A class of imprimitive groups
2010
We classify imprimitive groups inducing the alternating group A4 on the set of blocks, with the inertia subgroup satisfying some very natural geometrical conditions which force the group to operate linearly.
The Role of the Classical Pathway for the Bactericidal Effect of Normal Sera Against Gram-Negative Bacteria
1985
Many gram-negative bacteria are killed after treatment with normal serum. This phenomenon was already described in 1889 by Buchner. The serum-bactericidal effect is abolished when serum has been incubated for 30 min at 56° C. Gram-positive bacteria are less sensitive than gram-negative bacteria to direct killing, although gram-positive cocci are opsonized by the action of serum mediated by antibodies and complement (Inoue et al. 1968; Johnston et al. 1969). Normal sera exhibit bactericidal and bacteriolytic properties against some gramnegative strains; whereas, other gram-negative strains are serum resistant. It has been shown that serum from C4-deficient guinea pigs is able to kill some gr…

The bactericidal activity of normal serum was first described by Buchner in 1889 (10). This effect is abolished when serum has been incubated for 30 min at 56°C. Gram positives are less sensitive than Gram negative bacteria to direct killing, although gram positive cocci are opsonized by the action of serum mediated by antibodies and complement (22). It was found that most of the smooth strains of gram negative bacteria are serum resistant; whereas, the corresponding rough forms are extremely serum sensitive (32, 37). Thus evidence was provided that the composition of the bacterial surface may influence the reaction of the bacteria with the lytic system. The bacteriolytic properties of seru…

Meeting Report: The 11th International Conference on Differentiation Therapy and Innovative Therapeutics in Oncology
2007
The International Conference on Differentiation Therapy group of clinicians and researchers has met for more than 20 years and the most recent meeting in 2005 was held in Shanghai, China ( [1][1]). This group fostered the required networks to translate these novel strategies to clinical practice, as

Brain Oscillatory and Hemodynamic Activity in a Bimanual Coordination Task Following Transcranial Alternating Current Stimulation (tACS): A Combined …
2018
Motor control is associated with synchronized oscillatory activity at alpha (8–12 Hz) and beta (12–30 Hz) frequencies in a cerebello-thalamo-cortical network. Previous studies demonstrated that transcranial alternating current stimulation (tACS) is capable of entraining ongoing oscillatory activity while also modulating motor control. However, the modulatory effects of tACS on both motor control and its underlying electro- and neurophysiological mechanisms remain ambiguous. Thus, the purpose of this study was to contribute to gathering neurophysiological knowledge regarding tACS effects by investigating the after-effects of 10 Hz tACS and 20 Hz tACS at parietal brain areas on bimanual coord…
La identidad de la diversidad funcional en la comunicación mediada por la tecnología
2017
El objeto de estudio de la investigación que a continuación se presenta gravita sobre el cambio ontológico que impone la tecnología en el ser humano. En concreto, el desarrollo de tecnologías de ayuda aplicadas a Sistemas Alternativos de Comunicación representa un interesante ejemplo de cómo dichos soportes actúan en la base de las interacciones sociales, la comunicación y, cómo esta mediación modifica la propia autoimagen e imagen social de la persona que la emplea. El presente estudio se centra en las personas con parálisis cerebral o enfermedad degenerativa neuronal y en la transformación identitaria que padecen al poderse comunicar con soportes autónomos de alta tecnología. La hipótesis…
