Teeth caries is one of predominant civilization diseases. Dental fillings with antimicrobial addition might allow prevention of secondary caries. The purpose of this study was to evaluate hardness and tensile strength of cetylpyridinium chloride modified water activated glass-ionomer cement. |
METHODS |
Samples with diameter of 6 mm and height of 3 mm made of water-activated glass-ionomer cement were control group (0.0%). Test groups were series of samples of the same dimensions, with addition of cetylpyridinium chloride antimicrobial in concentrations of 0.5, 1.0, 1.5 and 2.0%. Two subgroups were prepared in each gro... |
RESULTS |
During hardness studies, no strong effect of antimicrobial concentration on hardness of samples was observed. Higher hardness values after 24 hours were demonstrated for all groups, compared to the samples tested after 1 hour. The exception was the group with the addition of 1% cetylpyridinium chloride, in which no sta... |
CONCLUSIONS |
There was no significant effect of cetylpyridinium chloride concentration on the hardness of the samples that significantly increased during the study. With the increase in antimicrobial concentration a decrease in diametral tensile strength value was observed, but these values did not change over time.Educating human ... |

A 78-year-old woman with rheumatoid arthritis and a massive rotator cuff tear of the right shoulder was treated with reverse shoulder arthroplasty, but a pseudoaneurysm in the posterior humeral circumflex artery suddenly ruptured 7 months after surgery. Embolization of the pseudoaneurysm and skin treatment successfully... |
CONCLUSION |
Although a rare occurrence, vascular complication can occur after shoulder arthroplasty. The cause of the pseudoaneurysm was hypothesized to be repetitive contact between the humeral component and the artery and/or chronic traction of the blood vessel because of its chronic onset.Strategic Social Learning and the Popul... |
Human culture is widely believed to undergo evolution, via mechanisms rooted in the nature of human cognition. A number of theories predict the kinds of human learning strategies, as well as the population dynamics that result from their action. There is little work, however, that quantitatively examines the evidence f... |
The chronology of the Aegean Late Bronze Age is a vigorously contested area of archaeological study, with "high" and "low" schemes emerging over the last three decades. The chronological lynchpin for this period is the catastrophic eruption of Thera (Santorini), at a point in the mature Late Minoan (LM) I A ceramic per... |

In this chapter two phases of the origins and development of the concept of person in ancient Rome are discussed. In a prephilosophical phase, the origins of the word can be traced back to the Etruscans and the Greeks, respectively. The Latin word persona is most likely of Etruscan origin. At first the Romans used this... |
Abstract This article aims to build a bridge between two areas of philosophical research: the structure of kinds and metaphysical modality. Our central thesis is that kinds typically involve super-explanatory properties, and that these properties are therefore metaphysically essential to natural kinds. Philosophers of ... |
• What is computational linguistics? NL and the computer representation of knowledge. Levels of representation. • What is parsing? A definition, and difficulty of parsing.

OBJECTIVE |
To examine associations between type 2 diabetes and fiber, glycemic load (GL), dietary glycemic index (GI), and fiber-rich foods. |
RESEARCH DESIGN AND METHODS |
This was a prospective study of 36,787 men and women aged 40-69 years without diabetes. For all self-reported cases of diabetes at 4-year follow-up, confirmation of diagnosis was sought from medical practitioners. Case subjects were those who reported diabetes at follow-up and for whom there was no evidence that they d... |
RESULTS |
Follow-up was completed by 31,641 (86%) participants, and 365 cases were identified. The odds ratio (OR) for the highest quartile of white bread intake compared with the lowest was 1.37 (95% CI 1.04-1.81; P for trend = 0.001). Intakes of carbohydrate (OR per 200 g/day 0.58, 0.36-0.95), sugars (OR per 100 g/day 0.61, 0.... |
CONCLUSIONS |
Reducing dietary GI while maintaining a high carbohydrate intake may reduce the risk of type 2 diabetes. One way to achieve this would be to substitute white bread with low-GI breads.Gallbladder mucosal function: studies in absorption and secretion in humans and in dog gallbladder epithelium. |
