    The dependence of Brazil on imported improved papaya seeds was the main motivation for this research that primarily intended to evaluate the combining ability of eight genotypes from the 'Solo' group, crossed with eight genotypes from the 'Formosa' group following a partial diallel scheme. The traits mean fruit weight, brix degree and flavor revealed prevalence of additive effects in both genetic groups, while plant height was preponderantly additive only for the 'Solo' genotypes. On the other hand, the yield trait expressed additive superiority for the 'Formosa' genotypes. For intrapopulation breeding for higher yield, the indicated genotypes are 'Maradol' and 'Cariflora' from the 'Formosa' group as well 'Sunrise Solo 783' and 'Sunrise Solo TJ' from the 'Solo' group; but, when the objective is to breed for better fruit quality, the genotypes 'JS 12' and 'JS 11' ('Formosa' group), and 'Sunrise Solo72/12' and 'Baixinho de Santa Amália' ('Solo' group) are indicated. Based on the set of evaluated traits, the best hybrid combinations were 'Sunrise Solo 72/12 × JS 12', 'Sunrise Solo TJ × JS 12', 'Baixinho de Santa Amália × JS 12', 'Sunrise Solo TJ X JS 11' and 'Sunrise Solo 72/12 × Costa Rica'.A dependência do Brasil por sementes melhoradas de mamoeiro foi a principal motivação para a implementação deste trabalho que fundamentalmente objetivou avaliar a capacidade combinatória de oito genitores do grupo 'Solo' em cruzamento dialélico parcial com oito genótipos do grupo 'Formosa'. As características peso médio dos frutos, teor de graus brix e degustação de sabor revelaram prevalência de efeitos aditivos em ambos os grupos, ao passo que altura de planta foi preponderantemente aditiva somente para os materiais do grupo 'Solo'. Por outro lado, a produtividade expressou superioridade aditiva apenas para o grupo 'Formosa'. Para o melhoramento intrapopulacional visando maiores produtividades, são indicados os genitores 'Maradol' e 'Cariflora', do grupo 'Formosa', e 'Sunrise Solo 783' e 'Sunrise Solo TJ', do grupo 'Solo'; por sua vez, quando se visam melhorias para a qualidade do fruto, merecem destaque os genitores 'JS 12' e 'JS 11', do grupo 'Formosa', e 'Sunrise Solo 72/12' e 'Baixinho de Santa Amália', do grupo 'Solo'. Os híbridos 'Sunrise Solo 72/12 × JS 12', 'Sunrise Solo TJ × JS 12', 'Baixinho de Santa Amália × JS 12', 'Sunrise Solo TJ × JS 11' e 'Sunrise Solo 72/12 × Costa Rica' foram superiores para o conjunto de características avaliadas

    O propósito deste trabalho foi avaliar a situação periodontal de pacientes fumantes e não fumantes. Foram selecionados 64 indivíduos, sendo 24 fumantes e 40 não fumantes com idade entre 15 e 65 anos, atendidos na clínica de graduação da Universidade Federal do Maranhão - UFMA. Para os fumantes, considerou-se a quantidade diária de cigarros e o tempo de consumo. Os parâmetros clínicos avaliados foram: índice de placa, índice de sangramento gengival, profundidade de sondagem, nível de inserção clínica e recessão gengival. Os pacientes não fumantes apresentaram maiores valores para o índice de placa em todas as faces (72,24%) em relação aos fumantes (49,03%). Entretanto, as faces mesiais foram as mais comprometidas, seguidas das faces distais com valores similares em ambos os grupos. O índice de sangramento gengival foi maior no grupo de não fumantes (92,19%). O nível de inserção clínica (NIC), variando de 4 a 5 mm, apresentou resultados mais expressivos em fumantes de curta duração (53,33%), contudo os não fumantes obtiveram valores mais elevados com NIC de 6 a 7 mm (42,95%). Os não fumantes apresentaram mais sítios com recessão gengival de 2 mm (55,88%), seguido dos fumantes leves (37,25%). Concluiu-se que o fumo é um fator de risco para doença periodontal, considerando sua resposta dose-dependente. Descritores: Fumo; doenças periodontais; fator de risco.Abstract:  The aim of this study was to evaluate the periodontal status of smokers and non-smokers. A total of 64 patients were selected for the study, 24 smokers and 40 nonsmokers aged 15 to 65 years at the graduation clinics, School of Dentistry, Federal University of Maranhão – UFMA. For smokers, there were considered daily amount and consumption of cigarettes. The following clinical parameters were evaluated: plaque index, gingival bleeding index, probing depth, clinical attachment loss and gingival recession. The nonsmokers had higher values for the presence of plaque in all sites (72,24%) compared to non-smokers (49,03%), but interproximal sites were the most affected showing similar results in both groups. The gingival bleeding index presented higher in non-smokers (92,19%) compared to smokers (51,60%). The short-term smokers had higher values for probing depth or = 7 mm (10,53%). The clinical attachment loss (CAL) ranging from 4 to 5 mm showed more signifcant results in short-term smokers (53,33%), however non-smokers had higher CAL 6 mm to 7 mm (42,95%). Relative to gingival recession, non-smokers demonstrated the highest results for 2 mm (55,88%) followed by light smokers (37,25%). It has concluded that smoking is a signifcant risk factor for periodontal disease taking into account its dose-dependent response.Descriptors: Smoking, Periodontal diseases, Risk factor

    OBJECTIVES: To identify predictors of in-hospital mortality in patients with acute myocardial infarction undergoing pharmacoinvasive treatment. METHODS: This was an observational, prospective study that included 398 patients admitted to a tertiary center for percutaneous coronary intervention within 3 to 24 hours after thrombolysis with tenecteplase. ClinicalTrials.gov: NCT01791764 RESULTS: The overall in-hospital mortality rate was 5.8%. Compared with patients who survived, patients who died were more likely to be older, have higher rates of diabetes and chronic renal failure, have a lower left ventricular ejection fraction, and demonstrate more evidence of heart failure (Killip class III or IV). Patients who died had significantly lower rates of successful thrombolysis (39% vs. 68%; p = 0.005) and final myocardial blush grade 3 (13.0% vs. 61.9%; p<0.0001). Based on the multivariate analysis, the Global Registry of Acute Coronary Events score (odds ratio 1.05, 95% confidence interval (CI) 1.02-1.09; p = 0.001), left ventricular ejection fraction (odds ratio 0.9, 95% CI 0.89-0.97; p = 0.001), and final myocardial blush grade of 0-2 (odds ratio 8.85, 95% CI 1.34-58.57; p = 0.02) were independent predictors of mortality. CONCLUSIONS: In this prospective study that evaluated patients with ST-segment elevation myocardial infarction treated by a pharmacoinvasive strategy, the in-hospital mortality rate was 5.8%. The Global Registry of Acute Coronary Events score, left ventricular ejection fraction, and myocardial blush were independent predictors of mortality in this high-risk group of acute coronary syndrome patients.Universidade Federal de São Paulo (UNIFESP) Department of CardiologySecretaria de Saude do Municipio de São PauloHospital Municipal TatuapeUNIFESP, Department of CardiologySciEL

    The aim of this study was to determine the effect on the quality of life of two non-pharmacological interventions isolated or in combination: (i) passive whole-body vibration exercise (WBVE), and (ii) auriculotherapy (AT). One hundred three participants with knee osteoarthritis (KOA) were allocated to: (a) a vibration group (WBVEG; n = 17) that performed WBVE (peak-to-peak displacement: 2.5 to 7.5 mm, frequency: 5 to 14 Hz, Peak acceleration: 0.12 to 2.95 g), two days/weekly for five weeks, (b) an AT group (ATG; n = 21), stimulation of three specific auriculotherapy points (Kidney, Knee and Shenmen) in each ear pavilion, (c) WBVE + AT (WBVE + AT; n = 20) and (d) respective control groups (WBVE_CG, n = 15; AT_CG, n = 12; WBVE + AT_CG, n = 18). The participants filled out the WHOQOL-bref Questionnaire before the first and after the last sessions. Statistical differences in the various domains of the WHOQOL-bref were not found. In conclusion, WBVE or AT alone or combined did not contribute in altering the quality of life of individuals exposed to these interventions

    Acute Effects of Whole-Body Vibration Exercise on Pain Level, Functionality, and Rating of Exertion of Elderly Obese Knee Osteoarthritis Individuals: A Randomized Study

    Introduction: Among chronic diseases, knee osteoarthritis (KOA) is a joint disease that causes important progressive alterations in the articular and periarticular structures, including synovial inflammation. Exercise has been suggested as an intervention to KOA individuals, and studies suggest that whole-body vibration (WBV) exercise decreases pain levels and favours the functionality of KOA individuals. Objective: The aim of the present study is to analyze the acute effects of WBV exercise on pain levels, functionality (Timed Up and Go (TUG test), anterior trunk flexion (ATF)), and rating of exertion of elderly obese KOA individuals. Methods: Thirty-seven individuals with KOA were allocated to a WBV exercise group (WBVEG), n = 19 (15 females/4 males), and a control group (CG), n = 18 (15 females/3 males). WBVEG performed one session of WBV exercise (11 min, using 5 Hz, 2.5, 5.0, and 7.5 mm, 0.12, 0.25, and 0.37 g). Three bouts were performed (working time of 3 min and rest time of 1 min) using a side-alternating vibrating platform (VP). The same position was used in CG; however, the VP was turned off and there was equipment coupled to the VP that emitted a sound like the vibrations. The pain level was evaluated using a visual analog scale (VAS). Functionality was evaluated with a TUG test and ATF. The rating of subjectively perceived exertion was measured with the category ratio CR-10 (BORG Scale CR-10), Results: A reduction of pain levels in WBVEG after the intervention (p = 0.001) and intergroups (p = 0.041) was found. A decrease of TUG test time in both groups (p = 0.001) and intergroups (p = 0.045) was found, while no statistical changes were observed in the Borg Scale score. Significant improvements of flexibility in both groups (p = 0.001) and intergroups (p = 0.043) were found. Conclusion: One session of WBV exercise can lead to important improvements in individuals with KOA, possibly triggered by physiological responses. However, more studies are needed, in this clinical context, to confirm these results

    A list of land plants of Parque Nacional do Caparaó, Brazil, highlights the presence of sampling gaps within this protected area

    Brazilian protected areas are essential for plant conservation in the Atlantic Forest domain, one of the 36 global biodiversity hotspots. A major challenge for improving conservation actions is to know the plant richness, protected by these areas. Online databases offer an accessible way to build plant species lists and to provide relevant information about biodiversity. A list of land plants of “Parque Nacional do Caparaó” (PNC) was previously built using online databases and published on the website "Catálogo de Plantas das Unidades de Conservação do Brasil." Here, we provide and discuss additional information about plant species richness, endemism and conservation in the PNC that could not be included in the List. We documented 1,791 species of land plants as occurring in PNC, of which 63 are cited as threatened (CR, EN or VU) by the Brazilian National Red List, seven as data deficient (DD) and five as priorities for conservation. Fifity-one species were possible new ocurrences for ES and MG states
