Background: To investigate events possibly related to the development of D-galactose induced senescence, we examined whether 8-iso PGF(2α) formation, a marker of in vivo lipid peroxidation is altered and whether its biosynthesis is associated with 11-dehydro-TXB(2) excretion rate, as a marker of in vivo platelet activation. In this setting, we also investigated the relationship between proinflammatory mediators (IL-6 and TNF-α from one, and lipid peroxidation and platelet activation, from another aspect.
Methods And Results: Forty animals were divided, depending on treatment with d-galactose into: placebo and D-galactose treated rats. 8-iso-PGF(2α), IL-6 and TNF-α were measured in plasma, while 11-dehydro-TXB(2) was determined in the urine after a six week treatment with d-galactose. Compared to placebo, d-galactose treated animals showed significantly higher levels of all measured parameters.
Conclusions: D-galactose induced changes in the rate of F(2)-isoprostane formation are associated with the changes in the excretion rate of 11-dehydro-TXB(2).

Background: Interactions between RNA-binding proteins and RNA regulate RNA transcription during osteoporosis. Ferroptosis, a programmed cell death caused by iron metabolism, plays a vital role in osteoporosis. However, the mechanisms by which RNA-binding proteins are involved in ferroptosis during osteoporosis remain unclear.

Background: Our previous studies reported that D-galactose (D-gal) administration for four to eight weeks caused metabolic disturbance, brain mitochondrial dysfunction, and brain aging, leading to cognitive dysfunction in similar with natural aging condition. Spermidine is a polyamine that can be found naturally. Spermidine has been showed the beneficial effects on various models, such as attenuating metabolic/gut impairments in obesity, and ameliorating memory loss in aged model.

Background: Various investigations have elucidated the impact of diet and environmental toxins on the aging process. Melamine (Mel) is a widely recognized and infamous food adulterant with documented toxicity in various organs, including the brain. Nevertheless, there is currently a dearth of reports on the neurotoxic effects of Mel in aging neurons.
