Knee arthroplasty until age 60 : role of sports and other injuries
2019
BACKROUND: The primary aim of the study was to investigate how total knee arthroplasty (TKA) patients with underlying injuries differ in injury type and physical activity after the arthroplasty. METHODS: A questionnaire was sent to TKA patients, < 60 years at surgery, and knee injury as the cause of knee OA. The final study group consisted of 70 patients. RESULTS: Average age of patients at TKA was 51.8 years (Standard Deviation [SD] 5.2), and at follow-up 57.6 years (SD 6.5). Of the injuries, 26% were sports-related, 29% had occurred at work, 23% in traffic accidents, and 13% during leisure-time (no sports-related). Sports-related injuries had occurred at younger ages than others had (mean…
Assessing violence in the family : social work, courts, and discourses
2016
This article investigates social work, decision-making, and gendered violence in the family in Finland. Discourses on gendered violence in the family are compared in custody disputes, handled in district courts, and out-of-home placements, dealt with in administrative courts. Both data sets altogether include 237 cases. Proceedings in both courts share a legislative emphasis on the ‘child’s best interest’ principle, and both contexts also rely on documentation provided by social workers. The examination of the two studies is based on discourse analysis, through which we have identified hegemonic discourses that are active in both courts. The study found that violence was often disregarded o…
[60]Fullerene l -Amino Acids and Peptides: Synthesis under Phase-Transfer Catalysis Using a Phosphine–Borane Linker. Electrochemical Behavior
2017
International audience; A new method to link amino acid and peptide derivatives to [60]fullerene is described. It uses hydrophosphination with a secondary phosphine borane. First, the stereoselective synthesis of secondary phosphine borane amino acid derivatives was achieved by alkylation of phenylphosphine borane with gamma-iodo-alpha-amino ester reagents under phase transfer catalysis (PTC). Second, a sec-phosphine borane amino ester was saponified and coupled with alpha,gamma-diamino esters to afford the corresponding dipeptide derivatives in good yields. Finally, the hydrophosphination reaction of [60]fullerene by the sec-phosphine borane compounds was performed under PTC to obtain C-60…
Plausible Role of Estrogens in Pathogenesis, Progression and Therapy of Lung Cancer
2021
Malignant neoplasms are among the most common diseases and are responsible for the majority of deaths in the developed world. In contrast to men, available data show a clear upward trend in the incidence of lung cancer in women, making it almost as prevalent as breast cancer. Women might be more susceptible to the carcinogenic effect of tobacco smoke than men. Furthermore, available data indicate a much more frequent mutation of the tumor suppressor gene-p53 in non-small cell lung cancer (NSCLC) female patients compared to males. Another important factor, however, might lie in the female sex hormones, whose mitogenic or carcinogenic effect is well known. Epidemiologic data show a correlatio…
HDR-ARtiSt: a FPGA-based Smart Camera for High Dynamic Range color video from multiple exposures
2014
International audience; A camera is able to capture only a part of a high dynamic range scene information. The same scene can be fully perceived by the human visual system. This is true especially for real scenes where the difference in light intensity between the dark areas and bright areas is high. The imaging technique which can overcome this problem is called HDR (High Dynamic Range). It produces images from a set of multiple LDR images (Low Dynamic Range), captured with different exposure times. This technique appears as one of the most appropriate and a cheap solution to enhance the dynamic range of captured environments. We developed an FPGA-based smart camera that produces a HDR liv…
Koku un krūmu pavasara fenoloģisko fāžu izmaiņas Latvijā
2016
Bakalaura darba galvenais mērķis bija izanalizēt parastās ievas Padus racemosa ilgtermiņa tendences kopš 1927.gada, kā arī raksturot āra bērza Betula pendula, parastās lazdas Corylus avellana, baltalkšņa Alnus incana un parastā pīlādža Sorbus aucuparia pavasara fenoloģisko fāžu reģionālās izmaiņas Latvijā references periodā (1981.-2010.gads), izmantojot brīvprātīgo novērotāju vēsturiskos datus. Veikta digitālo fotoattēlu reģionāla analīze parastās ievas Padus racemosa fāzēm 2015. un 2016.gadā, izmantojot portāla Dabasdati.lv datu bāzi. Periodā no 1981.gada līdz 2010.gadam ir novērojams, ka pavasara fenoloģiskās fāzes iestājušās par 2-17 dienām agrāk, nekā laika posmā no 1971.-2000.gadam. Pa…
Influencia de la instrumentación con lima única en la calidad de la obturación del sistema de conductos radiculares mediante la técnica de condensaci…
2015
1.- Introducción: el principal objetivo en la terapia endodóncica es simplificar los procedimientos con completa seguridad y eficacia. Como alternativa a los sistemas rotatorios multilima, se crearon los sistemas de lima única de rotación alternante, con el fin de reducir la fatiga cíclica para disminuir el riesgo de fractura de los instrumentos, la deformidad del conducto radicular, rapidez y simplicidad en la conformación. Posteriormente, aparecieron sistemas de lima única de rotación continua que también aumentaron la rapidez y la simplicidad. Con la finalidad de analizar la capacidad de conformar los conductos radiculares de estos sistemas endodóncicos se realizó este estudio. 2.- Objet…
Application of the Chinese Version of the BIS/BAS Scales in Participants With a Substance Use Disorder: An Analysis of Psychometric Properties and Co…
2020
Carver and White developed the Behavioral Inhibition/Behavioral Activation Scales (the BIS/BAS Scales) based on Reinforcement Sensitivity Theory proposed by Gray. Subsequent studies proposed that substance abuse was closely related to Behavioral Inhibition System (BIS) and Behavioral Activation System (BAS). However, researches on the psychometric properties of the BIS/BAS scales in clinical samples are scarce. The present study was conducted to analyze the applicability of the BIS/BAS scales in a sample suffering from a substance use disorder (SUD) and undergoing treatment in compulsory detoxification institutions (n = 1117). Meanwhile, 822 community residents were selected for comparison.…
Competition, Gender Equality, and Doping in Sports in the Red Queen Effect Perspective
2022
The nature of sports is characterized by a strong competitive component that generates inequalities among athletes at different levels, specifically in relation to gender, technology, and doping. These inequalities can be represented according to the Red Queen effect perspective, which has been previously hypothesized in other competitive environments (evolutionary biology and economics, for instance). The Red Queen effect considers each competitive environment to require a constant effort to maintain a position of competitive advantage in order reach the best result possible. Therefore, the aim of the current paper is to provide an innovative perspective for the understanding of competitio…
Les PDU des années 2000/2010 et leurs discours : une analyse diachronique et politologique prenant appui sur la textométrie
2017
National audience; De nombreuses disciplines cherchent à comprendre les raisons profondes qui motivent la mise en place de politiques urbaines et les discours les accompagnant 1. Cela dit, ces travaux de recherche se heurtent souvent à des problèmes de méthodologie. En effet, les méthodes « classiques » que sont les entretiens avec les acteurs, le travail sur archives, la passation de questionnaires auprès d’acteurs ou encore les expérimentations présentent chacune de fortes limites par rapport à l’ambition scientifique d’une analyse distanciée et systématisée de l’action publique urbaine et de ses discours.
