Unidades terminológicas complejas de base deverbal: una propuesta de análisis de su proceso de formación

Con miras a contribuir a los estudios gramaticales de las unidades terminológicas complejas (UTC), la investigación doctoral cuyos resultados parciales se presentan en este trabajo tuvo por objetivo analizar el proceso de formación de UTC vehiculadas en el glosario de la Asociación Latinoamericana de Integración (ALADI). Partimos del presupuesto de que las UTC se originan a partir de oraciones reducidas por apagamientos, siguiendo los lineamientos de Auger (1978), y tuvimos como base la Teoría de la Gramátic a Funcional (TGF) de Dik (1989), destinada al análisis de estructuras oracionales de la lengua general, y la propuesta de adaptación de ese modelo presentada por Café (1999) para el reconocimiento de UTC. En este artículo, presentamos los resultados de los análisis de UTC de base deverbal obtenidos de una estructura subyacente oracional deducida de la definición propuesta en el glosario de la ALADI y del contrapunto de ese análisis con las reglas de reconocimiento de Café (1999). Los datos señalan que existe una inclinación a mantener el marco predicativo dikiano oracional en la estructura sintagmática, además de una tendencia a transformar los satélites oracionales en estructuras argumentales sintagmáticas

A acentuação de palavras lexicais acrescidas de enclíticas em latim

A IMPORTÂNCIA DA QUANTIDADE SILÁBICA EM LATIM: POEMAS DE HORÁCIO E MARCIAL

The aim of this paper is to analyse the behavior of enclitic stress in lexical words increasedwith the enclitic -que in Latin. We will present some notions about Latin accent, associated to theidea that the weight of the syllables is fundamental to the enclitic stress. Contrasting this theory tothe collected corpus in Horacios’s and Marcial’s poems, we perceive that, applying the theory ofmetrical phonology, it is possible to analyse the padrons of stress making use of two different patternsof metrical feet: moraic trochee and uneven trochee

Clonal chromosomal mosaicism and loss of chromosome Y in elderly men increase vulnerability for SARS-CoV-2

The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, COVID-19) had an estimated overall case fatality ratio of 1.38% (pre-vaccination), being 53% higher in males and increasing exponentially with age. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, we found 133 cases (1.42%) with detectable clonal mosaicism for chromosome alterations (mCA) and 226 males (5.08%) with acquired loss of chromosome Y (LOY). Individuals with clonal mosaic events (mCA and/or LOY) showed a 54% increase in the risk of COVID-19 lethality. LOY is associated with transcriptomic biomarkers of immune dysfunction, pro-coagulation activity and cardiovascular risk. Interferon-induced genes involved in the initial immune response to SARS-CoV-2 are also down-regulated in LOY. Thus, mCA and LOY underlie at least part of the sex-biased severity and mortality of COVID-19 in aging patients. Given its potential therapeutic and prognostic relevance, evaluation of clonal mosaicism should be implemented as biomarker of COVID-19 severity in elderly people. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, individuals with clonal mosaic events (clonal mosaicism for chromosome alterations and/or loss of chromosome Y) showed an increased risk of COVID-19 lethality

TRY plant trait database – enhanced coverage and open access

Plant traits - the morphological, anatomical, physiological, biochemical and phenological characteristics of plants - determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research spanning from evolutionary biology, community and functional ecology, to biodiversity conservation, ecosystem and landscape management, restoration, biogeography and earth system modelling. Since its foundation in 2007, the TRY database of plant traits has grown continuously. It now provides unprecedented data coverage under an open access data policy and is the main plant trait database used by the research community worldwide. Increasingly, the TRY database also supports new frontiers of trait‐based plant research, including the identification of data gaps and the subsequent mobilization or measurement of new data. To support this development, in this article we evaluate the extent of the trait data compiled in TRY and analyse emerging patterns of data coverage and representativeness. Best species coverage is achieved for categorical traits - almost complete coverage for ‘plant growth form’. However, most traits relevant for ecology and vegetation modelling are characterized by continuous intraspecific variation and trait–environmental relationships. These traits have to be measured on individual plants in their respective environment. Despite unprecedented data coverage, we observe a humbling lack of completeness and representativeness of these continuous traits in many aspects. We, therefore, conclude that reducing data gaps and biases in the TRY database remains a key challenge and requires a coordinated approach to data mobilization and trait measurements. This can only be achieved in collaboration with other initiatives

COVID-19 symptoms at hospital admission vary with age and sex: results from the ISARIC prospective multinational observational study

Background: The ISARIC prospective multinational observational study is the largest cohort of hospitalized patients with COVID-19. We present relationships of age, sex, and nationality to presenting symptoms. Methods: International, prospective observational study of 60 109 hospitalized symptomatic patients with laboratory-confirmed COVID-19 recruited from 43 countries between 30 January and 3 August 2020. Logistic regression was performed to evaluate relationships of age and sex to published COVID-19 case definitions and the most commonly reported symptoms. Results: ‘Typical’ symptoms of fever (69%), cough (68%) and shortness of breath (66%) were the most commonly reported. 92% of patients experienced at least one of these. Prevalence of typical symptoms was greatest in 30- to 60-year-olds (respectively 80, 79, 69%; at least one 95%). They were reported less frequently in children (≤ 18 years: 69, 48, 23; 85%), older adults (≥ 70 years: 61, 62, 65; 90%), and women (66, 66, 64; 90%; vs. men 71, 70, 67; 93%, each P < 0.001). The most common atypical presentations under 60 years of age were nausea and vomiting and abdominal pain, and over 60 years was confusion. Regression models showed significant differences in symptoms with sex, age and country. Interpretation: This international collaboration has allowed us to report reliable symptom data from the largest cohort of patients admitted to hospital with COVID-19. Adults over 60 and children admitted to hospital with COVID-19 are less likely to present with typical symptoms. Nausea and vomiting are common atypical presentations under 30 years. Confusion is a frequent atypical presentation of COVID-19 in adults over 60 years. Women are less likely to experience typical symptoms than men
