Other claims from this paper (14)
- Observation Calcium uptake increased for 3 to 6 minutes then leveled off or declined.
- Intervention effect Aluminum decreased net calcium uptake.
- Intervention effect Verapamil decreased net calcium uptake.
- Intervention effect Bepridil decreased net calcium uptake.
- Intervention effect Aluminum plus bepridil caused a more pronounced calcium uptake decrease.
- Intervention effect Aluminum did not aggravate verapamil-associated calcium uptake reduction.
- Intervention effect Erythrosin B increased calcium uptake.
- Intervention effect Calmidazolium increased calcium uptake.
- Intervention effect Their uptake-increasing effect was undetectable with aluminum.
- Intervention effect Mycophenolic acid decreased calcium uptake.
- Intervention effect Guanosine alleviated the mycophenolic acid effect.
- Intervention effect Mycophenolic acid did not aggravate aluminum-associated uptake reduction.
- Intervention effect Calcium uptake was generally lower at pH 4.5 than pH 5.5.
- Mechanism Authors conclude aluminum interferes with guanosine triphosphate-binding proteins.
