(12) analyzed galantamine on an RP-C18 column with a mobile phase containing 5% MeCN, 20% acetate buffer at pH 3.5, and 0.025 [mL.sup.-1] diethylamine
as well as on an SCX column using an 8% MeCN and phosphate buffer at pH 2.5 mixture as mobile phase in L.
It has been observed that NO donor diethylamine
(DEA) decreases contractions of the right atrium, but there is no effect on the papillary muscles (Figure 5) (20).
Briefly, a solution of palladium(II) acetate [Pd[(OAc).sub.2]; 32 mg] and triphenylphosphine (PPh3 ;70 mg) in diethylamine
(16 mL) was stirred under argon (Ar) for 10 min at room temperature (rt, 25[degrees]C).
(12) showed a biphasic relationship in which higher concentrations of NO donors (S-nitroso-N-ncetyl-D, L-penicillamine, diethylamine
NONOate, and diethylenetriamine NONOate) decreased testosterone production while lower concentrations of these compounds increased hormone levels.
The filtrate in orange was reacted with 0.1 mol of diethylamine
Further chain extension was completed by the drop-wise addition of ethylenediamine and diethylamine
In this respect, there are different modification methods, and these can be done using various organic agents (epichlorohydrin, N, N-dimenthylformamide, formaldehyde, ethylenediamine, diethylamine
, and trimethylamine)  or some quaternary ammonium compounds .
Alkaline additives to mobile phases, mostly organic amines such as diethylamine
, triethylamine, or dimethyloctylamine, are applied to suppress the ionization of the analyte and as silanol blockers [14, 15].
We observed the formation of cytonemes in human neutrophils upon the inhibition of vacuolar-type ATPase, the blocking of glucose metabolism, the inhibition of GTPase dynamin, or in the presence of nitric oxide donor diethylamine
NONOate or cytochalasin D [18, 21, 22, 25-27].

Ice was applied to the site of inflammation for ten minutes, twice daily, and an ointment based on escin (10mg [g.sup.-1]) and diethylamine
salicylate (50mg [g.sup.-1]) was applied twice daily to help resolve signs of hypersensitivity.
