Highlights: • This study demonstrated the effect of ozonated Aloe vera oil in the healing of radiation dermatitis wound. • Groups that received no treatment was compared with groups that received treatment using 2.5% hydrocortisone ointment and ozonated Aloe vera. • Ozonated Aloe vera oil improves the healing of radiation dermatitis wound by increasing PDGF expression and epidermal thickness. Abstract : The long-term use of corticosteroids as a standard treatment for skin disorders, such as radiation dermatitis, can cause many side effects. Alternatively, ozonated Aloe vera oil may replace corticosteroids due to its fewer side effects and benefits in wound healing process. Re-epithelialization and the formation of growth factors, such as platelet-derived growth factor (PDGF), play an important role in the healing of dermatitis wound. This study intended to demonstrate the effect of ozonated Aloe vera oil to improve the healing of radiation dermatitis wound by increasing PDGF expression and epidermal thickness. This study used a post-test only control group design. A sample of 36 Sprague-Dawley rats was divided into 6 groups (C1=without treatment, C2=2.5% hydrocortisone ointment, P1=pure Aloe vera (AV), P2=300 mg/mL ozonated Aloe vera (OAV), P3=600 mg/mL OAV, P4=1200 mg/mL OAV. The expression of PDGF was assessed using Allred scoring with immunohistochemical staining, whereas the epidermal thickness was assessed using hematoxylin and eosin (H&E) staining at 400x microscopic magnification. The PDGF expression and epidermal thickness between the control and the treatment groups showed significant differences using a Kruskal-Wallis test (P=0.001) and one-way ANOVA test (P

The fabrication of a ZnO/Au nanosquare-array electrode was successfully carried out for the detection of glucose concentration in biomedical applications. The fabrication of the ZnO/Au nanosquare array using an ultra-thin alumina mask (UTAM) based on the imprinted anodic aluminum oxide (AAO) template and the direct current (DC) sputtering method was able to produce a very well-ordered nanosquare arrangement with a side size of 300 nm and a thickness of 100 nm. Tests were done to evaluate the performance of the electrode by means of cyclic voltammetry (CV) which showed that the addition of glucose oxidase (GOx) increased the sensitivity of the electrode up to 1180 ± 116 μA mM−1cm−2, compared with its sensitivity prior to the addition of GOx of 188.34 ± 18.70 mA mM−1 cm−2. A iox/ired ratio equal to ~1 between the peaks of redox reactions was obtained for high (hyperglycemia), normal, and low (hypoglycemia) levels of glucose. The ZnO/Au nanosquare-array electrode was 7.54% more sensitive than the ZnO/Au thin-film electrode. Furthermore, finite-difference time-domain (FDTD) simulations and theoretical calculations of the energy density of the electric and magnetic fields produced by the ZnO/Au electrode were carried out and compared to the results of CV. From the results of CV, FDTD simulation, and theoretical calculations, it was confirmed that the ZnO/Au nanosquare array possessed a significant optical absorption and that the quantum effect from the nanosquare array resulted in a higher sensitivity than the thin film.

The PDGF expression and epidermal thickness between the control and the treatment groups showed significant differences using a Kruskal-Wallis test (P=0.001) and one-way ANOVA test (P<0.001). The groups that was given ozonated Aloe vera oil had higher average of PDGF expression and thicker epidermis than the other groups. The Spearman's correlation test showed a strong positive relationship (p<0.001 and r=0.709) between the two variables. In conclusion, ozonated Aloe vera oil improves healing of radiation dermatitis wound by increasing PDGF expression and epidermal thickness. [ABSTRACT FROM AUTHOR]

Since the 1980's crucial advances in different basic and engineering sciences increasingly paved the way to a crossing-over between Engineering and Medicine, generating an unprecedent progress in the modern domain of biomedical research. These recent developments have finally established Biomedical Engineering as an autonomous branch of Engineering. This new branch of Engineering asserts itself in a variety of problems, namely, biomedical imaging, bioinformatics, biotechnology and genetics at the cellular and molecular levels, biomechanics, biomaterials and tissue Engineering, artificial organs, analysis of physiological signals and pattern recognition, and even management of health systems. With the beginning of the XXI, the important amount and quality of knowledge gathered, together with the motivation to boost even further possible technological and scientific developments, for social and economical reasons, layed the foundations for the first offers of university degrees, along with specialized post-graduations, in Biomedical Engineering. Naturally, the courses sustaining those newly born degrees provide a broad training, as a rule. Nonetheless, it is possible, even at the level of the Masters degree, defined within the current framework of the Bologna reform of high education in Europe, to give an advanced training, allowing the students to participate actively in the already on-going research of groups and institutes. In this article we present two cases of success, which reflect the significance and role of professional research in the training of a Biomedical Engineer. These two cases are studies performed by under-graduate students during the last six months (only) of their senior year. As an outcome, these studies bought innovative possibilities of diagnostic, within two very different areas: ultrasound 3D imaging of arteries and vision acuity related to optic aberrations.

The rapid development of microfluidic circuits and lab-on-chip devices for cell studies opened new perspectives for cellular biology, in particular for the biophysics and biomechanics of single cells. At the state of the art, a lot of attention is being paid to the possible integration of optical and acoustic actuators within microfluidic system because they both provide a contactless way for cell manipulation and analysis; additionally, they both offer other advantages such as rapid actuation, programmable capability and simple operation. In this work we exploit a microfluidic setup, combining optical and acoustic actuators, to perform cell mechanics characterization in terms of both cellular optical deformability (OD) and acoustic compressibility (AC). The OD and AC measurements reliability is obtained thanks to a precise determination of many parameters, as culture medium refractive index, viscosity and density, laser beam waist values and cell size, which are required for a proper estimation of cellular OD and AC. Cellular OD values are obtained by cell optical stretching procedure [1] while AC values are derived by fitting the cell acoustophoretic trajectory [2]. We apply this technique to measure the OD and AC of two human breast cancer cell populations, MCF7 and MDA, which are characterized by different metastatic potential. These two measurements are firstly performed separately and the results are reported in Fig.1. It can be seen that the two cell lines have similar cell size distribution, however, MDA shows both higher optical deformation and higher acoustic compressibility than MCF7, which is in good agreement with literature and can be associated with its elevated metastatic nature and stronger migratory ability. Afterwards, combined measurements of these two parameters were directly carried out on the same cell and it is found that there is no clear relationship between them in each cell sample, i.e., higher compressibility does not imply higher optical deformability [3]. Furthermore, we demonstrated that these two measurements do not affect each other. In conclusion, the chip presented here, together with the proposed measurement protocols, constitute a step forward in the characterization of cellular mechanical properties and thus in the possible identification of cells with specific biological properties. Additionally, we will present the experimental results of the currently on-going experiments showing the impact of drugs treatments on tumour-cells mechanical properties.

Biomedics ,Perfluorocarbon emulsion - Abstract
In this dissertation, the surface coating method/characteristics and a novel synthesis method for perfluorocarbon (PFC) emulsions were studied. These materials have relevance in a wide range of industrial and biomedical areas. Electrostatic coating of emulsions with poly-L-lysine (PLL) and chitosan (CS) was used to enhance the stability of the emulsions against phase separation. The ionic surfactant, 1,2-dioleoyl-sn-glycero-3-phosphate, DOPA, was used as an additive to the nonionic surfactant lecithin in order to increase the surface charge of the emulsion surface and facilitate accumulation of coating materials on the emulsion surface. Analysis of zeta potential versus pH was used to establish the best conditions for the coating process. The particle size and zeta potential was used to follow the coating progress. To characterize the final product, colorimetric determination was used to measure the bound/unbound fraction of PLL and CS and this was compared with a model-based analysis of zeta potential as a function of coating. Through this comparison and accounting for experimental error, a discrepancy in the effective particle number was revealed that was interpreted in terms of the compression and expansion of coating molecules on the surface as it assembles. Fluorescence quenching measurements using pyrene and fluorescein-doped emulsions supported the compression/expansion concept, resulting in more quenching when expansion of the coating took place. Thermodynamic analysis also supported these conformation changes and indicated a lowering of surface free energy for expanded coating. The second part of the dissertation reports a novel cosolvent method to synthesize PFOB emulsion with high yield production, in contrast to traditional extrusion methods that generate a large amount of water-filled liposomes as a side product. It was found that the selection of best cosolvent is related to its polarity relative to that of perfluorooctyl bromide (PFOB). Fourier transform infrared spectroscopy (FTIR) analyses were used to measure the retention of PFOB and revealed that nonpolar hexane has the best PFOB retention ability compared to methanol, ethanol, and chloroform. Moreover, phase transition temperatures (PTT) of the hexane/PFOB/lecithin system were observed at 13~19 °C and 22~24 °C by monitoring both the change in transparency by UV-Vis spectrophotometry and PFOB retention by FTIR. If emulsions are produced above the PTT (at 30 oC), PFOB is not retained. Quantitative measurement using FTIR for the best conditions gave 72% PFOB retention using the cosolvent method. Fluorescent and density analysis by centrifugation indicated that the traditional method for emulsion synthesis (directly emulsified) produced significantly more low-density water-filled liposomes than the cosolvent method. Higher density PFOB emulsion made with the cosolvent method can be easily separated and concentrated by centrifugation. The image of emulsions made by the traditional and cosolvent method could be viewed by cryogenic transmission electron microscopy.
