Abstract
The development of efficient strategies for the magnetic hyperthermia ablation of tumors remains challenging. To overcome the significant safety limitations, we developed a thermally contractible, injectable and biodegradable material for the minimally invasive and highly efficient magnetic hyperthermia ablation of tumors. This material was composed of hydroxypropyl methyl cellulose (HPMC), polyvinyl alcohol (PVA) and Fe3O4. The thermal contractibility of HPMC/Fe3O4 was designed to avoid damaging the surrounding normal tissue upon heating, which was confirmed by visual inspection, ultrasound imaging and computed tomography (CT). The efficient injectability of HPMC/Fe3O4 was proven using a very small needle. The biosafety of HPMC/Fe3O4 was evaluated by MTT and biochemical assays as well as flow cytometry (FCM). All the aforementioned data demonstrated the safety of HPMC/Fe3O4. The results of in vitro and ex vivo experiments showed that the temperature and necrotic volume of excised bovine liver were positively correlated with the HPMC/Fe3O4 weight, iron content and heating duration. The in vivo experimental results showed that the tumors could be completely ablated using 0.06 ml of HPMC/60%Fe3O4 after 180 s of induction heating. We believe that this novel, safe and biodegradable material will promote the rapid bench-to-bed translation of magnetic hyperthermia technology, and it is also expected to bring a new concept for the biomaterial research field.

Abstract
BACKGROUND In the field of cosmetic medicine, patient satisfaction is an important and common indicator used to measure the efficacy of the treatment. However, it is insufficient to prove objectively that the benefit of the specific factors involved in the cosmetic outcomes. The practitioner should be aware of these assessment tools, in particular in case of demanding or litigious patients. OBJECTIVE The aim of this review was to establish a list and discuss the subjective and objective methods used to assess facial aesthetic rejuvenation treatments. METHODS A systematic literature search was performed using the Pubmed search engine. Studies published over the last 5 years, i.e. between January 2010 and January 2015 were considered for review. The following keywords were used: "aesthetic treatment", "facial rejuvenation", and "subjective evaluation" or "objective evaluation". RESULTS Of the 446 articles identified by the search strategy, 47 articles focused specifically on facial rejuvenation and on the efficacy of aesthetic medical treatments were retrieved for review. Thirty-seven articles used quantitative methods to assess aesthetic treatment outcomes and only 12 used subjective methods. The different assessment methods were listed according to the tools used and treatment indications. CONCLUSION This review will help in choosing adequate methods to assess facial rejuvenation medical treatment. It is important to combine these tools adequately to improve the assessment. There is no current consensus on assess facial rejuvenation treatments but we noted that objective assessment methods seem helpful. NO LEVEL ASSIGNED This journal requires that authors assign a level of evidence to each article.
