Computational simulations of human aging for intervention testing
Bisdemethoxycurcumin (BDMC) is a natural curcuminoid with higher solubility and stability than curcumin, yet its potential role in lifespan and healthspan regulation remains largely unexplored. This study aimed to investigate the effects of BDMC on …
Researchers conducted an intensive year-long self-study (N=1) combining time-restricted eating, exercise, Mediterranean diet, and continuous biomarker monitoring to assess how well a healthy person's body adapts to stress. The study demonstrates new methods for tracking …
Researchers used computer simulations to map how a NAD+ analog activates SIR2, an enzyme linked to aging, by triggering a cascade of conformational changes that act like an internal relay system. They identified a previously …
The physicochemical degradation of asphalt during long-term service leads to pronounced aging, characterized by increased molecular aggregation, elevated viscosity, and degraded mechanical performance. Ultrasonic treatment has shown potential for reducing the viscosity of heavy oils …
The rising incidence of neurodegenerative disorders linked to protein fibrillation in aging populations highlights the need for efficient, low-toxicity fibrillation inhibitors. Quercetin, a natural flavonoid, shows potential in both suppressing fibrillation and disaggregating mature fibrils. …
Hepatic ischemia-reperfusion (I/R) injury complicates transplantation, resection, and shock, yet lacks effective pharmacotherapy. We evaluated Leonurine (SCM-198) as a hepatoprotective agent. Male C57BL/6 mice were pretreated with SCM-198 for 7 days, then subjected to hepatic …
This paper presents a computational model of how the brain uses predictions and prior knowledge to filter and interpret sensory information. While the model shows promise in explaining existing behavioral and brain imaging data, it's …
Researchers developed FastGxC, a computational method that finds genes whose activity changes depending on tissue or cell type context—a key mechanism in disease risk. The tool is a million times faster than existing approaches and …
Researchers created a computational model that simulates how fruit fly larvae move, navigate, and learn—combining physics-based locomotion with neural circuits and behavior. This tool could help neuroscientists test theories about how brains control behavior without …
This meta-analysis of 45 neuroimaging studies (1,273 participants) identified distinct brain regions that process rewards and task difficulty separately, then integrate them to decide whether mental effort is worth the reward. The findings clarify how …
