Peanut and tree-nut allergies have increased dramatically in prevalence, especially children. Historically, children with food been treated through strict avoidance of the allergen. Recently, an oral preparation peanut allergen (Palforzia) was approved for immunotherapy (ie, desensitization) 4 to 17 years old. This article reviews its role allergies.

Murine sarcoma virus-associated protein kinases that bind to actin have been purified by affinity chromatography on actin coupled to Sepharose. Heat inactivation studies showed the presence of thermolabile enzyme activity in pseudotypes containing a temperature-sensitivity mutant of murine sarcoma virus (MSV) but not in two independent wild-type MSV pseudotypes. Studies with Sephadex G-75 colum...

A purification procedure for Neurospora crassa isocitrate lyase (ICL) is described. Thirteen mutants at the acu-3 locus produced no detectable ICL activity either on sucrose as sole carbon source or in the presence of acetate. These mutants also produced little or no protein able to neutralize anti-ICL antibodies. Selection of revertants, able to grow on acetate as sole carbon source, from one ...

Abstract The immunomodulatory properties of probiotics are particularly important at the establishment Th 1-Th 2immune balance early in life. A skewing to response driven by dendritic cell regulation can lead airway alteration during respiratory allergy and virus infection. Previous work from our lab have determined that oral supplementation mice with Lactobacillus johnsonii (Lj) resulted be pr...

The aim of this study was to identify hereditary and acquired risk-factors as they are related to the occurrence of stroke in children. We identified 21 children with stroke. A search of the Factor V Leiden mutation, the Factor II G20210A variant, and the thermolabile variant of methylenetetrahydrofolate reductase was performed in patients and in a control group (n = 115). We identified risk fa...

Preparation of high quality allergen extracts is essential for the diagnosis and immunotherapy of allergic disorders. Standardization of allergen extracts concerns determination of the allergen unit, development of reference material and measurement of the overall IgE binding capacity of an allergen extract. Recently, quantification of individual allergens has been the main focus of allergen st...

Tetraploid strains of Saccharomyces cerevisiae carrying different dosages of the CYR1+ gene have been constructed. Adenylate cyclase activity observed in these tetraploid strains was proportional to the dosage of the active CYR1+ gene. Of the 57 mutants requiring adenosine 3',5'-monophosphate for growth at 35 degrees C, two allelic temperature-sensitive cyr1 mutants produced thermolabile adenyl...

background: allergy to saffron (crocus sativus) pollen has been described in people involved in processing of saffron flower stamens. profilins have been identified as a pan-allergen in different plant pollens and foods. this molecule is an actin-binding pro-tein with a molecular weight of 12-16 kda found in eukaryotic species. objective: the aim of this study was to generate monoclonal antibod...

BACKGROUND Rat allergen has proved to be an important cause of IgE-mediated hypersensitivity in the occupational setting. The prevalence and significance of rat allergen in homes has not been studied. OBJECTIVE The purpose of this study was to determine the prevalence of rat allergen in the homes of inner-city children with asthma and to examine the relationship between rat allergen exposure,...
