Oral probiotic extracellular vesicle therapy mitigates Influenza A Virus infection via blunting IL-17 signaling.

The influenza A virus (IAV) damages intestinal mucosal tissues beyond the respiratory tract. Probiotics play a crucial role in maintaining the balance and stability of the intestinal microecosystem. Extracellular vesicles (EVs) derived from probiotics have emerged as potential mediators of host immune response and anti-inflammatory effect.

Active cytomegalovirus infection in mechanically ventilated patients with sepsis.

Background: Active cytomegalovirus (CMV) infection is associated with poor prognosis in septic patients with critical illness. Patients of septic category are highly likely to benefit from prophylactic antiviral therapy. Nevertheless, the clinical characteristics for CMV reactivation are lacking among septic patients requiring mechanical ventilation.

The reduced interaction between SufS and SufU in Mycoplasma penetrans results in diminished sulfotransferase activity.

Mycoplasma Penetrans (Mpe) is an AIDS-related mycoplasma that is also closely related to respiratory diseases. Proteins involved in the first phase of Fe-S cluster biosynthesis in the SUF-like pathway are essential in Gram-positive bacteria because there is no redundant Fe-S cluster biosynthetic pathway in these proteins. In this study, we characterized two essential proteins: cysteine desulphurase (MpeSufS) and sulfurtransferase (MpeSufU) in Mpe, and resolved their crystal structures.

Insight into the mystery of Pheretima smells worse exposed to water: Identification, type, and volatility of stenchy odor.

Pheretima is a popular healthy food, but Pheretima and related foods have specific stenchy odor, especially after decocting or warm soaking, the odor is intense, resulting in nausea and vomiting. This indicates that the release of stenchy odor components is intensified when Pheretima was exposed to hot water. It is urgent to study the composition and release pattern of the stenchy odor components of Pheretima.

Synthesis, structure, spectra, cytotoxicity and photo induced NO release of four isomeric nitrosylruthenium complexes.

Four isomeric nitrosyl ruthenium complexes [RuCl(2mqn)(Val)(NO)] (1-4) were prepared (2mqn, 2-methyl-8-hydroxyquinoline; Val, l-valine) and characterized by H NMR, C NMR, absorption spectrum, electrospray ionization mass spectrometry, and X-ray crystal diffraction. Time-resolved FT-IR and fluorescence spectroscopy were used to monitor photo-induced NO release in solution, while NO released in living cells was imaged using a selective fluorescent probe. The isomeric complexes showed different levels of cytotoxicity against HeLa cells, and slightly photo-enhanced anti-proliferative activity was observed.

Zinc(ii)-mediated stereoselective construction of 1,2- 2-azido-2-deoxy glycosidic linkage: assembly of K48 capsular pentasaccharide derivative.

The capsular polysaccharide (CPS) is a major virulence factor of the pathogenic and a promising target for vaccine development. However, the synthesis of the 1,2--2-amino-2-deoxyglycoside core of CPS remains challenging to date. Here we develop a highly α-selective ZnI-mediated 1,2- 2-azido-2-deoxy chemical glycosylation strategy using 2-azido-2-deoxy glucosyl donors equipped with various 4,6--tethered groups.

Intelligent and biocompatible cellulose aerogels featured with high-elastic and fast-hemostatic for epistaxis and wound healing.

Nasal tamponade is a commonly employed and highly effective treatment method for preventing nasal bleeding. However, the current nasal packing hemostatic materials exhibit some limitations, such as low hemostatic efficiency, the potential for causing secondary injury when removed from the nasal cavity, limited intelligence in their design, and an inability to promote the healing of nasal mucosa wounds. Herein, we report the fabrication of a smart cellulose aerogel through the covalent cross-linking of carboxymethyl cellulose (CMC) macromolecules, while incorporating one-dimensional cellulose nanofibers (CNF) and two-dimensional MXene as reinforcing network scaffolds and conductive fillers.

A new diagnostic technique for identifying Angiostrongylus spp. larvae in intermediate snail species by examining the buccal cavity.

Background: Angiostrongyliasis is a zoonotic parasitic disease caused by the rat lungworm Angiostrongylus cantonensis. The intermediate hosts of A. cantonensis are gastropods, and snail species such as Pomacea canaliculata play a key role in the transmission of human angiostrongyliasis.

Effect of applying carbodiimide combined with a two-step self-etch adhesive durability.

Background: This study investigated the effect of carbodiimide (EDC) combined with Clearfil SE self-etch adhesive on the shear bond strength (SBS), crosslinking degree, denaturation temperature, and enzyme activity of dentin in vitro.

Materials And Methods: Collected human sound third molars were randomly divided into different groups with or without EDC treatment (0.01-1 M).

Research on the mechanism of consumer participation in value co-creation by innovative enterprises: An evolutionary game analysis framework.

The profound changes brought about by informatization and digitalization have given rise to the user-centered innovation concept, and value co-creation by enterprises has become an inevitable trend. It has become a pressing issue for scholars to analyze the mechanism of consumer participation in the value co-creation of innovative enterprises. In this paper, by establishing an evolutionary game model between consumers and innovative enterprises, we analyze in depth the mechanism of consumer participation in the value co-creation of innovative enterprises.

Chlorination Design for Highly Stable Electrolyte toward High Mass Loading and Long Cycle Life Sodium-Based Dual-Ion Battery.

Sodium-based dual ion batteries (SDIBs) have garnered significant attention as novel energy storage devices offering the advantages of high-voltage and low-cost. Nonetheless, conventional electrolytes exhibit low resistance to oxidation and poor compatibility with electrode materials, resulting in rapid battery failure. In this study, for the first time, a chlorination design of electrolytes for SDIB, is proposed.

Prevalence of sarcopenic obesity in the older non-hospitalized population: a systematic review and meta-analysis.

Background: Sarcopenic obesity emerges as a risk factor for adverse clinical outcomes in non-hospitalized older adults, including physical disabilities, metabolic diseases, and even mortality. In this systematic review and meta-analysis, we investigated the overall SO prevalence in non-hospitalized adults aged ≥ 65 years and assessed the sociodemographic, clinicobiological, and lifestyle factors related to SO.

Methods: We searched the PubMed, Embase, Cochrane Library, and Web of Science databases for studies reporting the prevalence of SO from database inception to October 2023.

B(CF)-Catalyzed Stereoselective 1,2- Arabinofuranosylation with a Conformationally Constrained Donor.

Compared with stereoselective glycosylation methods mainly addressed on the preparation of pyranose glycosides, the furanosylation has been more limited, especially for the 1,2- arabinofuranosylation. Herein, we report a novel stereoselective 1,2--arabinofuranosylation strategy using a conformationally restricted 3,5--xylylene-protected arabinofuranosyl donor on activation with B(CF) for desired targets in moderate to excellent yields and β-stereoselectivity. The effectiveness of the 1,2--arabinofuranosylation strategy was demonstrated successfully with various acceptors, including carbohydrate alcohols.

Increased neutrophil-derived IL-17A identified in generalized pustular psoriasis.

Generalized pustular psoriasis (GPP) is considered to be a distinct clinical entity from psoriasis vulgaris (PV), with different clinical and histological manifestations. The pathogenesis of GPP has not been thoroughly elucidated, especially in those patients lacking interleukin (IL)36RN. In present study, we performed RNA sequence analysis on skin lesions from 10 GPP patients (4 with and 6 without IL36RN mutation) and 10 PV patients without IL36RN mutation.
