OBJECTIVE: To determine the effects of exogenous glucagon-like peptide-2 (GLP-2), with or without massive distal bowel resection, on adaptation of jejunal mucosa, enteric neurons, gut hormones and tissue reserves in rats. BACKGROUND: GLP-2 is a gut hormone known to be trophic for small bowel mucosa, and to mimic intestinal adaptation in short bowel syndrome (SBS). However, the effects of exogenous GLP-2 and SBS on enteric neurons are unclear. METHODS: Sprague Dawley rats were randomized to four treatments: Transected Bowel (TB) (n = 8), TB + GLP-2 (2...

Effect of alkyl chain spacer length between the charged groups (CSL) in zwitterionic poly(sulfobetaine) (PSB) brushes on hydration state was investigated. PSB brushes with ethyl (PMAES), propyl (PMAPS), or butyl (PMABS) CSL were prepared by surface-initiated atom transfer radical polymerization on silicon wafers. Hydration states of the PSB brushes in aqueous solutions and/or humid vapor were investigated by contact angle measurement, infrared spectroscopy, AFM observation, and neutron reflectivity. The PSB brushes were swollen in deionized water due to the hydration of the charged groups in SBs leading to the reduction of hydrated PSB brushes/water interfacial free energy...

BACKGROUND: Intestinal failure-associated liver disease (IFALD) causes significant morbidity in neonates with short bowel syndrome (SBS) dependent on parenteral nutrition (PN). Resected ileum, with loss of the ileocecal valve (ICV), is the most common anatomy in SBS, yet its impact on IFALD has not been adequately studied. METHODS: Neonatal piglets were randomized to 75% intestinal resection with jejunocolic anastomosis (JC, n = 12), 75% resection with jejunoileal anastomosis and intact ICV (JI, n = 13), PN-fed sham (sham, n = 14), or sow-fed control (SF, n = 8)...

BACKGROUND: Distraction enterogenesis has been investigated as a novel treatment for short bowel syndrome (SBS). With variable intestinal sizes, it is critical to determine safe, translatable spring characteristics in differently sized animal models before clinical use. Nitinol springs have been shown to lengthen intestines in rats and pigs. Here, we show spring-mediated intestinal lengthening is scalable and feasible in a murine model. MATERIALS AND METHODS: A 10-mm nitinol spring was compressed to 3 mm and placed in a 5-mm intestinal segment isolated from continuity in mice...

The redox-responsive regulator SurR in the hyperthermophilic archaea Pyrococcus furiosus and Thermococcus kodakarensis binds to the SurR-binding consensus sequence (SBS) by responding to the presence of elemental sulfur. Here we constructed a surR gene disruption strain (DTS) in T. kodakarensis, and identified the genes that were under SurR control by comparing the transcriptomes of DTS and parent strains. Among these genes, transcript levels of ferredoxin:NADP(+) oxidoreductases 1 and 2 (FNOR1 and FNOR2) genes displayed opposite responses to surR deletion, indicating that SurR repressed FNOR1 transcription while enhancing FNOR2 transcription...

The Society of Biology of Strasbourg (SBS) is a learned society that was created in 1919 based on the model of the Society of Biology of which it is a subsidiary. Like its Parisian colleague, SBS aims at diffusing and promoting scientific knowledge in biology. To achieve this goal, SBS initiated since its creation a dialogue interface between researchers in biology and physicians, and more recently with other scientific disciplines, industry and the civil society. At the dawn of its first century, the Society of Biology of Strasbourg must continue to reinvent itself to pursue its development and to fulfil its mission of sharing scientific knowledge...

Teduglutide (TG) is approved for the treatment of parenteral nutrition (PN)-dependent adult patients with short bowel syndrome (SBS). Its well-known adverse effect is expedited growth of colon polyps and potential formation of new polyps. Apart from animal studies, de novo development of duodenal polyps in a patient during TG therapy has not been reported in the literature. We report a case of a 71-year-old man with SBS on TG who developed multiple new duodenal polyps that were found incidentally during a diagnostic endoscopy...

BACKGROUND: Short bowel syndrome (SBS) is a common indication for home parenteral nutrition (HPN). Oral rehydration solutions (ORSs) have the ability to supplement or reduce HPN dependence. However, ORSs have suffered from poor taste profiles, making long-term consumption and compliance unlikely. The goal of the current study was to assess the taste and compliance of 2 ORSs among patients with SBS requiring HPN. METHODS: All participants with SBS receiving HPN with anticipated duration >3 months were offered enrollment: 31 participants met inclusion criteria; 3 declined enrollment; and 28 were randomized to receive a modified World Health Organization ORS (group A) or a commercially available ORS (DripDrop; group B)...
