Synthesis of Ru-W/CeZrO catalyst with superior NH-SCO performance: Synergy between Ru and W species.

Ammonia selective catalytic oxidation (NH-SCO) is an effective method for NH removal. However, it is still a great challenge to develop catalysts with a wide operating temperature window, high catalytic activity and N selectivity, particularly for the removal of high-concentration NH from NH-fueled engine exhaust gas. Herein, a small amount of Ru (0.

Dynamics alteration of the gut microbiota and faecal metabolomes in very low or extremely low birth weight infants: a Chinese single-center, prospective cohort study.

Objective: The aim of this study is to comprehensively investigate the temporal dynamics of faecal gut microbiota and metabonomics in early postnatal with a focus on very low or extremely low birth weight (VLBW/ELBW) infants.

Methods: We collected faecal samples from 157 VLBW/ELBW infants at three time points: days 1, 14, and 28 in a prospective cohort study. The faecal microbial diversity, abundance, composition, and metabolomic analyses were determined using 16S rRNA sequencing and liquid chromatography tandem mass spectrometry (LC-MS/MS).

Development and Validation of an In-Hospital Mortality Prediction Model for Patients with Acute Exacerbation of Chronic Obstructive Pulmonary Disease.

Purpose: Patients with chronic obstructive pulmonary disease (COPD) often face unknown risks during acute exacerbation of the disease (AECOPD), which could potentially result in mortality. This study aimed to develop and validate a nomogram model for predicting the risk of in-hospital mortality in AECOPD patients.

Patients And Methods: Clinical data of patients hospitalized at The Second People's Hospital of Wuhu City for AECOPD between January 2013 and December 2022 were retrospectively collected.

Pt/AlO@Ce/ZrO-S bifunctional catalysts prepared by mechanically milling for selective catalytic oxidation of high-concentration ammonia.

The selective catalytic oxidation (SCO) is an effective method for removing slipped high-concentration ammonia from NH-fueled engine exhaust gas. Herein a novel bifunctional catalyst was synthesized by mechanically mixing sulfated Ce/ZrO (Ce/ZrO-S) with a small fraction of Pt/AlO (Pt 0.1 wt.

Assessing the sustainability and competitiveness of tourism economies in China's Chengdu-Chongqing metropolitan area.

As the competition of tourism industry becomes increasingly white-hot, the sustainability and competitiveness of tourism economies inside a zone gradually gets people's attentions. Based on data of 16 cities from 2010 to 2019, this paper aims to investigate the sustainability and competitiveness of tourism economies in the Chengdu-Chongqing metropolitan area, by constructing a niche evaluation index and four niche models (niche ecostate-ecorole model, niche expansion model, niche breadth model, and niche overlap degree model). The results show that (1) during the sample period, the niche values of tourism competitiveness in most cities of the Chengdu-Chongqing metropolitan area have shown a sustained increasing trend, indicating that the status of these cities in resources, market, environment, social economy, and other dimensions is rising steadily, and their competitive advantages are gradually increasing; (2) the niche values of tourism competitiveness in the core cities of Chengdu-Chongqing metropolitan area (Chengdu and Chongqing) remain stable, while the niche values of tourism competitiveness in the remaining cities vary greatly; the comprehensive niche values of tourism industry competitiveness of the cities in the central area are significantly lower than those of the cities in the peripheral area; (3) the niche overlap of tourism competitiveness in the Chengdu-Chongqing metropolitan area is relatedly high, indicating that the homogenization of tourism in these cities is more serious.

Geographical distribution of hyperuricemia in mainland China: a comprehensive systematic review and meta-analysis.

Background: Fructose plays an important role in the complex metabolism of uric acid in the human body. However, high blood uric acid concentration, known as hyperuricemia, is the main risk factor for development of gout. Therefore, we conducted an updated meta-analysis on the prevalence and geographical distribution of hyperuricemia among the general population in mainland China using systematic literature search.

Increased stressful impact among general population in mainland China amid the COVID-19 pandemic: A nationwide cross-sectional study conducted after Wuhan city's travel ban was lifted.

Objectives: Our study aimed to determine the impact of the COVID-19 pandemic on psychological responses and lifestyle changes among the general population in mainland China following the re-opening of the Wuhan city.

Methods: A cross-sectional survey was conducted in April 2020. Participants of Chinese nationality aged ⩾ 18 years were asked to complete a modified validated Chinese version of a questionnaire regarding the impact of event scale (IES), family and social support, mental health-related lifestyle changes, and indicators of negative mental health impacts.

Low fermentable oligosaccharides, disaccharides, monosaccharides, and polypols diet and irritable bowel syndrome in Asia.

Functional bowel disorders, including irritable bowel syndrome (IBS), are a chronic condition that can significantly reduce patients' quality of life. Therefore, this paper will review the roles of a low fermentable oligosaccharides, disaccharides, monosaccharides, and polypols (FODMAP) diet in treating IBS, particularly in an Asian setting. About 20% of the general population is diagnosed with IBS.

Exposure to Ambient Particles Alters the Evolution of Macrophage Phenotype and Amplifies the Inducible Release of Eotaxin-1 in Allergen-Sensitized Mice.

So far, epidemiological data have revealed that the elevation of fine ambient particulate matter (aerodynamic diameter ≤2.5 m; PM2.5) is closely associated with an exacerbation of asthma while the underlying mechanism is poorly understood.

Oligomeric proanthocyanidins attenuate airway inflammation in asthma by inhibiting dendritic cells maturation.

To date, although a promising anti-inflammatory activity of oligomeric proanthocyanidins (OPCs) has been observed in asthma, the mechanism responsible for these immunomodulatory properties remains obscure. Dendritic cells (DCs) that reside in the airway have been widely perceived as an important contributor to asthma. Our study was to demonstrate OPCs' effects on maturation and immunoregulation of pulmonary CD11c dendritic cells (DCs).

Diosmetin prevents TGF-β1-induced epithelial-mesenchymal transition via ROS/MAPK signaling pathways.

Aims: Epithelial-mesenchymal transition (EMT) plays a critical role in airway repair and remodeling in many respiratory diseases such as asthma and pulmonary fibrosis. The flavone aglycone, diosmetin, possesses anti-remodeling activity in a murine model of chronic asthma, but little is known about its effects on EMT. Herein, we investigated whether diosmetin inhibits transforming growth factor-β1 (TGF-β1)-induced EMT with underlying mechanisms in human bronchial epithelial (HBE) cells.
