Facial Growth: Does It Play A Role In Long-Term Stability Of Orthodontic Treatment?, Ib Leth Nielsen

Taiwanese Journal of Orthodontics

Following orthodontic treatment there is usually a period of retention to maintain the treatment result. This period can vary from a few years to even lifelong retention all depending upon the clinician, type of treatment and severity of the initial malocclusion. In most cases retention is planned for one to two years, but some clinicians routinely recommend continuous retention into adulthood. The retention planned for a patient is unfortunately often based on intuition rather than on scientific evidence. Furthermore, the retention is frequently not planned based on the initial malocclusion, the patient's facial growth pattern nor is attention paid to …

The ability of endothelial cells to sense and respond to dynamic changes in blood flow is critical for vascular homeostasis and cardiovascular health. The mechanical and geometric properties of the nuclear and cytoplasmic compartments affect mechanotransduction. We hypothesized that alterations to these parameters have resulting mechanosensory consequences. Using atomic force microscopy and mathematical modeling, we assessed how the nuclear and cytoplasmic compartment stiffnesses modulate shear stress transfer to the nucleus within aging endothelial cells. Our computational studies revealed that the critical parameter controlling shear transfer is not the individual mechanics of these compartments, but the stiffness ratio between them. Replicatively …

Il-34 Exacerbates Pathogenic Features Of Alzheimer's Disease And Calvaria Osteolysis In Triple Transgenic (3x-Tg) Female Mice., Anny Ho, Bidii Ngala, Chiaki Yamada, Christopher Garcia, Carolina Duarte, Juliet Akkaoui, Dumitru Ciolac, Amilia Nusbaum, William Kochen, Daniela Efremova, Stanislav Groppa, Lubov Nathanson, Stephanie Bissel, Adrian Oblak, Melissa A. Kacena, Alexandru Movila

HPD Articles

Hallmark features of Alzheimer's disease (AD) include elevated accumulation of aggregated Aβ40 and Aβ42 peptides, hyperphosphorylated Tau (p-Tau), and neuroinflammation. Emerging evidence indicated that interleukin-34 (IL-34) contributes to AD and inflammatory osteolysis via the colony-stimulating factor-1 receptor (CSF-1r). In addition, CSF-1r is also activated by macrophage colony-stimulating factor-1 (M-CSF). While the role of M-CSF in bone physiology and pathology is well addressed, it remains controversial whether IL-34-mediated signaling promotes osteolysis, neurodegeneration, and neuroinflammation in relation to AD. In this study, we injected 3x-Tg mice with mouse recombinant IL-34 protein over the calvaria bone every other day for 42 days. Then, …

Candida-Induced Granulocytic Myeloid-Derived Suppressor Cells Are Protective Against Polymicrobial Sepsis, Shannon Esher Righi, Amanda J. Harriett, Elizabeth A. Lilly, Paul L. Fidel Jr., Mairi C. Noverr

School of Dentistry Faculty Publications

Polymicrobial intra-abdominal infections (IAI) can lead to life-threatening sepsis with significant morbidity and mortality, especially when pathogenic fungi are involved. We have employed an established clinically relevant mouse model of fungal/bacterial IAI and shown that immunization with low-virulence Candida species, that is, Candida dubliniensis, can induce responses that protect against sepsis via the suppression of lethal inflammation. This protection is dependent on long-lived Gr-1(+) polymorphonuclear leukocytes that display characteristics consistent with myeloid-derived suppressor cells (MDSCs) and trained innate immunity. Here we aimed to functionally and phenotypically characterize these protective Gr-1(+) leukocytes. Compared to nonimmunized control mice, we observed increased levels …
