Middle Meningeal Artery Embolization for Nonacute Subdural Hematoma.

Background: The effect of embolization of the middle meningeal artery in patients with subacute or chronic subdural hematoma is uncertain.

Methods: We performed a multicenter, open-label, randomized trial in China, involving patients with symptomatic nonacute subdural hematoma with mass effect. Patients were assigned to undergo burr-hole drainage or receive nonsurgical treatment at the surgeon's discretion, and patients in each group were then randomly assigned, in a 1:1 ratio, to undergo middle meningeal artery embolization with liquid embolic material or to receive usual care.

A PD-1-targeted, receptor-masked IL-2 immunocytokine that engages IL-2Rα strengthens T cell-mediated anti-tumor therapies.

The clinical use of interleukin-2 (IL-2) for cancer immunotherapy is limited by severe toxicity. Emerging IL-2 therapies with reduced IL-2 receptor alpha (IL-2Rα) binding aim to mitigate toxicity and regulatory T cell (Treg) expansion but have had limited clinical success. Here, we show that IL-2Rα engagement is critical for the anti-tumor activity of systemic IL-2 therapy.

Background: GLP-1 receptor agonists (GLP-1 RA) have been proven to treat several metabolic diseases; however, the effects of GLP-1 RA on polycystic ovary syndrome (PCOS) remain unclear. Here, we aimed to investigate whether semaglutide, a novel GLP-1 RA, could alleviate ovarian inflammation in PCOS mice.

Methods: Female C57BL/6J mice were subcutaneously injected with dehydroepiandrosterone for 21 days to establish the PCOS model.

Preparation of W-N-C single atom catalyst and Cu(HHTP) metal-organic framework dual-decorated graphene nanoplatelet flexible electrode arrays for the rapid detection of carbendazim in vegetables.

It is highly desirable to develop a low-cost and rapid detection method for trace levels of carbendazim fungicide residues, which would be beneficial for improving human health and mitigating environmental issues. Herein, isolated single tungsten atoms were implanted onto well-organized metal-organic framework (MOF)-derived N-doped carbons to form W-N-C single-site heterojunctions with ultrahigh electrocatalytic activity. The coupling of W-N-C with Cu(HHTP), an electronically conductive MOF with a large surface area and porous structure, exhibited enhanced electrocatalytic performance for the oxidation of carbendazim (CBZ) when they were used for decorating graphene nanoplatelet flexible electrode arrays fabricated via template-assisted scalable filtration.

Atomic insight into the effects of precursor clusters on monolayer WSe.

Two-dimensional (2D) transition metal dichalcogenides (TMDCs) have been attracting much attention due to their rich physical and chemical properties. At the end of the chemical vapor deposition growth of 2D TMDCs, the adsorption of excess precursor clusters onto the sample is unavoidable, which will have significant effects on the properties of TMDCs. This is a concern to the academic community.

W-N heteroatom-interface in melon carbon nitride/N-doped tungsten oxide Z-Scheme photocatalyst toward improved photocatalytic hydrogen generation activity.

The construction of heterointerface in photocatalyst is an efficient approach to boost the separation and utilization efficiency of charge carriers, which is challenging and crucial in photocatalysis. Here, the construction of melon-structured carbon nitride/N-doped WO (MCN/NW) heterojunction photocatalyst was achieved by a method of prealcoholysis combined with thermal polymerization, where N-doping of WO was achieved in-situ in the formation of heterojunction. The promoted charge separation efficiency was realized through the charge transfer from the conduction band of N-doped WO to the valence band of the MCN.

Theoretical prediction of superatom WSi-based catalysts for CO oxidation by NO.

Catalytic conversion of NO and CO into nonharmful gases is of great significance to reduce their adverse impact on the environment. The potential of the WSi superatom to serve as a new cluster catalyst for CO oxidation by NO is examined for the first time. It is found that WSi prefers to adsorb the NO molecule rather than the CO molecule, and the charge transfer from WSi to NO results in the full activation of NO into a physically absorbed N molecule and an activated oxygen atom that is attached to an edge of the hexagonal prism structure of WSi.

Nitrogen and water addition alters species diversity and interspecific relationship in a desert grassland.

Water and nitrogen (N) often affect plant species diversity and interspecific relationship among plant populations in global terrestrial ecosystems. However, the effects of water and N addition on plant diversity and interspecific relationship remain poorly understood. In the study, we designed a three-year field experiment in a desert grassland to assess the effect of increased water (natural +50 %) and N addition (10 g·N·m·a) on plant diversity and interspecific relationship.

This study was designed to evaluate the effect of warming ropivacaine on the ultrasound-guided subgluteal sciatic nerve block.

Molecular nitrogen induced structural evolution of single transition metal atoms supported by B/N co-doped graphene for enhanced nitrogen electroreduction performance.

The structural evolution of local coordination environments of single-atom catalysts (SACs) under reaction conditions plays an important role in the catalytic performance of SACs. Using density functional theory calculations, the possible structural evolution of transition metal single atoms supported by B/N codoped-graphene (TM-BN/G) under nitrogen reduction reaction (NRR) conditions is explored and the catalytic performance based on reconstructed SACs is theoretically evaluated. A novel nitrogen adsorption mode on TM-BN/G is discovered and the protonation of one of the N atoms results in the TM atoms binding with three N atoms, among which one associates with two B atoms (TM-NB/G).

Combined Treatment of Human Induced Pluripotent Stem Cell-Derived Cardiomyocytes and Endothelial Cells Regenerate the Infarcted Heart in Mice and Non-Human Primates.

Background: Remuscularization of the mammalian heart can be achieved after cell transplantation of human induced pluripotent stem cell (hiPSC)-derived cardiomyocytes (CMs). However, several hurdles remain before implementation into clinical practice. Poor survival of the implanted cells is related to insufficient vascularization, and the potential for fatal arrhythmogenesis is associated with the fetal cell-like nature of immature CMs.

Enhancing acid-base-water ternary aerosol nucleation with organic acid: a case of tartaric acid.

The new particle formation (NPF) process has been observed globally in clean and polluted environments, where the fundamental mechanisms leading to multicomponent aerosol formation remain elusive. Dicarboxylic acids play an important role in atmospheric NPF. In this study, theoretical calculations are performed to assess the effect of tartaric acid (TA) on the formation of clusters consisting of sulfuric acid (SA), ammonia (AM) or amines (methylamine or dimethylamine, MA/DMA) in the presence of water.

Origin of p-type conductivity in a WSe monolayer.

Transition-metal dichalcogenides have promising potentials for high-performance electronic and optoelectronic applications, which could be deeply influenced by defects, including native defects and dopants. Experiments to date have frequently reported p-type conductivity in the WSe monolayer, but the origin remains elusive. Here, using the first-principles calculations, we systematically investigate the point defects in the WSe monolayer and show that: (1) no intrinsic point defect is responsible for the p-type doping; (2) hydrogen interstitials (H) are possible sources for n-type conductivity; (3) oxygen substitution of Se (O) can greatly promote the formation of adjacent W vacancy (V), and finally make V relatively shallow acceptors by forming the defect complex O + V ( = 1 to 6).

Climate warming interacts with other global change drivers to influence plant phenology: A meta-analysis of experimental studies.

Shifts in plant phenology influence ecosystem structures and functions, yet how multiple global change drivers interact to affect phenology remains elusive. We conducted a meta-analysis of 242 published articles to assess interactions between warming (W) and other global change drivers including nitrogen addition (N), increased precipitation (IP), decreased precipitation (DP) and elevated CO (eCO ) on multiple phenophases in experimental studies. We show that leaf out and first flowering were most strongly affected by warming, while warming and decreased precipitation were the most pronounced drivers for leaf colouring.
