MUTAGENS ,RICE genetics ,RICE varieties - Abstract
The increase of yield potential in new rice (Oryza sativa L.) varieties has been a major challenge for genetic improvement. The generation of mutants, followed by their characterization, constitutes a great possibility to isolate and select genes and genotypes that present agronomic traits of interest. This study aimed to evaluate the effect of chemical mutagen ethyl methane sulphonate (EMS) on agronomic traits in 340 M3 families of rice derived from BRS Querência cultivar. Seeds from each family and the original genotype BRS Querência were sown in the experimental field, and the characters main panicle length, main panicle weight, main panicle grain weight, flag leaf width and plant height were evaluated. Data were subjected to analysis of variance (p = 0.05), and a comparison of means was carried out by Dunnett's test at 5% significance. The results show that there is genetic variability among the mutant families, suggesting that the mutagen EMS at 1.5% is effective for generating mutants for all assessed traits. Among the characters, plant height was the most affected by the mutagen, which provided an increase in the character. For the main panicle length character, seven families showed means above the control; for main panicle weight and grain weight, four and six mutant families were observed, respectively, with a superior performance in comparison to the control.

ULTRABASIC rocks , *SERPENTINE , *CHLORITE minerals , *OLIVINE , *PYROXENE , *ROCK-forming minerals - Abstract
In Amarantina district of Ouro Preto (State of Minas Gerais, Brazil), ultramafic rock exposures are found along two areas of about 500 m² each. The rocks crop out in the Bação complex, which is the gneissic basement of the Rio das Velhas greenstone belt in the central portion of the Quadrilátero Ferrífero (QF). The interest in a petrogenetic study of the ultramafic rocks is the partial preservation of igneous minerals, which are not observed in most of the completely metamorphosed ultramafic rocks in the QF. Among them, the steatites and the serpentinites are the best studied because of their economic importance. The ultramafic rocks from Amaranima are classified as metaperidotites due to the equigranular texture characteristic of plutonic origin. The rocks are made up of large grains of olivine, pyroxene, and spinel preserved from de original magmatic rock, which are distributed in a fine grained mass with talc, serpentine, chlorite, amphibole, and opaque minerals. Scarce arite (NiSbAs) and breithauptite (NiSb) were generated after pentlandite during hydrothermal metamorphism. Comparison of the chemical composition with a metakomatiite with spinifex texture from de QF as well as with known komatiitic rocks from other parts of the world reveals that the metaperidotites are chemically similar to non Al-depleted komatiites. Therefore it is probable that the studied ultramafic rocks correspond to the plutonic portion of the komatiitic magmatism of the Nova Lima group, at the base of the Rio das Velhas greenstone belt.

- Abstract
Miniemulsion polymerization is a promising approach to produce and tailor pressure sensitive adhesives (PSAs). In this paper, a systematic comparison of the adhesive properties of latexes produced by miniemulsion and conventional emulsion polymerization is presented. Specifically, the influence of the total surfactant concentration, chain transfer agent concentration and chemical composition on the final adhesive properties of the polymer 2‐ethyl hexyl acrylate/methyl methacrylate/acrylic acid was discerned using a 23factorial design for each polymerization method. In addition to the adhesive properties (i.e., loop tack, peel strength and shear strength), molecular weight distribution, particle size distribution (PSD) and glass transition temperature were analyzed. The results show that under the conditions used in this work, it is possible to produce PSAs using miniemulsion polymerization, a process wherein monomer droplet nucleation is the dominant particle nucleation mechanism. The use of a miniemulsion polymerization process, as opposed to the conventional emulsion technique, produced several differences such as larger particles sizes and narrower molecular weight distributions. Focusing on the PSA films that exhibited adhesive rather than cohesive failure, the PSA films generated via miniemulsion polymerization displayed higher values of loop tack and peel strength compared to those produced via conventional emulsion polymerization. Shear strength results were strongly dependent on the amount of gel content and sol molecular weight for both cases.

FAMILY support , *YOUNG adults , *OPTIMISM , *ADULT children , *FINANCIAL stress - Abstract
The present study focuses on the role of family support to young adult children during COVID‐19 in ameliorating the negative financial impact of the pandemic. Guided by the Conservation of Resources (COR) Theory of stress and coping, we conceptualize the negative financial impact due to COVID‐19 as a source of financial stress that would be associated with lower levels of both financial wellbeing and positive outlook of young adults. We rely on data collected from a multinational sample of young adults (ages 18–30) from six countries (China, Italy, Lithuania, Portugal, Slovenia, US; N = 2102) over a 3‐month period (July 2020–September 2020). We tested the potential effects of two types of support (i.e., parental financial support and family emotional support) using path analysis. While we find a consistent positive association between family emotional support and both financial wellbeing and positive outlook, we also find a consistent negative association between parental financial support and financial wellbeing, and a nonsignificant or negative association (Lithuania only) with a positive outlook. The significant interaction between COVID‐19 financial impact and family emotional support on young adults' positive outlook reveals that the benefit of family emotional support is more evident when the negative financial impact is low or moderate. We discuss the implications of these findings in assisting young adults to cope with financial disruptions. [ABSTRACT FROM AUTHOR]

A comunicação parento-filial representa uma dimensão essencial do exercício da parentalidade. Apesar de muitas famílias procurarem intervenção psicoterapêutica por considerarem que o seu problema reside na falta de comunicação, o Modelo da Pragmática da Comunicação Humana postula que é impossível não comunicar e, por esse motivo, comunicação e comportamento são sinónimos aquando da significação que se faz das relações familiares. Como uma dança (tendo os autores deste ensaio privilegiado o Bailinho da Madeira enquanto metáfora), a comunicação parento-filial rege-se por pressupostos e regras que permitem compreender e analisar a identidade de cada família e o modo como se operacionaliza a parentalidade. Tal como outras funções e tarefas, também o exercício da parentalidade se altera à medida que o ciclo vital da família evolui e, nesse sentido, os padrões de comunicação estabelecidos também se modelam, apresentando especificidades distintas em famílias com filhos em idade escolar e famílias com adolescentes. Pretende-se com este ensaio teórico reavivar os contributos do Modelo da Pragmática da Comunicação Humana para as relações familiares, bem como, apresentar uma sucinta caracterização dos padrões comunicacionais entre pais e filhos de famílias portuguesas. Parent-child communication is a key dimension of parenthood. Although many families seek psychotherapeutic interventions claiming that their problem is related to the absence of communication, the Pragmatics of Human Communication Model posits that it is impossible to not communicate and, for that reason, communication and behaviour are synonymous when we consider the signification of family relationships. Like a dance (having the authors of this essay focused their attention on the Bailinho da Madeira as a metaphor), parent-child communication is regulated by assumptions and rules that enable to understand and analyse the identity of each family and the way in which parenthood is operationalized. As with other roles and tasks, the parental exercise also changes throughout the family life cycle, with the communication patterns being shaped, and presenting differentiated specificities in families with school-aged children and families with adolescents. This theoretical essay intends to recall the contributions of the Pragmatics of Human Communication Model to family relationships, as well as to present a brief characterization of the communication patterns between parents and children from Portuguese families.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) O feijão tem grande importância nutricional, econômica e social, mas sua produção pode ser afetada por fatores climáticos adversos, como a ocorrência de baixas temperaturas. O estresse por resfriamento pode prejudicar a germinação e emergência da cultura, se ocorrer no início do ciclo, ou nos componentes do rendimento quando ocorrer na fase reprodutiva causando perdas de produtividade em ambos os casos. O objetivo do trabalho foi verificar a resposta de cultivares de feijão ao estresse por frio na fase de florescimento. Para isso, sete cultivares de feijão foram semeadas em vasos e cresceram em casa de vegetação com temperaturas entre 15 e 35°C até estádio R6, quando metade dos vasos foi transferida para câmara climática para crescimento de plantas sob temperatura de 5a 9°C durante três dias, e foto período de 12 horas. Após esse período, o material vegetal foi coletado para análise das concentrações de açúcares solúveis totais, prolina e atividade enzimática. As plantas foram mantidas em casa de vegetação até a maturidade fisiológica, quando foram analisados seus componentes do rendimento. Foi realizado teste de agrupamento de médias para os caracteres fisiológicos e agronômicos e análise de componentes principais. De maneira geral, o estresse por frio causou redução nos componentes de rendimento das cultivares,aumento da síntese de prolina e atividade enzimática da catalase. O componente do rendimento mais afetado pelo frio foi o número de legumes por planta. Uma menoratividade da enzima superóxido dismutase no frio proporciona maior tolerância das cultivares a esse estresse. BRSMG Madrepérola e IAC Imperador foram as cultivares mais sensíveis ao estresse por frio, apresentando a maior redução nos componentes do rendimento, enquanto que ANFc 9 e ANfp 110 foram as mais tolerantes, mostrando que possuem mecanismos adaptativos a baixas temperaturas. Common bean has great nutritional, economic and social importance, but itsproduction can be affected by adverse climatic factors, such as the occurrence of lowtemperatures. Cold stress can impair the germination and emergence of the crop, if itoccurs at the beginning of the cycle of the plants. When cold stress occur at the endof the cycle of the plants, the yield components can be directly affected. In bothcases, losses in productivity can be observed. This work aimed to verify the responseof common bean cultivars to cold stress during the flowering phase. For this, sevencommon bean cultivars were sown in pots and grown in a greenhouse with atemperature between 15 and 35°C until the R6 stage, when half of the pots weretransferred to a climatic chamber for plant growth under a temperature of 5 to 9°Cfor three days, and a 12 hours photoperiod. After this period, the plant material wascollected for analysis of concentrations of total soluble sugars and proline andenzymatic activity. The plants were kept in a greenhouse until physiological maturity,when their yield components were caused. It was the test of grouping means for thephysiological and agronomic traits and principal component analysis were performed.In general, cold stress caused a drop in yield components of cultivars, increasedproline synthesis and enzyme activity of catalase. The yield component most affectedby cold was the number of pods per plant. A lower activity of the enzyme superoxidedismutase in the cold offers tolerance of the cultivars to this stress. BRSMGMadrepérola and IAC Imperador were the cultivars most sensitive to cold stress, thegreatest reduction in yield components, while ANFc 9 and ANfp 110 were moretolerant, showing that they have adaptive mechanisms at low temperatures.

Terapia familiar ,Aliança terapêutica - Abstract
Dissertação de mestrado em Psicologia Clínica e Saúde (Psicoterapia Sistémica e Familiar), apresentada à Faculdade de Psicologia e de Ciências da Educação da Universidade de Coimbra. O objetivo principal deste estudo é perceber qual a associação da avaliação da aliança terapêutica feita a partir do ponto de vista de observadoras/es e a partir do ponto de vista da/o própria/o terapeuta. Para avaliar a força da aliança terapêutica é usado o Sistema de Observação da Aliança em Terapia Familiar (SOFTA - Friedlander, Escudero, & Heatherington, 2006). Nomeadamente, é utilizado o SOFTA-o para a recolha observacional e o SOFTA-s para a recolha de autorresposta, tendo por base a análise da 1ª sessão. Os resultados demonstram uma associação baixa entre os dois métodos de avaliação. As ações das/os terapeutas não parecem ser congruentes com a sua perceção. A análise da frequência dos descritores comportamentais permite concluir que os terapeutas contribuem mais para a dimensão Envolvimento e Conexão Emocional do que para as dimensões Segurança e Partilha de Objetivos. São as dimensões específicas da terapia familiar e de casal para as quais as/os terapeutas menos contribuem. Este resultado pode ser útil para a formação de terapeutas e para uma melhor prática clínica, indicando as dimensões às quais as/os terapeutas deveriam ter mais em atenção. The principal goal of this study is to understand which is the association between a therapeutic alliance’s evaluation from the observer’s point of view and the therapist’s own. The System for Observing Family Therapy Alliances (SOFTA - Friedlander, Escudero, & Heatherington, 2006) is used to evaluate the strength of the therapeutic alliance. The SOFTA-o is used for the observational sample and the SOFTA-s is used for the self-report sample, the 1st session being the basis for analysis. The results show that there is a low association between these two assessment methods. The therapist’s actions don’t seem to be congruent with his or her perceptions. The frequencies’ analysis of comportamental descriptors shows that therapists contribute more to the dimensions Engagement and Emotional Connection than for Safety and Shared Purpose. The specific dimensions of family and couple therapy are those to which the therapists least contribute. These results may be useful for therapists’ training and a better clinical practice, indicating the dimensions to which therapists should give more attention.

Satisfação conjugal ,Ciclo vital do casal - Abstract
Dissertação de mestrado em Psicologia Clínica e da Saúde (Psicoterapia Sistémica e Familiar), apresentada à Faculdade de Psicologia e de Ciências da Educação da Universidade de Coimbra. A complexidade e paradoxalidade inerente à díade conjugal dificultam a sua investigação ao longo do ciclo vital do casal. A fim de contribuir para o conhecimento em torno desta temática, o presente estudo recorreu a uma amostra de 234 indivíduos casados portugueses com o objetivo geral de estudar a satisfação conjugal, o amor romântico, o coping diádico e a sensibilidade olfativa ao longo do ciclo vital do casal (fase da fusão, autonomia e empatia), de acordo com a teoria de Franck-Lynch (1986, citado por Lourenço, 2006; citado por Relvas, 1996). Os resultados do estudo revelaram que os indivíduos casados que se encontram na fase da fusão, têm uma maior perceção de coping diádico, quando comparados com sujeitos casados que se encontram na fase da empatia. Relativamente à correlação das variáveis verificou-se que o coping diádico parece estar correlacionado com o amor romântico e com a satisfação conjugal. Por fim, também se verificou que a satisfação conjugal se encontra correlacionada com o amor romântico e com a sensibilidade olfativa. Foram discutidas implicações da investigação na intervenção. The complexity and the paradoxes inherent to the conjugal dyad difficult its investigation throughout the life cycle of the couple. In order to contribute to the knowledge about this issue, the present study used a sample of 234 married Portuguese individuals with the general objective of studying marital satisfaction, romantic love, dyadic coping and olfactory sensitivity throughout the life cycle of the couple (fusion stage, autonomy, empathy), according to Franck-Lynch’s theory (1986, cited by Lourenço, 2006, cited by Relvas, 1996). The results of the study revealed that married individuals, who are at the fusion stage, have a larger perception of dyadic coping when compared to married individuals who are at the empathy stage. In regards to the correlation of the variables, it was observed that the dyadic coping seems to be correlated to romantic love and to marital satisfaction. Finally, it was also verified that marital satisfaction is correlated with romantic love and with olfactory sensitivity. Implications of the investigation were also discussed in the intervention.

Terapia familiar ,Aliança terapêutica - Abstract
Dissertação de mestrado em Psicologia Clínica e Saúde (Psicoterapia Sistémica e Familiar), apresentada à Faculdade de Psicologia e de Ciências da Educação da Universidade de Coimbra A aliança terapêutica é considerada uma importante variável do processo terapêutico, dado que é um bom preditor dos resultados da terapia, independentemente das modalidades psicoterapêuticas utilizadas (Horvath & Bedi, 2002). A perceção dos clientes é aquela que mais se relaciona com os resultados obtidos (Horvath & Bedi, 2002). A presente investigação tem assim como principal objetivo compreender de que forma a perspetiva dos clientes acerca da aliança se correlaciona com os comportamentos observados. Para realização da investigação recorreu-se ao System for Observing Family Therapy Alliances (SOFTA, Friedlander, Escudero, & Heatherington, 2006), versão autorresposta e versão observacional, tendo por base a análise da 1ª sessão de terapia. A amostra é constituída por 35 sujeitos pertencentes a 14 casos arquivados de terapia familiar e de casal. Os resultados obtidos indicam que das quatro dimensões da aliança terapêutica, apenas a Conexão Emocional e o Sentimento de Partilha de Objetivos na família apresentam correlações significativas nas duas versões do SOFTA. Estes resultados são um contributo para a área da aliança nas terapias conjuntas, uma vez que permitiram conhecer a associação entre a perspetiva interna dos clientes e os comportamentos observados. The therapeutic alliance is an important variable of the therapeutic process, as it is a good predictor of therapy's results, independently of psychotherapeutic modalities used (Horvath & Bedi, 2002). The client’s perception is the one that most closely relates to the results obtained, so this research aims to understand how their perspective of their alliance with the observed behavior. The research was carried out using the System for Observing Family Therapy Alliances (SOFTA- Friedlander, Escudero & Heatherington, 2006), self-report version and observational version, based on the analysis of the first therapy session. The sample consisted of 35 subjects, belonging to 14 cold cases of family and couples therapy. The results indicate that, considering the four dimensions of the therapeutic alliance, only Emotional Connection and Shared Sense of Purpose within the client's family showed significant correlations. These results are a contribution to the area of conjoint therapies once enabled to know the association between the internal perspective of the clients and their behavior observed.

Angola ,Malária ,Adesão ao tratamento - Abstract
Dissertação de mestrado em Psicologia Clínica e da Saúde (Sistémica, Saúde e Familia), apresentada à Faculdade de Psicologia e de Ciências da Educação da Universidade de Coimbra A malária é uma das doenças crónicas mais incidentes no mundo, sendo reconhecida como um problema de saúde pública. A adesão ao tratamento é um conjunto de ações que incluem a toma de medicamentos, ter seguimento em consultas e adotar uma vida saudável. Este estudo pretende então analisar o impacto das variáveis familiares na adesão aos tratamentos na malária. Para o efeito, utilizou-se um questionário sociodemográfico e a Medida de Adesão aos Tratamentos (MAT). O instrumento revelou uma boa conssistência interna, sendo o coeficiente do alfa de Cronbach de.79. Esta investigação foi desenvolvida numa amostra constituída por 50 indivíduos com malária. Os resultados deste estudo revelaram que não parece haver um impacto significativo das variáveis familiares nos resultados da MAT. Em conclusão, e apesar do cariz exploratório desta investigação, julga-se pertinente desenvolver estudos futuros acerca do impacto de outras variváveis familiares na adesão aos tratamentos, dado que estes se constituem um aspeto importante da intervenção e compreensão desta problemática. Malaria is a chronic disease more incidents in the world and is recognized as a public health problem. Adherence to treatment is a set of actions that include taking medications, have follow-up consultations and adopt a healthier lifestyle. This study will then examine the impact of family variables on treatment adherence in malaria. For this goal, we used a sociodemographic questionnaire and the Accession measure to treatment (MAT). The instrument showed good internal consistency, and the Cronbach alpha coefficient de.79. This research was developed in a sample of 50 individuals with malaria. The results of this study revealed that there seems to be a significant impact of family variables in the results of the MAT. In conclusion, despite the exploratory nature of this investigation, it is thought appropriate to develop future studies on the impact of other family variables on treatment adherence, as these constitute an important aspect of the intervention and understanding of this issue.

Conjugalidade ,Satisfação conjugal - Abstract
Dissertação de mestrado em Psicologia Clínica (Psicoterapia Sistémica e Familiar), apresentada à Faculdade de Psicologia e de Ciências da Educação da Universidade de Coimbra. O presente estudo pretende contribuir para uma melhor compreensão da conjugalidade, mais especificamente da satisfação conjugal, do amor romântico, do coping diádico e da sensibilidade olfativa associadas à influência de variáveis sociodemográficas. Para tal foi administrado um protocolo constituído por cinco instrumentos, a 283 sujeitos heterossexuais casados, com o intuito de recolher informações referentes ao sexo, idade, nível de escolaridade, situação financeira, religiosidade e às dimensões relativas à conjugalidade. Os resultados mostram que a maioria dos aspetos da conjugalidade em estudo, não parece ser influenciada pelas características sociodemográficas dos sujeitos. No entanto, a perceção da sensibilidade olfativa parece diferir entre o sexo feminino e masculino, sendo que as mulheres apresentam uma maior sensibilidade e atribuem uma maior importância aos odores. A par disto, os resultados sugerem que ocorre uma diminuição na perceção do coping diádico à medida que a idade aumenta. Este estudo alerta para a importância de continuar a investigar nesta área, além de poder impulsionar novas linhas de estudo, fornecendo ainda informação relevante para a intervenção clínica com casais e/ ou indivíduos. The present study intends to increase the comprehension of conjugal relationships, mainly the conjugal satisfaction, the romantic love, the dyadic coping and the olfactory sensibility associated with the influence of multiple socio demographic variables. To accomplish this, a protocol comprised of five instruments was applied to 283 married heterosexual individuals. Its aim was to gather information concerning sex, age, school education/ schooling, financial status, religiousness and the dimension regarding conjugality. The results showed that the majority of the studied aspects related to conjugality did not seem to be influenced by the socio demographic characteristics of the studied individuals. However, the perception of the olfactory sensibility seems to differ between males and females, since women show higher sensibility and give more importance to odours. Besides, the results suggest that as the age increases, there is a lowering effect in the perception of the dyadic coping. Not only does this study alert to the importance of performing further research in this field, but it can also develop new areas of study and give relevant information regarding clinical intervention given to couples and/or individuals.

- Abstract
Background: In the COVID-19 pandemic, the increase in the incidence of cardiovascular diseases (CVD) and mortality from them has been recognized worldwide. In Brazil, the impact of COVID-19 on CVD must be evaluated., Objectives: To assess the impact of the current pandemic on the numbers of hospital admissions (HA), in-hospital deaths (ID), and in-hospital fatality (IF) from CVD by use of national epidemiological data from the Brazilian Unified Public Health System., Methods: Time-series observational study using comparative analysis of the HA, ID, and IF due to CVD recorded from January to May 2020, having as reference the values registered in the same period from 2016 to 2019 and the values projected by linear regression methods for 2020. The statistical significance level applied was 0.05., Results: Compared to the same period in 2019, there was a 15% decrease in the HA rate and a 9% decrease in the total ID due to CVD between March and May 2020, followed by a 9% increase in the IF rate due to CVD, especially among patients aged 20-59 years. The HA and IF rates registered in 2020 differed significantly from the projected trend for 2020 (p = 0.0005 and 0.0318, respectively)., Conclusions: During the first months of the pandemic, there were a decline in HA and an increase in IF due to CVD in Brazil. These data might have resulted from the inadequate planning of the CVD management during the pandemic. Thus, immediate actions are required to change this scenario.

- Abstract
Background: Carious lesions and dental fractures cause weakening in the dental structure. In these situations, endodontic treatment and prosthetic rehabilitation using an intraradicular post are indicated. However, the postspace preparation of the root canal further weakens the dental remnant, especially if there is no ferrule present. This study aimed to evaluate the stress distribution in endodontically treated upper premolars treated with different rehabilitation approaches., Materials and Methods: An endodontically treated first upper premolar was modeled for finite element analysis. Three different approaches were carried out on this model: rehabilitation with fiberglass post (FCP), endocrown (ECW), or buildup. The models were exported in STEP format to the analysis software (ANSYS 17.2, ANSYS Inc., Houston, TX, USA). The solids were considered isotropic, homogeneous, and linearly elastic. A mechanical, structural static analysis was used as the criterion of maximum principal stress to show regions under tensile stress to evaluate the stress distribution in the restoration, cementation line, and root. A load of 400 N (90°) was applied to the lingual triangular ridge. The values of maximum principal stress in MPa were evaluated through colorimetric graphs., Results: Similar stress concentration was observed for all groups. However, the ECW group presented higher values in the restoration/cement interface and root dentin., Conclusions: All the treatment modalities had favorable mechanical behavior to support the masticatory loads; nevertheless, the ECW group presented a higher risk of detachment failure., Competing Interests: There are no conflicts of interest.

- Abstract
Aim: Endocrown restorations are an alternative to restore end-odontically treated teeth. Due to the fact that in the literature it is recommended a remnant of 1.5 mm, different heights of endocrown were elaborated and analyzed, obtaining possible faults and their location. This study aimed to evaluate the mechanism of stress distribution in the tooth/restoration set, varying two factors: "restoration height"-three levels, and load application-two levels (oblique or axial), totaling six groups., Materials and Methods: For finite element analysis (FEA), a maxillary premolar was modeled with an endodontic treatment. Then, this template was triplicated and each copy received an endocrown restoration of different heights: G6 (4.5 mm), G7 (5.5 mm), and G8 (6.5 mm). The models were exported in STEP format to analysis software (ANSYS 17.2, ANSYS Inc.). During preprocessing, the solids were considered isotropic, linearly elastic, and homogeneous. Initially, a load (300 N) was axially applied in the central fossa region. For a second evaluation, an oblique load (300 N) was applied on the grinding slope of functional cusp. System fixation occurred at the base of poly-urethane cylinder. Results were evaluated through maximum principal stress (MPS)., Results: For axial load, lower stress values were generated in all groups. For oblique load, G8 showed a higher stress concentration in the cement layer and root dentin., Conclusion: When an endocrown restoration is performed, there is a tendency of failure in the cement line and in the root directly proportional to its size. However, regardless of the size of the element to be reconstituted, the axial direction of the masticatory loads tends to decrease stress concentration., Clinical Significance: When performing an endocrown restoration, care must be taken with its high regardless the tooth remnant high, altering even the anatomical angulations of the occlusal face, when necessary, to avoid stress concentration in thick areas.

- Abstract
Introduction: The current study examined the psychometric properties of the Portuguese version of the Family Distress Index (FDI). The FDI is an 8-item self-report measure that assesses family maladaptation, providing an index of family outcomes within the resiliency model of family stress, adjustment, and adaptation., Method: Participants were 459 adults, who completed measures of family distress (FDI) and family functioning (Systemic Clinical Outcome Routine Evaluation; SCORE-15)., Results: Exploratory and confirmatory factor analyses supported a unidimensional factorial structure. Results also indicated that the FDI has good internal consistency and temporal stability. The positive and significant correlation between FDI and SCORE-15' scores demonstrated its convergent validity. Through receiver operating characteristic (ROC) analysis, we determined a cut-off score of 12 for identifying probable family distress., Discussion: In sum, the Portuguese version of the FDI is a valid and reliable instrument, which can foster the development of future empirical studies focused on family adaptation in diverse contexts of adversity, namely in health care settings.

- Abstract
In order to regenerate the dental pulp, many strategies have been developed as phototherapy. In the pulp repair, we do not know if gallium-aluminum-arsenide (GaAlAs) laser preserves the primary odontoblasts or stimulates the formation of more dentin matrix when dental pulp is damaged. The aim of the present study was to examine the effect of laser phototherapy (λ780 nm) on vascularization, inflammation, density of the primary odontoblast layer, and formation of reactionary and reparative dentin in the dental pulp by provoking extrusion of the rat incisor. The upper incisors were extruded 3 mm and then repositioned into their original sockets followed by a laser irradiation of the palatal mucosa (λ = 780 nm; p = 70 mW; CW; 4.2 J/cm
2 ; 60 s) every 48 h. Non-traumatized and/or non-irradiated incisors were used as the controls. At 8 and 30 days after surgery, incisors were processed for histological and histomorphometric analysis. Morphological analysis revealed no differences in vascularization between groups, but showed discrete inflammation in some non-irradiated and injured specimens, which correlated with a more irregular reparative dentin. The density of primary odontoblasts in the groups treated with lasers was higher when compared to non-irradiated groups, but no statistically significant difference between groups (p > 0.05). The thickness of the tertiary dentin was increased in both traumatized groups with no statistically significant difference between non-irradiated and irradiated groups (p > 0.05).The present findings revealed that the GaAlAs laser induced small changes on dentin-pulp complex, with more regular dentin matrix in the irradiated dental pulps.- Published

- Abstract
Background:: The nail involvement in psoriasis is related to psoriatic arthritis and may represent a predictor of the disease., Objectives:: To analyze, through nail clipping, clinically normal and dystrophic nails of patients with cutaneous psoriasis and psoriatic arthritis., Methods:: This is a cross-sectional multicenter study, conducted between August 2011 and March 2012. Patients were divided into four groups: patients with cutaneous psoriasis and onychodystrophy, patients with cutaneous psoriasis and clinically normal nails, patients with psoriatic arthritis and onychodystrophy and patients with psoriatic arthritis and clinically normal nails. We calculated NAPSI (Nail Psoriasis Severity Index) of the nail with more clinically noticeable change. After collection and preparation of the nail clipping, the following microscopic parameters were evaluated: thickness of the nail plate and subungual region, presence or absence of parakeratosis, serous lakes, blood, and fungi., Results:: There were more layers of parakeratosis (p=0.001) and a greater thickness of the subungual region in patients with cutaneous psoriasis and onychodystrophy (p=0.002). Serous lakes were also more present in the same group (p=0.008) and in patients with psoriatic arthritis and normal nails (p=0.047). The other microscopic parameters showed no significant difference between normal and dystrophic nails or between patients with psoriatic arthritis or cutaneous psoriasis., Study Limitations:: Small sample size and use of medications., Conclusions:: Nail clipping is a simple and quick method to assess the nails of patients with nail psoriasis although does not demonstrate difference between those with joint changes or exclusively cutaneous psoriasis.

- Abstract
Understanding of gene expression and metabolic, biological and physiological pathways in ovarian follicular development can have a significant impact on the dynamics of follicular atresia or survival. In fact, some oocyte loss occurs during the transition from secondary to early tertiary follicles. This study aimed to understand, by microarray analysis, the temporal changes in transcriptional profiles of secondary and early antral (tertiary) follicles in caprine ovaries. Ovarian follicles were microdissected and pooled to extract total RNA. The RNA was cross hybridized with the bovine array. Among 23,987 bovine genes, a total of 14,323 genes were hybridized with goat mRNAs while 9,664 genes were not. Of all the hybridized genes, 2,466 were stage-specific, up- and down-regulated in the transition from secondary to early tertiary follicles. Gene expression profiles showed that three major metabolic pathways (lipid metabolism, cell death, and hematological system) were significantly differentiated between the two follicle stages. In conclusion, this study has identified important genes and pathways which may potentially be involved in the transition from secondary to early tertiary follicles in goats.

- Abstract
Background: There is no appropriate and reliable method of evaluating and monitoring severity in rosacea., Objective: To determine the importance of nailfold capillaroscopy as a diagnostic and prognostic method for patients with rosacea., Methods: A cross-sectional study where eight patients with rosacea and 8 control subjects were submitted to nailfold capillaroscopy from May to July 2009. We collected clinical data related to gender, age, skin phototype, and rosacea stage according to Plewig and Kligman classification and the classification of the National Rosacea Society. Additionally, we evaluated the progression of the disease and treatment therapies previously used., Results: The majority of the patients evaluated (6 out of 8 patients) had rosacea subtype I (vascular) or erythematotelangiectatic rosacea. The mean duration of the disorder was 5.96 years, and 87.5% of the patients were under treatment with topical metronidazole. Nailfold cappilaroscopy showed that evidence of devascularization was absent in both groups., Conclusion: Nailfold capillaroscopy presents a nonspecific pattern and does not seem to help in the diagnosis or prognosis of rosacea.

- Abstract
Genetic factors play a significant role in determining inflammatory bowel disease (IBD) susceptibility. Epidemiologic data support genetic contribution to the pathogenesis of IBD, which include familial aggregation, twin studies, racial and ethnic differences in disease prevalence. Linkage studies have identified several susceptibility genes contained in different genomic regions named IBD1 to IBD9. Nucleotide oligomerization domain (NOD2) and human leukocyte antigen (HLA) genes are the most extensively studied genetic regions (IBD1 and IBD3 respectively) in IBD. Mutations of the NOD2 gene are associated with Crohn's disease (CD) and several HLA genes are associated with ulcerative colitis (UC) and CD. Toll like receptors (TLRs) have an important role in the innate immune response against infections by mediating recognition of pathogen-associated microbial patterns. Studying single-nucleotide polymorphisms (SNPs) in molecules involved in bacterial recognition seems to be essential to define genetic backgrounds at risk of IBD. Recently, numerous new genes have been identified to be involved in the genetic susceptibility to IBD: NOD1/Caspase-activation recruitment domains 4 (CARD4), Chemokine ligand 20 (CCL20), IL-11, and IL-18 among others. The characterization of these novel genes potentially will lead to the identification of therapeutic agents and clinical assessment of phenotype and prognosis in patients with IBD.

- Abstract
The rate of deep wound infections in spinal lumbar fusions is around 0.7% to 11.6%, being one of the causes of morbidity in acute phase. The aim of this study was to evaluate the management of spinal infection after internal lumbar fusions. Two hundred and sixty patients, who underwent to spinal surgery with lumbar fusion and iliac bone grafting, were analized, from January 1997 to January 2005. Wound infection was observed in eight (3%) cases. The average of age was 56 years, with a higher prevalence in males (5 patients). Most prevalent was Staphylococcus aureus in 6 patients. The treatment was done by intravenous antibiotic therapy folowed by oral therapy and local irrigation. The average time of hospitalization was 35.8 days. It was possible to erradicate infection without removal of instrumentation in all patients.
