DNA is subject to continual damage, leaving each cell with thousands of individual DNA lesions at any given moment. The efficiency of DNA repair means that most known classes of lesion have a half-life of minutes to hours, but the extent to which DNA damage can persist for longer durations remains unknown. Here, using high-resolution phylogenetic trees from 89 donors, we identified mutations arising from 818 DNA lesions that persisted across multiple cell cycles in normal human stem cells from blood, liver and bronchial epithelium.

Background: Spatial orientation is required for independent mobility in society. Deficits in spatial orientation can be an early symptom of Alzheimer's disease and other dementias, and there is a need for brief assessment tools to identify impairments.
Objective: The aim of this study was to evaluate the construct and known-group validity of our newly developed Spatial Orientation Screening (SOS) questionnaire.

Introduction: The Friedreich Ataxia Rating Scale-Activities of Daily Living (FARS-ADL) is a validated and highly utilized measure for evaluating patients with Friedreich Ataxia. While construct validity of FARS-ADL has been shown for spinocerebellar ataxia (SCA), content validity has not been established.
Methods: Individuals with SCA1 or SCA3 (n = 7) and healthcare professionals (HCPs) with SCA expertise (n = 8) participated in qualitative interviews evaluating the relevance, clarity, and clinical meaningfulness of FARS-ADL for assessment of individuals with SCA.
