PURPOSES: The aim of this study was to investigate the serum levels and clinical significance of interleukin 1β (IL-1β) and IL-6 in children with hyperuricemia (HUA). METHODS: We included 71 children with HUA and 71 children with no HUA as control subjects. Children with HUA were divided into groups I and II according to whether they had a history of acute gout-like attacks (including sudden monoarthritis of rapid onset with intense pain and swelling). Group I was examined twice (A, in the acute phase; B, in the remission phase)...

BACKGROUND: Lung inflammation is one of the main consequences of intestinal ischemia reperfusion (intestinal IR) and, in severe cases, can lead to acute respiratory distress syndrome and death. We have previously demonstrated that estradiol exerts a protective effect on lung edema and cytokine release caused by intestinal IR in male rats. MATERIALS AND METHODS: We investigated the role of estradiol on the generation of interleukin (IL)-1β, IL-10, vascular endothelial growth factor (VEGF), and cytokine-induced neutrophil chemoattractant 1 (CINC-1) in a female rat model of intestinal IR...

BACKGROUND: Stroke still has a high incidence with a tremendous public health burden and it is a leading cause of mortality and disability. However, biomarkers for early diagnosis are absent and the metabolic alterations associated with ischemic stroke are not clearly understood. The objectives of this case-control study are to identify serum biomarkers and explore the metabolic alterations of ischemic stroke. METHODS: Metabonomic analysis was performed using ultra-performance liquid chromatography quadrupole time-of-flight tandem mass spectrometry and multivariate statistical analysis was employed to study 60 patients with or without ischemic stroke (30 cases and 30 controls)...

INTRODUCTION: Topiroxostat, a recently developed xanthine oxidase inhibitor, is expected to have fewer adverse effects than allopurinol because it has different mechanism of action from alloprinol. However, its dosage, usage and safety have not been established in patients with impaired renal function or those undergoing dialysis at the development since no studies was conducted in these patients. METHODS: Cross over clinical trial using 3 months of allopurinol and topiroxostat on 27 maintain Japanese HD patients were carried out...

In this work, we demonstrate the ultra-sensitive and selec-tive detection of dopamine by means of a neuro-inspired device platform without the need of a specific recognition moiety. The sensor is a whole organic device featuring two electrodes made of poly(3,4-ethylenedioxythiophene):polystyrene sulfonate - PEDOT:PSS - patterned on a polydymethylsiloxane - PDMS - flexible substrate. One electrode is pulsed with a train of voltage square waves, to mimic the pre-synaptic neuron behavior, while the other is used to record the displacement current, mimicking the post-synaptic neuron...

BACKGROUND & AIMS: As dietary components are delivered directly to the periportal zone of the liver lobule, there is the potential for greater injury in this zone (zone 1) compared to the perivenous zone (zone 3). We investigated the associations between dietary fructose consumption and uric acid concentrations and differential zonal injury in periportal and perivenous zones. METHODS: 271 children's histological images were scored in five periportal and five perivenous...

Xanthine oxidase (XO) is an important enzyme responsible for conversion of purine bases to uric acid and represents the major source of reactive oxygen species (ROS) production in circulation. Since pathophysiological mechanism of the relationship between XO activity and urinary albumin excretion (UAE) rate is not well elucidated, we aimed to investigate this association in patients with diabetes mellitus type 2 (DM2). In addition, we wanted to examine whether uric acid itself plays an independent role in albuminuria onset and progression, or it is only mediated through XO activity...

BACKGROUND: The respiratory epithelium is a major site for disease interaction with inhaled allergens. Additional to IgE-dependent effects, allergens contain proteases that may stimulate human bronchial epithelial cells (HBECs) through protease-activated receptors, causing the release of mediators important in driving Th2 mediated immune responses. OBJECTIVE: We aimed to investigate if different allergens induce metabolite DAMPs such as ATP and uric acid (UA) release in HBECs...

The role of serum uric acid (SUA) as a prognostic marker for incident heart failure (HF) in hypertensive subjects is uncertain. We have prospectively examined the relationship between SUA and incident HF in 3440 men aged 60-79years separately in those on and not on antihypertensive treatment who were followed up for a mean period of 15years. Men on SUA lowering drugs and those with history of HF or myocardial infarction were excluded. There were 260 incident HF cases. The men were divided into three groups of SUA concentrations/levels (<350, 350-410 and >410μmol/L)...
