Small upconversion-ruthenium nanohybrids for cancer theranostics.

Photoresponsive drug delivery systems have great potential for improved cancer therapy. However, most of the currently available drug-delivery nanosystems are relatively large and require light excitation with low tissue penetration. Here, we designed a near infrared responsive drug delivery system by loading [Ru(terpyridine)(dipyridophenazine)(HO)] (Ru(tpy)DPPZ) in azobenzene-modified mesoporous silica coated NaGdF:Nd/Yb/Tm upconversion nanoparticles (azo-mSiO-UCNPs).

Serum amyloid P (PTX2) attenuates hepatic fibrosis in mice by inhibiting the activation of fibrocytes and HSCs.

Background: Liver fibrosis is caused by chronic toxic or cholestatic liver injury. Fibrosis results from the recruitment of myeloid cells into the injured liver, the release of inflammatory and fibrogenic cytokines, and the activation of myofibroblasts, which secrete extracellular matrix, mostly collagen type I. Hepatic myofibroblasts originate from liver-resident mesenchymal cells, including HSCs and bone marrow-derived CD45+ collagen type I+ expressing fibrocytes.

Association of radiation-induced normal tissue toxicity with a high genetic risk for rheumatoid arthritis.

Purpose: Overlapping genes are involved with rheumatoid arthritis (RA) and DNA repair pathways. Therefore, we hypothesised that patients with a high polygenic risk score (PRS) for RA will have an increased risk of radiotherapy (RT) toxicity given the involvement of DNA repair.

Methods: Primary analysis was performed on 1494 prostate cancer, 483 lung cancer and 1820 breast cancer patients assessed for development of RT toxicity in the REQUITE study.

Fluid-structure-growth modeling in ascending aortic aneurysm: capability to reproduce a patient case.

Predicting the evolution of ascending aortic aneurysm (AscAA) growth is a challenge, complicated by the intricate interplay of aortic geometry, tissue behavior, and blood flow dynamics. We investigate a flow-structural growth and remodeling (FSG) model based on the homogenized constrained mixture theory to simulate realistic AscAA growth evolution. Our approach involves initiating a finite element model with an initial elastin insult, driven by the distribution of Time-Averaged Wall Shear Stress (TAWSS) derived from computational fluid dynamics simulations.

IFN-α neutralizing antibodies distinguish LADA from early-onset type 1 diabetes.

Context: Autoantibodies against IFN-α (AAb-IFN-α) might be associated with the less aggressive autoimmunity in latent autoimmune diabetes in adults (LADA) compared to early-onset type 1 diabetes (T1D).

Objective: To investigate the presence and clinical relevance of the positivity to AAb-IFN-α in people with LADA compared to T1D.

Research Design And Methods: Serum levels of AAb against IFN-α isoforms were measured using a cell-based approach in 41 subjects with LADA and in 90 subjects with T1D.

Obesity and Chronic Inflammation: Implications for Rheumatoid Arthritis, Spondyloarthritis, and Ulcerative Colitis.

Background: Immune-mediated inflammatory diseases (IMIDs) are a group of chronic conditions characterized by dysregulated immune responses and persistent inflammation. Rheumatoid arthritis (RA), spondyloarthritis (SpA), and ulcerative colitis (UC) exemplify prominent IMIDs, each presenting unique challenges for their management, that impact patient's quality of life (QoL). Obesity, marked by persistent low-grade inflammation, influences the progression, response to treatment, and clinical management of patients with RA, SpA, and UC.

Isolated Temporomandibular Arthritis as Presentation of Juvenile Idiopathic Arthritis.

Involvement of the temporomandibular joint (TMJ) in patients with juvenile idiopathic arthritis (JIA) has been increasingly reported, affecting up to 87% of cases. This involvement generally occurs after the diagnosis of JIA has been established; however, in the authors' cases, as in a few others documented in the literature, patients presented with isolated TMJ arthritis as the sole joint involvement. The authors performed a narrative literature review on TMJ involvement in JIA and reported 2 cases that presented with isolated TMJ arthritis as the initial manifestation of JIA.

Analytical characteristics and performance of a new hs-cTnI method: a multicenter-study.

Objectives: The present multicenter study was designed to evaluate the analytical performance and the 99th percentile value of the reference healthy population i.e., 99th percentile upper reference limit of the MAGLUMI CLIA high-sensitivity cardiac troponin I (hs-cTnI) method.

Global Burden of Gallbladder Cancer Attributable to Modifiable Risk Factors.

Gallbladder cancer (GBC) is a highly lethal and often overlooked malignancy increasingly affecting young adults. This study quantified the global proportion of GBC cases attributable to 10 key modifiable risk factors, employing Monte Carlo simulations and estimates from field-wide systematic review and meta-analysis. Approximately three-quarters of global GBC cases are attributable to key modifiable factors (74.

Photocatalytic Semiconductor-Metal Hybrid Nanoparticles: Single-Atom Catalyst Regime Surpasses Metal Tips.

Semiconductor-metal hybrid nanoparticles (HNPs) are promising materials for photocatalytic applications, such as water splitting for green hydrogen generation. While most studies have focused on Cd containing HNPs, the realization of actual applications will require environmentally compatible systems. Using heavy-metal free ZnSe-Au HNPs as a model, we investigate the dependence of their functionality and efficiency on the cocatalyst metal domain characteristics ranging from the single-atom catalyst (SAC) regime to metal-tipped systems.

Creation of an FeP Schreibersite Density Functional Tight Binding Model for Astrobiological Simulations.

The mineral schreibersite, e.g., FeP, is commonly found in iron-rich meteorites and could have served as an abiotic phosphorus source for prebiotic chemistry.

Solvent Engineering-Enabled Surface Defect Passivation in Cu2ZnSn(S,Se)4 Solar Cells with Low Open-Circuit Voltage Losses and Improved Carrier Lifetime.

The efficiency of earth-abundant kesterite Cu2ZnSn(S,Se)4 (CZTSSe) solar cells has been lagging behind the Shockley-Queisser limit primarily due to the presence of deep-level defects. These deep-level defects cause critical issues such as short carrier diffusion length, significant band tailing, and a large open-circuit voltage (VOC) deficit, ultimately leading to low device efficiency. To address these issues, we propose a post-fabrication defect healing strategy by dip-coating the CZTSSe film in dimethylformamide (DMF) solvent.

Structures and Rotational Constants of Monocyclic Monoterpenes at DFT Cost by Pisa Composite Schemes and Vibrational Perturbation Theory.

The structures and rotational constants of prototypical monocyclic terpenes and terpenoids have been analyzed by a general computational strategy based on recent Pisa composite schemes (PCS) and vibrational perturbation theory at second order (VPT2). Concerning equilibrium geometries, a one-parameter empirical correction is added to bond lengths obtained by the revDSD-PBEP86 double hybrid functional in conjunction with a slightly modified cc-pVTZ-F12 basis set. The same functional and basis set give accurate harmonic frequencies, whereas the cheaper B3LYP hybrid functional in conjunction with a double-ζ basis set is employed to compute the semidiagonal cubic force constants needed to obtain vibrational corrections to the rotational constants in the framework of the VPT2 model.
