Changes in salivary microbiota due to gastric cancer resection and its relation to gastric fluid microbiota

Scientific Reports, 2023
Gastric cancer is one of the leading causes of death worldwide, and resections are performed to cure the disease. We have previously reported the changes in the gastric microbiota after gastric cancer resection, which may be associated with the oral ...

Nanocellulose Alleviates Intrahepatic Cholestasis of Pregnancy via Gut Microbiota‐Mediated Bile Acid Homeostasis

Advanced Science, EarlyView.
Nanocellulose, derived from microcrystalline cellulose (MCC) through sulfuric acid hydrolysis or mechanical grinding to produce CNC or CNF, was tested in a rat ICP model. Particularly, CNF improved gut microbiota composition, reduced secondary bile acid metabolism, and restored bile acid homeostasis through modulation of the gut–liver axis.

Nutritional influences on oral infections: the oral microbiota modulation.

Rio de Janeiro Dental Journal (Revista Científica do CRO-RJ), 2020
Introduction: The oral microbiota has approximately 700 symbiotic microorganisms responsible for oral health homeostasis. However, changes in oral microbiota can generate dysbiotic processes that favor the worsening of infections such as caries and periodontal disease. These oral infections, in addition to systemic involvement, can compromise the teeth

Icariin Enhances the Enzymatic Activity of N‐acetylgalactosaminidase to Augment Akkermansia Abundance in Gut Microbiota for Improved PD‐1 Blockade Efficacy in Tumor Suppression

Advanced Science, EarlyView.
Icariin promoted the growth of Akk by enhancing the activity of N‐acetylgalactosaminidase (Amuc_0920), which enhanced mucin utilization and provided a favorable nutrient environment for bacterial growth. This icariin‐mediated enrichment of Akk further reshaped the tumor microenvironment and promoted CD8+ T cell infiltration, ultimately synergizing with

The interaction between oral microbiota and gut microbiota in atherosclerosis

Frontiers in Cardiovascular Medicine
Atherosclerosis (AS) is a complex disease caused by multiple pathological factors threatening human health-the pathogenesis is yet to be fully elucidated. In recent years, studies have exhibited that the onset of AS is closely involved with oral and gut microbiota, which may initiate or worsen atherosclerotic processes through several mechanisms.

A Microbial Lipid‐ATP Synthase Axis Fuels NK Cell Antitumor Activity

Advanced Science, EarlyView.
This study focuses on the mechanism by which gut microbiota‐derived outer membrane vesicles (OMVs) regulate NK cell antitumor activity. B. intestinalis is identified to decrease extra‐intestinal tumor growth via its OMVs enriched in sphingosine (SP).

The oral microbiota change in oral cancer – a preliminary study

Annals of Agricultural and Environmental Medicine
The relationship between oral bacteria and oral squamous cell carcinoma (OSCC) is not yet fully understood. This study aimed to profile the microbiota composition at tumour sites versus adjacent normal tissues in the oral mucosa of 10 OSCC patients using a qPCR Array.We recruited 10 OSCC patients (8 men and 2 women, aged 40 to 89 years) from the ...

IL‐7R‐Enriched Extracellular Vesicles From the Thymus Drive Colitis via Promoting Neutrophil Extracellular Trap Formation

Advanced Science, EarlyView.
Inflammatory bowel disease (IBD) pathogenesis remains unclear. This study reveals that thymus‐originated IL‐7R‐enriched extracellular vesicles exacerbate colitis by promoting neutrophil extracellular traps via a thymus‐gut axis, uncovering an inter‐organ communication mechanism in inflammatory bowel disease pathogenesis.

Modulation of oral and faecal microbiota by cheese: Relationships with sweet taste sensitivity in rat.

Journal of Functional Foods
The oral cavity contains a large community of microorganisms known as the oral microbiota. This oral microbiota can be modulated by the consumption of fermented food (FF) in rat but the impact of FF consumption on the microbiota (oral and faecal) of ...
