Asociación entre relaciones románticas y la calidad de sueño percibida por jóvenes universitarios

Introducción: Uno de los aspectos con mayor variación durante la adolescencia es el sueño, el cual se ve afectado por factores biológicos así como por los estados afectivos y emocionales. En esta etapa, los individuos establecen sus primeras relaciones sentimentales románticas, vínculos esenciales para la maduración de las relaciones sociales y psicosexuales. Este trabajo busca determinar la asociación existente entre las relaciones sentimentales románticas y sus características, con la calidad sueño percibida por los jóvenes. Metodología: Estudio realizado en una población de 1794 estudiantes de ciencias de la salud entre los 18 y 25 años de edad en Bogotá, Colombia, entre 2012 y 2013. Se obtuvo una muestra probabilística con asignación proporcional de 443 sujetos, estratificada por programa académico y sexo. Utilizando dos cuestionarios de auto reporte se exploraron las características de las relaciones sentimentales y la calidad de sueño percibida. Resultados: El 64% (IC 95%: 59,4-68,9%) de la población estudiada se encontró en una relación sentimental romántica. Estos sujetos tuvieron latencias de sueño prolongadas con menor frecuencia que quienes no tenían en una relación (p <0,05). La calidad de sueño percibida se asoció al nivel de satisfacción que tuvieron los sujetos en su relación, así como la atracción por su pareja. Rasgos obsesivos, ansiosos, temerosos y evitativos en la relación disminuyeron la calidad de sueño percibida. Conclusión: Las relaciones sentimentales románticas y sus características se asocian con la calidad de sueño percibida por los individuos. Se requieren estudios que determinen causalidad en esta asociación y definan potenciales estrategias de intervención al respecto.

Promoting resilient livelihoods through adaptive social protection: lessons from 124 programmes in South Asia

Adaptive Social Protection refers to efforts to integrate social protection (SP), disaster risk reduction (DRR) and climate change adaptation (CCA). The need to integrate these three domains is now increasingly recognized by practitioners and academics. Relying on 124 agricultural programmes implemented in 5 countries in Asia, this paper considers how these elements are being brought together, and explores the potential gains of these linkages. The analysis shows that full integration of SP, DRR and CCA interventions is still relatively limited but that when it occurs, integration helps to shift the time horizon beyond short-term interventions aimed at supporting peoples’ coping strategies and/or graduation objectives, toward longer-term interventions that can assist in promoting transformation towards climate and disaster resilient livelihood options.

Something is Missing from 124": Confronting Postmodern Absences in Toni Morrison's Beloved"

My thesis is divided into three chapters that build on one another as they show different examples of absences in the historical setting of Beloved and how the characters try to find creative uses of language to overcome them. As I argue that language plays animportant role in a search for meaning, my first chapter is about specific absences of language in Beloved. My second chapter is about the many absent characters in Beloved, such as Baby Suggs' children and husband, Halle, Howard and Buglar. In my third chapter, I analyze entities that are either missing from the text, or which represent a loss to Baby Suggs, Sethe, and Denver

THE TRANSLATION PRODUCTS OF MOLONEY MURINE SARCOMA VIRUS 124 GENOMIC RNA

Murine sarcoma viruses constitute a class of replication-defective retroviruses. Cellular transformation may be induced by these viruses in vitro; whereas, fibrosarcomas may result in animals infected with them in vivo (Tooze, 1973; Bishop, 1978). Hybridization studies suggest that murine sarcoma viruses arose by recombination between nondefective murine leukemia virus sequences and certain cellular sequences present in uninfected mouse cells (Hu et al., 1977). A specific gene product, however, has not been implicated in murine sarcoma virus transformation.^ One line of murine sarcoma virus-producing cells, Mo-MuSV-clone 124, (Ball et al., 1973), was studied biochemically because it mainly produces the sarcoma virus as a pseudotype packaged with helper murine leukemia virus proteins. The sarcoma viral RNA was translated in a sophisticated cell-free protein synthesizing system (Murphy and Arlinghaus, 1978). The translation products were analyzed by a number of techniques, including electrophoresis in denaturing gels of SDS polyacrylamide, immunoprecipitation, and peptide mapping. The major products of the total RNA purified from the virus preparation were shown to have molecular weights of about 63,000 (P63('gag)), 42,000 (P42), 40,000 (P40), 38,000 (P38), and 23,000 (P23). The size class of mRNA coding for each of the cell-free products was estimated using a poly(A) selection technique and sucrose gradient fractionation. These analyses were used to localize the coding information related to each of the in vitro synthesized cell-free products within the sarcoma virus genome.^ The major findings of these studies were: (1) the 5' half of the sarcoma viral RNA codes for the 63,000 dalton polypeptide and 42,000 - 38,000 dalton polypeptides derived from the "gag" gene; and (2) the 3' half of the sarcoma viral RNA codes for a 38,000 dalton polypeptide and possibly derived from the cellular acquired sequences. ^

Relative survival is an adequate estimate of cancer-specific survival: baseline mortality-adjusted 10-year survival of 771 rectal cancer patients.

BACKGROUND The objective of the present investigation is to assess the baseline mortality-adjusted 10-year survival of rectal cancer patients. METHODS Ten-year survival was analyzed in 771 consecutive American Joint Committee on Cancer (AJCC) stage I-IV rectal cancer patients undergoing open resection between 1991 and 2008 using risk-adjusted Cox proportional hazard regression models adjusting for population-based baseline mortality. RESULTS The median follow-up of patients alive was 8.8 years. The 10-year relative, overall, and cancer-specific survival were 66.5% [95% confidence interval (CI) 61.3-72.1], 48.7% (95% CI 44.9-52.8), and 66.4% (95% CI 62.5-70.5), respectively. In the entire patient sample (stage I-IV) 47.3% and in patients with stage I-III 33.6 % of all deaths were related to rectal cancer during the 10-year period. For patients with AJCC stage I rectal cancer, the 10-year overall survival was 96% and did not significantly differ from an average population after matching for gender, age, and calendar year (p = 0.151). For the more advanced tumor stages, however, survival was significantly impaired (p < 0.001). CONCLUSIONS Retrospective investigations of survival after rectal cancer resection should adjust for baseline mortality because a large fraction of deaths is not cancer related. Stage I rectal cancer patients, compared to patients with more advanced disease stages, have a relative survival close to 100% and can thus be considered cured. Using this relative-survival approach, the real public health burden caused by rectal cancer can reliably be analyzed and reported.
