A Theoretical Agenda for Entertainment—Education

Abstract: With the growing number of entertainment—education (E—E) interventions worldwide, and the extensive evaluation research on their impacts, the time is ripe to explore in—depth the theoretical underpinnings of entertainment—education. This introductory article provides a historical background to this special issue of Communication Theory on entertainment—education, and charts a 5—pronged theoretical agenda for future research on entertainment—education. Theoretical investigations of entertainment—education should pay greater attention to the tremendous variability among entertainment—education interventions and to the various resistances to entertainment—education interventions. E—E theorizing will also benefit from close investigations of the rhetorical, play, and affective aspects of E—E. Further, E—E “effects” research should consider employing a broader understanding of individual, group, and social—level changes and be more receptive to methodological pluralism and measurement ingenuity.

A 2-Year Prospective Study of Human Papillomavirus Persistence among Women with a Cytological Diagnosis of Atypical Squamous Cells of Undetermined Significance or Low-Grade Squamous Intraepithelial Lesion

Abstract: Background Cervical cancer is caused by persistent infection with human papillomavirus (HPV). Most infections and associated lesions clear spontaneously. It is important to define the determinants and timing of clearance, so that viral persistence can be recognized and managed. Methods We investigated HPV natural history among 4504 subjects from ALTS (Atypical Squamous Cells of Undetermined Significance/Low-Grade Squamous Intraepithelial Lesions Triage Study). A discrete-time Markov model was used to simultaneously describe the prevalence, incidence, and persistence of type-specific HPV infection over 24 months in women with equivocal or mildly abnormal cytological results. Interactions between multiple HPV types infecting the same woman were examined for incidence of new infection (after an HPV-16 infection) and persistence of a current infection within groups defined by phylogenetic relatedness or by carcinogenicity. Results Ninety-one percent (95% credible interval [CI], 90%-92%) of prevalent HPV infections at enrollment cleared within 24 months. The probability that an infection would persist for a further 6 months increased with the duration of infection, from 37% (95% CI, 35%-39%) for a newly observed infection to 65% (95% CI, 61%-70%) for an infection that had already persisted for > or =18 months. No consistent evidence of interactions was found between multiple HPV types regarding the incidence of new infection after an HPV-16 infection or regarding persistence of current HPV infection. Conclusion Although virtually all HPV infections clear within 2 years, the remaining infections have a high potential for persistence and, by implication, progression to precancer and cancer. Once biological and behavioral determinants are controlled for, HPV infections with different types seem to be independent of each other.

Scaling metabolism from organisms to ecosystems

Abstract: Understanding energy and material fluxes through ecosystems is central to many questions in global change biology and ecology1,2,3,4,5,6,7,8,9,10,11. Ecosystem respiration is a critical component of the carbon cycle1,5,6,7 and might be important in regulating biosphere response to global climate change1,2,3. Here we derive a general model of ecosystem respiration based on the kinetics of metabolic reactions11,12,13 and the scaling of resource use by individual organisms14,15. The model predicts that fluxes of CO2 and energy are invariant of ecosystem biomass, but are strongly influenced by temperature, variation in cellular metabolism and rates of supply of limiting resources (water and/or nutrients). Variation in ecosystem respiration within sites, as calculated from a network of CO2 flux towers5,7, provides robust support for the model's predictions. However, data indicate that variation in annual flux between sites is not strongly dependent on average site temperature or latitude. This presents an interesting paradox with regard to the expected temperature dependence. Nevertheless, our model provides a basis for quantitatively understanding energy and material flux between the atmosphere and biosphere.

Autophagy in major human diseases

Abstract: Autophagy is a core molecular pathway for the preservation of cellular and organismal homeostasis. Pharmacological and genetic interventions impairing autophagy responses promote or aggravate disease in a plethora of experimental models. Consistently, mutations in autophagy-related processes cause severe human pathologies. Here, we review and discuss preclinical data linking autophagy dysfunction to the pathogenesis of major human disorders including cancer as well as cardiovascular, neurodegenerative, metabolic, pulmonary, renal, infectious, musculoskeletal, and ocular disorders.
