SHORT SEGMENT FIXATION OF THORACOLUMBAR FRACTURES WITH PEDICLE FIXATION AT THE LEVEL OF THE FRACTURE
Euromediterranean Biomedical Journal, 2018 Thoracolumbar fractures are very frequent injuries, for both anatomical and biomechanical reasons. The most appropriate surgical treatment is still debatable.

Advanced Science, EarlyView.A novel B2‐ordered Ti‐Zr‐V‐Al medium‐entropy intermetallic is developed through controlled metastability engineering, which activates an ordered TRIP effect via a new B2→D019‐α2 transformation with a distinctive {0001}α2//{110}B2, <11‐20>α2//<100>B2 orientation relationship. This alloy achieves an elongation of ∼7%, a strength of ∼1.1 GPa, and superior

Programmable Self‐Heating Microneedle Patch for on‐Demand Postprandial Glucose Management
Advanced Science, EarlyView.A programmable self‐heating microneedle patch enables on‐demand, timed‐sequence insulin delivery via user‐triggered quadrant activation. Each activation generates localized heat that melts a phase‐change barrier, accelerating drug release. In diabetic rats, sequential quadrant activation counteracts four meal‐mimicking glucose spikes over 24 h without ...

CT in thoracic and lumbar burst fractures
Acta Orthopaedica et Traumatologica Turcica, 2020 Eighty one patients who developed thoracolumbar fractures after trauma were evaluated with direct radiography and CT. Thirty six of cases were burst fractures. The changes of vertebral column integrity with direct radiography were determined.

Remodelling of the spinal canal after burst fracture. A prospective study of two cases
, 1988 Two cases of burst fracture of the upper lumbar spine are reported. In both cases the narrowing of the spinal canal shown by CT scans was progressively relieved by natural remodelling.

Advanced Science, EarlyView.A sandwich‐structured aramid composite paper was designed to integrate high corona resistance and thermal conductivity. The fluorinated graphene/aramid surface layers effectively dissipate space charges to suppress corona discharge. Meanwhile, the boron nitride nanotube/aramid core layer constructs continuous heat‐conduction pathways.

Advanced Science, EarlyView.Inspired by the insect campaniform sensillum, a heterogeneous bilayer strain sensor is developed based on a unique impedance mismatch and three‐dimensional structural dynamic percolation strategy. The sensor enables real‐time multi‐joint teleoperation of three joints and the gripper using a six‐degree‐of‐freedom robotic‐arm platform.
