A COMPARISON OF FLUORESCENCE METHODS USED IN THE PHARMACOKINETIC STUDIES OF Zn(II)PHTHALOCYANINE IN MICE
TLDR
The in vivo measurements at two different anatomical sites showed pharmacokinetic behavior that reflects an overall integrated fluorescence originating from several tissue sites, consistent with previous findings on the pharmacokinetics of ZnPc.
Regulation of o(2) concentration in soybean nodules observed by in situ spectroscopic measurement of leghemoglobin oxygenation.
TLDR
The results support the proposal that nodules adapt to increased external pO(2) by regulating their resistance to O(2)'s diffusion, and help to explain why leghemoglobin levels in intact soybean root nodules were low during development by growth in narrow, glass-walled cuvettes.
ON THE SOURCE OF THE OSCILLATIONS OBSERVED DURING in vivo ZINC PHTHALOCYANINE FLUORESCENCE PHARMACOKINETIC MEASUREMENTS IN MICE
TLDR
Surface‐detected fluorescence spectroscopy can be used to monitor the pharmacokinetics of uptake and clearance of red‐absorbing fluorophores such as zinc(II) phthalocyanine (ZnPc) in vivo, but it is important to be aware of the possibility of such artifactual contributions to in vivo fluorescence pharmacokinetic measurements.
A highly sensitive, flow through h(2) gas analyzer for use in nitrogen fixation studies.
TLDR
A H( 2) gas analyzer is described which is able to accurately and reproducibly detect up to 100 times lower H(2) concentrations than most thermal conductivity gas chromatographs or other conventional instruments used for the measurement of H(1) gas.
