Neotuberostemonine (NS) and tuberostemonine (TS), a pair of stereoisomers, are the active components contained in Stemona tuberosa, an antitussive herbal medicine in China. Two isomers have different pharmacological efficacies, which will be related with their in vivo disposition. However, the metabolic fates of NS and TS remain unknown. A method of high performance liquid chromatography/quadrupole time-of-flight mass spectrometry coupled with mass detect filter technique was established to investigate the metabolites in rat plasma, bile, urine, and feces after oral administration of the equal doses of NS and TS...

BACKGROUND: Feed costs are a major expense in the production of beef cattle. Individual variation in the efficiency of feed utilization may be evident through feed efficiency-related phenotypes such as those related to major energetic sinks. Our objectives were to assess the relationships between feed efficiency with liver morphometry and metabolic blood profile in feedlot beef cattle. METHODS: Two populations (A = 112 and B = 45) of steers were tested for feed efficiency...

Nutrition and the gut microbiome regulate many systems, including the immune, metabolic, and nervous systems. We propose that the host responds to deficiency (or sufficiency) of dietary and bacterial metabolites in a dynamic way, to optimize responses and survival. A family of G protein-coupled receptors (GPCRs) termed the metabolite-sensing GPCRs bind to various metabolites and transmit signals that are important for proper immune and metabolic functions. Members of this family include GPR43, GPR41, GPR109A, GPR120, GPR40, GPR84, GPR35, and GPR91...

Increased lipid levels in blood contribute to increasing the risk of diabetic complications. Glucagon exerts lipid lowering effects in diabetic state. However, the mechanism behind the lipid reduction by glucagon independent of glucose homeostasis is not well understood. We assessed the actions of glucagon on lipid modulation in blood and markers in liver in hyperlipidemic hamsters and rats. Male Sprague Dawley rats and Golden Syrian hamsters on a hyperlipidemic diet for 2 weeks were administered a single dose of glucagon by subcutaneous (SC, 150 and 300 µg/kg) or intracerebroventricular (ICV, 15 and 30 µg/animal) route...

Barcelona clinic liver cancer-stage C (BCLC-C) encompasses a broad spectrum of tumor burdens, liver function statuses, patient prognoses, and treatment strategies. Currently, sorafenib is the only recommended treatment for patients with BCLC-C and outcomes remain suboptimal. The aims of this study were to assess the heterogeneity of BCLC-C hepatocellular carcinoma (HCC) cases, propose a novel subclassification for these cases, and suggest optimal treatment strategies other than sorafenib.We retrospectively analyzed 196 consecutive BCLC-C HCC patients who were diagnosed and treated between January 2008 and December 2015...

BACKGROUND: Lipocalin-2 (Lcn2) is a multifunctional innate immune protein that exhibits antimicrobial activity by the sequestration of bacterial siderophores, regulates iron homeostasis, and augments cellular tolerance to oxidative stress. Studies in the murine model of colitis have demonstrated that Lcn2 deficiency exacerbates colitogenesis; however, the therapeutic potential of Lcn2 supplementation has yet to be elucidated. In light of its potential mucoprotective functions, we, herein, investigated whether expression of Lcn2 in the probiotic bacterium can be exploited to alleviate experimental colitis...

PPARα has been known to play a pivotal role in orchestrating lipid, glucose, and amino acid metabolism via transcriptional regulation of its target genes expression during energy deprivation. Recent evidence also suggesting PPARα is involved in bile acid metabolism, but how PPARα modulates the homeostasis of bile acids during fasting is still not clear. In a mechanistic study aiming to dissect the spectrum of PPARα target genes involved in metabolic response to fasting, we identified a novel mouse gene (herein named mL-STL) which shared extensive homology to Sult2a subfamily of a superfamily of cytosolic sulfotransferases, implying its potential function in sulfonation...

OBJECTIVE: In previous studies using oesophageal squamous cells from patients with Barrett's oesophagus (normal oesophageal squamous (NES)-B cells) and from patients without Barrett's oesophagus (NES-G cells), we showed that acid and bile salts induced caudal-related homeobox transcription factor 2 (CDX2) expression only in NES-B cells. CDX2, a transcription factor required to form intestinal epithelium, is a target of nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) signalling, which can be inhibited by aspirin...

REVIEW
Monica D Chow, Yi-Horng Lee, Grace L Guo
Nonalcoholic fatty liver disease is growing in prevalence worldwide. It is started by the presence of macrosteatosis on liver histology but is often clinically asymptomatic. However, it can progress into nonalcoholic steatohepatitis which is a more severe form of liver disease characterized by inflammation and fibrosis. Further progression leads to cirrhosis, which predisposes patients to hepatocellular carcinoma or liver failure. The mechanism by which simple steatosis progresses to steatohepatitis is not entirely clear...

BACKGROUND/AIMS: Platelets are essential mediators of hemostasis to avoid excessive blood loss. Cirrhosis and chronic liver diseases are characterized by alterations in hemostasis. Alterations in the secondary hemostasis have been well studied, while defects in primary hemostasis, especially the consequences of cholestatic liver disease on platelet function are not well defined. METHODS: After bile duct ligation (BDL) platelet activation and thrombus formation were analyzed in mice...

Observations in a previous study on biomarker responses in fish collected from urban creeks in Greenville, SC, indicated that there might be considerable differences in the expression of biotransformation enzymes in chub and sunfish species. To further investigate these species differences a dosing experiment was performed in which bluehead and creek chub (Nocomis leptocephalus and Semotilus atromaculatus), and redbreast sunfish, pumpkinseed, and bluegill (Lepomis auritus, L. gibbosus, and L. macrochirus) were injected with benzo[a]pyrene (BaP) as a model compound for common pollutants in urban creeks...

The adverse effects of elevated polybrominated diphenyl ether (PBDE) levels, reported in the blood of domestic dogs and cats, are considered to be of great concern. However, the tissue distribution of PBDEs and their derivatives in these animals is poorly understood. This study determined the concentrations and profiles of PBDEs, hydroxylated PBDEs (OH-PBDEs), methoxylated PBDEs (MeO-PBDEs), and 2,4,6-tri-bromophenol (2,4,6-tri-BPh) in the blood, livers, bile, and brains of dogs and cats in Japan. Higher tissue concentrations of PBDEs were found in cats, with the dominant congener being BDE209...

We have proposed and validate an in vitro probiotic selection, based on enzymatic potentialities associated to well-established probiotic functional properties. A new Bacillus subtilis HB2 isolate, selected based on its high extracellular enzyme production, was chosen as a probiotic candidate for application as animal feed supplement. The HB2 strain showed an excellent acid and bile salts tolerance, a strong adhesion to chick enterocytes and produced antimicrobials against pathogens. An in vivo trial in poultry farming was conducted to evaluate the HB2 probiotic performance...
