Student Pharmacists and Street Children: A Mutually Beneficial Relationship

The Tumaini Children’s Drop-In Center is a daytime drop-in center for the street children of Eldoret, Kenya. It is part of a partnership between the Purdue University College of Pharmacy, the Academic Model Providing Access to Healthcare program, Eldoret community members, and numerous individuals in both Kenya and the US. Through the efforts of local staff and Purdue student pharmacists, who work at the local hospital on an eight-week clinical rotation, the center has helped a population of nearly 400 local street children by providing a safe haven from life on the streets. Purdue student pharmacists aid the center by applying for grants to fund service-learning projects. These projects, run by the students, help provide the children with basic necessities in addition to screening and education sessions regarding local health issues. In turn, the street children aid the students by providing a break from the stress of the hospital and by providing a broader view of what health care should look like

CONTROL DE POSICIÓN Y PRESIÓN PARA MANIPULADOR NEUMÁTICO A TRAVÉS DE PC

El trabajo se basa en la obtención de un sistema de posicionamiento servoneumático, con control de presión del dispositivo de trabajo en la posición de operación, todo esto, gobernado por computador (PC). Para controlar posición y presión se han diseñado controladores PID discretos. Se utiliza una tarjeta de adquisición de datos Lab PC-1200 de National Instruments, y el software LabVIEW, para implementar programas que sirven para la adquisición de datos a través de los diferentes sensores y que son llevados al PC para su procesamiento. Con este sistema se pueden fijar posiciones intermedias a lo largo de un eje de forma muy precisa. La automatización de procesos como: remachado, perforado, estampado, pueden ser perfectamente desarrollados con este sistema propuesto

Towards the solution of the many-electron problem in real materials: Equation of state of the hydrogen chain with state-of-the-art many-body methods

We present numerical results for the equation of state of an infinite chain of hydrogen atoms. A variety of modern many-body methods are employed, with exhaustive cross-checks and validation. Approaches for reaching the continuous space limit and the thermodynamic limit are investigated, proposed, and tested. The detailed comparisons provide a benchmark for assessing the current state of the art in many-body computation, and for the development of new methods. The ground-state energy per atom in the linear chain is accurately determined versus bond length, with a confidence bound given on all uncertainties

Personality traits and environmental choices: On the search for understanding

In this paper we hypothesize that individuals will choose among alternative courses of action for power generation from wind farms according to their personality profiles. Through a factor analysis we found that certain characteristics of personality do indeed have an effect on environmental choice. The study involves an extensive survey based on the Big Five Traits model to find a pattern of choice that will help to better understand environmental decisions and be useful for policy makers to identify target groups and preview reactions to different courses of action. The research is potentially useful for the better preparation and design of publicity material, awareness raising campaigns and information provision for complex or unpopular policies affecting the environment or in environmental education in general. This research is especially interested in shedding some light on how personality is involved in the processes of environmental decision making, despite the limitations of the present study

Transgenic Expression of Soluble Human CD5 Enhances Experimentally-Induced Autoimmune and Anti-Tumoral Immune Responses

CD5 is a lymphoid-specific transmembrane glycoprotein constitutively expressed on thymocytes and mature T and B1a lymphocytes. Current data support the view that CD5 is a negative regulator of antigen-specific receptor-mediated signaling in these cells, and that this would likely be achieved through interaction with CD5 ligand/s (CD5L) of still undefined nature expressed on immune or accessory cells. To determine the functional consequence of loss of CD5/CD5L interaction in vivo, a new transgenic mouse line was generated (shCD5EμTg), expressing a circulating soluble form of human CD5 (shCD5) as a decoy to impair membrane-bound CD5 function. These shCD5EμTg mice showed an enhanced response to autologous antigens, as deduced from the presentation of more severe forms of experimentally inducible autoimmune disease (collagen-induced arthritis, CIA; and experimental autoimmune encephalitis, EAE), as well as an increased anti-tumoral response in non-orthotopic cancer models (B16 melanoma). This enhancement of the immune response was in agreement with the finding of significantly reduced proportions of spleen and lymph node Treg cells (CD4+CD25+FoxP3+), and of peritoneal IL-10-producing and CD5+ B cells, as well as an increased proportion of spleen NKT cells in shCD5EμTg mice. Similar changes in lymphocyte subpopulations were observed in wild-type mice following repeated administration of exogenous recombinant shCD5 protein. These data reveal the relevant role played by CD5/CD5L interactions on the homeostasis of some functionally relevant lymphocyte subpopulations and the modulation of immune responses to autologous antigens
