Revealing Intrinsic Free Charge Generation: Promoting the Construction of over 19% Efficient Planar p-n Heterojunction Organic Solar Cells.

Due to high binding energy and extremely short diffusion distance of Frenkel excitons in common organic semiconductors at early stage, mechanism of interface charge transfer-mediated free carrier generation has dominated the development of bulk heterojunction (BHJ) organic solar cells (OSCs). However, considering the advancements in materials and device performance, it is necessary to reexamine the photoelectric conversion in current-stage efficient OSCs. Here, we propose that the conjugated materials with specific three-dimensional donor-acceptor conjugated packing potentially exhibit distinctive charge photogeneration mechanism, which spontaneously split Wannier-Mott excitons to free carriers in pure phases.

Mesenchymal stromal cell-derived extracellular vesicles as nanotherapeutics for concanavalin a-induced hepatitis: modulating the gut‒liver axis.

Background: As cell-free nanotherapeutics, extracellular vesicles derived from mesenchymal stem cells (MSC-EVs) have shown potential therapeutic action against liver diseases. However, their effects on autoimmune hepatitis (AIH) are not yet well understood.

Methods And Results: In this study, we utilized a well-established concanavalin A (Con A)-induced fulminant hepatitis mouse model to investigate the effects of MSC-EVs on AIH.

subsp. CKDB001 Ameliorates Metabolic Complications in High-Fat Diet-Induced Obese Mice.

Background/objectives: Functional probiotics, particularly subsp. CKDB001, have shown potential as a therapeutic option for metabolic dysfunction-associated steatotic liver disease (MASLD). However, their effects have not been confirmed in in vivo systems.

Assessing the use of the Index of Consciousness (IoC) as a monitoring tool for the sedative effects of ciprofol during general anesthesia induction: a prospective observational study.

Background: We investigated the consistency and accuracy of the Index of Consciousness (IoC) and the Bispectral Index (BIS) in monitoring the sedative effect of ciprofol during the induction of general anesthesia. There is extensive literature that reports good consistency and correlations between the IoC1 and the BIS in reflecting the sedation levels induced by propofol and sevoflurane but not by ciprofol.

Objective: The aim was to compare the consistency and accuracy of the IoC and BIS in monitoring the sedative effect of ciprofol during the induction of general anesthesia.

Medication Withdrawal With Normal or Near-normal Histology in Ulcerative Colitis is Associated With Clinical Relapse.

Goals: We sought to understand the clinical course and risk of dysplasia in persons with UC who achieve near or complete normalization of histology.

Background: Histologic remission and normalization in ulcerative colitis (UC) is associated with improved clinical outcomes. We sought to understand the clinical course and risk of dysplasia in persons with UC who achieve near or complete normalization of histology.
