Bioprinting Perfusable and Vascularized Skeletal Muscle Flaps for the Treatment of Volumetric Muscle Loss

Advanced Healthcare Materials, EarlyView.
Volumetric muscle loss (VML) due to trauma or surgery, often leads to physical impairments. Traditional treatments rely on autologous flaps, limited by muscle availability often leading to donor site morbidity. This study presents multimodal bioprinting as an innovative approach for fabricating vascularized muscle flaps with 3D‐printed macrovessels ...

Early to middle Miocene foraminifera from the deep-sea Congo Fan, offshore Angola [PDF]

, 2008
Analysis of a 630m section of an exploration well penetrating the distal part of the Congo Fan (~2000m water depth) yielded high abundance and diversity assemblages of agglutinated and calcareous benthic foraminifera.

Changes in the midpalatal and pterygopalatine sutures induced by micro-implant-supported skeletal expander, analyzed with a novel 3D method based on CBCT imaging. [PDF]

, 2017
BackgroundMini-implant-assisted rapid palatal expansion (MARPE) appliances have been developed with the aim to enhance the orthopedic effect induced by rapid maxillary expansion (RME).

Motor‐Free Soft Robots for Cancer Detection, Surgery, and In Situ Bioprinting

Advanced Healthcare Materials, EarlyView.
Novel motor‐free soft robots for cancer detection, surgery, and in situ bioprinting–are presented. This master‐slave system is constructed from soft fibrous syringe architectures, removing the need for electrical motors and complex control mechanisms, while reducing the physical tremors.

The sutured Thurston norm [PDF]

arXiv, 2006
For sutured 3-manifolds M, there is a sutured Thurston norm due to Scharlemann. We show how depth one foliations of M and corresponding fibrations and the usual Thurston norm on the double of M are useful tools for computing this norm. In many examples, the faces of the unit ball of the sutured norm are related to cones of depth one foliations of M but

Biohybrid Vascular Graft Made of Textile‐Reinforced Elastin‐Like Recombinamers and Its Preservation via Drying Processes

Advanced Healthcare Materials, EarlyView.
Clinical translation of biohybrid medical implants requires the previous implementation of drying schemes that can facilitate their sterilization and storage. This study addresses that critical aspect and elucidates the impact of drying on biohybrid vascular grafts, highlighting the need for implant‐specific drying strategies to ensure safety ...

Revision of Dadagulella gen. nov., the “Gulella radius group” (Gastropoda: Streptaxidae) of the eastern Afrotropics, including six new species and three new subspecies [PDF]

, 2013
The genus Dadagulella gen. nov. is described to include 16 species of small, dentate, ovateacuminate Afrotropical snails. An identification key is provided and biogeography, anatomy and systematics are discussed. The type species is the Kenyan D. radius (

Contact structures, sutured Floer homology and TQFT [PDF]

arXiv, 2008
We describe the natural gluing map on sutured Floer homology which is induced by the inclusion of one sutured manifold (M',\Gamma') into a larger sutured manifold (M,\Gamma), together with a contact structure on M-M'. As an application of this gluing map, we produce a (1+1)-dimensional TQFT by dimensional reduction and study its properties.

Designing for Degradation: Transient Devices Enabled by (Nano)Cellulose

Advanced Materials, EarlyView.
Recent progress in transient devices enabled by (nano)cellulosic materials is reviewed. Transiency mechanisms, advantages of nanocelluloses, and a suite of applications are discussed. A circular thinking approach coupled with life cycle assessment is applied to critically revisit the potential, advantages, and challenges of nanocellulose‐enabled ...
