Atomic layer deposition (ALD) has attracted much attention, particularly for applications in nanoelectronics because of its atomic-level controllability and high-quality products. In this study, we developed a plasma-enhanced atomic layer deposition (PEALD) process to fabricate a homogeneous indium aluminum oxide (IAO) semiconductor film. Trimethylaluminum (TMA) and dimethylaluminum isopropoxide (DMAI) were used as Al precursors, which yielded different compositions. Density functional theory (DFT) calculations on the surface reactions between indium and aluminum precursors showed that while highly reactive TMA would etch In, DMAI with lower reactivity would allow indium to persist in the films, resulting in a more controlled doping of Al. The In/Al composition ratio could be further precisely controlled by adjusting the indium precursor dose time to sub-saturation. IAO based on DMAI was applied to fabricate thin-film transistors (TFTs), showing that Al can be a carrier suppressor of indium oxide. TFTs with PEALD IAO containing 3.8 atomic % Al showed a turn-on voltage of -0.4 ± 0.3 V, a subthreshold slope of 0.09 V/decade, and a field effect mobility of 18.9 cm2/(V s).Three independent Ti-oxo clusters (TOCs) that contain 6, 8, and 12 Ti atoms in the cores and alkyl groups on the surface were developed as cathode interlayers in bulk-heterojunction organic solar cells (OSCs). These TOCs have precise chemical structures with a single crystal, excellent solubility in methanol, and well-aligned work function. Smooth films can be facilely obtained by spin-casting their solution on top of the active layer. Therefore, they can be used as an interlayer in OSCs to provide a high power conversion efficiency (17.29%). Further studies reveal that these TOCs can not only reduce the work function of the silver electrode to provide better energy level alignment but also exhibit a significant n-doping effect with the non-fullerene acceptors to facilitate efficient electron extraction and transport. Our results demonstrate that TOCs as semiconductors have great potential application in OSCs.This 'How to' article explains how to change a suprapubic catheter in a safe, effective and supportive manner. Nurses undertaking this procedure must ensure they have the knowledge and skills to do so and work within the limits of their competence. The patient - and/or their carer where appropriate - should be involved in shared decision-making about the care of their suprapubic catheter and any catheter changes. This will increase the patient's confidence and acceptance of the suprapubic catheter and its function.

Smad3 phosphorylation This study aims to analyze the systematic reviews( SRs) of Qingkailing Injection,in order to provide reference for the clinical application of Qingkailing Injection and the development of relevant clinical practice guidelines. We searched CNKI,CBM,Wanfang,VIP,Pub Med,Cochrane Library and EMbase to collect SRs from the time of database establishment to August 2020. The eligible SRs were included according to the inclusion and exclusion criteria. AMSTAR 2 was used to assess the methodological quality. The diseases,drugs in combinations and results were extracted and analyzed. A total of 24 SRs were selected,including 10 for the treatment of acute cerebrovascular diseases,9 for respiratory infections,2 for viral hepatitis,1 for chronic obstructive pulmonary disease,and two for the adverse effects of Qingkailing Injection. Only three entries of AMSTAR 2 item were fully reported by over 70%,and the rest were reported by less than 70%,with no report about item 2,3 and 10. Twenty-nine outcome indicators were correlated with the included SRs,of which three mostly frequent outcomes were effectiveness,adverse reaction,and neurological deficit scores,showing a good efficacy of Qingkailing Injection. The common severe adverse reaction was anaphylaxis,and mild adverse reactions were skin and mucous membrane reactions. The most frequently combined drug was antibiotics,mainly Penicillin and Penicillin+Pioneeromycin. The existing evidences showed that the methodological quality of SRs of Qingkailing Injection needed to be improved and Qingkailing Injection had an obvious efficacy. However,the selection of outcome indicators for clinical trials and SRs shall be standardized,and the reporting of basic information,such as drug combination,shall be strengthened to provide more powerful clinical services.The present study evaluated the curative efficacy of Chinese herbal injection on unstable angina pectoris( UAP) by network Meta-analysis. The databases,including Pub Med,Cochrane Library,Web of Science,CNKI,CBM,VIP and Wanfang were searched for randomized controlled trial( RCT) of Chinese herbal injection in the treatment of UAP. All researchers independently screened the articles,extracted the data and evaluated the quality. Open BUGS and Stata were employed for the analysis of the trials that met the quality standards. Fifty-eight studies were finally included in this study,involving 20 intervention measures. In terms of the effective rate,16 injections such as Dengzhan Xixin Injection,Xuesaitong Injection and Danshen Injection combined with western medicine exhibited significant efficacy. In terms of ECG,Puerarin Injection,Ginkgo Leaf Extract and Dipyridamole Injection( GDI),Breviscapine Injection combined with western medicine were superior to western medicine. In terms of the reduction of the angina attack times,Sodium Tanshinone ⅡASulfonate Injection,GDI and Dazhu Hongjingtian Injection combined with western medicine showed better effects than western medicine. In terms of shortening the angina duration,Shenmai Injection combined with western medicine was superior to western medicine. As revealed by the results,Dengzhan Xixin Injection,Xuesaitong Injection,Danshen Injection,Breviscapine Injection,Danshen Ligustrazine Injection combined with western medicine displayed prominent curative efficacy,which were recommended for clinical application. Meanwhile,appropriate intervention measures should be selected according to individual conditions. Limited by the quality of the included trials,the conclusions still need to be further verified.The effect of Danhong Injection on the endogenous metabolites of rabbit platelets was analyzed by the liquid chromatography-mass spectrometry( LC-MS) based metabonomic approach. Anti-platelet aggregation was detected after Danhong Injection treatment and the changes of platelet metabolites were analyzed by metabonomics. Principal component analysis( PCA) and partial least squares discriminant analysis( PLS-DA) were performed to investigate the effect of Danhong Injection on endogenous metabolites of platelets,characterize the biomarkers,and explore the relevant pathways and the underlying mechanism. As demonstrated by the pharmacodynamic results,Danhong Injection of different doses and concentrations antagonized platelet aggregation in a dose-and concentration-dependent manner. In contrast to the control group,25 differential metabolites such as nicotinic acid,nicotinic acid riboside,and hypoxanthine were screened out after platelets were treated by Danhong Injection. These metabolites,serving as important biomarkers,were mainly enriched in the nicotinic acid-niacinamide metabolic pathway and purine metabolic pathway. This study explored the therapeutic mechanism of Danhong Injection from a microscopic perspective by metabonomics,which is expected to provide a new idea for the investigation of platelet-related mechanisms.This study aims to investigate metabolic activities of psoralidin in human liver microsomes( HLM) and intestinal microsomes( HIM),and to identify cytochrome P450 enzymes( CYPs) and UDP-glucuronosyl transferases( UGTs) involved in psoralidin metabolism as well as species differences in the in vitro metabolism of psoralen. First,after incubation serial of psoralidin solutions with nicotinamide adenine dinucleotide phosphate( NADPH) or uridine 5'-diphosphate-glucuronic acid( UDPGA)-supplemented HLM or HIM,two oxidic products( M1 and M2) and two conjugated glucuronides( G1 and G2) were produced in HLM-mediated incubation system,while only M1 and G1 were detected in HIM-supplemented system. The CLintfor M1 in HLM and HIM were 104. 3,and57. 6 μL·min~(-1)·mg~(-1),respectively,while those for G1 were 543. 3,and 75. 9 μL·min~(-1)·mg~(-1),respectively. Furthermore,reaction phenotyping was performed to identify the main contributors to psoralidin metabolism after incubation of psoralidin with NADPH-supplemented twesm and glucuronidation of psoralidinby liver microsomes showed significant species differences. In general,psoralidin underwent efficient hepatic and intestinal metabolisms. CYP1 A1,CYP2 C8,CYP2 C19,CYP2 D6 and UGT1 A1,UGT1 A7,UGT1 A8,UGT1 A9,UGT2 B7 were identified as the main contributors responsible for phase Ⅰ metabolism and glucuronidation,respectively. Rat and mini-pig were considered as the appropriate model animals to investigate phase Ⅰ metabolism and glucuronidation,respectively.This study aimed to investigate the effect and the possible mechanism of Shenlian( SL) extract on tumor necrosis factor-α( TNF-α)-induced ECV304 injury.
