Naturally sourced porcine collagen has been approved for filling moderate MK-2206 inhibitor to deep facial wrinkles and nasolabial folds.
To our knowledge, naturally sourced porcine collagen filler has not yet been tried as a treatment for correcting atrophic acne scars.
OBJECTIVE To objectively assess and directly compare the efficacy and safety of subcuticular incision versus naturally sourced porcine collagen dermal filler in correcting atrophic and rolling acne scars.
MATERIALS AND METHODS We performed a prospective, randomized, split-face, single-blind study to evaluate intermediate long-term efficacy of subcision and collagen dermal filler on 20 unilateral faces. Patients and blinded physicians evaluated results. RESULTS Patients rated subcision as superior to collagen dermal filler at 3 months (p = .03). At 6 months, subcision had a slightly higher rating than collagen dermal filler (p = .12). Blinded evaluators leaned toward subcision at 3 months (p = .12) and at 6 months showed no preference (p = .69).
CONCLUSION Subcuticular incision and naturally sourced porcine collagen dermal
filler appear to be efficacious for improving atrophic and rolling acne scars. Patients may prefer subcuticular incision over collagen dermal filler. Blinded Selleckchem HKI-272 evaluators found no significant difference between the treatments.”
“A comparative investigation of charge transport properties is presented, for polymeric [poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS)], single-wall carbon nanotube (SWNT) and inorganic (indium tin oxide, ITO), transparent conducting electrodes. The polymeric and nanotube systems show hopping transport at low temperatures, in contrast with the disordered-metal transport in ITO. The low temperature magnetotransport (up to 11 T) and high electric-field transport (up to 500 V/cm) indicate the significant ASP2215 concentration role of nanoscopic scale disorder for charge transport in polymer and nanotube based systems. The results show that characteristic length scales like localization length correlates with the nanomorphology in these systems. Further, the high
frequency conductivity measurements (up to 30 MHz) in PEDOT:PSS and SWNT follow the extended pair approximation model [sigma(omega)=sigma(0)[1+(omega/omega(0))(s)].”
“BACKGROUND Treatment of syringoma aims to destroy the dermal tumor using methods that can include surgical excision, electrodessication, cryosurgery, chemical peeling, and laser ablation, but complete removal of syringomas is often unsuccessful, and recurrence occurs frequently. OBJECTIVE To investigate the therapeutic efficacy of an ablative 10,600-nm carbon dioxide fractional laser system (CO(2) FS) for the treatment of periorbital syringomas. METHODS Thirty-five patients with periorbital syringomas were treated with two sessions of CO(2) FS at 1-month intervals.
