Components Linked to Health-Related Quality lifestyle Amongst Elderly people Confronted with the Jeju 4·3 Episode.
Humanitarian disaster environments put relief workers at risk, both physically and mentally. Research looking at the growing humanitarian workforce's health and working conditions is lacking.

A questionnaire was presented to ICRC (International Committee of the Red Cross) workers during debriefing between 2016 and 2018. Participants were queried about their experience abroad including security incidents (the primary objective), health, and malaria prevention. Descriptive statistics and multivariate logistic regressions were used for data analysis.

Security incidents were reported by 12% (95/796) of expatriates, mainly armed threats and attacks (83%, 79/95). Accidents or injuries occurred for 7.5% (60/796), of which 42% (25/60) were due to sporting activities and 22% (13/60) to road accidents. Many engaged in risky behaviours (15%, 119/795), such as driving too fast or inebriated (37%, 44/119) and/or engaging in unsafe sex, (unfamiliar partner, no condom) (71%; 84/119). Compliance to malaria prophylaxis was low 43% (113/263). Over 40% (324/795) found the mission more stressful than expected. Almost a third (28%, 219/796) reported worsened health on their return.

Humanitarian aid workers display a worsening of their health when on mission due to violence, accidents and risky behaviours. To preserve their staff's wellbeing, humanitarian organizations should pay attention to medical history, pre-travel training specific to assignment, and continuous medical and psychological support.

We tested this hypothesis in Silene nutans, a gynodioecious Caryophyllaceae, where four distinct genetic lineages exhibited strong reproductive isolation among each other, resulting in chlorotic or variegated hybrids. By sequencing the whole gene content of the four plastomes through gene capture, and a large part of the nuclear genes encoding plastid subunits from RNAseq data, we searched for non-synonymous substitutions fixed in each lineage on both genomes. Lineages of S. nutans exhibited a high level of dN/dS ratios for plastid and nuclear genes encoding most plastid complexes, with a strong pattern of coevolution for genes encoding the subunits of ribosome and cytochrome b6/f that could explain the chlorosis of hybrids. Overall, relaxation of selection due to past bottlenecks and positive selection have driven the diversity pattern observed in S. nutans plastid complexes, leading to plastid-nuclear incompatibilities. We discuss the possible role of gynodioecy in the evolutionary dynamics of the plastomes through linked selection.The albumin family of proteins consists of vitamin-D binding protein/group-specific component (GC), serum albumin (ALB), alpha-fetoprotein (AFP), and afamin (AFM), which are responsible for transporting many ligands throughout the body. The albumin family proteins are physiologically and medically important, but our understanding of their functions and applications is hindered by the dearth of information regarding these proteins' evolutionary relationships and functions in non-mammalian lineages. In this study we investigate the evolution of the albumin family proteins in reptiles, using bioinformatic methods to survey available reptile genomes and transcriptomes for albumin family proteins and phylogenetically characterize their relationships. We reinforce the established evolutionary relationships among the albumin protein family in reptiles, however, they are variable in their number of domains, overall genetic sequence, and synteny. We find a novel absence of the physiologically important ALB in squamates and identify two distinct lineages of AFP, one in mammals and another in reptiles. Our study provides a comparative genomic framework for further studies identifying lineage-specific gene expansions that may compensate for the lack of serum albumin in squamates.Traditionally, taxa following the botanical or zoological codes of nomenclature are diagnosed mainly by morphological characters, although integrative taxonomy advocates including additional features. While many taxonomic studies include DNA sequence analyses, a systematic integration of diagnostic molecular characters (signature characters) is still rare. Here, we suggest a practical guideline for the detection and evaluation of signature characters that provides the means necessary to complement diagnoses and facilitates identifications. The guideline comprises generally applicable criteria exemplified by a case study on an ecologically important group of planktonic protists, the Oligotrichea. The detection of signature characters and their discrete states in multiple sequence alignments is facilitated by the recently developed tool DeSignate. Moreover, we introduce a novel bioinformatic approach to test the influence of different alignment programs on the consistency of signature characters. Our workflow enabled detection of consensus signature characters for most tested taxa and inclusion of such characters in the diagnoses of three orders, eight families, and two genera in the Oligotrichea. The suggested approach is a step towards an integrative taxonomy linking reliable molecular sequence data to organisms' traits.Barbarea, winter-cress, is a genus of 29 species in Brassicaceae, the mustard family, which has emerged as a model for evolution of plant defence and specialised metabolites. BI-3231 mouse Notably, some Barbarea species have evolved the ability to produce triterpenoid saponins as the only ones in Brassicaceae, some of which make plants resistant to important herbivores. Resistance has, however, been lost in a distinct group of plants within B. vulgaris ssp. arcuata, which is genetically strongly diverged from other B. vulgaris plants. This divergence is not reflected present in taxonomy. Thus, a phylogeny is needed to understand evolution and defence in Barbarea. Here, we analysed the nuclear ITS and the plastid matK, ndhF, rps16, and psbA-trnH DNA regions from seven out of 29 Barbarea species, 57 accessions of B. vulgaris, 10 accessions of other Barbarea species, and eight outgroup species, in addition to sequences available from GenBank. All Barbarea species formed a highly supported monophyletic group, separated from sister genera. Several clades seem to have radiated within the genus with no simple branching pattern, and discordant nuclear and plastid DNA phylogenies indicate reticulate evolution and chloroplast capture. One of the complex patterns may have resulted from chloroplast capture of a non-Nordic Barbarea species not included in the study. Two pairs of species were almost identical, B. australis and B. grayi, and B. orthoceras and B. stricta. Despite hybridization, chloroplast capture, and incongruence among the plastid and nuclear DNA data, the high level of intraspecific diversity, coupled with lineage specificity, lead us to recognize three groups of Barbarea vulgaris G-type (glabrous) and P-type (pubescent) individuals of the current B. vulgaris ssp. arcuata as two distinct groups and the current B. vulgaris ssp. vulgaris as the third. Despite the high molecular diversity below species level, the evolutionary history of the saponin-based resistance remains unsettled due to unresolved basal branching.Evolutionary and biogeographic processes determine species richness patterns of vascular plants between Eastern Asia (EA) and Eastern North America (ENA). However, the strikingly higher species richness of EA relative to ENA remains poorly understood from this perspective. Here, we studied the relative importance of biogeographical, evolutionary and ecological factors underlying differences in species richness between EA and ENA in Podophylloideae (Berberidaceae, Ranunculales; in total 10 spp. in EA vs. 2 spp. in ENA). Based on large-scale transcriptome data, our phylogenomic analyses strongly supported Podophylloideae and its two multi-species genera, i.e. Dysosma (EA) and Diphylleia (EA/ENA), as monophyletic groups. Sinopodophyllum hexandrum (EA) was identified as sister to the remainder of Podophylloideae. Dysosma (7 spp.) was recovered as sister to Podophyllum peltatum (ENA), forming an EA-ENA disjunct pair with a strong bias of species diversity in the EA counterpart. Our biogeographic analyses support the 'out-of-Tibet' hypothesis, suggesting that Podophylloideae started to diversify in the Himalaya-Hengduan Mountains (Mid-Miocene) and migrated eastward (since the Late Miocene) into Central-eastern China, Japan, and ENA (only P. peltatum and Diphylleia cymosa). Overall, we conclude that the striking species diversity anomaly between EA and ENA in Podophylloideae may be explained by a combination of (1) a longer period of time available to accumulate species in EA; and (2) a greater diversification rate in EA, which might have been promoted by greater physiographic and environmental heterogeneity in this region.Target sequence capture has emerged as a powerful method to sequence hundreds or thousands of genomic regions in a cost- and time-efficient approach. In most cases, however, targeted regions lack full sequence information for certain samples, due to taxonomic, laboratory, or stochastic factors. Loci lacking molecular data for a large number of samples are commonly excluded from downstream analyses, even though they may still contain valuable information. On the other hand, including data-poor loci may bias phylogenetic analyses. Here we use a target sequence capture dataset of an ecologically and taxonomically diverse group of spiny sunflowers (Asteraceae, or Compositae Barnadesioideae) to test how the inclusion or exclusion of such data-poor loci affects phylogenetic inference. We investigate the sensitivity of concatenation and coalescent approaches to missing data with matrices of varying taxonomic completeness by filtering loci with different proportions of missing samples prior to data analysis. We find that missing data affect both the topology and branch support of the resulting phylogenies. The matrix containing all loci yielded the overall highest node support values, independently of the amount of missing nucleotides. These results provide empirical support to earlier suggestions based on single genes and data simulations that taxa with high amounts of missing data should not be readily dismissed as they can provide essential information for phylogenomic reconstruction.The Ledebouriinae (Scilloideae, Asparagaceae) are a widespread group of bulbous geophytes found predominantly throughout seasonal climates in sub-Saharan Africa, with a handful of taxa in Madagascar, the Middle East, India, and Sri Lanka. Phylogenetic relationships within the group have been historically difficult to elucidate. Here, we provide the first phylogenomic perspective into the Ledebouriinae. Using the Angiosperms353 targeted enrichment probe set, we consistently recovered four major clades (i.e., two Ledebouria clades, Drimiopsis, and Resnova). The two Ledebouria clades closely align with geography, either consisting almost entirely of sub-Saharan African taxa (Ledebouria Clade A), or East African and non-African taxa (Ledebouria Clade B). Our results suggest that the Ledebouriinae likely underwent a rapid radiation leading to rampant incomplete lineage sorting. We additionally find evidence for potential historical hybridization between Drimiopsis and a subclade within Ledebouria Clade A.
