Festuca dertosensis (Poaceae), an overlooked fescue from the NE Iberian Peninsula

11 p., mapas, fot., il.A new species of Festuca L. (Poaceae) is described from the southern mountains of Tarragona (Catalonia, Spain). The new taxon belongs to the F. rubra aggregate, and superficially resembles plants of the F. trichophylla group. Its leaf anatomy, however, suggests a closer relationship with F. rubra and, in particular, F. heterophylla. Although sharing some features with F. paucispicula, a sympatric taxon, there are sufficient differences to warrant its separation from this local endemic. A comparative table and key are provided to assist in the identification of this overlooked fescue, and its relationship to other species present in the area is discussed, with special attention paid to species sharing a similar distribution. Mitosis studies have been carried out to determine the chromosome number, and the results suggest a decaploid, with a chromosome number of 2n = c. 70.Peer reviewe

Effects of flooding on mental health: a case-control study

3rd International Congress on Neurobiology, Psychopharmacology & Treatment guidance (May 30th - June 2nd, 2013)Background: Post-disaster mental health problems may affect population in different ways. Population exposure to a natural disaster has been associated with psychological distress, in particular, in the development of Posttraumatic Stress Disorder (PTSD). Most people experience distress after their exposure to an extreme event. For people with good psychosocial resilience and access to social support, mental health problems can be relatively less important since supporting relationships and inner capabilities may begin the adaptation processes. Mental disorders occur often, but less commonly than dis-tress, and in some cases they may require intensive and long term continuing interventions and treatment

Perspectiva de la Felicidad laboral en el Contexto Latinoamericano

Currently, organizations impact people's lives and to achieve delight with life it is necessary to be happy at work, as it is a phenomenon that characterizes every individual. However, various studies have shown that when societies present or experience high rates of economic growth, people, thanks to their income levels, experience an increase in happiness. Thus, the main objective of this article was to analyze the perspective of work happiness in the Latin American context, based on authors such as Pizarro, Rojas, Vera (2021), Ludeña, Tobar, Ahumada (2021), Sánchez (2018), among others. The investigation corresponds to a documentary review. It is concluded that happiness is not built on an individual level, since the happiness of one group cannot be the misery of others. In this sense, social justice is very necessary. However, it is unavoidable to emphasize that human beings are not willing to renounce such an experience. However, it is useful for companies to allow their workers a job tranquility focused on incentives, since economic growth affects the happiness of workers.Actualmente, las organizaciones impactan la vida de las personas y para alcanzar el deleite con la vida se requiere ser feliz en el trabajo, pues es un fenómeno que caracteriza a todo individuo. No obstante, diversos estudios han demostrado que cuando las sociedades presentan o experimentan altas tasas de crecimiento económico, las personas gracias a sus niveles de ingresos experimentan un incremento de felicidad. Así pues, el presente artículo tuvo como objetivo central analizar la perspectiva de la felicidad laboral en el contexto latinoamericano, basándose en autores como Pizarro, Rojas, Vera (2021), Ludeña, Tobar, Ahumada (2021), Sánchez (2018), entre otros. La investigación corresponde a una revisión documental. Se concluye que la felicidad no se construye en un plano individual, pues la felicidad de un grupo no puede ser la desdicha de otros. En este sentido, la justicia social es muy necesaria. Más sin embargo se hace ineludible resaltar que el ser humano no está dispuesto a renunciar a tal experiencia. No obstante, resulta útil que las empresas permitan a sus trabajadores una tranquilidad laboral enfocada en incentivos, pues el crecimiento económico incide en la felicidad de los trabajadores

A worldwide molecular phylogeny and classification of the leafy spurges, Euphorbia subgenus Esula (Euphorbiaceae)

The leafy spurges, Euphorbia subg. Esula, make up one of four main lineages in Euphorbia. The subgenus comprises about 480 species, most of which are annual or perennial herbs, but with a small number of dendroid shrubs and nearly leafless, pencilâ stemmed succulents as well. The subgenus constitutes the primary northern temperate radiation in Euphorbia. While the subgenus is most diverse from central Asia to the Mediterranean region, members of the group also occur in Africa, in the Indoâ Pacific region, and in the New World. We have assembled the largest worldwide sampling of the group to date (273 spp.), representing most of the taxonomic and geographic breadth of the subgenus. We performed phylogenetic analyses of sequence data from the nuclear ribosomal ITS and plastid ndhF regions. Our individual and combined analyses produced wellâ resolved phylogenies that confirm many of the previously recognized clades and also establish a number of novel groupings and placements of previously enigmatic species. Euphorbia subg. Esula has a clear Eurasian center of diversity, and we provide evidence for four independent arrivals to the New World and three separate colonizations of tropical and southern Africa. One of the latter groups further extends to Madagascar and New Zealand, and to more isolated islands such as Réunion and Samoa. Our results confirm that the dendroid shrub and stemâ succulent growth forms are derived conditions in E. subg. Esula. Stemâ succulents arose twice in the subgenus and dendroid shrubs three times. Based on the molecular phylogeny, we propose a new classification for E. subg. Esula that recognizes 21 sections (four of them newly described and two elevated from subsectional rank), and we place over 95% of the accepted species in the subgenus into this new classification.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/146962/1/tax6221.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/146962/2/tax6221-sup-004-pdf.pd

COVID-19: Some unresolved issues

Two years after the COVID-19 pandemic, many uncertainties persist about the causal agent, the disease and its future. This document contains the reflection of the COVID-19 working group of the Official College of Physicians of Madrid (ICOMEM) in relation to some questions that remain unresolved. The document includes considerations on the origin of the virus, the current indication for diagnostic tests, the value of severity scores in the onset of the disease and the added risk posed by hypertension or dementia. We also discuss the possibility of deducing viral behavior from the examination of the structure of the complete viral genome, the future of some drug associations and the current role of therapeutic resources such as corticosteroids or extracorporeal oxygenation (ECMO). We review the scarce existing information on the reality of COVID 19 in Africa, the uncertainties about the future of the pandemic and the status of vaccines, and the data and uncertainties about the long-term pulmonary sequelae of those who suffered severe pneumonia.post-print462 K

New variants of SARS-CoV-2

The emergence and spread of new variants of SARS-CoV-2 has produced enormous interest due to their possible implication in the improved transmissibility of the virus, their consequences in the individual evolution of the infection, as well as in the possible escape from the immunity generated by the current vaccines. The variants that attract most attention are those of public health concern, including B.1.1.7 (UK), P.1 (Brazilian) and B.1.351 (South African). This list is extended by the variants of interest that emerge and are expanding in certain countries but are found sporadically in others, such as B.1.427 and B.1.429 (Californians) or B.1.617 (Indian). Whole genome sequencing or strategies specifically targeting the spicule gene are used in the microbiology laboratories for characterization and detection. The number of infected individuals, the sanitary situation of each country, epidemiological measures and vaccination strategies influence its dispersion and new variants are expected to emerge. This emergence can only be avoided today by increasing the vaccinated population in all countries and by not relaxing epidemiological containment measures. It is not excluded that in the future it will be necessary to revaccinate against new variants.post-print186 K

Persistence and viability of SARS-CoV-2 in primary infection and reinfections

Since the beginning of the SARS-CoV-2 epidemic, virus isolation in the infected patient was only possible for a short period of time and it was striking that this occurred constantly and did not provide guidance on the clinical course. This fact led to confusion about the efficacy of some of the drugs initially used, which seemed to have a high efficiency in viral clearance and proved ineffective in modifying the course of the disease. The immune response also did not prove to be definitive in terms of evolution, although most of the patients with very mild disease had a weak or no antibody response, and the opposite was true for the most severe patients. With whatever the antibody response, few cases have been re-infected after a first infection and generally, those that have, have not reproduced a spectrum of disease similar to the first infection. Among those re-infected, a large number have been asymptomatic or with very few symptoms, others have had a moderate picture and very few have had a poor evolution. Despite this dynamic of rapid viral clearance, laboratory tests were still able to generate positive results in the recovery of genomic sequences and this occurred in patients who were already symptom-free, in others who were still ill and in those who were very seriously ill. There was also no good correlate. For this reason and with the perspective of this year and the half of pandemic, we compiled what the literature leaves us in these aspects and anticipating that, as always in biology, there are cases that jump the limits of the general behavior of the dynamics of infection in genera
