Santos, Márcio Roberto Alves dos;
Varia Historia , 2008, DOI: 10.1590/S0104-87752008000200021
Abstract: the itineraries of quaresma delgado, explorer contracted by colonial authorities to investigate and map part of minas gerais and bahia "sert?o" in the 1730's, are studied as tipical accounts of reconnaissance, characteristic of a period when the exploration and mapping of the territory fortified themselves as illustrated scientific practices. the text - the account of reconnaissance - and the cartographic image - the map - produced by quaresma delgado are treated as constituent elements mutually complementary of a technical study, whose central aim is to describe, in a controlled language, the natural and human landscapes observed by the explorer.

Abstract: a parasitological survey was carried out among terena indians living in the tereré settlement in the municipality of sidrolandia, state of mato grosso do sul, brazil. single samples of feces from 313 indians were processed by means of the spontaneous sedimentation method. in the population studied, 73.5% were infected with at least one intestinal parasite or commensal. protozoa predominated. blastocystis hominis (40.9%), entamoeba coli (33.2%) and entamoeba histolytica/entamoeba dispar (31.6%) were the most common. bivariate analysis showed that females were generally more infected and presented higher rates of infection by entamoeba histolytica/entamoeba dispar and entamoeba coli. males were more infected by hookworms and strongyloides stercoralis than females. the precarious sanitary conditions of the tereré settlement are probably a contributory factor towards the high prevalence of intestinal protozoa.

Abstract: considering that most species of brazilian felids are threatened with extinction and poorly known, understanding their behavior is of special interest. this research aimed to create a behavioral catalog in captivity for the little spotted cat leopardus tigrinus, the smallest felid species from brazil. a male and a female were studied at the private collection of wild animals of klabin s.a. (telemaco borba, pr. -24o 12' s and 50o 33' w), in the mid tibagi region, east-central paraná state. from march to july, 2003, 40 hours of qualitative observations were carried out to define the categories and identify the behavior. the quantitative observations followed the focal animal method (altmann, 1974). they took place during three consecutive days and 11 observation periods (33 days), with 107.2 hours for the male and 42.4 hours for the female. each session lasted 15 minutes, and started at the beginning of each hour (from 06:00 am to 06:00 pm), with five-minute intervals between individual recording. the categories found were: moving (05 behavioral acts), still (06), body care (03), comfort (02), exploratory (04), marking (04), excretory (02), vocal (05), agonistic interactions (06), peaceful interactions (02), acts related to the acquisition of food (05) and reproductive acts (04). the catalog is a compilation of all behavioral acts of the species. there are many possibilities and perspectives for the use of this catalog. it could be an important tool to better understand the behavioral patterns and help the management and well being of the species in captivity.

Revista de Ciências Farmacêuticas Básica e Aplicada , 2010,
Abstract: Intera o medicamentosa é o resultado de uma interferência no efeito de um medicamento por outros agentes. Dentre os fatores que resultam nas intera es medicamentosas destacam-se a automedica o e a prática da polifarmácia. O objetivo deste trabalho foi realizar um levantamento de intera es medicamentosas que ocorrem com fármacos que atuam no sistema nervoso central, suas possíveis consequências, bem como os motivos que propiciam tal situa o. Foi realizado um estudo observacional transversal de 60 indivíduos da zona leste de S o Paulo que utilizam medicamentos psicotrópicos, maiores de 21 anos e de ambos os sexos, por meio de um questionário entre junho e agosto de 2008. Os principais psicotrópicos utilizados pelos indivíduos foram benzodiazepínicos e antidepressivos (54 indivíduos), sendo que estes fármacos apresentam alto índice de intera es medicamentosas. Cerca de 77% utilizam outros medicamentos em paralelo ao tratamento com psicotrópicos, sendo que destes apenas 35% o fazem com supervis o médica e 27% dos indivíduos utilizaram bebidas alcoólicas concomitantemente. As principais intera es encontradas envolveram antidepressivos com benzodiazepínicos, antiulcerogênicos, anticonvulsivantes e álcool. Conclui-se que a automedica o e o uso inadequado de medicamentos s o fatores que podem propiciar a ocorrência das intera es medicamentosas encontradas, algumas com consequências graves. Palavras-chave: Intera es de medicamentos. Intera es alimento-droga. Psicotrópicos. Assistência farmacêutica. ABSTRACT Possible drug interactions with psychotropics found in patients in East S o Paulo A drug interaction is the interference in the effect of a drug by another substance. Outstanding among the factors that result in drug interactions are selfmedication and the practice of polypharmacy. The aim of this work was to conduct a survey of drug interactions that occur with drugs that act on the central nervous system, their possible consequences and the reasons for their occurrence. An observational cross-sectional study was performed on 60 subjects from East Sao Paulo who take psychotropic drugs (over 21 years old and of both genders), by means of a questionnaire applied from June to August 2008. The main drugs taken by those interviewed were benzodiazepines and antidepressants (54 subjects), which are drugs that have high rates of drug interactions. About 77% took other drugs, in parallel with the psychotropic drug treatment, of which only 35% were under medical supervision, and 27% of subjects drank alcohol while taking psychotropic drugs. The main interac

Revista de Administra??o (S?o Paulo) , 2012, DOI: 10.5700/rausp1026
Abstract: the aim of this exploratory research study conducted in 2009, guided by an extensive review of the bibliography and by use of the case study method, was to identify the congruent elements between the strategic positioning of the brazilian subsidiary of a multinational and the business network of which it is a part. based on two specific models found in the academic literature on the aforementioned themes (strategic positioning and networks), the conclusions of this paper suggest that vertical demand-supply networks (moller and rajala, 2007) are suitable to implement the strategic positioning defined as best product in the delta model (hax and wilde ii, 1999; 2001).
Lipossarcoma de mediastino: relato de caso
Saad Junior, Roberto;Dorgan Neto, Vicente;Gon?alves, Roberto;Botter, Márcio;Siqueira, Leticia Cristina Dalledone;
Jornal Brasileiro de Pneumologia , 2008, DOI: 10.1590/S1806-37132008000100010
Abstract: here, we describe the case of a 51-year-old female with mediastinal liposarcoma. liposarcoma is the most common malignant mesenchymal neoplasm in adults, although a mediastinal location is extremely rare. it has a large volume and varied histologic subtypes. it is characterized by the compression of neighboring structures. computed tomography and magnetic resonance imaging provide useful data for diagnosis. tissue biopsy and histological typing are very important in determining the treatment and are needed for the final diagnosis. radiotherapy and chemotherapy are ineffective treatment modalities. according to the literature, surgical resection is the treatment of choice. long-term follow-up evaluation is indicated since there is a high rate of recurrence.

Abstract: Para avaliar o efeito da clora o organica na uniformidade de distribui o de água e na vaz o de um tubogotejador com vaz o de 2,2 L h-1, foram testados quatro níveis de concentra es de dicloroisocianurato de sódio (N1 = 0, N2 = 15, N3 = 30 e N4 =45 mg L-1 de cloro livre). As avalia es foram realizadas no início do experimento e a cada 100 horas de funcionamento do sistema, totalizando 8 avalia es. No cálculo da uniformidade de aplica o de água foram utilizados os coeficientes de uniformidade deChristiansen (CUC), de distribui o (CUD) e de emiss o (Us). Também se realizou o estudo da vaz o e do coeficiente de varia o da vaz o (CVq). Verificou-se que no nível N1 ocorreram redu es de 23; 30,2 e 8,35%, para o CUC, CUD e Us, respectivamente, sendo que a vaz o apresentou uma redu o de 6,13%, refletindo em um aumento do CVq. Otratamento com dicloro foi eficiente para precaver contra entupimento para todas as concentra es utilizadas e o sistema foi classificado com excelente uniformidade em praticamente todas as avalia es.
