Compared to offspring of women with 25(OH)D in Q1, offspring problem scores were -4.80 (95% confidence interval [CI] -8.29, -1.33) units lower for Q2 vs Q1, -5.64 (95% CI -9.60, -1.68) units lower for Q3 vs Q1, and -4.70 (95% CI -8.59, -0.82) units lower for Q4 vs Q1. Vitamin D was not associated with offspring competence score.

Higher maternal vitamin D was associated with lower offspring behaviour problems and not associated with socioemotional competence. These data indicate the association of maternal vitamin D and offspring development may be dependent on the specific developmental component being investigated.

However, the details of the electron-/proton-transfer mechanism are still unknown. In particular, the driving force of the electron transfer from the type-1 copper (T1Cu) site to the type-2 copper (T2Cu) site is ambiguous. Here, we explored the two possible proton-transfer channels, the high-pH proton channel and the primary proton channel, by using two-layered ONIOM calculations. Our calculation results reveal that the driving force for electron transfer from T1Cu to T2Cu comes from a remote water-mediated triple-proton-coupled electron-transfer mechanism. In the high-pH proton channel, the water-mediated triple-proton transfer occurs from Glu113 to an intermediate water molecule, whereas in the primary channel, the transfer is from Lys128 to His260. Subsequently, the two channels employ another two or three distinct proton-transfer steps to deliver the proton to the nitrite substrate at the T2Cu site. These findings explain the detailed proton-/electron-transfer mechanisms of copper-containing nitrite reductase and could extend our understanding of the diverse proton-coupled electron-transfer mechanisms in complicated proteins.A large number of older adults (65+ years) live on their own, and can experience high levels of loneliness. However, accessing activities to engage with their community can be difficult either due to their age and associated comorbidities, such as frailty, or due to financial reasons, for lacking the funds to access transport to activities. The aim of this study was to evaluate an existing service in the North West of England, Community Connectors, which enables people aged 18 and above to access social activities within their community in order to reduce loneliness and social isolation. This study only included middle-aged and older adults. A total of 13 semi-structured interviews were performed after people had taken part in the 14-week Community Connectors programme. Data were coded by two research team members by using thematic analysis. Members of the public were involved in the design of this study, and in the dissemination. Between June 2017 to September 2018, 234 older adults and 53 middle-aged adults were referred to Community Connectors. Four themes emerged from the interviews falling out of society; easy self-referral; structured supportive services; and reconnecting with community. Services often depend on individuals making the first step to access, however, without easy or facilitated access people can becoming isolated. Participants reported on how Community Connectors provided easy and open access that enabled better response to individual needs. The structured support provided individuals with confidence in engaging with community activities and enhanced individuals' social networks. Community Connectors enables middle-aged and older adults to engage with social activities in their community, and thus helps participants to feel less lonely and more socially connected. Future work needs to quantitatively measure the impacts of the service on loneliness, depression, and social connectedness in order to fully understand their impact.Abscisic acid (ABA) signals regulating stomatal aperture and water loss are usually studied in detached leaves or isolated epidermal peels and at infrequent timepoints. Measuring stomatal ABA responses in attached leaves across a time course enables the study of stomatal behaviour in the physiological context of the plant. Infrared thermal imaging is often used to characterize steady-state stomatal conductance via comparisons of leaf surface temperature but is rarely used to capture stomatal responses over time or across different leaf surfaces. We used dynamic thermal imaging as a robust, but sensitive, tool to observe stomatal ABA responses in a whole plant context. We detected stomatal responses to low levels of ABA in both monocots and dicots and identified differences between the responses of different leaves. Using whole plant thermal imaging, stomata did not always behave as described previously for detached samples in Arabidopsis, we found no evidence for fast systemic ABA-induced stomatal closure, and in barley, we observed no requirement for exogenous nitrate during ABA-induced stomatal closure. Thus, we recommend dynamic thermal imaging as a useful approach to complement detached sample assays for the study of local and systemic stomatal responses and molecular mechanisms underlying stomatal responses to ABA in the whole plant context.

Clinical significance of left atrial (LA) function and geometry in patients with dilated cardiomyopathy (DCM) remains uncertain.

LA geometric parameters assessed by cardiac magnetic resonance (CMR) predict the prognosis in patients with DCM.

The present study included patients with DCM and sinus rhythm who underwent CMR between December 2007 and April 2018. LA volume was measured using CMR. LA sphericity index was computed as the ratio of the measured maximum LA volume by the volume of a sphere with maximum LA length diameter.

We included 255 patients in this study. During the mean follow-up of 3.92 years, hospitalization for HF occurred in 37 patients. The LA sphericity index was significantly higher in patients with hospitalization for HF than in those without (0.78 ± 0.35 vs. 0.58 ± 0.18, p < .001). SGI-1027 in vitro Multivariable Cox regression analysis identified a higher LA sphericity index as an independent predictor of hospitalization for HF. Patients were categorized based on the median of LA sphericity index.
