Abstract
The use of dental implants is sometimes accompanied by failure due to periimplantitis disease and subsequently poor esthetics when soft-hard tissue margin recedes. As a consequence, further research is needed for developing new bioactive surfaces able to enhance the osseous growth. Tantalum (Ta) is a promising material for dental implants since, comparing with titanium (Ti), it is bioactive and has an interesting chemistry which promotes the osseointegration. Another promising approach for implantology is the development of implants with oxidized surfaces since bone progenitor cells interact with the oxide layer forming a diffusion zone due to its ability to bind with calcium which promotes a stronger bond. In the present report Ta-based coatings were deposited by reactive DC magnetron sputtering onto Ti CP substrates in an Ar+O2 atmosphere. In order to assess the osteoconductive response of the studied materials, contact angle and in vitro tests of the samples immersed in Simulated Body Fluid (SBF) were performed. Structural results showed that oxide phases where achieved with larger amounts of oxygen (70 at.% O). More compact and smooth coatings were deposited by increasing the oxygen content. The as-deposited Ta coating presented the most hydrophobic character (100°); with increasing oxygen amount contact angles progressively diminished, down to the lowest measured value, 63°. The higher wettability is also accompanied by an increase on the surface energy. Bioactivity tests demonstrated that highest O-content coating, in good agreement with wettability and surface energy values, showed an increased affinity for apatite adhesion, with higher Ca/P ratio formation, when compared to the bare Ti substrates.

Abstract
Ki-67 is a nuclear protein and a proliferation marker frequently used in establishing the prognosis for breast cancer patients. To investigate the prognostic value of the Ki-67 proliferation index in female cats with mammary carcinoma, a prospective study was conducted with 96 animals. The Ki-67 index of primary tumors (n = 96) was initially determined, and whenever possible, the Ki-67 index of regional lymph node metastasis (n = 38) and distant metastasis (n = 16) was also estimated. The optimal cutoff value for the Ki-67 index was determined by univariate and multivariate analysis. Ki-67 indices ≥ 14% were detected in 72.9% (70 of 96) of the tumors. Tumors with a Ki-67 index ≥ 14% were significantly associated with large size (P = .022), poor differentiation (P = .009), presence of necrotic areas (P = .008), estrogen receptor-negative status (P < .0001), fHER2-negative status (P = .003), and shorter overall survival (P = .012). Moreover, Ki-67 expression in the primary tumor was strongly and positively correlated with both regional metastasis (P < .0001; r = 0.83) and distant metastasis (P < .0001; r = 0.83), and was significantly higher in distant metastases when compared with the primary tumor (P = .0009). A similar correlation was also observed between regional and distant metastasis (P < .0001; r = 0.75). On the basis of the above results, the authors propose the adoption of the 14% value as the optimal cutoff for Ki-67 to identify tumors with high risk of disease progression.

Abstract
Astaxanthin, a naturally occurring xanthophyll, is commercially used as a coloring agent in salmon feed, but also marketed as a dietary supplement. The objective of this study was to investigate the subchronic toxicity of synthetic [3S, 3'S]-Astaxanthin in rats. A powder formulation containing approximately 20% [3S, 3'S]-Astaxanthin was administered via the diet to groups of 10 male and 10 female Wistar rats at concentrations of 5000, 15,000 and 50,000 ppm for a period of 13 weeks. A formulation of comparable composition but without [3S, 3'S]-Astaxanthin served as a placebo control. There were no effects observed on survival, clinical examinations, clinical pathology, estrous cycle as well as on sperm parameters. At terminal necropsy, a macroscopically visible brown-blue discoloration of the gastrointestinal contents was noted which was considered to be secondary to the violet-brown color of the test material. No other significant or dose-related abnormalities were found in the tissues collected at termination. Our observations support that ingestion of [3S, 3'S]-Astaxanthin of up to 700-920 mg/kg bw/day in rats in a gelatin/carbohydrate formulation is without adverse effects.

Abstract
The field of transcranial electrical stimulation (tES) has experienced significant growth in the past 15 years. One of the tES techniques leading this increased interest is transcranial direct current stimulation (tDCS). Significant research efforts have been devoted to determining the clinical potential of tDCS in humans. Despite the promising results obtained with tDCS in basic and clinical neuroscience, further progress has been impeded by a lack of clarity on international regulatory pathways. We therefore convened a group of research and clinician experts on tDCS to review the research and clinical use of tDCS. In this report, we review the regulatory status of tDCS, and we summarize the results according to research, off-label and compassionate use of tDCS in the following countries: Australia, Brazil, France, Germany, India, Iran, Italy, Portugal, South Korea, Taiwan and United States. Research use, off label treatment and compassionate use of tDCS are employed in most of the countries reviewed in this study. It is critical that a global or local effort is organized to pursue definite evidence to either approve and regulate or restrict the use of tDCS in clinical practice on the basis of adequate randomized controlled treatment trials.

Abstract
Um experimento foi conduzido com o objetivo de avaliar as características da carcaça e dos componentes não carcaça de cordeiros nascidos de parto simples ou duplo. Dezesseis cordeiros mestiços Texel × Ile de France, machos não castrados, foram desmamados aos 56 dias de idade e abatidos com aproximadamente 28kg de peso corporal. Imediatamente após o abate, cada componente corporal foi pesado separadamente, sendo as carcaças avaliadas após 24 horas de refrigeração a 2°C. Os cordeiros oriundos de parto simples apresentaram superioridade no peso e nos rendimentos da carcaça, além de maior área de olho de lombo. Por outro lado, proporcionalmente ao peso de corpo vazio, o rúmen é maior em cordeiros nascidos de parto duplo, o que resulta incremento da proporção de conteúdo gastrintestinal ao abate. Os resultados deste estudo indicam que, quando abatidos a um mesmo peso, cordeiros oriundos de parto simples possuem carcaças de melhor qualidade, em comparação a cordeiros nascidos de parto gemelar.

Abstract
Avaliou-se o efeito de dietas contendo diferentes teores de borra de soja sobre o consumo de nutrientes, o ganho de peso, as características de carcaça e os componentes do peso vivo de cordeiros terminados em confinamento. Foram utilizados 25 cordeiros, machos, castrados, da raça Texel, distribuídos aleatoriamente em cinco tratamentos compostos por proporções de 0%, 2,89%, 5,77%, 8,65% ou 11,55% de borra de soja na matéria seca das dietas. Houve redução linear do consumo de nutrientes, com exceção do consumo de extrato etéreo, que aumentou linearmente. O peso vivo ao abate, o ganho de peso diário, os pesos e rendimentos de carcaça quente e fria, e os pesos de perna e de costilhar diminuíram linearmente, ao passo que as proporções de rúmen e do trato gastrintestinal, com conteúdo, bem como o conteúdo gastrointestinal, aumentaram linearmente com o aumento dos níveis de borra de soja nas dietas. A proporção de perna foi influenciada de forma quadrática. O aumento da participação de borra de soja na dieta de cordeiros em sistema de confinamento leva à diminuição do desempenho produtivo dos animais. Contudo, o lucro diário obtido por animal não é influenciado, podendo-se inferir que a inclusão de borra de soja até o nível de 11,55% da matéria seca total da dieta é uma alternativa viável para a terminação de cordeiros em confinamento.

Abstract
Control of zoonotic visceral leishmaniosis can be achieved using several available drugs. These drugs present high toxicity and require longer treatment regimens which complicate compliance to the treatment. Other control measures directed to the vector or the reservoirs are useful tools to restrain the spreading of this disease but the effects are transitory. A safe, affordable and efficient vaccine conferring long lasting immunity should be the most cost effective way of controlling zoonotic visceral leishmaniosis. The present study aims at characterizing a cyclophilin protein 1 of Leishmania infantum (LiCyP1) and investigating whether recombinant LiCyP1 (LirCyP1) is able to confer protection against infection by evaluating viable parasite load and the generation of specific CD4(+) and CD8(+) effector and central memory T cells in rodent model. LiCyP1 is present in the cytoplasm of L. infantum amastigotes and promastigotes. Immunization of BALB/c mice with LirCyP1 confers high protection to L. infantum infection, causing a marked reduction in parasite replication in the liver and spleen. Furthermore, helper and cytotoxic memory T cell subsets able to specifically recognize parasite antigens expanded in immunized and in challenged mice. CD4(+) T cell subpopulation of intermediate phenotype (CD62L(high)CD127(low)) of challenging mice also presented an accentuated expansion after the recall. This study demonstrated that LirCyP1 confers partial protection to L. infantum infection, promoting the generation of a desired long lasting immunity. LirCyP1 can be considered a potential candidate for the design of a vaccine against zoonotic visceral leishmaniosis.

Abstract
Determining the genetic basis of inbreeding depression is important for understanding the
role of selection in the evolution of mixed breeding systems. Here, we investigate how
androdioecy (a breeding system characterized by partial selfing and outcrossing) and
dioecy (characterized by obligatory outcrossing) influence the experimental evolution of
inbreeding depression in Caenorhabditis elegans. We derived inbred lines from
ancestral and evolved populations and found that the dioecious lineages underwent more
extinction than androdioecious lineages. For both breeding systems, however, there was
selection during inbreeding because the diversity patterns of 337 single-nucleotide
polymorphisms (SNPs) among surviving inbred lines deviated from neutral expectations. In
parallel, we also followed the evolution of embryo to adult viability, which revealed
similar starting levels of inbreeding depression in both breeding systems, but also
outbreeding depression. Under androdioecy, diversity at a neutral subset of 134 SNPs
correlated well with the viability trajectories, showing that the population genetic
structure imposed by partial selfing affected the opportunity for different forms of
selection. Our findings suggest that the interplay between the disruptions of coevolved
sets of loci by outcrossing, the efficient purging of deleterious recessive alleles with
selfing and overdominant selection with outcrossing can help explain mixed breeding
systems.

Abstract
Objetivou-se avaliar o efeito da porcentagem de glicerina bruta em suplementos sobre as características da carcaça e os componentes do peso vivo de cordeiros lactentes mantidos em pasto de azevém. Foram utilizados 32 cordeiros lactentes, distribuídos nos tratamentos: 0, 10, 20 e 30% de glicerina bruta na matéria seca, em substituição ao milho, no suplemento isoproteico (18% de PB na matéria seca) fornecido diariamente em quantidade equivalente a 2% do peso corporal. As porcentagens de glicerina bruta tiveram efeito linear decrescente sobre peso de carcaça quente, peso de carcaça fria, rendimento de carcaça quente e rendimento de carcaça fria, enquanto as perdas pelo jejum aumentaram. O peso da paleta e o peso do costilhar diminuíram, enquanto a proporção de perna aumentou com o incremento de glicerina bruta no suplemento. Na composição tecidual da paleta, observou-se que a gordura subcutânea, a gordura intermuscular e a gordura total da paleta decresceram linearmente segundo as porcentagens de glicerina bruta. Sobre os componentes do peso vivo, observaram-se diferenças nas proporções de pele, rúmen, omaso, intestino grosso, que aumentaram, enquanto a de gordura renal diminuiu linearmente. Conclui-se que o uso de glicerina bruta em até 30% em suplemento fornecido em comedouro privativo para cordeiros lactentes mantidos em pasto de azevém interfere nas características da carcaça e nos componentes corporais.

Abstract
O presente experimento, conduzido no laboratório de ovinocultura da Universidade Federal de Santa Maria, teve como objetivo avaliar o comportamento ingestivo de cordeiros das raças Texel e Ideal, terminados em confinamento com dietas contendo diferentes teores de casca de soja em substituição da silagem de sorgo. Foram utilizados 40 cordeiros machos não castrados, sendo 20 provenientes da raça Texel e 20 da raça Ideal, desmamados aproximadamente aos 50 dias e confinados em baias individuais, distribuídos aleatoriamente em quatro grupos de acordo com o nível de inclusão de casca de soja na dieta: 0 %, 33,5 %, 66,5 % e 100 % de casca de soja em substituição a silagem de sorgo. O tempo despendido em atividades de alimentação, tempo de mastigação total e o tempo gasto por refeição diminuíram linearmente, enquanto que o período de ócio e a eficiência de alimentação e de ruminação aumentaram linearmente, com o aumento do nível de substituição de silagem de sorgo por casca de soja. Cordeiros da raça Texel permaneceram por mais tempo em atividades de ruminação e de mastigação total, gastaram mais tempo por refei-ção, permaneceram menos tempo em ócio e apresentaram menor eficiência de ruminação quando comparados com cordeiros da raça Ideal, quando confinados em fase de terminação.

Abstract
Glutaric aciduria type 1 is an autosomal recessive disorder caused by deficiency of glutaryl-coenzyme A dehydrogenase, with accumulation of glutaric acid, 3-hydroxyglutaric acid and glutaconic acid. Increased blood glutarylcarnitine levels are the basis for identification of affected infants by newborn screening. Despite the highly variability, this disease usually presents with an acute encephalitis-like encephalopathy in infancy or childhood after a period of normal development. The characteristic neurological sequel is a complex movement disorder due to acute bilateral striatal injury. Frequently, the only abnormality preceding the first episode is a progressive macrocephaly. Although neuroimaging findings are quite variable, the widening of the Sylvian fissures combined with abnormalities of the basal ganglia in a child with macrocephaly should raise the suspicion of this diagnosis. We describe two patients in whom macrocephaly was the only presenting symptom and whose diagnosis was suggested by the brain MRI findings. Our purpose is to illustrate the clinical value of neuroimaging in the diagnosis of glutaric aciduria type 1 even before the onset of neurologic symptoms, which is particularly important if newborn screening is not available.
