Heterogeneous single-atom systems demonstrate potential to break performance limitations of single-atom catalysts through synergy interactions. The synergy in heterogeneous single atoms strongly dependes on their anchoring sites. Herein, we reveal the site-specific synergy in heterogeneous single atoms for oxygen evolution.

The hypoxic microenvironment is one of the typical features of tumor tissues and has an important impact on the activity of multiple signaling pathways. It is of great significance to study the effects of hypoxia on the pathophysiological processes and molecular mechanisms of HCC.

Design: This was a cross-sectional study carried out following the Strengthening the Reporting of Observational Studies in Epidemiology checklist.
Setting: This study was conducted in two hospitals in Beijing from October 2021 to November 2022.
Aim: To analyse how refined living arrangements, in the context of digital access, affect elderly healthcare resource utilisation and satisfaction with healthcare needs.
Design: A prospective cohort study. The study reporting is conformed to the STROBE checklist.
Aim(s): To investigate the correlation between compassion Fatigue, emotional labour and missed nursing care among intensive care unit nurses.
Design: A cross-sectional design.
Methods: Data were collected from two hospitals in Shandong Province, China, from July to August 2024.
Aim: To investigate the correlation between intensive care unit (ICU) nurses' demographic characteristics, teamwork, moral sensitivity and missed nursing care.
Background: Teamwork, moral sensitivity and missed nursing care are important health challenges among ICU nurses. Clarifying the relationship between variables is benefit to improve the quality of patients care.
Background: The post-ICU home recovery period requires patients and caregivers to confront recovery challenges and adopt coping strategies as a family dyad, necessitating effective dyadic interaction patterns. Existing qualitative research shows that the dyads face interactive or independent challenges and employs varying coping strategies, which may include strong communication or, conversely, avoidance. However, a single qualitative study alone might offer limited generalizability, and there is a lack of broader, more nuanced understanding about the recovery challenge and copings among ICU survivors and caregivers.

Background: Post-traumatic growth is common in patients facing maintenance hemodialysis. However, studies tend to focus on these patients as individuals rather than as part of a couple.
Designing efficient and durable electrocatalysts for oxygen reduction reaction (ORR) is essential for proton exchange membrane fuel cells (PEMFCs). Platinum-based catalysts are considered efficient ORR catalysts due to their high activity. However, the degradation of Pt species leads to poor durability of catalysts, limiting their applications in PEMFCs.

The testis is the main organ responsible for sperm production, and the egg-laying cycle in geese is a complex physiological process that demands precise orchestration of hormonal cues and cellular events within the testes, however, the seasonal changes in the transcriptomic and proteomic profiles of goose testicles remain unclear. To explore various aspects of the mechanisms of the seasonal cyclicity of testicles in different goose breeds, in this study, we used an integrative transcriptomic and proteomic approach to screen the key genes and proteins in the testes of 2 goose males, the Hungarian white goose and the Wanxi white goose, at 3 different periods of the laying cycle: beginning of laying cycle (BLC), peak of laying cycle (PLC), and end of laying cycle (ELC).

Methods: Nude mouse tumor-bearing assay was used to detect tumor progression. Levels of Mannose/CD68 and CD34/Mannose within these samples and the concentrations of Mannose and inducible Nitric Oxide Synthase (iNOS) in macrophages were quantified using immunofluorescence techniques.
Lysozyme is often used as a feed additive to act as an antibacterial protein that boosts the immune system of livestock and poultry while protecting against pathogens. To investigate the effects of recombinant human lysozyme (rhLYZ) from Pichia pastoris and chlortetracycline on broiler chicken's production performance, antioxidant characteristics, and intestinal microbiota, a total of 200, 1-d-old male Arbor Acres broiler chickens (46.53 ± 0.

To investigate the effect of genetic selection on meat quality in ducks, twenty of each fast growth ducks (LCA) and slow growth ducks (LCC) selected from F6 generation of Cherry Valley ducks (♂) x Liancheng white ducks (♀) were analyzed for carcass characteristics, meat quality (physicochemical and textural characteristics), amino acid and fatty acid profiles at 7 wk. Results showed that live body weight, slaughter weight, eviscerated yield and abdominal fat percentage of LCA were significantly higher than those in LCC ducks (P < 0.01).

In this study, a noble-metal-free metallic VSe nanosheet was incorporated on g-CN to serve as an electron capture and transfer center, activating surface active sites for highly efficient and selective CO photoreduction. X-ray photoelectron spectroscopy (XPS), soft X-ray absorption spectroscopy (sXAS), and femtosecond transient absorption spectroscopy (fs-TAS) unveiled that VSe could capture electrons, which are further transferred to the surface for activating active sites.

Methods: An IIMs cohort in southeastern China was constructed, including 504 adult IIMs patients who met the inclusion and exclusion criteria, and were hospitalized at four divisions of the First Affiliated Hospital, Zhejiang University School of Medicine from January 1st 2018 to April 30st 2022. After dividing patients into the training cohort and the validation cohort, risk factors for MI were identified through least absolute shrinkage and selection operator regression and multivariate logistic regression.
The catalytic performance of single-atom catalysts was strictly limited by isolated single-atom sites. Fabricating high-density single atoms to realize the synergetic interaction in neighbouring single atoms could optimize the adsorption behaviors of reaction intermediates, which exhibited great potential to break performance limitations and deepen mechanistic understanding of electrocatalysis. However, the catalytic behavior governed by neighbouring single atoms is particularly elusive and has yet to be understood.
