Evaluated the interaction of either gaboxadol HCl (THIP) or muscimol, both gamma-aminobutyric acid (GABA) type A agonists, with indirect-acting dopamine agonists (DAGs) methylphenidate, (+)-amphetamine, metamphetamine, amfonelic acid, indatraline, nomifensine, diclofensine, mazindol, and GBR 12935 and with direct-acting DAGs WIN 35,428, bupropion, GBR 12909, and cocaine. 1,832 male C57BL/6J mice were given either with saline or 1 of the doses of THIP or muscimol before an injection of a dopamine agonist. Gnawing on corrugated packing paper was measured. Results showed that: (1) indirect- but not direct-acting DAGs induced gnawing, (2) gnawing induced by indirect-acting DAGs GBR 12935, nomifensine and mazindol was potentiated in mice in which GABA type A receptors were stimulated either by THIP or muscimol, and (3) indirect DAGs had a differential sensitivity to the effects of THIP and muscimol.

BACKGROUND: Radiotracer and blue-dye lymphatic mapping is a recommended combined method to guide sentinel lymphadenectomy and full regional lymph node dissection in selected patients with cutaneous melanoma. OBJECTIVE: To evaluate the diagnostic accuracy and the prognostic value of gamma-probe-directed lymphatic mapping in cutaneous melanomas. METHODS: Sixty-five stage I and II melanoma patients underwent gamma-probe-directed lymphatic mapping. Sentinel lymph nodes were studied by both conventional and immunohistochemical stainings. The median follow-up was 11 months. RESULTS: Sensitivities of preoperative and intraoperative sentinel lymph node detection were 100 and 98%, respectively. Only 1 failure of detection and 1 missed same-basin metastasis were experienced in the axillary and cervical areas, respectively. Eleven patients (16.9%) had sentinel node metastases leading to adjuvant therapy. CONCLUSION: Gamma-probe-directed lymphatic mapping is useful for staging melanoma. However, in the expectation of a more specific identification of the sentinel lymph node, the standard protocol remains recommended for exploring the axillary and cervical areas. The histological examination supported in some cases by immunohistochemistry remains mandatory in all cases. [less ▲]

We present the results of Monte Carlo simulations of three-dimensional electromagnetic cascade initiated by interactions of the multi-TeV γ rays with the cosmological infrared/optical photon background in the intergalactic medium. Secondary electrons in the cascade are deflected by the intergalactic magnetic fields before they scatter on CMB photons. This leads to extended 0.1°-10° scale emission at multi-GeV and TeV energies around extragalactic sources of very high-energy γ rays. The morphology of the extended emission depends, in general, on the properties of magnetic fields in the intergalactic medium. Using Monte Carlo simulated data sets, we demonstrate that the decrease of the size of extended source with the increase of energy allows to measure weak magnetic fields with magnitudes in the range from ≤10[SUP]-16[/SUP]G to 10[SUP]-12[/SUP]G if they exist in the voids of the large scale structure.

La découverte d'une gammapathie monoclonale n'implique pas nécessairement le diagnostic de myélome multiple. Le myélome est une prolifération maligne d'un clone plasmocytaire dont l'évolution sans traitement est toujours fatale. Les traitements chimiothérapiques instaurés actuellement, tout en prolongeant la survie des patients, améliorent de façon nette la qualité de vie. En dehors de la greffe de moelle osseuse allogénique, la rémission complète n'est jamais synonyme de guérison. Récemment, l'interféron alpha 2 recombinant a complété positivement l'arsenal thérapeutique utilisé chez les malades souffrant de myéolme, de même que certains nouveaux protocoles chimiothérapiques.

The status of the axillary lymph nodes is one of the most important prognostic factors in women with early stage breast cancer. Histologic examination of removed lymph nodes is the most accurate method for assessing spread of disease to these nodes. Axillary lymph node dissection (ALND) remains the standard approach for women who have clinically palpable axillary nodes. The benefits of ALND include its impact on disease control (axillary recurrence and survival), its prognostic value, and its role in treatment selection. However, the anatomic disruption caused by ALND may result in lymphedema, nerve injury, and shoulder dysfunction, which compromise functionality and quality of life. For patients who have clinically negative axillary lymph nodes, sentinel lymph node (SLN) biopsy offers a less morbid method to determine if there are positive nodes, in which case axillary node dissection would be necessary. Patients who are SLN-positive should undergo complete ALND. Axillary reverse mapping (ARM) is a recent improvement of ALND which, like the biopsy of the GS, would reduce morbidity. [less ▲]

In this Report we present the Monte Carlo model for calculation of oxygen UV and IR emissions due to the electron precipitation in the Ganymede polar regions. These techniques will provide column densities of atmospheric species at better than or equal to 1 km spatial resolution, and will constrain the amount of some specific compounds from limb scans and during stellar occultation. This investigation also needs characterization of the vertical temperature profile from ground up to about 400 km altitude with ~5 km vertical resolution as well as mapping of water vapour concentration. This can be performed by multiple water line observations in the 200-600 μm wavelength range. It shall be complemented by ion and neutral mass spectrometry of plasma particles, radio occultations to measure structures of the neutral atmosphere and ionosphere, and plasma wave measurements to constrain plasma density and temperature of the ionosphere.

Recent events such as natural catastrophes (tsunami, hurricane, …) or terrorism attacks have highlighted the necessity of ensuring the structural integrity of buildings under exceptional events with the objective to save the life of the occupants and of the safety services (fireman, ambulance man, …) and also to avoid collateral damages to the adjoining buildings. The partial collapse of the Ronan Point Tower in 1968 in UK is considered as the starting point of the interest in the structural integrity of buildings but more recent catastrophes in the last decade such as the terrorist attack of the World Trade Center towers in 2001 or the earthquake/tsunami in Fukushima in 2011 have increased the interest of the engineering community and also of the population in this topic. According to different national and international design codes, the structural integrity of civil engineering structures should be ensured through appropriate measures but, in most of the cases, no precise practical guidelines on how to achieve this goal are provided. In the present report, some definitions are first given. Existing codes and standards are then reviewed and main conclusions are drawn on their adequacy to the present needs of practitioners. From this analysis, general and specific research needs within CIDECT are identified. These ones are detailed in two dedicated sections respectively on buildings and trusses. A summary table draws the main conclusions in terms of future required CIDECT investments. Finally some references to literature are listed. [less ▲]

The objective was to determine the interest and psychometric properties of a new QOL self-assessment questionnaire suitable for children 8–12 years old measuring alpha, beta and gamma changes: the ‘‘Inventaire Syste´mique de Qualite´ de vie pour Enfants’’ (ISQV-E ). This was a cross-sectional validation study. 288 children have completed the ISQV-E. Other tools were used: The ‘‘Autoquestionnaire de Qualite´ de Vie Enfants Image´’’ (AUQUEI), the State-Trait Anxiety Inventory for Children (STAIC), the Children’s Depression Inventory (CDI). The internal consistency of the four scores of the ISQV-E (state, goal, rank and gap) is satisfactory. All scores have their own specificity. The data show the convergent validity, sensitivity and applicability of the ISQV-E. On the other hand, no satisfactory factorial structure was found although a multidimensional theoretical perspective was applied. The feasibility of the ISQV-E seems clearly demonstrated and the value of this new tool seems evident in contexts of physical, psychological or social problems. The validation study was promising but certain points such as test–retest reliability remain to be studied. [less ▲]
