A Pilot Study on the Impact of Smoking on Adipose Derived Stem Cell Function in Burn Patients.

Adipose-derived stem cells (ADSCs) have an important role in the modulation of burned tissue repair through the release of paracrine factors that stimulate the wound healing response. In this study, we tested the hypothesis that smoking status alters the profile of paracrine factors secreted from ADSCs isolated from damaged adipose tissue. Adipose tissue was collected from adult patients (N=8) with severe burn injuries (>20% total body surface area) at the index operation.

PRC2-EZH1 contributes to circadian gene expression by orchestrating chromatin states and RNA polymerase II complex stability.

Circadian rhythmicity of gene expression is a conserved feature of cell physiology. This involves fine-tuning between transcriptional and post-transcriptional mechanisms and strongly depends on the metabolic state of the cell. Together these processes guarantee an adaptive plasticity of tissue-specific genetic programs.

Hybrid Inferior Pedicle Reduction Mammaplasty with Free Nipple Grafts in a Patient with Gigantomastia.

Gigantomastia presents a unique set of challenges for preservation of the nipple-areola complex in patients undergoing reduction mammaplasty. Historically an indication for breast amputation and free nipple graft (FNG), gigantomastia is now commonly treated using pedicle-based reconstruction. We present a case combining these two surgical techniques, using an inferior-pedicle reduction with an FNG in the management of extreme breast hypertrophy with 11,300 g in total resected.

Incidence of Orbital Mucocele following Orbital Floor Fracture Repair.

Mucoceles can often present as a complication after prior sinus surgery or maxillofacial trauma when mucosal drainage is obstructed. Their presence in the orbit following orbital wall fracture and subsequent repair represent an exceedingly rare complication whose occurrence is limited to a few reported cases in the literature. In these patients, continuous cyst expansion and subsequent mass effect may lead to ophthalmic symptoms, including orbital pain, proptosis, diplopia, and globe dystopia.

Long-acting exenatide does not prevent cognitive decline in mild cognitive impairment: a proof-of-concept clinical trial.

Purpose: According to preclinical evidence, GLP-1 receptor may be an actionable target in neurodegenerative disorders, including Alzheimer's disease (AD). Previous clinical trials of GLP-1 receptor agonists were conducted in patients with early AD, yielding mixed results. The aim was to assess in a proof-of-concept study whether slow-release exenatide, a long-acting GLP-1 agonist, can benefit the cognitive performance of people with mild cognitive impairment (MCI).
