Multi-omics analysis revealed biomarkers for coronary atherosclerosis: Occurrence and development.

Background: Coronary atherosclerosis (CA) is a leading cause of cardiovascular diseases with the high morbidity and mortality; however, the current diagnostic methods, primarily based on symptoms, signs, lab examination and imaging, are often inadequate for detecting subclinical or early-stage CA, costly, and inaccessible in many cases. The objective of this study was to discover sensitive and specific biomarkers for the diagnosis of CA severity.

Medium-chain triglyceride attenuates obesity by activating brown adipose tissue via upregulating the AMPK signaling pathway.

Medium-chain triacylglycerol (MCT) is a healthy lipid mainly composed of medium-chain fatty acids (MCFA), which has been proven to have physiological activities in improving metabolic disorders, reducing blood cholesterol, and controlling weight. Brown adipose tissue (BAT) has been regarded as a potential organ to fight obesity due to the function of thermogenesis and energy dissipation. Previous reports found that a diet rich in MCT contributed to the activation of BAT.

Spexin and its receptors in the yellowtail kingfish (Seriola lalandi): identification, expression profiles and reproductive function.

Spexin (SPX1) is a neuropeptide of 14 amino acids (aa), originally identified by bioinformatics, which has been implicated in various physiological functions in vertebrates via galanin receptors 2 and 3 (GALR2/3). To clarify the biological role of SPX1 in the control of reproduction in yellowtail kingfish, which is regarded as a promising species for offshore aquaculture worldwide, cDNA sequences of spx1 and six potential receptors were identified in the current study. The open reading frame of yellowtail kingfish spx1 was 363 nucleotides in size that encoded a 120-aa preprohormone, and its mature peptide was highly conserved among other species.

Leptins regulate the migration, proliferation, apoptosis, and synthesis of sexual steroid in tongue sole (Cynoglossus semilaevis) ovarian cells.

Leptin is an important hormone in mammals, which plays a key role in regulating reproduction and energy metabolism. However, there are few studies on the function of leptin in reproductive regulation in fish, especially on tongue sole (Cynoglossus semilaevis). Thus, in this study, we firstly exploited the basic function of tongue sole leptins, the migration and growth rate of ovarian cells were reduced after knocking down lepA and lepB in ovarian cells, while increasing the apoptosis rate.

A diamond-bearing core-mantle boundary on Mercury.

Abundant carbon was identified on Mercury by MESSENGER, which is interpreted as the remnant of a primordial graphite flotation crust, suggesting that the magma ocean and core were saturated in carbon. We re-evaluate carbon speciation in Mercury's interior in light of the high pressure-temperature experiments, thermodynamic models and the most recent geophysical models of the internal structure of the planet. Although a sulfur-free melt would have been in the stability field of graphite, sulfur dissolution in the melt under the unique reduced conditions depressed the sulfur-rich liquidus to temperatures spanning the graphite-diamond transition.
