Background: Applying 3D printing technology for the fabrication of custom-made orthoses provides significant advantages, including increased ventilation and lighter weights. Currently, the design of such orthoses is most often performed in the CAD environment, but creating the orthosis model is a time-consuming process that requires significant CAD experience. This skill gap limits clinicians from applying this technology in fracture treatment. The purpose of this study is to develop a parametric model as the design generator for 3D-printed orthoses for an inexperienced CAD user and to evaluate its feasibility and ease of use via a training and design exercise...

Skin grafting is often the first choice for closing forehead defects. However, the aesthetics of skin grafting-reconstructed forehead defects are still not accepted by a large number of patients. With the technological advancement of laser hair removal, scalp flaps have been considered as donors for reconstruction of forehead defects. We evaluated 10 cases of forehead defect reconstructions with expanded scalp flaps followed by hair removal by an 800 nm diode laser. All flaps survived uneventfully and underwent 4-6 laser treatments for hair removal...

In recent years, DNA computing frameworks have been developed to create dynamical systems which can be used for information processing. These emerging synthetic biochemistry tools can be leveraged to gain a better understanding of fundamental biology but can also be implemented in biosensors and unconventional computing. Most of the efforts so far have focused on changing the topologies of DNA molecular networks or scaling them up. Several issues have thus received little attention and remain to be solved to turn them into real life technologies...

Target identification is a high-priority, albeit challenging, aspect of drug discovery. Diazirine-based photoaffinity probes (PAPs) can facilitate the process by covalently capturing transient molecular interactions. This can help identify target proteins and map the ligand's interactome. Diazirine probes have even been incorporated by cellular machinery into proteins. Embarking on the synthesis of customized PAPs, containing either an aliphatic or trifluoromethyl phenyl diazirine, can be a considerable endeavor, particularly for medicinal chemists and chemical biologists new to the field...
