this experiment was conducted to evaluate the effects of different levels of zinc on the performance and humoral immunity response in broiler chickens with 250 ross broiler chickens with five experimental treatments consisted of five replicates in a completely randomized design. treatments were diets containing: basal diet (control) and basal diet plus 40, 80, 120 and 160 mg zn/kg. results of t...

ion/generalization: thinking at high level, e.g. ability to view two different systems as being the same representation: modeling the ideas and entities that are being dealt with, e.g. shapes as strings algorithm: finding ways and methods to ahieve what is needed (this is not always possible) program: representation or encoding of an algorithm, usually machine dependent, e.g. the same addition ...

BACKGROUND Information is lacking concerning optimal infusion rates of crystalloid during resuscitation from acute haemorrhage. In this study, a mathematical model was used to predict infusion volume of crystalloid needed to restore and maintain blood volume after acute haemorrhage. METHODS The scenario was a haemorrhage of 15 ml kg(-1) over 30 min in a 70 kg man. A bolus of crystalloid was a...

Inhalation of nebulized furosemide has been shown to alleviate breathlessness provoked experimentally in health and disease; however, it remains unclear whether the efficacy of nebulized furosemide on breathlessness is dose-dependent. We tested the hypothesis that inhaled nebulized furosemide would be associated with a dose-dependent relief of breathlessness during exercise testing in the setti...

The aim of the present study was to investigate the pharmacokinetic and pharmacodynamic characteristics of febuxostat following the administration of single and multiple oral doses under fasting conditions to healthy individuals. Thirty-six healthy subjects were randomly divided into three groups, each containing 12 subjects (six male and six female) as follows: Group A, treated with a single o...
