Evaluation of the Glymphatic System in Rabbits Using Gadobutrol-Enhanced MR Cisternography With T1 and T2 Mapping.

Purpose: We aimed to characterize and further understand CSF circulation and outflow of rabbits. To our knowledge, there is no research on contrast material-enhanced MR cisternography (CE-MRC) with T1 and T2 mapping in the rabbit model using a clinical 3-T MR unit without a stereotaxic frame.

Materials And Methods: Twenty-one rabbits were included in the study.

MgCa-Based Alloys Modified with Zn- and Ga-Doped CaP Coatings Lead to Controlled Degradation and Enhanced Bone Formation in a Sheep Cranium Defect Model.

Mg-based biodegradable metallic implants are gaining increased attraction for applications in orthopedics and dentistry. However, their current applications are hampered by their high rate of corrosion, degradation, and rapid release of ions and gas bubbles into the physiological medium. The aim of the present study is to investigate the osteogenic and angiogenic potential of coated Mg-based implants in a sheep cranial defect model.

Cerebrovascular modelling for the management of aneurysm embolization using an intrasaccular flow diverter made by 3D printing.

Purpose: Using 3-dimensional (3D) printers, the creation of patient-specific models is possible before and after a therapeutic intervention. There are many articles about replicas for training and simulation of aneurysm clipping. However, no paper has focused on 3D replicas obtained from 3-tesla 3D time of flight (3D-TOF) MR angiography for intrasaccular flow diverter (WEB device) embolization of the cerebral aneurysms.

3D Printed Biodegradable Polyurethaneurea Elastomer Recapitulates Skeletal Muscle Structure and Function.

Effective skeletal muscle tissue engineering relies on control over the scaffold architecture for providing muscle cells with the required directionality, together with a mechanical property match with the surrounding tissue. Although recent advances in 3D printing fulfill the first requirement, the available synthetic polymers either are too rigid or show unfavorable surface and degradation profiles for the latter. In addition, natural polymers that are generally used as hydrogels lack the required mechanical stability to withstand the forces exerted during muscle contraction.

A New "Ice Globe" Method for Dilating Leaking Cervical Esophageal Strictures.

An esophageal stricture may develop during healing of a large esophageal perforation. When such a stricture occurs, mechanical dilatation is the treatment of choice. As in our case, if a cervical esophageal stricture and leakage are present together, the treatment becomes even more challenging.
