In this case, dual donor moieties and a single acceptor moiety are introduced to form two three-dimensional (3D) emitters, DM-BD1 and DM-BD2, which rely on spatial charge transfer (CT). Owing to the enforced face-to-face D/A/D pattern, effective CT interactions are realized, which lead to high photoluminescence quantum yields (PLQYs) of 94.2 % and 92.8 % for the two molecules, respectively. The resulting emitters exhibit small singlet-triplet energy splitting (ΔEST ) and fast reverse intersystem crossing (RISC) processes. Maximum external quantum efficiencies (EQEs) of 28.0 % and 26.6 % were realized for devices based on DM-BD1 and DM-BD2, respectively, which are higher than those of their D/A-type analogues.

To determine patient knowledge of the nature of their pain management in the ED.

This was a planned sub-study of data collected during a randomised, controlled trial of the nature of the informed consent process in a single ED. Patients aged ≥18 years, with a triage pain score of ≥4, were enrolled. Forty-eight hours post-ED discharge, patients were asked if they had declined analgesia or if a range of pain management options had been administered. The primary outcome was discordance between the patient report and the ED report (proportion of cases where these reports differed).

Outcome data were collected on 655 patients. There was significant discordance for all variables examined (P < 0.001). Discordance for patients declining analgesia was lowest at 8.9% (95% confidence interval [CI] 6.8-11.4). Discordance for administration of pain management 'other' than analgesia was highest at 32.6% (95% CI 29.0-36.4). Discordance for the administration of oral analgesia or 'any' analgesia was 17.1% (95% CI 14.3-20.3) and 14.4% (95% CI 11.8-17.3), respectively. For both of these outcomes, patients with chest pain and lower triage pain scores were more likely to report discordant responses. With the exception of 'other' pain management, smaller proportions of patients incorrectly reported not receiving management than incorrectly reporting that they did receive it.

Patients are often unaware of the nature of their pain management. They are most often unaware of management other than analgesia. Patients with chest pain and lower triage pain scores had the least knowledge of their pain management.

Pathologic sacroiliac (SI) joint changes on magnetic resonance imaging (MRI) are important for the classification of axial spondyloarthritis (SpA). In daily practice, radiologists play a major role in interpreting imaging findings. This study was undertaken to evaluate the impact of MRI SI joint findings on the identification of axial SpA by radiologists, in comparison to diagnosis by rheumatologists.

Patients age ≤45 years were prospectively included when referred for clinical suspicion of axial SpA and underwent a complete diagnostic evaluation including STIR- and T1-weighted MRI of the SI joint. Diagnosis made by an experienced rheumatologist with access to all relevant information was considered the gold standard. OSI-930 mw MRIs were evaluated by 2 experienced radiologists who were unaware of the clinical data, who indicated which MRI lesions were "critical" to the decision for or against axial SpA.

Of the 300 patients included, 132 (44%) were diagnosed as having axial SpA. Mean age was comparable between the SpA, the presence of BME does not necessarily confirm a diagnosis of axial SpA.

The MRI findings with the highest diagnostic value in patients in whom axial SpA is suspected are structural changes in the SI joint, alone or in combination with BME. Our findings indicate that while the absence of BME is usually not compatible with a diagnosis of axial SpA, the presence of BME does not necessarily confirm a diagnosis of axial SpA.

N

-methyladenosine (m

A) modification is one of the critical gene regulatory mechanisms implicated in cancer biology. However, the roles of m

A regulators in ovarian cancer are still poorly understood.

We integrated multiple databases including Gene Expression Omnibus (GEO), ROC Plotter, Kaplan-Meier Plotter, and Tumor Immune Estimation Resource (TIMER) to explore clinicopathological significance of m

A regulators in ovarian cancer.

We showed that alterations in the expression of m

A regulators were related to the malignancy and poor prognosis of ovarian cancer. We found decreased YTHDC1 and increased RBM15 expressions were associated with ovarian cancer cell metastases and HNRNPC was a predictor of paclitaxel resistance. Moreover, dysregulated m

A regulators were enriched in the activation of cancer-related pathways. Our results further demonstrated that the level of immune cell infiltration and the expression of various immune gene markers were closely associated with the expressions of specific m

A regulators (RBM15B, ZC3H13, YTHDF1, and IGF2BP1).

Our study establishes a new prognostic profile of ovarian cancer patients based on m

A regulators, and highlights the potential roles of m

A regulators in ovarian cancer development.

Metallic group-5 TMDs have been demonstrated to be effective catalysts for the HER in acidic media, making affordable real proton exchange membrane water electrolysers. Their key-plus relies on the fact that both their basal planes and edges are catalytically active for the HER. In this work, the 6R phase of TaS2 is "rediscovered" and engineered. A liquid-phase microwave treatment is used to modify the structural properties of the 6R-TaS2 nanoflakes produced by liquid-phase exfoliation. The fragmentation of the nanoflakes and their evolution from monocrystalline to partly polycrystalline structures improve the HER-activity, lowering the overpotential at cathodic current of 10 mA cm-2 from 0.377 to 0.119 V. Furthermore, 6R-TaS2 nanoflakes act as ideal support to firmly trap Pt species, which achieve a mass activity (MA) up 10 000 A gPt-1 at overpotential of 50 mV (20 000 A gPt-1 at overpotentials of 72 mV), representing a 20-fold increase of the MA of Pt measured for the Pt/C reference, and approaching the state-of-the-art of the Pt mass activity.
