4 ± 0.8 vs 2.3 ± 0.7, P less then .001). Clinic brachial BP, aortic BP, augmentation pressure (AP), augmentation index normalized for heart rate of 75 beats per minute (AIx@75) and cf-PWV were similar in both groups. Nutlin-3a mw In summary, there was no significant difference in central BP or arterial stiffness between patients with controlled RHTN and controlled non-RHTN. These findings suggest that the higher residual cardiovascular risk observed in patients with RHTN after achieving BP control compared to patients with more easily controlled hypertension is not likely attributable to persistent differences in central BP and arterial stiffness. © 2020 Wiley Periodicals, Inc.Colloidal crystallization is analogous to the crystallization in bulk atomic systems in various aspects, which has been explored as a model system. However, a real-time probing of the phenomenon still remains challenging. Here, a levitation system for a study of colloidal crystallization is demonstrated. Colloidal particles in a levitated droplet are gradually concentrated by isotropic evaporation of water from the surface of the droplet, resulting in crystallization. The structural change of the colloidal array during crystallization is investigated by simultaneously measuring the volume and reflectance spectra of the droplet. The crystal nucleates from the surface of the droplet at which the volume fraction exceeds the threshold and then the growth proceeds. The crystal growth behavior depends on the initial concentrations of colloidal particles and salts which determine the overall direction of crystal growth and interparticle spacing, respectively. The results show that a levitating bulk droplet has a great potential as a tool for in situ investigation of colloidal crystallization. © 2020 WILEY-VCH Verlag GmbH & Co.

This study sought to assess the contribution of ABPM to blood pressure (BP) control and antihypertensive therapy at a cardiac clinic in Ghana. Medical records of 97 patients, aged 18-85 years (mean 55), were reviewed. Among patients with clinic BP (CBP) and ambulatory BP recorded on the same day, we assessed for the different hypertension phenotypes, CBP control 6 months following ABPM, and changes to antihypertensive therapy after review of the ABPM records in patients with controlled and uncontrolled ambulatory BP. From the clinic and ambulatory BP records measured at baseline, the proportion of patients with white-coat uncontrolled hypertension (WUCH) was 19.5% (17/87) and those with masked uncontrolled hypertension (MUCH) was 16.1% (n = 14). A significant reduction in average systolic CBP in the overall cohort (-6.2 mm Hg, P less then .01) and in the uncontrolled subgroup (-8.8 mm Hg, P less then .001) at follow-up was observed. After review of the ABPM records, 51.7% of the patients on treatment had changes made in their antihypertensive therapy. Antihypertensive therapy was deintensified or left unchanged in majority of the patients with WUCH and sustained controlled hypertension. In patients with MUCH and true uncontrolled hypertension (TUCH), therapy was intensified. In conclusion, ABPM improved clinical decision-making for antihypertensive therapy and BP control. ABPM should therefore be used more often in hypertension and cardiac clinics in low/middle-income countries for optimal care. © 2020 Wiley Periodicals, Inc.Mixed-halide wide-bandgap perovskites are key components for the development of high-efficiency tandem structured devices. However, mixed-halide perovskites usually suffer from phase-impurity and high defect density issues, where the causes are still unclear. By using in situ photoluminescence (PL) spectroscopy, it is found that in methylammonium (MA+ )-based mixed-halide perovskites, MAPb(I0.6 Br0.4 )3 , the halide composition of the spin-coated perovskite films is preferentially dominated by the bromide ions (Br- ). Additional thermal energy is required to initiate the insertion of iodide ions (I- ) to achieve the stoichiometric balance. Notably, by incorporating a small amount of formamidinium ions (FA+ ) in the precursor solution, it can effectively facilitate the I- coordination in the perovskite framework during the spin-coating and improve the composition homogeneity of the initial small particles. The aggregation of these homogenous small particles is found to be essential to achieve uniform and high-crystallinity perovskite film with high Br- content. As a result, high-quality MA0.9 FA0.1 Pb(I0.6 Br0.4 )3 perovskite film with a bandgap (Eg ) of 1.81 eV is achieved, along with an encouraging power-conversion-efficiency of 17.1% and open-circuit voltage (Voc ) of 1.21 V. This work also demonstrates the in situ PL can provide a direct observation of the dynamic of ion coordination during the perovskite crystallization. © 2020 WILEY-VCH Verlag GmbH & Co.

Automated histopathology systems, preferably directly on unstained specimens, would accelerate the pathology workflow. In this study, we investigate the potential of quantitative analysis of Optical Coherence Tomography (OCT) to separate benign from malignant prostate tissue automatically. Twenty fixated prostates were cut, from which 54 slices were scanned by OCT. Quantitative OCT metrics (attenuation coefficient, residue, goodness-of-fit) were compared for different tissue types, annotated on the histology slides. To avoid misclassification, the poor-quality slides, and edges of annotations were excluded. Accurate registration of OCT data with histology was achieved in 31 slices. After removing outliers, 56% of the OCT data was compared with histopathology. The quantitative data could not separate malignant from benign tissue. Logistic regression resulted in malignant detection with a sensitivity of 0.80 and a specificity of 0.34. Quantitative OCT analysis should be improved before clinical use.
