Stem cells are of great importance in the maintenance and regeneration of tissues, with Forkhead box O (FoxO) proteins emerging as pivotal regulators of their functions. However, the precise impact of FoxO proteins on stem cell behavior within regenerative environments remains ambiguous. Planarians, renowned for their abundance of adult stem cells (neoblasts), serve as an excellent model for investigating the dynamics of stem cells during regeneration.

Cretaceous coastal mountain building and potential impacts on climate change in East Asia.

Sci Adv

December 2024

Key Laboratory of Paleomagnetism and Tectonic Reconstruction, Ministry of Natural Resources, Institute of Geomechanics, Chinese Academy of Geological Sciences, Beijing 100081, China.

Crustal thickness and elevation variations control mountain building and climate change at convergent margins. As an archetypal Andean-type convergent margin, eastern Asia preserves voluminous magmas ideal for quantifying these processes and their impacts on climate. Here, we use Sr/Y and Ce/Y proxies to show that the crust experienced alternating thickening and thinning during the Late Mesozoic.

Key Laboratory of Synthetic and Natural Functional Molecule of the Ministry of Education, Shaanxi Key Laboratory of Physico-Inorganic Chemistry, College of Chemistry and Materials Science, Northwest University, Xi'an, 710127, P.R. China.

Efficient separation of acetylene (CH) from carbon dioxide (CO) and ethylene (CH) is a significant challenge in the petrochemical industry due to their similar physicochemical properties. Pore space partition (PSP) has shown promise in enhancing gas adsorption capacity and selectivity by reducing pore size and increasing the density of guest binding sites. Herein, we firstly employ the 2D→3D polycatenation strategy to construct a PSP metal-organic framework (MOF) Ni-dcpp-bpy, incorporating functional N/O sites to enhance CH purification.

A novel multiscale model is formulated to examine the co-evolution among behavioral dynamics, disease transmission dynamics and viral dynamics, in which perceived risk act as a bridge for realizing the bidirectional coupling of between-host dynamics and within-host dynamics. The model is validated by real data and exhibits rich dynamic behaviors including the periodic oscillations of the solutions, the discordance of transmission dynamics and viral dynamics. It is observed that new infections may increase with improving treatment efficacy, which may reveal the hidden mechanisms why it is hard to eliminate HIV/AIDS infection only with the strategy of treatment.

Electric Field-Induced Synergetic Enhancement of Local Hydroxyl Concentration and Photogenerated Carrier Density for Removal of CO in Electrocatalytic Formic Acid Oxidation.

Small

January 2025

Key Laboratory of Synthetic and Natural Functional Molecule Chemistry of Ministry of Education, College of Chemistry and Material Science, Northwest University, Xi'an, 710127, China.

Direct formic acid fuel cell (DFAFC) is an efficient power generation device, due to its high energy density, low fuel crossover and low emission. However, the anodic reaction of DFAFC, formic acid oxidation (FAOR), inevitably proceeds through an indirect pathway, adsorbing carbon monoxide intermediate (CO), resulting in a rapid decline of activity for FAOR. Therefore, effectively removing CO is the key to the development of DFAFC.

p-n-Type LaCoO/NiFe LDH Heterostructures for Enhanced Photogenerated Carrier-Assisted Electrocatalytic Oxygen Evolution Reaction.

ACS Appl Mater Interfaces

December 2024

Xi'an Key Laboratory of Functional Supramolecular Structure and Materials, College of Chemistry and Material Science, Northwest University, Xi'an 710127, China.

The oxygen evolution reaction (OER) poses a significant kinetic challenge for various critical energy conversion and storage technologies including electrocatalytic water splitting and metal-air batteries. In this study, a LaCoO/NiFe layered double hydroxide (LDH) catalyst was synthesized through the growth of n-type NiFe LDH on the surface of the p-type LaCoO semiconductor, resulting in a p-n heterostructure for a photogenerated carrier-assisted electrocatalytic OER (PCA-eOER). The alignment of their band structures facilitates the formation of an internal electric field at the heterojunction interface, which promotes the creation of oxygen vacancies and enhances electron transport.

Type III collagen, a fundamental constituent of the extracellular matrix (ECM), is extensively utilized across the biomedicine, tissue engineering, and cosmetic industries because of its exceptional biocompatibility and biodegradability. Despite its widespread application, traditional methods of collagen production are often hindered by the limit yield, potential immunogenicity, and batch-to-batch variability. In the present study, we describe a synthetic biological approach for expressing full-length recombinant type III collagen (RCIII) in the Komagataella phaffii system.

Many of the complex behaviours of humans involve the production of nonadjacent dependencies between sequence elements, which in part can be generated through the hierarchical organization of sequences. To understand how these structural properties of human behaviours evolved, we can gain valuable insight from studying the sequential behaviours of nonhuman animals. Among the behaviours of nonhuman apes, tool use has been hypothesised to be a domain of behaviour which likely involves hierarchical organization, and may therefore possess nonadjacent dependencies between sequential actions.
