Charge Transfer Effect in Layered Cathodes Through MEMS-Based In Situ TEM Studies.

The irreversible lattice oxygen release is the primary issue in layered oxide cathodes which is generally attributed to a consecutive phase transition with less lattice oxygen content. Herein, an anomalous metal segregation pathway is observed in oxygen vacancy defective layered cathodes, which happens far before the onset of phase transitions. The correlation of electron energy loss spectroscopy indicates that an early charge transfer from oxygen 2p to Mn 3d orbital is responsible.

Path analysis of COVID-19 cognition, social support, and mental health of pregnant women with interventional prenatal diagnosis during the COVID-19 pandemic based on structural equation modeling.

This study aims to investigate the relationship between Corona Virus Disease 2019 (COVID-19) cognition, social support, and mental health among pregnant women proposed for undergoing interventional prenatal diagnosis in Sichuan Province during the COVID-19 pandemic. A total of 2270 pregnant women (2232 valid) who were proposed to undergo interventional prenatal diagnosis at a tertiary hospital prenatal diagnosis center in Sichuan Province from January to December 2022 were selected by Convenience sampling and surveyed using a self-administered general information questionnaire, social support rating scale, mental health questionnaire (including: Self-Rating Anxiety Scale, Self-Rating Depression Scale), and self-administered COVID-19 cognition questionnaire. Structural equation modeling showed that social support negatively predicted anxiety (β = -0.

Mechanically Robust Current Collector with Gradient Lithiophilicity Induced by Spontaneous Lithium Ion Diffusion for Stable Lean-Lithium Metal Batteries.

Lean-lithium metal batteries represent an advanced version of the anode-free lithium metal batteries, which can ensure high energy density and cycling stability while addressing the safety concerns and the loss of energy density caused by excessive lithium metal. Herein, a mechanically robust carbon nanotube framework current collector with gradient lithiophilicity is constructed for a lean-lithium metal battery. Using the physical vapor deposition method, precise prelithiation of a carbon nanotube framework is achieved, eliminating its irreversible capacity, retaining the porous structure in the framework, and inducing the gradient lithiophilicity formation due to spontaneous lithium ion diffusion.

The implementation and effect evaluation of AIDET standard communication health education mode under the King theory of goal attainment: A randomized control study.

Background: This research addresses inadequate understanding of interventional prenatal diagnosis, preoperative anxiety psychological problems in pregnant women undergoing interventional prenatal diagnosis, proposing a health education mode combined AIDET standard communication and King's theory of goal attainment approach to potentially improve health education outcomes, anxiety psychological problems, and patient satisfaction.

Methods: A convenient sampling method was used to select a total of 300 pregnant women who were ready to undergo interventional prenatal diagnosis. They were randomly divided into a implementation group and a control group, with 150 pregnant women in each group.

Case Report: Cystinosis in a Chinese Child With a Novel CTNS Pathogenic Variant.

Objective: To report a rare case of cystinosis with a novel CTNS pathogenic variant in the Chinese population.

Methods: Retrospective analysis of the clinical manifestations, laboratory results, and gene detection data of a child with cystinosis.

Results: A Chinese Zang ethnic girl could not stand or walk until 3 years old, with additional symptoms including a loss of appetite.

A Case Report of Central Nervous System Graft-Versus-Host Disease and Literature Review.

As an adverse immune phenomenon, graft-versus-host disease often occurs after allogeneic hematopoietic stem cell transplantation. The incidence of acute and chronic graft-versus-host disease is about 40-60% and the mortality rate can reach 15%, which is a potentially fatal disease. There are rare GvHD cases involving the central nervous system.

Regional Features of MuSK Antibody-Positive Myasthenia Gravis in Northeast China.

To summarize the characteristics of muscle-specific receptor tyrosine kinase antibody-positive myasthenia gravis (MuSK-MG) in Northeast China. We retrospectively collected 183 confirmed MG patients and divided them into three groups based on the type of serum antibodies: MuSK-MG (14 cases), acetylcholine receptor (AChR)-MG (130 cases), and double-seronegative (DSN)-MG (39 cases). The clinical, diagnostic, therapeutic, and prognosis data were analyzed.

Intermittent alien hand syndrome caused by Marchiafava-Bignami disease: A case report.

Rationale: Alien Hand syndrome (AHS) is characterized in most patients by seemingly purposeful, involuntary movements of the extremities. It is not well known among physicians on account of its diverse clinical manifestations.

Patient Concerns: We present a 57-year-old Chinese man who could not stop or turn himself around as he involuntarily and uncontrollably walked forward, which had happened frequently in the month prior to treatment.

RNA-seq analysis of the hypothalamic transcriptome reveals the networks regulating physiopathological progress in the diabetic GK rat.

The Goto-Kakizaki (GK) rat is an animal model of non-obese type 2 diabetes (T2D). The GK rat was generated through the introduction of various genetic mutations from continuous inbreeding; these rats develop diabetes spontaneously. The mutated genes in GK rats may play key roles in the regulation of diabetes.
