Ana Beatriz Almeida de Oliveira, Ana Carolina Ritter, Eduardo Cesar Tondo, Marisa Itapema Cardoso
Food and Nutrition Sciences (FNS) , 2012, DOI: 10.4236/fns.2012.31006
Abstract: Different protocols have been used for washing and disinfecting leafy vegetables in Brazilian food services, however its effect on microbial reduction was barely studied. The aim of this study was to evaluate the effectiveness of lettuce washing and disinfecting protocols used by food services. The treatments evaluated were: washing in potable tap water (T1); washing and dipping in potable tap water (T2); washing with potable tap water and dipping in a solution of sodium hypochlorite (200 ppm of free chlorine) for 15 min (T3); and 30 min (T4); washing with potable tap water and dipping in 2% vinegar solution (T5); and 20% vinegar solution (T6). After the treatments, the samples were microbiologically evaluated to measure bacterial reductions. The microbial counts showed that the mean total mesophile reductions were: 0.64 log for T1, 0.75 log for T2, 2.06 log for T3, 2.46 log for T4, 1.68 log for T5 and 1.72 log for T6, and the mean total coliform reductions were: 1.11 log for T1, 1.09 log for T2, 2.29 log for T3, 2.35 log for T4, 1.6 log for T5 and 2.09 log for T6. Based on these results it can be concluded that protocols which used 200 ppm sodium hypochlorite for 15 to 30 min (T3 e T4), were the most effective, followed by treatment with 20% vinegar solution (T6). The latter method, however, turned the lettuce dark during the distribution period.

Open Journal of Nursing (OJN) , 2015, DOI: 10.4236/ojn.2015.510095
Abstract: A quantitative descriptive study aimed to evaluate the physical structure accessibility of gynecological nursing clinics and their bathrooms in basic health units for users with motor disabilities. A checklist tool/instrument was applied for analyzing 16 items in the bathroom and four in the nursing clinic. 157 basic health units were evaluated. In the nursing clinic, counters and tables (79.6%) were accessible, but stretchers (93%), seats (93.6%) and doors (87.3%) were inaccessible; moreover, 17.8% of the units examined proved totally inaccessible. In the bathroom, the items with the best evaluation were the height of the toilet flusher (47%) with operation by slight pressure (44.6%) and the wall-mounted sink (42.7%). Bathroom doors and turning area/space for wheelchairs were inaccessible. No bathroom reached full accessibility, and 31.2% were entirely inaccessible. Non-compliance was evident of the standard 9050:2004 of the Brazilian Association of Technical Standards. Raising the awareness of health and engineering professionals is recommended to learn technical accessibility standards and implement them.

Abstract: it was investigated the effect of the growth stage of rescued embryos on plant obtention from crosses between seedless grape parents. two methods for in vitro culture were compared. method 1 (m1): seed traces were cultured 60 days in er culture medium. method 2 (m2): procedure of m1 followed by additional 30 days in ms culture medium. the stage of embryo growth was established at the end of this period, when the embryos were rescued and transfered to wp culture medium. four classes of embryo stages were indentified: globular, heart, torpedo and undefined. the globular stage, the most frequently found, produced the largest quantity of recovered plants, though it had the lowest capacity of originating plants. the torpedo stage was the most efficient in producing plants. m2 promoted the largest amount of germinated embryos and recovered plants. as the embryo growth stage affects the plant obtention, the rescue of embryos in an advanced growth stage promotes a higher capacity of producing plants. therefore the use of techniques that favour the rescuing of embryos in an advanced growth stage can increase the obtention of plants.

Abstract: Pesquisou-se o efeito do estádio de desenvolvimento de embri es resgatados na obten o de plantas em cruzamentos entre genitores apirenos de videira, utilizando dois métodos de cultivo in vitro de sementes-tra o. No método 1 (M1), as sementes-tra o foram cultivadas 60 dias em meio-de-cultura ER e no método 2 (M2) 60 dias em ER, mais 30 dias em meio-de-cultura MS. O estádio de desenvolvimento do embri o foi identificado no final destes períodos, quando do resgate e transferência para meio-de-cultura WP. Quatro tipos de embri es foram identificados: globular, cordiforme, torpedo e indefinido. O estádio globular foi encontrado com maior freqüência, levando à obten o de maior número de plantas, mesmo tendo apresentado menor capacidade de gerar plantas. A maior eficiência em gerar plantas foi obtida com o estádio torpedo. No M2, ocorreu maior número de embri es germinados e de plantas desenvolvidas. Como o estádio de desenvolvimento do embri o influencia na obten o de plantas, o resgate de embri es em estádio mais avan ado do seu desenvolvimento leva a tem maior capacidade de gerar plantas. Portanto, uso de técnicas que favore am o resgate de embri es mais desenvolvidos pode aumentar o número de plantas obtidas.

Abstract: The aim of the present study is to demonstrate the anxiolytic and anticonvulsant effects of a hydroalcoholic extract obtained from the aerial parts of Cissus sicyoides L. (CS) (Vitaceae) on male and female mice using several behavioral assays. Groups of males and females treated via intraperitoneal (IP) with doses of 300, 600, and 1000 mg/kg of the extract showed significant action in the elevated plus-maze (EPM), time spent in the open arms, and number of entries in the open arms. The board-hole test also showed a significant increase in the time spent in head-dipping and in marble-burying test of the number of marbles buried. The same treatment increased the duration of sleeping time induced by sodium pentobarbital and also showed a significant increase in protection against pentylenotetrazole-induced convulsions. These results indicate an anxiolytic and anticonvulsant-like action from C. sicyoides L. extract on mice, probably due to the action of flavonoid(s), Linalool, and -tocopherol present in the C. sicyoides leaves.

Abstract: The aim of this study was to evaluate the effects of silver nitrate in the in vitro development and conservation of passion fruit plants. Experiments were carried out at the Laboratory of Culture and Tissues, in the National Cassava and Fruits Research Center (EMBRAPA), using microcuttings of Passiflora gibertii N. E. Br., previously cultivated in vitro. The microcuttings were placed in MS media supplemented with silver nitrate at concentrations of 0, 1, 2, 4 and 8 mg·L-1, and, during 30, 60 and 90 days, the following variables were identified: Shooting length (cm), number of roots, number and coloration of leaves. A completely randomized design with 30 replications in a split-plot scheme was employed. Polynomial regression equations were adjusted in analysis of variance to compare averages of treatments. The obtained results support the assumption of high sensitivity of passion fruit tissues to ethylene, which reflects in the lost of vigor and in the induction of culture senescence by its accumulation. Based on obtained results, and in order to mitigate this problem, it is possible to indicate an addition of 2 mg·L-1?of silver nitrate in culture media, for the micropropagation of passion fruit plant, allowing the controlling of the atmosphere inside the culture test tubes, during the establishment of explants and other steps of the process.

Abstract: based on fragments of the clinical case of an autistic child, this paper intends to question the psychoanalytic knowledge, in particular, the concepts of language, significant and object. in this case study, the direction of the treatment took place in accordance to the analyst's listening of the "verbal elements" presented by the patient, which resulted, during the sessions, in the construction of a particular "verbal term". the hypothesis supported is that this term has operated, in the course of treatment, as something similar to a "privileged significant" as formulated by lacan (1985[1972-1973]). this specific term was articulated by the patient, according to her own know-how towards the language, not without a place of jouissance modalization, opening the possibility of the emergence of the look, with the construction of the edges of the body.

Abstract: Peptic ulcer disease is a deep gastrointestinal erosion disorder that involves the entire mucosal thickness and can even penetrate the muscular mucosa. Numerous natural products have been evaluated as therapeutics for the treatment of a variety of diseases, including this one. These products usually derive from plant and animal sources that contain active constituents such as alkaloids, flavonoids, terpenoids, tannins and others. The alkaloids are natural nitrogen-containing secondary metabolites mostly derived from amino acids and found in about 20% of plants. There has been considerable pharmacological research into the antiulcer activity of these compounds. In this work we review the literature on alkaloids with antiulcer activity, which covers about sixty-one alkaloids, fifty-five of which have activity against this disease when induced in animals.

Abstract: streptococcus agalactiae isolates are more common among pregnant women, neonates and nonpregnant adults with underlying diseases compared to other demographic groups. in this study, we evaluate the genetic and phenotypic diversity in s. agalactiae strains from rio de janeiro (rj) that were isolated from asymptomatic carriers. we analysed these s. agalactiae strains using pulsed-field gel electrophoresis (pfge), serotyping and antimicrobial susceptibility testing, as well as by determining the macrolide resistance phenotype, and detecting the presence of the erma/b, mefa/e and lnub genes. the serotypes ia, ii, iii and v were the most prevalent serotypes observed. the 60 strains analysed were susceptible to penicillin, vancomycin and levofloxacin. resistance to clindamycin, chloramphenicol, erythromycin, rifampin and tetracycline was observed. among the erythromycin and/or clindamycin resistant strains, the erma, ermb and mefa/e genes were detected and the constitutive macrolides, lincosamides and streptogramin b-type resistance was the most prevalent phenotype observed. the lnub gene was not detected in any of the strains studied. we found 56 pfge electrophoretic profiles and only 22 of them were allocated in polymorphism patterns. this work presents data on the genetic diversity and prevalent capsular serotypes among rj isolates. approximately 85% of these strains came from pregnant women; therefore, these data may be helpful in developing future prophylaxis and treatment strategies for neonatal syndromes in rj.
