To clarify appropriateness of current claims for health and wellness virtues of argan oil, studies were conducted in inflammatory states. LPS induces inflammation with reduction of PGC1- α signaling and energy metabolism. Argan oil protected the liver against LPS toxicity and interestingly enough preservation of peroxisomal acyl-CoA oxidase type 1 (ACOX1) activity against depression by LPS. This model of LPS-driven toxicity circumvented by argan oil along with a key anti-inflammatory role attributed to ACOX1 has been here transposed to model aging...

REVIEW

Organ shortage has long been an obstacle to transplant procedures. As acceptance of aging kidneys from expanded criteria donors increases, the long-term outcomes of renal allografts could be unsatisfactory. The klotho gene, which is known as an antiaging gene that is highly expressed in kidneys, is closely associated with chronic kidney disease and acute kidney injury. Results from existing literature have shown a tendency to support Klotho as a renal protective protein owing to its pleiotropic effects. However, few data are available on Klotho in renal transplant...

Gengnianchun (GNC), a traditional Chinese medicine (TCM), is believed to have beneficial effects on ageing-related diseases, such as antioxidant properties and effects against A β -induced toxicity. We previously found that GNC extended the lifespan of Caenorhabditis elegans . However, the mechanism underlying this effect was unclear. In this study, we further explored the mechanisms of GNC using a C. elegans model. GNC significantly increased the lifespan of C. elegans and enhanced oxidative and thermal stress resistance...

DNA methylation (DNAm) clocks such as the Horvath DNAm clock provide the most accurate biological determination of biological age relative to chronological age available today. However, there is little correlation between DNAm clocks, telomere-based aging clocks, and transcriptomic-based aging clocks. Recently, a genome-wide association study identified single-nucleotide polymorphism variants of TERT, the gene that encodes telomerase, as accelerating intrinsic aging in the Horvath DNAm clock. These same variants have been previously associated with long telomeres in leukocytes, suggesting that TERT acts paradoxically on telomere-associated aging and DNAm-associated aging...

BACKGROUND: Mature skin is characterized by a loss of elasticity, hyperpigmentation, and dehydration. L-ascorbic acid stimulates the synthesis of collagen type I, inhibits melanogenesis, and helps to maintain correct skin hydration. Combining microneedle mesotherapy with the application of preparations rich in vitamin C results in better therapeutic effects due to the improved absorption of active substances. The study evaluates the effectiveness of the application of strawberry hydrolysate enriched with L-ascorbic acid using microneedle mesotherapy...

The " long-life elixir " has long represented for humans a dream, a vanity's sin for remaining young and to long survive. Today, because of ageing population phenomenon , the research of antiageing interventions appears to be more important than ever, for preserving health in old age and retarding/or delaying the onset of age-related diseases. A hope is given by experimental data, which evidence the possibility of retarding ageing in animal models. In addition, it has been also demonstrated in animal life-extending studies not only the possibility of increasing longevity but also the ability to retard the onset of age-related diseases...

Current antiaging strategies focusing on druggable targets have met with relatively limited success to date. Replacement of cells, tissues, and organs could provide an alternative means for targeting age-induced damage and potentially eliminating some of it. However, before this is a viable option, numerous challenges need to be addressed. Most notably, whether the brain, which defines our self-identity, is amenable to replacement therapies is unclear. Here, we consider whether progressive cell replacement is a potential approach to reverse brain aging without grossly altering function...
