Concerning La2Mo2O9, there is no effect following the insertion of Bi, implying that the role of Bi is insignificant.Abundant pyridinic nitrogen in the triazine units of covalent triazine frameworks (CTFs) is very useful in various heterogeneous catalysis reactions. PLX5622 clinical trial Herein, a tunable CTF platform with the same porous structure was designed and synthesized to study the interaction between palladium/platinum (Pd/Pt) and pyridinic nitrogen of CTFs. The smaller Pd nanoparticles were formed because of the stronger interaction between Pd and pyridinic nitrogen atoms of CTFs, which is more beneficial for the separation of photogenerated electron-hole pairs. Moreover, the stronger interaction between the Pd nanoparticles and CTFs is also beneficial for photoelectron transfer. Under the same conditions, the hydrogen evolution rate of 1 wt % Pd@CTF-HC6 is up to 11 times more than that of 1 wt % Pt@CTF-HC6. The hydrogen evolution rate of 1 wt % Pd@CTF-N approaches 10 556 μmol h-1 g-1 and is about 5 times more than that of 1 wt % Pt@CTF-N.γ-Alumina, a widely used industrial catalyst support, undergoes irreversible transformation into various aluminum hydroxides under hydrothermal (HT) conditions, resulting in strong modification of its intrinsic properties. Most of the strategies that have been proposed to prevent or at least minimize its transformation into oxy-hydroxides consist in covering the alumina surface with a hydrophobic carbon layer, making it less sensitive to modifications induced by water. However, such methods necessitate high carbon contents, which significantly modifies structural and chemical properties of alumina. Here, we propose a new method based on a series of adsorption/pyrolysis cycles using sorbitol molecules previously adsorbed on specific hydration sites of the (110) faces of γ-alumina crystals. These sites, which are responsible for the dissolution of γ-alumina crystals in water, are thus selectively protected by carbon clusters, with the rest of the surface being totally exposed and accessible to adsorbates. Under HT conditions (10 h in water at 200 °C), the formation of hydroxides is almost totally suppressed by covering less than 25% of the surface with only 7 wt % carbon, which is far below the amount necessary to achieve similar results with more conventional carbon deposition methods.Objective There are limited number of studies evaluating iron overload in childhood leukemia by magnetic resonance imaging (MRI). The aim of this study was to determine the liver iron content (LIC) by MRI in children with acute lymphoblastic leukemia (ALL), who had been completed treatment, and to compare with serum iron parameters. Materials and Methods A total of 30 patients between the ages of 7 and 18 who completed ALL treatment were included in the study. Serum iron parameters [serum iron, serum ferritin (SF), and total iron binding capacity], liver function tests were studied. R2 MRI was performed for determining LIC. Results Normal LIC were detected in 22 (63.4%) of the cases. Seven (23.3%) had mild and 1 (3.3%) had moderate liver iron deposition. In contrast, severe iron overload was not detected in any of the cases. LIC levels were correlated with the numbers of packet red blood cell (pRBC) transfusions (r = 0.637, p less then 0.001), pRBC transfusion volume (r = 0.449, p less then 0.013), SF levels (r = 0.561, p = 0.001), transferrin saturation (r=0.353 , p = 0.044). In addition, a positive correlation was found between the number of pRBC transfusions and SF levels (r = 0.595, p less then 0.001). Conclusion We showed that the frequency of liver iron deposition was low and clinically less significant after the end of the treatment in childhood ALL patients. LIC was demonstrated to be related with SF and transfusion history. These findings support that SF and transfusion history may be used as a reference for monitoring iron accumulation or identifying cases for further examination such as MRI.Despite the focus on quality in care homes, and the body of evidence that drives policy and practice, care home residents in Wales experience variations in quality of care. Quality is not easily defined, and care providers may have differing views on quality and how it is monitored. Health and social care professionals - including nurses - should understand the factors that affect quality in care homes. Quality improvement projects can support the development of a workplace culture that can sustain quality in care homes. This article defines quality, details methods that may be used to monitor quality, and outlines how quality in care homes can be improved. © 2020 RCN Publishing Company Ltd. All rights reserved.

AIM To demonstrate why constructivist grounded theory (CGT) is a suitable technique for unravelling experiences of mental-health recovery. DISCUSSION Mental-health recovery is still an emerging concept in Singapore. CGT can guide research design and analysis, enabling more culturally specific understandings to emerge. The authors explain the main features of CGT, as well as the strengths and limitations of the methodology and possible issues researchers may encounter applying it. CONCLUSION Suitable frameworks to guide research into mental-health recovery are urgently needed and CGT provides a flexible but systematic approach for multi-ethnic environments. IMPLICATIONS FOR PRACTICE CGT has the potential to guide deep exploration of and theory-development concerning mental-health recovery in Singapore and other countries with similar social and cultural settings. © 2020 RCN Publishing Company Ltd.

We evaluated the influence of BMI on lung ultrasonography (LUS) findings indicative of pulmonary congestion (i.e. B-lines) in patients with chronic and acute HF (AHF). METHODS AND RESULTS We analysed ambulatory chronic HF (n = 118) and hospitalized AHF (n = 177) patients (mean age 70 years, 64% men, mean BMI 29 kg/m2 , mean ejection fraction 42%) undergoing echocardiography and LUS in eight chest zones. B-lines and chest wall thickness (skin to pleura) on ultrasound were quantified offline and blinded to clinical findings. NT-proBNP was available in AHF patients (n = 167). In chronic HF, B-line number decreased by 18% per 5 unit increase in BMI [95% confidence interval (CI) -35% to +5%, P = 0.11]. In AHF, the number of B-lines decreased by 12% per 5 unit increase in BMI (95% CI -19% to -5%, P = 0.001), whereas NT-proBNP concentration decreased by 28% per 5 unit increase in BMI (95% CI -40% to -16%, P 6 B-lines were observed in half of AHF patients with severe obesity.
