Flippase‐Mediated Hybrid Vesicle Division

open access: yesAdvanced Materials, EarlyView.
The successful reconstitution of Drs2p–Cdc50p flippase in small and giant polymer lipid hybrid vesicles is illustrated. The hybrid vesicles show adenosine 5′‐triphosphate consumption and flipping of 2‐dioleoyl‐sn‐glycero‐3‐phospho‐l‐serine lipids from the inner to the outer leaflet.

Thermal Annealing Enhances Piezoelectricity and Regenerative Potential of PVDF‐TrFE Nanofiber Scaffolds

open access: yesAdvanced Materials Technologies, EarlyView.
Thermal annealing improves the structure, stiffness, and piezoelectric properties of poly(vinylidene flouride‐trifluoroethylene) (PVDF‐TrFE) nanofiber scaffolds. These annealed scaffolds promote Schwann cell proliferation and matrix remodeling in vitro and demonstrate in vivo biocompatibility.

Computer-aided segmentation and estimation of indices in brain CT scans [PDF]

open access: yes, 2014
The importance of neuro-imaging as one of the biomarkers for diagnosis and prognosis of pathologies and traumatic cases is well established. Doctors routinely perform linear measurements on neuro-images to ascertain severity and extent of the pathology ...

Investigation of Exothermic Behaviors of Energetic Particles in Microfluidics Channels

open access: yesAdvanced Materials Technologies, EarlyView.
Scheme and representative frames of delivery, ignition, and combustion process of core@shell Al@CuO energetic material in a microchannel. The electrical discharge occurred at the throat of microchannel leads to the combustion of the energetic reaction, causing the formation of high‐momentum butterfly‐shaped jet at the throat.

Swift Spontaneous Regression of a Pediatric Traumatic Acute Subdural Hematoma

open access: yesCase Reports in Neurology, 2019
We report the case of a 4-year-old girl with acute subdural hematoma who presented to the emergency department after an unwitnessed fall of the balcony. The hematoma was hyperdense along the left convexity of 9 mm thickness with a consequent mass effect ...
