Primary hepatic lymphoma (PHL) is confined to the liver with no evidence of lymphomatous involvement in other lymphoid structures. It is a very rare malignancy representing less than 1 % of all extra nodal lymphomas. The exact cause of PHL is unknown, but it seems that there is a strong association between hepatitis C virus (HCV) and PHL. The majority of PHL patients are middle-aged men who usu...

BACKGROUND Grass pollen is one of the most important allergen sources. The aim of this study was to compare the in vivo allergenic activity of two recently characterized major grass pollen allergens, Phl p 4 and Phl p 13, with three established major grass pollen allergens, Phl p 1, Phl p 2 and Phl p 5 as a basis for the formulation of a grass pollen allergy vaccine based on purified allergens....

Polcalcins are small EF-hand proteins believed to assist in regulating pollen-tube growth. Phl p 7, from timothy grass (Phleum pratense), crystallizes as a domain-swapped dimer at low pH. This study describes the solution structures of the recombinant protein in buffered saline at pH 6.0, containing either 5.0 mM EDTA, 5.0 mM Mg(2+), or 100 μM Ca(2+). Phl p 7 is monomeric in all three ligation ...

BACKGROUND Knowledge of allergen-specific T cell epitopes is a prerequisite not only for therapeutic approaches but also for elucidating immunological mechanisms of type I allergy. Ex vivo detection of allergen-specific T cells using class II tetramer technology has become an important tool for investigating immune responses in atopic and healthy individuals. METHODS Using (3)H-thymidine inco...

UNLABELLED BACKGROUND Grass pollen is a major cause of respiratory allergy worldwide and contain a number of allergens, some of theme (Phl p 1, Phl p 2, Phl p 5, and Phl 6 from Phleum pratense, and their homologous in other grasses) are known as major allergens. The administration of grass pollen extracts by immunotherapy generally induces an initial rise in specific immunoglobulin E (sIgE) ...

Fluorescent Pseudomonas strains producing the antimicrobial secondary metabolite 2,4-diacetylphloroglucinol (Phl) play a prominent role in the biocontrol of plant diseases. A subset of Phl-producing fluorescent Pseudomonas strains, which can additionally synthesize the antimicrobial compound pyoluteorin (Plt), appears to cluster separately from other fluorescent Pseudomonas spp. based on 16S rR...

The crystal structure of poly(7-heptalactone) (PHL) is presented. PHL has been synthesized by a combination ring-opening polymerization η-heptalactone and reversible addition–fragmentation chain transfer using diphenyl phosphate as catalyst. noncommercial available monomer prepared oxidation cycloheptanone. determined analysis the X-ray powder diffraction profiles electron patterns single cryst...

On the basis of IgE epitope mapping data, we have produced three allergen fragments comprising aa 1-33, 1-57, and 31-110 of the major timothy grass pollen allergen Phl p 6 aa 1-110 by expression in Escherichia coli and chemical synthesis. Circular dichroism analysis showed that the purified fragments lack the typical alpha-helical fold of the complete allergen. Superposition of the sequences of...

OBJECTIVES The primary objective of this report was to describe the infrastructures and processes of selected European and North American pre-hospital fibrinolysis (PHL) programs. A secondary objective is to report the outcome data of the PHL programs surveyed. BACKGROUND Despite its benefit in reducing mortality in patients with ST-segment elevation myocardial infarction, PHL remained underu...

As effective probiotic Bacillus isolates that can increase BW gain (BWG) are identified, they may offer advantages in terms of stability, cost, and feed application over probiotics limited to drinking water application. Additionally, an effective direct-fed microbial (DFM) may offer an effective alternative to antibiotic growth promoters. Previously, 4 Bacillus isolates were identified and eval...
