PURPOSE Curcumin is known to exert numerous biological effects including anti-inflammatory activity. In this study, we investigated the effects of curcumin on the production of interleukin-6 (IL-6) by murine macrophage-like RAW 264.7 cells stimulated with lipopolysaccharide (LPS) from Prevotella intermedia, a major cause of inflammatory periodontal disease, and sought to determine the underlyin...

PURPOSE The present study was undertaken to determine the presence of 3 periodontopathic bacteria in the supragingival plaques of 3- to 16-year-old children with different oral health conditions. METHODS DMFT and dft, PMA index (P=papillary gingivitis, M=marginal gingivitis, and A=attached gingivitis), OHI (oral hygiene index), and oral malodor of each subject were determined prior to the col...

Two experiments were conducted to study the effects of increased atmospheric nitrogen deposition and elevated CO2 on investment in carnivory by two sundew species, Drosera rotundifolia and D. intermedia. A field study was conducted with D. rotundifolia at Inverness Mud Lake Bog in Inverness Twp., MI where plants were exposed to simulated future increases in atmospheric nitrogen deposition predi...

The present article deals with morphological comparison of four species of shrimp larvae, such as Neocrangon communis and Mesocrangon intermedia, Crangon dalli and C. septemspinosa, inhabiting the Okhotsk Sea and north-western part of the Pacific Ocean. Morphological comparison of I-V zoeal stages is discussed. The main morphological differences of the appropriate larval stages are detected. Mo...

BACKGROUND In a semi-arid ecosystem, water is one of the most important factors that affect vegetation dynamics, such as shrub plantation. A water use strategy, including the main water source that a plant species utilizes and water use efficiency (WUE), plays an important role in plant survival and growth. The water use strategy of a shrub is one of the key factors in the evaluation of stabili...

BACKGROUND In previous works we have shown that a low-molecular-mass (LMM) fraction from mushroom (Lentinus edodes) homogenate interferes with binding of Streptococcus mutans to hydroxyapatite and Prevotella intermedia to gingival cells. Additionally, inhibition of biofilm formation of both odonto- and periodonto-pathogenic bacteria and detachment from preformed biofilms have been described for...

OBJECTIVE This study describes subgingival bacterial profiles associated with clinical periodontal status in Ghanaian adolescents with or without progression of attachment loss. MATERIALS AND METHODS Among 500 adolescents included in a cohort study, 397 returned 2 years later for a periodontal re-examination, including full-mouth CAL measurements. At follow-up, a subgroup of 98 adolescents wa...

PURPOSE Elderly people are thought to be more susceptible to periodontal disease due to reduced immune function associated with aging. However, little information is available on the nature of immune responses against putative periodontal pathogens in geriatric patients. The purpose of this study was to evaluate the serum IgG antibody responses to six periodontal pathogens in geriatric subjects...

The aims of this study were to use multilocus sequence typing (MLST) to (i) investigate the population structure, diversity and molecular epidemiology of the weakly haemolytic anaerobic intestinal spirochaete Brachyspira intermedia, and (ii) determine the relationship of the species to the other two indole-positive but strongly haemolytic Brachyspira species--B. hyodysenteriae and "B. suanatina...
