The scarcity or complete lack of information on the adenoviruses (AdVs) occurring in the most ancient non-human primates resulted in the initiation of a study for exploring their abundance and diversity in prosimians and New World monkeys (NWMs). In order to assess the variability of these AdVs and the possible signs of the hypothesised virus−host co-evolution, samples from almost every family of NWMs and prosimians were screened for the presence of AdVs. A PCRscreening of 171 faecal or organ samples from live or dead, captive or wild-living prosimians and NWMs was performed. The PCR products from the gene of the IVa2 protein were sequenced and used in phylogeny calculations. The presence of 10 and 15 new AdVs in seven and ten different species of prosimians and NWMs was revealed, respectively. Phylogenetic analysis indicated that the tentative novel AdVs cluster into two separate groups, which form the most basal branches among the primate AdVs, and therefore support the theory on the co-evolution of primate AdVs with their hosts. This is the first report that provides a comprehensive overview of the AdVs occurring in prosimians and NWMs, and the first insight into the evolutionary relationships among AdVs from all major primate groups.

The theory of âeœcodon-amino acid coevolutionâe? was first proposed by Woese in 1967. It suggests that there is a stereochemical matching - that is, affinity - between amino acids and certain of the base triplet sequences that code for those amino acids. We have constructed a Common Periodic Table of Codons and Amino Acids, where the Nucleic Acid Table showed perfect axial symmetry for codons and the corresponding Amino Acid Table also displayedperiodicity regarding the biochemical properties (charge and hydrophobicity) of the 20 amino acids and the position of the stop signals. The Table indicates that the middle (2 nd) amino acid in the codon has a prominent role in determining some of the structural features of the amino acids. The possibility that physical contact between codons and amino acids might exist was tested on restriction enzymes. Many recognition site-like sequences were found in the coding sequences of these enzymes and as many as 73 examples of codon-amino acid co-location were observed in the 7 known 3D structures (December 2003) of endonuclease-nucleic acid complexes. These results indicate that the smallest possible units of specific nucleic acid-protein interaction are indeed the stereochemically compatible codons and amino acids.

Tanulmányunk célja, hogy bemutasson egy olyan interaktív előretekintési eljárást, amelyet egy kutatási alprojekt keretében kezdtünk el fejleszteni.Az interaktív előretekintés elképzelését az elméleti és a gyakorlati jövőkutatás kölcsönös kapcsolatát magában foglaló integrált jövőkutatás, a nyitott előretekintés és a nyitott innovációt megvalósító „élő laboratórium“ gondolatköréből merítettük. Felfogásunkban az interaktív előretekintés a különböző típusú résztvevők olyan élő hálózata, amely összekapcsolja a résztvevők közötti személyes és az on-line jövőformáló tevékenységeket. Ezt a koncepciót egy előretekintési esettanulmányban valósítottuk meg, amely a Közép-Magyarországi Régió KKV-inak lehetséges gazdasági jövőjének feltárásával foglalkozik. Az első eredmények azt mutatják, hogy a részt vevő KKV-k jövőorientáltsága közepes mértékű, a vállalkozók nem gondolják azt, hogy az innováció csodafegyver a gazdasági válság legyőzésében és az üzleti siker elérésében. Azt viszont határozottan megfogalmazzák, hogy az emberi erőforrás képzettségének üzleti szempontú kihasználása fontosabb, mint az innováció a KMR tudásgazdasága felé mutató jövők formálásában.Minthogy innovatív előretekintési eljárásunk új szociális technológiát képvisel, ezért annak eredményeit meg kell ismertetnünk elméleti és gyakorlati szakemberek széles körével. Várjuk a kritikát és a további stakeholderek részvételét az Interneten folyamatosan működő kutatási honlapunkon.

Summary  

In this paper we analyze the (historical) co-evolution of technological development and economic progress (by relating public and private R&D investment, patenting, and corporate profitability). We relate to the work ofSchmookler(1966),Griliches(1990),Pakes&Griliches(1980) andPakes(1986) who all have studied the techno-economic interplay by considering patents as in indicator of technological performance. We use United States industry and government data over the period 1953-1998 (45 years). Co-evolution analysis over this period reveals a strong interdependency among the variables. Patent evolution is strongly related to the development of private R&D and corporate profitability; the levels of public and private R&D expenditure in combination with the level of technological output (i.e. patents) have a strong predictive and explanatory power towards corporate profitability (R2 value of 94.9%). Causality tests reveal a joint determination between R&D investment and corporate profitability (L=2; p<0.01).

This paper describes a hypothesis on the origin of the members of the recently established adenovirus genus, Atadenovirus, invading cattle, sheep, deer, duck and poultry. Comparison of the phylogenetic trees of adenoviruses and their hosts suggests a very ancient but common origin for the atadenoviruses. The surprisingly large difference between these virus types and other adenoviruses infecting the same host can be easily understood by assuming their separate evolution in different hosts (e.g., in reptiles versus a coevolution with mammals and birds, respectively) followed by a later host switch.
