Determinación por cromatografía de aminoácidos en Iridaea ciliata e lridaea laminarioides

Se estudió el contenido de aminoácidos libres y de aquellos provenientes de hidro/izados de proteínas en Iridaea ciliata e lridaea laminarioides, por cromatografía en papel y en placas de celulosa. La composición de aminoácidos en ambas algas es muy similar. Los aminoácidos glicina, alanina, arginina, ácido glutámico y ácido aspártico son los que se encuentran en mayor proporción

Postconviction Remedies, and Federal Jurisdiction: Tensions in the Allocation of Judicial Power

Postconviction Remedies deals with a subject of great importance to the practitioner of criminal law. It is concerned with the procedures available to persons who seek relief from their convictions after trial and after direct review in the appellate courts. Though not usually a part of the law school curriculum and therefore not part of the attorney\u27s formal training, the intricacies of postconviction remedies must be mastered by the lawyer who wishes to render skillful service to the convicted client. The trial and appeal are important battles, but others remain to be fought which can decide crucial issues seriously affecting the final disposition of the case

Wide Localized Solitons in Systems with Time and Space-Modulated Nonlinearities

In this work we apply point canonical transformations to solve some classes of nonautonomous nonlinear Schr\"{o}dinger equation namely, those which possess specific cubic and quintic - time and space dependent - nonlinearities. In this way we generalize some procedures recently published which resort to an ansatz to the wavefunction and recover a time and space independent nonlinear equation which can be solved explicitly. The method applied here allow us to find wide localized (in space) soliton solutions to the nonautonomous nonlinear Schr\"{o}dinger equation, which were not presented before. We also generalize the external potential which traps the system and the nonlinearities terms.Comment: 19 pages, 5 figure

Critical appraisal of trastuzumab in treatment of advanced stomach cancer

Advanced or metastatic gastric cancer constitutes the majority of patients in clinical practice. In North America, about 70% of cases are advanced or metastatic when diagnosed, which is higher than the 50% reported in Japan. This difference in presentation is reflected in 5-year overall survival, which is about 20% in North America and 40%–60% in Japan. Despite numerous efforts of randomized studies on advanced gastric cancer, no globally accepted standard regimen has yet been established. Systemic chemotherapy provides palliation and prolongs survival, but the prognosis remains poor. Several monotherapies and combined regimens are currently available and vary around the world. Additionally, several molecular targeting agents are under evaluation in international randomized studies. Human epidermal growth factor receptor-2 (HER-2) is overexpressed or amplified in approximately 22% of patients with gastric cancer. Trastuzumab, a recombinant humanized anti-HER-2 monoclonal antibody, is the first biological therapy that has showed a survival improvement by nearly three months (reduced risk of death by 26%). Therefore, trastuzumab in combination with cisplatin is a reasonable treatment option for patients with advanced gastric cancer who are HER-2 positive. This paper will focus on trastuzumab, its chemical and pharmacological characteristics, and the relevant efficacy, safety, and tolerability studies
