Description of lithofacies associations and their interpreted settings from sequences of sediment core CRP-1 (Table 2)

Cape Roberts Project drillcore 1 was obtained from Roberts Ridge, a sea-floor high located at 77°S, 16 km offshore from Cape Roberts in western McMurdo Sound, Antarctica. The recovered core is about 147 m long with the upper 43.15 metres below the sea floor (revised figure) being dated as Quarternary and the older part of the sequence being Miocene. The core includes nine facies: sandy diamict, muddy diamict, gravel/conglomerate, mud(stone), clay(stone) and carbonate. These facies occure in associations that are repeated in particulare sequences throughout the core, and are interpreted as representing different depositional environments through time. Seven lithofacies associations are interpreted as representing offshore shelf, ice protected/below wave-base; prodeltaic/offshore shelf; delta front/sandy shelf; ice system; subglacial till/rainout diamict/debris flow diamicts singly or in combination; and a carbonate-rich shelf bank. The facies associations are used to infer that the Quaternary section represents deposition on a polar shelf with perhaps two or three glacial fluctuations. The Quaternary carbonate unit indicates a period of ice sheet retreat, but local glacial activity may have increased with an increase in costal precipitation. The Miocene section represents polythermal glacial systems. The older Miocene section is glacially dominated whereas the younger section is much less so. The glacially dominated section may provide evidence for a major glacial advance thar resulted un a low stand of global eustatic sea level at that time. After the low stand, eustatic sea level was gradually rising during deposition of the younger section dominated more by non-glacial processes.

Quinols as novel therapeutic agents. 2.1 4-(1-arylsulfonylindol- 2-yl)-4-hydroxycyclohexa-2,5-dien-1-ones and related agents as potent and selective antitumor agents

A series of substituted 4-(1-arylsulfonylindol-2-yl)-4-hydroxycyclohexa-2, 5-dien-1-ones (indolylquinols) has been synthesized on the basis of the discovery of lead compound 1a and screened for antitumor activity. Synthesis of this novel series was accomplished via the "one-pot" addition of lithiated (arylsulfonyl)indoles to 4,4-dimethoxycyclohexa-2,5-dienone followed by deprotection under acidic conditions. Similar methodology gave rise to the related naphtho-, 1H-indole-, and benzimidazole-substituted quinols. A number of compounds in this new series were found to possess in vitro human tumor cell line activity substantially more potent than the recently reported antitumor 4-substituted 4-hydroxycyclohexa-2,5-dien-1-ones1 with similar patterns of selectivity against colon, renal, and breast cell lines. The most potent compound in the series in vitro, 4-(1-benzenesulfonyl-6-fluoro-1H-indol- 2-yl)-4-hydroxycyclohexa-2,5-dienone (1h), exhibits a mean GI50 value of 16 nM and a mean LC50 value of 2.24 μM in the NCI 60-cell-line screen, with LC50 activity in the HCT 116 human colon cancer cell line below 10 nM. The crystal structure of the unsubstituted indolylquinol 1a exhibits two independent molecules, both participating in intermolecular hydrogen bonds from quinol OH to carbonyl O, but one OH group also interacts intramolecularly with a sulfonyl O atom. This interaction, which strengthens upon ab initio optimization, may influence the chemical environment of the bioactive quinol moiety. In vivo, significant antitumor activity was recorded (day 28) in mice bearing subcutaneously implanted MDA-MB-435 xenografts, following intraperitoneal treatment of mice with compound 1a at 50 mg/kg.

Efeito de indutores de florescimento nas cultivares de abacaxizeiro RBR-1, SNG-2 e SNG-3 em Rio Branco-Acre.

Este trabalho teve como objetivo avaliar o efeito de indutores de florescimento em três cultivares de abacaxizeiro em Rio Branco-Acre. O delineamento experimental foi em blocos ao acaso, em esquema fatorial 3 x 2 x 2, com quatro repetições, sendo combinadas três cultivares de abacaxi (RBR-1, SNG-2 e SNG-3), dois indutores de florescimento (carbureto de cálcio-CaC2 e etefon-ácido 2-cloroetilfosfônico) e duas épocas de aplicação (aos 10 e 12 meses do plantio). As plantas induzidas com etefon aos 10 meses apresentaram maior percentagem de florescimento (96,25%) quando com CaC2 (85,42%) quando comparadas com as induzidas aos 10 meses (62,92%).
