Após muita discussão e duas reuniões das lideranças partidárias, foi aprovado na Comissão de Sistematização o projeto da nova Constituição. Fernando Henrique Cardoso (PMDB-SP) diz que houve acordo entre as lideranças para a votação do projeto formulado por Bernardo Cabral (PMDB-AM). Sandra Cavalcanti (PFL-RJ) fez críticas ao trabalho de Bernardo Cabral, mas depois desmentiu o que foi divulgado pela imprensa. Afonso Arinos (PFL-RJ) lê nota citando o desmentido e dando integral apoio ao Relator Bernardo Cabral. Gasthone Righi (PTB-SP) quer que a Comissão de Sistematização continue apreciando as emendas dos constituintes. Cronograma dos trabalhos na Assembleia Nacional Constituinte (ANC) : discussão e apresentação de emendas no dia 14 de julho; fim do prazo para apresentar emendas no dia 14 de agosto; encerramento da primeira fase de discussão em Plenário no dia 24 de Agosto ; a Comissão de Sistematização volta a discutir o projeto no dia 25 de agosto; encerramento do prazo para votação do substitutivo na Comissão de Sistematização no dia 20 de Setembro; início da votação em 1º turno no Plenário no dia 23 de setembro. Se todos os prazos forem cumpridos, a nova Constituição será promulgada ainda em 1987 e entrará em vigor no dia 1º de janeiro de 1988. Percival Muniz (PMDB-MT) incentiva a população a participar dos debates da Assembleia Constituinte.

The Nutrient Enhanced Coastal Ocean Productivity (NECOP) Program is a component of NOAA's Coastal Ocean Program. The central hypothesis of this research is: Anthropogenic nutrient inputs have enhanced coastal ocean productivity with subsequent impacts on coastal ocean water quality, living resource yields, and the global marine carbon cycle. The initial study area for this program is the Mississippi/Atchafalaya River Outflow and adjacent Louisiana shelf region.

BRCA1 has been implicated in numerous DNA repair pathways that maintain genome integrity, however the function responsible for its tumor suppressor activity in breast cancer remains obscure. To identify the most highly conserved of the many BRCA1 functions, we screened the evolutionarily distant eukaryote Saccharomyces cerevisiae for mutants that suppressed the G1 checkpoint arrest and lethality induced following heterologous BRCA1 expression. A genome-wide screen in the diploid deletion collection combined with a screen of ionizing radiation sensitive gene deletions identified mutants that permit growth in the presence of BRCA1. These genes delineate a metabolic mRNA pathway that temporally links transcription elongation (SPT4, SPT5, CTK1, DEF1) to nucleopore-mediated mRNA export (ASM4, MLP1, MLP2, NUP2, NUP53, NUP120, NUP133, NUP170, NUP188, POM34) and cytoplasmic mRNA decay at P-bodies (CCR4, DHH1). Strikingly, BRCA1 interacted with the phosphorylated RNA polymerase II (RNAPII) carboxy terminal domain (P-CTD), phosphorylated in the pattern specified by the CTDK-I kinase, to induce DEF1-dependent cleavage and accumulation of a RNAPII fragment containing the P-CTD. Significantly, breast cancer associated BRCT domain defects in BRCA1 that suppressed P-CTD cleavage and lethality in yeast also suppressed the physical interaction of BRCA1 with human SPT5 in breast epithelial cells, thus confirming SPT5 as a relevant target of BRCA1 interaction. Furthermore, enhanced P-CTD cleavage was observed in both yeast and human breast cells following UV-irradiation indicating a conserved eukaryotic damage response. Moreover, P-CTD cleavage in breast epithelial cells was BRCA1-dependent since damage-induced P-CTD cleavage was only observed in the mutant BRCA1 cell line HCC1937 following ectopic expression of wild type BRCA1. Finally, BRCA1, SPT5 and hyperphosphorylated RPB1 form a complex that was rapidly degraded following MMS treatment in wild type but not BRCA1 mutant breast cells. These results extend the mechanistic links between BRCA1 and transcriptional consequences in response to DNA damage and suggest an important role for RNAPII P-CTD cleavage in BRCA1-mediated cancer suppression.

La grande scène au trait est celle du jugement du chapitre 125 du Livre des Morts. On y voit le défunt devant la déesse Maât, la balance où le coeur est pesé sous la surveillance d'Anubis, Horus et Thot en sa qualité de scribe. La grande dévoreuse est présente, devant Osiris, lequel est assis sur son trône.Texte :Col. 1, 1-14 et vignette : chapitre 137 A avec titre rubriqué : "Formule des quatres torches". La vignette montre le défunt assis entouré de quatre lampes.Col. 1, 15-25 et vignette : chapitre 138 avec titre rubriqué : "Formule pour entrer en Abydos". Le défunt est debout devant deux enseignes.Col. 2 et vignette : chapitre 141 avec titres rubriqués : "Formule pour connaître le nom des dieux du ciel méridional; Livre pour transfigurer les esprits, pour les dieux du ciel méridional et les dieux du ciel septentrional, et les dieux qui sont dans la nécropole septentrionale, et les dieux qui conduisent dans la Douat, que l'on fait pour un homme, pour son père ou pour sa mère lors de la fête ; pour le glorifier dans le coeur de Rê et dans le coeur des dieux, de sorte qu'il soit avec eux. La vignette montre le défunt en adoration derrière Horus qui présente le signe de la vie à Osiris.
