Decellularized tendon xenografts offer a promising alternative for reconstruction by using ubiquitously available material. This study compares static and centrifugal seeding of avian tendon scaffolds with NIH 3T3 fibroblasts. Incorporation of viable cells was achievable with both techniques, represented by DNA content. Proliferation rate and viability assay showed neither damage by centrifugal force nor superiority of the technique. Cell proliferation after 10 days of culture demonstrated that the scaffold did not hinder 3-D culturing. Confocal laser microscopy revealed structural details as formation of focal adhesions, to provide deeper insight into the process of cell attachment and growth in xenografts.

Fennel seed (Foeniculum vulgare Mill.) essential oil (FEO), which is rich in the phytoestrogenic compound trans-anethole, interacts with oestrogen receptors and influences molecular targets within cells and hormonal responses. This study examined the effect of dietary encapsulated FEO inclusion levels on performance, reproductive hormone profiles, and gene expression in laying hens during the early and late phases.

Zearalenone (ZEN), a prevalent mycotoxin found in cereal crops, poses a significant threat to food safety and human health. To address this issue, there is an urgent need for rapid, sensitive, and cost-effective detection methods. In this study, we developed a novel bimodal aptasensor based on NH-UiO-66@MB composites for ZEN detection.

Feeding mallards is a popular activity worldwide. Bread, which is most commonly fed, is relatively high in carbohydrates and salt and low in calcium and phosphorus, posing potential risks to the duck's health. Because the impact of a feeding ban is often minimal, it is preferable to identify healthier alternatives for feeding the mallards.
