Impact of the musculoskeletal apparatus of football players under psychological stress

Football is a popular sport with a large number of injuries, especially in the anterior cruciate ligament (ACL). Since ACL injury causes the most time lost from competition in soccer, it has influenced a strong research focus to determine the risk factors for injury. It is necessary to understand injury risk factors to identify the injury-prone athletes and to develop injury prevention plans. Most studies have addressed physical and biomechanical risk factors but nowadays psychological factors are mentioned as an important risk factor predictor [1]. The aim of this study was to investigate the influence of mental stress on knee injuries of football players. In order to analyse kinetics of football players, different vertical jumps and a math test were designed. Amateur football players (n=6), in the interest of comparing and finding patrons, performed the jumps once under non-stress condition and once under stress condition. The evaluated parameters were reaction forces, joint moments and muscle activity in the lower extremities. The simulations were done using biomechanical simulation software based on a motion capture data collection, and the obtained data was assigned with Vicon Nexus and Anybody to a musculoskeletal model. The psychological stress was carried out using BioGraph Infiniti, which can measure data such as temperature and skin conductance, EKG, etc. In order to assess and plot the results, a numerical program called Matlab was used. From the results these conclusions were proposed. Significant differences in knee joint between stress and no stress condition were found at ground impact during the first landings of the Drop Jumps. All 6 players except one had higher results in stress condition, especially in the right leg jumps. Even though the results from our study help to elucidate the mechanisms of psychological stress in male football players, a larger population of subjects should be used to complete and validate this work.Outgoin

On the Upper Ordovician unconformity in the Pyrenees: New evidence from the La Cerdanya area

In recent years, contradictory reports about whether or not an unconformity exists at the base of the Upper Ordovician succession of the Pyrenees have been made. In the Cerdanya area (Central Pyrenees), good outcrop evidence for this unconformity is displayed at the base of the Rabassa conglomerates. In this area, the Upper Ordovician rocks overlie a tilted Cambro-Ordovician sequence, displaying an angular unconformity and indicating a break in the stratigraphic series. Moreover, the existence of such an unconformity is supported by the distribution of Variscan minor structures, suggesting that the Cambro-Ordovician and the Upper Ordovician strata initially had different orientations before the main Variscan folding

Polysemy and brevity versus frequency in language

The pioneering research of G. K. Zipf on the relationship between word frequency and other word features led to the formulation of various linguistic laws. The most popular is Zipf's law for word frequencies. Here we focus on two laws that have been studied less intensively: the meaning-frequency law, i.e. the tendency of more frequent words to be more polysemous, and the law of abbreviation, i.e. the tendency of more frequent words to be shorter. In a previous work, we tested the robustness of these Zipfian laws for English, roughly measuring word length in number of characters and distinguishing adult from child speech. In the present article, we extend our study to other languages (Dutch and Spanish) and introduce two additional measures of length: syllabic length and phonemic length. Our correlation analysis indicates that both the meaning-frequency law and the law of abbreviation hold overall in all the analyzed languages

Empoderamiento de los ciudadanos desde la atención primaria: alfabetización sanitaria y prescripción web

La alfabetización y la prescripción web son claves para el empoderamiento de los paciente y deben promoverse desde la atención primaria. Los objetivos que se plantean son, entre otros, fomentar la proactividad y el diálogo entre los profesionales de la salud y la ciudadanía, y mejorar la calidad asistencial mediante un uso eficiente de los recursos

New anallytic approximations based on the Magnus expansion

The Magnus expansion is a frequently used tool to get approximate analytic solutions of time-dependent linear ordinary differential equations and in particular the Schrödinger equation in quantum mechanics. However, the complexity of the expansion restricts its use in practice only to the first terms. Here we introduce new and more accurate analytic approximations based on the Magnus expansion involving only univariate integrals which also shares with the exact solution its main qualitative and geometric propertie

Clinical and functional characteristics of individuals with alpha‑1 antitrypsin deficiency: EARCO international registry

Trial registration www. clini caltr ials. gov (ID: NCT04180319)Background Alpha-1 antitrypsin deficiency (AATD) is a rare disease that is associated with an increased risk of pulmonary emphysema. The European AATD Research Collaboration (EARCO) international registry was founded with the objective of characterising the individuals with AATD and investigating their natural history. Methods The EARCO registry is an international, observational and prospective study of individuals with AATD, defined as AAT serum levels < 11 μM and/or proteinase inhibitor genotypes PI*ZZ, PI*SZ and compound heterozygotes or homozygotes of other rare deficient variants. We describe the characteristics of the individuals included from February 2020 to May 2022. Results A total of 1044 individuals from 15 countries were analysed. The most frequent genotype was PI*ZZ (60.2%), followed by PI*SZ (29.2%). Among PI*ZZ patients, emphysema was the most frequent lung disease (57.2%) followed by COPD (57.2%) and bronchiectasis (22%). Up to 76.4% had concordant values of FEV1(%) and KCO(%). Those with impairment in FEV1(%) alone had more frequently bronchiectasis and asthma and those with impairment in KCO(%) alone had more frequent emphysema and liver disease. Multivariate analysis showed that advanced age, male sex, exacerbations, increased blood platelets and neutrophils, augmentation and lower AAT serum levels were associated with worse FEV1(%). Conclusions EARCO has recruited > 1000 individuals with AATD from 15 countries in its first 2 years. Baseline cross sectional data provide relevant information about the clinical phenotypes of the disease, the patterns of functional impairment and factors associated with poor lung function.GrifolsCSL BehringKamadapH PharmaTakeda to the European Respiratory Society (ERS)

Analyzing peptides and proteins by mass spectrometry: principles and applications in proteomics

Podeu consultar el llibre complet a: http://hdl.handle.net/2445/32166The study of proteins has been a key element in biomedicine and biotechnology because of their important role in cell functions or enzymatic activity. Cells are the basic unit of living organisms, which are governed by a vast range of chemical reactions. These chemical reactions must be highly regulated in order to achieve homeostasis. Proteins are polymeric molecules that have taken on the evolutionary process the role, along with other factors, of control these chemical reactions. Learning how proteins interact and control their up and down regulations can teach us how living cells regulate their functions, as well as the cause of certain anomalies that occur in different diseases where proteins are involved. Mass spectrometry (MS) is an analytical widely used technique to study the protein content inside the cells as a biomarker point, which describes dysfunctions in diseases and increases knowledge of how proteins are working. All the methodologies involved in these descriptions are integrated in the field called Proteomics
