Traitement des sténoses sous-glottiques de l'enfant par résection crico-trachéale [Treatment of subglottis stenosis in children by cricotracheal resection].

Fifty-eight infants and children with a severe subglottic stenosis underwent a partial cricotracheal resection with primary thyrotracheal anastomosis. There were 2 grade II, 40 grade III, and 16 grade IV stenoses according to the Myer-Cotton classification. A 100% subglottic lumen was formed in 34 cases and a better than 80% lumen in 23 cases. Fifty-four of the 58 (93%) patients are presently decannulated; one patient sustained a complete restenosis and three patients with a better than 80% subglottic airway still await decannulation for the following reasons: severe tracheomalacia, bilateral cricoarytenoïd joint fixation and laryngeal malformation with fusion of the vocal cords in each case respectively. Forty-four patients have no exercise intolerance, 8 live fully normally but present a slight exertional dyspnea, one patient with a laryngeal malformation is decannulated but suffers from a severe exertional dyspnea, and 4 patients are still not decannulated. The voice is normal in 20 cases, a slight dysphonia is present in 17, a moderate to severe dysphonia in another 17 and 4 patients are still not decannulated.

A novel role for proline- and acid-rich basic region leucine zipper (PAR bZIP) proteins in the transcriptional regulation of a BH3-only proapoptotic gene.

Proline- and acid-rich (PAR) basic region leucine zipper (bZIP) proteins thyrotroph embryonic factor (TEF), D-site-binding protein (DBP), and hepatic leukemia factor have been involved in neurotransmitter homeostasis and amino acid metabolism. Here we demonstrate a novel role for these proteins in the transcriptional control of a BH3-only gene. PAR bZIP proteins are able to transactivate the promoter of bcl-gS. This promoter is particularly responsive to TEF activation and is silenced by NFIL3, a repressor that shares the consensus binding site with PAR bZIP proteins. Consistently, transfection of TEF induces the expression of endogenous bcl-gS in cancer cells, and this induction is independent of p53. A naturally occurring variant of DBP (tDBP), lacking the transactivation domain, has been identified and shown to impede the formation of active TEF dimers in a competitive manner and to reduce the TEF-dependent induction of bcl-gS. Of note, treatment of cancer cells with etoposide induces TEF activation and promotes the expression of bcl-gS. Furthermore, blockade of bcl-gS or TEF expression by a small interfering RNA strategy or transfection with tDBP significantly reduces the etoposide-mediated apoptotic cell death. These findings represent the first described role for PAR bZIP proteins in the regulation of a gene involved in the execution of apoptosis.

Le traitement religieux par les médias

Depuis le début de cette décennie, les médias accordent un intérêt croissant au religieux. Cet intérêt évolue en relation étroite avec le changement socioculturel qui affecte aussi bien le champ de la communication de masse que celui de la religion. On ne s'étonnera pas dès lors, explique l'A., d'observer que la mise en scène du religieux par les médias échappe, partiellement du moins, au contrôle des institutions religieuses, même les mieux organisées, et obéisse aux lois qui régulent leur langage.

Ablation of caterpillar labial salivary glands: technique for determining the role of saliva in insect-plant interactions.

There has been an ardent interest in herbivore saliva due to its roles in inducing plant defenses and its impact on herbivore fitness. Two techniques are described that inhibit the secretion of labial saliva from the caterpillar, Helicoverpa zea, during feeding. The methods rely on cauterizing the caterpillar's spinneret, the principal secretory structure of the labial glands, or surgically removing the labial salivary gland. Both methods successfully inhibit secretion of saliva and the principal salivary enzyme glucose oxidase. Caterpillars with inhibited saliva production feed at similar rates as the untreated caterpillars, pupate, and emerge as adults. Glucose oxidase has been suggested to increase the caterpillar's survival through the suppression of inducible anti-herbivore defenses in plants. Tobacco (Nicotiana tabacum) leaves fed on by caterpillars with ablated salivary glands had significantly higher levels of nicotine, an inducible anti-herbivore defense compound of tobacco, than leaves fed upon by caterpillars with intact labial salivary glands. Tomato (Lycopersicon esculentum) leaves fed upon by caterpillars with suppressed salivary secretions showed greatly reduced evidence of hydrogen peroxide formation compared to leaves fed upon by intact caterpillars. These two methods are useful techniques for determining the role that saliva plays in manipulating plant anti-herbivore defenses.

Corpus Christianorum Series Apocryphorum. Une collection au profil original, portée par un projet de recherche collectif

(Résumé de l'ouvrage) In 1953 the first fascicle of the first volume of the Corpus Christianorum was published. Now, fifty years later, this series has established itself as one of the great scientific enterprises in the field of patristic and medieval studies. We offer this birthday-present to ourselves, our old and new collaborators and our friends as a celebration of what has been achieved, as a survey of where we currently stand and as an insight into our future. The book opens with an essay on fifty years of the Corpus Christianorum. It tells the story of how the enterprise started as an ambitious yet limited project and how it developed into what it is today: a conglomerate of many different research projects located in different places all over the world. The second part presents a florilegium of patristic and medieval texts, all of which have been edited in the series, some only recently, others long ago. The selection has been made by a group of scholars representing the variety of interests reflected in the subseries of the Corpus Christianorum. At the end of the volume an Onomasticon has been added. It gives a complete survey of all the text-editions published to date. This "mini-clavis" will make it easier to find one's way in the library of the Corpus Christianorum.

Régulation de la religion par l'Etat. Nouvelles perspectives

Analyser les modalités de la régulation de la religion constitue une étape importante pour expliquer la recomposition de la religion en modernité tardive. Face aux interprétations dérivées des concepts d'individualisation ou de privatisation, l'affirmation peut apparaître provocante, puisqu'elle met en question l'idée d'autonomie du sujet croyant et la pertinence de l'utilisation sociologique du terme privé. Le traitement de cette problématique est particulièrement adéquat pour évaluer le rôle de l'État. Même si ce dernier n'est qu'un des agents de régulation à côté des médias, des organisations religieuses..., il contribue de façon souveraine au filtrage de la religion « acceptable ». Son mode de gestion varie d'un pays à l'autre, allant du pluralisme libéral au pluralisme technocratique. L'élaboration d'une typologie de ces modes de gestion s'avère donc indispensable. Sa vérification peut s'opérer au travers de l'étude comparative de la place faite à la religion dans les programmes scolaires. Elle éclaire en particulier le caractère pluraliste des États démocratiques et leur capacité à articuler valeurs économiques et valeurs humanistes. An analysis of the ways in which religion is regulated constitutes an important step in understanding the reconstructions of religion in late modernity. Such a stance can appear provocative, especially if contrasted with explanations that derive from concepts such as individualisation or privatisation, since it puts into question both the autonomy of the individual believer and the aptness of the term "private" in sociological understanding. These issues are particularly relevant when it comes to evaluating the role of the state. It is true that the latter is but one source of control, alongside the media, or religious organisations...; its influence is, however, dominant when it comes to deciding which forms of religion are, or are not, "acceptable". The methods vary from one country to another, ranging from liberal pluralism to technocratic pluralism. Hence the need to elaborate a typology, illustrating the different ways of working. It can be tested by comparing the place given to religion in different school systems. Above all such an approach reveals the pluralist character of the democratic state and its capacity to articulate both economic and humanistic values.
