The exploration of short-wave ultraviolet (SUV; λ < 280 nm) transparent phosphates with substantial birefringence is crucial for the advancement of SUV laser industry. Despite their SUV transparency and potential for constructing materials with large birefringence, open-framework (OF) phosphates have rarely been explored for their birefringent properties. Herein, through a systematic exploration in this field, a new ethylenediamine-based OF zincophosphate, Na(CHN)[Zn(PO)(HPO)] (NEZPO), has been developed.

Objective: At present, targeting molecular-pharmacological therapy is still difficult in neutrophilic asthma. The investigation aims to identify and validate mitochondrion-related gene signatures for diagnosis and specific targeting therapeutics in neutrophilic asthma.

Methods: Bronchial biopsy samples of neutrophilic asthma and healthy people were identified from the GSE143303 dataset and then matched with human mitochondrial gene data to obtain mitochondria-related differential genes (MitoDEGs).

Host immunity can influence the composition of the gut microbiota and consequently affect disease progression. Previously, we reported that a Mycobacterium vaccae vaccine could ameliorate allergic inflammation in asthmatic mice by regulating inflammatory immune processes. Here, we investigated the anti-inflammatory effects of M.

Severe acute respiratory syndrome coronavirus 2 infection is associated with strong infectiousness and has no effective therapy. We aimed to explore the efficacy and safety of nebulization in the treatment of Coronavirus Disease 2019 (COVID-19). In this randomized, double-blind, placebo-controlled clinical trial, we included 31 adult patients with moderate COVID-19 who were admitted to the Fourth People's Hospital of Nanning (Nanning, China) between January 22, 2020 and February 17, 2020.

Objective: In this study, we aimed to identify prognostic immune-related genes and establish a prognostic model for laryngeal cancer based on these genes.

Methods: Transcriptome profiles and clinical data of patients with laryngeal cancer were downloaded from The Cancer Genome Atlas database. Integrated bioinformatics analyses were performed to identify genes associated with prognosis.

The objective of this study was to investigate the effect of Mycobacterium vaccae on Jagged 1 and gamma delta T17 (γδT17) cells in asthmatic mice. An asthma mouse model was established through immunization with ovalbumin (OVA). Gamma-secretase inhibitor (DAPT) was used to block the Notch signaling pathway.

Background: The overexpression of TSLP and DNA methylation in asthma were both risk factors the relationship was not clear.

Objective: This study aimed to investigate the relationship between methylation status of TSLP promoter and mRNA/protein expression in asthmatic airway epithelial cells.

Methods: Human bronchial epithelial cells were cultured in vitro and divided into: Control group, treated with PBS, model group, sensitized with LPS (10 μg/mL) for 12 h (37 °C, 5% CO).

Background: nebulization imparted protective effect against allergic asthma in a mouse model. The TGF-β/Smad signal transduction pathway plays an important role in allergic bronchial asthma. However, the effect of nebulization on the TGF-β/Smad signal transduction pathway in mouse models of allergic asthma remains unclear.

Objectives: Bronchial asthma can be effectively controlled but not be cured, its etiology and pathogenesis are still unclear, and there are no effective preventive measures. The key characteristic of asthma is chronic airway inflammation, and recent research has found that airway neurogenic inflammation plays an important role in asthma. We previously found that nebulization protects against asthma.

Ozone is a strong oxidant in air pollution that exacerbates respiratory disorders and is a major risk factor for acute asthma exacerbation. Ozone can induce reactive oxygen species (ROS) and airway neutrophilic inflammation. In addition, γδT17 cells contribute to IL-17A production upon ozone challenge, resulting in neutrophilic inflammation.

Recently, Chen and Ma [A generalized shift-splitting preconditioner for saddle point problems, Applied Mathematics Letters, 43 (2015) 49-55] introduced a generalized shift-splitting preconditioner for saddle point problems with symmetric positive definite (1,1)-block. In this paper, I establish a parameterized shift-splitting preconditioner for solving the large sparse augmented systems of linear equations. Furthermore, the preconditioner is based on the parameterized shift-splitting of the saddle point matrix, resulting in an unconditional convergent fixed-point iteration, which has the intersection with the generalized shift-splitting preconditioner.

We aimed to explore the imbalance between the T helper 17 γδT cells (γδT17) and the regulatory γδT cells (γδTreg) in asthmatic mice. Male Balb/c mice were randomly divided into the normal control group and the asthmatic model group. The asthmatic model group mice were intraperitoneally injected with the mixture of ovalbumin (OVA)/Al(OH)3 and then activated by exposure of the animals to OVA atomization.

Recent studies suggest that imbalances in the ratios of CD4+ T helper cell subsets, T helper-17 (Th17) and regulatory T (Treg) cells play a crucial role in the pathogenesis of acute lung injury (ALI). However, studies of the imbalance of Th17/Treg in paraquat (PQ)-induced ALI have not been reported. Therefore, we investigated whether the ratio of Th17/Treg cells in a mouse model of PQ-induced ALI contributes to pathogenesis of ALI.
