Predicting the allergenicity of novel proteins is challenging due to the absence of validated predictive methods and a well-defined reference set of proteins. The prevalence of sensitization could be a parameter to select reference proteins to characterize allergenic proteins. This study investigated whether the prevalence of sensitization of...

Scope: No accepted and validated methods are currently available which can accurately predict protein allergenicity. In this study, the role of digestion and transport on protein allergenicity is investigated. Methods and results: Peanut allergens (Ara h 1, 2, 3, and 6) and a milk allergen (β-lactoglobulin) are transported across pig intestinal...

Background: Food proteins differ in their allergenic potential. Currently, there is no predictive and validated bio-assay to evaluate the allergenicity of novel food proteins. The objective of this study was to investigate the potential of a human peripheral blood mononuclear cell (PBMC) gene expression assay to identify biomarkers to predict...

The oral mucosa is the first immune tissue that encounters allergens upon ingestion of food. We hypothesized that the bio-accessibility of allergens at this stage may be a key determinant for sensitization. Light roasted peanut flour was suspended at various pH in buffers mimicking saliva. Protein concentrations and allergens profiles were...

Sensitization and allergy to legumes can be influenced by different factors, such as exposure, geographical background, and food processing. Sensitization and the allergic response to legumes differs considerably, however, the reason behind this is not yet fully understood. The aim of this study is to investigate if there is a correlation...

Six commercial peanut enzyme-linked immunosorbent assay kits were assessed for their ability to recover peanut from the standard reference material 2387 peanut butter and also for their specificity in detecting four major peanut allergens, Ara h 1, Ara h 2, Ara h 3, and Ara h 6. The percentage recovery of peanut from peanut butter differed...

This study describes the international ring trial of the epidermal-equivalent (EE) sensitizer potency assay. This assay does not distinguish a sensitizer from a non-sensitizer, but may classify known skin sensitizers according to their potency. It assesses the chemical concentration resulting in 50% cytotoxicity (EE-EC50) or the 2-fold increase...

At present, the identification of potentially sensitizing chemicals is carried out using animal models. However, it is very important from ethical, safety and economic point of view to have biological markers to discriminate allergy and irritation events, and to be able to classify sensitizers according to their potency, without the use of...

In this article we develop a dialogue model for robot technology experts and designated users to discuss visions on the future of robotics in long-term care. Our vision assessment study aims for more distinguished and more informed visions on future robots. Surprisingly, our experiment also led to some promising co-designed robot concepts in...

The object of the current study was to determine whether static contraction of proximal musculature has an effect on the blood flow more distally in the upper extremity. Static contractions of muscles in the neck shoulder region at three levels (relaxed, shoulders elevated and shoulders elevated loaded with 4.95 kg each) were combined with...

Osteopontin (OPN) has been identified as the most prominent cytokine-encoding gene expressed within multiple sclerosis (MS) lesions. Recently, we demonstrated that OPN plasma levels were elevated in active relapsing-remitting (RR) MS patients. In this longitudinal study, a trend was observed for OPN serum levels in relation to clinical...

Cannabinoids can modulate the function of immune cells. We here present the first human in vivo study measuring immune function in 16 MS patients treated with oral cannabinoids. A modest increase of TNF-α in LPS-stimulated whole blood was found during cannabis plant-extract treatment (p=0.037), with no change in other cytokines. In the subgroup...

In the search for proteins that might play a role in the pathogenesis of multiple sclerosis (MS), osteopontin (OPN) has been identified as the most prominent cytokine-encoding gene expressed within MS lesions. Here, we report significantly increased OPN protein levels in plasma of relapsing-remitting MS patients. In contrast, OPN protein levels...

Een belemmerde bloedtoevoer naar werkende spieren wordt vaak genoemd als veroorzaker van RSI-klachten. Doel van het hier beschreven onderzoek was het bepalen van de invloed van knijpkracht en schouderbelasting op de bloedtoevoer naar de onderarm tijdens een intermitterende knijptaak. Tijdens de knijptaak en de daaropvolgende herstelperiode werd...

Little is known about the involvement of cytokines in the pathogenesis of primary progressive (PP) multiple sclerosis (MS). We evaluated in this cross-sectional study whether IL-18, IL-12p35, IL-12p40, TNF-α, IFN-γ, IL-10, IL-4, TGF-β, IL-12Rβ1, and IL-12Rβ2 mRNA expression in unstimulated white blood cells showed significant differences between...

Two full-length lipoxygenase cDNA sequences (LoxB and LoxC) from barley (Hordeum distichum cv. L. Triumph) are described. The cDNAs share high homology with the barley LoxA cDNA. Southern blotting experiments indicate single copy numbers of the three lipoxygenase genes. RFLP mapping revealed the presence of single lipoxygenase loci. LoxA and...

A full length cDNA sequence for a barley grain lipoxygenase was obtained. It includes a 5' untranslated region of 69 nucleotides, an open reading frame of 2586 nucleotides encoding a protein of 862 amino acid residues and a 3' untranslated region of 142 nucleotides. The molecular mass of the encoded polypeptide was calculated to be 96.392. Its...
