Ángel Gil, Julio Plaza-Diaz, María Dolores Mesa
BACKGROUND: Classically, vitamin D has been implicated in bone health by promoting calcium absorption in the gut and maintenance of serum calcium and phosphate concentrations, as well as by its action on bone growth and reorganization through the action of osteoblasts and osteoclasts cells. However, in the last 2 decades, novel actions of vitamin D have been discovered. The present report summarizes both classic and novel actions of vitamin D. SUMMARY: 1,25(OH)2 vitamin D, the active metabolite of vitamin D, also known as calcitriol, regulates not only calcium and phosphate homeostasis but also cell proliferation and differentiation, and has a key a role to play in the responses of the immune and nervous systems...

Ample evidences demonstrate that cytochrome P450 epoxygenase-derived epoxyeicosatrienoic acids (EETs) exert diverse biological activities, which include potent vasodilatory, anti-inflammatory, and cardiovascular protective effects. In this study, we investigated the effects of endothelium-specific CYP2J2 overexpression on age-related insulin resistance and metabolic dysfunction. Endothelium-specific targeting of the human CYP epoxygenase, CYP2J2, transgenic mice (Tie2-CYP2J2-Tr mice) was utilized. The effects of endothelium-specific CYP2J2 overexpression on aging-associated obesity, inflammation, and peripheral insulin resistance were evaluated by assessing metabolic parameters in young (3 months old) and aged (16 months old) adult male Tie2-CYP2J2-Tr mice...

BACKGROUND: Aging is associated with some cognitive decline and enhanced risk of development of neurodegenerative diseases. It is assumed that altered metabolism and functions of neurotrophin systems may underlie these age-related functional and structural modifications. CerebrolysinTM (CBL) is a neuropeptide mixture with neurotrophic effects, which is widely used for the treatment of stroke and traumatic brain injury patients. It is also evident that CBL has an overall beneficial effect and a favorable benefit-risk ratio in patients with dementia...

The increase in the elderly population has generated concern to meet health demands. The research efforts to elucidate the mechanisms of damage associated with aging have also been significantly increased, especially in order to avoid the reduction of the cognitive abilities in geriatric patients, resulting from the damage generated mainly at the level of the hippocampus during old age. At present, many studies describe resveratrol as an antiaging component. There are reports that it can activate the Sirt1 gene related to antiaging, emulating the effects obtained by caloric restriction in rodents...

Zoe Diana Draelos
The male cosmeceutical market is still underdeveloped. Although women embrace skin care as a part of general health, this concept has not gained wide male acceptance. Shaving is probably the most beneficial daily grooming event men commonly undertake for skin appearance and may account for the failure of antiaging cosmeceuticals to attract attention in this segment. In addition, there are many physiologic differences between male and female skin, with less of a need for moisturization and photoprotection in men...

Increasing numbers of men are seeking aesthetic treatments for fat reduction, skin rejuvenation, and other antiaging goals. Compared with women, however, men have distinctly different anatomy and physiologic differences that manifest in the aging process. Given that both anatomy and the aging process affect treatment strategies and clinical outcomes, there is a need for dermatologists to be acutely aware of these male-specific nuances to provide the best clinical care and patient satisfaction.
