Effects of oxygen concentration during incubation and broiler breeder age on embryonic heat production, chicken development, and 7-day performance

open access: yesAnimal, 2021
Older breeder flocks produce eggs with a relatively larger yolk and thereby a higher nutrient availability than young breeder flocks. To optimise nutrient utilisation and embryonic development throughout incubation and posthatch period, embryos ...

Interaction between eggshell temperature and carbon dioxide concentration after day 8 of incubation on broiler chicken embryo development

open access: yesAnimal, 2021
Carbon dioxide (CO2) is considered to be an important factor during incubation of eggs. Effects attributed to higher CO2 concentrations during experiment might be due to confounding effects of other environmental conditions, such as incubation ...

Evaluation of Antimicrobial Activity and Cytotoxicity of an Epoxy Resin-Based Endodontic Sealer Containing Nanoparticles Amorphous Calcium Phosphate

open access: yesInternational Journal of Dentistry, 2023
Background. The main cause of posttreatment disease in endodontics is the remaining of microorganisms within the root canal walls after endodontic therapy. Therefore, it is essential to use root canal sealers with potent antibacterial properties.
