Abstract: introduction: resistance to macrolides, lincosamides and streptogramins b (mlsb antibiotics) in staphylococci may be due to modification in ribosomal target methylase encoded by erm genes. the expression of mlsb resistance lead to three phenotypes, namely constitutive resistance (cmlsb), inducible resistance (imlsb), and resistance only to macrolides and streptogramins b (msb). the imlsb resistance is the most difficult to detect in the clinical laboratory. objective: this study investigated the expression of mlsb resistance and the prevalence of the erm genes among 152 clinical isolates of staphylococcus aureus and coagulase-negative staphylococcus (cns) from hospital de clínicas de porto alegre. methods: primary mlsb resistance was detected by the disk diffusion method. isolates with imlsb phenotype were tested by double-disk induction method. all isolates were tested by a genotypic assay, pcr with specific primers. results: a total of 46.7% of staphylococci were positive for cmlsb; 3.3% for imlsb and 3.3% for msb. one or more erm genes were present in 50.1% of isolates. the gene erma was detected in 49 isolates, ermc in 29 and ermb in 3. conclusion: the prevalence of the erma, ermb and ermc genes were 29.6%, 17.1% and 0.66% respectively, and constitutive resistance was the most frequent as compared to the other two phenotypes.

Abstract: O Herpesvírus Humano Tipo 8 (HHV-8) ou Herpesvírus associado ao Sarcoma de Kaposi (KSHV) é conhecido como o agente causador do Sarcoma de Kaposi (SK). O contato sexual entre homens é uma importante via de transmiss o do HHV-8, pois esse é o principal fator de risco de contágio em pacientes soropositivos para HIV. Em algumas regi es da áfrica onde o SK tem sido evidenciado em crian as, mesmo depois da descoberta da Síndrome da Imunodeficiência Adquirida (AIDS), outras rotas de transmiss o também têm sido discutidas.

Abstract: In this research, we highlight the hypermodern individual, the ways he lives in the contemporary world and the psychosocial determinants involved in illness. We aim to reveal the impact of traumatic life events and the senses and meanings given by the patients to their pathologies. The research was carried out at two private hospitals in Brazil, in the years 2010 and 2011. The study is based on a qualitative method, through a semistructured interview with open-ended questions and the drawings-stories procedure, in an intentional sample, closed by saturation, during the period of hospitalization and right after leaving hospital (15 to 30 days). We used a qualitative content analysis and analysis of drawings under the framework of Analytical Psychology. Seven female patients that underwent surgery were the subjects of this research: two with Myocardial Infarction, one with Takotsubo Syndrome, three with Breast Cancer and one with both pathologies. Through the analysis of the interviews and the symbols presented in the drawings, we observed demands for hyperformance and hyperfection, linked with illness, when in excess. Traumatic life events, job stress, reactions to loss, and death of loved ones without the possibility of psychological elaboration may cause fragility and a lowering of the capacity of the immune system to react, causing damage to health. Through the symbolic trajectory of life, spontaneously presented in the drawings, we observed the three types of thinking in the structure of the psiqué which formed the basis for mental equilibrium: rational, symbolic and mythological. Infarction and breast cancer cause different impacts on women’s lives. Knowing how to deal with stressful events and being conscious of the meanings given to illness may contribute to making a better or worse experience in life. Such knowledge may be crucial for both primary and secondary prevention.
Individuation and the Feminine Soul: Study of Feminine Archetypal Images Carried out on Surgical Patients  [PDF]

Abstract: This article is the result of a research carried out in a private hospital of Belo Horizonte, Brazil. The patient care model of the Mastology Department includes an interdisciplinary staff that aims for the comprehensive treatment of these surgical patients. The research is based on clinical approach, under the framework of Analytical Psychology. Feminine archetypal images are symbolically represented by the Main Goddesses of the Olympus. It is natural for one of these expressions to prevail throughout a woman’s life, or even in specific moments of her life, but it is important to recognize that all of them are part of the feminine soul. We can, therefore, define and understand the Goddesses from Greek Mythology symbolically as being representative of the various feminine psychogenic forces that are projected. In reality, they are internal images that can be used to help know and understand personal issues and changes that are necessary in a woman’s life, enabling personal growth and the possibility to identify herself with the more authentic elements of her being. In this work experience, the feminine force showed itself to be a force of creation, of expression and of overcoming.

Abstract: Increases in greenhouse gases (GHG) emissions, upon changes in land use and agricultural management, lead to a search for techniques that enhance carbon residence time in soil. Pyrolysis increases the recalcitrance of organic materials and enhances their activities as physical, chemical and biological soil conditioners. Emissions of CO2, CH4 and N2O quantified from a sandy soil that was treated with three rates (12.5, 25 e 50 Mg·ha-1) of either non-pyrolysed poultry manure and sugarcane straw or biochars, pyrolysed at two contrasting temperatures (350°C and 650°C). Subsequently, the flux of the three gases was converted and compared in a standard unit (CO2eq). The added biochars, significantly reduced GHG emissions, especially CO2, relative to the non-pyrolysed materials. The greatest differences between applied rates of poultry manure, relative sugarcane straw, both to biochar and raw material, and the positive response to the increase of pyrolysis temperture, confirm the importance of raw material choice for biochar production, with recalcitrance being an important initial characteristic. Greater emissions occurred with intermediate rate of biochars (25 Mg·ha-1) amendment to the soil. These intermediate rates had higher microbial biomass, provided by an intermediate C/N ratio derived from the original soil and the biochar, promoting combined levels of labile C and oxygen availability, leading to an optimal environment for microbiota.

Abstract: AIM: The population biology of the freshwater shrimp Macrobrachium jelskii was investigated here emphasizing the length-frequency distribution, sex ratio, reproductive period and juvenile recruitment. In addition, the abundance of individuals was correlated with the abiotic factors. METHODS: Samples were collected on a monthly basis from July 2005 to June 2007 along the river margin in shallow water of Grande River, at Planura region, State of Minas Gerais, Brazil (20o 09' S and 48o 40' W), using a trawl net (1.0 mm mesh size, and 2.0 m × 0.5 m wide). The fishing gear was handled by two people along the marginal vegetation of the Grande River in a course of 100 m, covered for one hour. In the laboratory, the specimens were identified, measured and sexed. RESULTS: A total of 2,789 specimens was analyzed, which corresponded to 1,126 males (549 juveniles and 577 adults) and 1,663 females (1,093 juveniles, 423 adults non-ovigerous and 147 ovigerous). The sex ratio differed significantly in favor of the females of M. jelskii (1:1.48; χ2 = 103.95; p < 0.0001). The mean size of carapace length (CL) of females (6.32 ± 1.84 mm CL) was statistically higher than of males (5.50 ± 1.07 mm CL) (p < 0.001). The length-frequency distribution of the specimens revealed an unimodal pattern and non-normal distribution for males and females (W = 0.945; p < 0.01). No significant relationship between the abundance of M. jelskii and the environmental variables was observed (p = 0.799). CONCLUSION: The presence of ovigerous females and juveniles in the population suggests a continuous reproduction pattern and recruitment for M. jelskii at Planura region. OBJETIVO: A biologia populacional do camar o de água doce Macrobrachium jelskii foi investigada, com ênfase na distribui o de frequência em classes de tamanho, raz o sexual, período reprodutivo e recrutamento juvenil.

Contudo, a preocupa o atual n o se limita apenas com a qualidade e quantidade da água, mas também, com os fatores que as ocasionam. O monitoramento dos recursos hídricos geralmente é uma tarefa morosa e onerosa. Uma técnica que tem demonstrado grande eficiência nestes estudos, com custo relativamente baixo, é o sensoriamento remoto. Nesse estudo, uma série de imagens Landsat5-TM é utilizada na análise da varia o da lamina d’água da lagoa de Parnaguá (PI). Conjuntamente, é verificado se há ou n o influência dos fen menos climáticos El Ni o e La Ni a nessa varia o. Os resultados mostram que existe correla o entre a varia o do espelho d’água da lagoa com os fen menos climáticos El Ni o e La Ni a, embora sejam necessários estudos que me am a utiliza o da água dessa lagoa para outros fins, tais como irriga o e uso doméstico.AbstractIt is known that water shortage can be a strong barrier to a region’s socioeconomic development. However, the current concern is not just with the quality and amount of the water, but also with their causing factors. The monitoring of hydric resources is usually a slow and onerous task. A technique that has shown great efficiency in these studies, with relatively low cost, is the remote sensing. In this study, a series of Landsat5-TM images is used to analyze the variation of the water level of the Parnaguá Pond (PI), Brazil. Jointly, it is verified whether the climatic phenomena El Ni o and La Ni a influence on that variation. The results show a correlation between the variations of the pond’s water surface and the climatic phenomena El Ni o and La Ni a, although it is necessary to carry on further studies to measure the use of the pond’s water for other ends, such as irrigation and domestic use.
