Over the last decade, there has been a shift in the way aesthetic surgeons approach facial rejuvenation. With recognition of the value of volume enhancement in achieving a more youthful appearance, as well as the ease of office procedures offering minimal downtime and predictable results, there has been a concomitant explosion in the soft tissue filler market. Given the vast array of filler pro...

The photo-curing behavior of composites containing nanosized SiO2 in an acrylated hyperbranched polymer matrix was investigated by means of photo differential scanning calorimetry. The chemical conversion data were analyzed using an autocatalytic model, paying close attention to the influence of composition and UV intensity. It was shown that the reaction order and the autocatalytic exponent we...

In Danish the base position of the negation and negated quantifier phrases is between the subject and the finite verb in embedded clauses. However, in embedded clauses introduced by a non-veridical complementizer such as hvis (‘if’) or om (‘whether’) the negation and negated quantifier phrases can also appear between the complementizer and the subject. This phenomenon is referred to as preposed...

Quercus-Pinus forests of the eastern USA cover millions of hectares and span a variety of ecoregions. Understanding the influence of natural disturbance on developmental and successional pathways is important for managers that wish to sustain Pinus spp. in these mixtures. Quantifying developmental and successional patterns in this forest type can help assess the need to actively manage natural ...

A new type of needle system combines 2 parts, an inner needle and an outer needle. The inner needle is used for filler injection and the outer needle acts as a guiding needle that can observe blood reflow when inserting into the vessel lumen during injection process. This new needle system can be used for all kinds of filler, providing real time monitoring for physician and preventing intravasc...

Properties of samples containing polyurethane (PU), poly(vinyl acetate) (PVAc) and nanosize particles of calcium carbonate (CaCO3) are correlated with concentrations of these components. Interphase phenomena in PU/PVAc/CaCO3 nanohybrids have been studied before, we focus here on wear and scratch resistance. In addition to polymer blends containing CaCO3, the effects of adding CaCO3 with grafted...

results all patients experienced improvement in the wrinkles of the side treated by the combination therapy compared to the other side. in addition, less complication was observed in the side that underwent combination therapy. conclusions our study showed that autologous fat in combination with platelet gel might have better cosmetic results as well as lesser complications in the healing of na...
