Methods During general anaesthesia exposure to a number of different agents is common. In addition, anti-inflammatory drugs, antiemetics, antacids, antibiotics and analgesics may be used, and all may elicit reactions. Follow up is recommended to include serum tryptase, specific IgE, skin prick test (SPT), intradermal tests (IDT), basophil activation test (BAT) and provocations. We present a cas...

BACKGROUND A major problem of venom-specific immunotherapy (VIT) is the absence of reliable parameters for deciding treatment discontinuation. AIM OF THE STUDY Intracutaneous tests (ICTs), the basophil activation test (BAT), specific IgEs (sIgEs) and blocking factor (BF) activity were measured during VIT. We made an evaluation by means of a protective index (PI) including ICT, BAT and BF valu...

Background. An in vitro basophil activation test, based on the detection of CD63 upregulation induced by NSAIDs, has been described. Its clinical significance remains controversial. Objectives. In patients with a history of nonallergic NSAID hypersensitivity, stratified according to the severity of the symptoms, to assess with NSAIDs the predictive value of basophil (BAT) and monocyte (MAT) act...

this thesis attempts to investigate the effects of prelistening activities on enhancing iranian efl learners` listening comprehension. the present study investigated ways in which learners` background knowledge could be activated in order to enhance their l2 listening comprehension by limiting the number of possible text interpretations prior to listening. the experiments conducted in this study examined the effect of prior knowledge and vocabulary teaching on iranian efl learners listening comprehension. the current study has two purposes: one is to investigate the effect of background knowledge on the second language listening comprehension of iranian intermediates and the other is to determine whether second language is facilitated by the introduction of unknown vocabularies in the form of prelistening activities. to conduct the study different instruments such as listening proficiency test and four listening tests such as pre and posttests were used and various statistical processes and techniques including paired-sample t-test, and analysis of variance (anova) were used. the findings of this study supported all three hypotheses tested. differences were found between the means of preteaching vocabulary variable, the background knowledge activation variable, and mean difference between these two strategies variable. subjects scored higher when the unknown words were taught in advance. likewise, subjects scored higher when they were asked some relevant questions about the topic than on those without them. there was, in addition, a significant difference between the means of preteaching vocabulary strategy and background knowledge activation strategy. in fact, preteaching vocabulary had a better effect in enhancing the students’ listening comprehension, in comparison to background knowledge activation strategy.

INTRODUCTION The impact of processing on the allergenicity of peanut (Arachis hypogaea) proteins has traditionally been studied using immunoglobulin (Ig) E binding assay. However, as this technique does not assess the potential of an allergen to trigger basophils and mast cells, studies based on it can hardly be considered complete. We evaluated the effect of processing on peanut allergenicity ...
