Published 2001Staff ViewISSN: 1089-7674Source: AIP Digital ArchiveTopics: PhysicsNotes: The role of energetic electrons in periodic self-oscillations of a discharge plasma has been studied by measuring the spatiotemporal evolution of plasma potential, electron density, and electron velocity distribution function. It is found that the self-oscillation involves the instabilities of sheaths, propagation of a double layer and competition between the ionization, thermalization, and diffusion. The energetic electrons are the key factor which links these processes to form the oscillation cycle. The time interval of each phase in the cycle is estimated according to the physical process and the calculations are in agreement with experimental measurements. The study of the probe perturbation effect on the oscillations indicates that the length of the oscillation period is related to the amount of energetic electrons; the more energetic electrons, the shorter the period. © 2001 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 2003Staff ViewISSN: 1471-4159Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Opioid peptides exert their regulatory effects on both central and pheripheral nervous systems via multiple opioid receptors that are linked to seemingly identical sets of guanine nucleotide-binding regulatory proteins (G proteins). In contrast to the μ-opioid receptor, the δ-opioid receptor can efficiently stimulate phospholipase C via G16. We used a series of μ/δ-opioid receptor chimeras to examine the involvement of intracellular receptor domains in the recognition of G16. After ascertaining that the chimeras can bind opioid ligands with high affinity and elicit inhibition of adenylyl cyclase, COS-7 cells were cotransfected with cDNAs encoding Gα16 and a μ/δ-opioid receptor chimera and assayed for [d-Ala2,d-Leu5]enkephalin-induced stimulation of phospholipase C. Our results indicate that (i) the carboxy terminal tail of the δ-opioid receptor is necessary but insufficient for conferring coupling to Gα16, (ii) the third inner loop together with the carboxy terminal tail of the δ-opioid receptor can provide sufficient contact domains for Gα16, and (iii) the first inner loop of the δ-opioid receptor, in particular Leu80, as well as the fifth transmembrane domain and/or the third extracellular loop may also contribute in defining the fidelity of interaction between the δ-opioid receptor and Gα16. These results indicate that efficient coupling of the δ-opioid receptor to Gα16 requires the participation of most of the intracellular regions, including the first intracellular loop.Type of Medium: Electronic ResourceURL: -

ISSN: 1430-4171Source: Springer Online Journal Archives 1860-2000Topics: Chemistry and PharmacologyNotes: Abstract This article describes an on-campus celebration program for National Chemistry Week (NCW) at the University of Pittsburgh at Titusville (UPT). The program, consisting of a chemistry magic show, hands-on chemistry fun, and a poster display session, was presented free of charge to the public on the Saturday of NCW. Presenting the program on campus avoided the transportation of the necessary materials, allowed the incorporation of many interesting demonstrations, and provided an opportunity for the school to showcase its state-of-the-art facilities. The program reached the public through different media, such as flyers, newspapes, and TV and radio. Over 100 people of all ages from the local community participated in the program. One of the most successful characteristics of the program was the substantial involvement of college students taking chemistry classes. Directly doing or seeing various reactions that involved changes in color or production of sound, heat, or light was stimulating and memorable. Many student participants became chemistry club members right after the events and were excited about more opportunities to explore the world of chemistry. This article also described activities highlighting the theme of NCW 1999, “Celebrating Polymers.”Type of Medium: Electronic ResourceURL: -

ISSN: 0006-3592Keywords: protein purification ; peptide libraries ; ligands ; Chemistry ; Biochemistry and BiotechnologySource: Wiley InterScience Backfile Collection 1832-2000Topics: BiologyProcess Engineering, Biotechnology, Nutrition TechnologyNotes: Peptide libraries can be used to identify ligands that bind specifically to a desired protein. These peptides may have significant advantages as specific ligands for affinity chromatography separations. This article describes the use of one of such peptide, Try-Asn-Phe-Glu-Val-Leu, as a ligand for the purification of S-protein using affinity chromatography. General strategies for peptide immobilization are discussed and the conditions for peptide immobilization to Emphaze™ gel are optimized. The effects of peptide orientation and peptide densities on protein binding are studied. Results indicate that the peptide affinity is not affected by the orientation of the peptide during immobilization, but association constants can be reduced by one order of magnitude when compared with the values in solution.With increased peptide density, the protein binding capacity of the gel increases, but both the percentage of peptide utilization and apparent binding constant between immobilized peptide and S-protein decrease. S-protein is separated from a mixture with BSA via affinity chromatography using specific elution with the peptide in solution.Finally, direct purification of S-protein from an enzymatic digestion mixture of ribonuclease A is demonstrated.© 1995 John Wiley & Sons, IncAdditional Material: 9 Ill.Type of Medium: Electronic ResourceURL:
