Promising Effects of Novel Supplement Formulas in Preventing Skin Aging in 3D Human Keratinocytes.

Dietary intervention is considered a safe preventive strategy to slow down aging. This study aimed to evaluate the protective effects of a commercially available supplement and six simpler formulations against DNA damage in 3D human keratinocytes. The ingredients used are well known and were combined into various formulations to test their potential anti-aging properties.

The Use of Microbial Modifying Therapies to Prevent Psoriasis Exacerbation and Associated Cardiovascular Comorbidity.

Psoriasis has emerged as a systemic disease characterized by skin and joint manifestations as well as systemic inflammation and cardiovascular comorbidities. Many progresses have been made in the comprehension of the immunological mechanisms involved in the exacerbation of psoriatic plaques, and initial studies have investigated the mechanisms that lead to extracutaneous disease manifestations, including endothelial disfunction and cardiovascular disease. In the past decade, the involvement of gut dysbiosis in the development of pathologies with inflammatory and autoimmune basis has clearly emerged.

Peto's paradox: Nature has used multiple strategies to keep cancer at bay while evolving long lifespans and large body masses. A systematic review.

Comparative oncology is an understudied field of science. We are far from understanding the key mechanisms behind Peto's paradox, i.e.

The spontaneous immortalization probability of mammalian cell culture strains, as their proliferative capacity, correlates with species body mass, not longevity.

Background: The Peto's paradox consists in the observation that individuals from long-lived and large animal species do not experience a higher cancer incidence, despite being exposed for longer time to the possibility of accumulating mutations and having more target cells exposed to the phenomenon. The existence of this paradox has been recently confirmed (Vincze et al., 2022).
