Early endoderm formation in zebrafish requires at least three loci that function downstream of Nodal signaling but upstream of the early endodermal marker sox17: bonnie and clyde (bon), faust (fau), and casanova (cas). cas mutants show the most severe phenotype as they do not form any gut tissue and lack all sox17 expression. Activation of the Nodal signaling pathway or overexpression of Bon or...

Les Lesions Laryngees et oesophayiennes de la maladie herpetique ant ete decrit recem­ment sur 5 cas (Annales de radiologie).  Ces lesions ont evolue vers une stenose orga­nique de l'oesophage dans 3 cas. L'aspzct radiologique de ces stenoses et lear evolution sont tres pronches des stenoses caustiques.  Un cas personnel de stenose oesophagienne de Ce meme type, 3 ans apres une episode aigue ...

1. As found by Sordelli and Mayer, agar adsorbed on bacteria produces agar-reacting antibodies in animals injected with these organisms. 2. False cross-agglutination and precipitin reactions can be produced in sera containing agar-reacting antibodies by organisms grown on agar. Zozaya's publication in this field (3) requires partial revision on this account. 3. There is suggestive immunological...

Crk-associated substrate (Cas) is a tyrosine-phosphorylated docking protein that is indispensable for the regulation of the actin cytoskeletal organization and cell migration in fibroblasts. The function of Cas in neurons, however, is poorly understood. Here we report that Cas is dominantly enriched in the brain, especially the cerebellum, of postnatal mice. During cerebellar development, Cas i...

We previously showed that activation of the small GTPase Cdc42 promotes breast cell migration on a collagen matrix. Here we further define the signaling pathways that drive this response and show that Cdc42-mediated migration relies on the adaptor molecule p130(Cas). Activated Cdc42 enhanced p130(Cas) phosphorylation and its binding to Crk. Cdc42-driven migration and p130(Cas) phosphorylation w...

Résumé L’accouchement d’un fœtus macrosome est une situation relativement fréquente. Il s’agit d’un accouchement à haut risque aussi bien maternel que fœtal. Les principales complications maternelles étaient représentées par l’augmentation du taux de césarienne, d’hémorragie de la délivrance et des déchirures traumatiques cervico-vaginales. La principale complication fœtale était la dystocie de...

BACKGROUND AND PURPOSE Stenosis of the carotid artery may cause reduced hemodynamic and neural function that may be ameliorated with CAS. The goal of this study was to evaluate short- and long-term hemodynamic and clinical effects after CAS. MATERIALS AND METHODS Hemodynamic parameters were acquired by PCT within 1 week before CAS and at 1 week and 1 year (10-13 months) after CAS. In ACA terr...

BACKGROUND To describe geographic variation in population-based rates of carotid artery stenting (CAS) and carotid endarterectomy (CEA) performed in Medicare beneficiaries. METHODS AND RESULTS Medicare claims and enrollment data were used to calculate age, sex, and race-adjusted rates of CAS and CEA for Medicare beneficiaries in each of 306 hospital referral regions between 1998 and 2007. Pro...
