Threshold behavior in metastable dissociation of multi-photon ionized thymine and uracil
Microsecond-timescale HNCO loss has been observed from single-color multi-photon ionized pyrimidine nucleobases in the gas phase. Photon energy thresholds for the metastable channels have been measured at 5.55 ± 0.02 eV for thymine and 5.57 ± 0.02 eV for uracil. We argue that these results can be attributed to accessing the molecules’ S1 states with additional vibrational energy matching the threshold energy for HNCO loss from the radical cation. Combined with previous photoionization energies, this enables the S1 adiabatic energies to be deduced: 3.67 ± 0.07 eV for thymine and 3.77 ± 0.07 eV for uracil. These values are consistent with recent calculations

Interferência do déficit hídrico na produtividade e acúmulo de sólidos solúveis em genótipos de milho contrastantes a seca.
Avaliação do perfil fenotípico de caprinos brasileiros e africanos.
Resumo: Objetivou-se diferenciar populações caprinas brasileiras e cabo-verdianas (n=1084) por meio de descritores biométricos e comparação com raças comerciais. Foram avaliadas sete características de fêmeas adultas, através da estatística descritiva, análise de variância, teste de multicolinearidade, distância generalizada de Mahalanobis (D2) e algoritmo UPGMA. Após o teste de multicolinearidade foi identificada e descartada a variável profundidade torácica. O maior valor da D2 foi entre as populações Nambi e Mambrina (D2=93,78), e a menor D2 foi entre as cabras cabo-verdianas de Santo Antão e São Vicente (D2=0,41). O dendrograma colocou as raças Mambrina e Anglo-Nubiana a parte das demais. As cabras de Cabo Verde ficaram mais próximas das brasileiras de núcleos de conservação. As caboverdianas se agruparam segundo Barlavento e Sotavento. A eficácia da manutenção dos caprinos brasileiros em rebanhos de conservação nos faz preconizar tais iniciativas como ferramenta eficaz de manutenção dos recursos genéticos para potencial uso sustentável. Evaluation of the phenotypic profile of Brazilian and African goats. Abstract: The work aims was differentiate Brazilian goats populations of Cape Verdean (n = 1084) using biometric descriptors and comparison with commercial breeds. It was measured seven characteristics of female adult goats by using descriptive statistics, analysis of variance test multicollinearity, Mahalanobis distance (D2) and UPGMA algorithm. After testing of multicollinearity was identified and discarded the thoracic depth variable. The maximum value of D2 was between populations Nambi and Mambrina (D2 = 93.78), and the lower D2 was between the Cape Verdean goats of Santo Antão and São Vicente (D2 = 0.41). The dendrogram put the breeds Mambrina and Anglo-Nubian part of others. The goats of Cape Verde were closer to the Brazilian conservation nuclei. The Cape Verdean were made a group was Barlavento and Sotavento. The maintenance efficiency of the Brazilian goat herds conservation makes us valuate such initiatives as an effective tool for maintenance of genetic resources for potential use sustainable
Leprosy presenting as remitting seronegative symmetrical synovitis with pitting oedema syndrome - a case report
Background: Leprosy typically manifests with skin and peripheral nerve involvement. Musculoskeletal complaints are the third most common, and can be the sole presenting manifestation. They range from arthralgia/arthritis in reactional states to full mimics of systemic rheumatic diseases. Remitting Seronegative Symmetrical Synovitis with Pitting Oedema syndrome has only been described once in a patient with already diagnosed Leprosy.
Case report: A 68-year-old male, from an endemic region of familial amyloid polyneuropathy, presented with an inaugural Remitting Seronegative Symmetrical Synovitis with Pitting Oedema like syndrome, more that 20 years after travelling to Leprosy endemic areas. Arthritis would resurface whenever oral prednisone was tapered, so methotrexate was started, controlling the complaints. Only one year later, after the appearance of peripheral neuropathy and skin lesions, it was possible to diagnose Leprosy, through the identification of Mycobacterium leprae bacilli in a peripheral nerve biopsy.
Conclusion: This report is an example of the heterogeneity of manifestations of Leprosy, namely rheumatic, and the challenge of diagnosing it when typical complaints are absent. It is also a reminder that this disease should be considered whenever a patient with a combination of skin/neurologic/rheumatic complaints has travelled to endemic countries in the past.info:eu-repo/semantics/publishedVersio
Aceitabilidade sensorial do néctar misto de araçá-boi com manga.
O araçá-boi (Eugênia Stipitata, McVaugh), fruta originária do oeste amazônico, possui polpa suculenta e bastante ácida, o que restringe seu consumo in natura. Sua polpa tem sido utilizada para produção de sorvetes, geleias e néctares, quando associada com frutas de baixa acidez (SOUZA FILHO et al., 2002). Com o intuito de introduzir melhor aproveitamento desse fruto na indústria de alimentos, além de contribuir para a agregação de valor destas culturas, este estudo objetivou avaliar a aceitação sensorial de diferentes formulações de néctar misto de araçá-boi com manga.pdf 222
