The use of Micro-Laser Raman spectroscopy technology for quantitatively determining gas carbon isotope composition is presented. In this study, 12CO2 and 13CO2 were mixed with N2 at various molar fraction ratios to obtain Raman quantification factors (F12CO2 and F13CO2), which provide a theoretical basis for calculating the δ13C value. And the corresponding values were 0.523 (0<C12CO2/CN2<2) and 1.11998 (0<C13CO2/CN2<1.5) respectively. It has shown that the representative Raman peak area can be used for the determination of δ13C values within the relative errors range of 0...

Full-thickness skin grafts (FTSGs) are frequently used to treat patients with burn injuries and to repair defects rendered by excisional (including Mohs) surgery. The evidence for corrective laser surgery after scar formation is well established. With regard to laser treatment of FTSG, the evidence is sparse. Laser treatment after FTSG is a novel concept, with minimal literature. We present a case series, one of the first to our knowledge, of the treatment of FTSG with fractional CO 2 laser in five patients after Mohs surgery...

Background: It is a challenge to treat acne scars and a multimodal combination approach is necessary. While fractional CO 2 lasers (FCLs) are an established treatment option, the role of platelet-rich plasma (PRP) in the treatment of acne scars is not established though it is being used extensively in other fields of medicine owing to its healing properties. We combined the two methods to assess the proposed synergistic action on acne scars. Aims and Objectives: To evaluate the effect of FCL alone vs FCL combined with PRP on the quality of acne scars...

Background: Fractionated, ablative lasers are usually associated with post-treatment erythema, edema, and crusting, which can last from 5 to 14 days. Conjugated linolenic acid, an omega-5 fatty acid, has significant antioxidant and anti-inflammatory properties, and has been shown to stimulate keratinocyte proliferation and epidermal regeneration. By modulating the early inflammatory milieu and directly affecting skin structure and function, conjugated linolenic acid might therefore shorten downtime following fractionated ablative laser resurfacing of the face...

OBJECTIVE: Vulvovaginal atrophy (VVA) is a condition frequently observed in menopause. Its symptoms can significantly affect the quality of life of patients. Since VVA is related to estrogen deficiency, chemotherapy and hormone therapy for breast cancer (BC) might cause VVA by inducing menopause. Given the lack of effective treatment for VVA in BC survivors, we retrospectively evaluated the efficacy and tolerability of fractional microablative CO2 laser therapy in these patients. METHODS: We treated 82 BC survivors with three cycles of CO2 laser after failure of topical nonestrogenic therapy...

REVIEW
R Thiesmann
Blepharoplasty is one of the most frequently performed plastic cosmetic interventions. For this purpose the CO2 laser is an instrument that can be used as a laser scalpel to cut as well as in its ablative function to remove skin irregularities, such as scars and tumors and also to treat changes of the skin due to aging. Fractionated laser irradiation reduces the duration of skin redness and the postoperative rehabilitation time after a resurfacing. The advantages of the CO2 laser are a gentle intraoperative preparation and less postoperative swelling due to an additional cauterization of blood vessels...
