Saturated Partial Embeddings of Planar Graphs

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT In this work, we study how far one can deviate from optimal behavior when embedding a planar graph. For a planar graph G $G$, we say that a plane subgraph H ⊆ G $H\subseteq G$ is a plane‐saturated subgraph if adding any edge (possibly with new vertices) to H $H$ would either violate planarity or make the resulting graph no longer a subgraph of

Acupuncture Relieves Anxiety and Depression in Diarrhea-Predominant Irritable Bowel Syndrome Rats Through the Gut–Brain Axis

open access: yesGastroenterology Research and Practice
Anxiety and depression frequently occur in patients with irritable bowel syndrome (IBS), a disordered long-term digestive disease affecting the stomach and intestine. The symptoms include stomach cramps, bloating, diarrhea/constipation, or both.

Obstructions for Homomorphisms to Odd Cycles in Series‐Parallel Graphs

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT For a graph H $H$, an H $H$‐colouring of a graph G $G$ is a vertex mapping ϕ : V ( G ) → V ( H ) $\phi :V(G)\to V(H)$ such that adjacent vertices are mapped to adjacent vertices. A graph G $G$ is C 2 k + 1 ${C}_{2k+1}$‐critical if G $G$ has no C 2 k + 1 ${C}_{2k+1}$‐colouring but every proper subgraph of G $G$ has a C 2 k + 1 ${C}_{2k+1 ...

Low‐FODMAP diet for pediatric patients with disorders of gut‐brain interaction: A systematic review and meta‐analysis

open access: yesJournal of Parenteral and Enteral Nutrition, EarlyView.
Abstract Objectives The role of a low‐FODMAP diet in pediatric disorders of gut–brain interaction (DGBIs), particularly irritable bowel syndrome (IBS) and functional abdominal pain (FAP), is unclear. This review synthesized evidence on its efficacy in children and adolescents with IBS or FAP.

Gut microbiome in pediatric acute pancreatitis and Crohn's disease versus irritable bowel syndrome and healthy controls

open access: yesJournal of Pediatric Gastroenterology and Nutrition, EarlyView.
Abstract Objectives Pediatric acute pancreatitis (AP), Crohn's disease (CD), and irritable bowel syndrome (IBS) are associated with gut dysbiosis, but differences and similarities between conditions are unknown. We hypothesized that gut microbial ecology would differ across these disorders. Methods Stool was collected from 120 subjects (AP [n = 30], CD

The mechanism of patchouli alcohol in treating IBS-D based on BMP-Smad pathway

open access: yesBiomedicine & Pharmacotherapy
Irritable Bowel Syndrome (IBS) is a chronic gastrointestinal condition, and diarrhea predominant (IBS-D) is the most common subtype.The enteric nervous system (ENS) regulates major gastrointestinal motility and function, and the intestinal neuronal BMP-SMAD signaling pathway is closely related to intestinal motility.
