Filter by:Soft tissue augmentation with injectable hyaluronic acid (HA) is a well-established modality for the correction of facial volume loss, fat atrophy, fine lines, and wrinkles. HA is a glycosaminoglycan that is composed of repeating D-glucuronic acid and D-N-acetylglucosamine disaccharide units. Because HA is a natural and inert constituent of the dermis, it represents an ideal substance for soft tissue augmentation. Current FDA-approved HA fillers are typically utilized to either directly target specific cutaneous rhytids or to restore overall contours by placement into fat pads or along bony structures that have remodeled with age. Restylane® Silk is a transparent injectable HA gel that received FDA approval in June 2014 for use in the lips and peri-oral region. Its unique synthesis results in smaller and finer particles that demonstrate significant hygroscopic properties and give rise to the potential for unique applications. One such application concerns the concept of "skin boosting" whereby microaliquots of HA are placed into the skin to induce biophysical improvement in dermal characteristics (1). Using this technique, a recent split-body study by Streker et al. demonstrated significant aesthetic improvements in face, hands and décolletage (2). However, there have been no well-controlled studies with validated aesthetic outcomes utilizing Restylane® Silk in this fashion to date. Because of the unique combination of ultra-fine product and high water-attracting capability, the investigators hypothesize that microinjections of Restylane® Silk can be used in a grid-like injection pattern for rejuvenation of the aging cheek.
Human adipose tissue has been shown to contain a group of cells that possess extensive proliferative capacity and the ability to differentiate into multiple cell lineages. Cells isolated from the fatty portion are termed processed lipoaspirate cells that contain adipose-derived regenerative cells (ADRCs). ADRCs are most conveniently extracted from tissue during an elective cosmetic liposuction procedure but may also be obtained from resected adipose tissue. This study is aimed to verify if there are differences between the number and viability of cells obtained from patients with different age, sex, Body Mass Index (BMI), smoking and physical activity, within the different amount of processed fat.
Obesity is associated with many undesirable health effects and disease, and middle age is associated with increased risk for disease. Unfortunately, while others have looked at the effects of obesity, gender, and middle age, the combined effects of obesity and middle age on men's ability to do work in hot industrial environments have not been satisfactorily investigated. This small study evaluates the heat tolerance of lean and obese middle aged men both while exercising and resting and the ways in which each compensate for and dissipate increasing environmental heat and heat generated by the body while exercising. As obesity is a worldwide public health crisis and as populations in many industrialized nations age, it is important to understand the combined effects of obesity and middle age for men on their ability to safely work in hot environments. Such information will permit establishing and revising of safe work standards and inform public health outreach to the target population, itself.
The purpose of this study is to find out if quercetin can increase blood levels of hypoxia-inducible transcription factor 1 (HIF-1 protein) and to see if there is a corresponding increase in blood flow to the brain.
The purpose of this study is determine if the iron chelator, desferrioxamine can increase blood levels of hypoxia-inducible transcription factor 1 (HIF-1 protein) and to see if there is a corresponding increase in blood flow to the brain.
The purpose of this study is to examine the effect of Sculptra Aesthetic on the cosmetic rejuvenation of the midface complex. The investigators plan to both qualitatively determine the restoration of midface architecture as well as quantitatively document the change in midface volume by employing three-dimensional (3D) surface imaging which critically analyzes volumetric tissue changes. Our hypothesis is that patients who receive Sculptra Aesthetic injections will experience significant improvement in facial midface volume restoration. - Measure the midfacial volumetric correction from Sculptra Aesthetic treatment, using three-dimensional digital surface imaging - Determine the mean change from baseline in facial contour via quantitative volumetric measurements - Correlate volumetric correction with clinical improvement as measured by the Facial Lipoatrophy Panel grading system - Correlate the mean volumetric change in midfacial treatment area with the amount of product used - Obtain photographs pre- and post-treatment for the purpose of providing a subject visual aid during the course of treatment - Collect safety data
