PURPOSE OF THE REVIEW: To review what intestinal permeability is and how it is measured, and to summarise the current evidence linking altered intestinal permeability with the development of hypertension. RECENT FINDINGS: Increased gastrointestinal permeability, directly measured in vivo, has been demonstrated in experimental and genetic animal mod...

This study aimed to investigate the effects of supplementation with polysaccharide-rich Aloe arborescens, which has anti-inflammatory, immunostimulant, antibacterial, and antioxidant properties, on the rumen, rectum and milk microbiomes of dairy cows during the transition period. This dietary supplementation appears to exert a significant influence...
BACKGROUND: Recent advances have significantly expanded our understanding of the gut microbiome's influence on host physiology and metabolism. However, the specific role of certain microorganisms in gestational health and fetal development remains underexplored. OBJECTIVE: This study investigates the impact of Bifidobacterium breve UCC2003 on fetal...
The rising prevalence of liver diseases related to obesity and excessive use of alcohol is fuelling an increasing demand for accurate biomarkers aimed at community screening, diagnosis of steatohepatitis and significant fibrosis, monitoring, prognostication and prediction of treatment efficacy. Breakthroughs in omics methodologies and the power of ...

The role of gut-brain axis functioning gains growing attention in research on the pathophysiology of major depressive disorders. Here, especially consequences of altered microbiota composition on tryptophan metabolism resulting in altered serotonergic neurotransmission in the central nervous system (CNS) have reached a central position. Previous re...
Bacteroides fragilis is a Gram-negative commensal bacterium commonly found in the human colon, which differentiates into two genomospecies termed divisions I and II. Through a comprehensive collection of 694 B. fragilis whole genome sequences, we identify novel features distinguishing these divisions. Our study reveals a distinct geographic distrib...
BACKGROUND: Chronic exposure to microorganisms inside homes can impact respiratory health. Few studies have used advanced sequencing methods to examine adult respiratory outcomes, especially continuous measures. We aimed to identify metagenomic profiles in house dust related to the quantitative traits of pulmonary function and airway inflammation i...
Iron is essential for life, but its imbalances can lead to severe health implications. Iron deficiency is the most common nutrient disorder worldwide, and iron disregulation in early life has been found to cause long-lasting behavioral, cognitive, and neural effects. However, little is known about the effects of dietary iron on gut microbiome funct...
Highlights: • Desert ecosystems are subjected to high water stress, limiting plant growth. • Drought increases the abundance of drought-tolerant Actinobacteria and Acidobacteria. • Microbiota of Haloxylon salicornicum roots and rhizosphere is responsive to water. • Symbionts taxa are differentially expressed following watering. • Little studied dar...
As the microbiome field moves from descriptive and associative research to mechanistic and interventional studies, being able to account for all confounding variables in the experimental design, which includes the maternal effect1, cage effect2, facility differences3, as well as laboratory and sample handling protocols4, is critical for interpretab...
