Background: Chronic pain has become an increasingly prevalent issue in primary care. Current management in modern medicine for chronic pain often remains unsatisfactory. Chinese herbal medicine has gained growing recognition as a complementary approach.

Bioprinting technology plays a crucial role for constructing tissue substitutes. However, the mismatched scaffold shapes and the poor treatment timeliness limit its clinical translational application. In situ printing technology that prints bioregenerants directly inside patient's body can meet the needs of specific tissue repair.

Two Gram-stain-negative, facultatively anaerobic, motile, and rod-shaped marine bacteria, designated strains ZSDZ35 and ZSDZ42, were isolated from surface seawater of Qingdao offshore. Phylogenetic analysis of the 16S rRNA genes and whole genome data placed ZSDZ35 and ZSDZ42 within the genus Enterovibrio. Strain ZSDZ35 was most closely related to Enterovibrio nigricans DSM 22720 with 97.

Deep-sea hydrothermal vents have been extensively explored around the globe in the past decades, and the diversity of microbial communities and their ecological functions related to hydrothermal vents have become hotspots in the study of microbial biogeochemistry. However, knowledge of dominant microbial communities and their unique metabolic characteristics adapting to hydrothermal vents is still limited. In our study, the sediment sample near the Tangyin hydrothermal vent in the southern part of the Okinawa Trough was collected, and the most abundant phyla are Proteobacteria and Desulfobacterota based on the 16S rRNA genes and metagenome sequencing.

Unlabelled: Hadal trenches are characterized by enhanced and infrequent high-rate episodic sedimentation events that likely introduce not only labile organic carbon and key nutrients but also new microbes that significantly alter the subseafloor microbiosphere. Currently, the role of high-rate episodic sedimentation in controlling the composition of the hadal subseafloor microbiosphere is unknown. Here, analyses of carbon isotope composition in a ~ 750 cm long sediment core from the Challenger Deep revealed noncontinuous deposition, with anomalous C ages likely caused by seismically driven mass transport and the funneling effect of trench geomorphology.

Members of the family (vibrios) are widely distributed in estuarine, offshore, and marginal seas and perform an important ecological role in the marine organic carbon cycle. Nevertheless, there is little knowledge about whether vibrios play ecological roles in the oligotrophic pelagic area, which occupies a larger water volume. In this study, we investigated the abundance, diversity, and composition of free-living and particle-associated vibrios and their relationships with environmental factors along the water depth in the eastern tropical Indian Ocean (ETIO).

Dimethylsulfoniopropionate (DMSP) and related organic sulfur compounds play key roles in global sulfur cycling. Bacteria have been found to be important DMSP producers in seawater and surface sediments of the aphotic Mariana Trench (MT). However, detailed bacterial DMSP cycling in the Mariana Trench subseafloor remains largely unknown.

A Gram-straining-negative, facultatively anaerobic, motile by means of a polar flagellum and rod-shaped marine bacterium, designated S4M6, was isolated from surface seawater collected in Dongshan Bay (Fujian, PR China). Phylogenetic analysis based on 16S rRNA genes, phylogenomic analysis of single-copy gene families and whole genome data indicated that S4M6 represented a member of the genus . The closest phylogenetic relatives of S4M6 were CGMCC 1.

Background: Rising incidence of inflammation-related diseases is an increasing concern nowadays. However, while menthol is a wildly-used and efficacious complementary medicine, its pharmacological mechanism still remains uncertain. Superimposed upon that, the aim of this review is to summarize the contemporary evidence of menthol's anti-inflammatory activity.

Article Synopsis
  • Alginate is a vital polysaccharide in the ocean that assists marine microorganisms, with species like Vibrio pelagius WXL662 being particularly effective at degrading it through multiple alginate lyases identified in its genome.* -
  • The study identified three alginate utilization loci (AUL) in WXL662, which contain critical genes that are highly expressed when alginate is the sole carbon source, demonstrating the strain's adaptability to varying marine environments.* -
  • Findings reveal that unlike previous beliefs of scattered alginate-degrading systems, most vibrios have a concentrated AUL, suggesting that Vibrio pelagius WXL662 can serve as a valuable model for understanding the ecological role of alginate degradation in marine ecosystems.*

Cold shock proteins (Csps) are small and highly conserved proteins that have target RNA- and DNA-binding activities. Csps play roles in different cellular processes and show functional redundancy. Ralstonia solanacearum, the agent of bacterial wilt, has 4 or 5 Csps based on genome analysis.
