[1] Drainage networks on Titan, Earth, and Mars provide the only known examples of non-volcanic fluvial activity in our solar system. The drainage networks on Titan are apparently the result of a methane-ethane cycle similar to Earth’s water cycle. The scarcity of impact craters and the uneven distribution of fluvial dissection on Titan suggest that the surface may be relatively young. The purp...

Ablative fractional skin resurfacing represents a new possibility that allows for shorter downtime and minimizes the risk of possible side effects compared to classical full ablative Er:YAG and CO2 treatment. To evaluate the potential benefits of fractional treatment with Er:YAG for skin resurfacing, we performed a clinical and histological comparison of the healing process after fractional and...

The demand for skin resurfacing and rejuvenating procedures has progressively increased in the last decade and has sparked several advances within the skin resurfacing field that promote faster healing while minimizing downtime and side effects for patients. Several technological and procedural skin resurfacing developments are being integrated into clinical practices today allowing clinicians ...

We compared aged adult and fetal retinal pigment epithelium (RPE) migration and proliferation in cell culture. Aged adult RPE resurfaced on dishes coated with human or mouse laminin, human or rat collagen I, human or mouse collagen IV, or human fibronectin. Resurfacing was best on bovine corneal endothelial cell extracellular matrix. Resurfacing was worst on mouse laminin. Fetal RPE resurfacing...

Aims Debate remains whether the patella should be resurfaced during total knee replacement (TKR). For non-resurfaced TKRs, we estimated what revision rate would have been if had resurfaced, and examined risk of re-revision following secondary patellar resurfacing. Methods A retrospective observational study National Joint Registry (NJR) was performed. All primary TKRs for osteoarthritis alone p...

INTRODUCTION The aim of this study was to look at the different claims made about hip resurfacing arthroplasty in the popular UK print media and how this relates to findings in the scientific literature. METHODS A review of UK popular print media from January 1992 to June 2011 was performed using the Lexis(®) Library online news database. Only articles discussing the clinical results of hip ...

The author provides his perspective on resurfacing procedures in dark-skinned patients, advising a cautious approach to laser resurfacing. Laser complications in Fitzpatrick skin types III to VI, including hyperpigmentation, hypopigmentation, and scarring, are well documented. Unlike chemical peeling and dermabrasion, with laser resurfacing, preoperative treatment does not control postoperative...

BACKGROUND Fractional photothermolysis, an approach to laser skin resurfacing that creates microscopic thermal wounds in skin separated by islands of spared tissue, was developed to overcome the high incidence of adverse events and prolonged healing times associated with full coverage ablative laser procedures. OBJECTIVE To examine whether fractional nonablative laser resurfacing induces skin...

BACKGROUND AND OBJECTIVE Pulsed carbon dioxide (CO(2)) laser devices are considered highly effective treatment options for skin resurfacing. However, the high risk for significant treatment complications following CO(2) resurfacing has warranted the development of new treatment modalities. The concept of fractional photothermolysis was developed to address the shortcomings of ablative and non-a...

introduction: acne scar is formed after severe episodes of acne in teen and earlyadult years. several treatment options have been used for depressed acne scars suchas punch grafting, punch excision carbon dioxide (co2) laser etc. moreover, studiesshow that laser skin resurfacing such as co2 fractional can effectively treat depressedacne scars. we investigated the efficacy of fractional co2 lase...
