Background: Copper (Cu), nickel (Ni), chromium (Cr) ion release, and surface topography change from the orthodontic wire are the initial processes of corrosion that may affect the mechanical properties of the archwire. In this study, we aim to evaluate the effect of CHX, NaF, and chitosan on the corrosion of CuNiTi wire nickel and copper ions released, surface roughness change, and archwire deflection.
Methods: Ninety samples of CuNiTi Tanzo™ archwires were divided into five groups according to their immersion solution: Artificial Saliva, CHX, NaF, CHX-NaF, and chitosan group.
Article Synopsis
- The study aimed to analyze Individualized Learning Plans (ILPs) created by pediatric subinterns to understand their learning and assessment strategies, along with the barriers and facilitators to their learning.
- Researchers examined 204 ILPs across 10 US medical schools, focusing on 850 learning objectives and grouping the findings into categories like rationale, learning strategies, and challenges.
- The results showed students were committed to self-directed learning, used a variety of creative strategies, and relied on self-reflection, while also experiencing support or obstacles from their learning environments, providing valuable insights for educators.
The non-canonical mechanism of ER stress-mediated progression of prostate cancer.
J Exp Clin Cancer Res
September 2021
Background: The development of persistent endoplasmic reticulum (ER) stress is one of the cornerstones of prostate carcinogenesis; however, the mechanism is missing. Also, alcohol is a physiological ER stress inducer, and the link between alcoholism and progression of prostate cancer (PCa) is well documented but not well characterized. According to the canonical model, the mediator of ER stress, ATF6, is cleaved sequentially in the Golgi by S1P and S2P proteases; thereafter, the genes responsible for unfolded protein response (UPR) undergo transactivation.

Its diagnosis relies on visualization of the tympanic membrane, a clinical skill acquired through a deliberate approach. Instruction in pediatric otoscopy begins in medical school.
