A Comparison of Speech Features between Mild Cognitive Impairment and Healthy Aging Groups.

Background And Purpose: Language dysfunction is a symptom common to patients with Alzheimer's disease (AD). Speech feature analysis may be a patient-friendly screening test for early-stage AD. We aimed to investigate the speech features of amnestic mild cognitive impairment (aMCI) compared to normal controls (NCs).

Localization of ODAM, PCNA, and CK14 in regenerating junctional epithelium during orthodontic tooth movement in rats.

Objective: To identify the regenerating junctional epithelium (JE) during orthodontic tooth movement in rats.

Materials And Methods: Closed-coil springs were used to create a 20 g mesial force to the maxillary first molars. On days 1, 3, 7, 10, and 14 after force application, histologic changes in JE were examined by immunohistochemistry using proliferating cell nuclear antigen (PCNA), odontogenic ameloblast-associated protein (ODAM), and cytokeratin 14 (CK14).
