Relationship between elastase and total antioxidant status in young subjects with recent myocardial infarction
2008
In a group of young subjects with acute myocardial infarction (AMI) (68 men and 7 women; mean age 39.6 ± 5.7 years) we examined the plasma concentration of elastase, the thiobarbituric acid-reactive substances (TBARS) and the total antioxidant status (TAS) at the initial stage of AMI. In this group we found an increase of elastase (p <0.001) and TBARS (p < 0.001) and a decrease of TAS (p < 0.001). A statistical correlation was observed in the whole group of AMI patients between plasma elastase and TAS (p < 0.01) and this correlation was more statistically significant in patients with more risk factors and not in those with more involved vessels.
The relationship between pulp calcifications and salivary gland calcifications
2014
Aim: Pulp stones are discrete calcified bodies found in the dental pulp. Sialolithasis is the most common salivary gland disease. The aim of the present study was to determine the relationship between the pulp stones and salivary gland stones. Material and Methods: 196 patients were randomly selected from the out patient department for the study. The periapical radiographs for all patients were evaluated for the presence or absence of the narrowing of dental pulp chambers and pulp canals. The intra oral occlusal radiographs were also evaluated to determine the presence or absence of salivary stones. The results were compared and analyzed using the Chi-square test ( p 0.001) and also between…
Is there any scaling in the cluster distribution?
1994
We apply fractal analysis methods to investigate the scaling properties in the Abell and ACO catalogs of rich galaxy clusters. We also discuss different technical aspects of the method when applied to data sets with small number of points as the cluster catalogs. Results are compared with simulations based on the Zel'dovich approximation. We limit our analysis to scales less than 100 $\hm$. The cluster distribution show a scale invariant multifractal behavior in a limited scale range. For the Abell catalog this range is 15--60$\hm$, while for the ACO sample it extends to smaller scales. Despite this difference in the extension of the scale--range where scale--invariant clustering takes plac…
