BACKGROUND: Currently, implantation of patient-specific cranial prostheses requires reoperation after a period for design and formulation by a third-party manufacturer. Recently, 3-dimensional (3D) printing via fused deposition modeling has demonstrated increased ease of use, rapid production time, and significantly reduced costs, enabling expanded potential for surgical application. Three-dimensional printing may allow neurosurgeons to remove bone, perform a rapid intraoperative scan of the opening, and 3D print custom cranioplastic prostheses during the remainder of the procedure...

Porphyra dioica is a commercial seaweed consumed all over the world, mostly in the shape of nori sheets used for "sushi" preparation. It is a well-known part of the Asian diet with health benefits, which have been associated, among others, to the high levels of n-3 and n-6 fatty acids in this red alga. However, other highly valued lipids of Porphyra are polar lipids that remain largely undescribed and can have both nutritional value and bioactivity, thus could contribute to the valorization of this seaweed...

BACKGROUND: The ablation of advanced head and neck cancer often results in large three-dimensional defects that require free tissue transfer to optimally address functional and cosmetic issues. The subscapular system is a highly versatile donor site for flaps used for head and neck reconstruction. Traditional methods of harvesting subscapular flaps require repositioning and re-preparing, which significantly increases the operative time and prevents simultaneous harvesting of the flap...

Oral diseases, particularly caries and gingivitis, continue to be widespread. Incorporating a stabilized stannous fluoride dentifrice into patients' daily oral hygiene routine is a convenient, cost effective approach to improve and protect their oral health and the appearance of their smile. Unlike other common fluorides that only provide anti-caries benefits (e.g., sodium fluoride and sodium monofluorophosphate), stabilized stannous fluoride formulations have demonstrated broader and significantly greater protection, also reducing plaque, gingivitis, erosion, sensitivity, and halitosis...

INTRODUCTION: Artificial skin has become the treatment of choice in extensive, full-thickness thermal injuries. The longest follow-up of the healing process in burn sites covered with the Integra Bilayer Matrix Wound Dressing onto the wound published to date was at around five years after application. In our case report, we describe the clinical and histological analysis of an extensive, full-thickness thermal injury 14 years on from treatment with the bilayer matrix wound dressing. CASE STUDY: A nine-year-old boy suffered a full-thickness skin loss over 85% of his body surface area following a fire accident...

Christopher M Stewart, Jonathan H Norris
The medial canthus represents one of the most challenging regions of the face to reconstruct due to the anatomical structures present, the concavity of the area, and the differences in skin texture. We present a case series of 11 patients whose defects were reconstructed with a single V-Y island pedicle flap running along the nasofacial sulcus. Our single-stage flap which modified and simplified a previously described technique achieves similar cosmetic and postoperative outcomes along with a high level of patient satisfaction in an area which can be reconstructed in a variety of ways, often with suboptimal results...

Modern food processing results in considerable amounts of side-products, such as grape seeds, walnut shells, spent coffee grounds, and harvested tomato plants. These materials are still rich in valuable and biologically active substances and therefore of interest from the perspective of waste management and "up-cycling". In contrast to traditional, often time consuming and low-value uses, such as vermicomposting and anaerobic digestion, the complete conversion into nanosuspensions unlocks considerable potentials of and new applications for such already spent organic materials without the need of extraction and without producing any additional waste...
