1. Oropharyngeal Squamous Cell Carcinoma: Human Papilloma Virus Coinfection with Streptococcus anginosus
Resumo O vírus do papiloma humano (VPH) e bactérias orais capacidade de produção acetaldeído a partir do etanol, tais como Streptococcus anginosus, Prevotella melaninogenica e Fusobacterium naviforme, estão entre os fatores de risco infecciosos do carcinoma de células escamosas de orofaringe (CCEO).

2. Comprobación de la uniformidad de resultados de un equipo de ensayos simultáneos de termofluencia
ABSTRACT The phenomenon of creep occurs in materials that operate under high temperatures and mechanical stresses, causing changes in their structures; such changes are evidenced by a progressive loss of mechanical strength. The characterization of this phenomenon should be performed with appropriate test machines, which are usually dependent on expensive te

3. Polyphasic characterization of bacteria obtained from upland rice cultivated in Cerrado soil
ABSTRACT This work aimed to characterize 20 isolates obtained from upland rice plants, based on phenotypic (morphology, enzymatic activity, inorganic phosphate solubilization, carbon source use, antagonism), genotypic assays (16S rRNA sequencing) and plant growth promotion. Results showed a great morphological, metabolic and genetic variability among bacteri

4. Crop Response to Gypsum Application to Subtropical Soils Under No-Till in Brazil: a Systematic Review
ABSTRACT The use of gypsum to improve the root environment in tropical soils in the southeastern and central-western regions of Brazil is a widespread practice with well-established recommendation criteria. However, only recently gypsum began to be used on subtropical soils in South of Brazil, so available knowledge of its effect on crop yield is incipient a

5. Identification of the capsule type of Pasteurella multocida isolates from cases of fowl cholera by multiplex PCR and comparison with phenotypic methods
The ability of Pasteurella multocida to invade and multiply in its host is enhanced by the presence of the capsule, one of the most important virulence factors for this bacterium. Capsular typing methods are often used in epidemiological and pathogenesis studies of this agent. Five different serogroups have been identified based on serological typing. Howeve

6. Gauchos, gauchesca e políticas da língua no Rio da Prata. Das gacetas populares de Luis Pérez às retóricas da oclusión romántica
Romanticism and gauchesco genre, usually, have been read for a long time in the River Plate as two artistic and aesthetic simultaneous movements. Very little works have centered in the possibilities of the crossings and loans between one and another production, contributing to consolidate this way the distance between cultured poetry and popular poetry, circ

7. Asymmetries in the contributions of On- and Off-mechanisms to the ERG signal
ERG responses were recorded to rapid-on and rapid-off L- and M-cone isolating sawtooth stimuli of different cone contrasts. In addition, the responses were recorded to simultaneous in-phase stimulation of the L- and M-cones at equal cone contrast. Linear responses to mirror imaged rapid-on and rapid-off sawtooth stimuli are also mirror imaged. By adding on-

8. Em busca da região epileptiforme em pacientes com epilepsia do lobo temporal: métodos alternativos baseados em fMRI e EEG-fMRI / Searching for epileptiform region in patients with temporal lobe epilepsy: alternative methods based on fMRI and EEG-fMRI
Temporal lobe epilepsy (TLE) is the most common and resistant form of epilepsy to anti-epileptic drug. There are several types of anti-epileptic drugs used in seizure control. However, in some cases drug treatment is not effective and surgery to remove the epileptogenic zone (EZ) is a recommended alternative. EZ is a theoretical concept and there are many te

9. Tempos de superação para a educação paranaense : uma leitura do discurso oficial a partir dos documentos orientadores das semanas pedagógicas
The present study has as its investigation theme the direction given to educational policy in Paraná from 2003 in order to overcome the educational model based on the neoliberal model. The main objective of the study was to evaluate if the official indications for the development of Pedagogical Weeks in the period 2006 to 2010 had a consistent reference wit

10. In vitro modulation of Bcl-2 levels in small cell lung cancer cells: effects on cell viability
Small cell lung cancer (SCLC) is an aggressive disease, representing 15% of all cases of lung cancer, has high metastatic potential and low prognosis that urgently demands the development of novel therapeutic approaches. One of the proposed approaches has been the down-regulation of BCL2, with poorly clarified and controversial therapeutic value regarding SC

11. EEG spike source localization before and after surgery for temporal lobe epilepsy: a BOLD EEG-fMRI and independent component analysis study
Simultaneous measurements of EEG-functional magnetic resonance imaging (fMRI) combine the high temporal resolution of EEG with the distinctive spatial resolution of fMRI. The purpose of this EEG-fMRI study was to search for hemodynamic responses (blood oxygen level-dependent - BOLD responses) associated with interictal activity in a case of right mesial temp

12. Time course of training-induced microcirculatory changes and of vegf expression in skeletal muscles of spontaneously hypertensive female rats
Exercise-induced vessel changes modulate arterial pressure (AP) in male spontaneously hypertensive rats (SHR). Vascular endothelial growth factor (VEGF) is important for angiogenesis of skeletal muscle. The present study evaluated the time course of VEGF and angiogenesis after short- and long-term exercise training of female SHR and Wistar Kyoto (WKY) rats,
