“TOTALS”: Transfer of technology approached logically and systematically

Most efforts in transferring technology to a specific location are carried out following essentially a research approach. However, imposing the research approach onto a situation for which a specific solution needs to be created or restructured represents an inappropriate transfer of technology. A planning and design approach (PDA) is called for. “TOTALS” is based on planning and design concepts adapted to solving the problems of technology transfer. It is composed of six time-based and repeating phases, comprised of nineteen steps. It is based on four important concepts: a systems view of technology, a Technology Transfer Equation, five different purposeful perspectives regarding technology transfer activities, and a holistic PDA. No particular approach, technique, model or body of knowledge can be said to be predominant.     

The Language of Practical Philosophy

Kant's criticism is based on the idea that all possible knowledge of facts is determined by the immanent structure of our apparatus of cognition, and that therefore we have no access to reality as it is per se (" Ding an sich "). In modern analytical philosophy some elements of this view survived, namely, the distinction between framework construction and actual data of experience, supposition or voluntary setting. The conditio humana is characterised by our capacity of acting. Acting is defined as behaviour determined and controlled by information processes. The structure of these processes defines the semantics and logical principles of practical philosophy. From this view follows the conception of value judgments, the logic of preferences, formal teleology, the analysis of utility and norm logic. The framework theories should be open in order to be able to express all possible theoretical views, namely, subjectivism as well as objectivism. The paper gives a concise account of the systems of practical thought (formal axiology, formal teleology, preference logic and norm logic) and their gnoseological problems.     

Highly sensitive HLA-DNA typing from formalin-fixed and paraffin-embedded tissue samples

Nucleotide sequences have been determined for more than 1700 different alleles at the core of the human leukocyte antigen (HLA) system. The highly polymorphic character of these genes affects adaptive immune response and is also useful for forensic applications. HLA typing from formalin-fixed and paraffin-embedded tissue provides abundant useful information for both clinical settings and forensic investigations. This study, which investigated the potential use of DNA from formalin-fixed and paraffin-embedded tissue samples in an HLA PCR sequence-specific primer and probe (SPP) system, showed that tissue fixed in formalin for less than 3 days and embedded in paraffin can serve as a useful source of DNA for PCR-SPP typing kits.     

MiniSTR multiplex systems based on non-CODIS loci for analysis of degraded DNA samples

We describe two short amplicon autosomal short tandem repeat (miniSTR) quadruplex systems for eight loci D1S1171, D2S1242, D3S1545, D4S2366, D12S391, D16S3253, D20S161, and D21S1437, unlinked from the combined DNA index system (non-CODIS) loci, using newly designed primer sets. The results of an assay of 411 Japanese individuals showed that polymerase chain reaction (PCR) products within the eight loci were less than 150bp in size, without the seven additional bases for adenylation. The frequency distributions in the loci showed no deviations from Hardy-Weinberg equilibrium expectations. The accumulated power of discrimination and power of exclusion for the eight loci were 0.9999999991 and 0.998, respectively. For assay of highly degraded DNA, including artificially degraded samples and the degraded forensic casework samples assessed with the present miniSTR quadruplex systems, the systems proved quite effective in analyzing degraded DNA.     

A case of paternity testing influenced by the silent allele of Rh erythrocyte groups

A paternity test is presented in which a father and his two children possessed an extremely rare amorphic gene R-29 (r,---). One of the children was determined to be illegitimate at the first trial as her Rh phenotype was R2R2(ccDEE) and the father's phenotype was R1R1(CCDee). At the Court of Appeal, however, the rare Rh gene r(---) was shown to be inherited from the father to the appellant child through extended tests including her brother whose phenotype was also R2R2(ccDEE). She was acknowledged to be legitimate.     

Determination of ABO blood groups by radioimmunoassay using 125I-protein A

Since the crystallizable fragment (Fc) portion of the immunoglobulin G (IgG) molecule is the binding site of Protein A, a radioimmunoassay procedure using 125I-Protein A was developed for identification of the ABO blood groups. The isotope level bound to Group A, B, or AB red cells decreased with the dilution of anti-A or -B, respectively. After sensitization by anti-A plus B in Group O serum, the isotope bindings were observed in Groups A, B, and AB cells, while no significant radioactive count appeared in Group O cells. Furthermore, there was little significant isotope binding in both Group A and B red cells sensitized by the serum from Group A or B blood containing mainly IgM anti-A or -B. A radioimmunoassay using 125I-Protein A is an excellent method for identifying ABO blood groups.     

Allelic structure and distribution of two STR loci, D8S580 and D22S442, in the Japanese population

The allelic frequency and structural characteristics of two STR loci D8S580 and D22S442 were investigated using blood samples from 143 unrelated healthy Japanese individuals. Thirty-eight alleles in D8S580 locus and 13 alleles in D22S442 locus were identified. The discrimination power, heterozygosity, and the polymorphic information content of those loci displayed high values (0.98, 0.88, and 0.87 in D8S580 and 0.97, 0.86 and 0.85 in D22S442), and their frequency distributions met Hardy-Weinberg equilibrium expectations. The allelic pattern of D8S580 was complex and differentiated into three groups (group I: alleles 184-194bp; group II: alleles 203-223, 235, 239, 243, 252 and 255bp; group III: alleles 227-286bp). Most of their alleles contained five categories of repeat units (A: aaaag; B: aaag; C: aagg; D: caag; E: agaa). On the other hand, D22S442 contained only two types of repeat units (A: agga; B: aggg). The present study, hence, proves that both D8S580 and D22S442 are highly polymorphic and represent stable genetic markers applicable to forensic investigations.
