Ellagic Acid prevents vascular dysfunction in small mesenteric arteries of ovariectomized hypertensive rats.

Cardiovascular diseases rank the top causes of death worldwide, with a substantial increase in women compared to men. Such increase can beexplained by the drastic decrease in 17-ß-estradiol hormone during menopause and associated with endothelium-dependent vascular dysfunction. The current treatments for cardiovascular diseases (e.g., hypertension), are only palliative and therefore, feasible, non-invasive options for preventing further vascular damage are needed. The polyphenol ellagic acid (EA) has risen as a candidate with possible vascular protection properties. This study evaluated the effects of EA in small mesenteric arteries of ovariectomized spontaneously hypertensive rats. Our findings showed that EA oral treatment for 4 weeks preserved vasodilation endothelial-dependent in acetylcholine pre-constricted arteries of spontaneously hypertensive rats to the same extent as 17-ß-estradiol treatment, an effect that was abolished in the presence of the nitric oxide synthase inhibitor L-NitroG-L-Arginine Methyl Ester. Moreover, EA induced vascular nitric oxide release, by increasing both the activitation site phosphorylation and total levels of the endothelial nitric oxide synthase. Finally, EA decreased superoxide anion while increased total levels of the antioxidant enzymes Superoxide Dismutase 2 and catalase. We concluded that EA has vasodilation properties acting via endothelial nitric oxide synthase activation and a potential antioxidant effect by stimulating the Superoxide Dismutase 2-catalase pathway.

Adaptability and stability of early carioca beans by mixed models / Adaptabilidade e estabilidade de feijão carioca precoce via modelos mistos

The genotype x environment interaction represents one of the major selection challenges due to the difficulty in identifying effectively superior genotypes. The present study aimed at estimating genetic parameters and selecting genotypes of early Carioca beans by analyzing simultaneous attributes, including yield, adaptability, and stability. In the agricultural year of 2015 and 2016, three trials were conducted, using a randomized block design, with three repetitions each, in the Agreste and Sertao regions of Pernambuco State. The genetic parameters were estimated using the mixed model procedure, and the selection was based on the harmonic mean of the relative performance of genetic values (MHPRVG, abbreviation in Portuguese) method. The environments influenced the phenotypic expression of the bean genotypes during both years, setting a specific adaptation. The mean heritability of the genotypes regarding yield exhibited low magnitude values in the trials of 2015 (5.78%) and 2016 (13.77%), indicating costly conditions for the selection of the improved genotypes. Genotype CNFC 15856 was selected, considering the genetic gain predicted for yield, by the average and specific performance in the three environments, and by the simultaneous attributes of yield, adaptability, and stability. The MHPRVG method enables the optimized selection of genotypes considering yield, stability, and adaptability; therefore, it should be included in the recommended selective criteria for agronomically superior genotypes in commercial plantations.

A interação genótipos x ambientes representa um dos maiores desafios da seleção por dificultar a identificação de genótipos efetivamente superiores. O objetivo desta pesquisa foi estimar os parâmetros genéticos e, pelos atributos simultâneos de produtividade, adaptabilidade e estabilidade, selecionar genótipos de feijão carioca precoce. No ano agrícola de 2015 e 2016, foram conduzidos três ensaios sob o delineamento de blocos casualizados com três repetições no Agreste e Sertão de Pernambuco. Os parâmetros genéticos foram estimados pelo procedimento de modelos mistos, e a seleção baseou-se no método da média harmônica do desempenho relativo dos valores genéticos. Os ambientes influenciaram na expressão fenotípica dos genótipos de feijão nos dois anos, configurando adaptação específica. A herdabilidade média dos genótipos para produtividade apresentou valores de baixa magnitude nos ensaios de 2015 (5,78%) e 2016 (13,77%), indicando condições dispendiosas para seleção dos genótipos melhorados. O genótipo CNFC 15856 foi selecionado considerando o ganho genético predito para produtividade pelo desempenho médio e específico nos três ambientes e pelos atributos simultâneos de produtividade, adaptabilidade e estabilidade. O método MHPRVG proporciona seleção otimizada de genótipos quanto à produtividade, à estabilidade e à adaptabilidade e, portanto, deve fazer parte dos critérios seletivos de recomendação de genótipos agronomicamente superiores para plantios comerciais.

Methylphenidate Alters Functional Connectivity of Default Mode Network in Drug-Naive Male Adults With ADHD.

Objective: This study evaluated the hypothesis that methylphenidate immediate release (MPH-IR) treatment would improve Default Mode Network (DMN) within-connectivity. Method: Resting-state functional connectivity of the main nodes of DMN was evaluated in a highly homogeneous sample of 18 drug-naive male adult participants with ADHD. Results: Comparing resting-state functional connectivity functional magnetic resonance imaging (R-fMRI) scans before and after MPH treatment focusing exclusively on within-DMN connectivity, we evidenced the strengthening of functional connectivity between two nodes of the DMN: posterior cingulate cortex (PCC) and left lateral parietal cortex (LLP). Conclusion: Our results contribute to the further understanding on how MPH affects functional connectivity within DMN of male adults with ADHD and corroborate the hypothesis of ADHD being a delayed neurodevelopmental disorder.

Challenges for the implementation of the chain of custody for rape victims in the Federal District / Desafíos para implantación de la cadena de custodia para víctimas de violación en el Distrito Federal / Desafios para implantação da cadeia de custódia para as vítimas de estupro no Distrito Federal

Abstract Chain of Custody implies adequate collection, recording, and storage of the vestige of sexual violence, guaranteeing the reliability of the material that will be forwarded as expert evidence. Its implementation in the Unified Health System has faced challenges. Objective: To know the attendance to victims of sexual violence in the public maternity of Federal District and evaluate the knowledge of the team about the legislation on a chain of custody. Method: Cross-sectional, quantitative, and descriptive study with 134 medical and nursing professionals working in the obstetric emergency, who answered a questionnaire, submitted to descriptive statistical analysis and the Qui-Square Test. Results: Of the 78.95% of professionals who reported attending to victims of sexual violence, 25.71% consulted in 10 minutes, and 14.18% received specific training. The situational diagnosis reveals that the care is superficial, centered on medical issues, and the collection of vestiges is non-existent. Conclusion and implications to nursing practice: A generalized change of posture is necessary so that it is possible to implant the chain of custody in the maternity studied. It is essential to develop care beyond medical issues, and which includes forensics. It is suggested a collaborative action between physicians and nurses, with nursing as the epicenter of this process.

Pleiotropic effects of Chr15q25 nicotinic gene cluster and the relationship between smoking, cognition and ADHD.

Polymorphisms in the CHRNA5-CHRNA3-CHRNB4 gene cluster (Chr15q25) have been robustly associated with nicotine dependence, including genome-wide studies, as well as with cognitive and neuropsychological measures. In addition, cognitive processes can be influenced by nicotine use through nicotinic acetylcholine receptors (nAChRs). Here, we evaluated the effect of polymorphisms in CHRNA5-CHRNA3-CHRNB4 gene cluster and their interaction with tobacco smoking status on cognition in patients with Attention Deficit/Hyperactivity Disorder (ADHD). Eight SNPs from the CHRNA5-CHRNA3-CHRNB4 gene cluster were evaluated on a clinical sample of 403 adults with ADHD. Cognitive performance was assessed using the Wechsler Adult Intelligence Scale-Revised (WAIS-R). Analyses of covariance were used to assess the influence of single markers and their interaction with smoking status in the Vocabulary and Block Design subtests of WAIS-R. Correction for multiple comparisons was applied. Lifetime smoking was associated to Vocabulary subtest. The TT genotypes of CHRNA5 SNPs rs588765 and rs514743 showed a trend towards association with, respectively, higher and lower scores on the Vocabulary subtest. There was a significant interaction between intergenic SNP rs8023462 and smoking on Vocabulary scores. Our results are consistent with an influence of variants in the CHRNA5-CHRNA3-CHRNB4 gene cluster on cognitive measures. The overall scenario suggests a pleiotropic role of Chr15q25 nicotinic gene cluster with complex influences in ADHD, tobacco smoking and cognitive performance, characteristics that can be partially interdependent and may share underlying genetic factors.

Does collateral retrospective information about childhood attention-deficit/hyperactivity disorder symptoms assist in the diagnosis of attention-deficit/hyperactivity disorder in adults? Findings from a large clinical sample.

OBJECTIVES: In accordance with consolidated clinical practice, Diagnostic and Statistical Manual of Mental Disorders, 5th edition suggests a key role of collateral information in the evaluation of retrospective childhood attention-deficit/hyperactivity disorder symptoms in adults despite poor evidence supporting its use. This study aims to assess the incremental value of collateral information on the presence of childhood attention-deficit/hyperactivity disorder symptoms when evaluating adults with attention-deficit/hyperactivity disorder. METHODS: Adult patients with attention-deficit/hyperactivity disorder (n = 449) and non-attention-deficit/hyperactivity disorder subjects (n = 143) underwent an extensive clinical assessment based on Diagnostic and Statistical Manual of Mental Disorders, 4th edition criteria. For patients, retrospective collateral information regarding childhood attention-deficit/hyperactivity disorder was obtained and used to sort them into two groups: agreement (n = 277) and disagreement (n = 172) between self- and collateral reports. We compared demographic, clinical and response to treatment profiles among groups to test the relevance of collateral information on the specific issue of childhood attention-deficit/hyperactivity disorder symptoms. RESULTS: Both attention-deficit/hyperactivity disorder groups had higher rates of several comorbidities (oppositional defiant, conduct, substance use and bipolar disorders; all p < 0.001) and impairments than controls. Disagreement between self- and collateral reports on childhood attention-deficit/hyperactivity disorder symptoms occurred in 38% of patients. Overall, attention-deficit/hyperactivity disorder disagreement and agreement groups had similar profiles in response to treatment and comorbidity, and the few differences detected in impairment measures were of small magnitude (Eta(2) < 0.05). CONCLUSION: Although collateral report has an important role for diagnosing attention-deficit/hyperactivity disorder in children, it has no incremental value in the evaluation of childhood attention-deficit/hyperactivity disorder symptoms in adults with a self-reported history of attention-deficit/hyperactivity disorder assessed in clinical settings.

Analysis of laser therapy and assessment methods in the rehabilitation of temporomandibular disorder: a systematic review of the literature.

The aim of the present study was to perform a systematic review of the literature on the effects of low-level laser therapy in the treatment of TMD, and to analyze the use of different assessment tools. [Subjects and Methods] Searches were carried out of the BIREME, MEDLINE, PubMed and SciELO electronic databases by two independent researchers for papers published in English and Portuguese using the terms: "temporomandibular joint laser therapy" and "TMJ laser treatment". [Results] Following the application of the eligibility criteria, 11 papers were selected for in-depth analysis. The papers analyzed exhibited considerable methodological differences, especially with regard to the number of sessions, anatomic site and duration of low-level laser therapy irradiation, as well as irradiation parameters, diagnostic criteria and assessment tools. [Conclusion] Further studies are needed, especially randomized clinical trials, to establish the exact dose and ideal parameters for low-level laser therapy and define the best assessment tools in this promising field of research that may benefit individuals with signs and symptoms of TMD.

Severity but not comorbidities predicts response to methylphenidate in adults with attention-deficit/hyperactivity disorder: results from a naturalistic study.

Although the identification of reliable predictors of methylphenidate response in adults with attention-deficit/hyperactivity disorder (ADHD) is necessary to guide treatment decisions, very few data exist on this issue. Here, we assessed the predictors of clinical response to immediate-release methylphenidate hydrochloride (IR-MPH) in a naturalistic setting by analyzing the influence of demographic factors, severity, and a wide range of comorbid psychiatric disorders. Two hundred fifty adult patients with ADHD were evaluated and completed a short-term treatment with IR-MPH. Mental health diagnoses were based on Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria through the use of standard structured interviews. The Swanson, Nolan, and Pelham Rating Scale, version 4, adapted to adults was used to assess the severity of ADHD. In the linear regression model, only higher severity of ADHD was associated to a better IR-MPH response (b = 0.770; P < 0.001). Treatment of comorbidities in a subsample (n = 62) did not modify this pattern. Our findings suggest that in clinical settings, patients with more severe ADHD symptoms have a good response to treatment independently from the presence of mild or stabilized comorbidities and their treatments. For adults with ADHD, differently from other common psychiatric disorders such as depression and anxiety, higher severity is associated with better treatment response.

ADHD diagnosis may influence the association between polymorphisms in nicotinic acetylcholine receptor genes and tobacco smoking.

Polymorphisms in the CHRNA5-CHRNA3-CHRNB4 gene cluster have been shown to be involved in tobacco smoking susceptibility. Considering that attention deficit/hyperactivity disorder (ADHD) not only increases the risk but may also influence the molecular mechanisms of tobacco smoking, we analyzed the association between polymorphisms in the nicotinic acetylcholine receptor genes and tobacco smoking among individuals with or without ADHD. The sample included 1,118 subjects divided into four groups according to smoking status and ADHD diagnosis. Our results demonstrate that the minor alleles of two polymorphisms (rs578776 and rs3743078) in the CHRNA3 gene are associated with an increased risk of tobacco smoking only among patients with ADHD. These alleles have been shown in previous studies to be protective factors for smoking in subjects without ADHD. These findings add to existing evidence that ADHD may exert an important modifying effect on the genetic risk of smoking and should be considered in tobacco smoking association studies.

Could comorbid bipolar disorder account for a significant share of executive function deficits in adults with attention-deficit hyperactivity disorder?

OBJECTIVE: The frequent comorbidity between attention-deficit hyperactivity disorder (ADHD) and bipolar disorder (BD) represents a challenge for disentangling specific impairments of each disorder in adulthood. Their functional impairments seem to be mediated by executive function deficits. However, little is known about the extent to which each executive function deficit might be disorder specific or explained by the comorbidity. The aim of the present study was to determine if comorbid BD could account for a significant share of executive function deficits when measured by the Wisconsin Card Sorting Test (WCST) in adults with ADHD. METHODS: Adult patients with ADHD and healthy subjects were evaluated in the ADHD outpatient Program at the Hospital de Clínicas de Porto Alegre. Psychiatric diagnoses were based on DSM-IV criteria. WCST scores were compared by multivariate analysis of covariance among three groups: ADHD with BD (n = 51), ADHD without BD (n = 278), and healthy subjects (n = 91). RESULTS: When compared to patients without BD and healthy subjects, patients with ADHD and comorbid BD showed lower scores in total correct answers (p = 0.003); higher scores in total errors (p = 0.004) and non-perseverative errors (p = 0.002); and completed fewer categories (p = 0.009). Patients with ADHD without BD did not differ from healthy subjects. CONCLUSIONS: WCST impairments among patients with ADHD seem to be to a large extent attributable to comorbid BD. Although other executive function deficits (e.g., in the inhibitory control domain) have been demonstrated to accompany ADHD, the present findings suggest that set-shifting deficits are strongly related to comorbid BD.

Adequacy of methodology for germination of diaspores of barauna, Schinopsis brasiliensis (Anacardiaceae) / Adequação da metodologia para germinação de diásporos de baraúna, Schinopsis brasiliensis (Anacardiaceae)

Schinopsis brasiliensis Engl. (Anacardiaceae) is a typical "Caatinga" (savanna) tree, whose seed germination occurs in a slow and irregular. The ideal conditions for seed germination of many tree species are still unknown. The present study objective was to evaluate different temperatures and substrates to establish a protocol for seed germination Schinopsis brasiliensis, conducted at the Federal University of Paraiba, Areia, Paraiba State (PB), Brazil. Therefore, different temperatures (25, 30, 35 and 20-30 ºC) and substrates (including sand, vermiculite between, on paper, between paper and paper roll) were used. To assess the effect of treatments for germination (%), first germination count (%), germination velocity index (GSI), lengths of the principal root and of the aerial portion of the seedlings and dry weights of the root system and of the aerial portion of the seedlings. The experimental design was completely randomized with treatments arranged in a 4 x 5 factorial arrangement (temperature and substrate), four replicates of 25 diaspores for each treatment. The means were compared by Tukey test at 1% probability and orthogonal contrasts between temperatures (35 vs 30 º C, 30 vs 25 º C and 20-30 vs 30 º C). The germination tests of S. brasiliensis should analyze the numbers of seedlings germinated 10 (first count) and 20 days (final evaluation) after sowing; The combination of a vermiculite substrate and alternating temperature (20-30 ºC) was best for stimulating the germination of S. brasiliensis diaspores.

Schinopsis brasiliensis Engl. (Anacardiaceae) é uma árvore típica da caatinga, cuja germinação das sementes ocorre de forma lenta e irregular. As condições ideais de germinação das sementes de muitas espécies ainda não são bem conhecidas. O presente estudo teve como objetivo avaliar diferentes temperaturas e substratos para o estabelecimento de um protocolo de germinação para sementes de Schinopsis brasiliensis, conduzido na Universidade Federal da Paraíba, em Areia-PB. Para tanto, foram utilizados diferentes temperaturas (25, 30, 35 e 20-30 ºC) e substratos (entre areia, entre vermiculita, sobre papel, entre papel e rolo de papel). Para avaliação do efeito dos tratamentos foram realizados testes de germinação (%), primeira contagem de germinação (%), índice de velocidade de germinação (IVG), comprimento da raiz principal e da parte aérea das plântulas e massa seca do sistema radicular e da parte aérea das plântulas. O delineamento experimental utilizado foi o inteiramente ao acaso, com os tratamentos distribuídos em arranjo fatorial 4 x 5 (temperaturas e substratos), em quatro repetições de 25 diásporos para cada tratamento. As médias foram comparadas pelo teste de Tukey, ao nível de 1% de probabilidade e por contrastes ortogonais entre temperaturas (35 vs 30 ºC, 30 vs 25 ºC e 20-30 vs 30 ºC). Para o teste de germinação de S. brasiliensis, as plântulas devem ser analisadas aos 10 (primeira contagem) e 20 dias (avaliação final) do semeio; O substrato vermiculita e a temperatura alternada 20-30 ºC são mais indicados para a germinação dos diásporos e o desenvolvimento inicial de plântulas de S. brasiliensis. A temperatura constante de 35 ºC é prejudicial à germinação dos diásporos de S. brasiliensis.

Genética além dos rótulos / Genetics beyond labels

A genética, ao longo de sua história, foi frequentemente vinculada a conceitos de imutabilidade e determinismo. Entretanto, o pertinente reconhecimento das interações complexas entre genes e ambiente apresenta-se como fundamental para o desenvolvimento de uma concepção não determinista do comportamento e dos transtornos mentais. Para contextualizar a visão sobre a genética psiquiátrica na área da saúde mental, discutimos, a partir de recortes históricos, o uso dessa ciência como justificativa para ações fora dos limites éticos. Além disso, trabalhamos a concepção da genética além dos rótulos, apresentando a questão da causa em transtornos mentais com uma abordagem centrada na interação gene x ambiente. Essa concepção está ligada à ideia de complexidade e heterogeneidade em oposição ao reducionismo determinista. Por fim, propomos uma abordagem integrada, apontando a necessidade de novos modelos que levem em consideração o caráter multifatorial dos transtornos mentais. Esses modelos podem não apenas auxiliar no entendimento das doenças, mas também no desenvolvimento de estratégias de prevenção e tratamento que minimizem o sofrimento advindo desses transtornos.(AU)

Genetics has been frequently linked to concepts of immutability and determinism throughout its history. However, the necessary acknowledgement of complex interactions between genes and environment is essential for the development of a non-determinist conception of behavior and mental disorders. In order to contextualize the scope of psychiatric genetics in the field of mental health, the way genetics was used as justification to unethical attitudes was discussed through a historical perspective. Besides that, we attempted to conceptualize genetics beyond labels, presenting the issue of cause in mental disorders through an approach centered in the gene vs. environment interaction. This conception is linked to the idea of complexity and heterogeneity as opposed to determinist reductionism. As a conclusion, we suggest an integrated approach pointing to the need of new models that consider the multifactorial character of mental disorders. Furthermore, these models can not only help in the understanding of diseases, but also in the development of prevention and treatments strategies that could minimize the suffering brought by these disorders.(AU)

Germinação e vigor de sementes de Clitoria fairchildiana R. A. Howard. - Fabaceae em função da coloração do tegumento e temperaturas / Seed germination and vigor of Clitoria fairchildiana R. A. Howard. fabaceae-depending on the coloration of seedcoat and temperatures

Clitoria fairchildiana Howard, nativa da região amazônica é bastante utilizada em programas de reflorestamento, na arborização de ruas, praças públicas, rodovias e estacionamentos devido à sua copa larga e frondosa e ao seu rápido crescimento. Diante de sua importância realizou o trabalho com o objetivo de estudar a influência da coloração do tegumento e da temperatura na germinação e vigor de sementes de C. fairchildiana. A pesquisa foi conduzida no Laboratório de Análise de Sementes, do Centro de Ciências Agrárias, da Universidade Federal da Paraíba, em Areia - PB. Avaliou-se a germinação das sementes marrons e pretas em temperaturas constantes (25, 30 e 35 °C) e alternada (20- 30 °C). O delineamento experimental foi inteiramente ao acaso, em esquema fatorial 2 x 4 (coloração e temperaturas), em quatro repetições. As variáveis analisadas foram: germinação, índice de velocidade de germinação (IVG), comprimento e massa seca de plântulas. A qualidade fisiológica das sementes de Clitoria fairchildiana de coloração preta é inferior comparativamente à de coloração marrom, independentemente da temperatura utilizada para sua avaliação.

Clitoria fairchildiana Howard, a native of the Amazon region is widely used in programs of reforestation, afforestation, streets, public squares, roads and parking lots due to its large and leafy cup and its rapid growth. Before its significance was the work with the goal of studying the influence of coloured tegument and temperature on the germination and vigor of seeds of C. fairchildiana. The survey was conducted in the laboratory of analysis of seed from the center of Agrarian Sciences, Federal University of Paraíba, in Areia-PB. Assessed the germination of seeds and brownish black in constant temperatures (25, 30 and 35 °C) and alternating (20-30 °C). The experimental design was entirely at random, in schema factorial 2 x 4 (staining and temperatures), four repetitions. The variables analyzed were: sprouting, germination speed index (IVG), length and mass seedling drought. The physiological quality of seeds of Clitoria fairchildiana black staining is less compared to Brown in colour, regardless of the temperature used for their assessment.

Cognitive deficits in adults with ADHD go beyond comorbidity effects.

OBJECTIVE: This study addresses if deficits in cognitive, attention, and inhibitory control performance in adults with ADHD are better explained by the disorder itself or by comorbid conditions. METHOD: Adult patients with ADHD (n = 352) and controls (n = 94) were evaluated in the ADHD program of a tertiary hospital. The diagnostic process for ADHD and comorbidities was based on Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV) criteria. Stepwise regression analyses evaluated the effect of ADHD, demographics, and comorbidities on the scores from Wechsler Adult Intelligence Scale-Revised, Continuous Performance Test, and Stroop Color and Word Test. RESULTS: Patients with ADHD of both genders had worse performance on neuropsychological domains, even after adjustment for comorbidities. The presence of comorbid bipolar disorder and specific phobia are associated with more Stroop errors, whereas patients with generalized anxiety disorder present a longer execution time in Stroop. CONCLUSION: Neuropsychological deficits in adults with ADHD go beyond comorbidity. Specific comorbid disorders may influence the neuropsychological functioning in adults with ADHD.

Clitoria fairchildiana Howard, nativa da região amazônica, é bastante utilizada em programas de reflorestamento, na arborização de ruas, praças públicas, rodovias e estacionamentos, devido à sua copa larga e frondosa e ao seu rápido crescimento. Dessa forma, o objetivo neste trabalho foi estudar a influência de regimes de luz e temperaturas na germinação e no vigor de sementes de C. fairchildiana. Avaliou-se o potencial fisiológico das sementes sob temperaturas constantes (25 e 30°C) e alternada (20-30°C) em diferentes regimes de luz: branca, verde, vermelho-distante, vermelha e ausência de luz. O delineamento experimental foi inteiramente casualizado, em esquema fatorial 3x5, em quatro repetições. As variáveis analisadas foram: porcentagem de germinação, primeira contagem e índice de velocidade de germinação (IVG), bem como comprimento e massa seca de parte aérea e raízes das plântulas. As sementes de C. fairchildiana germinam no escuro e em todos os regimes de luz, independente da temperatura utilizada, sendo consideradas fotoblásticas neutras. Para avaliação do vigor dessas sementes, recomenda-se a temperatura de 30°C no regime de luz branca.

Clitoria fairchildiana Howard, a native of the Amazon region is widely used in reforestation programs, planting trees in the streets, public squares, roads and parking lots because of its broad and leafy canopy and its rapid growth. Thus, the objective was to study the influence of light and temperature regimes on germination and vigor of C. fairchildiana seeds. We evaluated the physiological potential of seeds under constant temperatures (25 and 30°C) and alternating (20-30°C) in different light regimes: white, green, far-red, red and darkness. The experimental design was completely randomized in a factorial 3x5, with four replications. The variables analyzed were: germination percentage, first count and germination speed index (GSI), as well as length and dry mass of shoots and primary roots of seedlings. C. fairchildiana seeds germinate in the dark and in all light regimes, regardless of the temperature used and are considered neutral photoblastic. To evaluate the effect of these seeds is recommended temperature of 30°C in the regime of white light, except for the test seedling dry weight, which indicated the green light, far-red or dark.

The role of a lifetime history of oppositional defiant and conduct disorders in adults with ADHD: implications for clinical practice.

INTRODUCTION: Attention-deficit/hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), and conduct disorder (CD) are frequently co-occurring disorders in children and adolescents. However, their clinical status among adults is still under discussion. This study analyzes how the current clinical presentation of adult ADHD might be influenced by a lifetime history of CD and ODD. METHODS: We compared three groups of patients: ADHD without history of CD/ODD (n = 178), ADHD + history of ODD (n = 184), and ADHD + history of CD (n = 96). RESULTS: A history of CD (and to a lower extent ODD) is associated with a more severe and externalizing profile. CONCLUSION: Past CD and ODD entail a significant negative mental health impact on persistent ADHD, reinforcing the importance of actively assessing the developmental history of adult ADHD patients.

Does age of onset of impairment impact on neuropsychological and personality features of adult ADHD?

The consideration of age of onset of impairment as part of the ADHD diagnosis is controversial and has been a revisited issue with the emergence of the new classifications in Psychiatry. The aim of this study is to compare patients with early and late onset of ADHD impairment in terms of neuropsychological and personality characteristics. Adult patients with ADHD (n = 415) were evaluated in the ADHD outpatient program at Hospital de Clínicas de Porto Alegre, Brazil. The diagnostic process for ADHD and comorbidities was based on DSM-IV criteria. The comparison between the two ages of onset groups (before 7; n = 209 or from 7 to 12 years; n = 206) was performed with ANOVA, followed by Stepwise forward regression analyses to restrict the number of comparisons and access the possible effect of multiple confounders. Patients with early onset ADHD present higher scores in novelty seeking in both analyses (respectively P = 0.016 and P = 0.002), but similar cognitive and attention features as compared with the late onset group. These data add to previous evidence that despite a more externalizing profile of early onset ADHD, the overall performance is similar reinforcing the need for awareness and inclusion of the late onset group in DSM-V diagnostic criteria.

Germinação e vigor de sementes de Sapindus saponaria L. submetidas a tratamentos pré-germinativos, temperaturas e substratos / Germination and vigor of Sapindus saponaria L. seeds submitted pre-germinative treatments, temperatures and substrates

Sapindus saponaria L. é uma árvore de grande porte distribuída especialmente na região Amazônica, sendo de grande importância para o reflorestamento de áreas degradadas, na construção civil e confecção de brinquedos. O objetivo dessa pesquisa foi testar tratamentos pré-germinativos para superar a dormência e avaliar o efeito da temperatura e do substrato na germinação das sementes de S. saponaria. O experimento foi conduzido em ambiente protegido e no Laboratório de Análise de Sementes (LAS) da Universidade Federal da Paraíba. Dois ensaios foram desenvolvidos, sendo no primeiro testados os seguintes tratamentos: imersão das sementes em ácido sulfúrico (H2SO4) por 0, 15, 30, 45 e 60 minutos, analisando-se as variáveis: emergência e índice de velocidade de emergência, comprimento e massa seca de plântulas. No segundo ensaio foi avaliado o efeito das temperaturas (25, 20-30, 30 e 35°C) e substratos (areia, vermiculita e pó-de-coco) na germinação e no vigor das sementes. Pelos resultados constata-se que a imersão das sementes de S. saponaria em ácido sulfúrico por 60 minutos é suficiente para superar a dormência acelerando e uniformizando a emergência das plântulas. A melhor condição para executar o teste de germinação é empregando temperatura constante de 30°C ou alternada de 20-30°C em substrato vermiculita ou apenas 30°C combinado com o substrato areia.

Sapindus saponaria L. is a large tree distributed especially in the Amazon region is of great importance for the reforestation of degraded areas, construction and manufacture of toys. The aim of this study was to test pre-germination treatments to overcome dormancy and to evaluate the effect of temperature and substrate on seed germination of S. saponaria. The experiment was conducted in a protected ambient and the Seed Analysis Laboratory (SAL), Universidade Federal da Paraíba. Two tests were developed, and tested first in the following treatments: seeds immersion in sulfuric acid (H2SO4) for 0, 15, 30, 45 and 60 minutes, analyzing the variables: emergence and emergence speed index, length and dry mass of seedlings. In the second test, was evaluated the effect of temperatures (25, 20-30, 30 and 35°C) and substrates (sand, vermiculite and coconut dust) on the germination and seed vigor. From the results it appears that the immersion of seeds of S. saponaria in sulfuric acid for 60 minutes is sufficient to overcome dormancy accelerating and standardizing the seedling emergency. The best conditions for testing germination using constant temperature of 30°C or alternating 20-30°C in vermiculite or only 30°C combined with the sand.
