Abstract
Introduction: To identify high risk alleles for gallstone disease, we analyzed association of LDLR AvaII, LRPAP1 insertion/deletion, CETP TaqI B, and LPL HindIII polymorphisms with gallstone disease. Methods: In DNA samples of 214 gallstone patients and 322 age and sex matched controls, specific region containing polymorphisms was PCR amplified and digested with restriction enzymes except for LRPAP1 insertion/deletion polymorphism. Results: LRPAP1 gene insertion/deletion polymorphism was found to be significantly associated with gallstone disease. Genotype 11 was conferring significant risk for gallstone disease in females only (P = 0.019; OR 2.577, 95% CI 1.144-5.806). LDLR AvaII, CETP TaqI B, and LPL HindIII polymorphisms were not found to be associated with gallstone disease either at genotype or allele level. Conclusions: LRPAP1, II genotype carrier females may have increased risk for gallstone disease. On the other hand, LDLR AvaII, CETP TaqI B, and LPL HindIII polymorphisms may not be associated with gallstone disease. (c) 2006 Elsevier Ireland Ltd. All rights reserved.

Abstract
In this study we compared the proteomes of macrophages and heterophils isolated from the spleen 4 days after intravenous infection of chickens with Salmonella Enteritidis. Heterophils were characterized by expression of MMP9, MRP126, LECT2, CATHL1, CATHL2, CATHL3, LYG2, LYZ and RSFR. Macrophages specifically expressed receptor proteins, e. g. MRC1L, LRP1, LGALS1, LRPAP1 and a DMBT1L. Following infection, heterophils decreased ALB and FN1, and released MMP9 to enable their translocation to the site of infection. In addition, the endoplasmic reticulum proteins increased in heterophils which resulted in the release of granular proteins. Since transcription of genes encoding granular proteins did not decrease, these genes remained continuously transcribed and translated even after initial degranulation. Macrophages increased amounts of fatty acid elongation pathway proteins, lysosomal and phagosomal proteins. Macrophages were less responsive to acute infection than heterophils and an increase in proteins like CATHL1, CATHL2, RSFR, LECT2 and GAL1 in the absence of any change in their expression at RNA level could even be explained by capturing these proteins from the external environment into which these could have been released by heterophils.
