Olfactory ensheathing cells as candidate cells for chronic pain treatment.

Chronic pain is often accompanied by tissue damage and pain hypersensitivity. It easily relapses and is challenging to cure, which seriously affects the patients' quality of life and is an urgent problem to be solved. Current treatment methods primarily rely on morphine drugs, which do not address the underlying nerve injury and may cause adverse reactions.

Electrochemical Synthesis and Electrocatalytic Oxygen-Evolution Performance of Two-Dimensional NiCo-BPDC Materials.

Metal-organic frameworks (MOFs) have been widely studied as electrocatalysts, and the research strategy to improve their electrocatalytic oxygen evolution reaction (OER) performance is to modify their structure. In this paper, two-dimensional bimetallic MOFs were constructed to improve electrocatalytic OER performance. Using a mild electrochemical method with Ni and Co as metal sources and 4, 4 '-biphenyl dicarboxylic acid (HBPDC) as ligand, two-dimensional NiCo-BPDC was synthesized and then deposited on a carbon cloth electrode.

Prevalence and Etiological Characteristics of Norovirus Infection in China: A Systematic Review and Meta-Analysis.

Norovirus is a common cause of sporadic cases and outbreaks of gastroenteritis worldwide, although its prevalence and the dominant genotypes responsible for gastroenteritis outbreaks remain obscure. A systematic review was conducted on norovirus infection in China between January 2009 and March 2021. A meta-analysis and beta-binomial regression model were used to explore the epidemiological and clinical characteristics of norovirus infection and the potential factors contributing to the attack rate of the norovirus outbreaks, respectively.

[Pharmacokinetic interaction of Jiaotai Pills and Fluoxetine in rats with CUMS-induced depression].

A high-performance liquid chromatography-tandem mass spectrometry(LC-MS/MS) was developed for simultaneously determining the components(magnoflorine, jatrorrhizine, berberrubine, coptisine, berberine) of Jiaotai Pills and Fluoxetine in plasma of rats with chronic unpredictable mild stress(CUMS)-induced depression to investigate the pharmacokinetic herb-drug interaction of Jiaotai Pills and Fluoxetine in the rats. The six components showed good linear relationship within the corresponding concentration ranges, and the method showed high specificity, accuracy, precision, and stability. Their pharmacokinetic parameters were calculated by DAS 3.

Study on the graft modification mechanism of macroporous silica gel surface based on silane coupling agent vinyl triethoxysilane.

In this research, the graft modification mechanism of coupling agent vinyl triethoxysilane (KH-151) to macroporous silica gel was studied using a combination of multiple methods. SEM, FTIR, RAMAN, NMR and XPS were used to characterize the silica gel before and after grafting, determining the mechanism of the grafting reaction of the silane coupling agent. On this basis, the grafting rate of the coupling agent was accurately calculated by TGA weight loss.

[Effects of Jiaotai Pills on CUMS-induced depression model in mice based on changes of SIRT1 expression in hippocampus].

The present study investigated the effects and mechanisms of Jiaotai Pills on depressed mice induced by chronic unpredictable mild stress(CUMS). The CUMS-induced depression model mice were established and the depression behaviors of mice were evaluated by sucrose preference test, open field test, tail suspension test, and forced swimming test. Molecular docking was employed to simulate the interaction of six main active ingredients in Jiaotai Pills with SIRT1.

Measuring Mutator Enzyme Activity Using an E. coli-Based Colony Formation Assay.

Mutator enzymes alter the nucleotide sequences of DNA or RNA molecules; immune systems utilize them to destroy the integrity of pathogen genomes and to optimize immune mediators of the host. Their dysregulation has been linked to tumorigenesis in various tissues. Defining and comparing the activities of such mutator enzymes requires a robust versatile assay that is independent of their biological context as in vivo mutation rates are typically low.

Rapid detection of human heart-type fatty acid-binding protein in human plasma and blood using a colloidal gold-based lateral flow immunoassay.

The incidence of acute myocardial infarction (AMI) is currently increasing. Early detection is important for the treatment and prognosis of patients with AMI. Heart-type fatty acid-binding protein (H-FABP) may be used as an early marker of AMI due to its high sensitivity, specificity and prognostic value.

Investigation of Efficacy Enhancing and Toxicity Reducing Mechanism of Combination of Aconiti Lateralis Radix Praeparata and Paeoniae Radix Alba in Adjuvant-Induced Arthritis Rats by Metabolomics.

Combination of Aconiti Lateralis Radix Praeparata (FZ) and Paeoniae Radix Alba (BS) shows a significant effect in rheumatoid arthritis (RA). This study aimed to investigate the efficacy enhancing and toxicity reducing mechanism of combination of them in adjuvant-induced arthritis (AIA) rats by metabolomics. Rats were randomly divided into seven groups, including A (healthy control), B (model control), C1 (therapy group), C2 (efficacy enhancing group), D1 (toxicity group), and D2 (toxicity reducing group), and dexamethasone group was used as positive control.

Analysis of Immune Responses in Mice Orally Immunized with Recombinant pMG36e-SP-TSOL18/ and pMG36e-TSOL18/ Vaccines of .

Cysticercosis is a cosmopolitan zoonotic parasitic disease infected by larval of (). Several drugs for the treatment of cysticercosis, such as praziquantel, albendazole, and mebendazole, have certain toxicity and side effects. Considering that there is no vaccine available, we studied a new vaccine for cysticercosis in this study.

AID/APOBEC-like cytidine deaminases are ancient innate immune mediators in invertebrates.

In the course of both innate and adaptive immunity, cytidine deaminases within the activation induced cytidine deaminase (AID)/apolipoprotein B editing complex (APOBEC) family modulate immune responses by mutating specific nucleic acid sequences of hosts and pathogens. The evolutionary emergence of these mediators, however, seems to coincide precisely with the emergence of adaptive immunity in vertebrates. Here, we show a family of genes in species within two divergent invertebrate phyla-the echinoderm Strongylocentrotus purpuratus and the brachiopod Lingula anatina-that encode proteins with similarities in amino acid sequence and enzymatic activities to the vertebrate AID/APOBECs.

[Research progress on metabolism and pharmacological activities of several iridoid glycosides].

As a large category of natural products widely present in traditional Chinese medicine, iridoid glycosides have multiple pharmacological activities. Recent researches suggest that iridoid glycosides mainly exist in the forms of original form, aglycone and a series of their Ⅰ and Ⅱ metabolites under the biotransformation effect, and their metabolites have been proved to have multiple pharmacological activities. The research progress on metabolism and metabolite activities of several iridoid glycosides would be reviewed in this article, to provide a theoretical basis for the further development and utilization of iridoid compounds and their metabolites.

Internal Carotid Artery and its Relationship with Structures in Sellar Region: Anatomic Study and Clinical Applications.

Background: Complications of the internal carotid artery (ICA) in surgery are rare but severe. This study aimed to locate the ICA with 5 stationary bony structures in the sellar region: the anterior clinoid process, the tuberculum sellae, the bottom of the hypophyseal fossa, the posterior edge of the hypophyseal fossa, and the postclinoid process and to do measurements to determine their anatomic relationship with the ICA.

Methods: After multiple planar reconstructions on computer tomographic angiography images of 120 ICA in 60 individuals, we defined the 5 bony structures as 5 origins in the horizontal, sagittal, and vertical planes with the 3D coordinate system and got the cross-sections of bilateral ICA on the coronal plane passing through each origin.
