Abstract Commensal Bacteroides fragilis possesses immune-regulatory characteristics. Consequently, it has been proposed as a potential novel probiotic because of its therapeutic effects on immune imbalance, mental disorders and inflammatory diseases. Macrophages play central role in the response, developing either classical-M1 or an alternative-M2 phenotype after stimulation with various signals. The interactions between macrophages B. , however, remain to be defined. Here, new isolate...
Antibiotic-associated diarrhea (AAD) is iatrogenic characterized by disruption of the gut microbiota. Probiotics are routinely used to treat AAD in clinical practice; however, effectiveness and mechanisms which probiotics alleviate symptoms remain poorly understood. We previously isolated a non-toxic Bacteroides fragilis (B. fragilis) strain ZY-312, has been verified be beneficial certain infection disorders. However, precise role this commensal bacterium unknown. In study, we successfully...
Absolute displacement signals of vibrating platforms/objects are often needed in vibration control, signal processing, and object tracking. Motivated by the practical requirement engineering applications, this study presents analysis design a novel bioinspired dynamics sensor system for absolute measurement. The is constructed using simple beams springs, which indicates possible way achieving nonlinear quasi-zero stiffness consequently creating broadband vibration-free point measurement...
Most bacteria in the human gut are difficult to culture, and culturomics has been designed overcome this issue. Culturomics makes it possible obtain living for further experiments, unlike metagenomics. However, is work-intensive, which prevents its wide application. In study, we performed a 30-day continuous enrichment blood culture bottles cultured bacterial isolates from pre-cultures removed at different time points. We compared isolated enriched with or without adding fresh medium after...
Bacteroides fragilis is an anaerobic, Gram-negative, commensal bacterium of the human gut. It plays important role in promoting maturation immune system, as well suppressing abnormal inflammation. Many recent studies have focused on relationship between B. and immunity, indicate that has many useful probiotic effects. As inhibition intestinal pathogens characteristic strains, this study examined whether could inhibit pathogenic bacteria. Results showed Vibrio parahaemolyticus was inhibited...
This paper proposes a bioinspired reference model based fuzzy adaptive tracking control for active suspension systems. A general nonlinear structure, which can present ideal quasi-zero stiffness vibration isolation, is adopted as model. Fuzzy logic systems are used to approximate unknown terms in Particularly, damping designed improve characteristics of the With beneficial and improved model, proposed controller effectively suppress with less actuator force much ride comfort, thus energy...
In this paper, the event-triggered robust filtering problem is investigated for a class of network-based state-dependent uncertain systems in sense finite-time boundedness, considering network transmission delay. By resorting to generalized performance index, H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">∞</sub> and L xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> - problems can be solved unified framework. An scheme also utilized sift...
Most mobile robots have very simple passive suspension based on conventional mass-spring-damper methods, which bring a trade-off between loading capacity and vibration isolation, or no at all with only hard contact wheels ground. This article presents tracked robot unique suspension, is constructed by using bio-inspired animal-limb-like structure, to guarantee both isolation performance. With the novel capacity, riding comfort obstacle negotiation capability of in various rough ground...
Although the role and mechanism of neutrophils in tumors have been widely studied, precise effects aryl hydrocarbon receptor nuclear translocator (ARNT) on remain unclear. In this study, we investigated roles ARNT function CD11b+Gr1+ colitis-associated colorectal cancer. Wild-type (WT), myeloid-specific deficient mice a cancer mouse model were used study. The level functions cells evaluated by flow cytometry confocal microscopy. We found that deficiency drives recruitment, neutrophil...
This study aimed to explore the relationship between changes in early degradation products of polysaccharide coatings (such as hyaluronic acid (HA), syndecan-1 (SDC-1), and heparan sulfate (HS)) development organ dysfunction sepsis patients. We conducted a retrospective analysis on 140 patients admitted from January 2021 June 2022, who formed group; 100 healthy individuals underwent health checks during same period were included control group. The found that expression levels HA, SDC-1, HS...

Abstract Background Culturomics can ascertain traces of microorganisms to be cultivated using different strategies and identified by matrix-assisted laser desorption/ionization–time-of-flight mass spectrometry or 16S rDNA sequencing. However, cater all requirements isolate as many species possible, multiple culture conditions must used, imposing a heavy workload. In addition, the fast-growing bacteria (e.g., Escherichia ) surpass slow-growing in occupying space up nutrients. Besides, some...
