Deep learning models applied to digital histology can predict gene expression signatures (GES) and offer a low-cost, rapidly available alternative to molecular testing at the time of diagnosis. We optimized transformer-based models to infer GES results and applied this approach to pre-treatment H&E-stained biopsies from 1,940 breast cancer patients treated with neoadjuvant chemotherapy in clinical trial and real-world cohorts. The most predictive histology-derived GES for pathologic complete response (pCR) in the I-SPY2 trial was validated in four external cohorts: CALGB 40601, CALGB 40603, a trial of durvalumab plus CT, and standard-of-care CT-treated patients from the University of Chicago.

Nurses, as one of the major service stakeholders in this global agenda, needs to proactively seek role advancement and competency development in primary healthcare. This process can be facilitated by seeking a comprehensive understanding of the global landscape of nurses' roles and competencies in primary healthcare.

Effective learning involves not only the ability to quickly acquire knowledge and skills, but also the capacity to accurately monitor one's ongoing learning progress. The present research probed the relation between learning ability and monitoring accuracy. A meta-analysis (Study 1, = 2,406) counterintuitively found that individuals with superior learning ability exhibited slightly poorer monitoring accuracy (measured as the resolution of judgments of learning).
View Article and Find Full Text PDFAmorphous semiconductors have been proposed as ideal platforms for chemical mechanism (CM) based surface-enhanced Raman spectroscopy (SERS). Nevertheless, the high recombination rates of photo-generated excitons hinder further enhancement of their SERS performance. Here, a type-II CuO@amorphous FeO (a-FeO) core-shell p-n heterostructure is demonstrated as a novel platform for highly sensitive SERS detection.

Importance: OpenAI's recent large language model (LLM) o1 has dedicated reasoning capabilities, but it remains untested in specialized medical fields like ophthalmology. Evaluating o1 in ophthalmology is crucial to determine whether its general reasoning can meet specialized needs or if domain-specific LLMs are warranted.
Objective: To assess the performance and reasoning ability of OpenAI's o1 compared with other LLMs on ophthalmological questions.
Human umbilical cord mesenchymal stem cell extracellular vesicles (hucMSC-EVs) exhibit remarkable potential for alleviating type 2 diabetes mellitus (T2DM). However, the role of hucMSC-EVs in T2DM, particularly concerning oxidative damage to pancreatic β cells, remains underexplored. This study utilized a high-fat diet and streptozotocin (STZ)-induced T2DM mouse model and an STZ-induced INS-1 cell damage model to investigate the effects and mechanisms of hucMSC-EVs.

Nevertheless, the unsatisfying Raman enhancement exerts a substantial restriction on their practical applications. Herein, a strategy is demonstrated simultaneously integrating defect and heterojunction engineering within metallic TMC NSs for highly sensitive SERS detection of analytes.

Antibiotic-resistant bacteria produce some virulence factors as immune evasion molecules that interfere with a variety of innate immune defenses, which is associated with reduced levels of neutrophil recruitment. Antibiotics and neutrophils recruited by endogenous chemokines are not able to efficiently eliminate the bacteria at the site of infection. Here, a nano-chemoattractant (fZnCB) is developed with photodynamic therapy and neutrophil recruitment by a multi-component self-assembly strategy to coordinate benzoxaborole-modified Chlorin e6 (Ce6-BN) and formylated peptides (fMLFH) through Zn.

Objectives: We explored the potential use of MRI-CT three-dimensional (3D) reconstruction in the extraction of facial fillers.
Methods: In this investigation, pre and postoperative MRI-CT 3D reconstructions were performed on a cohort of 28 patients who underwent filler removal therapy. The efficiency of filler removal in critical facial regions was quantitatively assessed, and patient satisfaction was evaluated using a standardized Likert scale.
Polluted water poses a significant threat to human health and ecological balance, necessitating the development of efficient and cost-effective water purification technologies. This study synthesized a composite photocatalytic material (CMF@FeO-CN) using a microwave radiation synchrotron cooling technique. This material incorporates iron oxide-doped g-CN and in-situ micro-fibrillated cellulose, exhibiting high dispersion stability and magnetic recyclability.

A significant number of people with disabilities rely on assistive devices, yet these technologies often face limitations, including restricted functionality, inadequate user-centered design, and a lack of standardized evaluation metrics. While upper-limb prosthetics remain a key research focus, existing commercial solutions still fall short of meeting daily reliability and usability needs, leading to high abandonment rates. CYBATHLON integrates assistive technologies into daily living tasks, driving innovation and prioritizing user needs.

Biological wood oxidation (BWO) is a composting heat recovery system tailored for woody lignocellulose valorization, with the potential to generate sustainable and low-temperature heat. This study investigated the effects of feedstock particle sizing and periodic nutrient supplementation (PNS) on microbial activity and wood decomposition during BWO. Birch wood was processed into sawdust (<5 mm) and cubes of various diameters (5, 10, and 15 mm), incubated in batch-mode BWO reactors for 88 days, and periodically supplemented with a nutrient medium.

The effective bandwidth of each comb tooth is increased by over 10-fold. Wavelet high-pass filtering (WHPF) is employed to make the probability density functions (PDFs) of the chaotic signal's amplitude unbiased, achieving high symmetry with a skewness coefficient |S| of 0.

Microfibrillated cellulose (MFC) as an attractive green bio-based material has attracted widespread attention in recent years due to its non-toxicity, degradability, excellent performance, and high aspect ratio. In this study, the g-CN with a high nitrogen/carbon ratio was prepared as a catalyst through the self-polymerization of a nitrogen-rich precursor. The triazole groups at the edges of g-CN were proven to exhibit strong adsorption to biomass and strong alkalinity.

Aromatic amines are important commercial chemicals, but their carcinogenicity poses a threat to humans and other organisms, making their rapid quantitative detection increasingly urgent. Here, amorphous MoO (a-MoO) monolayers with localized surface plasmon resonance (LSPR) effect in the visible region are designed for the trace detection of carcinogenic aromatic amine molecules. The hot-electron fast decay component of a-MoO decreases from 301 fs to 150 fs after absorption with methyl orange (MO) molecules, indicating the plasmon-induced hot-electron transfer (PIHET) process from a-MoO to MO.

The eradication of osteomyelitis caused by methicillin-resistant Staphylococcus aureus (MRSA) poses a significant challenge due to its development of biofilm-induced antibiotic resistance and impaired innate immunity, which often leads to frequent surgical failure. Here, the design, synthesis, and performance of X-ray-activated polymer-reinforced nanotherapeutics that modulate the immunological properties of infectious microenvironments to enhance chemoradiotherapy against multidrug-resistant bacterial deep-tissue infections are reported. Upon X-ray radiation, the proposed polymer-reinforced nanotherapeutic generates reactive oxygen species and reactive nitrogen species.

Background: Until now, the analysis of microvascular networks in the reperfused ischemic brain has been limited due to tissue transparency challenges.
Methods: Using light sheet microscopy, we assessed microvascular network remodeling in the striatum from 3 hours to 56 days post-ischemia in 2 mouse models of transient middle cerebral artery occlusion lasting 20 or 40 minutes, resulting in mild ischemic brain injury or brain infarction, respectively. We also examined the effect of a clinically applicable S1P (sphingosine-1-phosphate) analog, FTY720 (fingolimod), on microvascular network remodeling.
