Complex regional pain syndrome (CRPS) remains difficult to understand and to treat. The definition criteria of the IASP (International Association for the Study of Pain) in 1994 showed an overestimation of diagnosis. A revision of these criteria conducted in Budapest in 2003 permits to ameliorate the specificity of these criteria in clinical and research settings. Pathophysiology is poorly understood, only one mechanism can’t explain the observed manifestations in the CRPS: facilitated neurogenic inflammation, peripheral and central abnormalities of the central nervous system … Finally, the different laboratory tests are reviewed. Unfortunately, no laboratory test is the signature of CRPS. The diagnosis relies on history and rigorous clinical examination. Imagery method, neurophysiologic test and evaluation of inflammatory parameters help to the differential diagnosis. [less ▲]

The large proportion of sandy soils of Thua Thien Hue, in Central Vietnam, present a particular habitat for soil-inhabiting organisms among which earthworms represent close to 70% of total biomass. This study identified relationships between the characteristics of soil and earthworms. Our inventories yielded the presence of seven species of earthworms belonging to the families Glossoscolecidae, Megascolecidae and Microchaetidae. These were: Pontoscolex corethrurus, Glyphidrilus papillatus, Pheretima rodericensis, Pheretima danangana, Pheretima sp., Perionyx excavatus, and Lampito mauritii. Those of the Microchaetidae were present in acid soils with a high rate of silt and clay. Species in the other families were associated with poor but less acid sandy soils. This study also showed that the number of P. corethrurus was significantly higher in orchards while L. mauritii was significantly more common in soils with cultures other than rice. The species G. papillatus was significantly more abundant in fallow and was the only species found in this habitat. Highest earthworm diversity (Shannon-Wiener index(H=0.97)) was found in crops like manioc and sweat potatoes rather than in rice. [less ▲]

BACKGROUND: Activation and coagulation biomarkers were measured within the Strategies for Management of Antiretroviral Therapy (SMART) trial. Their associations with opportunistic disease (OD) in human immunodeficiency virus (HIV)-positive patients were examined. METHODS: Inflammatory (high-sensitivity C-reactive protein [hsCRP], interleukin-6 [IL-6], amyloid-A, and amyloid-P) and coagulation (D-dimer and prothrombin-fragment 1+2) markers were determined. Conditional logistic regression analyses were used to assess associations between these biomarkers and risk of OD. RESULTS: The 91 patients who developed an OD were matched to 182 control subjects. Patients with an hsCRP level > or =5 microg/mL at baseline had a 3.5 higher odds of OD (95% confidence interval [CI], 1.5-8.1) than did those with an hsCRP level <1 microg/mL (P=.003, by test for trend) and patients with an IL-6 level > or =3 pg/mL at baseline had a 2.4 higher odds of OD (95% CI, 1.0-5.4) than did those with an IL-6 level <1.5 pg/mL (P=.02, by test for trend). No other baseline biomarkers predicted development of an OD. Latest follow-up hsCRP level for those with an hsCRP level > or =5 microg/mL (compared with a level <1 microg/mL; odds ratio [OR], 7.6; 95% CI, 2.0-28.5; [P=.002, by test for trend), latest amyloid-A level for those with an amyloid-A level > or =6 mg/L (compared with a level <2 mg/L; OR, 3.8; 95% CI, 1.1-13.4; P=.03, by test for trend), and latest IL-6 level for those with an IL-6 level > or =3 pg/mL (compared with a level <1.5 pg/mL; OR 2.4; 95% CI, 0.7-8.8; P=.04, by test for trend) were also associated with development of an OD. CONCLUSIONS: Higher IL-6 and hsCRP levels independently predicted development of OD. These biomarkers could provide additional prognostic information for predicting the risk of OD. [less ▲]

Humans are a diurnal species usually exposed to light while engaged in cognitive tasks. Light not only guides performance on these tasks through vision but also exerts non-visual effects that are mediated in part by recently discovered retinal ganglion cells maximally sensitive to blue light. We review recent neuroimaging studies which demonstrate that the wavelength, duration and intensity of light exposure modulate brain responses to (non-visual) cognitive tasks. These responses to light are initially observed in alertness-related subcortical structures (hypothalamus, brainstem, thalamus) and limbic areas (amygdala and hippocampus), followed by modulations of activity in cortical areas, which can ultimately affect behaviour. Light emerges as an important modulator of brain function and cognition. [less ▲]

This paper discusses the integrated design of mechatronic systems with varying dynamics, such as serial and parallel machine tools. This characteristic affects the machine stability and performance. A computer-aided integrated design methodology is proposed and validated on a pick-and-place robot. It consists of two main steps: (i) the derivation of reduced models from a flexible multibody model and (ii) the systematic robust control design. Eventually, the integrated design of the system, considering both structural and control parameters, can be performed. [less ▲]

Clownfishes are aggressive fishes that use sound production to defend their anemone territory. It has been shown that they produce agonistic sounds using a jaw teeth snapping. At present, this mechanism has highlighted the onset of the sound but has not explained yet which structure is responsible for the sound modulation. Interestingly, some acoustic features such as dominant frequency and pulse duration are directly related to fish size. Such variations are linked to a morphological constraint. Also, the existent relationship between fish size and swimbladder size implies that the swimbladder might be involved in the sound production. Sound analyses in Amphiprion clarkii showed that the experimental filling of the swimbladder with physiological liquid (NaCl 9‰) significantly modified the acoustic features. The most striking changes were a significant increase in dominant frequency and a significant decrease in pulse duration. These observations highlighted the implication of the swimbladder in sound modulation. In clownfishes, dominant frequency and pulse duration are morphologically determined signals. The swimbladder appears to modulate these acoustic features by acting as a resonant chamber. [less ▲]

The solar photospheric abundance of ruthenium is revised on the basis of a new set of oscillator strengths derived for Ru I transitions with wavelengths in the spectral range 2250–4710 Å. The new abundance value (in the usual logarithmic scale where the solar hydrogen abundance is equal to 12.00), ARu = 1.72 ± 0.10, is in agreement with the most recent meteoritic result, ARu = 1.76 ± 0.03. The accuracy of the transition probabilities, obtained using a relativistic Hartree–Fock model including core-polarization effects, has been assessed by comparing the theoretical lifetimes with previous experimental results. A comparison is also made with new measurements performed in this work by the time-resolved laser-induced fluorescence spectroscopy for 10 highly excited odd-parity levels of Ru I [less ▲]

The effect of high-flux hemodialysis membranes on patient survival has not been unequivocally determined. In this prospective, randomized clinical trial, we enrolled 738 incident hemodialysis patients, stratified them by serum albumin 4 and 4 g/dl, and assigned them to either low-flux or high-flux membranes. We followed patients for 3 to 7.5 yr. Kaplan-Meier survival analysis showed no significant difference between high-flux and low-flux membranes, and a Cox proportional hazards model concurred. Patients with serum albumin 4 g/dl had significantly higher survival rates in the high-flux group compared with the low-flux group (P 0.032). In addition, a secondary analysis revealed that high-flux membranes may significantly improve survival of patients with diabetes. Among those with serum albumin 4 g/dl, slightly different effects among patients with and without diabetes suggested a potential interaction between diabetes status and low serum albumin in the reduction of risk conferred by high-flux membranes. In summary, we did not detect a significant survival benefit with either high-flux or low-flux membranes in the population overall, but the use of high-flux membranes conferred a significant survival benefit among patients with serum albumin 4 g/dl. The apparent survival benefit among patients who have diabetes and are treated with high-flux membranes requires confirmation given the post hoc nature of our analysis. [less ▲]
