PSA Decrease with Fulvestrant Acetate in a Hormone-Resistant Metastatic Prostate Cancer Patient: A Case Report
Metastatic prostate cancer is an incurable disease. After a period of hormone sensitivity that allows for the use of antiandrogens, the disease invariably progresses to a situation of androgen-independent growth, which deserves the consideration or the use of chemotherapy. As many of these patients are elderly and fragile, treatment with chemotherapy is challenging. Therefore, new drugs are required. Preclinical evidence supports the role of estrogen receptor (ER) signaling in prostate cancer. In this paper, we report the first published evidence of PSA control in a patient with metastatic prostate cancer treated with fulvestrant acetate

In this paper, we provide an approach for adaptation in multiagent systems based on a multidimensional transition deliberation mechanism (MTDM). This approach considers transitions in multiple dimensions and is aimed at obtaining the adaptation with the highest potential for improvement in utility based on the costs of adaptation. The approach provides an accurate measurement of the impact of the adaptation since it determines the organization that is to be transitioned to as well as the changes required to carry out this transition. We show an example of adaptation in a service provider network environment in order to demonstrate that the measurement of the adaptation consequences taken by the MTDM improves the organization performance more than the other approaches.Manuscript received January 2, 2012; revised July 26, 2012; accepted August 7, 2012.

Final Report of the First Refractory Germ Cell Tumor Treated with Sunitinib Malate
Patients with advanced germ cell tumors can be cured with cisplatin-based chemotherapy, but the outcome remains unsatisfactory for patients with relapsed disease, including those patients with refractory disease after bone marrow transplantation. Targeted therapies have changed the standard of care for many advanced solid tumors. We have identified, in the literature, potential targets for the treatment of refractory germ cell tumors, and applied to a patient with a refractory disease. We chose sunitinib for this purpose. To our knowledge, this is the first case to be treated with sunitinib, and we have found a promising activity
A computer-based support system for cooperative tasks in nursing homes
Different studies have shown the benefits of a cooperative activities programme for the elderly. Members of a group with similar abilities or disabilities are often encouraged by having the opportunity to share their experiences, knowledge, or opinions. Nevertheless, when caregivers try to plan specific cooperative activities, different aspects, as the individual needs of each person, should be taken into account, which notably increases the complexity of that planification. This paper proposes a computer-based support tool for recreational therapists which facilitates the management task of grouping elderly people into cooperative groups for existing activities. To do this, an iterative learning process is proposed allowing the formation of proper distributions of elderly people into activities. (c) 2019 The Authors.

Problemas resueltos de análisis de riesgos en instalaciones
Enginyeria Industrial. 369: Seguretat i Anàlisi de RiscosBeing able to define which products are creative and which are not in a totally objective way with just one rater is of great importance. Accordingly, this study was conducted with the aim of identifying which methods of evaluating product creativity respond best to the requirements established for a method, namely, it must be useful, objective and simple to apply in enterprises. Likewise, this work also seeks to determine their shortcomings and the possible modifications or adaptations needed to correct them. To accomplish this goal, three known methods of evaluating creativity were analysed and applied to five products in order to determine their creative value, by means of a single rater. The findings are validated by evaluating creativity through questionnaires answered by experts in order to obtain a set of reference values for each parameter that creativity depends on.
The analysis of the results, both graphically and numerically, reveals a tendency of the different metrics to display similar results, although they do not coincide in absolute terms due to the different scales and formats used for each metric. The conclusions show the most common shortcomings when it comes to evaluating creativity and, therefore, being able to propose global improvements that should be implemented in order to create a metric for objective creativity
An intelligent self-configurable mechanism for distributed energy storage systems
Next generation of smart grid technologies demand intel-
ligent capabilities for communication, interaction, monitoring, storage,
and energy transmission. Multiagent systems are envisioned to provide
autonomic and adaptability features to these systems in order to gain
advantage in their current environments. In this paper we present a
mechanism for providing distributed energy storage systems (DESSs)
with intelligent capabilities. In more detail, we propose a self-con gurable
mechanism which allows a DESS to adapt itself according to the future
environmental requirements. This mechanism is aimed at reducing the
costs at which energy is purchased from the market.This work has been partially supported by projects TIN2012-36586-C03-01 and TIN2011-27652-C03-01.Alberola Oltra, JM.; Julian Inglada, VJ.; García-Fornes, A.

Análisis termohidraulico de piscinas de combustible gastado PWR
Dentro del estudio de Seguridad en Parada de centrales nucleares se ha analizado el
comportamiento del reactor bajo diferentes secuencias accidentales utilizando códigos
de estimación óptima. Además, en dicha configuración de planta (en parada) las
piscinas de combustible gastado están conectadas mediante el canal de transferencia con
la cavidad de recarga para realizar la recarga de elementos combustibles. En estas
condiciones, un determinado iniciador puede tener consecuencias tanto en el núcleo del
reactor como en las piscinas de combustible gastado. Con el objetivo de analizar el
comportamiento termohidráulico de las piscinas, y tomando como planta de referencia
la central nuclear de Ascó, se ha construido un modelo de TRACE para la piscina
haciendo uso de una componente Vessel-3D en coordenadas cartesianas. Dicho modelo
ha sido utilizado para la simulación de dos escenarios transitorios: uno de ellos supone
la pérdida del sistema de refrigeración de la piscina, mientras que en el segundo se
postula la pérdida del sistema de refrigeración junto con una pérdida de refrigerante a
través del canal de transferencia, ya que es muy importante conocer los tiempos
disponibles de actuación que logren mantener la integridad de los elementos de
combustible gastado frente a una pérdida de refrigerante. Ambos escenarios se han
simulado suponiendo que la piscina se encuentra completamente llena de elementos
combustibles, con lo que la generación de calor residual es la máxima posible.Sánchez Sáez, F.; Serradell García, VJ.; Carlos Alberola, S. (2011). Análisis termohidraulico de piscinas de combustible gastado PWR. Sociedad Nuclear Española. http://hdl.handle.net/10251/71500
Infant gut microbiota modulation by human milk disaccharides in humanized microbiome mice
Human milk glycans present a unique diversity of structures that suggest different mechanisms by which they may affect the infant microbiome development. A humanized mouse model generated by infant fecal transplantation was utilized here to evaluate the impact of fucosyl-α1,3-GlcNAc (3FN), fucosyl-α1,6-GlcNAc, lacto-N-biose (LNB) and galacto-N-biose on the fecal microbiota and host-microbiota interactions. 16S rRNA amplicon sequencing showed that certain bacterial genera significantly increased (Ruminococcus and Oscillospira) or decreased (Eubacterium and Clostridium) in all disaccharide-supplemented groups. Interestingly, cluster analysis differentiates the consumption of fucosyl-oligosaccharides from galactosyl-oligosaccharides, highlighting the disappearance of Akkermansia genus in both fucosyl-oligosaccharides. An increment of the relative abundance of Coprococcus genus was only observed with 3FN. As well, LNB significantly increased the relative abundance of Bifidobacterium, whereas the absolute levels of this genus, as measured by quantitative real-time PCR, did not significantly increase. OTUs corresponding to the species Bifidobacterium longum, Bifidobacterium adolescentis and Ruminococcus gnavus were not present in the control after the 3-week intervention, but were shared among the donor and specific disaccharide groups, indicating that their survival is dependent on disaccharide supplementation. The 3FN-feeding group showed increased levels of butyrate and acetate in the colon, and decreased levels of serum HDL-cholesterol. 3FN also down-regulated the pro-inflammatory cytokine TNF-α and up-regulated the anti-inflammatory cytokines IL-10 and IL-13, and the Toll-like receptor 2 in the large intestine tissue. The present study revealed that the four disaccharides show efficacy in producing beneficial compositional shifts of the gut microbiota and in addition, the 3FN demonstrated physiological and immunomodulatory roles
