    Some sources of error in the calculation of relative change in plasma volume (1982)
    Springer
    European journal of applied physiology 50 (1982), S. 13-21 
    Details
    ISSN: 1439-6327
    Schlagwort(e): Plasma volume ; Haematocrit ; Haemoglobin ; F-cell ratio

    Thema: Medizin
    Notizen: Summary The effects of alterations in the F-cell ratio (i.e., the ratio of the whole body haematocrit to the peripheral haematocrit) on calculations of relative (percentage) change in plasma volume have been considered. Errors introduced by failing to correct the measured haematocrit for an assumed value for the F-cell ratio are small, and are negligible compared with the random measurement errors. Errors introduced by a change in the value of the F-cell ratio from some control value to a new value during an experimental procedure (such as exercise or exposure to heat stress) are large, and could lead to gross misrepresentations of the direction and magnitude of any induced change in intravascular volume, and of solute concentration changes assumed to reflect only loss or gain of fluid by the intravascular space.

    Thema: Medizin
    Notizen: Summary High precision blood and plasma densitometry was used to measure transvascular fluid shifts during water immersion to the neck. Six men (28–49 years) undertook 30 min of standing immersion in water at 35.0±0.2

    Effect of posture on arterial baroreflex control of heart rate in humans (1986)
    Springer
    European journal of applied physiology 55 (1986), S. 367-373 
    Details
    ISSN: 1439-6327

    Thema: Medizin
    Notizen: Summary Altered baroreflex function may contribute to the cardiovascular changes associated with weightlessness. Since central blood volume (CBV) increases during simulated weightlessness, we have examined the possibility that acute changes in CBV may modify baroreceptor function. We used graded head-up tilt (HUT) and head-down tilt (HDT) to induce changes in CBV, and neck suction to stimulte carotid baroreceptors, in 6 subjects. The increase in pulse interval induced by a negative pressure of 8.2 kPa (62 mm Hg) imposed for 10 s while supine was compared with the increase while tilted for 8 min at ± 15

    Electrospray tandem mass spectrometry in the diagnosis of organic acidemiasPaper presented in part at the British Mass Spectrometry Society Meeting, Canterbury, 1993. (1994)
    New York, NY : Wiley-Blackwell
    Rapid Communications in Mass Spectrometry 8 (1994), S. 129-133 
    Details

    Thema: Physik
    Notizen: A novel procedure based on electrospray tandem mass spectrometry (ESI-MS/MS) has been used in the diagnosis of organic acidemias. The method is based on the determination of acylcarnitine profiles from blood spots collected on Guthrie cards. The acylcarnitines are extracted with methanol, derivatized to their butyl esters and analyzed by ESI-MS/MS. Precursor-ion scanning of the common fragment at m/z 85 of the butyl esters yields highly diagnostic acylcarnitine profiles. Analysis time is one minute per sample and is fully automated. Examples are given of normal profiles, of profiles from two patients with fatty acid oxidation defects, and of a case of propionic acidemia. The technique is simple, rapid and specific, and shows potential for routine application in neonatal screening of organic acidemias.

    Analysis of the squalestatins by on-line packed capillary liquid chromatography combined with electrospray mass spectrometry (1993)
    New York, NY : Wiley-Blackwell
    Rapid Communications in Mass Spectrometry 7 (1993), S. 953-956 
    Details
    ISSN: 0951-4198
    Schlagwort(e): Chemistry ; Analytical Chemistry and Spectroscopy

    Thema: Physik
    Notizen: A mixture of four squalestatins was separated anil characterized by gradient packed capillary liquid chromatography combined with electrospray collision-induced dissociation mass spectrometry (ESI/CID/MS). Negative-ion ESI was found to afford spectra typified by strong pseudo-molecular ions but providing little structural information. Structural information was obtained using an ion-focusing RF-only octapole lens to provide conditions for CID. The new method showed improvements in sensitivity when compared to existing thermospray and dynamic liquid secondary-ion mass spectrometry methods.

    Thema: Chemie und Pharmazie
    Notizen: The kinetics of the binding of the neurotoxin acrylamide to the cysteine residue of glutathione has been studied. At 37 °C and pH 7.3 the second order rate constant has been determined to be 0.72 ± 0.06 mol-1 dm3 min-1 by thermospray mass spectrometry. The critical energy at pH 11.5 measured over the temperature range 10-37°C by fast atom bombardment mass spectrometry was measured as 24.6 kJ mol-1.
