Three-Dimensional Planning for Vascularized Bone Grafts: Implementation and Surgical Application for Complex Bone Reconstruction in the Hand and Forearm.

Vascularized bone grafts have been successfully established for complex bone defects. The integration of three-dimensional (3D) simulation and printing technology may aid in more precise surgical planning and intraoperative bone shaping. The purpose of the present study was to describe the implementation and surgical application of this innovative technology for bone reconstruction.

3D Technology for Autologous Breast Reconstruction: Increased Aesthetic Outcomes and Quality of Life Using Patient-Specific Templates.

Background: In autologous breast reconstruction accomplishing aesthetically pleasing outcomes represents an integral challenge. 3-dimensional technology may aid in accurate flap shaping and subsequent breast appearance.

Objectives: The aim of this study was to evaluate the applicability of 3-dimensional technology for surgical planning and its influence on outcomes for breast reconstruction.

Increased basal fibronectin is sufficient to promote excess endothelial cell matrix assembly causing localized barrier dysfunction.

Endothelial cell behavior is regulated by subendothelial extracellular matrix (ECM). The ECM protein fibronectin (FN) is rare in healthy blood vessels but accumulates in disease accompanied by endothelial dysfunctions. Here, we report that excess assembly of FN disrupts key endothelial functions.

Identification of a fibronectin-binding protein signature associated with idiopathic pulmonary fibrosis.

The extracellular matrix (ECM) is a critical component of tissue where it provides structural and signaling support to cells. Its dysregulation and accumulation lead to fibrosis, a major clinical challenge underlying many diseases that currently has little effective treatment. An understanding of the key molecular initiators of fibrosis would be both diagnostically useful and provide potential targets for therapeutics.

Simultaneous identification and quantification of three water-soluble polymers (PVP, PNVCL and PEI) in wastewater samples by continuous-flow off-line pyrolysis GC/MS.

In environmental analysis, the detection of water-soluble synthetic polymers (WSSP) presents considerable challenges. Thus, a precise and reproducible analytical method was developed using continuous-flow off-line pyrolysis with gas chromatography/mass spectrometry (GC/MS) to simultaneously identify multiple water-soluble polymers from a single environmental sample. WSSP are widely used in multiple industries as hydrogels due to their hydrophilic character and potential biocompatibility.
