However, the patterns of which species and trees are most vulnerable to drought, and the underlying mechanisms have remained elusive, in part due to the lack of relevant data and difficulty of predicting the location of catastrophic drought years in advance. We used long-term demographic records and extensive databases of functional traits and distribution patterns to understand the responses of 20 to 53 species to an extreme drought in a seasonally dry tropical forest in Costa Rica, which occurred during the 2015 El Niño Southern Oscillation event. Overall, species-specific mortality rates during the drought ranged from 0% to 34%, and varied little as a function of tree size. By contrast, hydraulic safety margins correlated well with probability of mortality among species, while morphological or leaf economics spectrum traits did not. This firmly suggests hydraulic traits as targets for future research. This article is protected by copyright.

Ciliates are generally colonized by microorganisms via phagotrophic feeding. In order to study the intracellular bacteria in this ciliate, we have successfully established it in in vitro culture. Herein, we investigated and compared the bacterial community structures of cultured and freshly collected B. ctenopharyngodoni. The results showed that these two groups exhibited different bacterial communities. The most abundant bacterial family in freshly collected samples was Enterobacteriaceae, while in cultured samples it was Fusobacteriaceae. In addition, a key intracellular bacterium, Cetobacterium somerae, was identified in the cytoplasm of cultured ciliates using fluorescence in situ hybridization (FISH). This study shows that ciliates can retain the intracellular bacteria acquired in the natural habitat for quite a long time, but the bacterial community structure of ciliates eventually changes after a long period of cultivation. © 2020 International Society of Protistologists.C-N bond formation is regarded as a very useful and fundamental reaction, which is important for the synthesis of nitrogen-containing molecules in both organic and pharmaceutical chemistry. Noble metal and homogeneous catalysts have been used for C-N bond formation frequently, however, there are still some problems for these catalysts such as high cost, serious pollution and low atom economy. Herein the low-toxic and cheaper iron complex was loaded on CNTs and the heterogenous single-atom catalyst (SAC) named Fe-N x /CNTs was prepared. We applied this SAC to the synthesis of C-N bonds for the first time. It was found that Fe-N x /CNTs was an efficient catalyst for the synthesis of C-N bonds from aromatic amines and ketones. The catalytic performance is markedly excellent with the yield up to 96%, 6-fold higher than that of noble metal catalysts such as AuCl 3 /CNTs and RhCl 3 /CNTs. It was suitable for up to 13 aromatic amine substrates with no additives and 17 enaminones were obtained. By using high-angle annular darkfield scanning transmission electron microscopy (HAADF-STEM) in combination with X-ray adsorption spectroscopy (XAS), we have observed iron species of Fe-N x /CNTs were in good dispersion as single atoms and Fe-N x might be the catalytic active site. This Fe-N x /CNTs catalyst has potential industrial application for its seven runs without any significant loss of activity. © 2020 WILEY-VCH Verlag GmbH & Co.

METHOD Data were analyzed from 149 undergraduate college students with a history of one or more suicide attempts. Three parallel mediation analyses tested the simultaneous mediating effect of family social support and peer social support on the association between suicide attempt disclosure and suicide risk factors. RESULTS Significant total indirect effects in all models indicated family social support and peer social support simultaneously mediated the association between disclosure of suicide attempt and depression, perceived burdensomeness, and thwarted belongingness. The indirect effect on thwarted belongingness via peer social support was stronger than the indirect effect via family social support. CONCLUSIONS Disclosure of suicide attempt was associated with higher social support, which was associated with lower suicide risk factors. In a therapeutic context, it is important to consider social support when discussing disclosure of suicide attempt. © 2020 The American Association of Suicidology.AIM First, to determine the feasibility of using the low-density lipoprotein receptor knockout (LDLR KO) mouse model to study apical periodontitis (AP). Secondly, to investigate the causal relationship between AP and atherosclerosis. It was hypothesized that it would be feasible to induce AP and atherosclerosis in LDLR KO mice and find a difference in atherosclerosis between AP and Sham groups. METHODOLOGY Using a published methodology, AP was induced in LDLR KO mice by exposing the dental pulp of the four first molars (Tx). Shams received only anaesthesia. Mice were fed a high fat, Western-type diet (WTD), to induce atherosclerosis. At 16 weeks, mice were euthanized and aortas collected to measure atherosclerosis lesion burden (oil red O staining). Periapical lesions were validated using micro-CT and histology. Systemic inflammation was measured using a cytokine array. RESULTS Both groups developed a similar degree of atherosclerosis (mean lesion area 7.46 ± 0.44% in the Tx group compared with 7.65 ± 0.46%, in the Sham group, P = 0.
