    Description: Genetic variations may change the structure and function of individual proteins as well as affect their interactions with other proteins and thereby impact metabolic processes dependent on protein-protein interactions. For example, cytochrome P450 proteins, which metabolize a vast array of drugs, steroids and other xenobiotics, are dependent on interactions with redox and allosteric partner proteins for their localization, stability, (catalytic) function and metabolic diversity (reactions). Genetic variations may impact such interactions by changing the splicing and/or amino acid sequence which in turn may impact protein topology, localization, post translational modifications and three dimensional structure. More generally, research on single gene defects and their role in disease, as well as recent large scale sequencing studies suggest that a large number of genetic variations may contribute to disease not only by affecting gene function or expression but also by modulating complex protein interaction networks. The aim of this research topic is to bring together researchers working in the area of drug, steroid and xenobiotic metabolism who are studying protein-protein interactions, to describe their recent advances in the field. We are aiming for a comprehensive analysis of the subject from different approaches including genetics, proteomics, transcriptomics, structural biology, biochemistry and pharmacology. Of particular interest are papers dealing with translational research describing the role of novel genetic variations altering protein-protein interaction. Authors may submit original articles, reviews and opinion or hypothesis papers dealing with the role of protein-protein interactions in health and disease. Potential topics include, but are not limited to: • Role of protein-protein interactions in xenobiotic metabolism by cytochrome P450s and other drug metabolism enzymes. • Role of classical and novel interaction partners for cytochrome P450-dependent metabolism which may include interactions with redox partners, interactions with other P450 enzymes to form P450 dimers/multimers, P450-UGT interactions and proteins involved in posttranslational modification of P450s. • Effect of genetic variations (mutations and polymorphisms) on metabolism affected by protein-protein interactions. • Structural implications of mutations and polymorphisms on protein-protein interactions. • Functional characterization of protein-protein interactions. • Analysis of protein-protein interaction networks in health and disease. • Regulatory mechanisms governing metabolic processes based on protein-protein interactions. • Experimental approaches for identification of new protein-protein interactions including changes caused by mutations and polymorphisms.

    Description: Diese Arbeit hat sich die Aufgabe gestellt, dem nachzugehen, was es mit der Trägheit eines Oblomov oder der Langeweile eines Rajskij auf sich hat und verwendet dafür die Bildlichkeit, um erneut einen Zugang zu dem Denken Gončarovs zu finden. Schon die Titel der drei Romane stecken das Arbeitsfeld ab. Der Titel "Obyknovennaja Istorija", Eine gewöhnliche Geschichte, zeigt, daß wir es mit alltäglichen Lebenserscheinungen zu tun haben, der Name "Oblomov" weist als sprechender Name auf die Zerstörung der Identität von der Person Oblomov und der Landschaft Oblomovka hin, der dritte Roman "Obryv" stellt das Symbol des Abgrunds in den Mittelpunkt des letzten Romans.

    Notes: Gettering is already an integral part of fabricating integrated circuits using Si substrates. It is anticipated that this will also be true for solar cell fabrication in the near future. A readily available technique compatible with solar cell processing is gettering by the Si wafer back surface Al. Recently, available solar cell efficiency studies have shown the beneficial effects of the wafer backside Al, including that of gettering, a wafer backside field, and grain boundary and dislocation passivation. In this article, we report on experimental results which showed that Czochralski Si wafer bulk minority carrier diffusion lengths can be substantially improved by wafer backside Al treatment, which also provided an effect of protection from environmental contamination. In these experiments, only the effect of gettering is present and therefore the results constitute an unambiguous demonstration of the benefits of gettering by Al. © 1995 American Institute of Physics.

    Notes: Expressions of the thermal equilibrium concentrations of Si in GaAs have been obtained in terms of fundamental constants of the involved materials. Silicon is an amphoteric dopant in GaAs, with four species: a neutral and an ionized shallow donor species occupying Ga sublattice sites, and a neutral and an ionized shallow acceptor species occupying As sublattice sites. The concentration of an ionized Si species is expressed by the concentration of the appropriate neutral species and the GaAs crystal Fermi level or the carrier concentration and the band gap energy level positions. The thermal equilibrium concentrations of the two neutral species are expressed by the relevant Gibbs free energies of formation and the As4 vapor phase pressure in the ambient. Using these equations, the long observed relations between the carrier and Si concentrations in different experiments involving both n- and p-type Si doping produced GaAs are quantitatively explained. A difference of ∼1.55 eV in the effective formation enthalpy between the neutral Si atoms occupying the As and Ga sublattice sites has been identified. Moreover, at high temperatures, the GaAs intrinsic Fermi level energy Ei appears to be higher than the midgap energy Eg/2 by ∼20–80 meV. © 1999 American Institute of Physics.

    Notes: We propose a quantitative model for Si diffusion in GaAs. In this model we incorporate the experimental result that Si is an amphoteric impurity which constitutes a shallow donor when occupying the Ga site, Si+Ga, and a shallow acceptor when occupying the As site, Si−As. At high concentrations Si+Ga and Si−As coexist. The amphoteric behavior of Si may be viewed as an effect of the Fermi level. We assume that Si+Ga and Si−As diffuse respectively on the Ga and As sublattices. That is, the diffusion of Si+Ga and Si−As is governed by the variously charged Ga vacancies and As vacancies (or self-interstitials), respectively. The experimentally observed Si diffusivity is concentration dependent which results from the Si amphoteric nature as well as from another effect of the Fermi level, which is its influence on the concentrations of the charged point-defect species. Satisfactory quantitative descriptions of available experimental results are obtained. An analysis of the data on Si diffusion into a Sn-doped GaAs substrate has led us to believe that the previously proposed Si-pair diffusion model may no longer be favored.

    Notes: The retardation phenomenon of oxygen precipitation in Czochralski silicon has been studied simultaneously with the growth of surface stacking faults under a silicon nitride capping layer. The surface faults were intentionally introduced to monitor the bulk self-interstitial supersaturation in the crystal during precipitate growth. It was observed that an increase in the low-temperature nucleation anneal time resulted in a reduced rate of oxygen precipitation and an enhanced rate of surface stacking fault growth at high temperatures. This indicates that as the nucleation anneal time increases, silicon self-interstitials, which must be generated for precipitation to proceed, reach a high level of supersaturation and cause the annihilation of most nuclei generated during the nucleation anneal.
