The aim of this study was to investigate the impact of early colonizing species on the structure and the composition of the bacterial community developing in a subgingival 10-species biofilm model system. The model included Streptococcus oralis, Streptococcus anginosus, Actinomycesoris, Fusobacterium nucleatum subsp. nucleatum, Veillonella dispar, Campylobacter rectus, Prevotella intermedia, Po...

Beta-thalassaemia is a hereditary defect in the synthesis of beta-polypeptide chains of haemoglobin. Most patients with beta-thalassaemia can be classified, both genetically and haematologically, into those with the homozygous form of the disease, and those with the heterozygous disease or thalassaemia minor. However, in clinical practice one occasionally encounters a patient with thalassaemia ...

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...

Background: In this article, it was analyzed how snow melting affects the assembly of lichen and moss communities in a small area of the coastal region of Barton Peninsula, which is in maritime Antarctic. In the small area, even though there is a huge gap of difference of the environment between the snow-filled area and snow-melt one, the latter did not have distinctive environmental gradients....

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...
