Intrinsically high mobility and large absorption coefficient endow inorganic halide perovskites (IHPs) with great promise for high-performance photodetectors (PDs), which, however, are being hindered by the low carrier extraction and transport efficiency of the solution assembled films. Here, we report on a general strategy to enhance the film conductivity of perovskites that conductive nanonets were constructed with carbon nanotubes (CNTs) to provide fast carriers tracks. As a result, the CsPbBr3 nanosheet/CNT composite films exhibit high conductivity and the advantages are demonstrated by the high performances of corresponding planar PDs...

In this study, the bisulfite-peroxydisulfate system (S(IV)/PDS) widely used in polymerization was innovatively applied for organic contaminants degradation in water. The addition of S(IV) into PDS system remarkably enhanced the degradation efficiency of bisphenol A (BPA, a frequently detected endocrine disrupting chemical in the environments) from 17.0% to 84.7% within 360 min. The degradation efficiency of BPA in the S(IV)/PDS system followed pseudo-first-order kinetics, with rate constant values ranging from 0...

Importance: Periodic discharges (PDs) that do not meet seizure criteria, also termed the ictal interictal continuum, are pervasive on electroencephalographic (EEG) recordings after acute brain injury. However, their association with brain homeostasis and the need for clinical intervention remain unknown. Objective: To determine whether distinct PD patterns can be identified that, similar to electrographic seizures, cause brain tissue hypoxia, a measure of ongoing brain injury...

Phytoene synthase (Psy) and Phytoene desaturase (Pds) are the first two regulatory enzymes in the carotenoids biosynthetic pathway. The genes Psy and Pds are under transcriptional control in many photosynthetic organisms. In the present study, using quantitative real time- PCR (qRT-PCR), the effects of uncoated and gum-Arabic coated PbS nanoparticles (GA-coated PbS NPs) and light intensity on the mRNA levels of Pds were investigated. Relative to mRNA level of Pds at 100 µmol photon m-2 s-1 light intensity (control culture), 2...

Relational aggression (RAgg) is a form of behavior intended to damage the victim's social status or interpersonal relationships through the use of purposeful interpersonal manipulation or social exclusion (Archer & Coyne, 2005). RAgg is impairing, stable, and largely defined by dysfunctional patterns of interpersonal interactions-all of which invokes comparisons to personality and, more specifically, personality pathology. Leveraging research using the Five Factor Model (FFM) in personality disorder (PD) work, the present study aims to understand the personality context of RAgg by applying this FFM profile approach in 2 ways: (a) by compiling a personality profile of RAgg based on a thorough review of the relevant literature and (b) by compiling a personality profile of RAgg based on expert ratings (N = 19)...

BACKGROUND: Periodic discharges (PDs) are well established as either periodic lateralized epileptiform discharges (LPDs) or generalized discharges. However, PDs in the midline can currently not be adequately classified as they are not generalized and not lateralized. AIMS OF THE STUDY: To propose a modification of the current LPD classification. METHODS: We here present a paradigmatic case series of three adult patients with midline LPDs. RESULTS: In our patients, ictal electroencephalography (EEG) recordings revealed periodic epileptiform discharges in the midline region...

BACKGROUND: Biliary fistula (BF) occurs in 3-8% of patients following pancreaticoduodenectomy (PD). It usually pursues a benign course, but rarely may represent a life-threatening event. STUDY DESIGN: Data from 1618 PDs were collected prospectively. BF was defined as the presence of bile stained fluid from drains by post-operative day 3 and confirmed by sinogram in the majority of cases. Three classifications were validated. RESULTS: BF occurred in 58 (3...

The recent success of organometallic halide perovskites (OHPs) in photovoltaic devices has triggered lots of corresponding research and many perovskite analogues have been developed to look for devices with comparable performance but better stability. Upon the preparation of all inorganic halide perovskite nanocrystals (IHP NCs), research activities have soared due to their better stability, ultrahigh photoluminescence quantum yield (PL QY), and composition dependent luminescence covering the whole visible region with narrow line-width...

BACKGROUND: Virus-induced gene silencing (VIGS) has become a powerful tool for post-genomic technology in plant species. This is important, especially in select plants, such as the pepper plant, that are recalcitrant to Agrobacterium-mediated transformation. Although VIGS in plants has been widely employed as a powerful tool for functional genomics, scattering phenotypic effects by uneven gene silencing has been implemented in order to overcome challenges in experiments with fruit tissues...

Virus-induced gene silencing (VIGS) is a common reverse genetics strategy for characterizing the function of genes in plants. The detailed mechanism governing RNA silencing efficiency triggered by viruses is largely unclear. Here, we reveal that a petunia (Petunia hybrida) ocs element binding factor, PhOBF1, one of the basic leucine zipper (bZIP) transcription factors, was up-regulated by Tobacco rattle virus (TRV) infection. Simultaneous silencing of PhOBF1 and a reporter gene, phytoene desaturase (PDS) or chalcone synthase (CHS), by TRV-based VIGS led to a failure of the development of leaf photobleaching or the white-corollas phenotype...

We recently showed that Quantitative Perfusion SPECT (QPS), Emory Cardiac Toolbox (ECTb) and 4-Dimension-Myocardial SPECT (4DM) yielded discordant results in the assessment of perfusion defect size (PDS) in patients with known or suspected coronary artery disease. In this report, we examined the sources of variability in the measurement of PDS using ECTb (VarECTb), 4DM (Var4DM) and QPS (VarQPS) and found that gender is a source of variability in the assessment of PDS. In 120 patients, VarECTb was lower in men, compared with women, whereas Var4DM and VarQPS were similar between both genders...

Watermelon is an important and economical horticultural crop in China, where ~20% of the plants are grafted. The development of grafted watermelon fruit involves a diverse range of gene interactions that results in dynamic changes in fruit. However, the molecular mechanisms underlying grafting-induced fruit quality change are unclear. In the present study, we measured the lycopene content by high-performance liquid chromatography and used RNA-Seq (quantification) to perform a genome-wide transcript analysis of fruits from watermelon grafted onto pumpkin rootstock (pumpkin-grafted watermelon, PGW), self-grafted watermelon (SGW), and non-grafted watermelon (NGW)...
