Effect of Low-Temperature Plasma Jet on Thermal Stability and Physical Structure of Type I Collagen
This work is devoted to the characterization of type I collagen treated by a low-temperature plasma jet generated in ambient air to determine whether the resulting fibrous material is structurally preserved or reinforced. The physical structure of collagen is checked by differential scanning calorimetry (DSC), which is a well suited technique to analyze thermal transitions in proteins, such as denaturation. DSC is used to evaluate the thermal stability of collagen after the plasma treatments while Fourier transform infra red spectroscopy is used to check the integrity of triple helical domain and to investigate the effects of plasma treatments on the functional groups of collagen. It is more particularly shown that the plasma treatment can stabilize the collagen structure without altering the triple helical structure. This observation is supported by 1) the shift observed toward high-temperature range of the collagen denaturation and 2) the stiffening of the chains by a cross-linking action when compared to the control sample
Study of Formation and Decay of Rare-Gas Excimers by Laser- Induced Fluorescence
The aim of this chapter is to review the experimental and numerical techniques for the estimation of the laser-induced fluorescence (LIF) decay in rare gases using time-correlated single-photon counting. The advantages of single-photon counting technique are discussed by means of measurement uncertainty analysis. In addition, this chapter provides information concerning the application of this technique to filamentary dielectric barrier discharges (DBD) and radiation trapping of the resonant transitions

Formation of N
The emission spectrum of nitrogen and of mixtures of nitrogen with noble gases (Ar, He) was studied and relative vibrational intensities of the nitrogen first positive (N2 1+) system (N2(B, vâČ)âââN2(A, vâČâČ)â+âhÎœ) recorded between 570 and 1040 nm in the afterglow of a flowing microwave discharge at 8 Torr. In this region, N2(B, vâČ) relative populations were deduced from the recorded spectra and absolute N-atom concentrations measured by NO titration. Absolute N-atom densities were also obtained by TALIF, showing a good agreement between the two diagnostic methods. From this data, rate coefficients for the N-atom recombination in specific N2(B, vâČ) vibronic levels were obtained in N2 and in mixtures of N2 with Ar or He. Additionally, concentrations of N2(A), N2(X, vâ=â12â13) molecules and of N2+ ions were also deduced from band intensity ratios in the transition region between the pink and the late afterglows
Positive effects of hypoxic preconditioning of the extracellular matrix and stromal vascular fraction from adipose tissue
Background: Numerous approaches have been developed to decelerate the aging process of facial skin. Synthetic fillers and cell-enriched fat grafts are the main procedures employed to fill wrinkles. Objective: The aim of this study was to evaluate the in vitro and in vivo safety and efficiency of a new process developed by SYMBIOKEN: the AmeaCell, which facilitates the extraction of the stromal vascular fraction (SVF) and the associated hypoxia pre-conditioned matrix to promote fat graft survival. Methods: The AmeaCell device allows the extraction from adipose tissue of SVF and pre-conditioned MatriCS and promotes a hypoxic environment. Experiments were carried out on human cells and then in mice. Results: Characterization of cells and MatriCS showed that after their extraction using the new process developed by SYMBIOKEN, the extracted cells expressed stem-cell markers. The presence of characteristic proteins and lipid fractions found in the adipose matrix were confirmed in MatriCS. Cobalt chloride treatment of the matrix using the AmeaCell device induced modifications in the matrix composition with a decrease in laminin and without collagen modification, both of which promote adhesion and differentiation of SVF or adipose-derived stromal cells. The combination of MatriCS and SVF (1Â ĂÂ 106 and 5Â ĂÂ 106, respectively) is safe and efficient to fill winkles induced by UVB irradiation. The cross-talk between MatriCS and SVF can act a durable filler compared to the filling performed using cells or matrix or fat alone, which need to be replaced frequently. Conclusion: These results indicate that the combination of MatriCS and SVF is safe and effective as a biological filler for achieving skin rejuvenation and wrinkle filling
