Hypersomnia in Whipple disease: case report.

Arq Neuropsiquiatr. 2006 Sep;64(3B):865-8. Hypersomnia in Whipple disease: case report. Maia LF, Marta M, Lopes V, Rocha N, Lopes C, Martins-da-Silva A, Monteiro L. SourceDepartment of Neurological Disordes and Senses, Hospital Geral de Santo António, Largo Prof. Abel Salazar, 4099-001 Porto, Portugal. Abstract Whipple disease (WD) is a rare systemic infection caused by Tropheryma whippelii. Neurological involvement has been recognised in 40% of patients, either as initial manifestations or during the course of the disease. We report on a 45 years-old man with WD with initial, persistent and irresistible episodes of daytime somnolence. The patient was HLA-DQB1*0602 positive (genetic marker for narcolepsy). WD diagnosis was suspected on clinical and MRI basis and confirmed by histological and immunohistochemical study of duodenal biopsy. Forty months later all clinical features improved, narcoleptic-like episodes disappeared and cerebral MRI and CSF normalised. Longitudinal neurophysiological studies revealed persistent sleep pattern abnormalities with sleep fragmentation, paucity of slow wave and of REM sleep. The disruption of the hypocretin circuitry in the hypothalamic - diencephalic region triggered by the infection was the probable cause of the hypersomnia and narcopleptic symptoms. WD should be added to the list of causes of secondary hypersomnia

Redshift-Distance Survey of Early-Type Galaxies. IV. Dipoles of the Velocity Field

We use the recently completed redshift-distance survey of nearby early-type galaxies (ENEAR) to measure the dipole component of the peculiar velocity field to a depth of cz ~ 6000 km/s. The sample consists of 1145 galaxies brighter than m_B=14.5 and cz < 7000 km/s, uniformly distributed over the whole sky, and 129 fainter cluster galaxies within the same volume. Most of the Dn-sigma distances were obtained from new spectroscopic and photometric observations conducted by this project, ensuring the homogeneity of the data over the whole sky. These 1274 galaxies are objectively assigned to 696 objects -- 282 groups/clusters and 414 isolated galaxies. We find that within a volume of radius ~ 6000 km/s, the best-fitting bulk flow has an amplitude of |vbulk| =220 +/- 42 km/s in the CMB restframe, pointing towards l=304 +/- 16 degrees, b=25 +/- 11 degrees. The error in the amplitude includes statistical, sampling and possible systematic errors. This solution is in excellent agreement with that obtained by the SFI Tully-Fisher survey. Our results suggest that most of the motion of the Local Group is due to fluctuations within 6000 km/s, in contrast to recent claims of large amplitude bulk motions on larger scales.Comment: 11 pages, 2 figures, ApJL, accepted (updated results; matches accepted version

Divergência genética e correlações entre variáveis agroindustriais da população de trabalho de cajuí da Embrapa Meio-Norte.

O trabalho foi realizado na área experimental da Embrapa Meio-Norte, em Parnaíba, PI. A coleção de trabalho é constituída de 11 genótipos coletados em áreas de ocorrência natural da espécie no Estado do Piauí. O experimento foi delineado em blocos completos casualizados, com duas plantas por parcela e quatro repetições. As variáveis avaliadas foram: peso total do fruto, peso do pedúnculo, peso da castanha, diâmetros basal, diâmetro apical, comprimento, firmeza, vitamina C e sólidos solúveis totais. Utilizou-se a análise de agrupamento UPGMA para a separação dos genótipos. A análise da divergência genética permitiu separar os genótipos da coleção de trabalho do cajuí em três grupos geneticamente disjuntos e dentro destes grupos os genótipos: M28 e M21; M23 e M40A e o genótipo M17 podem fazer parte de uma composição de cruzamentos por apresentarem genes complementares para as variáveis consideradas
