Nucleic Acid Specificity, Cellular Localization and Reduced Toxicities of Thiazole Orange-Neomycin Conjugates.

Selective binding of small molecule ligands to nucleic acids with high affinity and limited toxicity remains an important goal in the development of compounds that can probe DNA or RNA in cells. Thiazole orange is a cell semi-permeant, fluorescent cyanine dye, with low background noise, that binds several forms of nucleic acids. However, thiazole orange can exhibit cytotoxicity when used at high concentration and/or with prolonged exposure.

Derivation and Validation of an Electronic Health Record Penicillin Allergy De-Labeling Prevalence Measure.

With no standard method to capture penicillin allergy de-labeling prevalence across populations, we developed and validated a simple penicillin allergy de-labeling prevalence measure from electronic health records that achieved perfect sensitivity (100.0%), high specificity (99.4%), and strong agreement with a comprehensive algorithm that included free-text manual review (Kappa=0.

Effects of a physical activity intervention on perceived stress, fatigue, and depressive symptoms in older adults: A secondary analysis of the LIFE Study.

Background: Engaging in physical activity is critical for maintaining well-being in older adults, particularly those at heightened risk for mobility disability. We assessed the effects of a physical activity (PA) intervention on perceived stress, fatigue, and depressive symptoms compared to a health education (HE) program in older adults with mobility challenges and evaluated differential effects of the interventions among those with the poorest self-rated mental health at baseline.

Methods: Secondary data analysis of the Lifestyle Interventions and Independence for Elders (LIFE) Study, a single-blinded, parallel randomized controlled trial conducted between February 2010 and December 2013.

ISLAND Campus: a fee-free formal university educational intervention in mid- to later-life to reduce modifiable risk factors for dementia and improve cognition.

Introduction: Previous research has tended to focus on early-life education for dementia risk reduction, yet there are great gains for building cognitive reserve in mid- to later-life through educational interventions. ISLAND (Island Study Linking Ageing and Neurodegenerative Disease) Campus offered free university study to all ISLAND participants, with flexible in-person/online learning models to remove educational, socioeconomic and geographical barriers. Here the core hypothesis of ISLAND Campus was investigated: that engagement in later life education leads to improvements in modifiable risk factors for dementia, cognition and blood-based biomarkers.
