BACKGROUND Therapeutic strategies for the prophylaxis of IgE-mediated allergy remain an unmet medical need. Cell therapy is an emerging approach with high potential for preventing and treating immunological diseases. We aimed to develop a cell-based therapy inducing permanent allergen-specific immunological tolerance for preventing IgE-mediated allergy. METHODS Wild-type mice were treated wit...

BACKGROUND Group 5 allergens are small proteins that consist of two domains. They belong to the most potent respiratory allergens. OBJECTIVE To determine the binding sites and to study allergic patients' IgE recognition of the group 5 allergen (Phl p 5) from timothy grass pollen using human monoclonal IgE antibodies that have been isolated from grass pollen allergic patients. METHODS Using ...

The research, development practitioner, and donor community has begun to focus on food loss and waste - often referred to as post-harvest losses (PHL) - in Sub-Saharan Africa. This article reviews the current state of the literature on PHL mitigation. First, we identify explicitly the varied objectives underlying efforts to reduce PHL levels. Second, we summarize the estimated magnitudes of los...

Primary hepatic peripheral T-cell lymphoma (PHL) is extremely rare. A case of primary hepatic peripheral T-cell lymphoma of a 59-year-old male is presented in the current study. PHL lesions are diagnosed by the existence of a hepatic mass, in the absence of lymphadenopathy, splenomegaly or bone marrow involvement associated with normal tumor markers. Treatment options are surgical resection and...

The grass pollen allergen, Phl p 7, belongs to a family of highly cross-reactive calcium-binding pollen allergens. Because Phl p 7 contains most of the disease-eliciting epitopes of pollen-derived calcium-binding allergens, hypoallergenic variants were engineered according to the x-ray crystal structure of Phl p 7 for allergy vaccination. In three recombinant variants, amino acids essential for...

Separation and structural characterization of lignin are essential for valueadded utilization of hemicelluloses and lignin in the prehydrolysis liquor (PHL) of a kraft-based Whangee (a genus of bamboo) dissolving pulp production. In this work, lignin in the PHL was separated by acidification treatment (AT) and rotary vacuum evaporation treatment (RVET), and the separated crude lignin was then c...

Bu araştırma ‘Vanda’ kiraz çeşidinin fidan gelişimi üzerine PHL-A, Gisela 5 ve Colt anaçlarının etkisini belirlenmek amacıyla yürütülmüştür. Anaçların çeşidinde etkisi önemli bulunmuştur (p<0.05). Genel olarak, gelişim PHL-A benzer olmuştur. Anaçlara bağlı boyu 125.7 (Gisela 5)-198.8 cm (Colt), kalem gövde çapı 12.8 5)-22.4 mm yan dal sayısı 1.1 (PHL-A)-9.9 sürgün uzunluğu 21.53 5)-42.63...

The antibiotics phenazine-1-carboxylic acid (PCA) and 2,4-diacetylphloroglucinol (Phl) are major determinants of biological control of soilborne plant pathogens by various strains of fluorescent Pseudomonas spp. In this study, we described primers and probes that enable specific and efficient detection of a wide variety of fluorescent Pseudomonas strains that produce various phenazine antibioti...

Dendritic cells (DCs) are sentinels of the immune system for antigen recognition and uptake, as well as presentation to naïve T cells for stimulation or priming. Internalization and endocytic degradation of allergens by DCs are important steps required for T cell priming. In the current study we investigated binding and internalization of purified recombinant non-glycosylated grass pollen aller...

High performance anion-exchange chromatography with pulse amperometric detector (HPAEC-PAD) is a reliable method to systematically determine the sugar contents in pulp and paper waste streams, including bleaching and extraction liquors. We used the same method to determine the sugar content of industrially produced pre-hydrolysis liquor (PHL) from a kraft-based dissolving pulp production proces...
