A Novel 3D-Printed Device for Precise Percutaneous Placement of Cannulated Compression Screws in Human Femoral Neck Fractures.

Background: The aim of this study was to investigate the application of computer-aided design and 3D printing technology for percutaneous fixation of femoral neck fractures using cannulated compression screws.

Methods: Using computed tomography data, an individualized proximal femur model was created with a 3D printer. The reduction of the femoral neck fracture and the placement of the cannulated compression screws were simulated on a computer.

Fisetin inhibits liver cancer growth in a mouse model: Relation to dopamine receptor.

Fisetin (3,3',4',7-tetrahydroxyflavone), a natural abundant flavonoid, is produced in different vegetables and fruits. Fisetin has been reported to relate to various positive biological effects, including anti-proliferative, anticancer, anti-oxidative and neuroprotective effects. Dopamine receptors (DRs) belonging to G protein‑coupled receptor family, are known as the target of ~50% of all modern medicinal drugs.

Facile synthesis of three-dimensional Pt-Pd alloyed multipods with enhanced electrocatalytic activity and stability for ethylene glycol oxidation.

A facile one-pot solvothermal method was developed for the fabrication of well-defined three-dimensional highly branched Pt-Pd alloyed multipods, using ethylene glycol as a solvent and a reducing agent, along with N-methylimidazole as a structure-directing agent, without any seed, template, or surfactant. The as-prepared nanocrystals exhibited a relatively large electrochemically active surface area, improved electrocatalytic activity and superior stability for ethylene glycol oxidation in alkaline media, compared with commercial Pt black and Pd black, making them promising electrocatalysts in fuel cells.

Effect of the PA-MSHA vaccine on septic serum-induced inflammatory response.

Sepsis is defined as a complex clinical syndrome caused by a serious infection followed by an amplified and deregulated inflammatory response. The complex syndrome is associated with a high rate of morbidity and mortality, despite substantial clinical advances. A vaccine derived from the outer membrane proteins of the Gram-negative bacteria Pseudomonas aeruginosa (PA-MSHA) has been demonstrated to exhibit immune modulatory properties.
