purpose: patients may control postoperative pain by self-administration of intravenous opioids   using devices designed for this purpose (patient controlled analgesia or pca). this study set out   to determine whether any of the two opioid administrations (i.e. pca or conventional analgesia)   would provide superior pain relief among patients undergoing laparoscopic cholecystectomy   or not.   ...

conclusions intravenous administration of paracetamol immediately after knee arthroscopy improved postoperative pain, decreased analgesic administration, maintained stable hemodynamic parameters, had no complications related to opiates, no nausea and vomiting, and increased patient satisfaction and comfort in comparison to pca with morphine. results there was no significant difference regarding...

the purpose of this review article is to characterize all of the parameters regarding the types, polymers used, and release kinetics of matrix tablets. matrix system was the earliest oral extended release platform for medicinal use. matrix tablets are most commonly used methods to modulate the release profile of drugs. they are much desirable and preferred for such therapy because they offer be...

background: despite major advances in assisted reproductive techniques, the implantation rates remain relatively low. some studies have demonstrated that intrauterine infusion of granulocyte colony stimulating factor (g-csf) improves implantation in infertile women. objective: to assess the g-csf effects on ivf outcomes in women with normal endometrial thickness. materials and methods : in this...

background: many workers suffer from low-back pain. type and severity of spinal complaints have relationship with work load. lack of adherence to ergonomics recommendations among the important causes of low-back pain. objective: to assess the effect of 3 ergonomics training programs on the prevalence of lowback pain among workers of an iranian automobile factory. methods: in a parallel-design 4...

With the expanding demand on application of magnesium alloys in automotive and aerospace industries, robust methods in fatigue characterization of commercially available magnesium alloys with high specific strength is anticipated. In this paper, rotating bending load controlled tests has been studied on specimens machined from an extrusion piece of AZ31B. Due to asymmetric and anisotropic behav...

In combination with randomization, blinding or masking is an important factor in randomized controlled trials (RCTs), particularly in trials that assess therapeutic effects. Here an attempt is made to explain blindness and why it is important. In clinical trials, blinding is defined as the condition imposed on a study in which study participants, health care providers and assessors collecting o...

We describe ongoing work on a bidirectional mapping between Attempto Controlled English (ACE) and OWL DL. ACE is a well-studied controlled natural language, with a parser that converts ACE texts into Discourse Representation Structures (DRS). We show how ACE can be translated into OWL DL (by using the DRS as interlingua) and how OWL DL can be verbalized in ACE. This mapping renders ACE an inter...

The possibility of producing stable oil-in-water (O/W) emulsions containing oil droplets surrounded by multiple layer interfacial membranes from food grade ingredients has been demonstrated. These emulsions were produced using a three stage process that relies on the adsorption of charged biopolymers to oppositely charged surfaces. Emulsions (0.5 wt % corn oil, 0.1 wt % lecithin, 0.0078 wt % ch...

We describe a controlled fragment of English for editing ontologies in OWL. Although this language substantially overlaps other CNLs that have been proposed for this purpose, it has a number of special features designed to simplify its learning and use. First, the language allows users to start typing in sentences with little or no preliminary effort in building a controlled vocabulary or lexic...
