Measuring mutagenicity in ecotoxicology: A case study of Cd exposure in Chironomus riparius.
2021
Abstract Existing mutagenicity tests for metazoans lack the direct observation of enhanced germline mutation rates after exposure to anthropogenic substances, therefore being inefficient. Cadmium (Cd) is a metal described as a mutagen in mammalian cells and listed as a group 1 carcinogenic and mutagenic substance. But Cd mutagenesis mechanism is not yet clear. Therefore, in the present study, we propose a method coupling short-term mutation accumulation (MA) lines with subsequent whole genome sequencing (WGS) and a dedicated data analysis pipeline to investigate if chronic Cd exposure on Chironomus riparius can alter the rate at which de novo point mutations appear. Results show that Cd exp…
Epileptiform activity in the acute phase of stroke predicts the outcomes in patients without seizures
2023
Background and purposeThe abnormalities in EEG of stroke-patients increase the risk of epilepsy but their significancy for poststroke outcome is unclear. This presented study was aimed at determining the prevalence and nature of changes in EEG recordings from the stroke hemisphere and from the contralateral hemisphere. Another objective was to determine the significance of abnormalities in EEG in the first days of stroke for the post-stroke functional status on the acute and chronic phase of disease.MethodsIn all qualified stroke-patients, EEG was performed during the first 3 days of hospitalization and at discharge. The correlation between EEG abnormalities both in the stroke hemisphere an…
Effects of combined hormone replacement therapy or its effective agents on the IGF-1 pathway in skeletal muscle.
2010
Objectives To investigate the effects of combined hormone replacement therapy (HRT) and its effective agents on the IGF-1 signaling pathway. Design and methods To examine the effects of HRT on skeletal muscle in vivo, we utilized pre- and post-intervention samples from a randomized double blinded trial with 50–57-year-old women. The intervention included the year-long use of either HRT preparation (2 mg 17β-estradiol, E2; 1 mg norethisterone acetate, NETA, n = 10) or placebo (CO, n = 9). Microarray technology and quantitative PCR (qPCR) were used to study the expression of insulin-like growth factor I (IGF-1) and its splice variants as well as IGF-1 receptor, Akt1, mTOR, FOXO1, FOXO3, atrog…
Iän ja hormonikorvaushoidon yhteys tulehdustekijöihin sekä kehon koostumukseen postmenopausaalisilla naisilla
2010
Vahvat ja hyvinvoivat lihakset ovat yksi tärkeimmistä ihmisen terveyttä ja hyvää elämänlaatua ylläpitävistä tekijöistä. Ihmisen ikääntyessä lihasproteiinien hajotus tehostuu johtaen lihassäikeiden pienenemiseen ja niiden määrän vähenemiseen. Tämä puolestaan johtaa lihasten massan, voiman ja toimintakyvyn heikkenemiseen. Kroonisen matalaintensiteettisen tulehduksen uskotaan olevan merkittävimpiä lihasproteiinien hajotusta lisääviä tekijöitä. Matalaintensiteettinen tulehdus on usein yhteydessä korkeaan ikään ja se ilmenee seerumin kohonneina sytokiinitasoina. Sytokiinien lisääntymiseen vaikuttavat muun muassa immuunijärjestelmän heikentyminen, oksidatiivinen stressi ja rasvakudoksen lisääntym…
Ocena wiarygodności internetowych serwisów wybranych polskich wyższych uczelni niepublicznych
2019
Celem artykułu jest dokonanie i przedstawienie oceny wiarygodności internetowych serwisów wybranych polskich wyższych uczelni niepublicznych. Koncepcja, metody badań: Sięgając do definicji terminów związanych z pojęciem wiarygodność odniesiono je do serwisów internetowych. Na tej podstawie stworzono konceptualne ramy oceny wiarygodności dla takich serwisów. Ramy te posłużyły do oceny wiarygodności internetowych serwisów wybranych wyższych uczelni niepublicznych w Polsce z wykorzystaniem metody sondażowej i oryginalnego narzędzia. Ranking wiarygodności badanych serwisów internetowych utworzono wykorzystując metodę TOPSIS. Wyniki i wnioski: W artykule pokazano, że zestaw cech i kryteriów używ…
The Influence of Student Abilities and High School on Student Growth: A Case Study of Chinese National College Entrance Exam
2019
Enabled by available educational data and data mining techniques, educational data analysis has become a hot topic. Current researches mainly focus on the prediction of problems and performance rather than revealing the underlying causal relationships. Based on a unique exam data, we extracted the abilities of examinee from HSEE (High School Entrance Exam) based on the knowledge of educational experts, then we measured student growth from middle school to high school in total score and subject scores. We studied the impact of high school ranking and student abilities of HSEE on student growth by multiple linear regression model, in which high school ranking is divided into 5 levels, Level 1…
Evaluación y clasificación de las revistas científicotécnicas españolas de Ciencias de la Actividad Física y el Deporte
2008
En este artículo se evalúan y clasifican las revistas españolas de Ciencias de la Actividad Física y el Deporte (CCAFD), atendiendo a su calidad global. Para ello se aplica un modelo de evaluación, validado con anterioridad, que combina 23 indicadores relativos a diferentes características de las revistas (formales, de contenido científico y difusión). De esta manera pueden clasificarse las publicaciones periódicas en cuatro categorías de calidad: ‘muy alta’, ‘alta’, ‘media’ y ‘baja’. Los resultados indican que ninguna de las 28 publicaciones existentes alcanza la categoría superior, el 25% obtiene una calidad ‘alta’, el 50% una calidad ‘media’ y otro 25% una calidad ‘baja’. Aunque se obser…
Assessment and classification of Spanish scientific-technical journals of Physical Activity and Sport Sciences
2008
This paper evaluates and classifies Spanish Physical Activity and Sports Science journals according to their overall quality. A previously validated assessment model combining 23 indicators of style, scientific content and diffusion characteristics was used for this purpose. This model classifies journals into four quality categories: ‘very high’, ‘high’, ‘medium’ and ‘low’. None of the 28 journals studied fell into the top category, 25% fell into the ‘high’ category, 50% into the ‘medium’ category, and the remaining 25% into the ‘low’ category. A general improvement was observed compared to previous assessments of these journals, although deficient standardization and a non frequent use of…
