Composição química e toxicidade de óleos essenciais para o pulgão-verde Schizaphis graminum (Rondani, 1852)

Este trabalho teve como objetivo identificar e quantificar os constituintes dos óleos essenciais de Illicum verum, Ageratum conyzoides, Piper hispidinervum e Ocotea odorifera, bem como avaliar a toxicidade para o pulgão-verde Schizaphis graminum. A qualificação dos constituintes foi realizada por meio de um cromatógrafo gasoso + espectrômetro de massas, e a quantificação, por um cromatógrafo gasoso + detector de ionização de chama, ambos com uma coluna DB5. O método de hidrodestilação promoveu um rendimento (p/p) de 3,81% para I. verum, 0,46% para A. conyzoides, 2,85% para P. hispidinervum e 0,68% para O. odorífera. Já os componentes majoritários foram: precoceno (87,0%) e (E)-cariofileno (7,1%) para A. conyzoides; (E)-anetol (90,4%), limoneno (2,6%) e metil-chavicol (1,3%) para I. verum; metil-eugenol (81,2%) e safrol (10,6%) para Ocotea odorífera; e safrol (82,5%) e α-terpinoleno (13,4%) para P. hispidinervum. Pelos testes de toxicidade aguda (24 horas) com folhas de sorgo ou papel-filtro contaminados, verificou-se que o óleo de A. conyzoides foi o mais tóxico para o pulgão, com CL50 de 7,13 e 7,08 µL óleo/cm2 respectivamente, seguido por O. odorifera com CL50 de 11,80 e 103,00 µL óleo/cm2 respectivamente; I. verum de 51,80 µL óleo/cm2 em ambos os substratos; e o menos tóxico foi o óleo essencial de P. hispidinervum, com CL50 de 62,50 e 143,00 µL óleo/cm2, respectivamente. Dessa maneira, sugere-se que o uso dos óleos essenciais pode representar uma nova ferramenta em programas de manejo integrado de pragas.

Inspeção de Precaução de Contato: relato de Experiência de uma Graduanda de Enfermagem Botucatu

Infections Related to Healthcare (IRAS) is a problem of worldwide concern, responsible for much morbidity and lethality. The incidence of IRAS associated with resistant microorganisms has increased worldwide. It is also known that the etiology of bacterial resistance is multifactorial, thus controlling the spread of resistant microorganisms requires the implementation of control measures that involve the performance of standard and contact precautions, plus the use of antimicrobials. To diagnose the problem as to the likely accession of the measures of infection control was prepared in a form to inspect the practices of the health staff acting with patients in contact precautions. The inspections had an educational and awareness, no punitive measures were taken to staff as warnings, suspensions or complains of a breach of ethics. If any irregularities were found, the professional standards of care countershaft contact and the nurse responsible for the head nurse or unit area were notified and counseled about the correct practice of isolation. While an undergraduate student initiated precautionary inspections of contact in order to verify the actual use of isolation measures, since the professionals were unaware of my active participation in the Committee on Infection Control. Facilities and difficulties were encountered in the process, and from the inspections was possible interventions to facilitate compliance with standards for isolation imposed by contact. Since the instrument has significantly improved adherence to contact isolation practices, the members of the Infection Control regulated inspections and intend to use it as a permanent method

Aplicação da descarga por barreira dielétrica (DBD) em diferentes frequências no tratamento de polipropileno

In this work, air dielectric barrier discharge (DBD) operating at two different frequencies (60 Hz and 17 kHz) was used to improve surface properties of polypropylene (PP). The changes in surface hydrophilicity were investigated by contact angle measurements. The modifications in chemical composition of PP surface were studied by X-ray photoelectron spectroscopy (XPS) and Fourier-transformed infrared spectroscopy (FTIR). The PP roughness were analyzed before and after the DBD treatment using atomic force microscopy (AFM). In order to compare the results obtained at different frequencies, the analyses are presented as a function of the deposited energy density. The results show that both DBD treatments led to formation of low-molecular weight oxidized material (LMWOM). It tends to agglomerate into small mounts on the surface, as shown by AFM analyses. These structures are weakly bounded to the surface and can be easily removed by rinsing in polar solvents. After washing the DBD-treated samples, the PP partially recovers its original wetting characteristics. This suggests that oxidation also occurred at deeper and more permanent levels on the PP samples. Comparing both DBD treatments, the 17 kHz process was found to be more efficient in introducing oxygen groups to the PP surface

(En)quadros estéticos (artísticos e clínicos) e seus efeitos sensíveis

Based on the aesthetic investigations of Freud, the work intends to bring joints between possible sensitive effects caused by contact / reception with works of art (having them here as “framed art”) and psychoanalytic clinical setting. The text is also concerned to show that the production of these striking effects, happens by the condition of these items (artistic and clinical) are under a frame and therefore conceptualized as aesthetic in this article arguments.

Biological compatibility of some types of endodontic calcium hydroxide and glass ionomer cements

The purpose of this work was to evaluate the biological compatibility of the Sealapex, Apexit, Sealer 26 and Ketac Endo endodontic cements. Polyethylene tubes containing these cements were implanted in the subcutaneous tissue of 40 (forty) rats. The animals were sacrificed after 14 and 90 days. A descriptive analysis of the reactions found in the connective tissue by contact with the cements was performed. The magnitude of inflammatory infiltrate, the presence and predominance of cell types and their distribution as to the filling material and reparative phenomena, such as fibroblastic and angioblastic proliferation and formation of fibrous capsules, were subjectively measured. After 90 days, all cements presented statistically significant reduction of the inflammatory reaction, presence of a fibrous tissue capsule in contact with the opening of the tubes containing the filling materials, and reduction of fibroblastic proliferation. Angioblastic proliferation decreased only for the Sealer 26 and Ketac Endo groups. All cements tested were either partially or totally phagocyted, and the mildest inflammatory response was found for the Sealer 26 group at both evaluation periods.
