Abstract: the objective of this work was to monitor the maintenance of citrus tristeza virus (ctv) protective isolates stability in selected clones of 'pêra' sweet orange (citrus sinensis), preimmunized or naturally infected by the virus, after successive clonal propagations. the work was carried out in field conditions in the north of paraná state, brazil. coat protein gene (cpg) analysis of 33 isolates collected from 16 clones of 'pêra' sweet orange was performed using single strand conformational polymorphism (sscp). initially, the isolates were characterized by symptoms of stem pitting observed in clones. then viral genome was extracted and used as template for the amplification of cpg by reverse transcription polimerase chain reaction (rtpcr). rtpcr products electrophoretic profiles were analyzed using the jaccard coefficient and the upgma method. the majority of the clones had weak to moderate stem pitting symptoms and its ctv isolates showed alterations in the sscp profiles. however, the stability of the protective complex has been maintained, except for isolates from two analised clones. low genetic variability was observed within the isolates during the studied years.

Abstract: objective: to investigate the effects of early specialization (defined here as concentrated dedication to a single specialty during undergraduate medical school) on the general skills of newly graduated doctors. sample and methods: applicants for admission to medical residency programs at the university of s?o paulo who had recently finished the undergraduate medical course at the same institution (n=163), grouped by specialty of choice. the study focused on applicants' performance in admissions exams and their undergraduate grade point average. intergroup analysis - applicants for a specific career versus other applicants. intra-group analysis - performance in each respective field of knowledge versus mean performance in the other areas studied. correlation coefficients - between each admissions exam, and between undergraduate gpa and exams. significance level: p<0.05. results and conclusions: there was a tendency towards early specialization in obstetrics-gynecology, psychiatry, and pediatrics, with a loss of performance in areas not directly related to the specialty choice. applicants for the residency program in internal medicine showed overall higher grades on the residency admissions exam and undergraduate gpa, possibly due to a broader and more comprehensive interest in medicine.

Revista da Associa??o Médica Brasileira , 2009, DOI: 10.1590/S0104-42302009000600021
Abstract: objectives: medical education encompasses globally diverse context and conditions. the brazilian scenario seemed a natural environment to study the influence of medical education programs and internship duration on the entrance exam for medical residency. this investigation evaluates some methods used during the entrance exam for medical residency as a means to make a distinction between candidates with longer clerkships. methods: candidates selected for a residency program performed a multiple-choice (mc), an open question (oq) and osce-like tests, an interview and a curriculum analysis for participation in scientific meetings, papers published and voluntary activities. groups were compared for gender, year of graduation, tests and osce scores. results: participants were distributed into two groups based on clerkship duration: 2 years or less than 2 years. there was no difference for the mct score among groups or any of the activities from interview and curriculum analysis. the 2 years clerkship group showed significantly higher oq (p=0.009) and osce-like affective (p=0.025) and knowledge (p=0.002) scores. conclusion: the osce test identified some aspects related to competence acquisition and assessed basic skills and attitudes essential to the supervised practice of medicine during residency. osce discriminated aspects not perceived by the sole use of knowledge tests.

Abstract: Dengue is an important emerging viruses, posing a threat to one-third of the global human population. In 2002, the introduction of DENV-3 in the state of Bahia produced massive epidemic (about 35,000 cases detected) and the first cases of dengue hemorrhagic fever. To understand the nature of the virus circulating at Bahia, E/NS1 sequence was determined for 31 DENV viruses isolated in Bahia during the 2006 and 2007 transmission season, from patients presenting with different degrees of severity. The carboxi-terminal region of the E gene (220 nt) of 31 viruses, isolated from dengue patients with clinical diagnosis of dengue infection were used to determine the genetic variability of dengue 2 (DENV-2) and dengue 3 (DENV-3). Sequence data were used in phylogenetic comparisons with global samples of DENV-2 and DENV-3. DENV-2 sample grouped in the South East Indian genotype, while DENV-3 samples were grouped within Indian genotype. This study is the first report on Bahia isolates during two transmission seasons. Our data confirms reports from other parts of Brazil and different countries showing the DENV-3 (geno-type III) strains circulating in the Americas are closely related, and cluster within the genotype that has been associated with DHF epidemics in different conti-nents.
