Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

365
Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Role Of Notch Signalling In Intestinal Stem Cell Renewal01:12

Role Of Notch Signalling In Intestinal Stem Cell Renewal

2.1K
Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...

Glucose Absorption Into the Small Intestine01:26

Glucose Absorption Into the Small Intestine

31.8K
Complex carbohydrates consumed cannot be absorbed into the small intestine in their original form. First, they must be hydrolyzed to a monosaccharide form such as glucose or galactose. These monosaccharides are then transported across the intestinal membrane and into the blood via transcellular transport. The intestinal epithelial cells allow the movement of these monosaccharides with a defined 'entry' through membrane transporter proteins present on their apical membrane and...

Area of Science:

  • Food Science
  • Nutritional Biochemistry
  • Microbiology

Background:

  • Resistant starch shows potential benefits for hypertension, cardiovascular health, and enteric illnesses.
  • The impact of resistant starch on intestinal physiological functions is gaining significant research interest.

Purpose of the Study:

  • To analyze the physicochemical properties of different types of buckwheat-resistant starch.
  • To evaluate the influence of resistant starch on mouse intestinal physiological functions, including defecation and gut microbiota.
  • To establish an effective preparation method for enhancing buckwheat-resistant starch quality.

Main Methods:

  • Physicochemical analysis of buckwheat-resistant starch, including crystalline properties, amylose content, and anti-digestibility.
  • Evaluation of intestinal physiological functions in mice, focusing on defecation and microbial populations.
  • Preparation of buckwheat-resistant starch using acid hydrolysis treatment (AHT) and autoclaving enzymatic debranching treatment (AEDT).

Main Results:

  • Buckwheat-resistant starch crystalline structure shifted from A to B + V after AHT and AEDT.
  • AEDT resulted in higher amylose content and stronger anti-digestibility compared to AHT and raw buckwheat.
  • Buckwheat-resistant starch was found to promote intestinal movement and regulate the quantity of intestinal microbes.

Conclusions:

  • An effective method for improving buckwheat-resistant starch quality was demonstrated.
  • Buckwheat-resistant starch plays a role in adjusting intestinal flora distribution.
  • This research supports the use of buckwheat-resistant starch for maintaining body health through gut health modulation.
