Optimization of the density-elasticity relationship for rabbit hindlimb bones.

The rabbit is a popular experimental model in orthopaedic biomechanics due to the presence of natural Haversian remodeling, allowing for better translational relevance to the mechanobiology of human bone over traditional rodent models. Although rabbits are often used with computational modeling approaches such as the finite element (FE) method, a validated and widely agreed upon density-elasticity relationship, which is required to make subject-specific predictions, does not exist. Therefore, the purpose of this study was to determine and validate an accurate density-elasticity relationship for rabbit hindlimb bones using mathematical optimization.

A comprehensive analysis of the tubarial glands.

The tubarial glands (TGs) are a collection of salivary glands (SGs) located within the nasopharynx, proximal to the eustachian tube. Currently, there is no quantitative characterization of the TGs. We investigated the histological architecture of the TGs and compared it with the major and minor SGs for categorization.

Quantification of an Eikelboom type 021N bulking event with fluorescence in situ hybridization and real-time PCR.

Primers targeting 16S rRNA genes were designed to detect and quantify Eikelboom type 021N organisms by real-time PCR. Eikelboom type 021N filamentous bulking was induced in a laboratory-scale sequencing batch reactor and the evolution of Eikelboom type 021N 16S rRNA and 16S rRNA genes was monitored. A significant correlation was found between the sludge volume index and the amount of these filamentous organisms present in the sludge (r (2)=94.
