Association between periodontal disease and malignant soft tissue sarcomas.

Objective: Malignant soft tissue sarcoma (MSTS) is a rare disease, but is seen in patients undergoing orthopedic surgery. Although the association of periodontal disease with various cancers occurring in the oral cavity, gastrointestinal tract, lungs, and prostate, has been reported, the association between periodontal disease and MSTS remains unclear. This study investigated the association between periodontal disease and MSTS in patients undergoing orthopedic surgery.

Surface-expressed phosphoglycerate mutase of Candida albicans binds to salivary DMBT1.

Candida albicans colonizes oral tissues and causes infectious diseases. Colonization of C. albicans on the oral mucosa and tooth enamel surfaces is established via the interaction between C.

Association of remaining tooth number with postoperative respiratory complications in heart valve surgery patients.

Objectives: This study examined the association between the number of remaining teeth and the incidence of postoperative respiratory complications in patients undergoing heart valve surgery.

Methods: We retrospectively enrolled 157 patients who underwent heart valve surgery between April 2010 and March 2019. Data on patient characteristics including systemic and oral conditions were extracted and postoperative respiratory complications were set as outcomes.

A novel mannose-containing sialoprotein adhesin involved in the binding of Candida albicans cells to DMBT1.

Candida albicans colonizes the oral cavity and causes oral candidiasis and early childhood caries synergistically with cariogenic Streptococcus mutans. Colonization of oral tissues with C. albicans is an essential step in the initiation of these infectious diseases.

Wild geckos considered as the natural reservoir of Salmonella Weltevreden in Southeast Asian countries.

A total of 1,318 wild geckos were collected in Cambodia, Thailand and Vietnam (Hue and the Mekong Delta) from 2012 to 2015 to determine the prevalence of Salmonella Weltevreden. Those geckos belong to three species: common house gecko (Hemidactylus frenatus), flat-tailed house gecko (Hemidactylus platyurus) and four-clawed gecko (Gehyra mutilata). Of 1,318 gecko samples, 293 (22.

Pathogenic mechanisms of cariogenic Propionibacterium acidifaciens.

Objective: Dental caries is one of the most common infectious diseases in humans. Older adults retain more teeth than did earlier generations and thus are at high risk of root caries. The root surface is covered by cementum, which facilitates the spread of caries lesions into dentinal tissues.

DMBT1 involvement in the human aortic endothelial cell response to Streptococcus mutans.

Streptococcus mutans is a causative organism of dental caries and has been reported to be associated with the development of cardiovascular disease (CVD). Previous studies have demonstrated that S. mutans invades human aortic endothelial cells (HAECs) and HAECs invaded by S.

Impact of a 7-Day Field Training on Oral Health Condition in Japan Ground Self-Defense Force Personnel.

Introduction: In the Japan Ground Self-Defense Force (JGSDF), personnel periodically perform intensive training that mimics the conditions seen in battle and during natural disasters. Military training involves intensive, stressful conditions, and changes in immune responses have been found in personnel following training. Good oral condition is important for military personnel to fulfill their duties; however, they have difficulty performing daily oral care under training conditions.

Experimental infective endocarditis induced by human supragingival dental plaque in rats.

Human dental plaque is thought to contribute to disease, not only in the oral cavity but also at other body sites. To investigate the pathogenicity of dental plaque in tissues remote from the mouth, we examined the ability of human supragingival dental plaque to induce infective endocarditis (IE) in rats. In total, 15 out of 27 catheterized rats survived after intravenous injections with human supragingival dental plaque suspensions containing 3 x 10(6) colony-forming units (CFU) of bacterial cells.

Experimental abscess formation caused by human dental plaque.

Human dental plaque consists of a wide variety of microorganisms, some of which are believed to cause systemic infections, including abscesses, at various sites in the body. To confirm this hypothesis experimentally, we examined the abscess-forming ability of native dental plaque in mice, the microbial features of the infectious locus produced by the plaque, and the anti-phagocytic property of microbial isolates. Aliquots of a suspension of supragingival dental plaque containing 6 x 10(6) colony-forming unit of bacteria were injected subcutaneously into the dorsa of mice.
