The effect of major cation activity (Ca 2+ , Mg 2+ , Na + , K + ) on Ni toxicity, with dose expressed as exposure (total dissolved Ni concentration Ni Tot ) or free Ni ion activity (in solution Ni 2+ ), or as tissue residue (Ni concentration in plant tissue Ni Tiss ) to ...
The effect of major cation activity (Ca2+, Mg2+, Na+, K+) on Ni toxicity, with dose expressed as exposure (total dissolved Ni concentration NiTot) or free Ni ion activity (in solution Ni2+), or as tissue residue (Ni concentration in plant tissue NiTiss) to the aquatic plant Lemna ...
Canonical olfactory signal transduction involves the activation of cyclic AMP-activated cation channels that depolarize the cilia of receptor neurons and r... GM Billig,B Pál,P Fidzinski,... - 《Nature Neuroscience》 被引量: 327发表: 2011年 Anoctamin/TMEM16 family members are Ca2+-activated Cl...
Goldman–Hodgkin–Katz equation [27] determines the ratio of cation to anion (PK+/PCl-) to be 7 ± 2 for nMOMP and within the error identical for rMOMP (6 ± 1). Similarly, measurements were performed in the presence of 8-fold calcium chloride (0.1 M CaCl2 versus 0.8 M CaCl2) and...

Nuclei of the hippocampal neurons also expressed a variety of spontaneously active cation and anion channels. One of their conclusions was that the nuclear envelope of these neurons is specialized to release Ca2+ into the nucleoplasm and therefore represents an additional level of regulation in the ...
Vesicles were pre- loaded with either sucrose or the cation to be tested and incubated for 1 h with 4 5 ~ a 2(+1 pM) and A23187 in the same buffer. Binding was highest in the absence of cations (sucrose medium) (Table 2). Cations inhibited in 12 Sec 30 sec Flpre 5. Effect ...
Aberrations in such functions are believed to underlie many disease states in the brain, as swell-activated anion channel can be involved in the release of glutamate after a stroke or trauma exacerbating excitotoxic damage and causing neuronal cell death14, 20. Thus, the r...
current of ORNs. Both currents are anionic, present similar dependence on the intracellular Ca2+ concentration, partly inactivate over time, have the same anion permeability sequence, the same sequence of inhibitory efficiency of blockers, the same almost linear I–V relationships and finally both ...
The aerated jar test experiments were conducted with (a) raw groundwater, (b) after increasing the concentrations of HPO42−, Ca2+, Mg2+, or (c) after decreasing the concentrations with either anion or cation exchange resin. 2. Materials and methods 2.1. Chemicals and stock solutions Fe2...
