Inflammation has long been recognised as notoriously difficult to measure both in clinical practice and in the laboratory. Of all the cardinal features of inflammation, pain relief is really what the patients want, and among disabled persons, rheumatic patients are the only ones who must cope with chronic pain. The rheumatologist, however, is also interested in other parameters that are thought to reflect improvement of the inflammatory process. The methods used to clinically assess rheumatoid arthritis (RA) should share the following four parameters: validity, sensitivity, reliability and simplicity. Unfortunately, at present, no single ideal method is capable of accurately reflecting disease activity in RA. The measurement of pain relief by the visual analogue scale, the determination of the Ritchie index and the duration of morning stiffness, plus patient assessment of global response should be enough to detect clinical activity of the drug in RA. If we are working with slow-acting drugs or so-called disease modifying antirheumatic drugs (DMARDs), it should be appropriate to include X-ray analysis and laboratory tests in the evaluation. A reduction in the number of fresh erosions and/or the healing of present erosions can give reliable information on the capacity of the drug to really modify the course of the disease. At present, measurement of the erythrocyte sedimentation rate and of acute phase serum proteins seems to offer the best available assessment during early weeks of therapy. The other biological tests are of limited value in reflecting or predicting a beneficial clinical response to DMARDs. [less ▲]

This paper addresses the issues linked to simulation failures during integration in finite-volume flow models, especially those involving a two-phase state. This kind of model is particularly useful when modeling 1D heat exchangers or piping, e.g., in thermodynamic cycles involving a phase change. Issues, such as chattering or stiff systems, can lead to low simulation speed, instabilities and simulation failures. In the particular case of two-phase flow models, they are usually linked to a discontinuity in the density derivative between the liquid and two-phase zones. In this work, several methods to tackle numerical problems are developed, described, implemented and compared. In addition, methods available in the literature are also implemented and compared to the proposed approaches. Results suggest that the robustness of the models can be significantly increased with these different methods, at the price of a small increase of the error in the mass and energy balances. [less ▲]

Small-conductance Ca(2+)-activated K(+) channels (SK channels) underlie the prolonged postspike afterhyperpolarization (AHP) observed in many central neurons and play an important role in modulating neuronal activity. However, a lack of specific and reversible blockers of these channels hampers their study in various experimental conditions. Because previous work has shown that bicuculline salts block these channels, we examined whether related alkaloids, namely laudanosine quaternary derivatives, would produce similar effects. Intracellular recordings were performed on rat midbrain dopaminergic neurons and hippocampus CA1 pyramidal cells. Binding experiments were performed on rat cerebral cortex membranes. Laudanosine, methyl-laudanosine, and ethyl-laudanosine blocked the apamin-sensitive AHP of dopaminergic neurons with mean IC(50) values of 152, 15, and 47 microM, respectively. The benzyl and butyl derivatives were less potent. Methyl-laudanosine had no effect on the I(h) current, action potential parameters, or membrane resistance of dopaminergic cells, or on the decrease in input resistance induced by muscimol, indicating a lack of antagonism at GABA(A) receptors. Interestingly, 100 microM methyl-laudanosine induced a significant increase in spiking frequency of dopaminergic neurons but not of CA1 pyramidal cells, suggesting the possibility of regional selectivity. Binding experiments on laudanosine derivatives were in good agreement with electrophysiological data. Moreover, methyl-laudanosine has no affinity for voltage-gated potassium channels, and its affinity for SK channels (IC(50) 4 microM) is superior to its affinity for muscarinic (IC(50) 114 microM) and neuronal nicotinic (IC(50) > or =367 microM) receptors. Methyl-laudanosine may be a valuable pharmacological tool to investigate the role of SK channels in various experimental models. [less ▲]

Leukemias/lymphomas with IGH-involving del(14q)(1) commonly lose the DLK1-GTL2 imprinted domain that comprises several paternally and maternally expressed genes, including a cluster of microRNAs. Given that deletion of this region could lead to inactivation of a monoallelically expressed tumor suppressor gene, our study aimed at determination of the parental origin of del(14q/IGH). The designed allele-specific methylation study of the DLK1/GTL2 intergenic differentially methylated region allowed us to determine the parental origin of del(14q/IGH) in 9/20 analyzed cases. In six cases del(14q/IGH) was of the paternal origin and in three cases of the maternal origin. These findings argue against the concept that a TSG/anti-oncomir located in the imprinted region is systematically inactivated by a targeted deletion of its functional allele. [less ▲]

Methylmercury (MeHg) bioaccumulates along the food web, leading to the highest levels in tissues of predatory species. It constitutes the predominant form present in the blood of marine mammals. The blood cells, including the immune cells, are therefore exposed to the toxic properties of that chemical. Nevertheless, selenium (Se) is an essential element absorbed concomitantly to MeHg which seems to modulate this toxicity. The goal of this study is to evaluate the immunotoxicity of MeHg on the harbor seal (Phoca vitulina) T lymphocytes, highly important in the adaptive immune response, and to investigate the modulating effect of Se on that toxicity. In parallel, the concentrations of MeHg, total mercury (T-Hg) and Se are determined in free-ranging harbour seal blood in order to follow their contamination levels. The T lymphocytes were isolated from the whole blood, exposed to various MeHg and Se concentrations and the exposure effects were estimated by functional tests including the evaluation of viability, proliferation, metabolic activity, DNA and protein synthesis, and by morphological analysis by transmission electron microscopy. The mean T-Hg concentration was 172 ± 143 µg/l of whole blood. The T lymphocytes cultures in vitro displayed a decreasing number of viable cells with increasing concentrations of MeHg, and numerous ultrastructural defects. The cells exposed to MeHg notably displayed distortion of the plasmic membrane, nucleus fragmentations, chromatin compaction, swelling mitochondrias and cytoplasmic vacuolisations. Those results highlighted various immunotoxic effects of MeHg, both at the functional and ultrastructural levels. The antagonistic role of Se on MeHg immunotoxicity is discussed. [less ▲]
