Lead acetate uptake in the nasal septum during midfacial growth in Macaca fascicularis

American Journal of Orthodontics
K Moin, P K YEN


Growth of the bone structures of the nasal septum was studied in two young Macaca fascicularis (human age, 8 to 9 years) that received serial injections of lead acetate as a maker. The nasal septum in these monkeys is a thin, fragile, but morphologically complex, structure. A number of adjustment sites to the lengthening of the midface were observed, namely, at the cranial surface, at the junction of the bulbous perpendicular plate of the vomer and the nasal septum, and at the inferior junction of the vomer and palate. No apparent growth site was present at the interface of the septal cartilage with the vomer. Results suggest that the nasal septum in Macaca fascicularis adapts to growth changes in the midface.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.
