    A lack of effect of captopril on platelet aggregation in patients with congestive heart failure (1991)

    Notes: Summary We have studied the acute and chronic effects of an ACE inhibitor (captopril) on platelet function and the renin-angiotensin system in patients with congestive heart failure. Plasma concentrations of angiotensin II fell significantly after a single dose of captopril (25 mg) and during long-term treatment with captopril (2 weeks, 75 mg/day). Plasma renin activity increased significantly after both the single and repeated doses. Captopril did not affect ADP-induced platelet aggregation or concentrations. It seems unlikely that circulating angiotensin II affects ADP-induced platelet aggregation in patients with congestive heart failure.

    Production of a thermostable ATPase by the facultative thermophile, Bacillus coagulans (1983)
    Springer
    Archives of microbiology 135 (1983), S. 74-76 
    Details
    ISSN: 1432-072X
    Keywords: ATPase ; Bacillus coagulans ; Facultative thermophile ; Thermoadaptation

    Topics: Biology
    Notes: Abstract The properties of the ATPase in the facultative thermophile, Bacillus coagulans, grown at thermophilic or mesophilic temperatures were similar. Arrhenius plots did not show discontinuities indicative of thermoadaptation. Magnesium stimulation of the enzyme was dependant on the assay temperature but independant of the growth temperature. The ATPase in cells grown at 35°C or 55°C was equally thermostable at 65°C. In contrast, the ATPase from the mesophile, Bacillus megaterium (T max=42°C) was completely inactivated at 55°C in 5 min.

    The respiratory chain of the facultative thermophile, Bacillus coagulans (1986)
    Springer
    Archives of microbiology 145 (1986), S. 347-352 
    Details
    ISSN: 1432-072X
    Keywords: Bacillus coagulans ; Facultative thermophile ; Respiratory chain ; Inhibitors ; Cytochromes

    Topics: Biology
    Notes: Abstract Two oxidases were found to be present in membranes from the facultative thermophile Bacillus coagulans grown at 55°C, compared to one in cells grown at 37°C. Cytochrome spectra and inhibitors of the respiratory chain identified them as cytochrome oxidases aa 3 and d. Both were present in membranes from 55°C grown cells, but only cytochrome oxidase aa 3 was found in membranes from 37°C grown cells. The presence of cytochrome d in 55°C grown cultures was found to be due to decreased oxygen tension and not to the high growth temperature. This was confirmed by (a) induction of cytochrome d at 37°C under conditions of oxygen limitation and (b) its repression at 55°C under conditions of high aeration and its subsequent induction on lowering the dissolved oxygen concentration in chemostat cultures. Two cytochromes b (λmax 558 and λmax 562) were present in both 37°C and 55°C grown cells. Results from the inhibition of substrate oxidation by membranes suggested different pathways of electron transport by the respiratory chain.
