Dominant-negative mutations potentiated by the HSF1-regulated proteostasis network.

Protein mutational landscapes are sculpted by the impacts of the resulting amino acid substitutions on the protein's stability and folding or aggregation kinetics. These properties can, in turn, be modulated by the composition and activities of the cellular proteostasis network. Heat shock factor 1 (HSF1) is the master regulator of the cytosolic and nuclear proteostasis networks, dynamically tuning the expression of cytosolic and nuclear chaperones and quality control factors to meet demand.

Prognostic Index for Liver Radiation (PILiR).

A Prognostic Index for Liver Radiation (PILiR) for improved patient selection for stereotactic liver-directed radiotherapy (SBRT) was developed. Using a large single-center database, 195 patients treated with SBRT for local control, including 66 with hepatocellular carcinoma (HCC) and 129 with metastatic liver disease, were analyzed. Only patients ineligible for alternative treatments were included.

Mediators of Functional Disability at Mid- and Late-Life.

As the number and proportion of older adults living in the U.S. increases, growing evidence shows that people are entering late life with more functional disability than in previous generations.

Gene Electrotransfer via Conductivity-Clamped Electric Field Focusing Pivots Sensori-Motor DNA Therapeutics: "A Spoonful of Sugar Helps the Medicine Go Down".

Viral vectors and lipofection-based gene therapies have dispersion-dependent transduction/transfection profiles that thwart precise targeting. The study describes the development of focused close-field gene electrotransfer (GET) technology, refining spatial control of gene expression. Integration of fluidics for precise delivery of "naked" plasmid deoxyribonucleic acid (DNA) in sucrose carrier within the focused electric field enables negative biasing of near-field conductivity ("conductivity-clamping"-CC), increasing the efficiency of plasma membrane molecular translocation.

Mental Health, Self-Care, and Engagement in Care among Black Women Living with HIV.

Objectives: Due to sociostructural factors, Black women living with human immunodeficiency virus (HIV) in the United States represent the highest percentage of women with HIV and experience mental health struggles that impact health behaviors. This study examines associations between mental health, self-care, medication adherence, engagement with healthcare, HIV-related healthcare visits, and hospitalization.

Methods: One hundred and nineteen Black women living with HIV in the Southeastern United States completed measures on scheduled visits (general and HIV-related healthcare), visits attended/missed/rescheduled, mental healthcare engagement (therapy and support groups), hospital visits (emergency room and overnight stays), medication adherence, and a clinician-administered interview assessing mental health.
