Abstract: Estudos recentes têm enfocado a cultura juvenil, entretanto há lacunas quanto aos desejos dos jovens. O presente estudo registra resultados de pesquisas do Observatório de Juventudes, Cultura de Paz e Violências na Escola – OBJUVE da Universidade Federal do Piauí, especificamente sobre as práticas dos grupos de Hip Hop Vida na Periferia “Vida P” e Movimento pela Paz na Periferia “MP 3” e outra pesquisa sobre “Juventudes, Mídias e Violências”, objetivando compreender as media es formativas na constru o das identidades das/os jovens envolvidas/os em práticas em tais práticas de sociabilidades. S o referências teóricas desse trabalho os estudos de Adad (2004), Fischer (2008), Catani e Gilioli (2008), Bomfim (2006), Sposito (2003) dentre outras, que foi operacionalizado por meio de observa o nos espa os onde se encontravam os sujeitos dessas pesquisas e de aplica o de questionário com perguntas abertas e fechadas. Como resultados podemos registrar que as identidades dos/as jovens da periferia de Teresina s o construídas em meio a grupos de amigos, dos movimentos de que participam e de colegas do espa o escolar através de atividades culturais específicas (cine-periferia, teatro, dan as etc.) mediadas por a es formativas planejadas. N o obstante essa forma o, os/as jovens sofrem forte influência de atrativos para consumo mercadológico via institui es midiáticas, além de refor arem práticas de violência. This article deals with the modus operandi of the egressed students of higher education, native from the rural area, with work experience in their childhood and that had access to the best courses at Vale do Acaraú University, Sobral, Ceará. The discussed autobiographical research was relevant bearing in mind that, in their life history, the personal and familiar strategies preponderated over the context of poverty, subsistence, since the childhood during the primary school teaching, the adolescence in the middle school, until the youth in the university. The main strategies verified in their narratives are related to the social capital (interpersonal relationships), the knowledge and values transmitted by the family. We can verify the urgency of public policies of inclusion in the higher education in order to suit a considerable demand of people that doesn’t have access to higher education, or have access, and with difficulty, continue studying and graduate, specially at UVA (Vale do Acaraú University) that, being a state university, doesn’t apply the new “democratic” policies of teaching in higher education, such as ENEM and PROUNI. The results of the

Abstract: Producing Brazilian Cerrado plants, especially ones endangered, is essential for your maintenance. In this way, fertilization is furthermore uncertain. Here, we demonstrate the impact of soil addition of nitrogen (N, 4.20, 18.90, 31.50, 44.10 and 59.85 mg·dm-3) and phosphorus (P, 9.56, 57.38, 95.62, 133.86 and 181.67 mg·dm-3) fertilizers levels on the development and on nutrients uptake by Jacaranda decurrens subsp. symmetrifoliolata (carobinha), species of the Brazilian Cerrado, in a long term pot trial. The N and P addition together increased plant height and N concentration in roots. N and P also increased the P concentration and content on the roots in young plants, but in the older plants, isolated effect of both was stronger than their combined action. The N addition promoted branching, production of dry leaves and dry xylopodium, contents of K, Ca and P on the leaves, and N content on the roots. However, the N reduced xylopodium diameter, leaf area, and Mg contents in the young plants, but increased them in the older plants. The P addition increased stem diameter and dry biomass, P concentration and N content on the leaves, Ca content on the roots and also reduced N concentration on the leaves. However, the P addition increased Mg concentration on the roots in the young plants and reduced it in the older plants. In general, N levels ranging between 25.69 - 38.85 mg·dm-3 and P levels between 84.39 - 109.23 mg·dm-3 promote more effectively the plant development. Thus, N and P fertilization can promote the aerial development of plant and a differential allocation of nutrients between the carobinha tissues.

Alves, Cláudia Maria Pereira;Teixeira, Maria do Carmo Borges;Martino, Maria Cristina De;
Jornal Brasileiro de Patologia e Medicina Laboratorial , 2010, DOI: 10.1590/S1676-24442010000300007
Abstract: introduction: chronic renal patients undergoing hemodialysis treatment have cardiovascular atherosclerotic disease as the main cause of death. inflammation and endothelial dysfunction are directly associated with atherosclerosis. furthermore, the infection resulting from hepatitis c virus, common among such patients, would be another worsening factor of the inflammatory state. increased levels of endothelial dysfunction markers are found in chronic renal disease and hepatitis c, which could be important markers of atherosclerosis among these subjects. objective: to compare endothelial activity in patients undergoing hemodialysis with and without hepatitis c. methodology: we selected 28 patients undergoing hemodialysis and classified them into two groups: 1-hcv(+): 18 patients (anti-hcv[+] and pcr[+]) and 2-hcv(-): 10 patients (anti-hcv[-]). before the first weekly dialysis, blood samples from both groups were collected for icam-1, vegf, alt and tap serum dosage. results: icam-1 levels were high in 60.71%. the highest levels were found in hcv(+) group, though not statistically significant (p = 0.2024). there was no correlation between icam-1 levels and the hemodialysis time or alt levels in any group. on the other hand, vegf levels were normal in 92.85%. only two patients hcv(+) had high levels. there was also no correlation between vegf levels and the dialysis time or alt levels. conclusion: patients undergoing hemodialysis have high endothelial lesion, nevertheless, the presence of hcv chronic infection did not prove to be an aggravating factor. this result may be due to the small number of patients, hence further analyses with a larger sample are required for definitive conclusions.
Burkholderia pseudomallei: a case report of a human infection in Ceará, Brazil
Miralles Iracema Sampaio,Maciel Maria do Carmo Alves,Angelo Maria Rozzelê Ferreira,Gondini Mirna Moura
Revista do Instituto de Medicina Tropical de S?o Paulo , 2004,
Abstract: Burkholderia pseudomallei has rarely been isolated from environmental and clinical specimens in South America, particularly, in Brazil. This report describes a case of melioidosis with fulminant sepsis in a 10 year old boy, from rural area, in Teju uoca, State of Ceará, Brazil. Blood samples were positive and, through the analysis of results from biochemical tests and of drugs susceptibility profile, identified this gram-negative bacillus as B. pseudomallei. The contamination source remains obscure in this case, as soil and water tanks samples submitted to microbiological analyses did not indicate the presence of B. pseudomallei.
Lysostaphin: A Staphylococcal Bacteriolysin with Potential Clinical Applications

Pharmaceuticals , 2010, DOI: 10.3390/ph3041139
Abstract: Lysostaphin is an antimicrobial agent belonging to a major class of antimicrobial peptides and proteins known as the bacteriocins. Bacteriocins are bacterial antimicrobial peptides which generally exhibit bactericidal activity against other bacteria. Bacteriocin production is a self-protection mechanism that helps the microorganisms to survive in their natural habitats. Bacteriocins are currently distributed into three main classes. Staphylococcins are bacteriocins produced by staphylococci, which are Gram-positive bacteria of medical and veterinary importance. Lysostaphin is the only class III staphylococcin described so far. It exhibits a high degree of antistaphylococcal bacteriolytic activity, being inactive against bacteria of all other genera. Infections caused by staphylococci continue to be a problem worldwide not only in healthcare environments but also in the community, requiring effective measures for controlling their spread. Since lysostaphin kills human and animal staphylococcal pathogens, it has potential biotechnological applications in the treatment of staphylococcal infections. In vitro and in vivo studies performed with lysostaphin have shown that this staphylococcin has potential to be used, solely or in combination with other antibacterial agents, to prevent or treat bacterial staphylococcal infectious diseases.

Abstract: in order to evaluate the effects of nightshade coexistence on processing tomato yield, hybrid heinz 9992, an experiment was carried out consisting of two sets of treatments: in the first set, the crop was kept weed free (60 thousands plants ha-1) from transplanting to 15; 30; 45; 60; 75; 90; 105 days and 120 (harvest) days after transplanting (dat); while in the second set, the crop was kept in competition with the nightshade from transplanting until the same dat described for the set of treatments. a randomized block design trial, with three replications and four-row plots was used. height, leaf area, and aerial part dry matter of nightshade was obtained out of 10-plant samples. nightshade leaf area increased until 75 days of tomato coexistence (1,588 dm2 plant-1); height until 60 days of coexistence (85 cm), and the leaf dry biomass until 120 days of coexistence (31.7 g plant-1). the highest (108.6 tons ha-1 or 87.6 % of total production) and lowest (14.2 tons ha-1 or 59%) ripe tomato yields were observed when the coexistence between tomato and nightshade occurred only in the first 15 days or in the whole crop cycle, respectively. in these treatments, the average ripe fruit weights were 58.7 and 38.0 g, respectively. each cm2 of increase in the nightshade leaf area caused a reduction of 0.04 tons ha-1 (r2 = 0.90) on the ripe tomato yield; each cm of increase in the nightshade height reduced the ripe tomato yield in 0.82 tons ha-1 (r2=0.78); and each gram of increase in the nightshade aerial part dry matter reduced the ripe tomato yield in 2.84 tons ha-1 (r2=0.97). the period before interference, allowing up to 5% reduction in tomato yield, was 27 dat; the total period for preventing interference was 46 dat; and the critical period for preventing interference was between 27 and 46 dat.
