Serotonin neuron transplants exacerbate L-DOPA-induced dyskinesias in a rat model of Parkinson's disease

Clinical trials in patients with Parkinson's disease have shown that transplants of fetal mesencephalic dopamine neurons can form a new functional innervation of the host striatum, but the clinical benefits have been highly variable: some patients have shown substantial recovery in motor function, whereas others have shown no improvement and even a worsening in the 3,4-dihydroxyphenyl-L-alanine (L

A structure of persuasion in Galatians: Epistolary and rhetorical appeal in an aural setting

The purpose of this paper is to ponder the reception of the Letter to the Galatians in an aural setting. How did the first recipients react, what can we expect that they remembered after having listened to the letter? Are there structural elements in the letter that would have aided the aural reception of the letter? In four readings, the investigation traces textual indicators of interaction and

Orionid Meteor Stream

Based on data available at the IAU (International Astronomical Union) Meteor Data Center in Lund 60 precisely reduced photographic Orionid orbits and 17 video observed orbits are analysed. Mean photographic and video orbits are compared with the orbit of comet Halley. The Orionid meteoroid stream structure and radiant motion is studied, and compared with previous visual and photographic studies of

Prevention of autoimmunity by targeting a distinct, noninvariant CD1d-reactive T cell population reactive to sulfatide

Class I and class II MHC-restricted T cells specific for proteins present in myelin have been shown to be involved in autoimmunity in the central nervous system (CNS). It is not yet known whether CD1d-restricted T cells reactive to myelin-derived lipids are present in the CNS and might be targeted to influence the course of autoimmune demyelination. Using specific glycohpid-CD1d tetramers and clon

Loss of C/EBP alpha cell cycle control increases myeloid progenitor proliferation and transforms the neutrophil granulocyte lineage

CCAAT/enhancer binding protein (C/EBP)alpha is a myeloid-specific transcription factor that couples lineage commitment to terminal differentiation and cell cycle arrest, and is found mutated in 9% of patients who have acute myeloid leukemia (AML). We previously showed that mutations which dissociate the ability of C/EBP alpha to block cell cycle progression through E2F inhibition from its function

Civilreligion med ett mänskligt ansikte : president Václav Havels tankar om individ, religion och samhälle

In this thesis civil religion in the Czech Republic is studied throught the way it is expressed in the speeches of president Václav Havel. Earlier studies on civil religion have shown how civil religiion can be a latent phenomenon that is activated in times of societal change and crisis. In Havel's speeches, this is expressed by the emphasis put on democratic values, such as basic human rights, an

Essential role for CD103 in the T cell-mediated regulation of experimental colitis

The integrin CD103 is highly expressed at mucosal sites, but its role in mucosal immune regulation remains poorly understood. We have analyzed the functional role of CD103 in intestinal immune regulation using the T cell transfer model of colitis. Our results show no mandatory role for CD103 expression on T cells for either the development or CD4(+)CD25(+) regulatory T (T reg) cell-mediated contro

Dynorphin B is present in sensory and parasympathetic nerves innervating pial arteries

Dynorphin B (dyn B) in trigeminal ganglion cells and in perivascular nerve fibers in pial arteries was demonstrated in rat, guinea-pig, and monkey by immunohistochemistry. The pathway from the trigeminal ganglion, which runs via the nasociliary nerve and ethmoidal foramen to the pial arteries, was shown in rat by retrograde tracer technique and nerve section. In the guinea-pig the peptide was demo

IL-3 and IL-4 activate cyclic nucleotide phosphodiesterases 3 (PDE3) and 4 (PDE4) by different mechanisms in FDCP2 myeloid cells

In FDCP2 myeloid cells, IL-4 activated cyclic nucleotide phosphodiesterases PDE3 and PDE4, whereas IL-3, granulocyte-macrophage CSF (GM-CSF), and phorbol ester (PMA) selectively activated PDE4. IL-4 (not IL-3 or GM-CSF) induced tyrosine phosphorylation of insulin-receptor substrate-2 (IRS-2) and its association with phosphatidylinositol 3-kinase (PI3-K). TNF-alpha, AG-490 (Janus kinase inhibitor),

Transiently binding antibody fragments against Lewis x and sialyl-Lewis x

Biomolecular recognition is often characterised by low affinity where many weak interactions work either alone or in concert, resulting in an inherent dynamic situation. For example the well-studied weak binding of cell-cell interactions is predominantly based on a range of carbohydrates that interact with numerous (protein) ligands. Finding appropriate binders to these carbohydrate structures may

Antigen-specific beta-chemokine production and CD8(+) T-cell noncytotoxic antiviral activity in HIV-2-infected individuals

Human immunodeficiency virus-2 (HIV-2) is less pathogenic than HIV-1, and the disease progression in HIV-2-infected individuals seems to be similar to that seen in HIV-1-infected long-term nonprogressors. Cell-mediated immune responses and the production of noncytotoxic CD8(+) T-cell antiviral factors (CAF) and beta-chemokines have been correlated to protection against HIV-1 and associated with as

Formulation and in vitro/in vivo evaluation of combining DNA repair and immune enhancing nutritional supplements

Combining nutritional supplements to achieve synergistic benefit is a common practice in the nutraceutical industry. However, establishing. added health benefit from a combination of natural ingredients is often assumed, untested and without regard to the principle of metabolic competition between the active components. Here, we report on the combination of a cat's claw water extract (C-Med-100, c

Rats and mice immunised with chimeric human/mouse proteinase 3 produce autoantibodies to mouse Pr3 and rat granulocytes

Aim: In this study, we employed chimeric human/ mouse Proteinase 3 ( PR3) proteins as tools to induce an autoantibody response to PR3 in rats and mice. Method: Rats and mice were immunised with recombinant human PR3 ( HPR3), recombinant murine PR3 ( mPR3), single chimeric human/ mouse PR3 ( HHm, HmH, mHH, mmH, mHm, Hmm) or pools of chimeric proteins. Antibodies to mPR3 and HPR3 were measured by EL

Spectroscopic and dynamic properties of the peridinin lowest singlet excited states

Spectroscopic properties as well as excited state dynamics of the carotenoid peridinin in several solvents of different polarities were investigated by time-resolved fluorescence and transient absorption techniques. A strong dependence of the peridinin lowest excited states dynamics on solvent polarity was observed after excitation into the strongly allowed S-2 state. Peridinin relaxes to the grou

Phase behavior of an ionic surfactant with mixed monovalent/polymeric counterions

A "complex salt" of cetyltrimethylammonium (CTA(+)) with short (30 repeating units) polyacrylate (PA(-)) counterions has been synthesized. The phase diagrams of its aqueous mixtures with either the surfactant cetyltrimethylammonium acetate (CTAAc), or the polyelectrolyte NaPA, have been studied by visual inspection through crossed polarizers and by small-angle X-ray scattering. Both of the ternary

Advanced intercross line mapping of Eae5 reveals Ncf-1 and CLDN4 as candidate genes for experimental autoimmune encephalomyelitis

Eae5 in rats was originally identified in two F-2 intercrosses, (DA x BN) and (E3 X DA), displaying linkage to CNS inflammation and disease severity in experimental autoimmune encephalomyelitis (EAE), respectively. This region overlaps with an arthritis locus, Pia4, which was also identified in the (E3 X DA) cross. Two congenic strains, BN.DA-Eae5 and BN.DA-Eae5.R1, encompassing the previously des

Pozzolanic Interaction between Portland Cement and Silica Fume in Concrete.

This article outlines an experimental and numerical study of the long-term interaction between silica fume and Portland cement in concrete subjected to air, water or sealed curing. For this purpose about 2000 kg of eight qualities of concrete were studied at 4 different ages each over a period of 90 months. Half of the concretes contained silica fume. Parallel studies of strength, hydration and in
