Unconventional Hexagonal Close-Packed High-Entropy Alloy Surfaces Synergistically Accelerate Alkaline Hydrogen Evolution.

Accelerating the alkaline hydrogen evolution reaction (HER), which involves the slow cleavage of HO-H bonds and the adsorption/desorption of hydrogen (H*) and hydroxyl (OH*) intermediates, requires developing catalysts with optimal binding strengths for these intermediates. Here, the unconventional hexagonal close-packed (HCP) high-entropy alloy (HEA) atomic layers are prepared composed of five platinum-group metals to enhance the alkaline HER synergistically. The breakthrough is made by layer-by-layer heteroepitaxial deposition of subnanometer RuRhPdPtIr HEA layers on the HCP Ru seeds, despite the thermodynamic stability of Rh, Pd, Pt, and Ir in a face-centered cubic (FCC) structure except for Ru.

Origin of the High Catalytic Activity of MoS in Na-S Batteries: Electrochemically Reconstructed Mo Single Atoms.

Room-temperature sodium-sulfur (RT Na-S) batteries with high energy density and low cost are considered promising next-generation electrochemical energy storage systems. However, their practical feasibility is seriously impeded by the shuttle effect of sodium polysulfide (NaPSs) resulting from the sluggish reaction kinetics. Introducing a suitable catalyst to accelerate conversion of NaPSs is the most used strategy to inhibit the shuttle effect.

Presence of Sonographic Secondary Signs Without Visualization of Appendix Is Indicative of Appendicitis in Children Younger Than 5 Years.

Purpose: Diagnosis of acute appendicitis is more difficult in children aged 0-4 years due to atypical clinical presentation, leading to delay in diagnosis and higher incidence of complications. Nonvisualization of the appendix on ultrasound increases diagnostic challenge. We examined the utility of standardized reporting of sonographic secondary signs of appendicitis in children younger than 5 years with nonvisualization of the appendix.

Adaptation mechanism of clam Ruditapes philippinarum under polycyclic aromatic hydrocarbon stresses: Accumulation and excretion.

Persistent organic pollutants (POPs) are easily accumulated in organisms due to its high lipophilicity. Bivalves are still one of the marine invertebrates with high species diversity despite experiencing with environmental pollution. However, studies investigating the adaptation mechanisms of bivalves towards POPs have been lacking.

A canonical protein complex controls immune homeostasis and multipathogen resistance.

The calcium (Ca) sensor ROD1 (RESISTANCE OF RICE TO DISEASES1) is a master regulator of immunity in rice. By screening suppressors of mutants, we show that ROD1 governs immune homeostasis by surveilling the activation of a canonical immune pathway. Mutations in (), (), (), and () all abolish enhanced disease resistance of plants.

The impact of recipient hypernatremia on pediatric liver transplantation outcomes.

In pediatric liver transplants, dysnatremias have been found to have an impact on pretransplant and posttransplant outcomes. However, much of the current literature has focused on waitlist survival, secondary organ damage, and dysnatremia in donors rather than in recipients. To understand the effect of recipient immediate pretransplant hypernatremia on posttransplant mortality, we conducted a multivariable retrospective review analyzing data from 8011 pediatric patients undergoing liver transplantation provided by the United Network for Organ Sharing (UNOS).

Case report: Microsurgical resection of a giant triple dumbbell shaped jugular foramen Schwannoma via retrosigmoid and transcervical approach.

The surgical management of extensive jugular foramen schwannomas presents a formidable challenge, aiming for gross total resection while minimizing complications. Here, we present a case with giant triple dumbbell-shaped jugular Foramen Schwannoma. A 45-year-old male with a one-year history of a left neck mass underwent surgery.

Association Between Workplace Violence and Post-Traumatic Stress Disorder Among Healthcare Workers in China, 2020 to 2023.

This is the first study in China to investigate the prevalence of workplace violence (WPV) and its long-term association with post-traumatic stress disorder (PTSD) among healthcare workers. Conducted across various time points from March 27, 2020, to April 10, 2023, the research employed a four-wave repeated cross-sectional design involving 14,993 healthcare workers from 32 provincial administrative regions across the country. Nurses accounted for 34.

Overexpression of SlATG8f gene enhanced autophagy and pollen protection in tomato under heat stress.

Autophagy is a mechanism for the degradation of cellular components in eukaryotes and plays a critical role in plant responses to abiotic stress. As a core member of the autophagy process, ATG8's role in how plants respond to heat stress remains unclear. To investigate the response of the tomato autophagy core member ATG8f to heat stress, we studied the key gene ATG8f and generated tomato lines overexpressing SlATG8f using the recombinant expression vector pBWA(V)HS.

Fine mapping of QGPC.caas-7AL for grain protein content in bread wheat.

A major stable QTL, QGPC.caas-7AL, for grain protein content of wheat, was narrowed down to a 1.82-Mb inter on chromosome 7AL, and four candidate genes were predicated.

Anesthesia/surgery leads to blood-brain barrier disruption via the transcellular and paracellular pathways, and postoperative delirium-like behavior: A comparative study in mice of different ages.

Aims: Postoperative delirium (POD) is a common complication of anesthesia and surgery, with a higher incidence in elderly patients. Disruption of the blood-brain barrier (BBB) is considered one of the key mechanisms underlying POD. Therefore, the present study aimed to investigate the effects of different BBB permeability alteration pathways on POD in mice of various ages.

[Chen Zhiqian's Thoughts on Public Health in the 1920s].

During his studies at the Peking Union Medical College (1921-1929),Chen Zhiqian formed his thoughts on public health under the influences of modern medical education and the advanced thinking of the times,which laid an ideological foundation for his later engagement in rural health care and reflected the medical progress in China at that time.In the 1920s,Chen Zhiqian's thoughts on public health mainly encompassed five aspects.First,health was a cornerstone of the country's wealth and people's well-being.

Prenatal Exposure to MAM Impairs mPFC and Hippocampal Inhibitory Function in Mice during Adolescence and Adulthood.

Neurodevelopmental abnormalities are considered to be one of the important causes of schizophrenia. The offspring of methylazoxymethanol acetate (MAM)-exposed mice are recognized for the dysregulation of neurodevelopment and are well-characterized with schizophrenia-like phenotypes. However, the inhibition-related properties of the medial prefrontal cortex (mPFC) and hippocampus throughout adolescence and adulthood have not been systematically elucidated.

"Nano knife" for efficient piezocatalytic inactivation of amoeba spores and their intracellular bacteria: Synergetic effect between physical damage and chemical oxidation.

Microbial interactions between infectious agents severely interfere with the disinfection process, and current disinfection methods are unable to effectively inactivate intracellular pathogens, posing a new threat to drinking water safety. In this study, we first reported the high efficiency of piezocatalysis in inactivating amoebae and their intracellular bacteria. Results showed that the inactivation rates of the MoS/rGO piezocatalytic system for amoebic spores and their intracellular bacteria were 4.

Comprehensive Understanding of Laboratory Evolution for Food Enzymes: From Design to Screening Innovations.

In the field of food processing, enzymes play a pivotal role in improving product quality and flavor, and extending shelf life. However, the exposure of traditional food enzymes to high temperatures during processing often leads to a decrease in activity or even inactivation, limiting the effectiveness of their application under high-temperature conditions. Therefore, the modification of thermostability and activity of enzymes to adapt to extreme conditions through protein engineering has become a key way to improve the efficiency and economic benefits of industrial production.
