Intra-individual stability of neuromotor tasks from 6 to 18 years: a longitudinal study.

This study investigates the intra-individual stability of the speed of several motor tasks and the intensity of associated movements in 256 children (131 girls, 125 boys) from the Zurich generational study using the Zurich neuromotor assessment battery (ZNA) over a 12-year period from the age of 6 to 18 years. The stability was assessed by correlograms of standard deviation scores calculated from age- and gender-adjusted normative values and compared with standing height and full scale intelligence quotient (IQ). While motor tasks of hand, finger and foot (HFT) and contralateral associated movements (CAM) exhibited a moderate stability (summary measure as correlation coefficients between two measurements made 4 years apart: .61 and .60), other tasks (dynamic balance, static balance and pegboard) were only weakly stable (.46, .47 and .49). IQ and height were more stable than neuromotor components (.72 and .86). We conclude that the moderately stable HFT and CAM may reflect "motor traits", while the stability of the pegboard and balance tasks is weaker because these skills are more experience related and state-dependent.

Functional studies of a germ-line polymorphism at codon 47 within the p53 gene.

A rare germ-line polymorphism in codon 47 of the p53 gene replaces the wild-type proline (CCG) with a serine (TCG). Restriction analysis of 101 human samples revealed the frequency of the rare allele to be 0% (n = 69) in Caucasians and 4.7% (3/64, n = 32) among African-Americans. To investigate the consequence of this amino acid substitution, a cDNA construct (p53 mut47ser) containing the mutation was introduced into a lung adenocarcinoma cell line (Calu-6) that does not express p53. A growth suppression similar to that obtained after introduction of a wild-type p53 cDNA construct was observed, in contrast to the result obtained by introduction of p53 mut143ala. Furthermore, expression of neither p53 mut47ser nor wild-type p53 was tolerated by growing cells. In transient expression assays, both mut47ser and wild-type p53 activated the expression of a reporter gene linked to a p53 binding sequence (PG13-CAT) and inhibited the expression of the luciferase gene under the control of the Rous sarcoma virus promoter (RSVluc). In the same assay, mut143ala did not activate the expression of PG13-CAT and produced only a slight inhibitory effect on RSVluc. These findings indicate that the p53 variant with a serine at codon 47 should be considered as a rare germ-line polymorphism that does not alter the growth-suppression activity of p53.

Câncer gástrico precoce: revisão de 47 casos do instituto nacional de câncer nos últimos cinco anos

OBJETIVO: O presente estudo visa estudar as características dos tumores gástricos precoces diagnosticados em um grande centro de referência no tratamento do câncer gástrico em nosso país, o Instituto Nacional de Câncer. MÉTODO: Analisamos retrospectivamente os casos de câncer gástrico precoce da Seção de Cirurgia Abdominopélvica do Hospital do Câncer I no período de 1995 a 1999. Resgatamos 47 prontuários de pacientes portadores de câncer gástrico precoce, dos 296 pacientes submetidos à ressecção gástrica neste período. RESULTADOS: Em nosso hospital a incidência corresponde a cerca de 15,8% dos pacientes submetidos a gastrectomias por câncer gástrico. Constatamos uma incidência de 1,1:1 com relação ao sexo F/M e com morbidade de 19,1% e mortalidade de 4,2%. Houve uma predominância do tipo IIc + III e com 27,6% de positividade para o Helicobacter pylori. CONCLUSÃO: O câncer gástrico precoce representa o melhor estágio para a ressecção nos tumores do estômago, porém, infelizmente, ainda é pouco diagnosticado em nosso meio, apesar dos avanços nos métodos de diagnóstico.
