TL;DR: Children who have FASD are more prevalent among first graders in this Midwestern city than predicted by previous, popular estimates.
Abstract: OBJECTIVES: To determine the prevalence and characteristics of fetal alcohol spectrum disorders (FASD) among first grade students (6- to 7-year-olds) in a representative Midwestern US community. METHODS: From a consented sample of 70.5% of all first graders enrolled in public and private schools, an oversample of small children (≤25th percentile on height, weight, and head circumference) and randomly selected control candidates were examined for physical growth, development, dysmorphology, cognition, and behavior. The children’s mothers were interviewed for maternal risk. RESULTS: Total dysmorphology scores differentiate significantly fetal alcohol syndrome (FAS) and partial FAS (PFAS) from one another and from unexposed controls. Alcohol-related neurodevelopmental disorder (ARND) is not as clearly differentiated from controls. Children who had FASD performed, on average, significantly worse on 7 cognitive and behavioral tests and measures. The most predictive maternal risk variables in this community are late recognition of pregnancy, quantity of alcoholic drinks consumed 3 months before pregnancy, and quantity of drinking reported for the index child’s father. From the final multidisciplinary case findings, 3 techniques were used to estimate prevalence. FAS in this community likely ranges from 6 to 9 per 1000 children (midpoint, 7.5), PFAS from 11 to 17 per 1000 children (midpoint, 14), and the total rate of FASD is estimated at 24 to 48 per 1000 children, or 2.4% to 4.8% (midpoint, 3.6%). CONCLUSIONS: Children who have FASD are more prevalent among first graders in this Midwestern city than predicted by previous, popular estimates.

TL;DR: It is shown for the first time that IL-1β at physiologically relevant concentrations causes an increase in intestinal epithelial TJ permeability.
Abstract: IL-1β is a prototypical proinflammatory cytokine that plays a central role in the intestinal inflammation amplification cascade. Recent studies have indicated that a TNF-α- and IFN-γ-induced increase in intestinal epithelial paracellular permeability may be an important mechanism contributing to intestinal inflammation. Despite its central role in promoting intestinal inflammation, the role of IL-1β on intestinal epithelial tight junction (TJ) barrier function remains unclear. The major aims of this study were to determine the effect of IL-1β on intestinal epithelial TJ permeability and to elucidate the mechanisms involved in this process, using a well-established in vitro intestinal epithelial model system consisting of filter-grown Caco-2 intestinal epithelial monolayers. IL-1β (0–100 ng/ml) produced a concentration- and time-dependent decrease in Caco-2 transepithelial resistance. Conversely, IL-1β caused a progressive time-dependent increase in transepithelial permeability to paracellular marker inulin. IL-1β-induced increase in Caco-2 TJ permeability was accompanied by a rapid activation of NF-κB. NF-κB inhibitors, pyrrolidine dithiocarbamate and curcumin, prevented the IL-1β-induced increase in Caco-2 TJ permeability. To further confirm the role of NF-κB in the IL-1β-induced increase in Caco-2 TJ permeability, NF-κB p65 expression was silenced by small interfering RNA transfection. NF-κB p65 depletion completely inhibited the IL-1β-induced increase in Caco-2 TJ permeability. IL-1β did not induce apoptosis in the Caco-2 cell. In conclusion, our findings show for the first time that IL-1β at physiologically relevant concentrations causes an increase in intestinal epithelial TJ permeability. The IL-1β-induced increase in Caco-2 TJ permeability was mediated in part by the activation of NF-κB pathways but not apoptosis.

TL;DR: This analysis of three independent datasets of gross primary productivity shows that, across diverse ecosystems, drought recovery times are strongly associated with climate and carbon cycle dynamics, with biodiversity and CO2 fertilization as secondary factors.
Abstract: Drought, a recurring phenomenon with major impacts on both human and natural systems, is the most widespread climatic extreme that negatively affects the land carbon sink. Although twentieth-century trends in drought regimes are ambiguous, across many regions more frequent and severe droughts are expected in the twenty-first century. Recovery time-how long an ecosystem requires to revert to its pre-drought functional state-is a critical metric of drought impact. Yet the factors influencing drought recovery and its spatiotemporal patterns at the global scale are largely unknown. Here we analyse three independent datasets of gross primary productivity and show that, across diverse ecosystems, drought recovery times are strongly associated with climate and carbon cycle dynamics, with biodiversity and CO2 fertilization as secondary factors. Our analysis also provides two key insights into the spatiotemporal patterns of drought recovery time: first, that recovery is longest in the tropics and high northern latitudes (both vulnerable areas of Earth's climate system) and second, that drought impacts (assessed using the area of ecosystems actively recovering and time to recovery) have increased over the twentieth century. If droughts become more frequent, as expected, the time between droughts may become shorter than drought recovery time, leading to permanently damaged ecosystems and widespread degradation of the land carbon sink.

TL;DR: The authors investigated the effect of weekly quizzes and multiple choice criterial tests on student learning and concluded that short answer quizzes produced more robust benefits than multiple choice quizzes, while recall tests were more beneficial than recognition tests for subsequent memory performance.
Abstract: Laboratory studies show that taking a test on studied material promotes subsequent learning and retention of that material on a final test (termed the testing effect). Educational research has virtually ignored testing as a technique to improve classroom learning. We investigated the testing effect in a college course. Students took weekly quizzes followed by multiple choice criterial tests (unit tests and a cumulative final). Weekly quizzes included multiple choice or short answer questions, after which feedback was provided. As an exposure control, in some weeks students were presented target material for additional reading. Quizzing, but not additional reading, improved performance on the criterial tests relative to material not targeted by quizzes. Further, short answer quizzes produced more robust benefits than multiple choice quizzes. This pattern converges with laboratory findings showing that recall tests are more beneficial than recognition tests for subsequent memory performance. We conclude that in the classroom testing can be used to promote learning, not just to evaluate learning.
