This randomized, double-blind, double-dummy, multicentre cross-over study compared the effects on the hypothalamic-pituitary-adrenal (HPA) axis of fluticasone propionate (750 microg twice daily given via the Diskus) and budesonide (800 microg twice daily given via the Turbuhaler). Two treatment periods of 2 weeks each were preceded by a 2-week run-in period and separated by a 2-week washout per...

The role of neuronal histamine in memory processing. Neuronal histamine(HA) may play a role in memory processing. This hypothesis is based upon evidence that the action of histamine at central H1 and H2 histamine receptor sites has been shown to modulate memory of rats and mice in adversely-motivated tasks. The purpose of this study was to test this hypothesis more thoroughly in mice using two ...

abstract three separate greenhouse experiments were conducted in the greenhouse facilities of the iranian plant protection research institute, tehran, to study the efficacy of some accase inhibiting herbicides for control of resistant based on mechanism, resistance based on enhanced metabolism and susceptible wild oat biotypes. in each experiment, biotypes were treated separately by 17 herbicid...

The establishment of planted trees and the natural regeneration in agroecosystems is challenging. This study evaluated following six native tree species two agricultural systems Atlantic Forest Paraguay: Cedrela fissilis Vell., Cordia trichotoma (Vell) Arráb. ex Steud., Handroanthus albus (Cham.) Mattos, impetiginosus (Mart. DC.) Peltophorum dubium (Sprengel) Taubert, americana (L.) Gottschling...

We examined the cost of conserving species as climate changes. We used a Maxent species distribution model to predict the ranges from 2000 to 2080 of 74 plant species endemic to the forests of Madagascar under 3 climate scenarios. We set a conservation target of achieving 10,000 ha of forest cover for each species and calculated the cost of achieving this target under each scenario. We intervie...

OBJECTIVES This study aimed to compare the quality ratings by cochlear implant (CI) and hearing aid (HA) users in response to musical sounds. DESIGN The ratings of 15 experienced adult Nucleus CI users (using the Advanced Combination Encoder (ACE) or Spectral Peak (SPEAK) strategy) were compared with those of 15 experienced adult HA users who met the audiological criteria for implantation. Ad...
