Neopaleozoic striated surfaces in the granitic basement and clast pavement remains of Salto, SP

Near Guarau Ceramic, localized southwest of Salto city in the State of Sao Paulo, two granite outcrops, distant some tens of meters from each other, display Neopaleozoic striated surfaces. These surfaces are in contact with diamictites from the Itarare Subgroup. The striae correspond to sub parallel grooves with millimetric spacing and depth, oriented about N48E and dipping 12 degrees to 42 degrees towards SE. Observed features and association with diamictites indicate an origin by glacial abrasion due to ice movement from southeast towards northwest. About 1.8 km east of Salto, unconsolidated material containing flat-iron-shaped and striated clasts was found on top of granite outcrops, interpreted as clasts pavement remains.

Cearania heterophylla gen. nov et sp nov., a fossil gymnosperm with affinities to the Gnetales from the Early Cretaceous of northern Gondwana

Vegetative and fertile shoots of a shrub-like seed plant from the late Aptian Crato Formation of Brazil are described as Cearania heterophylla Kunzmann, Mohr and Bernardes-de-Oliveira, gen. nov. et sp. nov. Anatomical details of the axes, epidermal features and separate ovulate and pollen producing organs indicate the gymnospermous nature of this plant. The vascular tissue of the axes includes tracheids with bordered pits and fiber tracheids. Vegetative shoots comprising at least three branching orders bear opposite-decussately arranged ovate to lanceolate, dorsiventrally flattened, parallelodromous, rather thick leaves that vary tremendously in size. The amphistomatic leaves bear (brachy-)paracytic stomatal complexes arranged in simple longitudinal files. The ovulate structure is interpreted as a terminally attached single globular ovule/seed surrounded by at least five to six lanceolate bracts. A terminally attached pollen-cone like structure grows on a lateral leafy shoot. The unusual character combination may indicate that the fossils belong to a hitherto unknown group with affinities to ephedroid Gnetales. Sterile shoots formerly often described as Podozamites, Nageiopsis or Lilites that are at least partly congeneric with C. heterophylla Kunzmann, Mohr and Bernardes-de-Oliveira, gen. nov. et sp. nov. had a wide geographic distribution during the Early Cretaceous.

Structure and Calcium-Binding Activity of LipL32, the Major Surface Antigen of Pathogenic Leptospira sp.

Leptospixosis, a spirochaetal zoonotic disease caused by Leptospira, has been recognized as an important emerging infectious disease. LipL32 is the major exposed outer membrane protein found exclusively in pathogenic leptospires, where it accounts for up to 75% of the total outer membrane proteins. It is highly immunogenic, and recent studies have implicated LipL32 as an extracellular matrix binding protein, interacting with collagens, fibronectin, and laminin. In order to better understand the biological role and the structural requirements for the function of this important lipoprotein, we have determined the 2.25-angstrom-resolution structure of recombinant LipL32 protein corresponding to residues 21-272 of the wild-type protein (LipL32(21-272)). The LipL32(21-272) monomer is made of a jelly-roll fold core from which several peripheral secondary structures protrude. LipL32(21-272) is structurally similar to several other jelly-roll proteins, some of which bind calcium ions and extracellular matrix proteins. Indeed, spectroscopic data (circular dichroism, intrinsic tryptophan fluorescence, and extrinsic 1-amino-2-naphthol-4-sulfonic acid fluorescence) confirmed the calcium-binding properties of LipL32(21-272). Ca(2+) binding resulted in a significant increase in the thermal stability of the protein, and binding was specific for Ca(2+) as no structural or stability perturbations were observed for Mg(2+), Zn(2+), or Cu(2+). Careful examination of the crystal lographic structure suggests the locations of putative regions that could mediate Ca(2+) binding as well as binding to other interacting host proteins, such as collagens, fibronectin, and lamixidn.

Sesquiterpenes from Xylaria sp., an endophytic fungus associated with Piper aduncum (Piperaceae)

Two new presilphiperfolane sesquiterpenes, 1 and 2, were isolated from the ethyl acetate extract of Xylaria sp., obtained from the leaves of Piper aduncum, along with two known eremophilane sesquiterpenes, phaseolinone (3) and phomenone (4). Chemical structures of 1 and 2 were established by analysis of spectroscopic data. The four compounds were tested in vitro for antifungal and cytotoxicity activities using CHO (Chinese hamster ovary). Compounds 1 and 2 did not show any antifungal and cytotoxic activity. Compounds 3 and 4 displayed moderate cytotoxic activities, as well as 4 antifungal activity. (C) 2010 Phytochemical Society of Europe. Published by Elsevier B. V. All rights reserved.

Valet f��r livet? : En kvantitativ unders��kning om hur elever p�� SP- programmet motiverar sitt gymnasieval och hur skolornas marknadsf��ring ser ut.

Syftet med uppsatsen var att unders��ka vilka faktorer som p��verkar samh��llsprogrammets elevers val av skola. F��r att unders��ka detta genomf��rdes en enk��tunders��kning p�� tre gymnasieskolor och skolornas respektive marknadsf��ring unders��ktes. Unders��kningen visade att samh��llsprogramseleverna i sitt skolval framf��rallt p��verkats mest av skolornas ��ppna hus samt at skolorna hade rykte om att ha bra l��rare, valbara kurser, skolmat och allm��n st��mning p�� skolan. Dessutom spelar skolans geografiska l��ge en roll. Vi kom fram till att de flesta eleverna vill att skolan ligger n��ra t��g och buss och ganska centralt. I den kommunala skolan var n��rheten till hemmet avg��rande. Eleverna anser sj��lva att f��r��ldrarna och kompisarnas p��verkan inte ��r avg��rande f��r deras gymnasieval. Dessutom kom vi fram till att den st��rre delen av eleverna hade h��gutbildade f��r��ldrar och de flesta hade en svensk bakgrund. P�� den kommunala skolan, som l��g p�� landsbygden, var andelen elever med utl��ndska f��r��ldrar st��rst. V��rt resultat st��mmer ��verrens med tidigare forskning, d�� det redan tidigare har kommit fram till att elever med utl��ndsk bakgrund oftast g��r till skolor som ligger i f��rorter fr��n st��rre st��der. Dessutom ��r andelen elever med utl��ndska f��r��ldrar mycket mindre p�� frist��ende skolor ��n p�� kommunala skolor. I tidigare forskning har ytterligare kommit fram att h��gutbildade f��r��ldrar g��r ett mer medvetet och aktivt val n��r de v��ljer gymnasium och att fler h��gutbildade f��r��ldrar v��ljer en frist��ende skola, ��n l��gutbildade f��r��ldrar. P�� de skolors SP-programelever vi unders��kte s��g vi att den st��rsta delen av f��r��ldrarna var h��gutbildade och att en stor grupp var l��rare. SP-programmet ��r studief��rberedande och d��rf��r kan det vara s�� att eleverna p��verkats av f��r��ldrarnas socioekonomiska status i sitt val, vilket skulle st��mma ��verens med tidigare forskning, ��ven om de sj��lva ser det som ett fritt och sj��lvst��ndigt val.

The Physiological, Enzymatic, and Genetic Characterization of Staphylococcus sp. Chromium (VI) Reductase Function

A strain of Staphylococcus isolated by Dr. Fekete at the Sandia National Laboratory toxic metal dumping site in Sandia, New Mexico. has been found to reduce toxic Cr(VI) to the less toxic Cr(IlI) state. We have ascertained the environmental parameters for optimal bacterial growth and Cr(VI) reduction. This knowledge may be employed in a comprehensive bioremediation scheme designed to accelerate natural reparation of that Sandia ecosystem. In addition we have investigated the genetic and enzymatic basis for this Cr(VI) reducing ability. This information may allow us to create more effective bioremediation schemes based on the comprehensive knowledge of enzyme and gene function. Preliminary investigations have been carried out toward this end which may serve as the basis for a more thorough investigation.

Compara����o dos principais constituintes qu��micos de duas esp��cies de arnica: Cravorana (Porophyllum Ruderale [Jacq.] Cass) e Var��o-de-Ouro (Solidago SP.)
