Oral bacterial microbiota and traumatic injuries of free-ranging Phrynops geoffroanus (Testudines, Chelidae) in southeastern Brazil
During 2006 and 2007, we collected free-ranging Phrynops geoffroanus, from two anthropogenically altered rivers in southeastern Brazil. Oral microbiological samples were taken for isolation of aerobic and facultative anaerobic bacteria; a physical examination was performed;and we evaluated possible effects on the turtles’ health. Twenty-nine species of bacteria were isolated in Piracicaba River turtles (n=10), and twenty-four species in Piracicamirim stream turtles (n=8), most of them gram-negative. In both sites, potential pathogens for reptiles were: Escherichia coli, Klebsiella pneumoniae, Enterobacter agglomerans, Citrobacter freundii, and Bacillus sp. Although boatpropeller lesions were common on the carapace of the turtles, we have not found turtles with signs of clinical diseases. The oral bacterial microbiota of P. geoffroanus inhabiting the Piracicaba River basin are composed of a diverse microbe spectrum, and long-term studies of the effects of pollution and traumatic injuries on this population and its microbial flora are warranted
PSICOLOGIA, ARTE E POTÊNCIA NO CAPS: oficinas de teatro do oprimido como produtoras de vida
Dentre as estratégias pertencentes aos Centros de Atenção Psicossocial (CAPS) encontram-se as oficinas terapêuticas que visam uma reabilitação social e produção de vida nos corpos (AVILA; FONSECA. 2007). As oficinas terapêuticas expressivas são entendidas catalisadores das experiências psicológicas, apontando para o caráter de importante potencializador dos processos de subjetivação
Microbiota bacteriana oral e lesões traumáticas no cágado Phrynops geoffroanus (Testudines, Chelidae) no sudeste do Brasil
Entre 2006 e 2007, coletamos amostras microbiológicas da cavidade oral de cágados Phrynops geoffroanus de vida livre, em dois rios antropizados da região sudeste do Brasil, para o isolamento de bactérias aeróbicas e anaeróbicas facultativas, e realizamos um exame físico e avaliamos possíveis efeitos sobre o estado de saúde dos animais. Vinte e nove espécies de bactérias foram isoladas em cágados do rio Piracicaba (n=10), e vinte e quatro espécies em animais do ribeirão Piracicamirim (n=8), a maioria delas gram-negativas. Em ambos os sítios estudados foram isolados patógenos potenciais para répteis, como Escherichia coli, Klebsiella pneumoniae, Enterobacter agglomerans, Citrobacter freundii e Bacillus sp. Embora lesões na carapaça dos cágados, causadas por hélices de barcos, foram um achado comum no exame físico, não encontramos animais com sinais clínicos de doenças. A microbiota bacteriana oral dos cágados que habitam a bacia do rio Piracicaba é composta por um amplo espectro de bactérias, e estudos de longa duração sobre os efeitos da poluição e de lesões traumáticas nesta população e de sua microbiota oral são recomendados.During 2006 and 2007, we collected free-ranging Phrynops geoffroanus, from two anthropogenically altered rivers in southeastern Brazil.

Notes on the hematology of free-living Phrynops geoffroanus (Testudines: Chelidae) in polluted rivers of Southeastern Brazil
Phrynops geoffroanus (Schweigger, 1812) is the freshwater turtle with the widest geographical distribution in South America. During 2006, physical examination and hematological evaluation were performed on free-ranging turtles from two polluted rivers, the Piracicaba River (n = 51) and its tributary Piracicamirim (n = 42), in southeastern Brazil. Red blood cell and thrombocyte counts, mean corpuscular volume and mean corpuscular hemoglobin levels differed in turtles from the two water courses. Although free-ranging turtles showed ectoparasites and boat propeler lesions, animals apparently had no signs of clinical disease. In spite of our results, further monitoring of the demography and health status of Phrynops geoffroanus in anthropogenically altered environments is recommended.FAPESP [05/00210-9]CNPqCoordenacao de Aperfeicoamento de Pessoal de Nivel Superior (CAPES
Wireless Connectivity of a Ground-and-Air Sensor Network
This paper shows that, when considering outdoor scenarios and wireless
communications using the IEEE 802.11 protocol with dipole antennas, the ground
reflection is a significant propagation mechanism. This way, the Two-Ray model
for this environment allows predicting, with some accuracy, the received signal
power. This study is relevant for the application in the communication between
overflying Unmanned Aerial Vehicles (UAVs) and ground sensors. In the proposed
Wireless Sensor Network (WSN) scenario, the UAVs must receive information from
the environment, which is collected by sensors positioned on the ground, and
need to maintain connectivity between them and the base station, in order to
maintain the quality of service, while moving through the environment.Comment: 8 pages, 11 figure
Spin-Polarized STM for a Kondo adatom
We investigate the bias dependence of the tunneling conductance between a
spin-polarized (SP) scanning tunneling microscope (STM) tip and the surface
conduction states of a normal metal with a Kondo adatom. Quantum interference
between tip-host metal and tip-adatom-host metal conduction paths is studied in
the full range of the Fano parameter . The spin-polarized STM gives rise to
a splitting of the Kondo peak and asymmetry in the zero-bias anomaly depending
on the lateral tip-adatom distance. For increasing lateral distances, the Kondo
peak-splitting shows a strong suppression and the spin-polarized conductance
exhibits the standard Fano-Kondo profile.Comment: new version with improved discussion. added one figure. 12 pages

NDUFV1 mutations in complex I deficiency: Case reports and review of symptoms.
Mitochondrial complex I (CI) deficiency is the most common oxidative phosphorylation disorder described. It shows a wide range of phenotypes with poor correlation within genotypes. Herein we expand the clinics and genetics of CI deficiency in the brazilian population by reporting three patients with pathogenic (c.640G>A, c.1268C>T, c.1207dupG) and likely pathogenic (c.766C>T) variants in the NDUFV1 gene. We show the mutation c.766C>T associated with a childhood onset phenotype of hypotonia, muscle weakness, psychomotor regression, lethargy, dysphagia, and strabismus. Additionally, this mutation was found to be associated with headaches and exercise intolerance in adulthood. We also review reported pathogenic variants in NDUFV1 highlighting the wide phenotypic heterogeneity in CI deficiency
