Computational elements based on coupled VO oscillators via tunable thermal triggering.

Computational technologies based on coupled oscillators are of great interest for energy efficient computing. A key to developing such technologies is the tunable control of the interaction among oscillators which today is accomplished by additional electronic components. Here we show that the synchronization of closely spaced vanadium dioxide (VO) oscillators can be controlled via a simple thermal triggering element that itself is formed from VO.

Construction of a vascularized fascia-prosthesis compound model with axial pedicle for ear reconstruction surgery.

To design a vascular pedicled fascia-prosthesis compound model that can be used for ear reconstruction surgery. A vascularized tissue engineering chamber model was constructed in New Zealand rabbits, and fresh tissues were obtained after 4 weeks. The histomorphology and vascularization of the newly born tissue compound were analyzed and evaluated by tissue staining and Micro-CT scanning.

Experimental study of negative pressure wound therapy combined with platelet-rich fibrin for bone-exposed wounds.

To evaluate the efficacy of negative pressure wound therapy (NPWT) combined with platelet-rich fibrin (PRF) in treating bone-exposed wounds and explore its possible mechanism. A bone-exposed wound was created in a total of 32 healthy Sprague-Dawley rats, which were divided into either control group, NPWT group, PRF group or both (N + P group). The bone-exposed area, skin contraction rate and granulation coverage and the level of growth factors in granulation tissue were determined on days 4, 7 and 10.

Creating Cartilage in Tissue-Engineered Chamber Using Platelet-Rich Plasma Without Cell Culture.

Clinically available cartilage, such as large-volume tissue-engineered cartilage, is urgently required for various clinical applications. Tissue engineering chamber (TEC) models are a promising organ-level strategy for efficient enlargement of cells or tissues within the chamber. The conventional TEC technology is not suitable for cartilage culture, because it lacks the necessary chondrogenic growth factor, which is present in platelet-rich plasma (PRP).

[Study on the use of haemoglobin denaturation test as an alternative to Draize eye irritation test].

Objective: To use haemoglobin denaturation test (HD test) as an alternative to Draize eye irritation test (Draize test).

Methods: Fourteen cosmetic ingredients were tested by HD test. The results were compared with two kinds of scores in Draize test, i.

[Study on using the hen's egg test-chorioallantoic membrane as an alternative method of draize eye irritation test].

Objective: To establish and study the hen's egg test-chorioallantoic membrane (HET-CAM) as an alternative method of Draize eye irritation test (Draize test).

Methods: 14 cosmetic ingredients were tested by the Hen's egg test-chorioallantoic membrane score (HET-CAM score) and the chorioallantoic membrane-trypan blue staining (CAM-TB) methods.

Results: Showed that compared with two kinds of scores in Draize test, i.
