Adolescencias, cultura y subjetividad : la violencia en las escuelas y las respuestas institucionales

El presente trabajo intenta acercar los avances parciales del proyecto de investigación "Adolescencias, Cultura y Subjetividad. La violencia en las escuelas y las políticas institucionales". El trabajo aborda la problemática de la violencia en las escuelas por lo que se enfoca el estudio en las formas de vinculación, la construcción de subjetividad y la cultura como una expresión del ethos epocal, y de inscripción social de los adolescentes. En este sentido, también nos interesa indagar acerca cuáles son las políticas institucionales que se despliegan con el fin de dar respuesta a dicha problemática.Fil: García, Silvia Mónica.

Supplement: "Localization and broadband follow-up of the gravitational-wave transient GW150914" (2016, ApJL, 826, L13)

This Supplement provides supporting material for Abbott et al. (2016a). We briefly summarize past electromagnetic (EM) follow-up efforts as well as the organization and policy of the current EM follow-up program. We compare the four probability sky maps produced for the gravitational-wave transient GW150914, and provide additional details of the EM follow-up observations that were performed in the different bands

Consequences of chronic bacterial infection in Drosophila melanogaster.

Even when successfully surviving an infection, a host often fails to eliminate a pathogen completely and may sustain substantial pathogen burden for the remainder of its life. Using systemic bacterial infection in Drosophila melanogaster, we characterize chronic infection by three bacterial species from different genera - Providencia rettgeri, Serratia marcescens, and Enterococcus faecalis-following inoculation with a range of doses. To assess the consequences of these chronic infections, we determined the expression of antimicrobial peptide genes, survival of secondary infection, and starvation resistance after one week of infection. While higher infectious doses unsurprisingly lead to higher risk of death, they also result in higher chronic bacterial loads among the survivors for all three infections. All three chronic infections caused significantly elevated expression of antimicrobial peptide genes at one week post-infection and provided generalized protection again secondary bacterial infection. Only P. rettgeri infection significantly influenced resistance to starvation, with persistently infected flies dying more quickly under starvation conditions relative to controls. These results suggest that there is potentially a generalized mechanism of protection against secondary infection, but that other impacts on host physiology may depend on the specific pathogen. We propose that chronic infections in D. melanogaster could be a valuable tool for studying tolerance of infection, including impacts on host physiology and behavior

Phase II Study of Velcade (R) Plus Mabthera (R) In Relapsed Follicular Lymphomas.

Background: Velcade ® (V) and Mabthera ® (M) have demonstrated an individual considerable efficacy in the treatment of non Hodgkin’s lymphoma. The aim of this study was to evaluate the efficacy and safety of the combination of V and M in patients with relapsed Follicular lymphoma (FL). Methods: Patients (pts) with histologic documentation of CD20+ FL , measurable and active disease, received : 1.3 mg/m2 of V on days 1-4-8-11 every 21 days for 6 cycle and M 375 mg/m2 on day 1 of each cycle from cycle III to VI. Two additional doses of M were administered alone after cycle VI, every 21 days (cycle VII and VIII). Response was assessed after 2 and 8 cycles using the NCI recommendations for Non-Hodgkin’s Lymphomas. Results: At the time of current analysis, initial planned accrual of 41 evaluable pts was not completed. From 2007 to now 37 pts entered into the trial. The pts characteristics at baseline were: median age 66 years (range: 46-84), male 51% , stage IV 43 % elevated values of LDH, 27%, and of Beta2microglobulin 41%. The FLIPI score was calculated in 34 pts (92%) and 11 pts (31%) had a poor prognostic score (> 3). The median number of previous immuno/chemotherapy regimens was 2 (range:1-3), and the median duration of last remission before registration into trial was 23 months (range: 3-67). In four out of the 37 pts who entered into the trial, the treatment is ongoing and thirty-three pts were evaluable for response. The overall response rate in the intent to treat analysis was 58% (19 pts ), of which 16 pts (49%) obtained complete response (CR) and 3 (9%) partial response (PR). Stable disease was seen in 1 pt (3%). Eight pts (24%) had progressive disease and 2 (6%) pts were lost at follow-up. Three pts (9%) had to stop the treatment: one pt (3%) for grade IV peripheral neuropathy, one pt (3%) refused to continue the treatment after 2 cycle and one pt (3%) died during the treatment for toxicity . After a median follow up of 14 month (0-44), the median overall survival and the event free survival were not reached. Overall, 2 pts relapsed (10 %) and 1 pt (5 %) showed a progression of disease. A total of five pts died, four because of lymphoma progression, and one for toxicity during treatment. Complete response are ongoing in 14 pts . Toxicity was evaluable in 33 patients. We observed the following grade 1/2 adverse events: neuropathy (10 pts), neutropenia (2 pts), infection (5 pts), constipation (4 pts), rash (2 pts), fatigue (1 pt). Further we saw the following grade 3/4 adverse events: thrombocytopenia (5 pts), neuropathy (5 pts), neutropenia (1 pt) and infection with fever(1 pt). Three patient interrupted the treatment due to severe neuropathy. Conclusions: The combination of V+M is associated with acceptable toxicity and a promising percentage of response. Further follow-up is required to evaluate the response duration and survival in the whole group of patient
