Study on the pathway of energy transition in Inner Mongolia under the "dual carbon" goal.

As an important strategic energy base in China, Inner Mongolia's energy exports are dominated by coal and electricity. Under the background of "double carbon" target, the energy transition of Inner Mongolia is of great significance to China's energy security and carbon emission reduction. Based on the energy policy simulation model (EPS model), this paper explores the path of energy transition in Inner Mongolia by constructing the scenarios of developing renewable energy, developing CCS technology and carbon pricing, and simulating the policy situation based on the reality of Inner Mongolia and the energy transition experience of developed countries and regions.

Highly Dispersion CuO QDs Decorated BiWO S-Scheme Heterojunction for Enhanced Photocatalytic Water Oxidation.

Developing suitable photocatalysts for the oxygen evolution reaction (OER) is still a challenging issue for efficient water splitting due to the high requirements to create a significant impact on water splitting reaction kinetics. Herein, -type BiWO with flower-like hierarchical structure and -type CuO quantum dots (QDs) are coupled together to construct an efficient S-scheme heterojunction, which could enhance the migration efficiency of photogenerated charge carriers. The electrochemical properties are investigated to explore the transportation features and donor density of charge carriers in the S-scheme heterojunction system.

Construction of plasmonic Bi/Bismuth oxycarbonate/Zinc bismuth oxide ternary heterojunction for enhanced charge carrier separation and photocatalytic performances.

In this work, a novel plasmonic ternary Bi/Bismuth oxycarbonate/Zinc bismuth oxide (Bi-BiOCO-ZnBiO) is synthesized synergistically by a one-step hydrothermal method. The results show that the metallic Bi spheres and ZnBiO nanoparticles are uniformly distributed on the surface of flower-like BiOCO layer. Compared with the bare ZnBiO and Bi-BiOCO, the ternary Bi-BiOCO-ZnBiO heterojunction displays a significantly improved solar energy harvesting efficiency and enhanced photocatalytic degradation activity for environmental organic pollutants.

A biomarker-authenticated model of schizophrenia implicating NPTX2 loss of function.

Schizophrenia is a polygenetic disorder whose clinical onset is often associated with behavioral stress. Here, we present a model of disease pathogenesis that builds on our observation that the synaptic immediate early gene NPTX2 is reduced in cerebrospinal fluid of individuals with recent onset schizophrenia. NPTX2 plays an essential role in maintaining excitatory homeostasis by adaptively enhancing circuit inhibition.

VAMP-2 is a surrogate cerebrospinal fluid marker of Alzheimer-related cognitive impairment in adults with Down syndrome.

Background: There is an urgent need for objective markers of Alzheimer's disease (AD)-related cognitive impairment in people with Down syndrome (DS) to improve diagnosis, monitor disease progression, and assess response to disease-modifying therapies. Previously, GluA4 and neuronal pentraxin 2 (NPTX2) showed limited potential as cerebrospinal fluid (CSF) markers of cognitive impairment in adults with DS. Here, we compare the CSF profile of a panel of synaptic proteins (Calsyntenin-1, Neuroligin-2, Neurexin-2A, Neurexin-3A, Syntaxin-1B, Thy-1, VAMP-2) to that of NPTX2 and GluA4 in a large cohort of subjects with DS across the preclinical and clinical AD continuum and explore their correlation with cognitive impairment.

Effects of Ultrasonic Surface Rolling Processing and Subsequent Recovery Treatment on the Wear Resistance of AZ91D Mg Alloy.

Resting-State Functional Connectivity Is Associated With Cerebrospinal Fluid Levels of the Synaptic Protein NPTX2 in Non-demented Older Adults.

Intrinsic functional connectivity of large-scale brain networks has been shown to change with aging and Alzheimer's disease (AD). These alterations are thought to reflect changes in synaptic function, but the underlying biological mechanisms are poorly understood. This study examined whether Neuronal Pentraxin 2 (NPTX2), a synaptic protein that mediates homeostatic strengthening of inhibitory circuits to control cortical excitability, is associated with functional connectivity as measured by resting-state functional magnetic resonance imaging (rsfMRI) in five large-scale cognitive brain networks.

Combination of serum microRNAs and ultrasound profile as predictive biomarkers of diagnosis and prognosis for papillary thyroid microcarcinoma.

Circulating microRNAs (miRNAs) are promising diagnostic markers in various types of cancers, including papillary thyroid carcinoma (PTC). However, there is sparse information reported with regards to miRNA expression in papillary thyroid microcarcinoma (PTMC) or concerning the role of a combination of miRNAs and ultrasound (US) in the diagnosis of PTMC before surgery. Therefore, we designed a study that aimed to evaluate miRNA expression levels and their potential associations with US findings and determine whether miRNAs could be used as diagnostic and prognostic biomarkers of PTMC.

Surface modification of PGP for a neutrophil-nanoparticle co-vehicle to enhance the anti-depressant effect of baicalein.

Exploiting cells as vehicles combined with nanoparticles combined with therapy has attracted increasing attention in the world recently. Red blood cells, leukocytes and stem cells have been used for tumor immunotherapy, tissue regeneration and inflammatory disorders, and it is known that neutrophils can accumulate in brain lesions in many brain diseases including depression. -Acetyl Pro-Gly-Pro (PGP) peptide shows high specific binding affinity to neutrophils through the CXCR2 receptor.

Effects of combined radiosurgery and temozolomide therapy on epidermal growth factor receptor and variant III in glioblastoma multiforme.

Glioblastoma multiforme (GBM) is a highly malignant and notably aggressive primary tumour. Variant III of the epidermal growth factor receptor (EGFRvIII) is one of the most common types of variants in GBM, and serves an important role in tumour invasion, proliferation and treatment resistance. In the present study, statistical analyses were performed on data from 57 patients with GBM, and polymerase chain reaction detection was conducted on the tumour tissues from 32 of these patients.

Dynamic monitoring of circulating microRNAs as a predictive biomarker for the diagnosis and recurrence of papillary thyroid carcinoma.

Circulating microRNAs (miRNAs/miRs) are considered to be potential biomarkers for numerous types of cancer. However, previous investigations into the expression of miRNAs in the serum of patients with papillary thyroid carcinoma (PTC) to predict diagnosis, prognosis and recurrence have reported conflicting results, and the role of miRNAs remains unclear. The present study dynamically assessed the circulating miRNA profile in patients with PTC and determined whether miRNAs in the serum could be used as biomarkers for the diagnosis, prognosis and recurrence of PTC.

NPTX2 and cognitive dysfunction in Alzheimer's Disease.

Memory loss in Alzheimer's disease (AD) is attributed to pervasive weakening and loss of synapses. Here, we present findings supporting a special role for excitatory synapses connecting pyramidal neurons of the hippocampus and cortex with fast-spiking parvalbumin (PV) interneurons that control network excitability and rhythmicity. Excitatory synapses on PV interneurons are dependent on the AMPA receptor subunit GluA4, which is regulated by presynaptic expression of the synaptogenic immediate early gene NPTX2 by pyramidal neurons.

A LC-MS/MS method for the determination of stachyose in rat plasma and its application to a pharmacokinetic study.

A sensitive, simple and rapid analytical method based on a liquid chromatography-tandem mass spetrometry (LC-MS/MS) has been established and validated for the determination of stachyose in rat plasma. Plasma samples were prepared by protein precipitation with acetonitrile. Separation of stachyose and nystose (internal standard, IS) was achieved using acetonitrile-water (55:45, v/v) as the mobile phase at a flow rate of 1 ml/min for 6 min on an Asahipak NH2P-50 4E column with an Asahipak NH2P-50G 4A guard column.

Definition of a Bidirectional Activity-Dependent Pathway Involving BDNF and Narp.

One of the cardinal features of neural development and adult plasticity is the contribution of activity-dependent signaling pathways. However, the interrelationships between different activity-dependent genes are not well understood. The immediate early gene neuronal-activity-regulated pentraxin (NPTX2 or Narp) encodes a protein that has been associated with excitatory synaptogenesis, AMPA receptor aggregation, and the onset of critical periods.

Increased cardiac distribution of mono-PEGylated Radix Ophiopogonis polysaccharide in both myocardial infarction and ischemia/reperfusion rats.

Although PEGylation plays an important role in drug delivery, knowledge about the distribution behavior of PEGylated drugs in ischemic myocardia is rather limited compared to nanoparticles. This work therefore aims to characterize the targeting behavior of the anti-myocardial ischemic mono-PEGylated conjugates of Radix Ophiopogonis polysaccharide (ROP) in two clinically relevant animal models, ie, the myocardial infarction (MI) model and the ischemia/reperfusion (IR) model. To determine the effect of the molecular size of conjugates, two representative conjugates (20- and 40-kDa polyethylene glycol mono-modified ROPs), with hydrodynamic size being approximately and somewhat beyond 10 nm, respectively, were studied in parallel at three time points postdose after a method for determining them quantitatively in biosamples was established.

[Application of factor analysis to evaluate deformation behaviors of frequently-used tablet excipients].

The present work is to investigate the correlation between physical properties and deformation behaviors of tablet excipients, and rank them according to their plastic performances during compaction. The excipients selected were compacted using Korsch XP1 after measuring their physical properties where the compression parameters for evaluating deformation behaviors were Heckle equation, compression work and elastic stretch in die. The correlations between compaction descriptors and physical parameters were analyzed by canonical correlation analysis, and factor analysis was simultaneously employed to synthetically assess deformation behaviors for all our samples.
