: 1.76, n = 3) control counterparts. For correlation of PET imaging data, post-imaging quantitative biodistribution studies were also performed, wherein excised organs were counted for γ activity ...
are known, summarized in [37–39]. In particular, the recovery of Lns from active Ta targets was reported in [40–42]. However, in those studies (mostly involving amounts of Lns in the order of milligrams ...
exactly how, or if, the rs13266634 polymorphism impacts transporter activity . In a study performed in our laboratory,74 we measured Zn2+ accumulation in the vesicle interior using Zinquin after ...
the biological system under study . An important characteristic of PET imaging is that it enables the distribution of the radiotracer to be measured quantitatively, assuming that appropriate corrections are made ...
, Franklin, MA). Measurement of Exofacial Reduced Sulfhydryl Groups Reduced sulfhydryl groups on the root surface (presumably on the plasma membrane surface and/or within the cell wall) of ± Fe-grown pea ...
. The study presents the first demonstration of the parallel operation of K+-sensitive and -insensitive NH4+ flux mechanisms in plants. Ammonium, barley, efflux, influx, nitrogen-13, non-selective cation ...
mouse (0·8 s). Iodinated contrast agents have a short half-life (10 min) in circulation; however, because of faster scan times and the use of clinical contrast agents , perfusion studies may be performed ...
”) and were found to be more negative than measured membrane potentials (ƊΨm) for epidermal and cortical root cells at both K+ conditions (Table I); thus, thermodynamically active K+ uptake was predicted. Since ...
(which did not require activation ), namely selenite. This was a big mistake, as selenite (we later learned) is chemically reduced rapidly and precipitated to Se(0) by our medium's reducing agents (e.g ...
, mice were placed in methacrylate cylinders (20 cm high x 9 cm diameter) positioned on a glass surface . The heat source was positioned under the plantar surface of the hind paw and activated with a light ...
