Alzheimer's disease and related dementias are a leading cause of morbidity in our aging populations. Although influenced by genetic factors, fewer than 5% of Alzheimer's disease and related dementia cases are due solely to genetic causes. There is growing scientific consensus that these dementias arise from complex gene by environment interactions.

This study explores the therapeutic potential of targeting fatty acid amide hydrolase (FAAH), the major enzyme degrading AEA, in mouse models of amyloidosis (APP/PS1 and Tg2576). Enhancing AEA signaling by genetic deletion of FAAH delayed cognitive deficits in APP/PS1 mice and improved cognitive symptoms in 12-month-old AD-like mice.

Due to the continuous exposure to bisphenol-A (BPA), the current study was conducted to evaluate taurine's neuroprotective action against BPA's adverse effect on the brain. Rats were grouped into control, BPA-treated rats, and taurine + BPA-treated rats. At the end of the 35-day treatment period, the memory of the rats was evaluated using the novel object test and the Y-maze test.

Age- and sex-specific differences in myocardial sympathetic tone and left ventricular remodeling following myocardial injury.
Biol Sex Differ
January 2025
Department of Nuclear Medicine, University Hospital Zurich, Zurich, CH-8091, Switzerland.
Background: Presentations and outcomes of acute myocardial infarction (MI) differ between women and men, with the worst outcomes being reported in younger women. Mental stress induced ischemia and sympathetic activation have been suggested to play a prominent role in the pathogenesis of MI in younger women, however, the impact of sex hormones on these parameters remains unknown.
Methods: The effect of sex hormones and age on myocardial infarct size and myocardial sympathetic activity (MSA) was assessed in male and female, as well as young (4-6 months) and aged (20-22 months) FVB/N mice (n = 106, 60 gonadectomized and 46 sham-operated animals) who underwent in vivo [C]meta-hydroxyephedrine ([C]mHED) positron emission tomography (PET) and cardiac magnetic resonance (CMR) imaging 24 h after a 30 min myocardial ischemic injury.
