A Novel Pulse-Chase SILAC Strategy Measures Changes in Protein Decay and Synthesis Rates Induced by Perturbation of Proteostasis with an Hsp90 Inhibitor.

Standard proteomics methods allow the relative quantitation of levels of thousands of proteins in two or more samples. While such methods are invaluable for defining the variations in protein concentrations which follow the perturbation of a biological system, they do not offer information on the mechanisms underlying such changes. Expanding on previous work [1], we developed a pulse-chase (pc) variant of SILAC (stable isotope labeling by amino acids in cell culture). pcSILAC can quantitate in one experiment and for two conditions the relative levels of proteins newly synthesized in a given time as well as the relative levels of remaining preexisting proteins. We validated the method studying the drug-mediated inhibition of the Hsp90 molecular chaperone, which is known to lead to increased synthesis of stress response proteins as well as the increased decay of Hsp90 "clients". We showed that pcSILAC can give information on changes in global cellular proteostasis induced by treatment with the inhibitor, which are normally not captured by standard relative quantitation techniques. Furthermore, we have developed a mathematical model and computational framework that uses pcSILAC data to determine degradation constants kd and synthesis rates Vs for proteins in both control and drug-treated cells. The results show that Hsp90 inhibition induced a generalized slowdown of protein synthesis and an increase in protein decay. Treatment with the inhibitor also resulted in widespread protein-specific changes in relative synthesis rates, together with variations in protein decay rates. The latter were more restricted to individual proteins or protein families than the variations in synthesis. Our results establish pcSILAC as a viable workflow for the mechanistic dissection of changes in the proteome which follow perturbations.

Bonds away : baseball mythology and the 2007 home run chase

In 2007, Barry Bonds hit his 75 6th home run, breaking Hank Aaron's all-time record for most home runs in a Major League career. While it would be expected that such an accomplishment would induce unending praise and adulationfor the new record-holder, Bonds did not receive the treatment typically reserved for a beloved baseball hero. The purpose of this thesis is to assess media representations of the 2007 home run chase in order to shed light upon the factors which led to the mixed representations which accompanied BOlTds ' assault on Aaron's record. Drawingfrom Roland Barthes ' concept of myth, this thesis proposes that Bonds was portrayed in predominantly negative ways because he was seen as failing to embody the values of baseball's mythology. Using a qualitative content analysis of three major American newspapers, this thesis examines portrayals of Bonds and how he was shown both to represent and oppose elements from baseball's mythology, such as youth, and a distant, agrarian past. Recognizing the ways in which baseball is associated with American life, the media representations of Bonds are also evaluated to discern whether he was portrayed as personifYing a distinctly American set of values. The results indicate that, in media coverage of the 2007 home run chase, Bonds was depicted as a player of many contradictions. Most commonly, Bonds' athletic ability and career achievements were contrasted with unflattering descriptions of his character, including discussions of his alleged use of performance-enhancing substances. However, some coverage portrayed Bonds as embodying baseball myth. The findings contribute to an appreciation of the importance of historical context in examining media representations. This understanding is enhanced by an analysis of a selection of articles on Mark McGwire 's record-breaking season in 1998, and careful consideration of, and comparison to, the context under which Bonds performed in 2007. Findings are also shown to support the contemporary existence of a strong American baseball mythology. That Bonds is both condemned for failing to uphold the mythology and praised for personifYing it suggests that the values seen as inherent to baseball continue to act as an American cultural benchmark.

Identificación de Prácticas Empresariales para el Mejoramiento Continuo en Plusagro S.A.S.

Este proyecto que se llevara a cabo en la compañía Plusagro S.A.S. la cual busca mejorar de forma sustancial la cultura organizacional de la compañía, para que desarrolle al máximo las ventajas competitivas que encuentra en el mercado, una de estas grandes ventajas es que al tener la exclusividad de su proveedor principal Kursan. Se vuelve de suma importancia saber que existen otras marcas en el mercado de los productos agrícolas que ofrece Plusagro S.A.S. pero se ha encontrado en común acuerdo con clientes insatisfechos que la calidad de los productos turcos en cuánto a maquinaría lechera es superior a la de otras marcas que importan la maquinaria lechera desde China y Corea. Por esto es fundamental recalcar que Kursan es uno de los productores mundiales de estas máquinas desde 1984 la más fuerte en toda la región de oriente medio y su sede principal está ubicada en Estambul, Turquía. (Kursan, 2014). El negocio de Plusagro S.A.S. se encuentra en uno de los sectores más competitivos del país, pero sin duda alguna es uno de los que más importancia está cobrando, debido al boom agrícola que están viviendo en las regiones ganaderas y agricultoras del país después de las nuevas medidas de inversión que está tomando el gobierno nacional para que sean más competitivas en su desarrollo y crecimiento a nivel nacional. (MinAgricultura, 2014), uno de los ítems más importantes que podemos encontrar, es el hecho de que Colombia y Bélgica iniciaran un plan de trabajo para ampliar el comercio de productos agropecuarios, según el titular de la cartera agropecuaria, este plan de trabajo, que se implementará en enero de 2015, tendrá como prioridad los temas fitosanitarios y de buenas prácticas agrícolas (MinAgricultura, 2014). En lo cual Plusagro S.A.S puede buscar una gran ventaja competitiva que lo lleve a obtener un valor agregado al ya tener conocimiento del mercado europeo será más sencillo entrar a negociar con nuevos proveedores que vengan de este país. También de estos mercados no explorados se pueden llegar a encontrar nuevas prácticas agrícolas, diversas especies animales y nuevas tecnologías en cuanto a maquinaría. De igual forma la empresa ha presentado un crecimiento económico bastante alto, para el poco tiempo que lleva en el mercado, esto se ve evidenciado en las ventas que se realizaron el año 2013 las cuales ascienden a $730.500.000. (Plusagro S.A.S., 2013). Este crecimiento no se debe a solo suerte, este se ha trabajado con diversas estrategias desde el momento en el que se pensó la creación de la empresa, ya que esta nace de la necesidad de los ganaderos y agricultores del sector o localización en donde comenzó a comercializarse los productos, en los municipios de Cumaral, Restrepo y los caseríos como Guacabina y actualmente se ha extendido a diversos municipios del departamento del Meta, como lo son Acacias, Castilla la Nueva, Guamal, Cubarral, San Martín, Puerto López, Barranca de Upía, Puerto Gaitán, Granada y Vista Hermosa . (Plusagro S.A.S., 2014) Se espera que con la realización de este proyecto enfocado en una metodología Sure - Step (Paso Seguro) de Microsoft aplicada a las necesidades de la compañía, se pueda mejorar considerablemente la organización para así mejorar estos promedios de ventas y crecer en el aspecto económico. (Microsoft Dynamics, 2010). Es importante resaltar que ningún proyecto es perfecto y hay que estar consiente que pueden presentarse diversos obstáculos en el camino, pero la idea de implementar la Sure - Step está fundamentada en minimizar estos riesgo que pueden ocurrir en el proyecto y que si se fundamenta en unas fases especificas se pueda gestionar y finalizar con éxito, conllevando a que Plusagro S.A.S. pueda mejorar su cultura organizacional y siga con un crecimiento constante en el mercado.

EdTech Innovator Chase: Rewarding Faculty Innovation through badges

Each semester we celebrate our college EdTech Innovators– everyone who’s using technology to explore new pedagogical approaches. We applaud early adopters for developing best practices, because maybe they’re doing something nobody else has. Those who innovate in the most EdTech areas and (most importantly!) help their colleagues level up, compete for the epic win. The EdTech Innovator Chase, a gamified activity (digital badges) was created to showcase faculty innovations in teaching practices.

A Pollen Chase Experiment; Examining Varying Levels of Embryonic Inbreeding Depression

A pollen chase experiment was performed upon three Costa Rican populations of Witheringia solanacea to examine the breakdown of genetically enforced self incompatibility (SI) and the extent of embryonic inbreeding depression. Self-pollen was applied in the bud, with outcross pollen applied one day later, and outcross pollinations at both intervals as a control. A variety of responses were found among the populations. BOHS readily accepted self pollen and suffered from very low inbreeding depression. Monteverde and Las Cruces both have lower fruit set with self-pollination precedence indicating that bud pollinations can overcome the self-incompatibility response and that embryonic death due to inbreeding depression causes fruit failure. The treatment:control fruit set is higher for the Las Cruces plants indicating stronger SI response Self-precedence seeds from the Las Cruces plants are likely to be outcrossed. Self-precedence seeds from Monteverde are likely selfed.
