Centrosomes in mammalian cells have recently been implicated in cytokinesis; however, their role in this process is poorly defined. Here, we describe a human coiled-coil protein, Cep55 (centrosome protein 55 kDa), that localizes to the mother centriole during interphase. Despite its association with gamma-TuRC anchoring proteins CG-NAP and Kendrin, Cep55 is not required for microtubule nucleation. Upon mitotic entry, centrosome dissociation of Cep55 is triggered by Erk2/Cdk1-dependent phosphorylation at S425 and S428. Furthermore, Cep55 locates to the midbody and plays a role in cytokinesis, as its depletion by siRNA results in failure of this process. S425/428 phosphorylation is required for interaction with Plk1, enabling phosphorylation of Cep55 at S436. Cells expressing phosphorylation-deficient mutant forms of Cep55 undergo cytokinesis failure. These results highlight the centrosome as a site to organize phosphorylation of Cep55, enabling it to relocate to the midbody to function in mitotic exit and cytokinesis.

We provide a compilation of downward fluxes (total mass, POC, PON, BSiO2, CaCO3, PIC and lithogenic/terrigenous fluxes) from over 6000 sediment trap measurements distributed in the Atlantic Ocean, from 30 degree North to 49 degree South, and covering the period 1982-2011. Data from the Mediterranean Sea are also included. Data were compiled from different sources: data repositories (BCO-DMO, PANGAEA), time series sites (BATS, CARIACO), published scientific papers and/or personal communications from PI's. All sources are specifed in the data set. Data from the World Ocean Atlas 2009 were extracted to provide each flux observation with contextual environmental data, such as temperature, salinity, oxygen (concentration, AOU and percentage saturation), nitrate, phosphate and silicate.

Academic demands, new social context, new routines and decrease of the parental control, are factors that may influence the sleep pattern of freshman students at the University. Medical students from the Federal University of Rio Grande do Norte (UFRN) have a full-time course, subjects with high-level content, and, at the first semester, classes begin at 7 a.m. This group composed by young adults who still suffering with delayed sleep phase, common in adolescence, indicating that this class schedule can be inappropriate at this age. The reduction of nocturnal sleep during school days, and the attempt to recover sleep on free days – social jet lag (JLS), suggests that in the first semester, students suffer from high sleep pressure. High sleep pressure may reflect on cognitive tasks and performance. Therefore, the aim of this study was to investigate the relationship between sleep pressure and the academic profile of medical students from the first semester of UFRN, characterizing this population socio-demographically and investigating possible impacts on therestactivity rhytm and academic performance. A sample of 88 students, healthy men and women awswered the following questionnaires: Pittsburgh Sleep Quality (PSQI), Epworth Sleepiness Scale (ESS), Horne & Ostberg Chronotype (HO), Munich Chronotype (MCTQ) and “Health and Sleep” adapted. Actigraphy was used during 14 days to make actogramas and obtain non-parametric variables of the rest-activity rhythm and the grades of the morning schedule were used as academic performance. The JLS was used as a measure of sleep pressure. Statistics significance level was 95%. The population was sociodemographic homogeneous. Most students have healthy lifestyle, practice physical activity, use car to go to the university and take between 15 and 30 minutes for this route. Regarding CSV, most were classify as intermediate (38.6%) and evening (32%) chronotypes, needs to nap during the week, suffer daytime sleepiness and have poor sleep quality. 83% of the sample has at least 1h JLS, which led us to divide into two groups: Group <2h JLS (N = 44) and Group ≥ 2h JLS (N = 44). The groups have differences only in chronotype, showing that most evening individuals have more JLS, however, no differences were found in relation to sociodemographic aspect, rest-activity rhythm or academic performance. The homogeneity of the sample was limited to compare the groups, however, is alarming that students already present in the first half: JLG, poor sleep quality and excessive daytime sleepiness, which can be accentuated through the university years, with the emergence of night shifts and increased academic demand. Interventionsaddressingthe importance of good sleep habits and the change of the class start time are strategies aimed to improve student’s health.

This study aimed to analyze the pattern characteristics of sleep and sleep quality of nurses who worked day and night shifts. This is a study with a quantitative approach, cross-sectional, descriptive. The study was conducted at the University Hospital of Rio Grande do Norte. Data were collected in full in the period from January to September 2015, through the instruments: Pittsburgh Sleep Quality Index and Sleep Diary. Subjects were interviewed according to their work shift, day or night, during the working hours of the nursing team. After being coded and tabulated, data were analyzed using SPSS version 20.0. The study was approved by the Research Ethics Committee of the Federal University of Rio Grande do Norte, in the Opinion No. 751 567. For a description of continuous variables were used position measurements (mean and median), dispersion (standard deviation) and correlation (Spearman correlation test), to a 0.05 significance level. The socio-demographic profile of the sample showed a total of n = 104 participants, distributed in: 64 on day shift and night shift 40; wherein 90.4% are female, aged between 24-45 years, corresponding to 73% of the sample. There was the presence of statistically significant differences for the variables: employment and living habits (inpatient and outpatient sector (p = 0.003), have more than one job (p = 0.002), use cordial (p = 0.021); Sleep pattern: nap time (p = 0.003), sleep latency (p = 0.013), total sleep time (p = 0.001), how it felt to wake up (p = 0.017), quality of nighttime sleep (p = 0.001) and sleep quality (p = 0.007) compared between the day shift and the night shift. It was concluded that shift work has changed the pattern and sleep quality of nurses working day and night shifts.

A partir de la década del noventa, con la consolidación del Estado Neoliberal, se disipa el carácter de derecho social de la educación que había tenido en tiempos del Welfare State o Estado Providencia y, después de atravesar un proceso de metamorfosis, se convierte en un servicio o bien comercializable. En este contexto, la política educativa de los Estados que se inscriben dentro del capitalismo dependiente, es pérfidamente impuesta por los "think tanks" de los organismos de crédito y asesoramiento internacionales, entre ellos, el Banco Mundial. Esta entidad pretendidamente omnisciente plantea una nueva concepción de Educación Básica que constituiría aquel tramo en el que se imparten "lectura y escritura, aritmética básica y solución de problemas" a la que adhieren las burocracias ministeriales locales, con la implementación de los Núcleos de Aprendizaje Prioritarios (NAP). Con esta escueta provisión de saberes se lograría una fuerza laboral más apta, la adopción de prácticas neomalthusianas y sanitarias generales, lo que en conjunto acarrearía la reducción de la pobreza. En este sentido este dispositivo no introduce novedad alguna sino que implica el más llano reciclaje de la Teoría del Capital Humano emergida en la segunda mitad del siglo XX. Sin embargo, el aditamento dentro de estas "recomendaciones" estriba en la imposición de un nuevo artefacto de financiamiento donde la prioridad concedida a la Educación Básica implica la desinversión de los otros niveles educativos. Más allá de esta retórica, el sentido solapado es la conformación de un sujeto disciplinado y un orden social inmune a los conflictos generados por la desigualdad. Esta maquinaria de dominación se complementa con el empobrecimiento de la formación docente, reducida a la adquisición de un repertorio de técnicas de enseñanza. En consecuencia, se le enajena al educador la posibilidad de tomar decisiones autónomamente que involucra el trabajo con el conocimiento
