Current Trends, Future Prospects and Constraints of Whole Microalgae and Their Fractions as a Functional Feed Ingredient for Animals

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Microalgae are a highly diverse group of unicellular organisms that grow in a wide range of aquatic environments and are widely used as dietary supplements for both human and animal applications. Microalgae are rich in lipids, proteins, carbohydrates and other valuable bioactive components such as pigments, antioxidants and vitamins.

Late Stage Mannan Metabolism in Cellvibrio japonicus Requires the Combined Action of a Mannosyl‐Glucose Phosphorylase and a Mannobiose Epimerase

Molecular Microbiology, EarlyView.
Model for the non‐PTS utilization of manno‐oligosaccharides by Cellvibrio japonicus. The Mgp130A and EpiA enzymes are essential for the utilization of mannose residues. ABSTRACT Manno‐oligosaccharides and their metabolism play important roles in gut health, pharmaceutical development, and renewable chemical production.

Differential stability and dynamics of DNA-based and RNA-based coacervates affect non-enzymatic RNA chemistry

Nature Communications
The RNA-peptide world hypothesis postulates the early co-evolution of RNA and peptides that led to the emergence of non-enzymatic RNA replication and peptide synthesis.

A Review of the Mechanisms of Action of the Herbal Medicine, STW 5‐II, Underlying Its Efficacy in Disorders of Gut–Brain Interaction

Neurogastroenterology &Motility, EarlyView.
The pathophysiology of functional dyspepsia and irritable bowel syndrome includes altered motility, secretion, sensitivity to sensory signals, impaired epithelial barrier function, inflammation, and gut dysbiosis. The phytomedicine, STW 5‐II, represents a multi‐targeted approach, addressing these pathophysiologies.

The oral microbiota and periodontal health in orthodontic patients

Periodontology 2000, EarlyView.
Abstract The oral microbiota develops within the first 2 years of childhood and becomes distinct from the parents by 4 years‐of‐age. The oral microbiota plays an important role in the overall health/symbiosis of the individual. Deviations from the state of symbiosis leads to dysbiosis and an increased risk of pathogenicity.
