(15) It is concluded from these results that selenate is transported actively by the ileal mucosa and that a common transport mechanism for selenate and sulfate exists.
(16) Chromatographic parameters were optimized to determine selenate (SeO4(2-)) by single-column ion chromatography with the simultaneous detection of Cl-, NO2-, NO3- and SO4(2-).
(17) The other, a Pseudomonas species, was shown to respire selenate to selenite.
(18) Young striped bass (Morone saxatilis) with uninflated gas bladders were less sensitive to selenate and more sensitive to selenite exposure than normally developing striped bass in 96-hour acute toxicity tests.
(19) The D-glucose uptake was also stimulated by metavanadate, but not by selenite, selenate, or molybdate.
(20) Selenium transport across the ileum did not occur against a concentration gradient when selenite instead of selenate was present in the incubation medium.
Splenic
Definition:
(a.) Of or pertaining to the spleen; lienal; as, the splenic vein.
Example Sentences:
(1) Reactive metabolites which suppress splenic humoral immune responses are thought to be generated within the spleen rather than in distant tissues.
(2) Hyperimmunization with the tick encephalitis and Western horse encephalomyelitis viruses reproduced in the brain of albino mice, intensified the protein synthesis in the splenic tissue during the productive phase of the immunogenesis (the 7th day).
(3) Gamma-irradiated splenic homogenates of armadillos infected with M. leprae proved sterile by conventional tests and media.

(9) A pathogenetic mechanism is postulated to explain the subacute evolution of fluid collection with diffusion of proteolytic enzymes between the splenic capsule and parenchyma.
(10) Furthermore, effector TH cells within the two compartments exert differential effector activities: splenic effector TH cells induce B cells to both proliferation and maturation, while thymic effector TH cells are defective in activating B-cell maturation.
(11) Splenectomy and splenic artery ligation were performed.
(12) Three patients recovered from their operations, and the other two, both with endocarditis, died postoperatively from causes unrelated to splenic abscess and splenectomy.
