Stem cell mobilization chemotherapy with gemcitabine is effective and safe in myeloma patients with bortezomib-induced neurotoxicity.

Vinorelbine chemotherapy with granulocyte-colony stimulating factor (G-CSF) stimulation is a widely applied non-myelosuppressive mobilization regimen in Switzerland for myeloma patients, but its neurotoxic potential limits its use in patients with bortezomib-induced polyneuropathy. In this single-center study, we alternatively evaluated safety and effectiveness of gemcitabine chemotherapy with G-CSF for mobilization of autologous stem cells. Between March 2012 and February 2013, all bortezomib-pretreated myeloma patients planned to undergo first-line high-dose melphalan chemotherapy received a single dose of 1250 mg/m(2) gemcitabine, with G-CSF started on day 4. The 24 patients in this study had received a median of four cycles of bortezomib-dexamethason-based induction. Bortezomib-related polyneuropathy was identified in 21 patients (88%) by clinical evaluation and a standardized questionnaire. Administration of gemcitabine mobilization did not induce new or aggravate pre-existing neuropathy. Stem cell mobilization was successful in all 24 patients, with a single day of apheresis being sufficient in 19 patients (78%). The median yield was 9.51 × 10(6) CD34+ cells/kg. Stem collection could be accomplished at day 8 in 67%. Our data suggest that single-dose gemcitabine together with G-CSF is an effective mobilization regimen in myeloma patients and a safe alternative non-myelosuppressive mobilization chemotherapy for myeloma patients with bortezomib-induced polyneuropathy.

Neurotoxicity of stem cell mobilization chemotherapy with vinorelbine in myeloma patients after bortezomib treatment.

Vinorelbine chemotherapy with G-CSF stimulation is the standard mobilization regimen in Switzerland for multiple myeloma patients. However, with the increasing use of bortezomib during induction treatment, adding the neurotoxic compound vinorelbine for mobilization may aggravate bortezomib-induced polyneuropathy. In this retrospective single-center study, we aimed to explore vinorelbine mediated neuropathy in 106 consecutive bortezomib pretreated myeloma patients. We confirmed that vinorelbine with G-CSF represents a reliable and effective regimen for mobilization of autologous stem cells. However, the single administration of 35 mg/m(2) vinorelbine added significant neurotoxicity. We found that 24 patients (24%) reported vinorelbine mediated neurotoxicity: Aggravation of bortezomib-induced neuropathy was observed in 17 patients (17%), and vinorelbine mobilization induced first occurrence of polyneuropathy in additional 7 patients (7%). We observed that development of polyneuropathy was not associated with differing survival rates. Finally, affected patients reported polyneuropathy associated disease burden as "very high" in 13% and "high" in 50%. Our data indicate that a single administration of vinorelbine to mobilize autologous stem cells is associated with significant additional polyneuropathy in bortezomib pretreated myeloma patients. The efficacy of vinorelbine mobilization should be balanced against its neurotoxic potential.

Racing against Time: Varying Patterns of Social Mobilization in Serbia and Georgia

After the collapse of the Soviet Union and Yugoslavia, a number of actors started to engage in the power struggle for the opportunities to shape the new order in successive nation-states. In Serbia and Georgia historically hegemonic Orthodox Christian churches were among the firsts in the frontlines for political and economic power. More than a decade has passed since the so-called Coloured Revolutions in Georgia and Serbia, and the Orthodox churches still remain participants of an ongoing socio-political transition of these states. The revival of public role of religion appeared temporary in Serbia followed by a gradual decline of an influence of the Orthodox Church over political life and legal process. However, in Georgia the public and political role of religion increased rather than declined albeit changed shape. Examining the degree to which the two Orthodox churches can influence the political agenda in Serbia and Georgia, the paper attempts to understand how church-State relations work in practice. By bringing rich empirical data from the field (70 interviews with (arch)bishops, priests and religious clerics in Georgia and Serbia added to field observations), the paper reflects on the themes under which the two Orthodox churches mobilize public protest in Serbia and Georgia. The paper further looks at varying State responses and their broader implication for church-state problematique.

Sediment mobilization deposits from episodic subsurface fluid flow—A new tool to reveal long-term earthquake records?

Subsurface fluid flow can be affected by earthquakes; increased spring activity, mud vol- cano eruptions, groundwater fluctuations, changes in geyser frequency, and other forms of altered subsurface fluid flow have been documented during, after, or even prior to seismic shaking. Recently discovered giant pockmarks on the bottom of Lake Neuchâtel, Switzerland, are the lake-floor expression of subsurface fluid flow. They discharge groundwater from the Jura Mountains karstic aquifers and experience episodically increased subsurface fluid flow documented by subsurface sediment mobilization deposits at the levees of the pockmarks. In this study, we present the spatio-temporal distribution of event deposits from these phases of sediment expulsion and of multiple time-correlative mass-transport deposits. We report five striking instances of concurrent multiple subsurface sediment deposits and multiple mass- transport deposits since late glacial times, for which we propose past earthquakes as a trigger. Comparison of this new event catalogue with historic earthquakes and other independent paleoseismic records suggests that initiation of sediment expulsion requires a minimum mac- roseismic intensity of VII. Thus, our study presents for the first time sedimentary deposits resulting from increased subsurface fluid flow as a paleoseismic proxy.

Calcium mobilization from the endoplasmic reticulum to the mitochondria during apoptosis in prostate cancer

Previous studies have implicated Ca2+ fluxes in the control of apoptosis but their exact roles in regulating the process remain obscure. Because Ca2+ can serve as a signal for cytochrome c release from isolated mitochondria, we hypothesized that alterations in intracellular Ca2+ compartmentalization might serve as a release signal in whole cells undergoing apoptosis. Exposure of human PC-3 prostate adenocarcinoma cells to staurosporine or DNA damaging agent (doxorubicin) but not to anti-Fas antibody led to early release of Ca2+ from the endoplasmic reticulum and subsequent accumulation of Ca2+ within mitochondria. Both events were blocked in cells stably transfected with Bcl-2 but were not affected by treatment with the pancaspase inhibitor, zVADfmk. The effects of staurosporine were associated with re-localization of Bax from the cytosol to both endoplasmic reticular and mitochondrial membranes. Neither ER Ca 2+ pool depletion nor mitochondrial Ca2+ uptake were observed in DU-145 cells that possess a frameshift mutation in the Bax gene unless wild-type Bax was restored via adenoviral gene transfer. Cytochrome c release and downstream features of apoptosis were attenuated by treatment with an inhibitor of mitochondria) Ca2+ uptake (RU-360). Although, direct pharmacological ER Ca2+ pool emptying in cells treated with thapsigargin did not lead to early cytochrome c release, pretreatment of cells with staurosporine dramatically sensitized mitochondria to thapsigargin-induced cytochrome c release. Together, our data demonstrate that ER-to-mitochondrial Ca2+ fluxes promote cytochrome c release and apoptosis in cells exposed to some (but not all) pro-apoptosic stimuli. ^

Microbe Hunters Revisited – Paul de Kruif and the Beginning of Popular Science Writing

Paul de Kruif is credited with being one of the first popular science writers for the general public. He received his Ph.D. from the University of Michigan in 1916 and worked at the Rockefeller Institute under Simon Flexner. After being fired in 1922 for publishing a scathing article on medical research, de Kruif caught the attention of Sinclair Lewis, who used his scientific background to write his Pulitzer Prize winning novel, Arrowsmith. In 1926, de Kruif published Microbe Hunters which recounted the exploits and discoveries of 14 renowned microbiologists from von Leeuwenhoek to Pasteur, Ross, Paul Ehrlich and Walter Reed. Microbe Hunters became a best seller, was translated into 18 languages, and formed the basis of two Hollywood movies, "Yellow Jack" and "The Magic Bullet." Generations of young readers were captivated by the vivid protrayal of these men and their discoveries.

Nacimiento de la Fiesta Nacional de la Vendimia : polifonía de lo popular y lo culto

El presente trabajo forma parte de una búsqueda en la que a partir del análisis de discursos acerca de la Fiesta de la Vendimia actual (ya sea a modo de comentario, critica o descripción)surgen interrogantes relacionados con su identidad y sus participantes. Se orienta, entonces, a la forma en que la Fiesta se va gestando. Describe los festejos previos a su oficialización haciendo referencia a fenómenos de inversión, circulación y conformación del campo festivo (legitimado y consagrado a partir de la participación de la Iglesia y del Estado).Reflexiona sobre el significado de los silencios en relación a músicas populares y concluye en el intento de explicarnos las relaciones entre lo "popular" y lo "culto" en la génesis de la Fiesta como tensión dialéctica que emerge de un universo cultural compartido no homogéneo.

Lenguajes en intersección : culto y popular en la configuración del campo musical

A partir de evidenciar algunas de las acepciones más cristalizadas del término "popular", se propone quebrar la identidad popular/ masivo y generar otra dimensión en el análisis de las producciones musicales. Desde esta configuración, se construye -con fines analíticos- un sistema que involucra, por un lado, el par culto/popular -pensado como un continuo de intersecciones entre lenguajes- y, por el otro, el concepto masividad. El análisis que se desprende del sistema lenguajes musicales/masividad, donde se manifiestan los cruces entre los lenguajes utilizados en las producciones musicales, se potencia mediante la aplicación de otros modelos que pueden permitirnos visualizar intersecciones en los públicos, es decir en la recepción y en los consumos

Zamba azul y la renovación de la canción popular argentina : convergencias disciplinares para un análisis musical significativo

Una de las problemáticas planteadas por la musicología es la limitación del análisis musical centrado sólo en las estructuras musicales. Con el presente trabajo intentamos realizar un análisis a través de una aproximación múltiple a una obra; una mirada o enfoque integral que permita llegar a un nivel de análisis más significativo, a través de la articulación de las diferentes aproximaciones. En este caso nos hemos ocupado de una obra emblemática dentro de la producción de Tito Francia, compositor mendocino en cuyo catálogo se reúnen géneros populares con géneros académicos.
