Relationships Between Test Results for Oral Hypofunction, Subjective Frailty Symptoms and Oral Health-Related Quality of Life of Japanese Dental Outpatients: A Multicentre, Cross-Sectional Study.

Background: Oral hypofunction is the stage before oral dysfunction. The subjective symptoms of poor oral function and the decline in oral health-related quality of life (OHRQoL) that occur in the oral hypofunction stage can be missed.

Objective: This multicentre cross-sectional study was performed to examine the relationships between the test results for oral hypofunction, subjective frailty symptoms and OHRQoL of outpatients in dental clinics.

Retrospective cohort study of rough-surface titanium implants with at least 25 years' function.

Background: The longitudinal clinical outcomes over decades contribute to know potential factors leading to implant failure or complications and help in the decision of treatment alternatives.

Methods: The cases of all patients who received dental implants treated with titanium plasma-sprayed surfaces and whose prostheses were set in the period 1984-1990 at seven private practices were retrospectively analyzed. The cumulative survival rate, the cumulative incidence of peri-implantitis, and the complication-free prosthesis rate were calculated with Kaplan-Meier survival curves, and the factors' influence on implant survival rate and the incidence of peri-implantitis were determined by a single factor in univariate analyses and multivariate analyses.

Structural and functional differences in two cyclic bacteriocins with the same sequences produced by lactobacilli.

Lactobacillus gasseri LA39 and L. reuteri LA6 isolated from feces of the same human infant were found to produce similar cyclic bacteriocins (named gassericin A and reutericin 6, respectively) that cannot be distinguished by molecular weights or primary amino acid sequences. However, reutericin 6 has a narrower spectrum than gassericin A.

Immunostimulatory oligonucleotide, CpG-like motif exists in Lactobacillus delbrueckii ssp. bulgaricus NIAI B6.

The present study was conducted to find an immunostimulatory oligonucleotide derived from yogurt starter cultures. The chromosomal DNA was purified from nine strains of Lactobacillus delbrueckii ssp. bulgaricus and six strains of Streptococcus thermophilus.

A novel immunostimulating aspect of Lactobacillus gasseri: induction of "Gasserokine" as chemoattractants for macrophages.

The chemotactic activity of the culture supernatants from 14 strains of Lactobacillus acidophilus and L. gasseri was examined for murine macrophages. Significant macrophage chemotactic activity was observed in three strains of L.
