Upregulation of salivary α2 macroglobulin in patients with type 2 diabetes mellitus

J. K. Feng, Lu, Y. F., Li, J., Qi, Y. H., Yi, M. L., and Ma, D. Y., Upregulation of salivary α2 macroglobulin in patients with type 2 diabetes mellitus, vol. 14, pp. 2268-2274, 2015.

We investigated the expression of salivary α2-macroglobulin (α2-MG) in patients with type 2 diabetes mellitus (T2DM) to investigate its value for predicting damage to the salivary glands. A total of 116 patients with T2DM and 60 patients with impaired fasting glucose (IFG) were included in this study. Sixty health volunteers were enrolled as a control group. Unstimulated saliva was collected at 8 a.m. prior to breakfast. Expression of α2-MG was determined using an enzyme-linked immunosorbent assay.

Programmed cell death in salivary glands of Drosophila arizonae and Drosophila mulleri

P. Ianella, Azeredo-Oliveira, M. T. V., and Itoyama, M. M., Programmed cell death in salivary glands of Drosophila arizonae and Drosophila mulleri, vol. 7, pp. 476-486, 2008.

Programmed cell death (PCD) in insect metamorphosis assumes a great diversity of morphology and controlling processes that are still not well understood. With the objective of obtaining information about the PCD process, salivary glands of Drosophila arizonae and D. mulleri were studied during larval-pupal development. From the results, it can be concluded that the type of the PCD that occurs in these organs is morphologically typical of apoptosis (formation of apoptotic nuclei, followed by fragmentation into apoptotic bodies).

Acid phosphatase activity distribution in salivary glands of triatomines (Heteroptera, Reduviidae, Triatominae)

A. C. B. Anhê, Lima-Oliveira, A. P. M., and Azeredo-Oliveira, M. T. V., Acid phosphatase activity distribution in salivary glands of triatomines (Heteroptera, Reduviidae, Triatominae), vol. 6, pp. 197-205, 2007.

Acid phosphatase activity (Gömori technique) in salivary gland cells was investigated in adult insects (males and females) of four species of triatomines: Triatoma infestans, Panstrongylus megistus, Rhodnius neglectus, and Rhodnius prolixus. Binucleated cells with bulky and polyploidy nuclei were detected, with acid phosphatase activity in the heterochromatin and nucleolus, which showed the most intense response.
