Intestinal microbial profiles of wild Alaskan rainbow trout () characterized by 16S rRNA amplicon data.

Rainbow trout () is a dominant aquaculture species of the Salmonidae family, native only to the North Pacific. Recently, the gut microbiome has been shown to reflect the health status and responses to environmental changes in farmed fish. In this analysis we investigated the microbiome composition of the intestinal tract in 20 wild-caught rainbow trout specimens sampled in Alaska, USA.

Genomic context determines the effect of DNA methylation on gene expression in the gut epithelium of Atlantic salmon ().

The canonical view of DNA methylation, a pivotal epigenetic regulation mechanism in eukaryotes, dictates its role as a suppressor of gene activity, particularly within promoter regions. However, this view is being challenged as it is becoming increasingly evident that the connection between DNA methylation and gene expression varies depending on the genomic location and is therefore more complex than initially thought. We examined DNA methylation levels in the gut epithelium of Atlantic salmon () using whole-genome bisulfite sequencing, which we correlated with gene expression data from RNA sequencing of the same gut tissue sample (RNA-seq).

Peritonitis associated with continuous ambulatory peritoneal dialysis: the pseudo-surgical abdomen.

In this work, 12 patients undergoing continuous ambulatory peritoneal dialysis with peritonitis showing clinical symptomatology of "acute surgical abdomen" were studied. The infective cause of peritonitis was Staphylococcus epidermidis (eight cases) and Staphylococcus aureus (four cases). All patients, under strict and continuous observation, were managed with conventional chemotherapy and showed improvement within 6 to 24 hours.
