13. Termoquimica dos adultos entre trifenilfosfinoxido e cloretos de zinco
The standard enthalpy change (DRH) for the reaction: MCl2 (s) + 2TPPO (s) = MCl2 . 2TPPO (s); DRH (M = Zn, Cd and Hg (II), TPPO = triphenylphosphineoxide), was measured by using solution calorimetry. The standard enthalpy change due to the sublimation of TPPO (DsH). Was also measured. By using these data together with others found in the literature, it was p

14. Characterization of a DEAD box ATPase/RNA helicase protein of Arabidopsis thaliana.
We have isolated cDNAs encoding a novel member of the DEAD box RNA helicase family from Arabidopsis. The protein, named AtDRH1, is composed of 619 amino acids and the central portion has high similarity with the helicase core region of a prototypic RNA helicase, the human nuclear protein p68. The N- and C-terminal regions are considerably diverged from the a

15. Structural Characterization of the Released Polysaccharide of Desiccation-Tolerant Nostoc commune DRH-1
The structure of the viscous extracellular polysaccharide (glycan) of desiccation-tolerant Nostoc commune DRH-1 was determined through chromatographic and spectroscopic methods. The polysaccharide is novel in that it possesses a 1-4-linked xylogalactoglucan backbone with d-ribofuranose and 3-O-[(R)-1-carboxyethyl]-d-glucuronic acid (nosturonic acid) pendant

16. Clinical evaluation of teicoplanin fluorescence polarization immunoassay.
A teicoplanin fluorescence polarization immunoassay (FPIA) developed by International BioClinical (IBC) was evaluated by using serum samples from patients who had been receiving teicoplanin at Detroit Receiving Hospital (DRH) as part of a clinical investigation. Patient samples collected over a 1-year span were assayed at DRH and at IBC, and the results were

17. cDNA clones coding for the heavy chain of human HLA-DR antigen.
Two cDNA clones, pDRH1 and pDRH2, containing sequences specific for human HLA-DR antigens were isolated from a bank of cDNA clones made from partially purified HLA-DR mRNA from the human lymphoblastoid cell line Maja. The clones were specific for the Mr 34,000 HLA-DR antigen glycoprotein chain. The identity of these clones was established by (i) their abilit

18. Active Fe-Containing Superoxide Dismutase and Abundant sodF mRNA in Nostoc commune (Cyanobacteria) after Years of Desiccation
Active Fe-superoxide dismutase (SodF) was the third most abundant soluble protein in cells of Nostoc commune CHEN/1986 after prolonged (13 years) storage in the desiccated state. Upon rehydration, Fe-containing superoxide disumutase (Fe-SOD) was released and the activity was distributed between rehydrating cells and the extracellular fluid. The 21-kDa Fe-SOD

19. Solubilization of adenosine triphosphatase from membranes of Escherichia coli: effect of p-aminobenzamidine.
The five subunits of the membrane-bound adenosine triphosphatase (F1) from Escherichia coli were identified on electrophoretograms of membranes which had been washed with a low-ionic-strength buffer containing the protease inhibitor p-aminobenzamidine. All of the subunits of the membrane-bound F1 appeared to have the same molecular weights and isoelectric po

20. cDNA clones for the heavy chain of HLA-DR antigens obtained after immunopurification of polysomes by monoclonal antibody.
A monoclonal antibody (HC 2.1) directed against the separated heavy chain of HLA-DR has been prepared. By binding HC 2.1 to polysomes from human B lymphoblastoid cells followed by the use of a protein A-Sepharose column as an immunoadsorbent, we have purified the mRNA coding for the HLA-DR heavy chain nearly to homogeneity. The immunopurified mRNA has been u

21. Mutations in the Saccharomyces Cerevisiae Type 2a Protein Phosphatase Catalytic Subunit Reveal Roles in Cell Wall Integrity, Actin Cytoskeleton Organization and Mitosis
Temperature-sensitive mutations were generated in the Saccharomyces cerevisiae PPH22 gene that, together with its homologue PPH21, encode the catalytic subunit of type 2A protein phosphatase (PP2A). At the restrictive temperature (37°), cells dependent solely on pph22(ts) alleles for PP2A function displayed a rapid arrest of proliferation. Ts(-) pph22 mutan
