Background ⁄ Aims: The aim of this study was to assess gait characteristics during simple and dual task in patients with mild cognitive impairment (MCI) and compare them with those of healthy elderly subjects and mild Alzheimer s disease (AD) patients. Methods: We proposed a gait analysis to appreciate walking (simple task and dual task) in 14 MCI, 14 controls and six AD subjects who walked at their preferred speed. A 20-second period of stabilized walking was used to calculated stride frequency, stride length, symmetry and regularity. Speed walking was measured by electrical photocells. Results: Variables measured during simple and dual tasks showed an alteration of motor function as well in mild AD patients as in MCI patients. Conclusion: At the end of this preliminary study, we defined a specific gait pattern for each cognitive profile. Further researches appear necessary to enlarge the study cohort. [less ▲]

The clinical hallmarks of Parkinson’s disease (PD) are movement poverty and slowness (i.e. bradykinesia), muscle rigidity, limb tremor or gait disturbances. Parkinson’s gait include slowness, shuffling, short steps, freezing of gait (FoG) and/or asymmetries in gait. There are currently no validated clinical instruments or device that allow a full characterization of gait disturbances in PD. As a step towards this goal, a four accelerometer-based system is proposed to increase the number of parameters that can be extracted to characterize parkinsonian gait disturbances such as FoG or gait asymmetries. After developing the hardware, an algorithm has been developed, that automatically epoched the signals on a stride-by-stride basis and quantified, among others, the gait velocity, the stride time,the stance and swing phases, the single and double support phases or the maximum acceleration at toe-off, as validated by visual inspection of video recordings during the task. The results obtained in a PD patient and an healthy volunteer are presented. The FoG detection will be improved using time-frequency analysis and the system is about to be validated with a state-of-the-art 3D movement analysis system. [less ▲]

Our understanding of how the Galaxy was formed and evolves is severely hampered by the lack of precise constraints on basic stellar properties such as distances, masses and ages. Here, we show that solar-like pulsating red giants represent a well-populated class of accurate distance indicators, spanning a large age range, which can be used to map and date the Galactic disc in the regions probed by observations made by the CoRoT and Kepler space telescopes. When combined with photometric constraints, the pulsation spectra of such evolved stars not only reveal their radii, and hence distances, but also provide well-constrained estimates of their masses, which are reliable proxies for the ages of the stars. As a first application, we consider red giants observed by CoRoT in two different parts of the Milky Way, and determine precise distances for ˜2000 stars spread across nearly 15 000 pc of the Galactic disc, exploring regions which are a long way from the solar neighbourhood. We find significant differences in the mass distributions of these two samples which, by comparison with predictions of synthetic models of the Milky Way, we interpret as mainly due to the vertical gradient in the distribution of stellar masses (hence ages) in the disc. In the future, the availability of spectroscopic constraints for this sample of stars will not only improve the age determination, but also provide crucial constraints on age-velocity and age-metallicity relations at different Galactocentric radii and heights from the plane.

The galactose alpha 1-3 galactose (Gal alpha 1-3 Gal) residue is a carbohydrate widely distributed in many non-human mammals. Since Gal alpha 1-3 Gal residues are described on the cell surface of tumor cells, we have examined the possibility of their expression on human trophoblastic cells at different stages of placental implantation and in various pregnancy-associated conditions. Using immunohistochemical methods, Gal alpha 1-3 Gal was demonstrated on interstitial and vascular trophoblast during pregnancy. For villous trophoblast, the staining disappeared in second trimester pregnancies. The density of staining for Gal alpha 1-3 Gal was increased in highly invasive trophoblast (mole and choriocarcinoma) and decreased in poorly invasive specimens (spontaneous abortion, XO monosomia). No cells displaying Gal alpha 1-3 Gal at their surface were identified in some segments of spiral arteries from pre-eclamptic women. The anti-Gal antibody titer increased in the first trimester of pregnancy and in the sera of pre-eclamptic and eclamptic patients. These findings suggest that Gal alpha 1-3 Gal residues could be considered as markers for trophoblast invasive capacity and that the binding of maternal anti-Gal antibodies to the trophoblast could contribute to limit trophoblastic invasion and thus participate to the immunological control of implantation.

A brain slice preparation was used to examine the effects of galanin on the spontaneous firing rate of locus coeruleus noradrenergic neurons. Galanin (10(-9)-10(-7) M), added to the bath, inhibited the firing of 14 out of 19 neurons in a concentration-dependent manner. The observed effect was quite variable, ranging from 20 to 100% at 10(-7) M. Experiments performed in low-Ca2+, high-Mg2+ medium also showed a significant inhibition by galanin (10(-7) M) in three out of five neurons, which suggests that the peptide acts directly. [less ▲]

En su _Introducción al camelo_, publicada en 1967, el escritor y periodista argentino Esteban Peicovich reunió una serie de textos no literarios y los presentó como si fueran poemas. El autor ampliaría posteriormente el número de textos y los pondría bajo un nuevo título: _Poemas plagiados_. A pesar de que dicho volumen haya sido editado tres veces a ambas orillas del Atlántico desde el año 2000 —lo que resulta muy notable para un libro de poemas—, hasta ahora apenas ha sido desflorado por la crítica periodística, sin que la crítica académica se haya fijado todavía en él. Sin embargo, los _Poemas plagiados_ constituyen un objeto de estudio ideal en el que ensayar un análisis pionero de pragmática literaria: los poemas de Peicovich constituyen actos de habla falsificados en los que la función ilocutiva original de textos cotidianos es transformada, difuminada o simplemente suprimida; sus posibilidades perlocutivas, por el contrario, se multiplican. Peicovich dispone de una manera estudiada los elementos de cada poema (título, texto y fuente), lo que permite al lector escoger entre dos lecturas diferentes pero no excluyentes: la lectura poética, propiciada por una serie de transformaciones paratextuales, y la lectura referencial (conservada mediante la mención de la fuente original situada al final de cada texto). El resultado es una expresión poética espontánea que dignifica documentos cotidianos y aun prosaicos, y en la que el lector se ve ejercitado de continuo en un lúdico movimiento de ida y vuelta del proceso de interpretación. La aclaración final del origen del poema de hecho juega con su horizonte de expectativas y demuestra el carácter colectivo de la creación poética —resaltada por un Lautréamont— en la que quehacer artístico y recepción del espectador se complementan. Nuestra comunicación definirá, pues, la pragmática de los _Poemas plagiados_, destacando las estrategias que poetizan estos textos —fragmentación, versificación, títulos recontextualizadores, etc.—. Además situaremos la práctica del «poema plagiado» en la historia literaria, esbozando su genealogía y descendencia, en relación con el estatuto ambiguo que parece caracterizar la producción de otros autores sudamericanos contemporáneos, como Roberto Bolaño, Nicanor Parra o César Aira. No es tampoco una casualidad que Peicovich dedicase varios libros y entrevistas a Jorge Luis Borges, cuyas obras usurpan a veces los atuendos de la no ficción. Los _Poemas plagiados_ demuestran que, a pesar de lo tantas veces repetido durante todo el siglo XX, el carácter literario de un texto no procede del empleo de un código lingüístico especial, distinto del de la comunicación cotidiana.

We present the first search for galaxy counterparts of intervening high-z (2 < z < 3.6) sub-damped Lyα absorbers (sub-DLAs) and DLAs towards gamma-ray bursts (GRBs). Our final sample comprises five intervening sub-DLAs and DLAs in four GRB fields. To identify candidate galaxy counterparts of the absorbers we used deep optical- and near-infrared imaging, and low-, mid- and high-resolution spectroscopy acquired with 6-m to 10-m class telescopes, the Hubble and the Spitzer Space Telescopes. Furthermore, we used the spectroscopic information and spectral-energy-distribution fitting techniques to study them in detail. Our main result is the detection and spectroscopic confirmation of the galaxy counterpart of the intervening DLA at z = 3.096 in the field of GRB 070721B (zGRB = 3.6298) as proposed by other authors. We also identify good candidates for the galaxy counterparts of the two strong Mg ii absorbers at z = 0.6915 and 1.4288 towards GRB 050820A (zGRB = 2.615). The properties of the detected DLA galaxy are typical for Lyman-break galaxies (LBGs) at similar redshifts; a young, highly star-forming galaxy that shows evidence for a galactic outflow. This supports thehypothesis that a DLA can be the gaseous halo of an LBG. In addition, we report a redshift coincidence of different objects associated with metal lines in the same field, separated by 130–161 kpc. The high detection rate of three correlated structures on a length scale as short as ~150 kpc in two pairs of lines of sight is intriguing. The absorbers in each of these are most likely not part of the same gravitationally bound structure. They more likely represent groups of galaxies. [less ▲]
