The phonon dispersion curves of cubic BaTiO3 have been computed within a first-principles approach and the results compared to the experimental data. The curves obtained are very similar to those reported for KNbO3 by Yu and Krakauer (Phys. Rev. Lett., 74, 4067 (1995)). They reveal that correlated atomic displacements along [100] chains are at the origin of the ferroelectric instability. A simplified model illustrates that spontaneous collective displacements will occur when a dozen of aligned atoms are coupled. The longitudinal interatomic force constant between nearest neighbour Ti and O atoms is relatively weak in comparison to that between Ti atoms in adjacent cells. The small coupling between Ti and O displacements seems however necessary to reproduce a linear ferroelectric instability. [less ▲]

Adults of Myzostoma cirriferum are obligate ectocommensals that live on the surface of comatulids of the genus Antedon from the North East Atlantic and Mediterranean. M. cirriferum is a simultaneous hermaphrodite which reproduces by transferring spermatophores that penetrate the integument of the receiver myzostomes. Fertilized eggs are shed into the water column where they divide. After the embryonic stage that lasts 24h, the motile individuals enter into the larval stage. Three types of larvae are recognized in M. cirriferum: the spherical protrochophora (occuring between 24 and 48h after the laying), the pyriform trochophora (48-72h), and the pyriform, setigerous metatrochophora (72h until metamorphosis). The body of the protrochophora and trochophora is made of undifferenciated cells and ciliated cells. Two types of undifferentiated cells are present: the first contact the thin cuticle, have microvilli and include a lot of yolk droplets; the second are internal and have no or only a few yolk droplets. No basal lamina has been observed in the body of these larvae. Huge tissular modifications occur in the young metatrochophora (i.e. 96-144h after laying). The epidermis is now well underlined by a basal lamina. Two pairs of 4 chaetae lie on the sides of the larval body and a sensory caudal appendage is differentiating at its end. The digestive system is forming. It is composed of a pharynx included in an extensible introvert and a closed, internal digestive cavity. The nervous system appears and is composed of an epispheral nervous mass, a peripharyngeal collar, nervous processes and sensory cells. The anatomy of the late metatrochophora stays unchanged until metamorphosis, which generally occurs 7 days after laying. The body of the larva is made of twelve cell types. Seven are ectodermal: covering cells and ciliated cells make up most of the epidermis; primary chaetoblasts and lateral cells form the chaetal follicles; secondary chaetoblasts will build the chaetae of juveniles after metamorphosis; pharyngeal cells and myoepithelial cells make up the pharyngeal epithelium. The other cell types are neurodermal (neurons and sensory cells), endodermal (the digestive cells that border the digestive cavity) and mesodermal (parenchyma cells and muscle cells) [less ▲]

Despite recent improvements in the management of Crohn's disease, steroids are still the most efficacious treatment in flare ups of the disease. However they have significant side effects and are only effective in the short term. There is no consensus regarding initial dose or duration of corticotherapy. With 1 mg/Kg a day of oral prednisolone given for 3 to 7 weeks, 92% of the patients achieve clinical remission. Topical acting oral corticosteroids such as budesonide seem to represent an important therapeutic advance due to their better tolerance. The promising results of budesonide in mild and moderate flare ups need to be confirmed and its indication in severe disease beside high dose prednisolone has to be clarified. [less ▲]

The 27-kDa heat shock protein (Hsp27) is constitutively expressed in motor and sensory neurons of the brainstem. Hsp27 is also rapidly induced in the nervous system following oxidative and cellular metabolic stress. In this study, we examined the distribution of Hsp27 in the rat medulla oblongata by means of immunohistochemistry after the vagus nerve was cut or crushed. After vagal injury, rats were allowed to survive for 6, 12, 24 h, 2, 4, 7, 10, 14, 30, or 90 days. Vagus nerve lesions resulted in a time-dependent up-regulation of Hsp27 in vagal motor and nodose ganglion sensory neurons that expressed Hsp27 constitutively and de novo induction in neurons that did not express Hsp27 constitutively. In the dorsal motor nucleus of the vagus nerve (DMV) and nucleus ambiguus, the levels of Hsp27 in motor neurons were elevated within 24 h of injury and persisted for up to 90 days. Vagal afferents to the nucleus of the tractus solitarius (NTS) and area postrema showed increases in Hsp27 levels within 4 days that were still present 90 days postinjury. In addition, increases in Hsp27 staining of axons in the NTS and DMV suggest that vagus nerve injury resulted in sprouting of afferent axons and spread into areas of the dorsal vagal complex not normally innervated by the vagus. Our observations are consistent with the possibility that Hsp27 plays a role in long-term survival of distinct subpopulations of injured vagal motor and sensory neurons. [less ▲]
