Intestinal enteroendocrine cells (IECs) secrete gut peptides in response to both nutrients and non-nutrients. Glucose and amino acids both stimulate gut peptide secretion. Our hypothesis was that the facilitative glucose transporter, GLUT2, could act as a glucose sensor and the calcium-sensing receptor, CasR, could detect amino acids in the intestine to(More)
Ticks secrete a cement cone composed of many salivary proteins, some of which are rich in the amino acid glycine in order to attach to their hosts' skin. Glycine-rich proteins (GRPs) are a large family of heterogeneous proteins that have different functions and features; noteworthy are their adhesive and tensile characteristics. These properties may be(More)
In teleost fish, the head kidney, thymus, and spleen are generally regarded as important immune organs. In this study, the ontogeny of these organs was studied in Atlantic halibut (Hippoglossus hippoglossus), larvae at various stages of development. We observed that the kidney was present at hatching, the thymus at 33days post hatch (dph), while the spleen(More)
We report here the identification and an initial characterization of a novel cell cycle-regulated molecule, SCC-112. SCC-112 cDNA (6744 bp) encodes a longest open reading frame (ORF) comprised of 1297 amino acids, representing a approximately 150-kDa nuclear protein. SCC-112 mRNA and protein levels were relatively high during the G2/M phase of the cell(More)
Intranasal drug delivery is known to overcome the blood-brain barrier (BBB) for delivery of drugs to brain. The objective of this study was to prepare risperidone (RSP)-loaded solid lipid nanoparticles (RSLNs) and explore the possibility of brain targeting by nose-to-brain delivery. RSLNs were prepared by solvent emulsification-solvent evaporation method(More)
OBJECTIVES To evaluate the relationships between selected sociodemographic factors and the use of particular types of complementary and alternative medicine (CAM) in the general U.S. population. CAMs make up a heterogeneous group of practices. Although it is well established that sociodemographic factors impact the use of conventional medicine, it is(More)
As known from mammalia, the co-receptors CD4 or CD8 associate with a lymphocyte cell-specific kinase (Lck) upon T-cell activation. Lck phosphorylates tyrosine residues within the CD3 chains, providing docking sites for a 70 kDa zeta-associated-protein (ZAP-70), a tyrosine protein kinase important for T-cell signaling. The sequences of a CD4-like gene(More)
Reassociation kinetics and flow cytometry data indicate that ixodid tick genomes are large, relative to most arthropods, containing>or=10(9) base pairs. The molecular basis for this is unknown. We have identified a novel small interspersed element with features of a tRNA-derived SINE, designated Ruka, in genomic sequences of Rhipicephalus appendiculatus and(More)
Genes encoding the five Atlantic halibut (Hippoglossus hippoglossus L.) cytokines; interleukin (IL)-1β, IL-6, IL-11b, IL-12βc, and interferon (IFN) γ, were cloned and characterised at a molecular level. The genomic organisation of the halibut cytokine genes was similar to that seen in mammals and/or other fish species. Several mRNA instability motifs were(More)
Nodaviruses encode an RNA-dependent RNA polymerase called Protein A that is responsible for replication of the viral RNA segments. The intracellular localization of Protein A from a betanodavirus isolated from Atlantic halibut (AHNV) was studied in infected fish cells and in transfected mammalian cells expressing Myc-tagged wild type Protein A and mutants.(More)
