introduction: headache is the most common neurologic symptom among referees to the emergency department (ed), while the best treatment has not yet been found. therefore, in the present study pain relief effects of metoclopramide and acetaminophen were compared in patients suffered acute primary headache. methods: this study was a double-blind randomized clinical trial performed in imam khomeini...

This paper investigates absorption and global accessibility under perfect foresight dynamics in games with linear incentives. An action distribution in the society is absorbing if there is no equilibrium path escaping from the distribution, and globally accessible if, from every initial distribution, there exists an equilibrium path which converges to the distribution. Using time symmetry of th...

Frankia strain CcI3 grown in culture produced a hemoglobin which had optical absorption bands typical of a hemoglobin and a molecular mass of 14.1 kDa. Its equilibrium oxygen binding constant was 274 nM, the oxygen dissociation rate constant was 56 s(-1), and the oxygen association rate constant was 206 microM(-1) s(-1).

the one photon absorption (opa) cross section of a current carrying two-orbital quantum dot (qd) with strong electron-phonon interaction (polaron regime) is considered. using the self-consistent non-equilibrium hartree-fock (hf) approximation, we determine the dependence of opa cross section on the applied bias voltage, the strength of effective electron-electron interaction, and level spacing ...

3 H-Spiroperidol, a butyrophenone antipsychotic agent, binds specifically and with high affinity to neuroleptic receptors in the 3 corpus striatum and substantia nigra. Scatchard analysis of Hspiroperidol isotherms in the rat striatum revealed a dissociation constant (KQ) of 30 pM and a total receptor density (Bmax) of 430 fmoles/mg protein. In the substantia nigra, the and Bmax values were 42 ...

BACKGROUND The effect of vasoconstrictors in prolonged cardiopulmonary resuscitation (CPR) has not been fully clarified. OBJECTIVES To evaluate adrenaline and vasopressin pressure effect, and observe the return of spontaneous circulation (ROSC). METHODS A prospective, randomized, blinded, and placebo-controlled study. After seven minutes of untreated ventricular fibrillation, pigs received ...

in this study, the pharmacokinetic parameters of two marketed tablet formulations of ketoconazole were studied, and the relative bioavailability of the test formulation was compared with a reference formulation. a single dose (12x2) double blind randomized cross-over study of a generic formulation of ketoconazole tablet (2x200 mg), and a commercial brand, nizoral tablet (2x200 mg, janssen pharm...
