Cellular and humoral immunity to the 60-kD heat shock protein in inflammatory bowel disease.

1997

Background: Mycobacteria have been considered a possible etiological agent in Crohn’s disease. Since cross-reactivity between epitopes of mycobacterial and self-heat shock protein might represent a potential disease mechanism, we determined the cellular and humoral immune responses to the mycobacterial and the human 60-kD heat shock protein, as well as various control antigens. Methods: We studied samples from 19 patients with Crohn’s disease, 12 patients with ulcerative colitis, and from 19 healthy individuals. T cell responses were studied using a standard proliferation assays to purified recombinant mycobacterial and human 60-kD heat shock protein. Antibody levels were measured by establ…

Group algebras whose units satisfy a group identity

1997

Let F G FG be the group algebra of a torsion group over an infinite field F F . Let U U be the group of units of F G FG . We prove that if U U satisfies a group identity, then F G FG satisfies a polynomial identity. This confirms a conjecture of Brian Hartley.

Seudoartrosis congénita de clavícula asociada a síndrome del estrecho torácico superior: presentación de un caso y revisión de la literatura

1997

La seudoartrosis congénita de clavícula es una patología muy poco frecuente. Generalmente afecta al lado derecho y es asintomática. Su tratamiento quirúrgico sólo está indicado cuando produce una alteración estética en forma de tumoración. Presentamos un caso de seudoartrosis congénita de clavícula asociada a un síndrome de estrecho torácico superior, tratado con la resección de la primera costilla y la sección de la inserción del músculo escaleno anterior en la misma. Congenital pseudoartrosis of the clavicle is a very little frecuent patology. Usually it affects the right side and is asymptomathic. Surgery is only indicated for cosmetic reasons.

Flexible optical implementation of fractional Fourier transform processors. Applications to correlation and filtering

1997

Abstract Recently, in the field of fractional Fourier transforms (FRT) an operation coined “fractional correlation” has been proposed and investigated experimentally. In this paper we propose a new setup for obtaining the fractional correlation, which presents several advantages from the experimental point of view. The fractional filter plane can be adjusted accurately with the help of converging beam illumination and using an adjusting device consisting of a combination of Fresnel zone plates. Moreover the scaling factor between the input pattern and the filter can be adjusted at will. This degree of freedom is of special interest when using SLMs. In addition we present a configuration, ba…

Extraction of dansylated amino acids using the supported liquid membrane technique

1997

Extraction using the supported liquid membrane (SLM) technique demands conditions where the extracted compounds can be made uncharged allowing them to pass through the membrane. For amino acids, being bifunctional, such conditions can not be obtained directly. One way to overcome this problem is to block one of the functionalities by derivatization, utilising the other group for the transport. The SLM extraction of dansylated amino acids was investigated and optimized. It was possible to obtain high extraction efficiencies (>90%) for most amino acids. For amino acids with polar side chains, such high extraction efficiencies were only obtained at low analyte concentrations ( 10 nmol 1-l). Fo…

Verbal and pragmatic coding

1997

Planning reaching and grasping an object requires selective computation of extrinsic (i.e. distance) and intrinsic (i.e. size) object properties, respectively. However, the mechanism for this selection can be partially effective in this process, and nonrelevant object attributes can be used. An experiment was carried out to test whether linguistic information on object properties, as well as sensorial object information, could be automatically involved in movement planning. Subjects were required to reach and grasp a wooden bar, that could have two sizes and could be placed at two spatial positions. An Italian word, either lungo (long) or corto (short) was written on the external face of th…

Incompatibilismo y necesidad contrafáctica

1997

Algunos piensan que este conflicto entre la imagen determinista del mundo y la libertad de decisión es irresoluble, y ello les define como incompatibilistas; mientras que otros consideran que hay modos de integrar ambas intuiciones y merecen, pues, el nombre de compatibilistas. El presente artículo pretende mediar en el debate entre estas dos posiciones. Para ello, reflexionaremos acerca de la naturaleza de los vínculos contrafácticos implicados en las relaciones causales que se presuponen tanto en la imagen determinista del mundo como en nuestras intuiciones acerca de la libertad de decisión. En concreto, nuestra propuesta vendrá a subrayar la debilidad de las estrategias compatibili…

La détermination passive et quelques thématisations particulières en anglais médical

1997

À partir d’exemples caractéristiques issus d’un corpus de 2 115 structures passives tirées de la revue britannique The Lancet, j’ai réalisé une classification originale de ces diathèses passives en trois grandes catégories, à savoir la détermination passive simple, la détermination passive complexe et la détermination passive tronquée. Après avoir précisé en quoi ces opérations de détermination correspondaient à une stratégie énonciative particulière — qu’elle soit réfléchie ou spontanée — mise en œuvre par les médecins, j’ai analysé quelques formes extrêmes, ou déterminations particulières, notamment celles présentées sous la forme d’adjectifs composés. Thanks to 2,115 passive structures c…

cervello, mente e linguaggio: Ippocrate contro il cognitivismo

1997

A partire dali anni 40 del '900, nelle scienze cognitive è dominante il modello sotteso al cognitivismo classico. Secondo questo modello la mente umana funziona come un computer. In questo modello il cervello, come ogni altr parte fisica del corpo, è l'hardware, la mente incorporea e immateriale è il software, e il linguaggio è un modo di funzionamento della mente individuale, Da questo punto di vista, come ribadisce Chomsky in numerosi suoi contributi, la linguistica è una branca della psicologia. Il presente contributo è un tentativo di dimostrare che un simile modello non è universalemte valido, e in particolare non era valido nella Grecia antica. L'autore del De morbo sacro, trattato in…

Tally languages accepted by alternating multitape finite automata

1997

We consider k-tape 1-way alternating finite automata (k-tape lafa). We say that an alternating automaton accepts a language L\(\subseteq\)(Σ*)k with f(n)-bounded maximal (respectively, minimal) leaf-size if arbitrary (respectively, at least one) accepting tree for any (w1, w2,..., wk) ∈ L has no more than $$f\mathop {(\max }\limits_{1 \leqslant i \leqslant k} \left| {w_i } \right|)$$ leaves. The main results of the paper are the following. If k-tape lafa accepts language L over one-letter alphabet with o(log n)-bounded maximal leaf-size or o(log log n)-bounded minimal leaf-size then the language L is semilinear. Moreover, if a language L is accepted with o(log log(n))-bounded minimal (respe…

Les estampes de l'antiguitat en les Observacions d'A.J. Cavanilles

1997

La presencia destacada de las antigüedades entre las láminas que ilustran la obra y, sobre todo, la descripción del Castellar de Meca en Ayora y la excavación de los Banys de la Reina de Calp otorgan a las Observaciones un lugar destacado en la historia de la arqueología. Lo más importante en la aproximación de Cavanilles a la antigüedad es su relativo alejamiento de la erudición clásica frente al interés directo por los objetos y monumentos. Cavanilles representa la primera confluencia entre la historia y las ciencias naturales, punto de arranque de la moderna interpretación al pasado del hombre.

Libertad y responsabilidad moral

1997

¿Son los seres humanos libres y moralmente responsables de sus acciones? El supuesto de que esta pregunta tiene una respuesta categórica ha prevalecido ampliamente en la discusión filosófica contemporánea. La discusión sobre la libertad y la responsabilidad moral se ha movido, en gran parte, en torno a la cuestión de sus relaciones de compatibilidad o incompatibilidad con el determinismo y la necesidad causal, es decir, en un ámbito estrictamente metafísico. En este marco, las respuestas posibles, compatibilismo e incompatibilismo (tanto en su versión libertarista como determinista estricta), resultan insatisfactorias. Esta situación favorece la sospecha de que los conceptos mismos de liber…

High Resolution Solution NMR Structure of the Z Domain of Staphylococcal Protein A. Analysis of Secondary Structure for Free Z Domain and Bounded to …

1997

Staphylococcal protein A (SpA) is a cell-wall-bound pathogenicity factor from the bacterium Staphylcoccus aureus. It exhibits tight binding to many IgG, IgA and IgM molecules at site(s) different from antigen-combining site. Because of their small size and immunoglobulin (IgG)-binding activities, domains of protein A are important targets for protein engineering efforts and for the development of computational approaches for de novo protein folding.
