The emergence of mRNA vaccines offers great promise and a potent platform in combating various diseases, notably COVID-19. Nevertheless, challenges such as inherent instability and potential side effects of current delivery systems underscore the critical need for the advancement of stable, safe, and efficacious mRNA vaccines. In this study, a robust mRNA vaccine (cmRNA-1130) eliciting potent immune activation has been developed from a biodegradable lipid with eight ester bonds in the branched tail (AX4) and synthetic circular mRNA (cmRNA) encoding the trimeric Delta receptor binding domain of the SARS-CoV-2 spike protein.

Background: Emerging research underscores the significance of midlife obesity, defined by a BMI of 30 kg/m or higher in persons age 40-60 years, as a risk factor for Alzheimer's disease (AD) in later life. Due to the various properties of each body component, it is important to characterize the neurodegenerative effects of fat within the muscle, known as a predictor of metabolic health and cognition. We investigated the relationships between thigh total fat-to-muscle ratio (FMR) and brain cortical thickness in cognitively normal midlife individuals.

Cutaneous manifestations of multiple myeloma are rare but, as with other extramedullary manifestations, carry a worse prognosis. We present the case of a 65-year-old man with immunoglobulin G κ multiple myeloma and prior autologous stem cell transplant. On subsequent therapy, he presented with multiple new cutaneous and subcutaneous left hip masses.

Ebola virus (EBOV) causes severe disease in humans, with mortality as high as 90%. The small-molecule antiviral drug remdesivir (RDV) has demonstrated a survival benefit in EBOV-exposed rhesus macaques. Here, we characterize the efficacy of multiple intravenous RDV dosing regimens on survival of rhesus macaques 42 days after intramuscular EBOV exposure.
