Calorie Restriction Effects on Aging, Learning Performance, and Transcription in Aged Aplysia californica. [PDF]
Genes Brain BehavBuccal ganglia inter‐ and motoneuronal transcriptional changes were investigated after learning food is inedible (LFI) in Aplysia californica reared on different diets at two ages. Those reared on calorie restriction showed delayed signs of aging and maintained their performance in LFI when aged while those reared on ad‐lib did not. ABSTRACT Along with

Epiafzelechin, a Flavanol, Regulates Lipid Homeostasis Through Modulation of HMGCR, PCSK9, and PPAR-α: Mechanistic Insights and Therapeutic Implications. [PDF]
Cardiovasc TherHyperlipidemia remains a leading modifiable risk factor for cardiovascular morbidity and mortality. Statins are considered the cornerstone of treatment; however, their adverse effects and limited efficacy in certain patient populations necessitate exploration of novel therapeutic avenues. Epiafzelechin (EZN), a flavanol with established antioxidant and
