The photocatalytic activity of plasmonic Au/TiO2 nanoparticles (NPs) is dependent on distances between Au and TiO2. The preparation of plasmonic NPs is still a challenge because of an inherent lattice mismatch on heterogeneous interfaces. The combination between Au and TiO2 NPs often exhibits physical adsorption, which affect block the electron transferring process by photo-induction from TiO2 to Au NPs and weaken the photocatalytic activity. In this work an approach for preparing plasmonic Au/TiO2 NPs with perfect hetero-interface was proposed based on reconstruction of anatase TiO2 with (101) surface and in-situ reduction of Au NPs...

BACKGROUND: In Central America, chronic interstitial nephritis of agricultural communities (CINAC) has reached epidemic proportions. Clusters of cases have been described in several farming communities. Its aetiology remains uncertain and a controversy exists on its key triggers, among them the heat stress-dehydration mechanism and the toxic exposure to agrochemicals. METHODS: This study analysed the mortality pattern and trend of chronic kidney disease code N18 (CKD-N18) according to the International Statistical Classification of Diseases and Related Health Problems-10th Revision, the proxy and the underlying cause of death, in four selected Central American countries from 1997 to 2013...

Many Americans between 45 and 65 years of age experience hemorrhoids. Hemorrhoidal size, thrombosis, and location (i.e., proximal or distal to the dentate line) determine the extent of pain or discomfort. The history and physical examination must assess for risk factors and clinical signs indicating more concerning disease processes. Internal hemorrhoids are traditionally graded from I to IV based on the extent of prolapse. Other factors such as degree of discomfort, bleeding, comorbidities, and patient preference should help determine the order in which treatments are pursued...

Nanoscale alloying constitutes an increasingly-important pathway for design of catalysts for a wide range of technologically important reactions. A key challenge is the ability to control the surface catalytic sites in terms of the alloying composition, thermochemical treatment and phase in correlation with the catalytic properties. Herein we show novel findings of the nanoscale evolution of surface catalytic sites on thermochemically-tuned gold-palladium nanoalloys by probing CO adsorption and oxidation using in situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) technique...

Nitrogen is one of the most important nutrients for plant growth and hence heavily applied in agricultural systems via fertilization. Nitrification, that is, the conversion of ammonium via nitrite to nitrate by soil microorganisms, however, leads to nitrate leaching and gaseous nitrous oxide production and as such to an up to 50% loss of nitrogen availability for the plant. Nitrate leaching also results in eutrophication of groundwater, drinking water and recreational waters, toxic algal blooms and biodiversity loss, while nitrous oxide is a greenhouse gas with a global warming potential 300× greater than carbon dioxide...

INTRODUCTION: Despite small numbers, men in nursing faculty positions provide unique diverse perspectives that are important to the strength of the profession. Nationwide, calls for increased numbers of diverse faculty continue. Despite this, the numbers of male nurses entering academic remain low. The purpose of this study was to identify and describe experiences of male nursing faculty in an effort to better understand what attracts male nurses to a role in academia, and what advice is most important when considering entering academia...

The formulation of accurate clinical case definitions is an integral part of an effective process of public health surveillance. Although such definitions should, ideally, be based on a standardized and fixed collection of defining criteria, they often require revision to reflect new knowledge of the condition involved and improvements in diagnostic testing. Optimal case definitions also need to have a balance of sensitivity and specificity that reflects their intended use. After the 2009-2010 H1N1 influenza pandemic, the World Health Organization (WHO) initiated a technical consultation on global influenza surveillance...

We report a demonstration of vapor-phase Rubidium (Rb) density stabilization in a vapor cell using a solid-state electrochemical Rb source device. Clear Rb density stabilization is observed. Further demonstrations show that the temperature coefficient for Rb density can be reduced more than 100 times when locked and the device's power consumption is less than 10 mW. Preliminary investigation of the locking dynamic range shows that the Rb density is well stabilized when the initial density is five times higher (33 × 109 /cm3) than the set point density (6 × 109 /cm3)...

BACKGROUND/PURPOSE: Following intradermal injection, hyaluronic acid (HA)-based fillers tend to spread within the reticular dermis and to distribute between the dermal fibers. This biointegration is commonly measured qualitatively using histological methods. We developed a "toolbox" consisting of a visual scoring and a semi-automatic image analysis method using internal developed algorithm to quantitate the biointegration of Restylane® in histological sections. METHODS: Restylane® was injected intradermally in the abdominal skin of 10 healthy human subjects scheduled for abdominoplasty...

MicroRNAs (miRNAs) are considered 'micro- managers of gene expression' and awareness of their fundamental role in the control of biological functions is constantly increasing. Bone formation and homeostasis are complex processes involving the differentiation and interaction of various cell types. Several miRNAs have been shown to be involved in different pathways and stages in the regulation of normal and abnormal bone formation and turnover. This present review focuses on the involvement of miRNAs in terms of their effect on the commitment of bone marrow mesenchymal stem cells towards osteogenesis, adipogenesis and chondrogenesis, respectively...

Properties of electrons in non-crystalline (alias disordered) systems has been a very active research topic for over half a century, since Anderson's ground breaking paper on localization. In strongly disordered systems electrons become Anderson and Mott localized. Interactions become important because screening by localized electrons is ineffective. Dynamical theories for such systems have long been controversial. Nevertheless one theory came to prominence in the literature and is often invoked and/or used...

Using drift-diffusion simulations, we investigate the voltage dependence of the dark current in single carrier devices, typically used to determine charge-carrier mobilities. For both low and high voltages, the current increases linearly with the applied voltage. Whereas the linear current at low voltages is mainly due to space charge in the middle of the device, the linear current at high voltage is caused by charge-carrier saturation due to a high degree of injection. As a consequence, the current density at these voltages does not follow the classical square law derived by Mott and Gurney, and we show that for trap-free devices, only for intermediate voltages, a space-charge-limited drift current can be observed with a slope that approaches two...

We report on the observation of new properties of secondary cosmic rays Li, Be, and B measured in the rigidity (momentum per unit charge) range 1.9 GV to 3.3 TV with a total of 5.4×10^{6} nuclei collected by AMS during the first five years of operation aboard the International Space Station. The Li and B fluxes have an identical rigidity dependence above 7 GV and all three fluxes have an identical rigidity dependence above 30 GV with the Li/Be flux ratio of 2.0±0.1. The three fluxes deviate from a single power law above 200 GV in an identical way...

We analyze the propagation of correlations after a sudden interaction change in a strongly interacting quantum system in contact with an environment. In particular, we consider an interaction quench in the Bose-Hubbard model, deep within the Mott-insulating phase, under the effect of dephasing. We observe that dissipation effectively speeds up the propagation of single-particle correlations while reducing their coherence. In contrast, for two-point density correlations, the initial ballistic propagation regime gives way to diffusion at intermediate times...

Lupines (Lupinus spp.) are a common plant legume species found on western U.S. rangelands. Lupinus spp. may contain quinolizidine and or piperidine alkaloids that can be toxic and or teratogenic to grazing livestock. Alkaloid profiles may vary between and within a species. The objectives of this study were to 1) further explore the characteristic alkaloid profiles of L. sulphureus using field collections and 2) to explore the phylogenetic relationship of the different populations and chemotypes of L. sulphureus using AFLP method of DNA fingerprinting, thus providing possible explanations to the phenomena of multiple chemotypes within a species...
