This study investigated the protective effect of a Vitis vinifera L. grape skin extract (ACH09) on blood pressure, lipid profile, and oxidative status in spontaneously hypertensive rats (SHR). Systolic blood pressure (SBP), total cholesterol, triglyceride, and glucose levels, as well as oxidative damage and antioxidant activity in the plasma and kidney, were evaluated in four experimental groups: control Wistar rats (W-C) and SHR-C that received water, and Wistar rats and SHR treated with ACH09 (200 mg/kg/d) in drinking water for 12 weeks (W-ACH09 and SHR-ACH09, respectively). SBP increased in the SHR group compared with the W groups and the treatment with ACH09 prevented the development of hypertension. Plasma triglyceride and total cholesterol levels increased in SHR compared with W-C rats; these changes prevented by treatment with ACH09. Glucose levels did not differ between the groups. The SHR group had increased oxidative damage in plasma, as expressed by 2-thiobarbituric acid reactive substances (TBARS) levels, and this prevented by ACH09. Levels of TBARS in the kidneys were lower in the SHR-ACH09 group than in the SHR-C group. Further, ACH09 increased the superoxide dismutase activity in both the plasma and kidneys of both SHR and Wistar rats. These results suggest that ACH09 is protective against disruption of blood pressures, oxidant status, and lipid profile in SHR, and provide important evidence on the benefits of ACH09 on hypertension and associated cardiovascular complications.

The Use of Bituminous Subballast on Future High-Speed Lines in Spain: Structural Design and Economical Impact

Teixeira, P.F.,Ferreira, P.A.,Pita, A. Lopez,Casas, C.,Bachiller, A. The Korean Society for Railway 2009 International Journal of Railway Vol.2 No.1

The development of structural solutions for high-speed or very high-speed tracks that minimize total life cycle costs of the system is a key issue to improve the operational profitability of new investments. In opposition to conventional ballasted tracks, slab track solutions can be a cost-effective solution, but only in the cases where the benefits due to the increase in track availability and the reduction of track maintenance offsets its much higher construction costs. In the cases where such investment is not feasible, it is worth to evaluate possible structural improvements to ballasted track that allow reducing its maintenance needs without increasing too much its construction costs. This paper evaluates the design requirements and the impact of improving conventional high-speed ballasted tracks by using a bituminous subballast layer. It is divided into two main parts: first the design requirements of the structural solutions with bituminous subballast and its possible benefits on high-speed track deterioration, and secondly the evaluation of the economic impact, in terms of construction costs, of using this structural solution material in future Spanish high-speed lines.

Effect of Aminoglycoside Antibiotics on in-Vitro Morphogenesis from Cultured Cells of Chrysanthemum and Tobacco

Teixeira da Silva, Jaime A.,Fukai, Seiichi The Korean Society of Plant Biotechnology 2004 Plant molecular biology and biotechnology research Vol.6 No.1

Successful genetic transformation of plants requires non-chimeric selection of transformed tissues and their subsequent regeneration. With rare exceptions, most transformation protocols still rely heavily on antibiotics for selecting transgenic cells that contain an antibiotic-degrading selectable marker gene. Here, the morphogenic capacity of in-vitro explants of chrysanthemnum and tobacco stems and leaves (control and transgenic) changed with the addition of aminoglycoside antibiotics (AAs), In a test of 6 AAs, phytotoxicity occurred at concentrations of 10 to 25 and 50 to 100$\mu\textrm{g}$ $mL^{-1}$ in chrysanthemum and tobacco explants, respectively. Light conditions as well as explant source and size also had significant effects. The use of transverse thin cell layers (tTCLs), in conjunction with high initial AA selection levels, supported the greatest regeneration of transgenic material (adventitious shoots or callus) and the lowest number of escapes. Flow-cytometric analyses revealed no endodu-plication in chrysanthemum, even at high AA levels. However, this phenomenon was observed in tobacco calli(8C or more), even at low AA concentrations (i.e., 5 to 10 $\mu\textrm{g}$ mL$^{-1}$ ).

Prediction of Forming Limits Based on a Coupled Approach Between Anisotropic Damage and Necking Models

P. Teixeira,J.M.A. Cesar de Sa,A.D. Santos,F.M.A. Pires,A. Barata da Rocha 한국소성가공학회 2010 기타자료 Vol.2010 No.6

This article presents an integrated approach for localized necking and failure prediction in sheet metal forming processes, based on the coupling between the anisotropic damage evolution law proposed by Lemaitre [1] and the modified maximum force criterion (MMFC) proposed by Hora et al [2]. To illustrate the essential features of the coupled approach, an aluminum alloy has been selected and numerical predictions have been compared with experimental forming limits, obtained for both linear strain paths evolutions. Numerical results show that the introduction of the softening behavior, caused by the increase of damage, into the necking criterion can play a significant role in triggering local necking, providing an improved prediction of the necking occurrence together with the capability of performing calculations of limit strains when they are governed by fracture rather than by local necking.

Evaluation of Endophytic Colonization of Citrus sinensis and Catharanthus roseus Seedlings by Endophytic Bacteria

Paulo Teixeira Lacava,Welington Luiz Araujo,Joao Lucio Azevedo 한국미생물학회 2007 The journal of microbiology Vol.45 No.1

Over the last few years, the endophytic bacterial community associated with citrus has been studied as an important component interacting with Xylella fastidiosa, the causal agent of citrus variegated chlorosis(CVC). This bacterium may also colonize some model plants, such as Catharanthus roseus and Nicotiana clevelandii. In the present study, we compared the endophytic colonization of Citrus sinensis and Catharanthus roseus using the endophytic bacteria Klebsiella pneumoniae. We chose an appropriate strain, K. pneumoniae 342 (Kp342), labeled with the GFP gene. This strain was inoculated onto seedlings of C. sinensis and C. roseus. The isolation frequency was determined one week after the inoculation and the endophytic colonization of K. pneumoniae was observed using fluorescence microscopy. Although the endophytic bacterium was more frequently isolated from C. roseus than from C. sinensis, the colonization profiles for both host plants were similar, suggesting that C. roseus could be used as a model plant to study the interaction between endophytic bacteria and X. fastidiosa.

Background Breast augmentation with implants is the most commonly performed cosmetic plastic surgery in Brazil and worldwide. The aim of this study was to assess patient satisfaction and quality of life following subpectoral breast augmentation with either microtextured or macrotextured implants, using the BREAST-Q. Methods A prospective study was conducted with 40 women with hypomastia undergoing subpectoral breast augmentation. The patients were randomly allocated to two groups to receive either microtextured or macrotextured breast implants. All participants were assessed preoperatively (baseline) and after 2 and 4 months of surgery for quality of life and patient satisfaction with the surgical results, using the BREAST-Q augmentation module, a patient-reported outcome measure. Results The patients had amean age of 28.96.45 years. Themicrotextured (n¼20) and macrotextured (n¼20) groups were homogeneous for sex, age, education level, marital status, and number of children (p>0.05). Both groups showed significant improvement in satisfaction with breasts (p<0.001), psychosocial well-being (p<0.001), and sexual well-being (p<0.001) at the 2- and 4-month follow-up visits compared with baseline. The observed improvements were associated with high effect size values of 5.09, 3.44, and 3.90, respectively. In contrast, significant decreases from baseline in physical well-being scores (p¼0.001) were found 2 and 4 weeks after surgery in both groups. Conclusion Subpectoral breast augmentation with either microtextured or macrotextured breast implants improved satisfaction with breasts and quality of life in patients with hypomastia.

Analysis of the bacterial community in glassy-winged sharpshooter heads

Paulo Teixeira LACAVA,Jennifer PARKER,Fernando Dini ANDREOTE,Francisco DINI-ANDREOTE,José Luiz. RAMIREZ,Thomas A. MILLER 한국곤충학회 2007 Entomological Research Vol.37 No.4

The glassy-winged sharpshooter (GWSS), Homalodisca vitripennis, is an important vector of various strains of Xylella fastidiosa, which cause disease in a variety of economically important plants. These diseases include citrus variegated chlorosis, oleander leaf scorch and Pierce’'s Disease of grapevines. Symbiotic control (SC) is a new strategy that uses symbiotic endophytes as biological control agents to antagonize or displace the pathogenic strains of X. fastidiosa. Candidate endophytes for use in SC must occupy the xylem of host plants and attach to the pre-cibarium and cibarium of sharpshooter insects in order to have access to the pathogen. The study of the bacterial community of GWSS heads by isolation and denaturing gradient gel electrophoresis (DGGE) revealed the presence of species that may be suitable for use in SC. In addition, the results indicated that two important factors, insect age and choice of host plant, affect the composition of the bacterial community in GWSS heads. The main bacterial genera isolated as colonizers of GWSS heads were identified, using partial 16S rRNA gene sequencing, as Bacillus, Pseudomonas, Pedobacter and Methylobacterium, as well as the species Curtobacterium flaccumfaciens. DGGE patterns revealed a diversity of endophytic species able to colonize the GWSS head. The main genera isolated in culture were also identified using this technique. Principal component analysis (PCA) from polymerase chain reaction (PCR)-DGGE patterns indicated that the bacteria inhabiting the GWSS head are similar to those found as endophytes inside the host plants, and that insect developmental stage and preferential feeding on one host plant species over another are important factors in determining the composition of the bacterial community in the GWSS head. However, a shift in host plants for a small period of time did not cause changes in the compositions of these communities.
