreatitis accounts for 10% of acute pancreatitis (AP) cases and is associated with a higher mortality and morbidity. Necrosis within the first 4 weeks of disease onset is defined as an acute necrotic collection (ANC), while walled off pancreatic necrosis (WOPN) develops after 4 weeks of disease onset. An infected or symptomatic WOPN requires drainage. The management of pancreatic necrosis has shifted away from open necrosectomy, as it is associated with a high morbidity, to less invasive techniques...

The neural circuitry underlying behavior in reward loss situations is poorly understood. We considered two such situations: reward devaluation (from large to small rewards) and reward omission (from large rewards to no rewards). There is evidence that the central nucleus of the amygdala (CeA) plays a role in the negative emotion accompanying reward loss. However, little is known about the function of the basolateral nucleus (BLA) in reward loss. Two hypotheses of BLA function in reward loss, negative emotion and reward comparisons, were tested in an experiment involving pretraining excitotoxic BLA lesions followed by training in four tasks: consummatory successive negative contrast (cSNC), autoshaping (AS) acquisition and extinction, anticipatory negative contrast (ANC), and open field testing (OF)...

λ-dynamics is a generalized ensemble method for alchemical free energy calcula- tions. In traditional λ-dynamics, the alchemical switch variable λ is treated as a continuous variable ranging from 0 to 1 and an empirical estimator (∆Gˆ = -β(-1)ln[P(λ > λcutoff)/P (λ < 1-λcutoff)]) is utilized to approximate the free energy (∆G = -β(-1)ln[P (λ = 1)/P(λ = 0)]) based on λ trajectories, where the cutoff value of λcutoff is empirically chosen to be near 1. In the present paper, we describe an alternative formulation of λ-dynamics that utilizes the Gibbs sampler framework which we call Gibbs Sampler λ-dynamics (GSLD)...

The basis for neuronal dysfunction following inflammatory demyelination of the central nervous system (CNS) remains poorly understood. We characterized the network response to white matter injury in the anterior visual pathway using an experimental model of optic neuritis (ON), as ON is often an early manifestation of immune-mediated CNS demyelination in multiple sclerosis (MS). Optical intrinsic signal imaging was performed before and after the induction of ON in mice to measure changes in cortical network functional connectivity...

Although neutrophils are a histologic hallmark of psoriasis, it is unclear whether neutrophils are simply effector cells or drive pathogenesis. A recent psoriasis study with murine models evaluated various chemokines, lipids, and cytokines proposing that neutrophils are key players in positive feedback loops perpetuating the disease.(1) Additionally, when neutrophils are depleted in pustular psoriasis, the disease drastically improves.(2) There is mounting evidence supporting the use of neutrophil to lymphocyte ratio (NLR) as a marker of inflammation in active psoriasis...

Episodic acidification during snowmelt is a natural phenomenon that can be intensified by acidic deposition from heavy industry. In Canada's oil sands region, acid deposition is estimated to be as much as 5% of the Canadian total and large tracks of northeastern Alberta are considered acid-sensitive because of extensive peatland habitats with poorly weathered soils. To identify the frequency, duration and severity of acidification episodes during snowmelt (the predominant hydrological period for delivery of priority pollutants from atmospheric oil sands emissions to surface waters), a 25-year record (1989 to 2014) of automated water quality data (pH, temperature, conductivity) was assembled for 3 rivers along with a shorter record (2012-2014) for another 2 rivers...

Restriction on the low conductivity of sulfur and soluble polysulfides during discharge, lithium sulfur battery is unable for further large scale applications. The current carbon based cathodes suffer from poor cycle stability and high cost. Recently, heteroatom doped carbons have been considered as a settlement to enhance the performance of lithium sulfur batteries. With this strategy, we report the low cost activated nori based N, O-doped 3D hierarchical carbon material (ANC) as a sulfur host. The N, O dual-doped ANC reveals an elevated electrochemical performance, which exhibits not only a good rate performance over 5 C, but also a high sulfur content of 81...

Stacy S Tse, Troy Kish
Drug-induced neutropenia and agranulocytosis are rare adverse events but can be fatal. Neutropenia can be induced by a myriad of drugs from almost every pharmacologic class. Octreotide is a somatostatin analogue that has been used to treat variceal bleeding, acromegaly, and severe diarrhea associated with metastatic tumors, and to reduce symptoms in the setting of malignant bowel obstruction and pseudo-obstruction. The most common adverse effects associated with octreotide include pain at the injection site and gastrointestinal effects such as loose stools, cramping, and nausea; neutropenia is not currently listed as an adverse effect of the drug...

BACKGROUND: Neutrophils serve as critical players in the pathogenesis of liver diseases. Chemokine receptors CXCR1 and CXCR2 are required for neutrophil chemotaxis to the site of inflammation/injury and are crucial in hepatic inflammatory response. However, key mechanism of neutrophil-mediated liver injury in acute-on-chronic liver failure (ACLF) remains highly elusive; which could be targeted for the development of new therapeutic interventions. METHODS: To demonstrate the role of CXCR1/CXCR2-expressing neutrophils in hepatic injury, we investigated CXCR1/CXCR2 receptor expression in 17 hepatitis B virus-related ACLF patients in comparison to 42 chronic hepatitis B and 18 healthy controls...
