The First Genome Survey of the Snail Inhabiting Deep-Sea Hydrothermal Vents.

The snail is an endemic species in deep-sea chemosynthetic ecosystems of the Northwest Pacific Ocean. To obtain more genetic information on this species and provide the basis for subsequent whole-genome map construction, a genome survey was performed on this snail from the hydrothermal vent of Okinawa Trough. The genomic size of was estimated to be 1.

Numerical Simulation of Physical Fields during Spark Plasma Sintering of Boron Carbide.

Spark plasma sintering is a new technology for preparing ceramic materials. In this article, a thermal-electric-mechanical coupled model is used to simulate the spark plasma sintering process of boron carbide. The solution of the thermal-electric part was based on the charge conservation equation and the energy conservation equation.

Identification and validation of potential hub genes in rheumatoid arthritis by bioinformatics analysis.

Objective: Rheumatoid arthritis (RA) is considered to be a chronic immune disease pathologically characterized by synovial inflammation and bone destruction. At present, the potential pathogenesis of RA is still unclear. Hub genes are recognized to play a pivotal role in the occurrence and progression of RA.

Effect of chrono-moxibustion and its influence on circadian rhythm for rheumatoid arthritis: A study protocol for a randomized controlled trial.

Background: Rheumatoid arthritis (RA) is a chronic disease which is characterized by a circadian variation of key clinical symptoms and findings, with prominent joint swelling, stiffness and pain occurring in the early morning and light clinical symptoms during the day. Chrono-moxibustion is carried out at different time, which could result in dissimilar therapeutic effects. However, its efficacy has seldom been systematically demonstrated and few studies have reported that Chrono-moxibustion may regulate the circadian rhythm of RA.

Full-length 16S rRNA amplicon sequencing reveals the variation of epibiotic microbiota associated with two shrimp species of Alvinocarididae: possibly co-determined by environmental heterogeneity and specific recognition of hosts.

Shrimps of the family Alvinocarididae, endemic species to deep sea chemosynthetic ecosystems, harbor epibiotic microbes on gills which probably play important roles in the survival of the shrimps. Among them, and occupy different ecological niches within the same hydrothermal vent in Okinawa Trough, and also exists in a methane seep of the South China Sea. In this study, full-length 16S rRNA sequences of the gill associated bacteria of two alvinocaridid species from different chemosynthetically ecological niches were first captured by single-molecule real-time sequencing.

Chrono-moxibustion adjusts circadian rhythm of CLOCK and BMAL1 in adjuvant-induced arthritic rats.

Objective: The clinical symptoms of rheumatoid arthritis (RA) have significant circadian rhythms, with morning stiffness and joint pain. Moxibustion is effective in the treatment of RA, while the underlying therapeutic mechanisms remain limited. Thus, we explored whether moxibustion could adjust the circadian rhythm of RA by modulating the core clock genes CLOCK and BMAL1 at the molecular level.

Microstructure and Mechanical Properties of TiN-TiB-hBN Composites Fabricated by Reactive Hot Pressing Using TiN-B Mixture.

In this study, TiN-TiB-hBN composite ceramics were prepared via reactive hot pressing using TiN and amorphous B powders as raw materials. Different sintering temperatures and composition ratios were studied. The results show that the 70 vol% TiN-17.
