STUDY DESIGN: A prospective study. OBJECTIVE: To identify factors potentially influencing patient self-evaluation of chronic low back pain (CLBP) and their interactions. SUMMARY OF BACKGROUND DATA: The impact of the time, context, and/or recall on the self-assessment of chronic pain intensity remains poorly understood. METHODS: A prospective study investigated patients' CLBP intensity over 29 days. Patients were evaluated on days 1 and 29 by the investigator with a pain intensity visual analog scale (0-100), and interviewed by phone on days 8, 15, and 22 to 28 to evaluate pain intensity with a numerical rating scale (0-10), either thrice daily (time-associated group), or during rest/activities (activity-associated group). Current and/or recalled pain intensities were also assessed. Means of recorded pain intensity and overall assessment of patient's pain intensity of the day were subjected to statistical analyses with analysis of variance and test of correlation. RESULTS: Among the 203 patients included, 194 (56.2% women; mean age: 47.5 +/- 12.1 year) were considered in the analysis (9 patients were not followed until day 24). Strong correlations were obtained between mean pain intensity (time-associated group = 44 patients) and overall assessment of pain intensity of the day. Strong correlations were also obtained between overall assessment of pain intensity of the day and intensity measured during each activity, but not between current pain intensity and remembered pain 24 of 48 hours earlier (activity-associated group = 150 patients). Recalled pain intensities for the last 7 or 28 days were strongly correlated with current pain intensity, but the correlations were markedly weaker after adjustment for day 29-pain intensity. CONCLUSION: For CLBP patients, overall assessment of pain intensity of the day at evening is accurate to assess pain on 1 day. Overall assessment of pain intensity of the day is very close with usual pain. Furthermore, 24 and 48 hours remembered pain intensity are not accurate measures. Recalls of pain on the 7 or 28 last days were very dependant of the pain intensity of the day of the assessment. These findings could contribute to improving pain intensity assessment in CLBP patients avoiding multiple assessments, especially during clinical trials. [less ▲]

By creating a solid lubricant thickness on both bearing races, a cage material of cryogenic ball bearing plays a significant role in the good dynamical behavior of the cage. This role is essential because of the lack of conventional lubricant into this kind of bearing. In this paper, a method able to identify if a particular potential cage material can correctly fulfill its function is described. In other words, if it can lead to a stable movement of the cage. From the identification of fundamental tribological parameters governing the cage behavior, this method presents an example of ranking of such materials. This is based on pin-on-disk tests and on a numerical approach. [less ▲]

The aim of this study was to evaluate the effect of two breeds (Belgian Blue vs. Limousin) and previous storage time in vacuum conditions on color and lipid stability of meat packaged in high-oxygen atmosphere. Limousin meat samples of this study presented a higher sensitivity to myoglobin and lipid oxidation than Belgian Blue samples. The higher content of fat in those samples was one of the factors that could explain this higher sensitivity. Lipid oxidation and myoglobin oxidation appear to be linked, and further studies to understand the interaction between both processes are still needed. An understanding of the oxidative processes and their interaction would provide a basis for explaining quality deterioration in meat and also for developing strategies (e.g. antioxidant supplementation) to maintain sensory qualities.

The present study includes researches regarding which method of extraction, maceration or ultrasounds, offer a richer aroma profile to apple vinegar. The aroma compounds were extracted from Ocimum basilicum L., a widely used herb in folk medicine and diets, for it’s flavoring and preserving activity. The aroma profile of the flavored vinegar was analyzed using a gas chromatograph coupled with a mass spectrometer Schimadzu, QP-2010 and through an AT-5 capillary column. Although both methods of extraction used dry herbs, differences in the aroma profile of the flavored apple vinegar were noticed. The apple vinegar that was flavored by ultrasounds, had higher concentrations of 1-Butanol-3-metil-acetat and p-Allyl-Anisol, a compound known for it’s toxic actions. The high concentration of 1-Butanol-2-metil-acetat, Eucalyptol and Linalool acetate, made us conclude/decide that, using maceration, as method of extraction, the fingerprint of the apple vinegar is richer and it’s medical virtues are higher.

Introduction: The treatment of choice for tendinopathies is eccentric reeducation. Although the clinical results appear favourable, the biomechanical changes to the tissue are not yet clear. Materiel and methods: This study compared the effects of two methods of training (eccentric (E) training and concentric (C) training) with untrained (U) rats. The animals underwent training over a period of five weeks. The tricipital, patellar and Achilles tendons were subsequently removed to perform a traction test to the point of tendon rupture, and a histological analysis was performed. Results: There was a significant improvement in the rupture force of the patellar and tricipital tendons between the U and E groups. The tricipital tendons in the control group presented a significantly smaller cross-section than the E- and C-trained groups. No significant difference was observed for the constraints between the three groups for all three tendons. However, a tendency towards improvement was observed between the trained and the U groups for the patellar tendon. Histological studies demonstrated the development of a greater number of blood vessels and a larger quantity of collagen in the eccentric group. Discussion and conclusion: The mechanical properties of tendons in rats improve after specific training, especially following eccentric training. [less ▲]

OBJECTIVES: The veneering process of frameworks induces residual stresses and can initiate cracks when combined with functional stresses. The stress distribution within the veneering ceramic as a function of depth is a key factor influencing failure by chipping. This is a well-known problem with Yttria-tetragonal-zirconia-polycrystal based fixed partial dentures. The objective of this study is to investigate the influence of veneer thickness on the stress profile in zirconia- and metal-based structures. METHODS: The hole-drilling method, often used for engineering measurements, was adapted for use with veneering ceramic. The stress profile was measured in bilayered disc samples of 20mm diameter, with a 1mm thick zirconia or metal framework. Different veneering ceramic thicknesses were performed: 1mm, 1.5mm, 2mm, 2.5mm and 3mm. RESULTS: All samples exhibited the same type of stress vs. depth profile, starting with compressive at the ceramic surface, decreasing with depth up to 0.5-1.0mm from the surface, and then becoming compressive again near the framework, except for the 1.5mm-veneered zirconia samples which exhibited interior tensile stresses. Stresses in the surface of metal samples were not influenced by veneer thickness. Variation of interior stresses at 1.2mm from the surface in function of veneer thickness was inverted for metal and zirconia samples. SIGNIFICANCE: Veneer thickness influences in an opposite way the residual stress profile in metal- and in zirconia-based structures. A three-step approach and the hypothesis of the crystalline transformation are discussed to explain the less favorable residual stress development in zirconia samples. [less ▲]

Verbal descriptions of unfamiliar faces have been found to impair later identification of these faces in adults, a phenomenon known as the “verbal overshadowing effect (VO)” (Schooler & Englster-Schooler, 1990). In spite of a large body of literature on the suggestibility of children testimony, only one study has examined whether descriptions also impaired children’s identification abilities in a single group of children (8-9 years old) and no evidence of VO was found (Memon & Rose, 2002). However, the method might not have been appropriate to observe this effect as the description and the control tasks were not completed immediately but after a 24h delay that has sometimes been associated to a release of the VO effect (e.g. Schooler & Englster-Schooler, 1990; Finger & Pezdek, 1999). The aim of this experiment was to examine the influence of verbal descriptions and delay on face identification in several groups of children (7-8, 10-11, 13-14 years old) and adults when assigned either to “No delay”, “Post description delay” or “Post encoding delay” condition. The quality and influence of descriptors across the ages were also examined. [less ▲]
