    Background and Objectives. The study was conducted to evaluate soft tissue hydration and mass through pattern analysis of vector plots as height, normalized resistance, and reactance measurements by bioelectric impedance vector analysis in Taiwanese and Polish college students. Methods. Whole-body measurements were made with ImpediMed bioimpedance analysis SFB7 BioImp v1.55 (Pinkenba Qld 4008, Australia) in 16 Taiwanese and Polish men and 16 Taiwanese and Polish women. Results. Mean vectors of Taiwanese men and women groups versus the Polish men and women groups were characterized by almost the same normalized resistance component with reactance component (separate 95% confidence limits, P < 0.05) indicating that there were no differences of soft tissue hydration and mass. Interpretation and Conclusion. The evaluation of soft tissue hydration and mass through pattern analysis of vector plots as height, normalized resistance, and reactance measurements by bioelectric impedance vector analysis in Taiwanese and Polish college students did not differ between these two diverse ethnic groups. Further observational research investigating these properties in larger groups would be welcomed to elucidate and/or confirm these findings

    An approach to normal polynomials through symmetrization and symmetric reduction

    An irreducible polynomial fFq[X]f\in\Bbb F_q[X] of degree nn is {\em normal} over Fq\Bbb F_q if and only if its roots r,rq,,rqn1r, r^q,\dots,r^{q^{n-1}} satisfy the condition Δn(r,rq,,rqn1)0\Delta_n(r, r^q,\dots,r^{q^{n-1}})\ne 0, where Δn(X0,,Xn1)\Delta_n(X_0,\dots,X_{n-1}) is the n×nn\times n circulant determinant. By finding a suitable {\em symmetrization} of Δn\Delta_n (A multiple of Δn\Delta_n which is symmetric in X0,,Xn1X_0,\dots,X_{n-1}), we obtain a condition on the coefficients of ff that is sufficient for ff to be normal. This approach works well for n5n\le 5 but encounters computational difficulties when n6n\ge 6. In the present paper, we consider irreducible polynomials of the form f=Xn+Xn1+aFq[X]f=X^n+X^{n-1}+a\in\Bbb F_q[X]. For n=6n=6 and 77, by an indirect method, we are able to find simple conditions on aa that are sufficient for ff to be normal. In a more general context, we also explore the normal polynomials of a finite Galois extension through the irreducible characters of the Galois group.Comment: 28 page

    Caspase-2 is upregulated after sciatic nerve transection and its inhibition protects dorsal root ganglion neurons from Apoptosis after serum withdrawal

    Sciatic nerve (SN) transection-induced apoptosis of dorsal root ganglion neurons (DRGN) is one factor determining the efficacy of peripheral axonal regeneration and the return of sensation. Here, we tested the hypothesis that caspase-2(CASP2) orchestrates apoptosis of axotomised DRGN both in vivo and in vitro by disrupting the local neurotrophic supply to DRGN. We observed significantly elevated levels of cleaved CASP2 (C-CASP2), compared to cleaved caspase-3 (C-CASP3), within TUNEL+DRGN and DRG glia (satellite and Schwann cells) after SN transection. A serum withdrawal cell culture model, which induced 40% apoptotic death in DRGN and 60% in glia, was used to model DRGN loss after neurotrophic factor withdrawal. Elevated C-CASP2 and TUNEL were observed in both DRGN and DRG glia, with C-CASP2 localisation shifting from the cytosol to the nucleus, a required step for induction of direct CASP2-mediated apoptosis. Furthermore, siRNAmediated downregulation of CASP2 protected 50% of DRGN from apoptosis after serum withdrawal, while downregulation of CASP3 had no effect on DRGN or DRG glia survival. We conclude that CASP2 orchestrates the death of SN-axotomised DRGN directly and also indirectly through loss of DRG glia and their local neurotrophic factor support. Accordingly, inhibiting CASP2 expression is a potential therapy for improving both the SN regeneration response and peripheral sensory recovery

    <i>Vejamen</i> de Alfonso de Batres para la Academia de 1638 (Manuscrito inédito). Estudio y edición crítica

    During February 1638 the <i>Fiestas de Carnestolendas</i> were celebrated at the Buen Retiro Palace, Madrid. Among the programmed activities, a literary gathering was held, open to numerous poets and courtiers. From this gathering three <i>vejamenes</i> have been preserved: those of Alfonso de Batres, Antonio Coello and Francisco de Rojas Zorrilla. In this paper we analyze and annotate the <i>vejamen</i> that Batres read before His Majesties in the Royal Salon of the Retiro Palace on February 11, 1638.<br><br>Durante el mes de febrero de 1638 se celebraron en el palacio del Buen Retiro las fiestas de Carnestolendas.

En el presente artículo se analiza y edita críticamente el vejamen que Batres defendió ante sus majestades en el Salón Real del Retiro el 11 de febrero de 1638

    Las grafías impenetrables del Quijote en diálogo con los Plomos del Sacromonte

    Much to the readers’ surprise, the lost chronicle of Don Quixote is discovered in the Alcaná of Toledo’s orientalized bazaar, written in Arabic by a Muslim sage by the name of Cide Hamete Benengeli. But the mysterious Arabic history undergoes a strange metamorphosis when it is lost again and rediscovered in a sealed leaden box. Unexpectedly, the chronicle is now extant in Gothic letters. We are thus dealing with a text twice encrypted in impenetrable letters —both Arabic and Gothic—, and the present essay deals precisely with the unfathomable mystery of the chronicle’s unexpected textual confection and its literary consequences.No es pequeña la sorpresa que se lleva el lector al descubrir que la crónica de don Quijote, redactada en árabe, circula clandestinamente en el zoco orientalizado del Alcaná de Toledo. Por más, la historia, que más adelante vuelve a perderse, aparece en una recóndita caja plúmbea, pero esta vez en letras góticas. Estamos ante un texto encriptado con grafías impenetrables doblemente (árabes y góticas) que, por su factura misma, queda aureolado de un misterio que no le pasaría desapercibido al lector contemporáneo. Aquí intentamos esclarecer tal enigma textual y sus consecuencias literarias

    Cervantes y los mecenas: denle una segunda oportunidad y escribirá El Quijote

    This paper deals, on the one hand, with Cervantes’s various patrons who provided him with economic and intellectual support (cardinal Espinosa, cardinal Acquaviva, Ascanio Coloma, the duke of Bejar, Sir Rodrigo de Tapia). On the other, with the difficulties he met with to publish his works and the slight enthusiasm he felt for the protection of a patron, due to Cervantes’s proudness, or to his deep sense of liberty, or even to his personal vision of the rich and powerful. The Count of Lemos, immortalized by Cervantes by dedicating to him his most famous works, proved being mean enough when he forgot and abandoned the riter instead of having invited him to his kingdom of Naples.En este trabajo se destacan los diferentes mecenas a quienes Cervantes dirigió su obra en busca de amparo económico y protección intelectual (el cardenal Espinosa, el cardenal Acquaviva, Ascanio Colonna, el duque de Béjar o don Rodrigo de Osorio). Asimismo, se repasan las dificultades que encontró Cervantes a la hora de publicar sus obras y el escaso entusiasmo que en él despertaba la protección de un mecenas, ya por su orgullosa condición, ya por su hondo sentido de la libertad, ya por su desengaño ante el poder. Ni siquiera el conde de Lemos le concedió el premio de un merecido descanso en su reino de Nápoles, a pesar de haberle dedicado su producción más famosa y de haberle hecho pasar a la posteridad
