Micro‐ and nanoplastics in gastrointestinal disorders: Mapping the translational gap between exposure, biomonitoring, and pathogenic mechanisms

BMEMat, EarlyView.
This review highlights critical “translational gaps” in understanding micro‐ and nanoplastics impacts on gastrointestinal diseases, bridging exposure, detecting, and mechanistic toxicology. Abstract Micro‐ and nanoplastics (MNPs) have become pervasive environmental contaminants with increasing evidence linking them to adverse health outcomes.

Decreased expression of breast cancer resistance protein in the duodenum in patients with obstructive cholestasis [PDF]

, 2006
Background/Aims: The expression of transporters involved in bile acid homeostasis is differentially regulated during obstructive cholestasis. Since the drug efflux transporter breast cancer resistance protein (BCRP) is known to transport bile acids, we ...

How bad is bile acid diarrhoea : an online survey of patient-reported symptoms and outcomes

, 2017
Objectives Bile acid diarrhoea (BAD) is an underdiagnosed condition producing diarrhoea, urgency and fear of faecal incontinence. How patients experience these symptoms has not previously been studied.

Comparative genomics of lactic acid bacteria reveals a niche-specific gene set [PDF]

, 2009
peer-reviewedBackground: The recently sequenced genome of Lactobacillus helveticus DPC4571 1 revealed a dairy organism with significant homology (75% of genes are homologous) to a probiotic bacteria Lb. acidophilus NCFM 2. This led us to hypothesise that

Feedback regulation of bile acid biosynthesis in the rat

Journal of Lipid Research, 1969
The hepatic biosynthesis of bile salts in the rat has been shown to be controlled homeostatically by the quantity of bile salt returning to the liver via the portal circulation. The feedback mechanism was demonstrated in two kinds of experiments.
