A cheilitis is an inflammatory disease confined to the lips. Several origins are recognized. Their nature is often different in children and adults. Some are spongiotic due to irritation or allergic reaction. Other lesions are keratotic and can evolve to leucoplasia and epidermoid carcinoma. [less ▲]

Le 30 janvier 1594, l’archiduc Ernest, fils de Maximilien II, faisait sa joyeuse entrée à Bruxelles. Il venait en effet d’être nommé gouverneur général des Pays-Bas par son puissant parent, Philippe II. Son séjour aux Pays-Bas allait être de courte durée. Une maladie qui le minait dès avant son départ l’emporta dans la nuit du 20 au 21 février 1595. Personnalité politique de médiocre envergure, malhabile et velléitaire, Ernest apparut comme un fantoche entre les mains du monarque espagnol, ce qui lui valut d’être vilipendé avant de sombrer dans l’oubli. La collection de peintures qu’il constitua durant les derniers mois de sa vie passés aux Pays-Bas mérite pourtant qu’on s’y attarde. Certes de faible ampleur par rapport à celle de son frère, l’empereur Rodolphe II, elle se signalait par son excellent niveau qualitatif, réunissant des œuvres de Hubert Van Eyck, Rogier van der Weyden, Bosch, Floris, Mostaert, Grimmer et Lucas van Valckenborch. Mais sans conteste, c’est une suite des Mois de Bruegel qui en était le plus prestigieux joyau. Elle avait été offerte à l’archiduc par la Ville d’Anvers, lorsque celui-ci fit sa joyeuse entrée dans la cité scaldienne, le 5 juillet 1594. Il y a lieu de réévaluer la place que l’archiduc Ernest occupa dans le contexte du collectionnisme de la fin du XVIe siècle ; elle a été injustement occultée par un intérêt trop exclusivement centré sur Rodolphe II. Il convient notamment de déterminer les circonstances dans lesquelles Ernest de Habsbourg procéda à ses acquisitions, et de voir comment ses choix s’inscrivent dans l’histoire du goût, reflétant un jugement très sûr, ainsi qu'un vif intérêt pour les diverses tendances qu’illustrèrent les peintres des Pays-Bas dans la seconde moitié du XVIe siècle. Enfin, il importe de préciser quel fut le destin de ses collections. L’historique de la fameuse suite de Bruegel, en particulier, appelle maintes remarques. Il est très loin d’être aussi clair et solide qu’on s’est plu à l’affirmer jusqu’ici. [less ▲]

We explore large-scale nucleotide compositional fluctuations along the human genome through the optics of the wavelet transform mi- croscope. Analysis of the TA and GC skews reveals the existence of strand asymmetries associated to transcription and/or replication The investigation of 14854 intron-containing genes shows that both skews display a characteristic step-like profile exhibiting sharp tran- sitions between transcribed (finite bias) and non-transcribed (zero bias) regions. As we observe for 7 out of 9 origins of replica- tion experimentally identified so far, the (AT+GC) skew exhibits rather sharp upward jumps, with a linear decreasing profile in be- tween two successive jumps. We describe a multi-scale method- ology that allows us to predict 1012 replication origins in the 22 human autosomal chromosomes. We present a model of replica- tion with well-positioned replication origins and random termina- tion sites that accounts for the observed characteristic serrated skew profiles. We emphasize these putative replication initiation zones as regions where the chromatin fiber is likely to be more open so that DNA be easily accessible. In the crowded environment of the cell nucleus, these intrinsic decondensed structural defects actually predisposes the fiber to spontaneously form rosette-like structures that provide an attractive description of genome organization into replication foci that are observed in interphase mammalian nuclei.

We aimed to determine IgE-dependant skin sensitization rates to moulds, dermatophytes and yeasts in patients with typical allergic diseases in comparison to those with inflammatory dermatitis seen over the course of one year. Skin prick tests were done in 267 patients (172 women and 95 men; median age 38 years, range 25–50 years). We allocated them into 8 groups: 64 with head and neck atopic dermatitis; 11 with seborrheic dermatitis; 52 with eczema and not atopic dermatitis other than on the head and neck; 64 with rhinitis, conjunctivitis and asthma; 28 with urticaria; 10 with food allergy; and 12 healthy controls. Skin tests were done with the following aqueous standardized commercial extracts: Alternaria, Penicillium, Aspergillus, Cladosporium, Mucor, Trichophyton, Epidermophyton, Candida albicans, Malassezia and Saccharomyces cerevisiæ. Globally, positive skin test reactions occurred most frequently with the yeast extracts, less to the dermatophytes and even less to the moulds. The results were homogenous among members of each group. The relevance of our tests was reinforced by the fact that the moulds that gave positive skin tests most frequently were those most often isolated in the Belgian environment. In patients with atopic dermatitis of the head and neck, positive tests were most frequent with four moulds and three yeasts; compared to this group, positive tests were less frequent in patients with atopic dermatitis localized to other sites. In inflammatory dermatitis of the head and neck, the study of immediate hypersensitivity to yeasts seems to be important. [less ▲]

The urban mosquito Culex quinquefasciatus Say (Diptera: Culicidae) uses chemicals to locate suitable water pools for oviposition. These chemicals when identified can be used to trap gravid female mosquitoes. Experiments in Davis and in Sacramento (California, in the United States) were made to improve the trapping efficiency of Reiter/Cumming gravid traps baited by several attractants (or attractant blends). Unfortunately, it appeared that the number of gravid female mosquitoes collected was not sufficient to differentiate the efficacy of attractant blends tested by statistical analysis. However, a positive correlation between the total mosquito number collected daily and the highest humidity shows that the mosquito oviposition activity seems to be influenced by the humidity during the night. Observations on total number of mosquitoes and the highest temperature seem to reveal a threshold temperature which is critical for the adult mosquito survival. A coupled gas chromatography – electronantennography (GC-EAD) protocol was also developed step by step in order to find new Culex quinquefasciatus oviposition attractants. After obtaining repetitive electroantennographic (EA) response, two comparison experiments (SPME fiber type and infusion type) were made to finalize the specific GC-EAD/SPME protocol. This with the aim to prospect new attractants from fermented Bermuda grass infusion. Analyses based on all results permit to distinguish the EA responses from random perturbations (electromagnetic and vibration). GC-EAD/SPME of Bermuda grass infusion analyses confirms the presence of 10 and the activity of 9 chemical compounds as established by Du and Millar in 1999. Furthermore, experiments on Culex quinquefasciatus performed with the new protocol, brought to light the EA activity of 10 other unknown chemicals, 7 of which are low molecular weight chemical compounds. These new chemicals have now to be identified and their ability to elicit EA responses still has to be confirmed. [less ▲]

Les Pomacentridae constituent une des familles de l’ordre des Perciformes pour lesquels le comportement acoustique a déjà été avéré chez de nombreuses espèces. A l’heure actuelle, sept genres sont référencés comme étant des producteurs de sons : Amphiprion, Dascyllus, Stegastes, Chromis, Abudefduf, Plectroglyphidodon et Hemichromis. Les émissions sonores interviennent principalement dans la reproduction et la défense de territoire ; contribuant ainsi à la survie et au succès reproducteur des individus. Les Amphiprioninae, mieux connus sous le nom de poissons-clowns, créent de véritables clans familiaux au sein d’une même actinie autour de laquelle ils déterminent leur territoire. Ainsi, la production de sons semble jouer un rôle important dans leur comportement ; la structure sociale qui règne chez ces poissons impliquant le respect de la territorialité et de la hiérarchie, les émissions sonores pourraient notamment avoir comme rôle de maintenir une bonne cohésion au sein du groupe. Malgré plusieurs études réalisées sur la production de sons chez les Amphiprion, aucune explication satisfaisante du mécanisme producteur de sons n’a été développée, seules quelques hypothèses ont été formulées. Ce travail repose sur une approche biomécanique de la production de sons basée sur la réalisation de films aux rayons X à l’aide d’une caméra à haute vitesse, combinée à une étude de morphologie fonctionnelle. Le mécanisme sonore serait autre que ceux habituellement proposés (l’action de la vessie natatoire et le grincement des dents des mâchoires pharyngiennes). Il impliquerait la mise en mouvement de nombreuses structures squelettiques, notamment la dépression du plancher pharyngien ; ce dernier engendrerait alors la tension du ligament angulo-cératohyal dont la mise en vibration pourrait être à l’origine des émissions sonores [less ▲]

INTRODUCTION: The semicircular lipoatrophy of the thighs is a disorder whose incidence remained rare for years. Only recently, an "epidemic" situation emerged, affecting hundreds of subjects who shared a status of administrative employee. OBSERVATION: The older etiopathogenic hypotheses give way to a newer one implying the electromagnetic fields generated by computers and their wirings. The resulting modifications in the intrinsic bioelectrical properties of the skin could influence the biology of macrophages exhibiting lipophagic activity in the hypodermis. The electroactivation of these cells could lead to TNF-alpha release. DISCUSSION: The semicircular lipoatrophy of the thighs is a problem that may affect an employee out of two. Rather than hoping an efficaceous drug therapy, prevention must be advocated by adapting the work conditions related to the use of computerized devices. [less ▲]

This paper deals with the application of statistical process control techniques for damage diagnosis based on vibration measurements. The first approach considered in this work is based the Stochastic Subspace Identification (SSI) algorithm, from which a Kalman model is constructed to fit the measured response histories of the undamaged (reference) structure. This model may be used to make a prediction of the newly measured responses. The residual error between the model predictions and the actual measurements is defined as a damage-sensitive feature. Outlier statistics provides then a quantitative indicator of damage. The advantage of the method is that model extraction has to be performed only once using the reference data and that no further modal identification is needed. Thus on-line structural health monitoring may easily be realized. In the second approach, principal component analysis (PCA) of the sensor time-responses is used to extract principal directions (i.e. features), which define a subspace that is representative of the dynamics of the instrumented structure. Any change in the response of a single sensor affects the subspace spanned by the complete sensor response set. It follows that the subspace corresponding to the current state of the structure can be compared to the subspace of the initial state of the structure, assumed to be healthy, in order to diagnose possible damage. Principal component analysis may also be performed for every potential subset of damaged sensors in order to identify the involved sensor, and, therefore, the damaged substructure. [less ▲]

Epidemiologic studies have shown a clear comorbidity between migraine with aura and a patent foramen ovale (PFO). Under the age of 55, migraine with aura is a risk factor for ischemic stroke and a proportion of the latter is due to a PFO. It remains to be determined whether PFO is causally related to migraine attacks, or is a fortuitous association due to common genetic factors. Cortical spreading depression which is the underlying mechanism of the migrainous aura, could be favoured by a PFO. Several retrospective and uncontrolled studies suggest that percutaneous closure of a PFO for stroke or decompression illness in divers reduces frequency of migraine attacks with, but also without aura. Multicentric, prospective and controlled trials of this intervention in migraineurs are underway or in preparation. As long as their results are not known, there is no rationale for proposing PFO closure for migraine. [less ▲]

The kidney could be the cause of essential hypertension which can also cause renal disease. High blood pressure is also very common in chronic kidney disease, and is moreover a well-known risk factor for a faster progression of kidney failure. Hypertension and kidneys are thus closely linked. Hypertension must be aggressively treated in patients suffering from chronic kidney disease, with a blood pressure goal of less than 130/80 mmHg, even lower than 125/75 mmHg when proteinuria is over 1g/day, using optimal and effective antihypertensive drugs. Among them, the blockers of the renin-angiotensin axis offer nephroprotective but also cardioprotective properties beyond their effect on blood pressure. [less ▲]
