Mitochondrial membrane potential probes and the proton gradient: a practical usage guide.

Abstract: Fluorescent probes for monitoring mitochondrial membrane potential are frequently used for assessing mitochondrial function, particularly in the context of cell fate determination in biological and biomedical research. However, valid interpretation of results obtained with such probes requires careful consideration of numerous controls, as well as possible effects of non-protonic charges on dye behavior. In this context, we provide an overview of some of the important technical considerations, controls, and parallel complementary assays that can be employed to help ensure appropriate interpretation of results, thus providing a practical usage guide for monitoring mitochondrial membrane potentials with cationic probes. In total, this review will help illustrate both the strengths and potential pitfalls of common mitochondrial membrane potential dyes, and highlight best-usage approaches for their efficacious application in life sciences research.

Associations of Stressors and Uplifts of Caregiving With Caregiver Burden and Depressive Mood: A Meta-Analysis

Abstract: In the present meta-analysis, we integrated findings from 228 studies on the association of six caregiving-related stressors and caregiving uplifts with burden and depressed mood. Care recipients' behavior problems showed stronger associations with caregiver outcomes than other stressors did. The size of the relationships varied by sample characteristics: Amount of care provided and care receivers' physical impairments were less strongly related to burden and depression for dementia caregivers than for caregivers of nondemented older adults. For spouse caregivers, physical impairments and care recipients' behavior problems had a stronger relationship to burden than for adult children. Furthermore, we found evidence that the association of caregiver burden with the number of caregiving tasks, perceived uplifts of caregiving, and the level of physical impairment of the care receiver were stronger in probability samples than in convenience samples.
