The electroreduction of CO2 to fuels and chemicals is an attractive strategy for valorizing CO2 emissions. In this study, we show that a Cu2O electrocatalyst prepared by a simple and potentially scalable solvothermal route effectively targeted CO evolution at low to moderate overpotentials (CECO ca. 60% after 12 h at -0.6 V vs. RHE), and that the introduction of p-block elements (In, Sn, Ga, Al) into the catalyst can be employed to tune its selectivity. SEM, HRTEM, and voltammetric analyses revealed that the Cu2O catalyst undergoes extensive surface restructuring (favorable for CO evolution) under reaction conditions...

RNA-induced gene silencing has been widely applied as a powerful research tool in drug development due to its sequence-specific degradation of target mRNA. Conditional regulation of gene functions with small interfering RNAs (siRNAs) is highly useful, especially when specific gene expression regulation with spatiotemporal resolution and amplitude is desired. Here, the synthesis of a series of new caged siRNAs with vitamin E (vitE) modification and/or a single photolabile linker at the 5' terminal is described...

BACKGROUND: Dementia is a chronic, progressive and ultimately fatal neurodegenerative disease. Advanced dementia is characterised by profound cognitive impairment, inability to communicate verbally and complete functional dependence. Usual care of people with advanced dementia is not underpinned universally by a palliative approach. Palliative care has focused traditionally on care of people with cancer but for more than a decade, there have been increased calls worldwide to extend palliative care services to include all people with life-limiting illnesses in need of specialist care, including people with dementia...

BACKGROUND: Inspection systems are used in healthcare to promote quality improvements (i.e. to achieve changes in organisational structures or processes, healthcare provider behaviour and patient outcomes). These systems are based on the assumption that externally promoted adherence to evidence-based standards (through inspection/assessment) will result in higher quality of healthcare. However, the benefits of external inspection in terms of organisational-, provider- and patient-level outcomes are not clear...

In this study, effects of grazing-experienced heifer presence on foraging behavior development at the feeding station (FS) scale for first-grazing season calves were determined. A group of four calves grazing alone (C), and another comprising four calves (Wc) and three grazing-experienced heifers (Wh), were alternately stocked every day for 2 h on the same pasture for 26 days. The foraging time budget for Wc was significantly longer than that for C (P < 0.05) on day 7, and was similar to that for Wh on all days...

Animal by-products can be recycled and used as sources of essential nutrients. Water-soluble heme iron (WSHI), a functional food additive for supplementing iron, is produced by processing animal blood. In this study, we investigated the effects of dietary supplementation of 3% WSHI and exercise training for 4 weeks on the accumulation of abdominal fat and lipid metabolism in mice fed high-fat diet. Exercise-trained mice had significantly less perirenal adipose tissue, whereas WSHI-fed mice tended to have less epididymal adipose tissue...

BACKGROUND: Infantile hemangiomas (IH) are common benign tumors in infancy. Most IH resolve spontaneously, but some require treatment due to ulceration, functional impairment or cosmetic disfiguration. While systemic propranolol is effective in many cases, laser therapy may be a safe topical alternative. OBJECTIVE: To assess the efficacy of combined Nd:YAG/pulsed dye laser (PDL) or PDL alone for therapy of IH. PATIENTS AND METHODS: 271 IH in 149 infants were treated with combined Nd:YAG/PDL or PDL alone...

The efficacy of treatment for intravenous elemental mercury intoxication has not been fully studied with regard to clinical outcomes, and treatment recommendations vary. We treated a 41-year-old man with a history of drug abuse and depression who attempted suicide using 1 mL (13.53 g) metallic Hg i.v. He was admitted to the hospital two months later for dyspnoea and thoracic pain and was diagnosed with pneumonia. Hg deposits were seen in the lungs and extra-pulmonary organs. His blood level (372 μg/L) exceeded the population level of 5 μg/L by more than 70-fold...

Upconverting nanoparticles show potential applications in the field of photovoltaics and array-based detection devices. While fluorescence enhancement using interference of incident radiation is well known in Stokes-shift type systems such as fluorescent dyes; the effect of such interference geometry in nonlinear Anti-Stokes type emission, such as in upconversion rare earth photophysics is demonstrated for the first time. This work describes in detail the influence of the interference modulation on both the excitation (interion energy transfer) and radiative decay with nonradiative decay processes active between emissive levels...

R Flatabø, A Coste, M M Greve
Scanning electron microscopy is perhaps the most important method for investigating and characterizing nanostructures. A well-known challenge in scanning electron microscopy is the investigation of insulating materials. As insulating materials do not provide a path to ground they accumulate charge, evident as image drift and image distortions. In previous work, we have seen that sample charging in arrays of metal nanoparticles on glass substrates leads to a shrinkage effect, resulting in a measurement error in the nanoparticle dimension of up to 15% at 10 kV and a probe current of 80 ± 10 pA...

Photoacoustic tomography has emerged as a promising non-invasive imaging technique that integrates the merits of high optical contrast with high ultrasound resolution in deep scattering medium. Unfortunately, the blood background in vivo seriously impedes the quality of imaging due to its comparable optical absorption with contrast agents, especially in conventional linear photoacoustic imaging modality. In this study, we demonstrated that two hybrids consisting of gold nanorods (Au NRs) and zinc tetra(4-pyridyl)porphyrin (ZnTPP) exhibited a synergetic effect in improving optical absorption, conversion efficiency from light to heat, and thermoelastic expansion, leading to a notable enhancement in both linear (four times greater) and nonlinear (more than six times) photoacoustic signals as compared with conventional Au NRs...

Specific intermolecular interactions, in particular H-bonding, have a strong influence on the structural, thermal and relaxation characteristics of polymers. We report here the results of molecular dynamics simulations of Nylon 6 which provides an excellent example for the investigation of such an influence. To demonstrate the effect of proper accounting for H-bonding on bulk polymer properties, the AMBER99sb force field is used with two different parametrization approaches leading to two different sets of partial atomic charges...

PurposeRanibizumab, an anti-vascular endothelial growth factor, and dexamethasone, a corticosteroid, have been shown to be effective in treating macular oedema secondary to retinal vein occlusion (RVO) (central RVO (CRVO) and branch RVO (BRVO)). Their real-world usage, however, has yet to be compared. We therefore evaluated ophthalmology visits for both drugs using US patient-level data.MethodsThe IMS Health Real-World Data Medical Claims database was used to identify treatment-naive patients receiving ranibizumab intravitreal injections or dexamethasone intravitreal implants between June 2010 and February 2014 who had 12 months of follow-up data...

Over the past decade, endoplasmic reticulum (ER) stress has emerged as an important mechanism involved in the pathogenesis of cardiovascular diseases including heart failure. Cardiac therapy based on ER stress modulation is viewed as a promising avenue toward effective therapies for the diseased heart. Here, we tested whether sirtuin-1 (SIRT1), a NAD(+)-dependent deacetylase, participates in modulating ER stress response in the heart. Using cardiomyocytes and adult-inducible SIRT1 knockout mice, we demonstrate that SIRT1 inhibition or deficiency increases ER stress-induced cardiac injury, whereas activation of SIRT1 by the SIRT1-activating compound STAC-3 is protective...

Acute myeloid leukemia (AML) is deadly hematologic malignancy. Despite a well-characterized genetic and molecular landscape, targeted therapies for AML have failed to significantly improve clinical outcomes. Over the past decade, proteasome inhibition has been demonstrated to be an effective therapeutic strategy in several hematologic malignancies. Proteasome inhibitors, such as bortezomib and carfilzomib, have become mainstays of treatment for multiple myeloma and mantle cell lymphoma. In light of this success, there has been a surge of literature exploring both the role of the proteasome and the effects of proteasome inhibition in AML...
