To understand the basis of pathogenesis by Legionella longbeachae serogroup 1, the importance of the Mip protein in this species was examined. Amino-terminal analysis of the purified, cloned L. longbeachae serogroup 1 ATCC 33462 Mip protein confirmed that the cloned gene protein was expressed and processed in an Escherichia coli background. DNA sequence analysis of plasmid pIMVS27, containing t...

We discovered a new cataract mutation, kfrs4, in the Kyoto Fancy Rat Stock (KFRS) background. Within 1 month of birth, all kfrs4/kfrs4 homozygotes developed cataracts, with severe opacity in the nuclei of the lens. In contrast, no opacity was observed in the kfrs4/+ heterozygotes. We continued to observe these rats until they reached 1 year of age and found that cataractogenesis did not occur i...

The main intrinsic polypeptide (MIP) is the major protein present in the lens fiber cell membrane and is the product of a gene which, as far as is known, is expressed only in the lens. We have used in situ hybridization and immunofluorescence microscopy to characterize the expression of this gene during the course of development in the rat. At progressive stages of lens morphogenesis, we find t...

background :     river and underground waters are main sources of tap water in guilan, iran. overland wastes move into rivers during periods of heavy or extended rain that is very common in the area. pseudomonas aeruginosa , legionella pneumophila , and escherichia coli are main human pathogens with water source. this study is designed to determine the load of these bacteria in main water suppl...

results stereoscopic displays of the nerves were obtained in all 24 elbows by vr, mip, and fiber tractography post-processing methods. the vr/mip post-processing methods were easier to perform compared to fiber tractography. there was no significant difference among the scores of fiber tracking and vr/mip reconstruction for single direction. the imaging quality scores of fiber tractography and ...

BACKGROUND Interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) are key mediators of the intracapsular pathological conditions of the temporomandibular joint (TMJ). Therefore, the gene expression profiles in synovial fibroblast-like cells (SFCs) from patients with internal derangement of the TMJ were examined after they were stimulated with IL-1β or TNF-α to determine which genes were alt...

Understanding the evolutionary and genomic mechanisms responsible for turning the soil-derived saprophytic mycobacteria into lethal intracellular pathogens is a critical step towards the development of strategies for the control of mycobacterial diseases. In this context, Mycobacterium indicus pranii (MIP) is of specific interest because of its unique immunological and evolutionary significance...

Nuclear factor kappa B (NF-kappa B) is a transcription factor that regulates expression of several genes coding for inflammatory and immunoregulatory proteins including the neutrophil chemotactic cytokine MIP-2. In previous studies we found that crocidolite asbestos activates the nuclear translocation of NF-kappa B as well as MIP-2 gene expression in rat alveolar type II cells. Here we report t...

Chemokines regulate the host immune response to a variety of infectious pathogens. Since the role of chemokines in regulating host immunity in children with Plasmodium falciparum malaria has not previously been reported, circulating levels of beta-chemokines (MIP-1alpha, MIP-1beta, and RANTES) and their respective transcriptional profiles in ex vivo peripheral blood mononuclear cells (PBMCs) we...

BACKGROUND Pathological aspects of atherosclerosis are well described, but gene profiles during atherosclerotic plaque progression are largely unidentified. METHODS AND RESULTS Microarray analysis was performed on mRNA of aortic arches of ApoE-/- mice fed normal chow (NC group) or Western-type diet (WD group) for 3, 4.5, and 6 months. Of 10 176 reporters, 387 were differentially (>2x) express...
