Perspective: Nutrition's Next Chapter - Bioactive Gaps and the Microbiome-Mitochondria Axis.

Food has the power to heal. Our bodies transform and are transformed by the elements in food, and the adage that we are what we eat is true. The twentieth century nutrition science focused on decoding the processes and building blocks of this transformation-proteins, fats, carbohydrates, vitamins, and minerals.

A microbiome-targeting fibre-enriched nutritional formula is well tolerated and improves quality of life and haemoglobin A1c in type 2 diabetes: A double-blind, randomized, placebo-controlled trial.

Aims: To investigate a prebiotic fibre-enriched nutritional formula on health-related quality of life and metabolic control in type 2 diabetes.

Materials And Methods: This was a 12-week, double-blind, placebo-controlled study with an unblinded dietary advice only comparator arm. Participants were randomized 2:1:1 to a prebiotic fibre-enriched nutritional formula (Active), a placebo fibre-absent nutritional formula (Placebo), or non-blinded dietary advice alone (Diet).

Patients Perceive Clinical Benefit with the Specific Carbohydrate Diet for Inflammatory Bowel Disease.

Background: Recent studies suggest that dietary therapy may be effective for patients with inflammatory bowel disease (IBD), but limited published data exist on the usage and efficacy of dietary therapy.

Aim: To evaluate the perspective of IBD patients using the specific carbohydrate diet (SCD).

Methods: An anonymous online survey was conducted using REDCap, a Web-based survey tool.

GUTSS: An Alignment-Free Sequence Comparison Method for Use in Human Intestinal Microbiome and Fecal Microbiota Transplantation Analysis.

Background: Comparative analysis of gut microbiomes in clinical studies of human diseases typically rely on identification and quantification of species or genes. In addition to exploring specific functional characteristics of the microbiome and potential significance of species diversity or expansion, microbiome similarity is also calculated to study change in response to therapies directed at altering the microbiome. Established ecological measures of similarity can be constructed from species abundances, however methods for calculating these commonly used ecological measures of similarity directly from whole genome shotgun (WGS) metagenomic sequence are lacking.

The intestinal microbiome, barrier function, and immune system in inflammatory bowel disease: a tripartite pathophysiological circuit with implications for new therapeutic directions.

We discuss the tripartite pathophysiological circuit of inflammatory bowel disease (IBD), involving the intestinal microbiota, barrier function, and immune system. Dysfunction in each of these physiological components (dysbiosis, leaky gut, and inflammation) contributes in a mutually interdependent manner to IBD onset and exacerbation. Genetic and environmental risk factors lead to disruption of gut homeostasis: genetic risks predominantly affect the immune system, environmental risks predominantly affect the microbiota, and both affect barrier function.

Low Level Engraftment and Improvement following a Single Colonoscopic Administration of Fecal Microbiota to Patients with Ulcerative Colitis.

Objective: Fecal microbiota transplantation (FMT) is an investigational treatment for diseases thought to involve alterations in the intestinal microbiota including ulcerative colitis (UC). Case reports have described therapeutic benefit of FMT in patients with UC, possibly due to changes in the microbiota. We measured the degree to which the transplanted microbiota engraft following FMT in patients with UC using a donor similarity index (DSI).

Fecal microbial transplant effect on clinical outcomes and fecal microbiome in active Crohn's disease.

Background: Crohn's disease (CD) is a chronic idiopathic inflammatory intestinal disorder associated with fecal dysbiosis. Fecal microbial transplant (FMT) is a potential therapeutic option for individuals with CD based on the hypothesis that changing the fecal dysbiosis could promote less intestinal inflammation.

Methods: Nine patients, aged 12 to 19 years, with mild-to-moderate symptoms defined by Pediatric Crohn's Disease Activity Index (PCDAI of 10-29) were enrolled into a prospective open-label study of FMT in CD (FDA IND 14942).

The microbiome and inflammatory bowel disease: is there a therapeutic role for fecal microbiota transplantation?

One hypothesis for the etiology of inflammatory bowel disease is that an altered or pathogenic microbiota causes inflammation in a genetically susceptible individual. Understanding the microbiota's role in the pathogenesis of the disease could lead to new IBD treatments aimed at shifting the bacteria in the gut back to eubiosis. Probiotics have some efficacy in the treatment of ulcerative colitis (UC), but our current repertoire is limited in potency.

Buffer optimization of thermal melt assays of Plasmodium proteins for detection of small-molecule ligands.

In the past decade, thermal melt/thermal shift assays have become a common tool for identifying ligands and other factors that stabilize specific proteins. Increased stability is indicated by an increase in the protein's melting temperature (Tm). In optimizing the assays for subsequent screening of compound libraries, it is important to minimize the variability of Tm measurements so as to maximize the assay's ability to detect potential ligands.
