Borophene sheets have been synthesized in recent experiments, but the metallic nature and structural instability of the sheets seriously prevent the outstanding emerging applications. Hydrogenated borophene has been predicted as an ideal material for nanoelectronic applications due to its high stability and excellent electronic and mechanical properties. However, the fabrication of hydrogenated borophene has still a great challenge. Here, we demonstrate that hydrogenated borophenes in large quantities can be prepared without any metal substrates by a stepwise in-situ thermal decomposition of sodium borohydride under hydrogen as the carrier gas. The borophenes with good crystallinity exhibit superior stability in strong acid or base solvents. The structure of the grown borophene is in good agreement with the predicted semiconducting alpha-boron sheet. The fabricated borophene-based memory device shows a high ON/OFF current ratio of 3 × 10 3 and a low operating voltage of less than 0.35 V as well as good stability. © 2020 WILEY-VCH Verlag GmbH & Co.

However, the current status of utilizing this test in these countries is not widely known due to lack of extensive data. We aimed to clarify the current nationwide and regional status of utilization of the urine dipstick test in an outpatient care setting and to determine the regional factors associated with adoption of this method. METHODS This cross-sectional study used openly accessible data from the national claim database that included the health insurance claims data of the Japanese population in 2017. RESULTS In total, 67 125 386 urine dipstick tests were performed compared with 1 862 700 quantitative urine protein tests and 17 544 949 urine sediment microscopy tests. Dipstick tests were employed principally for those who are >65 years old (60.3%) and, although the male population (52.5%) is generally larger, the female population is larger in age of 15-39 years and > 85 years. Multivariate analysis with several regional parameters revealed that the test was performed more commonly in the areas that accommodate greater elderly population (P  less then  0.01). CONCLUSION Despite a heated dispute, the urine dipstick test is performed even more frequently than the quantitative biochemical or microscopic sediment tests, especially in regions holding the larger elderly population, which suggests that the test forms a part of geriatric medical care.

This study evaluated the frequency and function of Tregs in patients with chronic HBV/HCV coinfection. Seventy-four untreated HBV/HCV co-infected patients were enrolled in this study. These subjects were divided into four subgroups HBV-active/HCV-active (BACA), HBV-inactive/HCV-active (BICA), HBV-active/HCV-inactive (BACI) and HBV-inactive/HCV-inactive (BICI). Treg frequency was calculated as the fraction of CD4+ Foxp3+ T cells among CD4+ T cells. Treg-mediated inhibition was measured as percent of inhibition of T-cell proliferation. The expression of interferon (IFN)-γ, tumour necrosis factor (TNF)-α and interleukin (IL)-10 with/without Treg inhibition was also studied. Among the patients, there were 8 cases of BACA (10.8%), 38 of BICA (51.4%), 14 of BACI (18.9%) and 14 of BICI (18.9%). The frequency of CD4+ Foxp3+ T cells was comparable between the four groups. The inhibitory function of Tregs among the patients in the BACA and BICA was higher than that in the BICI (BACA vs BICI, P = .0210; BICA vs BICI, P = .0301). Patients in the BACA and BICA had higher fibrosis-4 (FIB-4) scores and serum ALT levels and lower serum albumin levels than those of the other groups. ALT abnormality was significantly and independently associated with a higher Treg immunosuppressive ability. The IFN-γ expression of the effector T cells in the BACA was higher than that of the other groups. In conclusion, the inhibitory function of Tregs is higher among the HBV/HCV co-infected patients with active HCV infection. ALT abnormality plays a dominant role in Treg function. © 2020 John Wiley & Sons Ltd.OBJECTIVE A significant proportion of individuals with anorexia nervosa (AN) show high levels of autism spectrum disorder (ASD) traits, a factor associated with poorer treatment outcomes. An important question for both researchers and clinicians relates to how ASD traits should be assessed in individuals with AN. This study aimed to examine scores on the Social Responsiveness Scale adult self-report version (SRS-2) in individuals in the acute (AN) and recovered stages (REC) of illness compared to healthy controls (HCs). We also aimed to examine associations between the SRS-2 and an observational diagnostic measure, the Autism Diagnostic Observation Schedule - second edition (ADOS-2). METHOD The SRS-2 and ADOS-2 were administered to 142 adults with AN, REC, and HCs. Eating disorder (ED) psychopathology and functional impairment were also assessed. RESULTS AN and REC scored significantly higher than HCs on the SRS-2. SRS-2 scores significantly predicted ADOS-2 classification and were positively associated with ED psychopathology and functional impairment. selleck products SRS-2 scores were not associated with BMI or illness duration. CONCLUSIONS The SRS-2 may be a useful tool in screening for ASD traits in individuals with AN. Although cross-sectional, the results also suggest ASD symptoms are independent of BMI and persist in individuals recovered from AN. © 2020 The Authors.

It is often referred to as a new (or novel) psychoactive substance, a 'designer' benzodiazepine or a 'street benzodiazepine'. Increasing reports of non-medical use, identification of etizolam as an ingredient in counterfeit medications and the common identification of etizolam in drug-related deaths, highlight the need for a greater understanding of etizolam. APPROACH A rapid narrative review was conducted using PubMed and Google Scholar to synthesise what is known about etizolam to answer two research questions (i) Does the pharmacological or toxicological profile of etizolam differ from other benzodiazepines?; and (ii) What is the nature and context of non-medical use and harms related to etizolam? KEY FINDINGS Etizolam has a higher potency as an anxiolytic but lower lethality compared with diazepam. Few harms are documented with the therapeutic use of pharmaceutical products. Harms appear to be predominantly related to the use of etizolam in illicitly manufactured pills and occur almost exclusively in the context of mixed-drug toxicity.
