The world of wounds comes together
No full textWe are fast approaching the fifth World Union of Wound Healing Societies (WUWHS) conference, to be held in Florence next September 25–29 (www.wuwhs2016.com). The spirit of WUWHS was always to offer a valid opportunity to wound practitioners and other people involved to get together and exchange latest advances in the field of wound management. The scientific programme in Florence is exciting with over 300 confirmed invited speakers from all over the world and more than 1000 free abstracts, to be distributed as oral and poster presentations. The scientific sessions have been completely redesigned by the scientific committee, compared with previous WUWHS conferences and updated with brand new topics in basic and clinical science. The Rising Star concept will be introduced in Florence for the first time at a WUWHS conference and selected young scientists will be given the title Rising Star for their contribution to the scientific programme. We are also proud to announce another new event; the opportunity for the WUWHS sister societies to hold their sessions before the opening ceremony on sunday. Several new WUWHS consensus and position documents will be launched during the conference—an educational established opportunity to spread, on a global level, key messages in wound management
Biologic drugs in wound management
No full textThe role of dermatologists in chronic wound management is increasing. They play a crucial role in the differential diagnosis of an atypical wound where wound and skin biopsies are mandatory. Because of this dermatopathologists have developed specific immunostaining techniques, which offer greater choice in the armamentarium of diagnostics, while improving the understanding of the complex mechanisms of wound healing

Shaping molecular excited-state properties by means of localized surface plasmon resonances
Full text linkControlling light-matter interactions at the nanoscale holds promise for successfully dealing with ever-increasing worldwide issues like energy consumption and shortage. In this regard, metallic nanostructures featuring light-induced localized surface plasmon resonances proved to be an efficacious way of manipulating light at the nanoscale, thus paving the way for controlling the energy flow at molecular scale. Indeed, in recent years many works have illustrated the possibility of modifying molecular properties, e.g. molecular photoluminescence, Raman scattering, energy transfer and so forth, by cleverly harnessing plasmonic effects of metallic nanostructures. Nowadays, these findings have even led to state-of-the-art experimental techniques where single-molecule imaging with sub molecular resolution is possible by using visible light, thus incredibly going beyond light diffraction limit. These complex phenomena are often affected by different system features and span various length and time scales, which makes the rationalization of experimental results an arduous task. In this respect, theory can be instrumental not only to unravel processes which are typically hidden behind experimental observables, but also to investigate new effects that could be later experimentally probed. This thesis aims at shining light on the complex and rich physico-chemical properties arising from coupling molecules with plasmonic nanostructures by combining ab initio molecular modelling with a classical or quantum description of arbitrarily shaped metallic nanostructures, the latter described as homogeneous polarizable objects. Novel methods development and applications to systems of much scientific interest are shown, ranging from plasmon-enhanced single-molecule photoluminescence, plasmon-mediated chirality to collective plasmon-molecules strong-coupling. In many of those cases, a direct comparison between theoretical simulations and state of the art experimental evidence reveals that nanostructures features, such as metal geometrical details and plasmon dynamics drastically impact on the resulting molecular properties, therefore constituting a possible control knob to further manipulate energy at the nanoscale
Fractional epidermal skin grafting
No full textSkin grafts can be obtained from several sources, both human and animal. Skin grafts can include all or a portion of the skin, including the epidermis and dermis.1 More recently, the use of skin substitutes, dermal fillers and tissue expanders has increased surgeons’ and dermatologists’ ability to cover skin defects resulting from burns, traumatic injury, chronic wounds or excision of cancerous lesions.2 The major sources of skin grafts are autografts, homografts and xenografts. Skin substitutes, dermal fillers and tissue expanders provide additional dermal or epidermal components (or both) for wound coverage and in order to stimulate wound healing
