We investigated the potential probiotic properties of KGC1601 isolated from . Ginseng cultivated in an experimental field of the Korea Ginseng Research Institute was fermented, followed by single colony selection from MRS agar. We performed 16s-rRNA sequencing and whole-genome analysis to identify and evaluate the biosafety parameters of this strain, respectively. We confirmed this strain was susceptible to six antibiotics, as proposed by the European Food Safety Authority, did not produce biogenic amines, and did not exhibit any hemolytic activity. Acid resistance and bile salt tolerance, which are essential properties of a probiotic agent, were investigated. Notably, distinguishing properties of this strain were that it exhibited excellent bile salt tolerance and anti-inflammatory effects. The excellent bile salt tolerance was confirmed by scanning electron microscopy. Through qRT-PCR and ELISA studies, it was revealed that KGC1601 pre-treatment up-regulates anti-inflammatory cytokines and down-regulates pro-inflammatory cytokines in RAW 264.7 cells. Consequently, we suggested that KGC1601 can be safely used as a potential anti-inflammatory functional probiotic agent.

Alterations in bile acid profile and pathways contribute to hepatic inflammation in cancer cachexia, a syndrome worsening the prognosis of cancer patients. As the gut microbiota impinges on host metabolism through bile acids, the current study aimed to explore the functional contribution of gut microbial dysbiosis to bile acid dysmetabolism and associated disorders in cancer cachexia. Using three mouse models of cancer cachexia (the C26, MC38 and HCT116 models), we evidenced a reduction in the hepatic levels of several secondary bile acids, mainly taurodeoxycholic (TDCA).

Background And Objectives: Based on the Adverse Event Reporting System (FAERS) data from the US FDA, this study mined the adverse drug reactions of obeticholic acid (OCA) in the real world and provided reference for clinical safe drug use.
Methods: Adverse event reports for OCA from the second quarter of 2016 to the third quarter of 2023 were extracted. The analysis for adverse reaction signal detection was conducted using reporting odds ratio, proportional reporting ratio, Bayesian confidence propagation neural network, and multi-item gamma Poisson shrinker methods.

Deoxycholic acid (DCA) injection is applied in treating moderate to severe submental bulge or facial fullness caused by excessive submental fat accumulation. Using ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) technology, which was swiftly, precisely, and reliably confirmed, DCA was determined in human plasma with low quantification limits of 56 ng/mL. We selected six healthy individual blank human plasma with low concentrations of endogenous DCA and mixed them to prepare standard curve samples.

Multiple sclerosis (MS) is a devastating autoimmune disease that leads to the destruction of the myelin sheath in the human central nervous system (CNS). Infection by viruses and bacteria has been found to be strongly associated with the onset of MS or its severity. We postulated that the immune system's attack on the myelin sheath could be triggered by viruses and bacteria antigens that resemble myelin sheath components.
