BACKGROUND There are conflicting reports on the association between daytime napping and incident stroke. This study was designed to investigate the relationship between daytime napping and stroke within a community-based cohort. METHODS The present prospective study was based on the Sleep Heart Health Study. Napping habits were assessed with a self-reported Sleep Habits Questionnaire. Participants with napping habits of different durations and frequencies were followed up until the first stroke occurred or by the final censoring date. Cox proportional hazards models was used to estimate the relationship between napping habits and stroke. RESULTS A total of 4,757 participants (2,219 men, mean age 63.6 ± 11.1 years), were enrolled in this study. Compared with those taking no naps, multivariate proportional hazards models analysis indicated that individuals taking naps with a duration of >60 min [hazard ratio (HR), 2.460; 95% confidence interval (CI), 1.538-3.934] had a higher risk of stroke. And there was also an increased risk of stroke among participants taking naps daily (HR, 1.563; 95% CI, 1.059-2.307) or 5-6 times per week (HR, 1.548; 95% CI, 1.026-2.335). After combining napping durations and frequencies, regular long naps (HR, 1.903; 95% CI, 1.182-3.065) and regular short naps (HR, 1.451; 95% CI, 1.010-2.084) were independent risk factors for incident stroke. CONCLUSIONS Daytime napping with a long duration (>30 min) or a high frequency (≥5 times per week) may increase the risk of stroke. This article is protected by copyright.

Although the biosynthetic pathways of waxes have been extensively characterized, the regulatory mechanisms underlying wax biosynthesis in tomato remain largely unclear. Here, we show that Woolly (Wo), a multicellular trichome regulator, is involved in modulating wax biosynthesis in tomato. Wo enhances the expression of the wax biosynthetic genes SlCER6, SlKCR1, and SlPAS2 and the wax transporter gene SlLTP and thereby promotes wax accumulation. Furthermore, Wo directly binds to the L1-box in the promoter of SlCER6, an essential element of the very-long-chain fatty acid elongase complex. Intriguingly, overexpression (OE) or knockdown of SlMYB31, a MYB transcription factor that physically interacts with Wo in vivo and in vitro, produces marked changes in wax composition, and whereas Wo knockdown inhibits wax accumulation in SlMYB31-OE lines, SlMYB31 knockdown inhibits wax accumulation in Wo-OE lines, implying that these two genes function in the same pathway. Lastly, SlCER6 expression is induced by abscisic acid in a manner that is partially dependent on Wo. These results demonstrate that Wo and SlMYB31 cooperatively control tomato cuticular wax biosynthesis by regulating the expression of SlCER6. This article is protected by copyright.

Both events were rare and extreme but occurred in locations that regularly experience less severe tropical cyclones. We asked if, how and when residents received warnings, what instructions were given, and where and when respondents decided to seek safety. In both examples studied, the residents were aware of the approaching storms, but critical information regarding the severity and potential impacts was either not received in time or not understood fully. This resulted in low levels of evacuation and safety-seeking behaviour. We suggest that planning and public communication need to focus on uncertainty surrounding the severity, impact and multifaceted nature of tropical cyclones and accompanying hazards.

Swelling of an ionic hydrogel immersed in an aqueous solution of disodium cromoglycate reorients the chromonic aggregates, and millimeter-thick optically anisotropic hydrogels are obtained. These anisotropic hydrogels contain the chromonic aggregates at a condensed concentration as high as in the columnar phase of a normal chromonic aqueous solution, although the X-ray diffraction results show much less stacking order and orientational order of the aggregates. Furthermore, anisotropic mechanical properties of the hydrogels are observed due to the anisotropic alignment of the chromonic aggregates. © 2020 WILEY-VCH Verlag GmbH & Co.

To date metrics of thermal stress within marine systems have focussed on coral communities, and less is known about measuring stress relevant to other primary producers, such as seagrasses. An extreme MHW occurred across the Western Australian coastline in the austral summer of 2010/2011, exposing marine communities to summer seawater temperatures 2-5 °C warmer than average. Using a combination of satellite imagery and in situ assessments, we provide detailed maps of seagrass coverage across the entire Shark Bay World Heritage Area (ca. 13,000 km2 ) before (2002, 2010) and after the MHW (2014, 2016). Our temporal analysis of these maps documents the single largest loss in dense seagrass extent globally (1,310 km2 ) following an acute disturbance. Total change in seagrass extent was spatially heterogenous, with the most extensive declines occurring in the Western Gulf, Wooramel Bank and Faure Sill. Spatial variation in seagrass loss was best explained by a model that included an interaction between two heat stress metrics, the most substantial loss occurring when degree heat weeks (DHWm) was ≥ 10 and the number of days exposed to extreme sea surface temperature during the MHW (DaysOver) was ≥ 94. Ground-truthing at 622 points indicated that change in seagrass cover was predominantly due to loss of Amphibolis antarctica rather than Posidonia australis, the other prominent seagrass at Shark Bay. As seawater temperatures continue to rise and the incidence of MHWs increase globally, this work will provide a basis for identifying areas of meadow degradation, or stability and recovery; and potential areas of resilience.
