For blood vessel tissue engineering, an ideal vascular graft should possess excellent biocompatibility and mechanical properties. For this study, a elastic material of poly (L-lactic acid-co-ε-caprolactone) (P(LLA-CL)), collagen and chitosan blended scaffold at different ratios were fabricated by electrospinning. Upon fabrication, the scaffolds were evaluated to determine the tensile strength, ...

The primary objective of this study was to determine which closure technique simple interrupted suture (SIS), simple continuous suture (SCS), interrupted double loop closure (IDLC) or continuous double loop closure (CDLC) results in stronger wound repair after midline laparotomy. Surgery was performed on 48 male rats. On the 5th postoperative day the rats were sacrificed and wound strength was ...

Coronal shocks are an important structure but without direct observations in solar and space physics. The strength of shocks plays a key role in shockrelated phenomena, such as radio bursts, SEP generation and so on. This paper will present an improved method of calculating Alfvén speed and shock strength near the Sun. In the method, observations as many as possible rather than onedimensional g...

A corrosion defect is recognized as one of the most severe phenomena for high-pressure pipelines, especially those served a long time. Finite-element method and empirical formulas are thereby used strength prediction such pipes with corrosion. However, it time-consuming finite-element there limited application range by using formulas. In order to improve strength, this paper investigates burst ...

Collagen and elastin networks contribute to highly specialized biomechanical responses in numerous tissues and species. Biomechanical properties such as modulus, elasticity, and strength ultimately affect tissue function and durability, as well as local cellular behavior. In the case of vascular bypass grafts, compliance at physiologic pressures is correlated with increased patency due to a red...

The near infrared (NIR) spectroscopy presents itself as an interesting non-destructive test tool as it enables a fast, simple and reliable way for characterizing large samplings of biological materials in a short period of time. This work aimed to establish multivariate models to estimate the crystallinity indices and tensile and burst strength of cellulosic and nanocellulosic films through NIR...

In vivo tissue engineering uses the body as a bioreactor for tissue regeneration, thus placing stringent requirements on tissue scaffolds, which should be mechanically robust for immediate implantation without a long in vitro cell culture time. In addition to mechanical strength, vascular grafts fabricated for in vivo tissue engineering approach must have matching mechanical properties to the t...

In recent years, concerns about environmental waste caused by petroleum-derived chemicals as well as the consumer's demand for high quality food products, have prompted people to pay more attention to developing biodegradable food packaging materials using natural resources such as cellulose fibers and chitin derivatives. In this study, chitin whiskers have been successfully generated by hydrol...
