    Beschreibung / Inhaltsverzeichnis: Zusammenfassung Es wurde radioimmunologisch der ß-HCG-Gehalt in insgesamt 58 Abortblutspuren bestimmt. Das Spurenalter betrug bis 45 Wochen. Die Ergebnisse zeigen, daß aufgrund der Stabilität des ß-HCG eine Schwangerschaftsdiagnostik aus älteren Blutspuren möglich ist. Eine Verbesserung der Nachweisbarkeit durch Elution mittels Ultraschall konnte nicht erreicht werden.
    Notizen: Summary Pregnancy was diagnosed from old blood stains by means of radioimmunoassay of ß-HCG. Up to 45 days, the age of the blood stains did not influence values, and extraction by ultrasound did not improve the results.

    The effect of potato starch derived and corn starch derived hydroxyethyl starch on in vitro blood coagulation (1998)
    Oxford : Blackwell Science Ltd
    Anaesthesia 53 (1998), S. 0

    Thema: Medizin
    Notizen: We have compared the effects of progressive in vitro haemodilution (30% and 60%) with potato starch derived hydroxyethyl starch and corn starch derived hydroxyethyl starch on blood coagulation in 80 patients using thrombelastography. Both solutions significantly compromised blood coagulation as evidenced by an increase in coagulation time and decreases in angle α, maximum amplitude and coagulation index (p 〈 0.05). Blood coagulation was more compromised during haemodilution with potato starch derived hydroxyethyl starch as compared with corn starch derived hydroxyethyl starch (p 〈 0.05). When taking the effect of haemodilution with 0.9% saline into account, haemodilution with both hydroxyethyl starch solutions also augmented clot lysis (p 〈 0.05), with potato starch derived hydroxyethyl starch having a greater effect than corn starch derived hydroxyethyl starch (p 〈 0.05). We conclude that potato starch derived hydroxyethyl starch compromises in vitro blood coagulation more than corn starch derived hydroxyethyl starch.

    Haemodilution tolerance in patients with mitral regurgitation (1998)
    Oxford : Blackwell Science Ltd, UK
    Anaesthesia 53 (1998), S. 0 
    Details
    ISSN: 1365-2044

    Thema: Medizin
    Notizen: Haemodynamic parameters and oxygen consumption were determined in 20 patients with mitral regurgitation before and after a 12 mlkg−1 isovolaemic exchange of blood for 6% hydroxyethyl starch. During haemodilution, mean (SEM) haemoglobin concentration decreased from 13.0 (0.4) to 10.3 (0.4) gdl−1 (p = 0.001). With cardiac filling pressures maintained at predilution levels, cardiac index increased from 1.84 (0.08) to 1.94 (0.08) l.min−1.m−2 (p = 0.025) while systemic vascular resistance decreased from 1556 (86) to 1425 (83) dynescm−5 (p = 0.002) and oxygen extraction increased from 31.7 (1.1) to 37.3 (1.4)% (p = 0.001) resulting in an unchanged oxygen consumption. The haemodynamic response to haemodilution was not affected by the patients' cardiac rhythm, i.e. whether it was sinus rhythm or atrial fibrillation. In conclusion, isovolaemic haemodilution to a haemoglobin of 10.3 gdl−1 is well tolerated in patients with mitral regurgitation. Compensatory mechanisms include both an increase in cardiac index and an increase in oxygen extraction.

    VOC Emissions from Cork Products for Indoor Use (1998)
    Oxford, UK : Munksgaard International Publishers
    Indoor air 8 (1998), S. 0 
    Details
    ISSN: 1600-0668
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Architektur, Bauingenieurwesen, Vermessung , Medizin
    Notizen: Abstract Complaints about unpleasant odour from wall, ceiling and floor coverings made of composite cork, induced chamber tests to study the emissions of volatile organic compounds (VOC) from composite cork products for indoor use. Emissions of phenol and furfural were found to be high, particularly those from cork parquet. Emission factors after 1 week ranged from 150 to 650 μg m−2 h−1 and from 15 to 350 μg m−2 h−1 for phenol and furfural, respectively, and decreased only slowly over time, by a factor of approx. 10 for a 6-month period. The ranges of emission factors were found to be similar for some solvents such as cyclohexanone or toluene which are constituents of varnishes used to protect cork surfaces. The emission of furfural may result from chemical reactions in the cork during the production process or may be caused by additives such as binders.

    Total Volatile Organic Compounds (TVOC) in Indoor Air Quality Investigations (1997)
    Oxford, UK : Munksgaard International Publishers
    Indoor air 7 (1997), S. 0 
    Details
    ISSN: 1600-0668

    Thema: Architektur, Bauingenieurwesen, Vermessung , Medizin
    Notizen: Abstract The amount of volatile organic compounds (VOCs) in indoor air, usually called TVOC (total volatile organic compounds), has been measured using different definitions and techniques which yield different results. This report recommends a definition of TVOC referring to a specified range of VOCs and it proposes a method for the measurement of this TVOC entity. Within the specified range, the measured concentrations of identified VOCs (including 64 target compounds) are summed up, concentrations of non-identified compounds in toluene equivalents are added and, together with the identified VOCs, they give the TVOC value.The report reviews the TVOC concept with respect to its usefulness for exposure assessment and control and for the prediction of health or comfort effects. Although the report concludes that at present it is not possible to use TVOC as an effect predictor, it affirms the usefulness of TVOC for characterizing indoor pollution and for improving source control as required from the points of view of health, comfort, energy efficiency and sustainability.

    Common allergenic structures in hazelnut, rye grain, sesame seeds, kiwi, and poppy seeds (1993)
    Oxford, UK : Blackwell Publishing Ltd
    Allergy 48 (1993), S. 0 
    Details

    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Medizin
    Notizen: Allergy to kiwi, poppy seeds, and/or sesame seeds often occurs in patients with a simultaneous sensitization to nuts and flour. Previously cross reactions have been verified by RAST inhibition. In this study the nature of this cross-reactivity is further characterized by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE), followed by immunoblotting to nitrocellulose. The degree of cross-reactivity among kiwi, sesame seeds, poppy seeds, hazelnuts, and rye grain was found to be very high in the patients studied. The existence of both cross-reacting and unique components was observed; however, the cross-reacting and unique components could be different for different patients.

    Baseline staging in cutaneous malignant melanoma (2004)
    Oxford, UK : Blackwell Science Ltd
    British journal of dermatology 150 (2004), S. 0 
    Details
    ISSN: 1365-2133
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Medizin
    Notizen: Background  Baseline staging in patients with primary cutaneous malignant melanoma (MM) is routine, but the diagnostic accuracy and the impact on clinical outcome are still unclear.Objectives  To evaluate the sensitivity and specificity of baseline staging in the early detection of regional lymph node metastases or distant metastases in patients with MM.Methods  One hundred consecutive patients with MM of Breslow's tumour thickness over 1·0 mm were enrolled. All patients had an extensive baseline staging including physical examination, ultrasound (US) of the abdomen and regional lymph nodes, chest X-ray, whole-body positron emission tomography (PET) and sentinel lymph node biopsy. The sensitivity and specificity of detection of macroscopic or microscopic metastases in the regional lymph nodes or at distant sites were calculated for each method.Results  Sentinel lymph node biopsy was positive in 26 patients. US detected two of 26 histologically tumour-positive sentinel nodes (sensitivity 8%, specificity 88%) and PET two of 26 (sensitivity 8%; specificity 100%). There were three lymph node metastases with a diameter 〉 4 mm. All of them were found suspect at physical examination. Two of them were detectable with US, two with PET, and all were identified with either US or PET. Nine patients had suspect findings at distant sites, which were all false positive on further investigation (specificity of the combined staging procedures 91%). At 18 (6–37) months' follow-up, five of 26 (19%) patients with a positive sentinel node and four of 74 (5%) of patients with a negative sentinel node had recurrent or progressive disease.Conclusions  The combination of physical examination and lymph node US detects the great majority of patients with macroscopic lymph node metastasis (approximately 3% of patients at baseline). Only 10% of patients who have a histologically tumour-positive sentinel node are macroscopically detectable. Altogether, approximately 25% of patients have a positive sentinel node biopsy, among 90% microscopic. The value of whole body staging at baseline remains limited, since distant metastases can hardly ever be detected. The survival benefit of baseline staging and surveillance in patients with cutaneous MM remains to be established by comparative prospective trials.
