In the two Higgs doublet model, there is the possibility that the vacuum where the universe resides in is metastable. We present the tree-level bounds on the scalar potential parameters which have to be obeyed to prevent that situation. Analytical expressions for those bounds are shown for the most used potential, that with a softly broken Z 2 symmetry. The impact of those bounds on the model’s phenomenology is discussed in detail, as well as the importance of the current LHC results in determining whether the vacuum we live in is or is not stable. We demonstrate how the vacuum stability bounds can be obtained for the most generic CP-conserving potential, and provide a simple method to implement them. [less ▲]

Auroral spectra have been obtained in the 3380- to 3560-A region to study the forbidden N I 4S-2P doublet at 3466 A. The forbidden N I 3466 A/N2 Vegard-Kaplan ratio is found to remain constant. This is in agreement with the results of a model calculation showing that the dominant source of N(2P) atoms is dissociative excitation of N2 by fast electrons, and the major quenching agent is atomic oxygen. A value of about 5 x 10 to the 9th/cu cm sec is deduced for the ratio of the N(2P) quantum yield to the atomic oxygen deactivation coefficient. [less ▲]

Introduction: Peri-tonsillar abscess remains one of the most frequent serous complications of oropharyngeal or dental infections. It can evolve to parapharyngeal and/or retropharyngeal spaces. It can be life-threatning and, more rarely, neurological complications are described. Observations: We report the case of a 56 year old woman who developed within few days a progressive tetraparesia due to cervical medullary compression. This compression was consecutive to an epidurite which was a complication of a retropharyngeal abscess. The only surgical act was a cervicotomy to drain the abscess and identify the pathological germ. A targeted antibiotherapy was quickly begun. The recovery was obtained rather quickly and the neurological evolution was good. After one year, the cervical spine presents a post-infectious deformation without sign of root or spinal-cord compression. Conclusion: A cervical tetraparesia induced by spondylodiscitis and epiduritis following a retropharyngeal abscess with Staphylococcus aureus is a rare complication. Adequate diagnosis, as fast as possible, is mandatory in order to carry out an adapted antibiotherapy in the hopes of a complete recovery. The place of surgery on the spine remains to be specified.

A case of carcinomatous monoarthritis involving the left knee due to colonic adenocarcinoma is described. Large recurrent synovial effusion, that will be later hematic, lytic lesion of the bones and chondrolysis were noted. Knee positron emitting tomography scan using FDG (FDG-PET) revealed a diffuse increased uptake in soft tissues assumed to be synovium, the hypertrophy of which was identified by ultrasonography. Whole body PET scan showed extensive lymph node, visceral and bone metastases, suggesting that the increase in the synovium could also be of metastatic origin. The final diagnosis of synovial carcinomatosis secondary to the known colonic adenocarcinoma was confirmed by histological analysis of biopsies obtained by arthroscopy. A review of the literature is realised. To our knowledge, this is the first synovial metastasis studied by FDG-PET. [less ▲]

We report a rare case of single cervical metas- tasis of breast cancer. Bone metastases are the most frequent in breast cancer. early diagnosis combined with the new the- rapeutic advances have considerably improved the quality of life and increased the survival. imaging plays a great role in the diagnosis, particularly scintigraphy and radiography, but sometimes also ct and Mri. the treatment is currently not standardized and it combines hormone therapy, chemotherapy, radiotherapy, and / or surgery.

A case of malignant carotid body tumor with nodal, hepatic and bone metastases is reported. Carotid body chemodectomas are slow-growing tumors which invade local structures. These tumors are usually benign but can occasionally produce local and distant metastases. Development of metastatic localizations is the only formal proof of malignancy as histology cannot distinguish between benign and malignant chemodectomas. Bilateral carotid arteriography gives the diagnosis. Surgery is the basis of treatment and should be performed early in the course to limit operative complications. Radiotherapy can be given as adjuvant treatment. [less ▲]

By focusing on recent developments on natural and non-natural azasugars (iminocyclitols), this review bolsters the case for the role of olefin metathesis reactions (RCM, CM) as key transformations in the multistep syntheses of pyrrolidine-, piperidine-and azepane-based iminocyclitols, as important therapeutic agents against a range of common diseases and as tools for studying metabolic disorders. Considerable improvements brought about by introduction of one or more metathesis steps are outlined, with emphasis on the exquisite steric control and atom-economical outcome of the overall process. The comparative performance of several established metathesis catalysts is also highlighted. [less ▲]

Avec l’émergence des nouvelles technologies, on observe une consommation croissante de métaux rares et en particulier des terres rares. Celle-ci a engendré un déséquilibre croissant de l’offre et la demande, déséquilibre accentué par le rôle des acteurs et notamment de la Chine. Les métaux rares sont ainsi devenus des enjeux politiques et stratégiques. En outre, les impacts environnementaux de ces exploitations sont de plus en plus dénoncés ce qui introduit de nouvelles contraintes pour les entreprises. Devant la complexité de la problématique, il n’y a pas de solution miracle mais quelques pistes qui toutes indiquent l’impérieuse nécessité d’une modification profonde des comportements collectifs et individuels car le modèle de développement actuel n’est pas durable.

Meteor spectroscopy provides both quantitative data on the excitation conditions in the meteor plasma, the progressive ablation of mineral species in the meteoroid, and the meteoroid's elemental abundances for selected elements. The recent NASA and USAF sponsored Leonid Multi-Instrument Aircraft Campaign provided high-resolution spectra of relatively faint meteors using a slit-less cooled CCD spectrograph. Additional observations from ground and space extended the wavelength range from 250 to 1050 nm. We have measured excitation conditions in the meteor plasma from studies of meteoric air plasma emissions (N_2, N, O, O_2) and ablated metal atom line emissions (Fe). Results were compared to laboratory calibrated air plasma emission models and LTE models of metal atom line emissions. Further insight was provided by a spectrum recorded serendipitously at the European Southern Observatory VLT telescope, which provides the first spectral information over a cross-section of a meteor trail. We also searched for emissions from CN, H, and OH that may be ablation products of organic matter and mineral water contained in the meteoroid. We will present an overview of the information gathered to date and discuss the meteoric metal atom abundances (Fe, Mg, Si, Na, Ca, Mn, Al, Ni, Ti, Sc, Cr, Co, and V) measured for representative meteoroids.
