Evaluation of collagen-elastin hybrid tissue engineered vascular constructs

Proceedings of the Second Joint 24th Annual Conference and the Annual Fall Meeting of the Biomedical Engineering Society] [Engineering in Medicine and Biology, 2002

Collagen-based tissue engineered replacements for small diameter blood vessels have been investigated for many years but typically lack the elasticity and tensile strength necessary for implantation. In this study, we have incorporated elastin with an organized structural architecture into tubular cell-seeded collagen constructs using two different reconstituted collagen sources. We evaluated the mechanical, chemical, and biological properties of these collagen-only ...

The purpose of this study is to characterize the effects of radiation on collagen and skin by thermally stimulated current (TSC) spectroscopy. X-rays, /spl beta/-rays and UV radiation have similar effects on the molecular mobility of dermal collagen and skin. They induce the decrease of magnitude of the intra and intermolecular mobilities.

A lognormal multiplicative cascade model for multifractal characterization of skin ultrasound images

2012 9th IEEE International Symposium on Biomedical Imaging (ISBI), 2012

Biological tissue characterization requires adequate models of the data. Research in ultrasound image modeling has mainly focused on statistical methods. Some authors have addressed the fractal properties of such images using fractional Brownian motion model. However, recent studies have shown that skin ultrasound signals have multifractal properties. This paper proposes a lognormal multiplicative cascade model to explain this multi-fractality. Experimental ...

  • Evaluation of collagen-elastin hybrid tissue engineered vascular constructs

    Collagen-based tissue engineered replacements for small diameter blood vessels have been investigated for many years but typically lack the elasticity and tensile strength necessary for implantation. In this study, we have incorporated elastin with an organized structural architecture into tubular cell-seeded collagen constructs using two different reconstituted collagen sources. We evaluated the mechanical, chemical, and biological properties of these collagen-only and collagen-elastin hybrid grafts. Gel compaction quantification and live/dead staining revealed that cells in all matrix combinations were viable and able to rapidly compact their surrounding matrix. Compared to controls, uniaxial tensile testing revealed an increase in ultimate tensile strength and linear modulus for elastin hybrid constructs and for constructs formed with bovine dermal type I collagen. Histological assessment showed the unique composite structure of the elastin hybrid construct as well as the cell and extracellular matrix organization in all constructs studied. A discussion of these findings and their importance to vascular tissue engineering is discussed.

X-rays, /spl beta/-rays and UV radiation have similar effects on the molecular mobility of dermal collagen and skin. They induce the decrease of magnitude of the intra and intermolecular mobilities. The restriction of the molecular movements can be explained by an increase of collagen cross links.

  • A lognormal multiplicative cascade model for multifractal characterization of skin ultrasound images

    Biological tissue characterization requires adequate models of the data. Research in ultrasound image modeling has mainly focused on statistical methods. Some authors have addressed the fractal properties of such images using fractional Brownian motion model. However, recent studies have shown that skin ultrasound signals have multifractal properties. This paper proposes a lognormal multiplicative cascade model to explain this multi-fractality. Experimental results on real images show the validity of the model supported by excellent KS tests. The parameters of the model are proposed as indicators to characterize underlying tissues. Successful application to distinguish melanoma from healthy dermis is presented.

  • A two-dimensional recruitment model for the skin

    In this paper a 2-dimensional recruitment model for a planar soft tissue is presented, able to compute the local collagen fibers displacement caused by the application of a concentrated force and to evaluate the damage of the elastin matrix and on the fibrous component. The model assumption is that the collagen fibers oppose to the force by means of geometrical modification and the generation of traction forces; the scratching of elastin would be driven by the orientation changes of the collagen fibers. With reference to the skin, a layer with thickness equal to 3 mm has been modeled. An applied force of 0.75 N preserve the fibrous component from rupture. This value is the limit value; beyond it the collagen fibers start to fail whereas the elastin matrix disrupts also for lower values. This recruitment model can provide information about the stress state surrounding wounds in the skin, which is of interest because of the role that the stress plays in the healing process.

  • The sternum as an electrical shield

    Introduction - The TASER®conducted electrical weapon (CEW) delivers electrical pulses that can temporarily incapacitate subjects. We analyzed the distribution of TASER CEW currents in tissues posterior to the sternum to understand the likelihood of triggering cardiac arrhythmias. We also assessed the electrical `shielding' effects of the sternum. Methods and Results - Finite element modeling (FEM) was used to approximate the current density and electric field strength in tissues around the sternum. We analyzed 2 CEW dart deployment scenarios: (a) both darts over the anterior aspect of the sternum; and (b) a CEW dart anterior to the sternum and the other over the abdomen. In both scenarios, the sternum provided significant attenuation of CEW currents. Particularly, both FEMs predicted that the residual electrical current or charge from CEWs would be insufficient to cause either cardiac capture or induction of ventricular fibrillation at locations where cardiac tissue would reside relative to the posterior aspect of the sternum. Conclusion - The sternum offers significant `shielding' effect and protects the tissues posterior to it against effects of electrical current flow from anteriorly- placed CEW electrodes.

  • Numerical simulation of transdermal transport through iontophoresis

    Iontophoresis is a transdermal drug transport technique in which the permeability of various drug molecules is enhanced by applying a direct electric current. In this paper, the distribution of metronidazole (MN) in epidermis and dexamethasone (Dex) in dermis are analyzed through numerical simulation of various transport conditions. Both 2D and 3D models are considered. The corticosteroid has higher diffusivity and electrical mobility than MN. The Dex model is more sensitive than the MN one to parameters variation, such as voltage, distance between electrodes, and sizes.

  • P1B-2 In-Vivo Exploration of the Mechanical Properties of Healthy and Pathological Human Dermis with 2D High Resolution Elastography

    This work was based on 2D high frequency elastography used to describe, quantitatively, the mechanical behavior of human dermis in vivo in terms of axial strain and lateral displacement. The experiment material was the combination of 2 devices. First, an extensiometer developed by LMARC laboratory for in-vivo skin applications using uniaxial stretching stress. Second, our 20 MHz real time sonographer, Dermcup 2020trade. Filtered and Staggered Strain Estimation algorithm (SSE + low-pass filtering), was used to produce elastograms. A temporal cumulative technique was applied and kinetics of the axial strain, epsiv(t), and lateral retraction were obtained for homogeneous ROIs in the dermis. Kinetic profiles were useful to study several characteristics: inter-individual variations, viscoelasticity and reproducibility. Results on pathological dermis were discussed in the conclusion

  • Fuzzy exposure model

    This paper presents a fuzzy exposure model which deals with the uncertainties involved in analysing prolonged (chronic) chemical exposure for humans in risk assessment. The imprecise input information for the exposure model is expressed as fuzzy sets using linguistic variables such as high, low and constant. The risk assessor can extend these fuzzy sets with respect to the data availability. The result obtained from the calculations is a fuzzy number that indicates the life average daily exposure (LADE) to human beings. A case study is illustrated to present the methodology.
