Method for cloning and producing the TfiI
Restriction endonuclease in Escherichia coli
A genomic DNA library of Thermus filiformis was con-structed using pBR322 as a cloning vector. The methylaseselection method was used to clone the TfiI methylase gene(tfiIM). A clone carrying an active TfiI methylase wasidentified. After sequencing the complete TfiI methylase geneand its downstream DNA sequence, a recombinase homologwas found. Because the methylase and its cognate endonu-clease gene are located in proximity to each other in aparticular restriction–modification system, efforts weremadeto clone the upstreamDNA by inverse PCR. After two roundsof inverse PCR, one open reading frame (ORF1) was foundupstream of the TfiI methylase gene. This ORF1, containing aShine-Dalgarno sequence and a TATA box on the upstreamside, was cloned and expressed, and TfiI endonuclease activ-ity was detected in crude cell extracts. It is concluded thatORF1 encodes TfiI restriction endonuclease.

promoter (e.g, a promoter composed of a minimal promoterlinked to multiple copies of tetO, the binding site for thetetracycline repressor (tetR) of the Escherichia coli tetracy-cline resistance operon Tn10). Expression from the induci-ble promoter is regulated by a multichimeric transactivatingfactor, composed of a first ligand-binding domain thatnegatively regulates transcription (e.g., a prokaryotic tetra-cycline repressor polypeptide), a transcriptional activationdomain, and a second ligand-binding domain that positivelyregulates the transcriptional activation function of the trans-activator [e.g., a ligand-binding domain of a steroid receptor,preferably an estrogen receptor (ER)]. Transcription of thenucleotide sequence under control of the inducible promoteris activated by the multichimeric transactivator when boththe ligand that binds the first ligand-binding domain (e.g.,tetracycline) is absent and the ligand that binds the secondligand-binding domain (e.g., a steroid) is present. Thisinducible expression system is particularly useful in theexpression of the cytotoxic protein VSV G for the produc-tion of pseudotyped retroviral vectors.

Unimolecular segment amplification
and sequencing
Disclosed are compositions and a method for amplificationof and multiplex detection of molecules of interest involvingrolling circle replication. The method is useful for simulta-neously detecting multiple specific nucleic acids in a samplewith high specificity and sensitivity. The method also has aninherently low level of background signal. A preferred formof the method consists of an association operation, anamplification operation, and a detection operation. Theassociation operation involves association of one or morespecially designed probe molecules, either wholly or partlynucleic acid, to target molecules of interest. This operationassociates the probe molecules to target molecules present ina sample. The amplification operation is rolling circlereplication of circular nucleic acid molecules, termed ampli-fication target circles that are either a part of, or hybridizedto, the probe molecules. A single round of amplificationusing rolling circle replication results in a large amplificationof the amplification target circles. Following rolling circlereplication, the amplified sequences are detected usingcombinatorial multicolor coding probes that allow separate,simultaneous, and quantitative detection of multiple differ-ent amplified target circles representing multiple differenttarget molecules. Since the amplified product is directlyproportional to the amount of target sequence present in asample, quantitative measurements reliably represent theamount of a target sequence in a sample. Major advantagesof this method are that a large number of distinct targetmolecules can be detected simultaneously, and that differ-ences in the amounts of the various target molecules in asample can be accurately quantified. It is also advantageousthat the DNA replication step is isothermal, and that signalsare strictly quantitative because the amplification reaction islinear and is catalyzed by a highly processive enzyme.

Methods to assay a thrombopoietin signaling
defect in polycythemia vera platelets
Impaired TPO-mediated platelet protein tyrosine phosphor-ylation was consistently observed in patients with poly-cythemia vera (PV) as well as those with idiopathicmyelofibrosis (IMF), in contrast to patients with essentialthrombocytosis, chronic myelogenous leukemia, secondaryerythrocytosis, iron deficiency anemia, hemochromatosisor normal volunteers. Moreover, the platelet TPO receptor,Mpl, was not detectable by immunoblotting with an anti-body to the extracellular domain, by chemical crosslinkingof TPO to the surface of platelets, or by flow cytometryusing an antibody to the extracellular domain, in 34 of 34PV patients and also in 13 of 14 IMF patients. ImpairedTPO-induced protein tyrosine phosphorylation in PV andIMF platelets was uniformly associated with markedlyreduced or absent expression of the extracellular domainof Mpl. Thus, the reduced detectablility of Mpl by these
methods can be used a marker of PV and IMF. Theabnormality appears to distinguish PV from other forms oferythrocytosis and may be involved in the platelet functiondefect associated with PV.

In a spark plug, the resistor composition constituting aresistor contains semiconductive ceramic particles, offeringa superior load life characteristic. Also, the value of(a2�a1)/a1�� 0.30, where a value of electric resistancebetween a terminal and a center electrode is a1 at 20�C anda2 at 150�C, so that deterioration of the radio frequency noiseprevention performance at high temperatures can be effec-tively suppressed. The resistor composition contains semi-conductive ceramic particles whose temperature coefficientof electric resistance shows a positive value, or a negativevalue of relatively small absolute value, (e.g., TiO2 particleshaving a rutile type crystalline structure, titanate or zirconateof alkali earth metal elements, titanium suboxide, etc.), ortitanium metal. Thus, the invention provides a resistor-incorporated spark plug, which is enabled to offer a stableload life characteristic even when a high load acts thereon,and which is unlikely to deteriorate in the radio frequencynoise prevention performance even under high temperatures.

Methods for enhancing the production of
interferon in cell culture
Methods for enhancing the production of interferons inanimal cell culture are described. These methods rely onthe manipulation of the cellular levels of certain inducers ofinterferon production, in particular, cellular levels of double-stranded RNA-dependent kinase (dsRNA-PKR, or PKR). Incell cultures that overproduce PKR, interferon synthesis isinduced to high levels, and significant amounts of interferoncan be recovered without conventional induction of inter-feron by virus.

The coding information for three putative chicken anemiavirus proteins (VP1, VP2, VP3) was inserted into abaculovirus vector and expressed in insect cells. Theimmunogenic properties of the chicken anemia virus(CAV) proteins produced separately or together ininsect-cell cultures were analyzed by inoculating theminto chickens. Only lysates of insect cells which havesynthesized equivalent amounts of all three recombinantCAV proteins or cells which synthesized mainly VP1 plusVP2 induced neutralizing antibodies directed against CAVin inoculated chickens. Progeny of those chickens wereprotected against clinical disease after CAV challenge.Inoculation of a mixture of lysates of cells that wereseparately infected with VP1-, VP2- and VP3-recombinantbaculovirus did not induce significant levels of neutraliz-ing antibody directed against CAV and their progeny werenot protected against CAV challenge. Our results indicatethat expression in the same cell of at least two CAVproteins, VP1 plus VP2, is required to obtain sufficientprotection in chickens. Therefore, recombinant CAV pro-teins produced by baculovirus vectors can be used as asubunit vaccine against CAV infections.

Method for the production of anti-Escherichia coli
O157:H7 antibody
Disclosed is a method for producing anti-Escherichia coliO157 antibodies. Anti-E. coli O157:H7 antibodies are pro-duced in egg-laying hens and isolated from the eggs. E. coliO157:H7 is cultured in a brain–heart infusion broth and killedby the treatment with hot water for 5–10 min. After beingcollected by centrifugation, the dead bacteria are homogen-ized. Serving as an antigenic material, the bacterial homoge-nate is injected into egg-laying hens to induce antibodiesagainst E. coli O157:H7 in the eggs. The induced antibodiesare isolated from the yolk of the eggs and the eggs containingthe antibodies against E. coliO157:H7 can be utilized, in theirentirety, for foods. Alternatively, the yolks are separated fromthe eggs and freeze-dried. The resulting dried egg componentcanbeapplied toprocessed foodstuffs, aloneor in combinationwithwhole eggs. Since the antibodies againstE. coliO157:H7are contained in frozen eggs, it is very convenient to store theantibodies. The storage in the frozen eggs also makes itpossible to apply the antibodies to almost all foods at any time.

Process using ammonia-rich water for the
selection and enrichment of nitrifying
micro-organisms for nitrification
of wastewater
The present invention comprises a method for biologicaloxidation of nitrogen in water, e.g., wastewater, nitrification,by using ammonia-rich water for the selection and enrichmentof nitrifying micro-organisms in a separate aerated reactionvolume, where organic matter already has been reduced. Thenitrifying micro-organisms will get a competing edge com-pared to other species, as they are being able to obtain energyfrom the oxidation of ammonia into nitrate. Themethod can beapplied to the activated sludge process by the introduction of asludge aeration zone on the recycled sludge, and also be
combined with a sludge anoxic zone, for denitrification,enabling a more reliable operation of biological nitrogen aswell as phosphorus removal, by maximal use of reactionvolumes with lower detention time and lower costs. It canalso be applied to a fixed bed process. The possibility ofstimulating the micro-organisms to higher activity by chang-ing the physical–chemical conditions is also included, as wellas improving the sludge separation characteristics. Themethod is enabling an overall view of the process, integratingdifferent process stages for optimisation and best possibleoperational results.
