    Effects of cooling and heating of the tooth on pulpal blood flow in man (1994)
    Oxford, UK : Blackwell Publishing Ltd
    Dental traumatology 10 (1994), S. 0

    Topics: Medicine
    Notes: Abstract Laser Doppler flowmetry (LDF) was used to study the changes in pulpal blood flow (PBF) evoked by application of cold or heat to the palatinal surfaces of teeth 11 or 21 in nine young subjects. Switching from a thermode temperature of 33° to 5° G on average induced a slow decrease of PBF to about 80% of control, and also warming to 39°C evoked a small reduction in most subjects. Inter individual differences were large, however, and both cooling and warming sometimes triggered a rise in PBF. In contrast, skin blood flow, as recorded with LDF in the forearm, invariably rose during warming and fell during local cooling. The results suggested a more complex interaction between local and nervously mediated effects of moderate changes in temperature in the tooth pulp than skin, and that the previous held view of cold and heat decreasing and increasing PBF, respectively, is wrong.

    Reproducibility and prognostic value of histologic type and grade in early epithelial ovarian cancer (1993)
    238 Main Street, Cambridge, Massachusetts 02142, USA : Blackwell Scientific Publications
    International journal of gynecological cancer 3 (1993), S. 0 
    Details
    ISSN: 1525-1438
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Medicine
    Notes: From September 1981 to September 1986, 417 consecutive treated patients with epithelial ovarian cancer FIGO stage I and II were registered by the Danish Ovarian Cancer Group (DACOVA). Typing and grading were primarily performed by several pathologists, with and without training in gynecologic pathology. Review typing by one specially trained pathologist showed an agreement rate of 72% for serous and endometrioid carcinoma, 86% for mucinous and 100% for clear cell carcinoma. The agreement rate was calculated for patients primarily classified by pathologists trained in gynecologic pathology and for patients primarily classified by pathologists with and without training. The agreement rate was not better for the group of pathologists with special training in gynecologic pathology. Grading was performed according to two classifications: one based on architectural pattern and one on combined criteria. Review grading showed an agreement rate of 77% for architectural classification and an agreement rate of 52% for combined classification. The agreement rate between the two grade classifications at review was only 62%. Combined grading showed a significant tendency towards classifying more tumors as low grade. All grade classifications had prognostic value. The poor agreement rate of both type and grade even when performed by pathologists with expertise in gynecologic pathology, calls for a better and more reproducible characterization of malignant ovarian tumors.

    Foetal antigen 2 (FA2) in relation to wound healing and fibroblast proliferation (1992)
    Oxford, UK : Blackwell Publishing Ltd
    British journal of dermatology 126 (1992), S. 0 
    Details
    ISSN: 1365-2133
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Medicine
    Notes: During wound healing of human skin the deposition of foetal antigen 2 (FA2) and basement membrane (BM) components collagen type IV and collagen VII was followed. FA2 appeared on day 8 in the cytoplasm of proliferating fibroblasts and around newly formed blood vessels. As granulation tissue was formed, FA2 was seen diffusely in the loose matrix and in proliferating fibroblasts. Reestablishment of FA2 as a broad diffuse band along the BM at the dermo-epidermal junction was seen on day 22. In contrast, type IV and VII collagen were found along the BM and in the basal cells of the newly formed epithelium and a continuous linear BM distribution of these two components were reestablished by days 12 and 14, respectively. The molecular weight (Mr) analysis of FA2, isolated from human skin fibroblast culture supernatants using SDS–PAGE, revealed a Mr of 27 kDa, corresponding to that of FA2 isolated from amniotic fluid.The presence of FA2 in proliferating fibroblasts and diffusely in the newly formed matrix of granulation tissue, as well as its late appearance at the BM after this had become established, suggests that FA2 takes part in connective tissue metabolism and perhaps tissue morphogenesis.

    In vitro breakdown of gingival tissue by elastase from human polymorphonuclear leukocytes An electron microscopic study (1982)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of periodontal research 17 (1982), S. 0 
    Details
    ISSN: 1600-0765
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Medicine
    Notes: Several biopsies of human marginal gingiva were collected from clinically healthy and from slightly inflamed sites. The biopsies from one given site were divided and treated as follows: one portion was immediately fixed and used as a reference; the others were incubated for two hours either in culture medium alone, or in the same medium with different concentrations of elastase purified from human polymorphonuclear leukocytes. The biopsies were then fixed and examined by electron microscopy. It was found that elastase caused an enlargement of the intercellular spaces of the oral gingival epithelium, interruptions of the basement lamina, and loss of collagen in the underlying connective tissue.Biopsies collected from severely inflamed sites were also studied in the electron microscope. Some of the ultrastructural alterations observed in these inflamed tissues were similar to those experimentally induced by elastase.

    Techno-economic paradigms as typical interfaces between producers and users (1991)
    Springer
    Journal of evolutionary economics 1 (1991), S. 119-144 
    Details
    ISSN: 1432-1386
    Source: Springer Online Journal Archives 1860-2000
    Topics: Economics
    Notes: Abstract In this paper it is suggested that techno-economic paradigms should not only be considered as means of coordination among the producers of technological knowledge but also as means of coordination between groups of producers and users of specific types of artefacts, as shared specifications of typical interfaces between the two parties. If such interfaces are simplified and standardized, the information needs of the parties will be delimited (and this is necessary in the worlds of bounded rationality à la Simon and Hayek). However, successful product innovation will often presuppose an information-rich interaction and thereby often presuppose non-standardized interfaces. In the paper these two conflicting principles are developed in order to clarify several controversial issues within the theory of innovation and evolution.
