Bacterial sex in dental plaque

Journal of Oral Microbiology, 2013
Genes are transferred between bacteria in dental plaque by transduction, conjugation, and transformation. Membrane vesicles can also provide a mechanism for horizontal gene transfer. DNA transfer is considered bacterial sex, but the transfer is not parallel to processes that we associate with sex in higher organisms.

Antibacterial effects of natural compounds on biofilm formation of Streptococcus mutans

Clinical and Experimental Dental Research, Volume 8, Issue 6, Page 1426-1433, December 2022., 2022
Abstract Streptococcus mutans is the main cariogenic pathogen in the oral cavity, considered to contribute toward oral diseases. S. mutans is predominantly entrapped in plaque biofilms. Objectives In this study, we surveyed the antibacterial activity of natural compounds in terms of the biofilm production of S. mutans. Material and Methods We extracted

Towards Earlier Detection of Oral Diseases On Smartphones Using Oral and Dental RGB Images [PDF]

arXiv, 2023
Oral diseases such as periodontal (gum) diseases and dental caries (cavities) affect billions of people across the world today. However, previous state-of-the-art models have relied on X-ray images to detect oral diseases, making them inaccessible to remote monitoring, developing countries, and telemedicine.

Tongxinluo enhances the effect of atorvastatin on the treatment of atherosclerosis with chronic obstructive pulmonary disease by maintaining the pulmonary microvascular barrier

Food Science &Nutrition, Volume 11, Issue 1, Page 390-407, January 2023., 2023
COPD aggravates AS, possibly through the destruction of pulmonary microvascular barrier function; thus, lung inflammation triggers systemic inflammation. In treating COPD with AS, TXL enhances the antiatherosclerotic effect of Ato, protecting the pulmonary microvascular barrier.

Quasi-static responses of marine mussel plaques attached to deformable wet substrates under directional tensions [PDF]

, 2023
Quantifying the response of marine mussel plaque attachment on wet surfaces remains a significant challenge to a mechanistic understanding of plaque adhesion. Here, we developed a customised microscopy system combined with two-dimensional (2D) in-situ digital image correlation (DIC) to quantify the in-plane deformation of a deformable substrate that ...
