BACKGROUND Postoperative pain is a major concern for patients undergoing facial aesthetic surgery. Aggressive efforts to reduce postoperative pain while avoiding adverse sequelae, such as nausea and vomiting, will result in an improved patient experience. Newer pharmaceuticals, medical devices, and longer-acting local anesthetics offer the potential to reduce pain and enhance patient satisfacti...

BACKGROUND Facial aesthetics and rejuvenation are evolving rapidly due to changes in products, procedures, and patient demographics. Clinicians can benefit from ongoing guidance on products, tailoring treatments to individual patients, treating multiple facial areas, and using combinations of products and ways to optimize outcomes. METHODS A multidisciplinary group of aesthetic treatment expe...

BACKGROUND AND OBJECTIVES For skin rejuvenation, microneedle fractional radiofrequency (RF) is a recently developed minimally invasive method for delivering RF energy directly into the skin using microneedle. Additionally, the use of growth factors in skin rejuvenation is emerging as a novel anti-aging treatment. We evaluated efficacy and safety of microneedle fractional RF for skin rejuvenatio...

BACKGROUND Radio frequency (RF) and chemical peels have been used for nonablative skin rejuvenation. Both of these cause collagen remodeling in the dermis and neo-collagen formation resulting in facial rejuvenation. There is limited literature on the evaluation of collagen remodeling by objective methods. OBJECTIVE To compare the benefits of monopolar radiofrequency and glycolic acid peels in...

Software aging [2] is a phenomenon observed in a software application executing continuously for a long period of time, where exhaustion of operating system resources (memory leaks), data corruption and numerical error accumulation eventually lead to performance degradation, hang/crash failures or both. To counteract this problem, Huang et al. [2] proposed the technique of software rejuvenation...

The capacity for tissues to repair and regenerate diminishes with age. We sought to determine the age-dependent contribution of native mesenchymal cells and circulating factors on in vivo bone repair. Here we show that exposure to youthful circulation by heterochronic parabiosis reverses the aged fracture repair phenotype and the diminished osteoblastic differentiation capacity of old animals. ...

Erythrocytes in human blood stored for 120 days were collected by centrifugation after dispersion in buffered physiological saline. The aged erythrocytes thus collected were incubated with inosine, adenine, glucose or other media, and their shapes and ATP levels were studied by scanning electron microscopy and a luciferine-luciferase method. The aged erythrocytes incubated in a mixture of adeni...
