Article Abstract
Introduction: The oral squamous cell carcinoma (OSCC) is detrimental to patients' physical and mental health. The prognosis of OSCC depends on the early diagnosis of OSCC in large populations.
Objectives: Here, the present study aimed to develop an early diagnostic model based on the relationship between OSCC and oral microbiota.
Methods: Overall, 164 samples were collected from 47 OSCC patients and 48 healthy individuals as controls, including saliva, subgingival plaque, the tumor surface, the control side (healthy mucosa), and tumor tissue. Based on 16S rDNA sequencing, data from all the five sites, and salivary samples only, two machine learning models were developed to diagnose OSCC.
Results: The average diagnostic accuracy rates of five sites and saliva were 98.17% and 95.70%, respectively. Cross-validations showed estimated external prediction accuracies of 96.67% and 93.58%, respectively. The false-negative rate was 0%. Besides, it was shown that OSCC could be diagnosed on any one of the five sites. In this model, , , , , and species exhibited strong correlations with OSCC.
Conclusion: This study provided a noninvasive and inexpensive way to diagnose malignancy based on oral microbiota without radiation. Applying machine learning methods in microbiota data to diagnose OSCC constitutes an example of a microbial assistant diagnostic model for other malignancies.

Metabolic interplay of SCFA's in the gut and oral microbiome: a link to health and disease.

Short-chain fatty acids (SCFAs), primarily acetate (C2), propionate (C3), and butyrate (C4), are crucial microbial metabolites formed by the fermentation of dietary fibers by gut microbiota in the colon. These SCFAs, characterized by fewer than six carbon atoms, serve as an essential energy source for colonic epithelial cells and contribute approximately 10% of the body's total energy requirement. They are central to maintaining gut health through multiple mechanisms, including reinforcing intestinal barrier function, exerting anti-inflammatory effects, regulating glucose and lipid metabolism, and influencing host immune responses.

Metabolic-associated fatty liver disease (MAFLD), linked to lipid dysregulation, poses global health risks. 2,2',3,4,4',5'-hexachlorobiphenyl (PCB138) is a persistent organic pollutant that poses potential threats to liver health due to its environmental persistence and bioaccumulation. Theabrown (TB), a natural compound extracted from black tea, exhibits lipid-lowering and antioxidant properties, but its protective effects on PCB138-induced liver injury have not been thoroughly investigated.

Chronic inflammation and microbial dysbiosis have been implicated in the development of head and neck squamous cell carcinoma (HNSCC), particularly oral cavity squamous cell carcinoma (OSCC). Periodontitis is a common chronic inflammatory disease characterized by the progressive destruction of tooth-supporting structures. While periodontitis Has been associated with an increased risk of OSCC in epidemiological and mechanistic studies, the strength of this association is unclear.

Turmeric (Curcuma longa) exhibits anti-obesity properties, yet its low water solubility limits bioavailability. In this study, a water-dispersible turmeric rhizome extract (WDTE) was developed using nano-dispersion technology with maltodextrin as a wall material and characterized by UPLC-QTOF-MS, dynamic light scattering, and zeta potential analysis. The WDTE contained 10 identified metabolites, including five diarylheptanoids such as curcumin, demethoxycurcumin, and bisdemethoxycurcumin, with curcumin quantified at 7.

This study aimed to assess the impact of yeast beta-1,3/1,6-glucans (BG) on apparent digestibility coefficients (ADC) of nutrients, intestinal fermentative metabolites, fecal microbiota profile, and immune and antioxidant variables in puppies before and after surgical challenge. Two treatments were evaluated: control, without, and test, with oral supplementation of 65 mg/kg body weight/day of purified BG from Saccharomyces cerevisiae for 120 days. For this, 16 growing Beagle dogs were distributed in a completely randomized design (n = 8/treatment).
