Revealing the momentum-resolved electronic structure of infinite-layer nickelates is essential for understanding this class of unconventional superconductors but has been hindered by the formidable challenges in improving the sample quality. In this work, we report the angle-resolved photoemission spectroscopy of superconducting LaSrNiO films prepared by molecular beam epitaxy and in situ atomic-hydrogen reduction. The measured Fermi topology closely matches theoretical calculations, showing a large Ni [Formula: see text]-derived Fermi sheet that evolves from hole-like to electron-like along and a three-dimensional (3D) electron pocket centered at the Brillouin zone corner.

These air-stable compounds crystallize as triply cation-ordered variants of the 6H perovskite structure. This structure contains octahedra that share a common face to form MRhCl dimers that are arranged on a two-dimensional triangular network.

This study evaluates a 7T deep-learning (DL)-based image reconstruction using a deep neural network trained on 7T data, applied to T2-weighted turbo spin echo imaging. Raw k-space data from 30 consecutive clinical 7T brain MRI patients was reconstructed using both DL and standard methods.

In addition, it is also challenging to selectively convert inert C(sp)-H bonds into value-added chemicals. Herein, robust 3D COFs, USTB-28-M (M=Co, Ni, Cu), have been polymerized from the nucleophilic aromatic substitution reaction of -symmetric 2,3,6,7,14,15-hexahydroxyltriptycene with -symmetric hexadecafluorophthalocyanine (MPcF) under solvothermal conditions.

Introducing a third metallic element into the γ-brass lattice further perturbs the catalytic active site ensembles. Here, we introduce coinage metallic elements M (M = Cu, Ag, and Au) into the Pd-Zn γ-brass phase and investigate the site occupation factors of each element in the γ-brass lattice.

Studies indicate that taking low-dose aspirin before the 16th week of pregnancy may prevent approximately 70 % of PE cases, highlighting the importance of predicting PE. Cell-free RNA (cf-RNA) exhibits significant changes in the maternal peripheral blood during early pregnancy, making cf-RNA analysis a promising and less invasive method for predicting PE.

However, mechanistic insights into such catalytic systems remain ambiguous, limiting the understanding of sulfur electrochemistry and retarding the rational design of available catalysts. Herein, we systematically explore the polysulfide adsorption-conversion essence via a geminal-atom model system to understand the catalyst roles toward an expedited SRR.

Recent discoveries of several new species, including the zoonotic Langya virus, have revealed much higher antigenic diversity than currently characterized. Here, to explore the limits of structural and antigenic variation in HNVs, we construct an expanded, antigenically diverse panel of HNV fusion (F) and attachment (G) glycoproteins from 56 unique HNV strains that better reflects global HNV diversity.

We developed a novel adeno-associated virus 5 gene therapy (AAV5-GLA) expressing human alpha-galactosidase A (GLA) under the control of a novel, small and strong, liver-restricted promoter. We assessed the preclinical potential of AAV5-GLA for treating Fabry disease, an X-linked hereditary metabolic disorder resulting from mutations in the gene encoding GLA that lead to accumulation of the substrates globotriaosylceramide and globotriaosylsphingosine, causing heart, kidney, and central nervous system dysfunction. Effects of intravenously administered AAV5-GLA were evaluated in (1) GLA-knockout mice aged 7-8 weeks (early in disease) and 20 weeks (nociception phenotype manifestation) and (2) cynomolgus macaques during an 8-week period.

In addition, cells of the same type can assume different states within an individual's body during their lifetime. Understanding the complexities of the proteome in the context of a human organism and its many potential states is a necessary requirement to understanding human biology, but these complexities can neither be predicted from the genome, nor have they been systematically measurable with available technologies.

Nickel presents a promising candidate for alkaline HOR; yet, its practical application is hampered by the intrinsically sluggish activity and poor stability. Herein, a series of Ni-based metals (NiMo, NiCo, NiW and Ni) are electrodeposited as model catalysts to systematically explore the alkaline HOR by considering the role of adsorbed hydroxyl (OH).

To investigate in vivo mechanisms of Fyn-driven neurodegeneration, we built a zebrafish neural-specific Gal4:UAS model of constitutively active FynY531F signaling. Using in vivo live imaging, we demonstrated that neural FynY531F expression leads to dopaminergic neuron loss and mitochondrial aggregation in 5 day larval brain.

This study aimed to investigate the changes in diffusion MRI measures related to the glymphatic function in children with RE.
Materials And Methods: A total of thirty-eight children with RE and thirty-six demographically matched healthy children were enrolled in the study.
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.
Background: Subacute and chronic subdural hematomas are common and frequently recur after surgical evacuation. The effect of adjunctive middle meningeal artery embolization on the risk of reoperation remains unclear.
Methods: In a prospective, multicenter, interventional, adaptive-design trial, we randomly assigned patients with symptomatic subacute or chronic subdural hematoma with an indication for surgical evacuation to undergo middle meningeal artery embolization plus surgery (treatment group) or surgery alone (control group).
Rationale And Objectives: Metabolic dysfunction-associated fatty liver disease (MAFLD) is linked to an increased risk of cardiovascular events. Our study sought to determine the impact of MAFLD on both the anatomy and function of coronary plaques.
Materials And Methods: A total of 203 participants (including 728 plaques) with suspected coronary artery disease (CAD) who underwent coronary CT angiography (CCTA) and abdominal ultrasound were prospectively enrolled.
Background & Aims: Surgery is the only curative therapeutic option for resectable extrahepatic cholangiocarcinoma, but recurrence is common, and prognosis is poor. There is an unmet clinical need for improved decision-making regarding adjuvant chemotherapy (ACT). Herein, we evaluated the usefulness of monitoring longitudinal circulating tumor DNA (ctDNA) for molecular residual disease (MRD) in patients from the STAMP trial, which compares the efficacy of adjuvant capecitabine (CAP) vs.

The SF3b complex is a crucial unit of the spliceosome, but model organisms generated through genetic modification of the complex do not perfectly mimic the phenotype of spliceosomopathies. Since the phenotypes are suggested to be determined by the extent of spliceosome dysfunction, an alternative experimental system that can seamlessly control SF3b function is needed.
