Shape-controlled synthesis of micro-/nanosized Cu particles with spherical and polyhedral shapes using the polyol process.

This study reports the synthesis of Cu micro-/nanosized particles through the polyol process. Cu particles were synthesized by reducing copper(ii) chloride in ethylene glycol (EG), polyvinylpyrrolidone (PVP), and potassium bromide (KBr) at low temperatures with or without the use of sodium borohydride (NaBH).

Characteristics of Ag-incorporated bioactive glasses prepared by a modified sol-gel method with a shortened synthesis time and without the use of catalysts.

This work presents the preparation of bioactive glasses 70SiO-(26 - )CaO-4PO-AgO (with = 0, 1, 3, 10 mol%) by a modified sol-gel method with reduced synthesis time based on hydrothermal reaction in a medium without acid or base catalysts. The synthetic materials were characterized by several physical-chemical techniques such as TG-DSC, XRD, SEM, TEM, and N adsorption/desorption measurement. The analysis data confirmed that the glass sample not containing Ag has a completely amorphous structure, while glass samples containing Ag exhibited a pure phase of metallic nano-silver in the glass amorphous phase.

One-stage reconstruction of the massive overlying skin and Achilles tendon defects using a free chimeric anterolateral thigh flap with fascia lata.

Background: Treatment for large defects in the non-weight-bearing Achilles tendon and soft tissues remains a reconstructive challenge. The free composite anterolateral thigh flap (ALT) with fascia lata (FL) has been indicated in the single-stage reconstruction of the Achilles tendon and soft tissue defect and this technique remain some disadvantages, such as the inability to perform primary flap thinning, requiring secondary flap thinning, and the delayed normalization of the range of motion of the ankle joint. The free chimeric ALT flap with FL was introduced as a novel alternative with many advantages in reconstructing the Achilles tendon and soft tissue defects.

Evaluation of Bite Force After Treatment of Le Fort Fractures by Internal Fixation and Mandibulomaxillary Fixation.

Objectives: Evaluation of bite force one, two, and four weeks after discharge following treatment of Le Fort I and/or Le Fort II fracture by rigid fixation and mandibulomaxillary fixation.

Objective: The aim of this study was to evaluate bite force following treatment of Le Fort I and/or Le Fort II fractures by rigid fixation and mandibulomaxillary fixation at one, two, and four weeks after discharge. This provides valuable results to guide the development of a treatment protocol for Le Fort fractures.
