Filter by:Recently, numerous signaling proteins derived from adipose tissue and/or skeletal muscle have been described and are involved in the pathogenesis of obesity and the pathophysiology of aging. Current evidence suggests a role for the FGF-Klotho system, circulating cell-free DNA (cfDNA), miR-499, and exosomes not only in the pathophysiology of obesity, but also in the association with sarcopenic obesity (OS) and in a accelerated aging. The investigator´s hypothesis is that obesity, especially OS, might be the cause of advanced aging, reflected in lower levels of the FGF-Klotho system, higher concentrations of cfDNA and a change in the profiles of miRNAs and exosomes, which could have an impact on risk. cardiovascular and metabolic. For this, a descriptive cross-sectional study is proposed in 50 patients with obesity, who will be classified as OS or not, and 25 healthy controls, between 50-60 years old. The determinations are made by the IBIOMED of the University of León. To study the evolution of aging markers over a year of follow-up, a second part of the study will analyze the possible differences according to the treatments assigned to each patient in the context of real life (lifestyle changes, drugs, bariatric surgery).
This current randomized, double-blind, comparator-controlled, cross over study investigates the efficacy and safety of RiaGev™ via evaluation of NAD+, ATP, glucose, insulin, glutathione, and cortisol levels in healthy adults of ages 36-65.
BACKGROUND: Endoscopy was first used in plastic surgery for the treatment of frontal rhytides. This minimally invasive approach allows the treatment of frontal wrinkles using a practical procedure that does not directly interfere with the frontalis muscle, acting only on its antagonists. It is also possible to treat the middle third of the face, but these evolutions depends on special surgical instruments. Videoendoscopic approach in rhytidoplasty have been improved by new devices and surgical instruments. The mid third of the face can be treated in different ways. Zygomatic projection can be achieved by the use of the Dissector Assisted Malar Elevation (DAME) procedure. AIM: Evaluate the zygomatic projection achieved by DAME in videoendoscopic rhytidoplasties. METHODS: 30 non-white female patients, 30 to 59 years old, will be submitted to videoendoscopic rhytidoplasty with malar elevation by the DAME. Pre- and post-operative facial appearance will be evaluated by digital photogrammetry.
