The microbial infections involving the craniofacial skeleton, particularly maxilla and mandible, have direct relationship with the dental biofilm, with predominance of obligate anaerobes. In some patients, these infections may spread to bone marrow or facial soft tissues, producing severe and life-threatening septic conditions. In such cases, local treatment associated with systemic antimicrobials should be used in order to eradicate the sources of contamination. This paper discuss the possibility of spread of these infections and their clinical implications for dentistry, as well as their etiology and aspects related to microbial virulence and pathogenesis.

Ruminococcus gnavus is a gut bacterium found in > 90% of healthy individuals, but its increased abundance is also associated with chronic inflammatory diseases, particularly Crohn's disease. Nevertheless, its global distribution and intraspecies genomic variation remain understudied. By surveying 12,791 gut metagenomes, we recapitulated known associations with metabolic diseases and inflammatory bowel disease.

Small-molecule pectin (SMP) extracted from the leaves of Premna ligustroides Hemsl, with a molecular weight range of 5000-35,000 Da, has demonstrated anti-inflammatory and lipid-lowering properties in vitro. This study explored the effects of SMP on hypercholesterolemia in mice, with a focus on inflammation, lipid profiles, and cholesterol metabolism. Mice received SMP at doses of 607, 303, and 152 mg/kg body weight.

Ethnopharmacological Relevance: Inonotus obliquus has also been used as a traditional folk medicine in Europe and Northeastern China to treat metabolic diseases. Betulinic acid (BA) is a major ingredient with anti-diabetic property derived from I. obliquus, however, its bioavailability is limited.

Type 1 diabetes (T1D) is a complex disease triggered by a combination of genetic and environmental factors, where abnormal autoimmune responses lead to progressive damage of the pancreatic β cells and severe glucose metabolism disorder. Recent studies have increasingly highlighted the close link between gut microbiota dysbiosis and the development of T1D. This review delves into existing population studies to explore the intricate interactions between the gut microbiota and the immune and metabolic homeostasis in T1D.

Exposure to harmful microbiomes and antibiotic resistance genes (ARGs) can negatively affect human health. However, the contribution of vegetation and soils to the airborne microbiota transferred indoors (AMTI) remains unclear. We used our newly-developed airborne microbial sampler (VenTube) to collect AMTI samples from 72 neighborhoods in Shanghai.
