title: The presence of a foreign accent introduces lexical integration difficulties during late semantic processing

description: Previous research suggests that native listeners may be more tolerant to syntactic errors when they are produced in a foreign accent. However, studies investigating this topic within the semantic domain remain conflicting. The current study examined the effects of mispronunciations leading to semantic abnormality in foreign-accented speech. While their EEG was recorded, native speakers of Spanish listened to semantically correct and incorrect sentences produced by another native speaker and a native speaker of Chinese. The anomaly in the incorrect sentences was caused by a subtle mispronunciation (typical or atypical in Chinese-accented Spanish) during a critical word production. While initial-stage semantic processing yielded no accent-specific differences, late processing revealed a persistent N400-effect in the foreign-accent but not in the native-accent. These findings suggest that foreign-accented mispronunciations are more difficult to integrate than native-accented errors, regardless of their relative typicality. The distinction between syntactic and semantic processing of foreign-accented speech is discussed.

title: Dataset from: A test of the reproductive assurance hypothesis in Ipomoea hederacea: does inbreeding depression counteract the benefits of self-pollination?

description: <strong>PREMISE: Darwin proposed that self-pollination in allegedly outcrossing species might act as a reproductive assurance mechanism when pollinators or mates are scarce; however, in natural populations, the benefits of selfing may be opposed by seed discounting and inbreeding depression. While empirical studies show variation among species and populations in the magnitude of reproductive assurance, little is known about the counterbalancing effects of inbreeding depression.</strong> <strong>METHODS: By comparing the female reproductive success of emasculated and open-pollinated flowers, we assessed the reproductive assurance hypothesis in two Mexican populations of <em>Ipomoea hederacea.</em> In one population we assessed temporal variation in reproductive assurance for three years. We evaluated inbreeding depression on seed production, seedling germination, and dry plant mass by contrasting self- and cross-hand pollination treatments in one population for two years.</strong> <strong> KEY RESULTS: The contribution of self-pollination to female reproductive success was high and consistent between populations, but there was variation in reproductive assurance across years. Inbreeding depression was absent in the early stages of progeny development, but there was a small negative effect of inbreeding in the probability of germination and the mass of adult progeny. </strong> <strong>CONCLUSIONS: Self-pollination provided significant reproductive assurance in <em>I. hederacea </em>but this contribution was variable across time. The contribution of reproductive assurance is probably reduced by inbreeding depression in later stages of progeny development, but this counter-effect was small in the study populations. This study supports the hypothesis that reproductive assurance with limited inbreeding depression is likely an important selective force in the evolution of self-pollination in the genus <em>Ipomoea</em>. </strong>

title: Pollen morphology applied to species delimitation of Turkish <i>Dianthus</i> L. (Caryophyllaceae)

description: The pollen morphology of 89 taxa belonging to the genus <i>Dianthus</i> L. is considered, utilizing light, scanning and transmission electron microscopy, and the taxa are compared based on their pollen characters. Of these, the pollen morphology of 73 taxa is reported for the first time. Pollen grains of <i>Dianthus</i> taxa are spheroidal, polypantoporate and 29.1–53 µm in size, and have 12–24 prominent or sunken apertures uniformly distributed on their surface. Spinules were present on all pollen grains, and puncta were seen in 73 taxa. The exine surface ornamentation can be divided into three types, namely microechinate, microechinate-punctate or microechinate-punctate-foveolate. Cluster analysis and principal component analysis demonstrate that the clustering of <i>Dianthus</i> taxa studied does not correlate well with the sectional classification; rather, the punctum number, the pollen diameter and the spinule number are the most valuable variables for separating the examined taxa.

title: Modern pollen and non-pollen palynomorphs along an altitudinal transect in Jammu and Kashmir (Western Himalaya), India

description: Pollen and non-pollen palynomorphs were analysed from 35 modern moss cushions collected along an altitudinal gradient (2225–2552 m a.s.l.) from the Baramulla District of Jammu and Kashmir State (Western Himalaya), India. The selected sampling altitude is at the elevation of appearance of blue pine (<i>Pinus wallichiana</i>) and West Himalayan spruce or morinda spruce (<i>Picea smithiana</i>). We used cluster analysis and principal component analysis (PCA) to reveal trends and characteristics in the modern pollen and non-pollen palynomorph composition within this zone. Tree taxa mainly correlated positively with the altitudinal gradient, i.e. tree pollen is more abundant at higher altitudes. The presence of West Himalayan spruce pollen increased significantly above 2490 m a.s.l., which coincides with its increased abundance in the area. Poaceae, Cerealia, Ranunculaceae, Caryophyllaceae, Asteroideae and Cichorioideae, indicating open land and human agricultural activities, are more characteristic of higher locations. Greater relative abundance of dung spores was characteristic of lower elevations, indicating human-related grazing activities. While tropical deciduous plants grow only at lower elevations away from the study area, their pollen was present at higher altitudes, suggesting long-distance pollen dispersal, beyond the growing localities.

title: Palaeoclimate reconstruction and age assessment of the Miocene flora from the Trwyn y Parc solution pipe complex of Anglesey, Wales, UK

description: The Trwyn y Parc solution pipes on the Isle of Anglesey, Wales, UK are one of only three onshore Miocene fossil flora bearing sites. Here, we revise the palynostratigraphy and present new palaeoclimate data for this geoheritage site. By comparison to palynological data from northern Europe the age has been refined from Miocene to Middle Miocene, possibly Langhian. This is confirmed by palaeoclimate reconstructions comparable to the German Middle Miocene, especially the Langhian after the Middle Miocene Climatic Optimum (MMCO). This new information not only confirms the regional importance of Trwyn y Parc, but shows it to be of national importance. Our findings show that this Regionally Important Geodiversity Site (RIGs) is of national importance as it is the oldest onshore fossiliferous Neogene deposit in the UK. Based on this, and the unique fossil flora preserved at Trwyn y Parc, the site has significant geoheritage value and should be upgraded to Geological Conservation Review (GCR) status and subsequently protected as a Site of Special Scientific Interest (SSSI).

title: Subtotal content and geochemical fractionation of potential toxic elements in agricultural soils from Mocorito River basin in NW Mexico: environmental and health implications

description: Agricultural soils were collected from Mocorito river basin, to determine potentially toxic elements (PTEs) subtotal concentrations and geochemical fractionation, and evaluate their environmental and health risks. All sites showed low As and Cr concentrations. Subtotal concentrations (mg/kg) ranged between 6.8 and 25.6 for As, 1.9 and 2.5 for Cd and 22.5 and 55.1 for Cr. These values were classified as moderately contaminated for As, while a considerable contamination was presented for Cd and Cr. Geochemical partitioning revealed that PTEs are strongly linked with residual phase. Arsenic was associated with amorphous Fe-oxyhydroxides. Ecotoxicological indices showed from low (As and Cr) to considerable (Cd) potential ecological risk factors; potential non-carcinogenic risks by As, Cd and Cr, and potential carcinogenic risks by As and Cr. Lithogenic and anthropogenic sources were identified. Arsenic and Cr showed lithogenic influence, while Cd increased, caused by nearby activities, representing an environmental and health risk.

title: Mass spectrometry based proteome profiling of the exhaled breath condensate for lung cancer biomarkers search

description: Lung cancer remains the most prevalent cause of cancer mortality worldwide mainly due to insufficient availability of early screening methods for wide-scale application. Exhaled breath condensate (EBC) is currently considered as one of the promising targets for early screening and is particularly attractive due to its absolutely noninvasive collection and possibility for long-term frozen storage. EBC proteome analysis can provide valuable information about the (patho)physiological changes in the respiratory system and may help to identify in time a high risk of lung cancer. Mass spectrometry (MS) profiling of EBC proteome seems to have no alternative in obtaining the most extensive data and characteristic marker panels for screening. This special report summarizes the data of several proteomic studies of EBC in normal and lung cancer (from 2012 to 2021, PubMed), focuses on the possible reasons for the significant discrepancy in the results, and discusses some aspects for special attention in further studies. The significant discrepancy in the results of various studies primarily highlights the need to create standardized protocols for the collection and preparation of EBC for proteomic analysis. The application of quantitative and targeted LC-MS/MS based approaches seems to be the most promising in further EBC proteomic studies.

title: Peptidomics and proteogenomics: background, challenges and future needs

description: With available genomic data and related information, it is becoming possible to better highlight mutations or genomic alterations associated with a particular disease or disorder. The advent of high-throughput sequencing technologies has greatly advanced diagnostics, prognostics, and drug development. Peptidomics and proteogenomics are the two post-genomic technologies that enable the simultaneous study of peptides and proteins/transcripts/genes. Both technologies add a remarkably large amount of data to the pool of information on various peptides associated with gene mutations or genome remodeling. Literature search was performed in the PubMed database and is up to date. This article lists various techniques used for peptidomic and proteogenomic analyses. It also explains various bioinformatics workflows developed to understand differentially expressed peptides/proteins and their role in disease pathogenesis. Their role in deciphering disease pathways, cancer research, and biomarker discovery using biofluids is highlighted. Finally, the challenges and future requirements to overcome the current limitations for their effective clinical use are also discussed.

title: A complete proteomic profile of human and bovine milk exosomes by liquid chromatography mass spectrometry

description: The present study investigates the proteomic content of milk-derived exosomes. A detailed description of the content of milk exosomes is essential to improve our understanding of the various components of milk and their role in nutrition. The exosomes used in this study were isolated as previously described and characterized by their morphology, particle concentration, and the presence of exosomal markers. Human and bovine milk exosomes were evaluated using Information-Dependent Acquisition (IDA) Mass Spectrometry. A direct comparison is made between their proteomic profiles. IDA analyses revealed similarities and differences in protein content. About 229 and 239 proteins were identified in the human and bovine milk exosome proteome, respectively, of which 176 and 186 were unique to each species. Fifty-three proteins were common in both groups. These included proteins associated with specific biological processes and molecular functions. Most notably, the 4 abundant milk proteins lactadherin, butyrophilin, perilipin-2, and xanthine dehydrogenase/oxidase were present in the top 20 list for both human and bovine milk exosomes. The milk exosome protein profiles we have provided are crucial new information for the field of infant nutrition. They provide new insight into the components of milk from both humans and bovines.
