-Loaded Easily Injectable Hydrogel Promotes Endometrial Repair via Long-Term Retention and Microenvironment Modulation.

Regeneration of the injured endometrium, particularly the functional layer, is crucial for the prevention of uterine infertility. At present, clinical treatment using sodium hyaluronate hydrogel injection is limited by its relatively low fluidity, short-term retention, and insufficient bioactive ingredients, so it is necessary to develop an advanced healing-promoting hydrogel. The modulation of the microenvironment by presents a bioactive component that can facilitate the regeneration of the functional layer.

Three-dimensional glenohumeral relationship in cuff tear arthropathy and its correlation with the type of cuff tear.

Mixed-Dimensional Semiconductors-Based Ternary Circuits with Tunable Negative Transconductance Characteristics.

Multivalued logic (MVL) systems, in which data are processed with more than two logic values, are considered a viable solution for achieving superior processing efficiency with higher data density and less complicated system complexity without further scaling challenges. Such MVL systems have been conceptually realized by using negative transconductance (NTC) devices whose channels consist of van der Waals (vdW) heterojunctions of low-dimensional semiconductors; however, their circuit operations have not been quite ideal for driving multiple stages in real circuit applications due to reasons such as a reduced output swing and poorly defined logic states. Herein, we demonstrate ternary inverter circuits with near rail-to-rail swing and three distinct logic states by employing vdW p-n heterojunctions of single-walled carbon nanotubes (SWCNT) and MoS where the SWCNT layer completely covers the MoS layer.

MXene Hollow Microsphere-Boosted Nanocomposite Electrodes for Thermocells with Enhanced Thermal Energy Harvesting Capability.

Thermal energy, constantly being produced in natural and industrial processes, constitutes a significant portion of energy lost through various inefficiencies. Employing the thermogalvanic effect, thermocells (TECs) can directly convert thermal energy into electricity, representing a promising energy-conversion technology for efficient, low-grade heat harvesting. However, the use of high-cost platinum electrodes in TECs has severely limited their widespread adoption, highlighting the need for more cost-effective alternatives that maintain comparable thermoelectrochemical performance.

Modulating Built-In Electric Field Via N-Doped Carbon Dots for Robust Oxygen Evolution at Large Current Density.

Constructing a built-in electric field (BIEF) within heterostructures has emerged as a compelling strategy for advancing electrocatalytic oxygen evolution reaction (OER) performance. Herein, the p-n type nanosheet array heterojunction NiP-NCDs-Co(OH)-NF are successfully prepared. The variation in interaction affinity between nitrogen within N-doped carbon dots (NCDs) and Ni/Co induces charge redistribution between Co and Ni in the NiP-NCDs-Co(OH)-NF-3 heterostructure, thereby enhancing the intensity of the BIEF, facilitating electron transfer, and markedly improving OER activity.

Clinical and pathological characteristics of HR+ breast cancer with HER2 low and HER2(0) expression: exploring endocrine therapy sensitivity.

Background: The clinical significance of human epidermal growth factor receptor 2 (HER2) low and HER2(0) expression in hormone receptor-positive (HR+) breast cancer patients remains uncertain. This study aimed to explore the clinical and pathological characteristics, prognosis, and endocrine therapy (ET) sensitivity among HR+ breast cancer patients with HER2 low and HER2(0) expression.

Methods: We conducted a retrospective analysis of 390 HR+, HER2-negative breast cancer patients who underwent radical surgery at The First Affiliated Hospital of Bengbu Medical University between December 2014 and December 2017.

The Significant Role of Atopic Skin Diathesis in Prurigo Nodularis.

Objectives: Atopic skin plays a significant etiological role in the development of prurigo nodularis (PN). In addition to atopic dermatitis (AD), atopic skin diathesis without eczema can also contribute to the development of PN due to its association with itching. This study aims to evaluate PN in terms of AD/atopic skin diathesis, associated comorbidities, and clinical findings.

Impact of surgery versus follow-up on psychological distress in patients with indeterminate pulmonary nodules: A prospective observational study.

Purpose: To investigate whether surgery is more effective than follow-up in reducing psychological distress for patients with observable indeterminate pulmonary nodules (IPNs) and to assess if psychological distress can serve as a potential surgical indication for IPNs.

Methods: This prospective observational study included 341 patients with abnormal psychometric results, as measured by the Hospital Anxiety and Depression Scale (HADS). Of these, 262 patients opted for follow-up and 79 chose surgery.

An Exploratory Study of PN HPT for Treating Postsurgical Atrophic and Depressed Scars.

Background: Postsurgical atrophic scars tend to respond poorly to treatments, especially non-energy-based ones. Hydrophilic PN HPT (Polynucleotides High Purification Technology) injected intradermally is a non-energy-based option with an immediate volume-enhancing effect that indirectly improves the fibroblast synthesis of collagen and extracellular matrix. The PN HPT ingredient has the further benefit of a dermal "priming" effect that enhances the efficacy of other scar treatments.

Untargeted metabolomics was performed on serum samples of 5,004 children aged 6-59 months, a subset of participants from the Brazilian National Survey on Child Nutrition (ENANI-2019).

Performance of an Algorithm Grading Surgery-Related Adverse Events According to the Clavien-Dindo Classification.

Objective: To assess performance of an algorithm for automated grading of surgery-related adverse events (AEs) according to Clavien-Dindo (C-D) classification.

Summary Background Data: Surgery-related AEs are common, lead to increased morbidity for patients, and raise healthcare costs. Resource-intensive manual chart review is still standard and to our knowledge algorithms using electronic health record (EHR) data to grade AEs according to C-D classification have not been explored.

Exploring environmental risk in soils: Leveraging open data for non-sampling assessment?

Soil contamination by heavy metals (HM) is a critical area of research. Traditional methods involving sample collection and lab analysis are effective but costly and time-consuming. This study explores whether geostatistical analysis with GIS and open data can provide a faster, more precise, and cost-effective alternative for HM contamination assessment without extensive sampling.

Force Nanoscopy Demonstrates Stress-Activated Adhesion between Iron-Regulated Surface Determinant Protein B and Host Toll-like Receptor 4.

The iron-regulated surface determinant protein B (IsdB) has recently been shown to bind to toll-like receptor 4 (TLR4), thereby inducing a strong inflammatory response in innate immune cells. Currently, two unsolved questions are (i) What is the molecular mechanism of the IsdB-TLR4 interaction? and (ii) Does it also play a role in nonimmune systems? Here, we use single-molecule experiments to demonstrate that IsdB binds TLR4 with both weak and extremely strong forces and that the mechanostability of the molecular complex is dramatically increased by physical stress, sustaining forces up to 2000 pN, at a loading rate of 10 pN/s. We also show that TLR4 binding by IsdB mediates time-dependent bacterial adhesion to endothelial cells, pointing to the role of this bond in cell invasion.

Exosome markers, CD63 and CD81, belong to the tetraspanin family and are expressed in solid tumors. It has been reported that these tetraspanin family members are prognostic factors in some cancers. However, the expression of CD63 and CD81 in pathological breast cancer specimens has not been reported.

Anisotropically Epitaxial P-N Heterostructures Actuating Efficient Z-Scheme Photocatalytic Water Splitting.

Crafting anisotropically epitaxial p-n heterostructures with Z-scheme charge transmission is a promising avenue toward excellent photocatalytic efficiency, yet the large lattice mismatch and diverse crystal growth habits between components have often arisen as a big challenge to this goal. Here, anisotropically epitaxial p-n heterostructures with 19.8% lattice mismatch are obtained via a dynamics-mediated seeded growth tactic under reaction temperature as low as 60 °C.
