Objectives: The skin is a dynamic, visible organ, showing the most obvious signs of aging. The mechanisms of extrinsic aging, most of them presented in this paper, are currently well known and also the only ones that can be counteracted. Therefore, the transition of this knowledge in the general population is of the most importance, in order to introduce healthy aging strategies, to prevent the development of chronic or malignant diseases and psychological burden related to old age.
Materials And Methods: A thorough review of the literature has been performed in order to identify the main factors involved in skin health and aging.
Outcomes: This concept article represents a compilation of seven anti-ageing directions regarding major factors involved in health, aging and beauty, respectively sun, sugar, smoking, skin care, stress, sleep and second (the passage of time), easy to comprehend by the general public but sustained by a strong scientific documentation.
Conclusions: Despite its final destination, every quality concept has to pass through academic purgatory as, once accepted, it comes to respond to ever more educated society's demands in terms of anti-ageing.

Background: Alzheimer's disease (AD) is the most prevalent cause of dementia accounting for an estimated 60% to 80% of cases. Despite advances in the research field, developing truly effective therapies for AD symptoms remains a major challenge. Sweet almond contain nutrients that have the potential of combating age-related brain dysfunction, by improving learning, memory and neurocognitive performance.

Dihydroxytrimethoxyflavone, a natural flavone found in herbal drugs, is documented to be neuroprotective in different model systems. Nevertheless, possible memory improvement effects of dihydroxytrimethoxyflavone via nuclear factor-E2-related factor 2 (Nrf2) (a crucial regulator of antioxidative system) has not been systematically evaluated.

The recent positive phase 3 clinical trials of new treatments and their licensing and roll-out in the US and other countries represents a major turning point in Alzheimer's disease research. As has been the case with many other diseases, e.g.

Background: Global epidemiological studies involving over nine million participants have shown a 35% lower incidence of Alzheimer's Disease (AD) in older cancer survivors compared to those without a history of cancer. This inverse relationship, consistent across recent studies with methodological controls, suggests that cancer itself, rather than cancer treatments, may offer protective factors against AD. This insight opens avenues for novel therapeutic strategies targeting early AD by harnessing cancer-associated protective factors.
View Article and Find Full Text PDFAlzheimer's disease pathophysiology is believed to involve various abnormalities, including those of amyloid beta (Ab) peptide and tau processing, inflammation, oxidative stress, and vascular risk factors. Aβ peptides exist in a dynamic continuum of conformational states from monomeric Aβ, to soluble progressively larger Aβ assemblies that include a range of low molecular weight oligomers to higher molecular weight protofibrils, and finally to insoluble fibrils (plaques). Various lines of evidence support the "amyloid hypothesis" that Aβ plays a central role in the pathogenesis of AD, and several immunotherapies have been developed to interact with this cascade in various different places which may reduce the number of soluble aggregates and insoluble Aβ fibrils deposited in the brain.
