Occupational stress among Brazilian oral-maxillofacial surgeons
2009
Purpose: The aim of the present study was to assess the stress level of oral-maxillofacial surgeons, based on the Demand-Control Model. Methods: A cross-sectional study was carried out with 128 oral-maxillofacial surgeons who participated in the Brazilian Congress of Oral-Maxillofacial Surgery held in the city of Florianópolis, State of Santa Catarina, Brazil. Data was obtained using a questionnaire that incorporated the Demand-Control Model (Job Content Questionnaire), which evaluates psychosocial experiences at work. Information on age, gender and professional qualification was also collected. The data was displayed in contingency tables. The following statistical tests were used with a 5…
Fall incidence in frail older women after individualized visual feedback-based balance training.
2003
<i>Background:</i> The knowledge concerning balance training actually lowering fall rates among frail older persons is limited. <i>Objective:</i> The aim of this study was to examine the effects of a 4-week individualized visual feedback-based balance training on the fall incidence during 1-year follow-up among frail older women living in residential care. <i>Methods:</i> Twenty-seven older women from 2 residential care homes were randomized into exercise (n = 20) and control (n = 7) groups. Balance measurements were carried out before and after a 4-week training period and falls were monitored by monthly diaries for 1 year. An interview about fear of fal…
Variability of Spanish adolescents’ physical activity patterns by seasonality, day of the week and demographic factors
2008
Abstract In this study, we examined the variability of physical activity (and inactivity) patterns in relation to gender, age, type of school, day of the week, and season of the year among a sample of Spanish adolescents aged 12–16 years. Levels of physical activity engagement, “who” was active/inactive, and “when” they were active/inactive were addressed. A Spanish translation and modification of Cale's Four by One-Day Physical Activity Questionnaire was administered by interviewer to 323 participants to measure estimated energy expenditure. Activity was assessed for two weekdays and two weekend days on two occasions during the autumn and two occasions during the winter. In an effort to be…
Oral health care activities performed by caregivers for institutionalized elderly in Barcelona-Spain
2013
Objectives: To describe the frequency of brushing teeth and cleaning of dentures, performed by caregivers, for institutionalized elderly people. Methods: A cross-sectional study in a sample of 196 caregivers of 31 health centers in Barcelona. The dependent variables were frequency of dental brushing and frequency of cleaning of dentures of the elderly by caregivers. The independent variables were characteristics of caregivers and institutions. We performed bivariate and multivariate descriptive analyses. Robust Poisson regression models were fitted to determine factors associated with the dependent variables and to assess the strength of the association. Results: 83% of caregivers were wome…
Reliability and Validity of the Tilburg Frailty Indicator in 5 European Countries
2020
OBJECTIVES: To assess the internal consistency, convergent and divergent validity, and concurrent validity of the Tilburg Frailty Indicator (TFI) within community-dwelling older people in Spain, Greece, Croatia, the Netherlands, and the United Kingdom.DESIGN: Cross-sectional study.SETTING: Primary care and community settings.PARTICIPANTS: In total, 2250 community-dwelling older people (60.3% women; mean age = 79.7 years; standard deviation = 5.7).METHODS: We assessed the reliability and validity of the full TFI as well as its physical, psychological, and social domains. Baseline data of the Urban Health Centers Europe project were used. The internal consistency was assessed with the Cronbac…
Optimizing and comparing gap-filling techniques using simulated NDVI time series from remotely sensed global data
2019
Abstract NDVI (Normalized Difference Vegetation Index) time series usually suffer from remaining cloud presence, even after data pre-processing. To address this issue, numerous gap-filling (or reconstruction) techniques have been developed in the literature, although their comparison has mainly been local to regional, with only two global studies to date, and has led to sometimes contradictory results. This study builds on these different comparisons, by testing different parameterizations for five NDVI temporal profile reconstruction techniques, namely HANTS (Harmonic Analysis of Time Series), IDR (iterative Interpolation for Data Reconstruction), Savitzky-Golay, Asymmetric Gaussian and Do…
Cohen syndrome is associated with major glycosylation defects
2014
International audience; Cohen syndrome (CS) is a rare autosomal recessive disorder with multisytemic clinical features due to mutations in the VPS13B gene, which has recently been described encoding a mandatory membrane protein involved in Golgi integrity. As the Golgi complex is the place where glycosylation of newly synthesized proteins occurs, we hypothesized that VPS13B deficiency, responsible of Golgi apparatus disturbance, could lead to glycosylation defects and/or mysfunction of this organelle, and thus be a cause of the main clinical manifestations of CS. The glycosylation status of CS serum proteins showed a very unusual pattern of glycosylation characterized by a significant accum…
Keggin heteropolyacid supported on TiO2 used in gas-solid (photo)catalytic propene hydration and in liquid-solid photocatalytic glycerol dehydration
2017
Abstract (Photo)catalytic propene hydration to 2-propanol and glycerol dehydration to acrolein were carried out by using Keggin heteropolyacids (HPAs) supported on TiO 2 . Binary materials have been prepared by impregnation of H 3 PW 12 O 40 , H 3 PMo 12 O 40 and H 4 SiW 12 O 40 , on TiO 2 Evonik P25. Moreover, a binary material consisting of H 4 SiW 12 O 40 and TiO 2 was prepared via a hydrothermal treatment and tested for the same reactions. All the materials were characterized by X-ray diffraction (XRD), scanning electron microscopy observations (SEM) coupled with energy dispersive X-ray (EDX) measurements, diffuse reflectance spectroscopy (DRS), Raman spectroscopy and Fourier transform …
Modeling of the process of moisture loss during the storage of dried apricots
2011
[EN] Moisture content is a reference parameter for dried food because the growth of most microorganisms is inhibited below certain water activity levels. In addition, it has a determining influence on the evolution of important parameters, such as color and flavor, and on other properties and deterioration reactions, such as texture, oxidation processes and nutritional value. During the storage of some dried fruits, moisture is produced due to Maillard reactions and exchanged with the surrounding environment through the packaging. The evolution of dried foods during their shelf life depends on the storage conditions. The aim of this study is to analyze the evolution of the moisture content …
Retention mechanisms for ER and Golgi membrane proteins
2014
Unless there are mechanisms to selectively retain membrane proteins in the endoplasmic reticulum (ER) or in the Golgi apparatus, they automatically proceed downstream to the plasma or vacuole membranes. Two types of coat protein complex I (COPI)-interacting motifs in the cytosolic tails of membrane proteins seem to facilitate membrane retention in the early secretory pathway of plants: a dilysine (KKXX) motif (which is typical of p24 proteins) for the ER and a KXE/D motif (which occurs in the Arabidopsis endomembrane protein EMP12) for the Golgi apparatus. The KXE/D motif is highly conserved in all eukaryotic EMPs and is additionally present in hundreds of other proteins of unknown subcellu…
