Ejaculation was pharmacologically induced in a 13-year-old Quarter Horse stallion with a spiral fracture of the radius. The owners desired to have semen from the stallion frozen prior to euthanatizing the horse, but because of the debilitating injury, standard methods of semen collection could not be used. With the stallion standing quietly in a stall, a plastic collection bag was positioned ov...

A new series of tetrahydro-quinazoline and tetrahydro-1H-dibenzo[b,e][1,4]diazepine analogs were synthesized and tested for their DHFR inhibition and in vitro antitumor activity. Compound 35 showed a remarkable DHFR inhibitory potency (IC₅₀, 0.004 μM) which is twenty fold more active than methotrexate (MTX). Compounds 17 and 23 proved to be fifteen fold more active than the known antitumor 5-FU...

BACKGROUND Several interventions are available for management of obsessive-compulsive disorder in adults, but few studies have compared their relative efficacy in a single analysis. We aimed to simultaneously compare all available treatments using both direct and indirect data. METHODS In this systematic review and network meta-analysis, we searched the two controlled trials registers maintai...

Caffeine undergoes 3-N-demethylation via CYP1A2, as well as 1-N-demethylation, 7-N-demethylation and 8-hydroxylation, which may involve other CYP isoenzymes. The aim of the present study was to investigate the influence of clomipramine, desipramine, sertraline, nefazodone and mirtazapine on cytochrome P-450 activity measured by caffeine oxidation in rat liver microsomes. The obtained results sh...

INTRODUCTION To determine the incidence of treatment-induced sexual dysfunction in depressed outpatients treated with five different antidepressants. METHODS 100 depressed patients (ICD-10 criteria for depressive episode, recurrent depressive disorder, and dysthymia) with an active sex life were assessed by the MADS, the CGI, and the Sexual Function Questionnaire at baseline and at 1, 2, and ...

1. Modafinil, a putative central alpha 1 adrenergic agonist, was tested in idiopathic hypersomnia and narcolepsy. 2. Sleep attacks and drowsiness were significantly decreased in 83% of 18 hypersomniac subjects and 71% of 24 narcoleptics. 3. When cataplectic episodes were not totally suppressed the association of a low dose of Clomipramine was successful in improving them. 4. Modafinil, used for...

Serotonin syndrome (SS) is a potentially life-threatening condition associated with increased serotonergic activity in central nervous system and may occur during the use of serotonergic drugs. Although increasing frequency of serotonergic drug use in children, pediatricians, emergency medicine and pediatric intensive care specialists have not enough knowledge and experience about SS that is a ...

Clomipramine (CLM) and oxethazaine (OXZ) were previously reported to increase portal pressure by contracting portal vein branches (PVBs) in isolated perfused rat liver. In the present study, to characterize the contractile mechanisms, the effects of Y27632, HA1077, staurosporine, papaverine, SKF96365, and sulindac sulfide on the portal pressure increase induced by CLM and OXZ were examined comp...
