The recombinant EG003 and its catalytic domain, EG003A, were successfully expressed and characterized.

Anchorable Polymers Enabling Ultra-Thin and Robust Hole-Transporting Layers for High-Efficiency Inverted Perovskite Solar Cells.

Currently, the development of polymeric hole-transporting materials (HTMs) lags behind that of small-molecule HTMs in inverted perovskite solar cells (PSCs). A critical challenge is that conventional polymeric HTMs are incapable of forming ultra-thin and conformal coatings like self-assembly monolayers (SAMs), especially for substrates with rough surface morphology. Herein, we address this challenge by designing anchorable polymeric HTMs (CP1 to CP5).

In-Situ Cross-Linked Polymers for Enhanced Thermal Cycling Stability in Flexible Perovskite Solar Cells.

Flexible perovskite solar cells (FPSCs) are a promising emerging photovoltaic technology, with certified power conversion efficiencies reaching 24.9 %. However, the frequent occurrence of grain fractures and interface delamination raises concerns about their ability to endure the mechanical stresses caused by temperature fluctuations.

Energy management strategy for methanol hybrid commercial vehicles based on improved dung beetle algorithm optimization.

In order to solve the problem of poor adaptability and robustness of the rule-based energy management strategy (EMS) in hybrid commercial vehicles, leading to suboptimal vehicle economy, this paper proposes an improved dung beetle algorithm (DBO) optimized multi-fuzzy control EMS. First, the rule-based EMS is established by dividing the efficient working areas of the methanol engine and power battery. The Tent chaotic mapping is then used to integrate strategies of cosine, Lévy flight, and Cauchy Gaussian mutation, improving the DBO.

Boosting Hot Electron Generation in Energy Center Embedded Metal-Organic Frameworks for Photocatalysis.

The ligands in metal-organic framework (MOF) play as light absorption center and transfer photogenerated electrons to metal node through ligand-to-metal charge transfer (LMCT) during photocatalysis, and energy utilization efficiency is strongly restricted by the light inertness of ligands. Herein, a ligand updating strategy is proposed by inserting energy centers to MOFs to activate the inherent ligands, realizing boosting hot electron generation and photocatalytic activities via the cascaded proceeding of energy transfer and charge transfer. By taking PCN-777 (a zeotype mesoporous Zr-containing MOF) as an example, this study shows that the embedded energy center of 1-pyrenecarboxylic acid (PCA) can activate the inherent ligand of PCN-777 through triplet-triplet energy transfer, where triplet excitons would dissociate into photocarriers migrating to the Zr metal cluster via LMCT process.

Construction and validation of a senescence-related gene signature for early prediction and treatment of osteoarthritis based on bioinformatics analysis.

The aim of this study is to screen key target genes of osteoarthritis associated with aging and to preliminarily explore the associated immune infiltration cells and potential drugs. Differentially expressed senescence-related genes (DESRGs) selected from Cellular senescence-related genes (SRGs) and differentially expressed genes (DEGs) were analyzed using Gene Ontology enrichment, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways and protein-protein interaction networks. Hub genes in DESRGs were selected based on degree, and diagnostic genes were further screened by gene expression and receiver operating characteristic (ROC) curve.

Salt added at the table, APOE genotype and incident dementia.

Background: The frequency of salt added at the table (i.e., to food after it has been prepared, during consumption) could reflect an individual's long-term dietary preference and habitual intake in Western countries.

Deciphering endocrine function of adipose tissue and its significant influences in obesity-related diseases caused by its dysfunction.

Current research has found that adipose tissue is not only involved in energy metabolism, but also a highly active endocrine organ that secretes various adipokines, including adiponectin, leptin, resistin and apelin, which are involved in the regulation of physiology and pathology of tissues and organs throughout the body. With the yearly increasing incidence, obesity has become a risk factor for a variety of pathological changes, including inflammation and metabolic syndrome in various system (endocrine, circulatory, locomotor and central nervous system). Thus these symptoms lead to multi-organ dysfunctions, including the heart, liver, kidneys, brain and joints.

Buried hole-selective interface engineering for high-efficiency tin-lead perovskite solar cells with enhanced interfacial chemical stability.

Mixed Sn-Pb perovskites are attracting significant attention due to their narrow bandgap and consequent potential for all-perovskite tandem solar cells. However, the conventional hole transport materials can lead to band misalignment or induce degradation at the buried interface of perovskite. Here we designed a self-assembled material 4-(9H-carbozol-9-yl)phenylboronic acid (4PBA) for the surface modification of the substrate as the hole-selective contact.

Sustained effects of repeated levodopa (L-DOPA) administration on reward circuitry, effort-based motivation, and anhedonia in depressed patients with higher inflammation.

Inflammatory biomarkers like C-reactive protein (CRP) are elevated in a subset of patients with depression and have been associated with lower functional connectivity (FC) in a ventral striatum (VS) to ventromedial prefrontal cortex (vmPFC) reward circuit and symptoms of anhedonia. Evidence linking these relationships to the effects of inflammation on dopamine is consistent with our recent findings that acute levodopa (L-DOPA) increased VS-vmPFC FC in association with deceased anhedonia in depressed patients with higher but not lower CRP (>2 versus ≤ 2 mg/L). To determine whether repeated L-DOPA administration caused sustained effects on FC and behavior in these patients, medically stable depressed outpatients with CRP > 2 mg/L and anhedonia (n = 18) received one week of three doses of L-DOPA (150-450 mg/day/week with carbidopa) or placebo in a randomized order.

Tc/Y radiolabeled biodegradable gel microspheres for lung shutting fraction assessment and radioembolization in hepatocellular carcinoma theranostics.

Transarterial radioembolization (TARE) is a well-established clinical therapy for the treatment of patients with intermediate to advanced hepatocellular carcinoma (HCC) or those who are ineligible for radical treatment. However, commercialized radioactive microspheres still have some issues, such as high density, complicated preparation, non-biodegradability. Furthermore, the use of different radioactive microspheres during TARE and lung shunt fraction assessment has led to inconsistencies in biodistribution in certain cases.

Liver Transplantation for Hepatocellular Carcinoma: An Expanding Cornerstone of Care in the Era of Immunotherapy.

Liver transplantation (LT) has been accepted as a cornerstone of care in hepatocellular carcinoma (HCC) for almost three decades. In recent years, its role has been evolving to include patients with disease burden beyond the widely used Milan criteria. The integration of dynamic biomarkers such as alpha-fetoprotein together with downstaging approaches and tumor evolution after enlistment has allowed the selection of patients most likely to benefit, resulting in 5-year survival rates greater that 70%.

Impact of intraoperative hypotension during laparoscopic liver resection on postoperative complications including acute kidney injury.

Background: Postoperative acute kidney injury is associated with an increase in hospital length of stay and mortality. Intraoperative hemodynamics and fluid management may contribute to acute kidney injury. The aim of this study is to evaluate the association between intraoperative duration of hypotension with adverse events after laparoscopic liver resection.

MIF promotes Th17 cell differentiation in rheumatoid arthritis through ATF6 signal pathway.

Rheumatoid arthritis (RA) is a common autoimmune disease that can lead to irreversible joint damage when it occurs, but its pathogenesis has not yet been elucidated. In this study, we explored the roles of macrophage migration inhibitory factor (MIF), endoplasmic reticulum stress (ER stress), and Th17 cells in the pathogenesis of RA. We have preliminarily confirmed that MIF expression in CD4T cells and the proportion of Th17 cells are increased in active RA patients.
