Dermal fillers have been in use for many years for aesthetic rejuvenation of the face. More recently, however, fillers have been increasingly used as an alternative to traditional surgical procedures for non-aesthetic indications. These indications include lagophthalmos, eyelid malpositions and orbital volume deficiency. The advantages of these filler injections are multiple: minimally invasive, repeatable, titratable and even reversible (depending on the product used). We review the current literature of functional uses of filler injections as mentioned above and evaluate the safety profile and efficacy of filler injections for this purpose...

The hematopoietic system is one of the potential targets of lead intoxication. Recognition of the lead-related deleterious outcomes promotes us to explore the potential therapeutic intervention. Here, we show that ginsenoside Rg1 (Rg1), extracted from the Chinese herb Panax ginseng, remarkably ameliorates the lead acetate-caused hematological index distortion as well as advanced hematopoietic stem cells (HSCs) aging and aging associated inflammation response. Specifically, Rg1 administration alleviated the increment of aging associated p53-p21-Rb signaling in aged HSCs induced by lead acetate...

Cytotoxic T cells are critical in controlling virus infections. However, continuous antigen stimulation and negative regulatory factors cause CD8 T cells to enter a dysfunctional state (T cell exhaustion), resulting in viral persistence. We hypothesized that the exhausted T cell state could be molecularly rejuvenated using a somatic cell reprogramming technology, which is technically able to convert any types of cells to induced pluripotent stem cells (iPSCs), to regenerate functional T cells capable of purging chronic infection...

A robust and recyclable monolithic substrate applying all-inorganic metal-oxide selective contact with nanoporous (np) Au:NiOx counter electrode is successfully demonstrated for efficient perovskite solar cells, of which the perovskite active layer is deposited in the final step for device fabrication. Through annealing of the Ni/Au bilayer, the nanoporous NiO/Au electrode is formed in virtue of interconnected Au network embedded in oxidized Ni. By optimizing the annealing parameters and tuning the mesoscopic layer thickness (mp-TiO2 and mp-Al2O3), a decent PCE of 10...

INTRODUCTION: Hyaluronic acid gel has been used for rejuvenation of the periorbital tissues since 2004. The in-office, nonsurgical procedural nature has resulted in the growing popularity of the use of fillers. The periorbital region poses unique challenges to the cosmetic surgeon. Malar edema, blue-gray dyschromia, and contour irregularities are well reported short-term complications. We present a long-term follow-up review of complications associated with periocular injection of hyaluronic acid gel fillers...

Aging results in impaired neurogenesis in the two neurogenic niches of the adult mammalian brain, the dentate gyrus of the hippocampus and the subventricular zone of the lateral ventricle. While significant work has characterized intrinsic cellular changes that contribute to this decline, it is increasingly apparent that the systemic environment also represents a critical driver of brain aging. Indeed, emerging studies utilizing the model of heterochronic parabiosis have revealed that immune-related molecular and cellular changes in the aging systemic environment negatively regulate adult neurogenesis...

BACKGROUND: Rejuvenation of the dorsal surface of the hand for various conditions, such as cutaneous dyschromia, fine wrinkling, skin laxity, visible extensor tendons, and varicosities appear vital to prevent wrist and digit flexion resulting from hiding of the aged appearance of the hand. Numerous fillers have been applied to re-contour the aging dorsal surface of the hand and the results were variable. The micro-autologous fat transplantation (MAFT) technique, proposed by Lin et al...

Budding yeast, which undergoes polarized growth during budding and mating, has been a useful model system to study cell polarization. Bud sites are selected differently in haploid and diploid yeast cells: haploid cells bud in an axial manner, while diploid cells bud in a bipolar manner. While previous studies have been focused on the molecular details of the bud site selection and polarity establishment, not much is known about how different budding patterns give rise to different functions at the population level...

Background: While CRT is an effective treatment, healthy areas surrounding irradiation sites are negatively affected. Frontal lobe functions involving attention, processing speed and inhibition control are impaired. These deficits appear months to years after CRT and impair quality-of-life. Exercise has been shown to rejuvenate the brain and aid in recovery post-injury through its effects on neurogenesis and cognition. Methods: We developed a juvenile rodent CRT model that reproduces neurocognitive deficits...

Recent epidemiologic studies evidence a dramatic increase of cardiovascular diseases, especially associated with the aging of the world population. During aging, the progressive impairment of the cardiovascular functions results from the compromised tissue abilities to protect the heart against stress. At the molecular level, in fact, a gradual weakening of the cellular processes regulating cardiovascular homeostasis occurs in aging cells. Atherosclerosis and heart failure are particularly correlated with aging-related cardiovascular senescence, that is, the inability of cells to progress in the mitotic program until completion of cytokinesis...

Aging drives the occurrence of numerous diseases, including cardiovascular disease (CVD). Recent studies indicate that blood from young mice reduces age-associated pathologies. However, the "anti-aging" factors in juvenile circulation remain poorly identified. Here, we characterize the role of the apelinergic axis in mammalian aging and identify apelin as an anti-aging factor. The expression of apelin (apln) and its receptor (aplnr) exhibits an age-dependent decline in multiple organs. Reduced apln signaling perturbs organismal homeostasis; mice harboring genetic deficiency of aplnr or apln exhibit enhanced cardiovascular, renal, and reproductive aging...

Background: Recent anatomic findings suggest aging-related changes of the complex fat distribution in the hand. Objectives: To rejuvenate the aging hand, we developed a targeted fat grafting technique based on the physiologic fat distribution of the hand. Methods: The dorsum of both hands was examined in 30 healthy volunteers of different age utilizing B-mode ultrasound to determine physiological changes of the aging hand. Additional anatomic dissection was performed in 10 hands of five fresh cadavers to establish the anatomic basis for the targeted restoration technique...

Aging at the cellular level is a complex process resulting from accumulation of various damages leading to functional impairment and a reduced quality of life at the level of the organism. With a rise in the elderly population, the worldwide incidence of osteoporosis (OP) and osteoarthritis (OA) has increased in the past few decades. A decline in the number and "fitness" of mesenchymal stromal cells (MSCs) in the bone marrow (BM) niche has been suggested as one of the factors contributing to bone abnormalities in OP and OA...

Fillers and toxins are safe, quick, and require no downtime; the immediately visible results can boost a man's self-esteem, confidence, youthfulness, and sense of competitiveness in the personal and professional realms of the world. The approach to using these agents has changed from ironing out the skin to remove wrinkles and lines to a restructuring of the 3-dimensional face. This new strategy, volumetric structural rejuvenation (VSR), relies on intimate knowledge of facial anatomy and the pathophysiology of aging...

Men seek cosmetic procedures for vastly different reasons than women. Men often seek discrete cosmetic services with little downtime. Male skin structure generally differs from female skin structure. Dermatologists should consider subtle differences in the psyche of the male cosmetic patient.

Men of all races are currently more open to requesting and undergoing treatments for a plethora of cosmetic concerns. Among the most common goals are procedures that combat the signs of aging, rejuvenate the skin, even out the color tone, address textural issues such as acne scarring, and improve hair disorders. Given the differences in cultural ideals and anatomic/physiologic differences in ethnic skin, it is important for physicians to be aware and sensitive to the nuances required when providing consultation and treating non-Caucasian 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.
