AI Article Synopsis

  • The study examined how polysaccharides from a specific source are digested in the salivary and gastrointestinal (GI) systems, finding that salivary amylase did not affect them.
  • During gastric digestion, the molecular weight of these polysaccharides decreased significantly in the first half-hour, and the amount of reducing sugars increased throughout GI digestion.
  • The fermentation process resulted in a lower pH due to the production of short-chain fatty acids (SCFAs), indicating that these polysaccharides are actively digested and beneficial in the human large intestine.

Article Abstract

salivary and gastrointestinal (GI) digestion and fermentation of polysaccharides extracted from were investigated in this study. Salivary amylase showed no influence on polysaccharides (DAP). The molecular weight of DAP decreased dramatically during the first 0.5 h of gastric digestion, and then reduced steadily during the subsequent GI tract consumption. The content of reducing sugars increased steadily during GI digestion. Only released free mannose of DAP was detectable by gas chromatography-mass spectrometry analysis during the first 12 h of fermentation, which was contributed by fecal microbiota metabolism. In terms of the fermentation pattern, the pH dropped significantly due to the formation of six types of short-chain fatty acids (SCFAs). This study demonstrates that polysaccharides extracted from can be digested by the GI tract and are physiologically active in the human large bowel by lowering the pH of the large intestinal environment and promoting the production of SCFAs.

Background/purpose: Dysbiosis of oral microbiota has been reported in late stage of chronic hepatitis B (CHB) infection with cirrhosis. CHB is characterized by the constant virus-induced liver injury which may lead to liver cirrhosis and hepatocellular carcinoma (HCC). However, some patients show normal liver function without antiviral treatment, associating with favourable prognosis.

SARS-CoV-2 is the viral pathogen responsible for COVID-19. Although morbidity and mortality frequently occur as a result of lung disease, the gastrointestinal (GI) tract is recognized as a primary location for SARS-CoV-2. Connections and interactions between the microbiome of the gut and respiratory system have been linked with viral infections via what has been referred to as the 'gut-lung axis' with potential aerodigestive communication in health and disease.

Autonomic dysfunction is a common and early complication among patients with systemic sclerosis, suggesting that it may play a role in the pathogenesis of the disease and be a potential target for therapeutic interventions. Although the true prevalence of autonomic dysfunction among patients with systemic sclerosis is still unclear, it is estimated that as many as 80% of patients may be affected. Autonomic dysfunction may lead to widespread multi-organ dysfunction through its effects on the cardiovascular system, gastrointestinal tract, urinary tract, sweat and salivary glands, and pupils.

Background And Aims: Oral microbiota may contribute to the development of upper gastrointestinal (UGI) disorders. We aimed to study the association between the microbiome of saliva, subgingival and buccal mucosa, and UGI disorders, particularly precancerous lesions. We also aimed to determine which oral site might serve as the most effective biomarker for UGI disorders.

Decreased saliva production due to salivary gland damage can result in difficulty speaking and swallowing, significantly reducing quality of life for head and neck cancer patients receiving radiotherapy. It is therefore imperative that treatment options are available to mitigate the effects of these debilitating side effects. D-limonene, a naturally occurring terpene, has shown protective effects on saliva production during radiotherapy treatment of mice, however the lipophilic nature of the molecule has necessitated a high oral dose to facilitate sufficient absorption.
