Is there specific educational curriculum to information literacy? Which training for our teachers and information professionals? Proving interest of Infomration literacy programs for our students? How to create a critical attitude in information retrieval? So many questions and others animate the EduDOC group's and led us to observe in detail the IL training activities organized in Belgium. This communication is not intended to answer these questions but rather to generate more questions [less ▲]

Traceability is a major concern in food industry. Genetic markers such as single nucleotide polymorphisms (SNPs) can be used in the genetic traceability context. Two loci rich in SNPs were sequenced in 96 different individuals. Thirty-two significant SNPs were observed. All tested individuals presented a different genotype. In order to simplify the procedure, a hybrid amplicon joining the two regions of interest was generated. A traceability experiment based on this strategy was successfully performed allowing to identify the right couple « ear-meat ». [less ▲]

Major challenge for semi-solid processing includes broadening the range of alloys that can be successfully thixoformed and developing alloys specifically for thixoforming. One important parameter is appropriate solidus-liquidus interval. The wider the solidification interval, the wider the processing window. This study is related to the experimental determination of this critical parameter on eight different steel compositions. This parameter was obtained using Differential Scanning Calorimetry. This technique allows to obtain the solid fraction versus temperature. The paper also presents the results of thermophysical properties determination such as thermal diffusivity, heat capacity and thermal conductivity. These properties were measured from room temperature to semi-solid state in one particular steel. The thermal diffusivity was measured using the Laser Flash method and the heat capacity using a DSC calorimeter. The thermal conductivity was obtained by calculation knowing the thermal dilatation measured with a dilatometer. All these measurements were performed for temperatures up to the liquidus. These parameters are difficult to measure but they are important to determine for the conductive heating phase of a semi-solid forming (SSM) process. [less ▲]

We produced and analyzed mice deficient for Na/Ca exchanger 3 (NCX3), a protein that mediates cellular Ca(2+) efflux (forward mode) or Ca(2+) influx (reverse mode) and thus controls intracellular Ca(2+) concentration. NCX3-deficient mice (Ncx3(-/-)) present a skeletal muscle fiber necrosis and a defective neuromuscular transmission, reflecting the absence of NCX3 in the sarcolemma of the muscle fibers and at the neuromuscular junction. The defective neuromuscular transmission is characterized by the presence of electromyographic abnormalities, including low compound muscle action potential amplitude, a decremental response at low-frequency nerve stimulation, an incremental response, and a prominent postexercise facilitation at high-frequency nerve stimulation, as well as neuromuscular blocks. The analysis of quantal transmitter release in Ncx3(-/-) neuromuscular junctions revealed an important facilitation superimposed on the depression of synaptic responses and an elevated delayed release during high-frequency nerve stimulation. It is suggested that Ca(2+) entering nerve terminals is cleared relatively slowly in the absence of NCX3, thereby enhancing residual Ca(2+) and evoked and delayed quantal transmitter release during repetitive nerve stimulation. Our findings indicate that NCX3 plays an important role in vivo in the control of Ca(2+) concentrations in the skeletal muscle fibers and at the neuromuscular junction [less ▲]

The aims of this study were (1) to correlate cough and body temperature (BT) with the severity of bronchopneumonia in pigs, (2) to determine whether these clinical signs can be used to early diagnose bronchopneumonia and (3) to assess the predictive values of cough and BT regarding lung lesions. Bronchopneumonia was induced by administering E. coli endotoxin (LPS) combined with Pasteurella multocida type A (PmA) in the trachea of 13 piglets. Saline-instilled negative controls (n = 8), PmA inoculated (n = 6) and LPS instilled (n = 5) groups were also constituted. Cough and BT were recorded daily while the bronchopneumonia severity was assessed using bronchoalveolar lavage fluid (BALF) cytology, cytokines and measurement of lung lesion volume. Changes in expiratory breathing pattern were also measured (Penh). The combination of LPS and PmA induced a subacute bronchopneumonia characterised by macrophage, neutrophil, and lymphocyte infiltration, changes in Penh and an increase in the mRNA level of IFN-gamma while IL8, IL-18 and TNF-alpha mRNA levels remained unchanged. The daily body weight gain of infected animals was significantly reduced. Cough and BT changes were proportional to the intensity of the lung inflammatory process, functional respiratory changes and to the extent of macroscopic lesions. When comparing the individual values of cough and BT to thresholds defined for both parameters, an early diagnosis of pneumonia was possible. Considering the pooled data of each group, it was possible to define thresholds allowing an early segregation between the groups of diseased and healthy piglets. The daily values of cough and BT were predictive for the volume of lung lesions recorded at the end of the trial. In conclusion, cough and BT appear as potential indicators for the intensity and the evolution of the respiratory disease. They also seem to be good predictors for the magnitude of lung lesions and weight gain recorded at the study endpoint. [less ▲]

This synthesis aims to review the pulmonary function tests available in swine. Two techniques are used in order to measure the variations of the mechanical properties of the respiratory system. The oesophageal balloon remains the most used technique in order to determine these properties in pigs. However, it requires a systematic anaesthesia of the animal. The impulse oscillometry specifically measures the mechanical properties of the respiratory system, by a non invasive way, but the animals have to be trained to be immobilized or sedated to perform the measurement. The whole body arometric plethysmography allows measuring the respiratory pattern in unsedated freely moving piglets. That method allows investigating pigs for long term studies while minimizing the stress related to handling. From this point of view, it represents the less stressing technique for pigs. Finally, blood gases analysis is the easiest method to use in the field. It permits to assess respiratory function by measuring pH and blood partial pressures in oxygen and carbon dioxide [less ▲]

Investigating factors associated with muscle strains highlight the multifactorial origin of the injury and the difficulty of identifying isolated or combined factors that caused the injury. Among the numerous causes reported in the literature, only a few have been scientifically associated with injury occurrence, while others have been empirically suggested. Contradictions in articles dealing with muscle strength and imbalance are frequent, and are probably the result of differences in methodology and criteria for patient inclusion. Imbalance in muscle strength commonly refers to abnormal bilateral asymmetry (between homologous groups) and a disruption of the agonist-antagonist ratio. Some authors who focus on a history of hamstring or adductor strains have demonstrated the frequent abnormality of muscle strength and balance by means of isokinetic assessment. Mixed ratios, combining the eccentric performance of “decelerating” muscles (such as the hamstrings) and the concentric performance of “mobiliser” muscles (such as the quadriceps) are suggested and seem relevant. An increased emphasis on eccentric strengthening exercises, particularly for the hamstrings, and ratio correction on the basis of statistically selected cut-offs, significantly reduces the recurrence rate of the injury and lingering complaints upon return-to-sport. Similarly, isokinetic interventions, as a preseason screening tool in sports where there is a high rate of muscle strain injuries, could detect imbalances early and thus promote a preventive strategy.

Slightly after the emergence some 400 millions years ago of the first signs of adaptive immune response, tolerogenic pathways developed in order to preserve the integrity of self from potential autoimmune toxicity. Amongst those tolerogenic pathways, the thymus occupies a central place both by deleting self-reactive T cells that are produced in the thymus during random recombination of gene segments encoding the variable parts of the T-cell receptor for antigen (TCR) (negative selection), and by generating self-antigen specific regulatory T cells (Tr). A repertoire of neuroendocrine-related genes are transcribed by thymic stromal cells — epithelial and ‘nurse’ cells (TEC/TNC), dendritic cells (DC) and macrophages (MF) — in such a way that a dominant protein precursor is expressed in the thymus environment. Oxytocin (OT) and neurokinin A (NKA) are the dominant thymic precursors for the neurohypophysial hormone and tachykinin families, respectively. With regard to the insulin gene family, all members are transcribed following a precise cell topography and hierarchy in the profile of gene expression: IGF2 (TEC/TNC) > IGF1 (MF) >> INS (medullary TEC and/or DC). This hierarchy implies that IGF-2 is more tolerated than IGF-1, and much more than Insulin (Ins). The low level of INS transcription in the thymus also explains why Ins displays immunogenic properties, as well as the significant prevalence (±40%) of anti-Ins autoantibodies in the general population. Ins administration failed in providing tolerance or protection toward islet ß cells in type 1 diabetes (T1D). In contrast, the presentation of IGF-2 B11-25, the homologous sequence of Ins B9-23, to peripheral blood mononuclear cells (PBMC) isolated from DQ8+ T1D adolescents significantly increases IL-10 secretion and IL10 expression. Given the potent regulatory/suppressive properties of IL-10 on the autoimmune response toward islet ß cells, these data support that IGF-2 derived sequences constitute a strong basis for the development of an antigen-specific driven tolerogenic approach for T1D prevention and/or cure.
