A novel scheme for the focusing of high-energy leptons in future linear colliders was proposed in 2001 [P. Raimondi and A. Seryi, Phys. Rev. Lett. 86, 3779 (2001)]. This scheme has many advantageous properties over previously studied focusing schemes, including being significantly shorter for a given energy and having a significantly better energy(More)
Impromidine (1) is a potent and selective histamine H2 receptor agonist and its structure comprises a strongly basic guanidine group containing two different imidazole-containing side chains. In this paper we report the synthesis of analogues in which both of the side chains and the guanidine group are modified and tested as agonists or antagonists at(More)
In the histamine H2-receptor antagonist metiamide (2a) isosteric replacement of thione sulfur (=S) by carbonyl oxygen (=O) or imino nitrogen (=NH) affords the urea 2c and guanidine 2d which are antagonists of decreased potency. The guanidine is very basic and at physiological pH is completely protonated. However, introduction of strongly electronegative(More)
Measurements of kaons, pions and protons identified using the dE/dx technique have been made in deep-inelastic scattering ep interactions at HERA in the kinematic range 5 < Q < 70 and 10−5 < x < 10−2. Tests of QCD were made possible through the production of transverse momenta and pseudo-rapidity spectra with comparisons made to ARIADNE and LEPTO Monte(More)
A sensitive gas chromatographic method for the determination of guanabenz[(2,6-dichlorobenzylidene)amino]guanidine in urine and plasma was developed. The method depends upon the acid hydrolysis of guanabenz to 2,6-dichlorobenzaldehyde, which has strong electron capturing properties and is volatile enough to be eluted from a gas chromatographic column.(More)
The pharmacokinetics of guanabenz (16 mg) and hydrochlorothiazide (25 mg), administered separately and as a fixed-combination tablet (guanabenz 16 mg/hydrochlorothiazide 25 mg), were compared in a randomized three-period crossover study in 24 healthy men. Plasma concentrations were monitored for 48 h after each administration. No statistically significant(More)
