La haute couture a généralement été cernée dans les rapports qu'elle entretient avec les opérations de "griffe" propres à la haute culture, dans l'esprit de l'article fondateur réservé à cette question par Pierre Bourdieu et Yvette Delsaut ("Le couturier et sa griffe : contribution à une théorie de la magie", Actes de la recherche, 1975). L'examen d'un corpus de nécrologies de grands couturiers dans Paris Match montre que la haute couture se trouve aujourd'hui de plus en plus indexée du côté de la culture de masse sous l'impulsion de facteurs internes à son propre secteur de production (allant dans le sens d'une certaine fabrication standardisée) et externes (relevant d'une logique people appliquée aux représentants les plus médiatisés du secteur).

In this paper we trace some of the key points in the history of Science and Technology Studies (STS). In particular we outline the inherently political dynamics of the field. Against We underline two emerging patterns in the curse of STS: the one of “depoliticisation” and the one of increasing “engagement”. We address the case study nanotechnologies and discuss their intertwined history with the STS. This allows us to point at the risk that the increasing institutionalisation of STS and the political mandate that frames and stabilizes the field’s relationship to the technological developments would create a political void. We conclude that STS research is at a crossroads. It is facing an important empirical turn, which may deprive it from its political significance, and constantly redefine its institutional constraints. STS has to continuously question its underlying political assumptions (as it occurs more and more regarding public participation) and to make it explicit. [less ▲]

Injuries to the anterior cruciate ligament (ACL) of the knee are disabling, often associated with other intra-articular damages and increase the risk of early onset of osteoarthritis. It is very probable that multiple risk factors act in combination to influence injury risk. It is important to have a comprehensive understanding of these ACL risk factors, whose neuromuscular factors, even if investigations on neuromuscular factors reported to date do not provide a complete understanding of ACL injury risk. According to several recent studies, the neuromuscular control of joint biomechanics during a specific activity seems to represent a predicting factor of an ACL injury, by quantifying the intersegmental forces and moments generated about the tibio-femoral joint. Laboratory studies have shown that landing from a jump performs cutting and pivoting maneuvers with less knee and hip flexion, increases knee valgus and internal rotation of the hip coupled, with increased external rotation of the tibia and quadriceps muscle activation (especially in women). It has been hypothesized that these movement patterns increase the strain in the ACL during activity and that the large difference in knee injury incidence rates between males and females (1/4.5) may be attributed to neuromuscular differences and resultant mechanics. Although studies have shown that the position of the knee and the magnitude and sequence of muscle contraction can increase ACL strain values, it is hard to exactly correlate these movements to what occurs during activity and sport and at the time of ACL injury. Recently, a simpler assessment tool has been validated and is able to be administered in a clinic-based testing environment Consequently, the screening for ACL injury risk could be performed on a more widespread population. Athletes who went on to a primary ACL injury also demonstrated significant side to side differences in lower extremity biomechanics as well as reduced relative lower extremity flexor activation relative to an uninjured control population during the vertical drop jump. Similar mechanisms of injury risk have been identified in athletes medically cleared to return to sport after ACL reconstruction. These seminal findings indicate that these abnormal and asymmetrical biomechanical and neuromuscular control profiles are likely both residual to, and exacerbated by, the initial injury. A study revealed that a fatigue-induced protocol altered the latency as well as the magnitude of reflex responses of the hamstring muscles and the tibial translation only in women. The authors of various studies have suggested that the hamstring muscles play an important role in maintaining knee stability and that they protect the ACL during movements of the tibia relative to the femur. Therefore, decreased reflex responses of the hamstring muscles and in turn an increased the tibial translation might contribute to the pathomechanics of the ACL injuries. It is therefore conceivable that the fatigue-induced decrease of the hamstring neuromuscular function may increase the tibial translation and probably contributes to the higher incidence of ACL injuries, especially in women. A preventive approach to decrease ACL injuries could integrate muscle imbalances as a risk factor. If it has been scientifically validated than the muscle strength profile determined by an isokinetic testing offers a predictive value on the hamstring lesion occurrence, similar studies have not permitted such a conclusion about ACL injury. The isokinetic assessments after ACL reconstruction have allowed us to observe, on the healthy contralateral knee, a higher frequency of reduced hamstring/quadriceps ratios. A possible pre-existing weakness in the hamstring and the occurrence of an ACL injury is therefore possible but only a difficult prospective approach due to the multifactorial nature of ligament injuries could clarify that point. In conclusion, a functional analysis of the landing of a jump and an isokinetic muscle strength assessment have been suggested to represent predictive elements of an ACL rupture, but further studies are needed to have a stronger evidence of their predictive qualities of injury.

Glycohaemoglobin, and particularly haemoglobin A1c(HbA1c), assays have been used for many years to retrospectively evaluate the glycaemic control of diabetic patients. Cut-off values have been established for deciding treatment modifications. The techniques used in the laboratories however exhibit varying quality, and all of them are not yet standardized. The consequence is an under-utilization of this test, especially in non-hospital practice. In this context, working groups of Société Française de Biologie Clinique (SFBC), Association de Langue Française pour l'Etude du Diabète et des Maladies Métaboliques (ALFEDIAM) and Société Française d'Endocrinologie (SFE) have met together, in order to analyze the national status, and to propose practical recommendations for implementing a standardization process on the basis of international experiences. It is recommended to exclusively express results as HbA1c percentage, using methods standardized and certified by comparison to reference methods such as those using Diabetes Control and Complications Trial (DCCT) values. Simultaneously, contacts have been established with manufacturers, and the realisation of periodic quality control surveys was encouraged. [less ▲]

Introduction : Nationwide studies are mandatory to assess changes in the epidemiology of HBV infection in Europe. Aim : To describe epidemiological characteristics of HBsAgpositive patients, especially inactive carriers, and to evaluate how practitioners manage HBV patients in real life. Methods : Belgian physicians were asked to report all chronically infected HBV patients during a one-year period. Results : Among 1,456 patients included, 1,035 (71%) were classified into one of four phases of chronic infection : immune tolerance (n = 10), HBeAg-positive hepatitis (n = 248), HBeAgnegative hepatitis (n = 420) and inactive carrier state (n = 357 HBeAg-negative patients with ALT < upper limit of normal (ULN) and HBV DNA < 2,000 IU/mL). Using less restrictive criteria for ALT (1-2 ULN) or HBV DNA (2,000-20,000 IU/mL), 93 unclassified patients were added to the group of inactive carriers. These 93 additional inactive carriers were younger, more frequently males, with similar risk factors for HBV infection and histological features compared to inactive carriers according to recent guidelines. Recent guidelines on management of HBV patients were generally followed, but systematic HBV DNA measurements and HDV coinfection screening should be reinforced. Conclusion : In Belgium, an inactive carrier state was a common form of chronic HBV infection. Using less restrictive criteria for classification of inactive carriers did not modify their main characteristics and seemed better adapted to clinical practice. Recent guidelines on management of HBV patients should be reinforced. [less ▲]

The human T-cell leukemia virus type I (HTLV-I)-encoded Tax protein activates transcription from the viral promoter via association with the cellular basic leucine zipper factor cAMP-response element-binding protein-2. Tax is also able to induce cellular transformation of T lymphocytes probably by modulating transcriptional activity of cellular factors, including nuclear factor-kappaB, E2F, activator protein-1 (AP-1), and p53. Recently, we characterized in HTLV-I-infected cells the presence of a novel viral protein, HBZ, encoded by the complementary strand of the HTLV-I RNA genome (Gaudray, G., Gachon, F., Basbous, J., Biard-Piechaczyk, M., Devaux, C., and Mesnard, J.-M. (2002) J. Virol. 76, 12813-12822). HBZ is a nuclear basic leucine zipper protein that down-regulates Tax-dependent viral transcription by inhibiting the binding of cAMP-response element-binding protein-2 to the HTLV-I promoter. In searching for other cellular targets of HBZ, we identified two members of the Jun family, JunB and c-Jun. Co-immunoprecipitation and cellular colocalization confirmed that HBZ interacts in vivo with JunB and c-Jun. When transiently introduced into CEM cells with a reporter gene containing the AP-1 site from the collagenase promoter, HBZ suppressed transactivation by c-Jun. On the other hand, the combination of HBZ with Jun-B had higher transcriptional activity than JunB alone. Consistent with the structure of its basic domain, we demonstrate that HBZ decreases the DNA-binding activity of c-Jun and JunB. Last, we show that c-Jun is no longer capable of activating the basal expression of the HTLV-I promoter in the presence of HBZ in vivo. Our results support the hypothesis that HBZ could be a negative modulator of the Tax effect by controlling Tax expression at the transcriptional level and by attenuating activation of AP-1 by Tax.

A certain possible approach for the control of HCCI chemistry is to use kinetic chemistry mechanisms. This opens a field of interest that lead to the composition of a validated reduced PRF chemistry mechanism. For this purpose a skeletal chemical reaction mechanism for n-heptane and for iso-octane are constructed from a detailed n-heptane and iso-octane mechanism of the Chalmers University of Technology. Subsequently these two mechanisms are forged into one reduced chemical reaction mechanism for mixtures of n-heptane and isooctane (39 species and 47 reactions). This mechanism is numerically validated against the Chalmers mechanisms, respecting the HCCI application range. The reduced mechanism is also successfully numerically validated against another more detailed mechanism provided by LLNL. Engine experiments are performed validating this mixture mechanism with respect to the fuel composition containing n-heptane and iso-octane. The influence of the compression ratio and the equivalence ratio is also studied and used to validate the reduced PRF mechanism. [less ▲]
