Comparison of DNA-extraction methods and Selective Enrichment broths on the detection of Salmonella Typhimurium in swine feces by polymerase chain reaction (PCR)
Freschi, Carla Roberta;Carvalho, Luiz Fernando de Oliveira e Silva;Oliveira, Celso José Bruno de;
Brazilian Journal of Microbiology , 2005, DOI: 10.1590/S1517-83822005000400011
Abstract: the aim of this study was to compare different dna-extraction methods and selective enrichment broths for their effectiveness to detect salmonella typhimurium in artificially inoculated swine feces samples (100 cfu/g) by polymerase chain reaction. after enrichment in rappaport-vassiliadis, selenite cystine or müller-kauffmann tetrathionate, aliquots were used for dna extraction by three different methods: boiling-centrifugation, phenol-chloroform and salting-out. aliquots of extracted dna were then used as template in pcr. the selective enrichment broths had no effect on the efficiency of pcr when boiling-centrifugation and salting-out were used. on the other hand, phenol-chloroform was superior (p<0.05) when combined to rappaport-vassiliadis. considering cost and efficiency parameters, we encourage the use of müller-kauffmann tetrathionate broth in combination with boiling-centrifugation dna-extraction procedure.

Development of Mathematical Models for the Analysis of Hepatitis Delta Virus Viral Dynamics
Bruno C. de Sousa,Celso Cunha
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0012512
Abstract: Mathematical models have shown to be extremely helpful in understanding the dynamics of different virus diseases, including hepatitis B. Hepatitis D virus (HDV) is a satellite virus of the hepatitis B virus (HBV). In the liver, production of new HDV virions depends on the presence of HBV. There are two ways in which HDV can occur in an individual: co-infection and super-infection. Co-infection occurs when an individual is simultaneously infected by HBV and HDV, while super-infection occurs in persons with an existing chronic HBV infection.

Abstract: background: the nitric oxide (no) synthesis blockade is characterized by an increase in the cardiac sympathetic activity and the physical training promotes the decrease in the sympathetic activity. objective: we investigated the effect of the no synthesis blockade on the autonomic cardiovascular control in rats submitted to aerobic exercises during a 10-week period. methods: male wistar rats were divided in four groups: control rats, treated with chow food and water ad libitum for 10 weeks (cr); control rats, treated with ng-nitro-l-arginine methyl ester (l-name) during the last week (crl); rats trained during 10 weeks on an electrical treadmill (tr); rats trained for 10 weeks and treated with l-name during the last week (trl). the autonomic cardiovascular control was investigated in all groups with the use of a double blockade with methylatropine and propranolol and analysis of variability. results: the crl and trl groups presented hypertension. the crl group presented tachycardia and predominance of the sympathetic tonus in heat rate (hr) measurement after the pharmacological autonomic blockade. the tr group presented bradycardia and lower intrinsic hr when compared to the others. the evaluation of the hr variability showed lower absolute and normalized values in the low frequency (lf) band in the crl group. on the other hand, the trl presented an increase in the lf band in absolute values. the analysis of variability of the systemic arterial pressure (sap) showed that the crl and trl groups presented higher values in the lf band. conclusion: the previous physical exercise prevented the deficit in the autonomic cardiac control induced by the treatment with l-name, but did not prevent the increase in the sap variability.

Abstract: practices of pre-harvest burning and the application of vinasse and n fertilizer are common in sugarcane cultivation. however, results of few long-term studies have been published. this study carried in sugarcane plantations of cruangi sugar mill, timbaúba, state of pernambuco, brazil, located in the semi-arid-wet transition region of the state aimed at studying the effects of vinasse (80 m3 ha-1) and nitrogen fertilizer (n - 80 kg ha-1) and two harvesting systems (with or without pre-harvest burning) on sugarcane yield and industrial parameters in a long-term study (1983 to 1999). the experiment was set up in a 2 x 2 x 2 factorial design in complete randomized blocks with four replicates and had two phases (1983 - 1992 and 1992 - 1999). nitrogen application negatively affected the technical characteristics of sugarcane, although the yield gain proportioned by this practice favoured the overall sugar yield and compensated the such negative effects. the application of vinasse and the maintenance of cane trash in the system had no consistent effect on the industrial sugarcane parameters, although once again there was an overall gain in sugar production due to the higher yields.

Abstract: objective: to evaluate the use of high-dose sequential chemotherapy in a brazilian population. methods: high-dose cyclophosphamide followed by autologous hematopoietic stem cell transplantation is an effective and feasible therapy for refractory/relapsed lymphomas; this regimen has never before been evaluated in a brazilian population. all patients (106 with high-grade non-hodgkin lymphoma and 77 with hodgkin's lymphoma) submitted to this treatment between 1998 and 2006 were analyzed. chemotherapy consisted of the sequential administration of high-dose cyclophosphamide (4 or 7 g/m2) and granulocyte-colony stimulating factor (300 μg/day), followed by peripheral blood progenitor cell harvesting, administration of etoposide (2g/m2) and methotrexate (8 g/m2 only for hodgkin's lymphoma) and autologous hematopoietic stem cell transplantation. results: at diagnosis, non-hodgkin lymphoma patients had a median age of 45 (range: 8-65) years old, 78% had diffuse large b-cell lymphoma and 83% had stage iii/iv disease. the hodgkin's lymphoma patients had a median age of 23 (range: 7-68) years old, 64.9% had the nodular sclerosis subtype and 65% had stage iii/iv disease. nine hodgkin's lymphoma patients (13%) and 10 (9%) non-hodgkin lymphoma patients had some kind of cardiac toxicity. the overall survival, disease-free survival and progression-free survival in hodgkin's lymphoma were 29%, 59% and 26%, respectively. in non-hodgkin lymphoma, these values were 40%, 49% and 31%, respectively. high-dose cyclophosphamide-related mortality was 10% for hodgkin's lymphoma and 5% for non-hodgkin lymphoma patients. high-dose cyclophosphamide dosing had no impact on toxicity or survival for both groups. conclusions: despite a greater prevalence of poor prognostic factors, our results are comparable to the literature. the incidence of secondary neoplasias is noteworthy. our study suggests that this approach is efficient and feasible, regardless of toxicity-related mortality.
Auditoria e sociedade: o diálogo necessário
Almeida, Bruno José Machado de;
Revista Contabilidade & Finan?as , 2004, DOI: 10.1590/S1519-70772004000100006
Abstract: society, which is mostly structured from a market economy perspective, demands for an audit with increasing interventions in the diagnosis of particular situations, such as: going-concern matters, reporting fraud and illegal acts, valuing organizational economy, efficiency and effectiveness. thus, the audit product, its nature and functions need to be clarified urgently so as to be able to give an adequate response to public expectations. actually, the range of auditing should be expanded in order to satisfy these demands, since it is expected to provides some degree of assurance, as well as a response to society's current problems. the ambiguous concept of auditing leads to confrontations between auditors and financial information users, resulting in frequent accusations that the former do not alert about organizational flaws, although they approve the financial statements.the dialogue between society and auditing needs to be reinforced, so as to reach a balance point between both.
Análise comparativa das filosofias de auditoria

Revista Contabilidade & Finan?as , 2005, DOI: 10.1590/S1519-70772005000100007
Abstract: we intend to analyze the conceptual structures, basic normative instructions and theoretical postulates on which auditing is based. thus, we present the bases of auditing established by mautz and sharaf, flint and lee. first, we study these conceptual structures and emphasize the most critical points, most of them related to the audit expectation gap. next, we analyze common and distinctive aspects. the comparison between the basic postulates gives rise to new boundaries, related to auditing theory and particularly to the aspect of social responsibility. as a matter of fact, after the emergence of the company's social responsibility and the social value of financial information, the social function of auditing appears with a view to monitoring and giving credit to the financial information reported by the company's administrations, thus assuming a major role in today's social context.

Abstract: the objective of this work was to compare nitrous oxide (n2o) emissions to the atmosphere with pig slurry application on soil under no-tillage (nt) and minimum tillage (mt). the experimental design was set as a completely randomized design with five replications. the treatments consisted of the application (40 m3 ha-1), or not, of pig slurry in nt and mt. the n2o emissions were measured in situ, after the slurry application, for 28 days. the n2o flux increased with the application of slurry and, only in 20% of the evaluations, they were greater in nt. nitrous oxide emissions were related to the increase of the water-filled pore space. amounts of n-n2o emitted in 28 days represented 0.20 and 0.25% of total n applied with slurry for nt and mt, respectively. results work show that pig slurry application in nt does not increase the accumulated n2o emission in relation to application in mt.

Abstract: The objective of this manuscript is to analyze relation involving the energy sector and socioeco-nomic growth and, then, contextualize the process of energy integration within the development policies in South America. The methodology considers data related to the world’s economy and energy consumption and energy integration policy in countries and regions; and, South America’s energy potential and the energy integration process. Results show that despite the political and institutional difficulties involving the process, energy integration can bring a lot of benefits for countries development. The process of energy integration in South America is divided in three moments, but in both periods the transnational energy projects were restricted, mostly, by a bi-lateral plan and the creation of physical links in a region. In the 21th century’s context, it should be noted Brazil’s participation which has been consolidated as a lead country in this process, and, also the IIRSA (Initiative for the Integration of Regional Infrastructure in South America, nowadays renamed as COSIPLAN) like the main initiative in energy integration in the continent, in a context where the projects are no longer limited to traditional economic blocs. Finally, we note a lack of consensus in defining a comprehensive model of integration and solving asymmetries both within countries and between them.
