    Notes: Secondary ion mass spectrometry (SIMS) has been used to generate images of polymeric materials including a polymer laminate and metal-chelated organic materials cured on Teflon substrates. Metal-chelation facilitated the imaging of organic materials by monitoring of the metallic tag. Incorporation of the metal into the organic complex made the sample conductive therefore circumventing charging difficulties normally associated with SIMS analysis of organics. Each layer of the polymer laminate could be easily identified by monitoring molecular fragment ions that were distinctive for each polymer type. Images were acquired at a resolution of approximately 5-10 μm.

    Description: A sensitive radioimmunoassay for atrial natriuretic peptide was used to examine the relation between circulating atrial natriuretic peptide and cardiac filling pressure in normal human subjects, in patients with cardiovascular disease and normal cardiac filling pressure, and in patients with cardiovascular disease and elevated cardiac filling pressure with and without congestive heart failure. The present studies establish a normal range for atrial natriuretic peptide in normal human subjects. These studies also establish that elevated cardiac filling pressure is associated with increased circulating concentrations of atrial natriuretic peptide and that congestive heart failure is not characterized by a deficiency in atrial natriuretic peptide, but with its elevation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Burnett, J C Jr -- Kao, P C -- Hu, D C -- Heser, D W -- Heublein, D -- Granger, J P -- Opgenorth, T J -- Reeder, G S -- New York, N.Y. -- Science. 1986 Mar 7;231(4742):1145-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2935937" target="_blank"〉PubMed〈/a〉

    Description: Cachectin (tumor necrosis factor), a protein produced in large quantities by endotoxin-activated macrophages, has been implicated as an important mediator of the lethal effect of endotoxin. Recombinant human cachectin was infused into rats in an effort to determine whether cachectin, by itself, can elicit the derangements of host physiology caused by administration of endotoxin. When administered in quantities similar to those produced endogenously in response to endotoxin, cachectin causes hypotension, metabolic acidosis, hemoconcentration, and death within minutes to hours, as a result of respiratory arrest. Hyperglycemia and hyperkalemia were also observed after infusion. At necropsy, diffuse pulmonary inflammation and hemorrhage were apparent on gross and histopathologic examination, along with ischemic and hemorrhagic lesions of the gastrointestinal tract, and acute renal tubular necrosis. Thus, it appears that a single protein mediator (cachectin) is capable of inducing many of the deleterious effects of endotoxin.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tracey, K J -- Beutler, B -- Lowry, S F -- Merryweather, J -- Wolpe, S -- Milsark, I W -- Hariri, R J -- Fahey, T J 3rd -- Zentella, A -- Albert, J D -- New York, N.Y. -- Science. 1986 Oct 24;234(4775):470-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3764421" target="_blank"〉PubMed〈/a〉

    Notes: The CD and absorption (OD) spectra of single-stranded nucleic acids in complex with the helix-destabilizing protein of either bacteriophage T4 (GP32) or bacteriophage fd (GP5) show similar and unusual features for all polynucleotides investigated. The change in the CD spectra between 310 and 240 nm is in all cases characterized by a considerable decrease in the positive band, while the negative band (if present) remains relatively intense. These changes are different from those due to temperature or solvent denaturation and, moreover, cannot be induced by the binding of simple oligopeptides. Absorption measurements show that all polynucleotides remain hypochromic in the complex. Both CD and OD spectra point to a specific and probably similar conformation in complex for all polynucleotides with substantial interactions between the bases. The spectral properties are almost temperature independent (0-40°C). Therefore, we conclude that the conformation must be regular and rigid. To investigate the relation between these optical properties and the specific polynucleotide structure, CD and OD spectra were calculated for an adenine hexamer over a wide range of the conformational parameters. It appears that the calculated CD intensity is not very sensitive to an increase in the axial increment and that many different conformations can give rise to more or less similar CD spectra. However, simulation of the very nonconservative experimental CD spectrum of the poly(rA)-GP32 complex requires that the conformation satisfies two criteria: (1) a considerable tilt of the bases (≲ - 10°) in combination with (2) a small rotation per base (≃20°) and/or a position of the bases close to the helix axis (dx ≃ 0 Å). Such conformations can also explain the observed hyperchromism upon binding of GP32 to poly(rA)/(dA). Very similar structural characteristics also account for the optical properties of the complexes with GP5. These are discussed as an alternative to the structure suggested by Alma-Zeestraten for poly(dA) in the complex [N. C. M. Alma-Zeestraten (1982) Doctoral thesis Catholic University, Nijmegen, The Netherlands]. The secondary structure proposed in this work can be reconciled with the overall dimensions of the complex, assuming that the polynucleotide helix is further organized in a superhelix.
