Opis:
Anisakis simplex stage 3 larvae found in herring were used to experimentally infect 155 sticklebacks and 6 nine-spined sticklebacks, caught in the Gdynia marina (Gulf of Gdańsk). The larvae were observed in the fish body cavity as early as 24 h after infection, only the sticklebacks being affected. Altogether, 50 live and 2 dead larvae were found in the stickleback body cavity. The infection prevalence and mean intensity were 13.6% and 2.4 larvae, respectively, from 1 to 8 larvae per fish being recorded. It is concluded that the stickleback may serve as a paratenic host for Anisakis simplex.

Opis:
In this study, the trabecular bone was treated as a composite material that consists of a bone matrix weakened by ellipsoidal pores. Under the hypothesis that all information concerning the local properties and the microarchitecture are “encrypted” in the apparent properties of a given volume element (VE) of the bone, a method of retrieving these data was proposed. Software based on a genetic algorithm, combined with the incremental scale transition method was developed to this end. To test the approach, μCT measurements of four bone samples were performed providing their real micro-architecture. Tensors of apparent properties of the samples were next computed by numerical (finite element) homogenization method for a large range of the elastic properties of trabeculae. They were considered as the fitness function for the proposed algorithm. Very good agreement was found between the obtained and target values of the apparent elastic properties of the samples and volume fraction of pores. The approach is fast and accurate enough in comparison to the finite element homogenization. As an auxiliary result it was shown that the anisotropy of apparent elastic properties is mainly related to the microarchitecture of the bone, not to the intrinsic properties of trabeculae.

Opis:
The influence of the aerosols particles on the lung function was investigated by the measurements of lung function parameters in children at secondary school located in the centre of city Wroclaw (south – west of Poland). Simultaneous daily indoor and outdoor measurements of PM1, PM2,5, PM10 have been conducted with the use of Harvard cascade impactors (MS&T Area Samplers). In the study 186 children age 13–14 yrs underwent repeated spirometry (Blue Spiro) at the same time of day, 5 times during the winter/spring (heating season) and 5 times in summer/autumn. Exposure to indoor fine particulate matter PM2,5 significantly worseness FEV1 in the lung function of secondary school children (Pearson correlation: median versus indoor PM2,5, r = -0,95; p < 0.05). Correlation of the lung function parameters with other particles PM1, PM10 measured indoor and outdoor were not statistically significant. PM2.5 measured outdoor was also not significantly correlated with lung function parameters. Considerable effort should be made to improve ambient air quality. Especially there is a need to measure and control the fine particulate matter PM2,5 in winter as it has the highest impact on lung function in children.
