2. A clear differentiation of cDNA variants of many COSII genes into the variation partition specified by I. tenuissima or I. littoralis from that by I. trifida. 3. Three species-homolog-specified and one sweetpotato-specific variation partitions among 293 different COSII cDNAs, and two or three out of the four partitions among cDNA variants of 306 COSII genes. We then constructed hybridization networks from two concatenations of 16 and 4 alignments of 8 homologous COSII cDNA regions each, which included three taxa of expressed homoeologs in a triple-partition combination from the 16 or 4 sweetpotato COSII genes and 5 taxa each of respective cDNA homologs from the three sweetpotato relatives and I. nil, and inferred a species tree embodying both networks. The species tree predicted close-relative origins of three partly differentiated sweetpotato subgenomes.CWD is an emergent prion disease that now affects cervid species on three continents. CWD is efficiently spread in wild and captive populations, likely through both direct animal contact and environmental contamination. Here, by longitudinally assaying in feces of CWD-exposed white-tailed deer by RT-QuIC, we demonstrate fecal shedding of prion seeding activity months before onset of clinical symptoms and continuing throughout the disease course. We also examine the impact of simulated environmental conditions such as repeated freeze-thaw cycles and desiccation on fecal prion seeding activity. We found that while multiple (n = 7) freeze-thaw cycles substantially decreased fecal seeding activity, desiccation had little to no effect on seeding activity. Finally, we examined whether RT-QuIC testing of landscape fecal deposits could distinguish two premises with substantial known CWD prevalence from one in which no CWD-infected animals had been detected. In the above pilot study, this distinction was possible. We conclude that fecal shedding of CWD prions occurs over much of the disease course, that environmental factors influence prion seeding activity, and that it is feasible to detect fecal prion contamination using RT-QuIC.Multiple arguments for or against the presence of 'urban' settlements in the Early Bronze Age of the southern Levant have identified the need to compare these settlements against their rural hinterlands through multiple lines of evidence. This meta-analysis of zooarchaeological data from the region compares and identifies patterns of animal production, provisioning and consumption between the supposed "urban" and rural sites of the southern Levant from the Early Bronze (EB) against the (more widely recognised urban) Middle Bronze (MB) Ages. It also identifies distinct and regionally specific patterns in animal production and consumption that can be detected between urban and rural sites of the southern Levant. The taxonomic and age profiles from EB Ia and Ib sites do not demonstrate any urban versus rural differentiation patterning, even though fortifications appear in the EB Ib. Beginning in the EB II and clearly visible in the EB III, there is differentiation between rural and urban sites in the taxonomic and age proportions. Differentiation is repeated in the MB II. The clear differentiation between "urban" and rural zooarchaeological assemblages from the EB II-III and MB suggest that rural sites are provisioning the larger fortified settlements. This pattern indicates that these sites are indeed urban in nature, and these societies are organized at the state-level. From the EB II onwards, there is a clear bias in the large centres towards the consumption of cattle and of subadult sheep and goats with a corresponding bias in smaller rural sites towards the consumption of adult sheep and goats and a reduced presence of cattle. After the emergence of this differential pattern, it disappears with the decline in social complexity at the end of the Early Bronze Age, only to come 'back again' with the re-emergence of urban settlement systems in the Middle Bronze Age.MOTIVATION Much effort has been invested in the identification of protein-protein interactions using text mining and machine learning methods. The extraction of functional relationships between chemical compounds and proteins from literature has received much less attention, and no ready-to-use open-source software is so far available for this task. METHOD We created a new benchmark dataset of 2,613 sentences from abstracts containing annotations of proteins, small molecules, and their relationships. Two kernel methods were applied to classify these relationships as functional or non-functional, named shallow linguistic and all-paths graph kernel. Furthermore, the benefit of interaction verbs in sentences was evaluated. RESULTS The cross-validation of the all-paths graph kernel (AUC value 84.6%, F1 score 79.0%) shows slightly better results than the shallow linguistic kernel (AUC value 82.5%, F1 score 77.2%) on our benchmark dataset. Both models achieve state-of-the-art performance in the research area of relation extraction. Furthermore, the combination of shallow linguistic and all-paths graph kernel could further increase the overall performance slightly. We used each of the two kernels to identify functional relationships in all PubMed abstracts (29 million) and provide the results, including recorded processing time. AVAILABILITY The software for the tested kernels, the benchmark, the processed 29 million PubMed abstracts, all evaluation scripts, as well as the scripts for processing the complete PubMed database are freely available at https//github.com/KerstenDoering/CPI-Pipeline.Despite being the subject of intensive research, tuberculosis, caused by Mycobacterium tuberculosis, remains at present the leading cause of death from an infectious agent. Secreted and cell wall proteins interact with the host and play important roles in pathogenicity. These proteins are explored as candidate diagnostic markers, potential drug targets or vaccine antigens, and more recently special attention is being given to the role of their post-translational modifications. With the purpose of contributing to the proteomic and glycoproteomic characterization of this important pathogen, we performed a shotgun analysis of culture filtrate proteins of M. tuberculosis based on a liquid nano-HPLC tandem mass spectrometry and a label-free spectral counting normalization approach for protein quantification. We identified 1314 M. Selleck PIK-90 tuberculosis proteins in culture filtrate and found that the most abundant proteins belong to the extracellular region or cell wall compartment, and that the functional categories with higher protein abundance factor were virulence, detoxification and adaptation, and cell wall and cell processes.
