Synthetic hydroxyapatite (HA) materials with antibacterial and biocompatible properties have potential for biomedical applications. The application of various computational methods is highly relevant for the optimal development of modern materials. In this work, we used molecular docking to determine the binding constants of tetracycline (TET) and quercetin (QUE) with hydroxyapatite and compared them to experimental data of the adsorption of tetracycline (TET) and quercetin (QUE) on the HA surface.

Organic-inorganic formamidinium lead triiodide (FAPbI) hybrid perovskite quantum dots (QDs) have garnered considerable attention in the photovoltaic field due to their narrow bandgap, exceptional environmental stability, and prolonged carrier lifetime. Unfortunately, their insulating ligands and surface vacancy defects pose significant obstacles to efficient charge transfer across device interfaces. In this work, an electrostatic harmonization strategy at the interface using a donor-acceptor dipole molecular attachment to achieve enhanced charge separation capabilities on the QD surface is ventured.

Small

January 2025

Jiangxi Province Key Laboratory of Functional Crystalline Materials Chemistry, School of Chemistry and Chemical Engineering, Jiangxi University of Science and Technology, 156 Ke Jia Avenue, Ganzhou, 341000, P. R. China.

Incorporating a third component through ternary copolymerization strategy has proven to be a promising and effective approach for further improving the device performance of polymer donors. However, terpolymer donors typically exhibit negative effects on molecular stacking and weaken charge transport due to the irregular distribution of the polymer skeleton. Herein, two terpolymers PBBQ-5 (5% ff-Qx) and PBBQ-10 (10% ff-Qx) are developed by introducing the difluoro-2-(3-hexyldecyloxy) quinoxaline (ff-Qx) to the main chain of PM6.

The effective prevention and treatment of anastomotic leakage after intestinal anastomosis for colorectal diseases is still a major clinical challenge. In order to assist intestinal anastomosis healing and avoid anastomotic leakage caused by high tension, low blood supply or infection, we designed a double-layer nanofiber intestinal anastomosis scaffold, which was composed of electrospun PTMC/PHA nanofibers as the main layer, and electrospun PVA/OHA-Gs nanofibers with antibacterial properties as the antibacterial surface layer. This double-layer scaffold has good toughness, its maximum tensile force value could reach 8 N, elongation could reach 400 %, and it has hydrophilic properties, and its contact angle was about 60°.

(Gabriel); the Department of Distributed Learning and Rural Initiatives, Cumming School of Medicine, University of Calgary, Calgary, Alta. (Perez, Johnston)

Background: Because tertiary centres are generally situated at urban sites, it is unclear whether patients in rural areas have the same access to surgical services that patients in urban areas do. We sought to map the North American evidence landscape of how rurality affects access to medically indicated surgeries and identify system-, patient-, and provider-level barriers that preclude urban-comparable care.

Methods: We carried out a systematic search adhering to PRISMA for Scoping Reviews methodology across PubMed, MEDLINE, Scopus, and Web of Science, encompassing literature from the last 26 years (January 2023).

A number of studies have tested the factor structure of the suggested ICD-11 symptom criteria for PTSD and complex PTSD (CPTSD) across various trauma populations, finding support for two different models in line with the ICD-11 theoretical rationale. Here, we aim to explore the factor structure of the Danish version of the International Trauma Questionnaire (ITQ) by testing two alternative factor models that have previously gained support in a large sample of treatment-seeking veterans. Treatment-seeking Danish soldiers and veterans ( = 599) recruited from the Military Psychology Department in the Danish Defence completed the International Trauma Questionnaire (ITQ).

In a prospective longitudinal study with 218 Parkinson's disease (PD) patients in the discovery cohort and 84 in the validation cohort, we aimed to identify novel blood biomarkers predicting disability milestones in PD. Through Least Absolute Shrinkage and Selection Operator-Cox (Lasso-Cox) regression, developed nomogram predictive model and Linear mixed-effects models, we identified low level of plasma fibronectin (pFN) as one of the best-performing risk markers in predicting disability milestones. A low level of pFN was associated with a short milestone-free survival period in PD.

Key Laboratory of Targeted Intervention of Cardiovascular Disease, Collaborative Innovation Center for Cardiovascular Disease Translational Medicine, School of Basic Medical Sciences, Nanjing Medical University, Nanjing, Jiangsu, 211166, China.

Mitochondrial dysfunction is a key factor in exacerbating pressure overload-induced cardiac hypertrophy and is linked to increased morbidity and mortality. ECSIT, a crucial adaptor for inflammation and mitochondrial function, has been reported to express multiple transcripts in various species and tissues, leading to distinct protein isoforms with diverse subcellular localizations and functions. However, whether an unknown ECSIT isoform exists in cardiac cells and its potential role in regulating mitochondrial function and pathological cardiac hypertrophy has remained unclear.

Surface Doping to Suppress Iodine Ion Migration for Stable FAPbI Perovskite Quantum Dot Solar Cells.

Small

December 2024

Dalian National Laboratory for Clean Energy, iChEM, Dalian Institute of Chemical Physics, Chinese Academy of Sciences, 457 Zhongshan Road, Dalian, 116023, P. R. China.

Formamidine lead iodide (FAPbI) quantum dots (QDs) have attracted great attention as a new generation of photovoltaic material due to their long carrier diffusion length, benign ambient stability, and light-harvesting ability. However, its large surface area with inherent thermodynamic instability and highly defective ionic termination are still major obstacles to fabricating high-performance devices. Herein, a metallic ion dopant is developed to post-treat FAPbI QDs immediately after their fabrication by using a metal-glutamate salt solution.

In this study, composite biscuits were produced by combining wheat flour (WF) with different proportions of malted pearl millet (MPM) flour (8%, 16%, 24%, and 32%) and orange peel (OP) flour (2%, 4%, 6%, and 8%), using 100% WF as a control. The investigation covered the functional properties, viscosity, and thermal properties of the flours, along with the proximate composition, antioxidant, physical properties, color attributes, and microbial quality of the composite biscuits. As MPM and OP flour (OPF) contents increased, water absorption capacity, dispersibility, and foaming power increased, while the viscosities of both hot and cold pastes decreased.
