The Use of the Facial Sinus Wall as Bone Shell Onlay Graft for Maxillary Posterior Ridge Reconstruction: A Retrospective Case Series.

Purpose: To evaluate the performance and clinical outcome of vertical and horizontal bone augmentation (VHBA) in posterior maxillary regions combining lateral window sinus floor elevation (LWSFE) with a horizontal bone shell technique applying the maxillary facial sinus wall as a bone plate.

Materials And Methods: In 18 patients, LWSFE was combined with a horizontal bone shield augmentation procedure utilizing the maxillary facial sinus bone wall as a lateral bone plate. Both the sinus cavity and the lateral bone box created were grafted with a mixture of autogenous bone/venous blood and bovine bone mineral.

Enhanced Feedstock Processability for the Indirect Additive Manufacturing of Metals by Material Extrusion through Ethylene-Propylene Copolymer Modification.

Filament-based material extrusion (MEX) represents one of the most commonly used additive manufacturing techniques for polymer materials. In a special variation of this process, highly filled polymer filaments are used to create metal parts via a multi-step process. The challenges associated with creating a dense final part are versatile due to the different and partly contrary requirements of the individual processing steps.

Maxillary Sinus Augmentation with Anorganic Bovine Bone Mineral of Different Particle Sizes: A Split-Mouth Study with Histomorphometric, Radiographic, and Clinical Analyses.

Purpose: The aim of the present study was to compare the histomorphometrically evaluated new bone formation (NB), the radiographically measured graft stability, and the clinical implant outcome for maxillary sinus augmentation grafted with deproteinized bovine bone mineral (DBBM) with either small (Bio-Oss-S, Geistlich) or large (Bio-Oss-L, Geistlich) particles.

Materials And Methods: Using a split-mouth study design, bilateral maxillary sinus augmentation was performed in 13 patients either with Bio-Oss-S particles (0.25 to 1 mm) or Bio-Oss-L particles (1 to 2 mm).

Endothelial receptor proteins in acute venous thrombosis and delayed thrombus resolution in cerebral sinus vein thrombosis.

Background And Purpose: Cerebral sinus venous thrombosis (CSVT) is a rare but life-threatening disease and its diagnosis remains challenging. Blood biomarkers, including D-Dimer are currently not recommended in guidelines. Soluble endothelial receptor proteins (sICAM-1, sPECAM-1 and sVCAM-1) have been shown to be promising diagnostic biomarkers in deep vein thrombosis (DVT) and pulmonary embolism (PE).

Dispersal of juvenile Barrow's goldeneyes (Bucephala islandica) mirrors that of breeding adults.

Barrow's goldeneyes across western North America have been shown to have a high degree of subpopulation independence using several data types. However, evidence for structured populations based on mitochondrial DNA, band recoveries, and tracking of adults is discordant with evidence from autosomal DNA. We used satellite tracking data from both juveniles and adults marked on natal and breeding grounds, respectively, in British Columbia, Canada to evaluate the hypothesis that male-biased juvenile dispersal maintains genetic panmixia of Pacific Barrow's goldeneyes otherwise structured by migratory movements and high winter and breeding site fidelity of adults.
