This review article summarizes the relevant English literature on gout from 2010 through April 2017. It emphasizes that the current epidemiology of gout indicates a rising prevalence worldwide, not only in Western countries but also in Southeast Asia, in close relationship with the obesity and metabolic syndrome epidemics. New pathogenic mechanisms of chronic hyperuricaemia focus on the gut (microbiota, ABCG2 expression) after the kidney. Cardiovascular and renal comorbidities are the key points to consider in terms of management...

Defect-rich, boron (B) and nitrogen (N) dual-doped and inert BN covalent bonds-free graphenes (BNGs) can be successfully synthesized via a method of two-step doping combined with chemical etching. B and N doping degree and surface areas of BNGs can be enhanced facilely by chemical etching without forming inert covalent BN bonds. The as-obtained porous BNGs deliver more superior electro-catalytic activity for oxygen reduction reaction than the unetched BNGs and commercial Pt/C catalysts.

The Berry connection describes transformations induced by adiabatically varying Hamiltonians. We study how zero modes of the modular Hamiltonian are affected by varying the region that supplies the modular Hamiltonian. In the vacuum of a 2D conformal field theory, global conformal symmetry singles out a unique modular Berry connection, which we compute directly and in the dual three-dimensional anti-de Sitter (AdS_{3}) picture. In certain cases, Wilson loops of the modular Berry connection compute lengths of curves in AdS_{3}, reproducing the differential entropy formula...

Arterial stiffness and wave reflection are important components of the ventricular afterload. Therefore, we aimed to assess the arterial wave characteristics and mechanical properties of the proximal pulmonary arteries (PAs) in the hypoxic pulmonary hypertensive rat model. After 21 days in normoxic or hypoxic chambers (24 animals in each group), the animals underwent transthoracic echocardiography and pulmonary artery catheterization with a dual-tipped pressure and Doppler flow sensor wire. Wave intensity analysis (WIA) was performed...

In this study, intense single-band red-emitting upconversion nanophosphors (UCNPs) excited with 800 nm near infrared (NIR) light are reported. When a NaYF4 :Nd,Yb active-shell is formed on the 12.7 nm-sized NaGdF4 :Yb,Ho,Ce UCNP core, the core/shell (C/S) UCNPs show tunable emission from green to red depending on the Ce3+ concentration under excitation with 800 nm NIR light. Thirty mol% Ce3+ -doped C/S UCNPs exhibit single-band red emission peaking at 644 nm via a5 F5 →5 I8 transition of Ho3+ . A high Nd3+ concentration in the shell results in strong absorption at around 800 nm NIR light even though the shell thickness is not large, and small-sized C/S UCNPs (16...

A conserved blue light sensing and transduction pathway contributes to blue light-induced anthocyanin accumulation in the peel of red pear. Peel color is an economically important characteristic that influences the appearance quality of red pear, whose red color is due to anthocyanin accumulation. The process of coloration in the fruit peel is strongly influenced by light. However, how light quality influences color development remains unclear. In this study, we analyzed the effects of different light qualities on color development in the red pear 'Red Zaosu', a mutant of the hybrid cultivar 'Zaosu' of Pyrus pyrifolia and P...

Background: Assessments of energy intake (EI) are frequently affected by measurement error. Recently, a simple equation was developed and validated to estimate EI on the basis of the energy balance equation [EI = changed body energy stores + energy expenditure (EE)]. Objective: The purpose of this study was to compare multiple estimates of EI, including 2 calculated from the energy balance equation by using doubly labeled water (DLW) or activity monitors, in free-living adults...

Intestinal dwelling parasites have evolved closely with the complex intestinal microbiota of their host, but the significance of the host microbiota for metazoan pathogens and the role of their own intestinal microbiota are still not fully known. We have found that the parasitic nematode Trichuris muris acquired a distinct intestinal microbiota from its host, which was required for nematode fitness. Infection of germ-free mice and mice monocolonized with Bacteroides thetaiotaomicron demonstrated that successful T...
