The link between mitochondrial DNA hypervariable segment I heteroplasmy and ageing among genetically unrelated Latvians
2011
International audience; Various studies have demonstrated that mitochondrial DNA (mtDNA) heteroplasmy tends to increase with age and that the observed frequency of heteroplasmy among populations mostly depends on the way it is measured. Therefore, we investigated age-related association on the presence of mtDNA heteroplasmy within the hypervariable segment 1 (HVS-I) in a selected study group. The study group consisted of 300 maternally unrelated Latvians ranging in age from 18 to over 90years. To determine the optimal method for mtDNA heteroplasmy detection, three approaches were used: (i) SURVEYORTM Mutation Detection Kit, (ii) sequencing and (iii) denaturing gradient-gel electrophoresis (…
Mood, cognitive structuring and medication adherence
2018
A study with a placebo was conducted. Healthy university students were given a placebo and were told to make one pill every day for a week. Participants were informed that the medicine improved mood. The extent to which they conformed to this instruction was treated as an index of compliance. Our results show that for women, but not for men, positive mood and cognitive structuring or negative mood and lack of cognitive structuring significantly predicted participants' compliance. A new model of medication adherence, based on the role of the patient's mood and cognitive structuring processes in decision making is presented in the paper.
Exposure therapy changes dysfunctional evaluations of somatic symptoms in patients with hypochondriasis (health anxiety). A randomized controlled tri…
2015
Dysfunctional evaluations of somatic symptoms are considered a central factor in maintaining hypochondriasis. The aim of the current study was to investigate whether exposure therapy (ET) without cognitive restructuring is sufficient to change dysfunctional evaluations of somatic symptoms. The current study was based on a randomized controlled trial and compared patients with hypochondriasis (N=73) receiving ET or cognitive therapy (CT) to a wait list (WL) control group. In both the ET and CT groups, dysfunctional symptom evaluations changed significantly compared with the WL group. No differences between the ET and CT groups emerged. The relationship between the treatment condition (active…
Comparison of three methods for evaluation of work postures in a truck assembly plant
2017
International audience; This study compared the results of three risk assessment tools (self-reported questionnaire, observational tool, direct measurement method) for the upper limbs and back in a truck assembly plant at two cycle times (11 and 8 min). The weighted Kappa factor showed fair agreement between the observational and direct measurement method for the arm (0.39) and back (0.47). The weighted Kappa factor for these methods was poor for the neck (0) and wrist (0) but the observed proportional agreement (P-o) was 0.78 for the neck and 0.83 for the wrist. The weighted Kappa factor between questionnaire and direct measurement showed poor or slight agreement (0) for different body seg…
Relationship between Burnout and Body Mass Index in Senior and Middle Managers from the Mexican Manufacturing Industry
2018
This research relates Burnout Syndrome (BS) with the Body Mass Index (BMI) among middle and senior managers of the Mexican manufacturing industry. Even though BS incidence is high in the Mexican industrial population, few systematic studies have explored BS and its relationship with other health problems, such as obesity. The goal of this research is to determine the relationship between BS and the BMI in employees with normal weight, overweight, and obesity. We present three structural equation models to relate BS and the BMI. The BMI ranges were determined according to the parameters (normal weight, overweight, and obesity) proposed by the World Health Organization (WHO). The sample inclu…
Primeros hallazgos de Aedes (Stegomyia) albopictus (Skuse, 1894) en la provincia de Valencia, España
2013
First findings of Aedes (Stegomyia) albopictus (Skuse, 1894) in the province of Valencia, Spain Framed within the project "Entomological surveillance at airports and ports against vectors of imported infectious diseases, and sur- veillance of potential native vectors of these diseases", on Septem- ber 2011 Aedes albopictus (Diptera, Culicidae) is reported for the first time in the province of Valencia in the coastal municipalities of Sueca, Cullera and Gandia, using oviposition traps.
Contribution to the knowledge of the mosquitoes in the Devesa of Racó de l Olla, Albufera Natural Park of Valencia (Spain)
2017
[ES] Se presenta una recopilación de los resultados de varios proyectos, desarrollados entre los años 2004 y 2015, sobre la presencia de los mosquitos de la familia Culicidae en el entorno de la Devesa y el Racó de l¿Olla del Parque Natural de l¿Albufera de Valencia (España). Se registró un total de 10 especies pertenecientes a cinco géneros (Aedes, Coquillettidia, Culex, Culiseta y Ochlerotatus), alguno de estos muy característicos de los ambientes donde fueron recolectados. Se tratan diferentes aspectos sobre la diversidad de culícidos, así como del interés ecológico y sanitario de la presencia de los mismos. Destacamos la existencia de la especie Aedes albopictus (Skuse, 1894) en un espa…
Effect of biomass features on oxygen transfer in conventional activated sludge and membrane bioreactor systems
2019
Abstract The aim of the present study was to compare the oxygen transfer efficiency in a conventional activated sludge and a membrane bioreactor system. The oxygen transfer was evaluated by means of the oxygen transfer coefficient and α-factor calculation, under different total suspended solids concentration, extracellular polymeric substances, sludge apparent viscosity and size of the flocs. The oxygen transfer coefficient and α-factor showed an exponential decreasing trend with total suspended solid, with a stronger oxygen transfer coefficient dependence in the conventional activated sludge compared to the membrane bioreactor. It was noted that the oxygen transfer coefficient in the conve…
An agent-based model to support the preliminary design and operation of heating and power grids with cogeneration units and photovoltaic panels in de…
2022
The increase in the energy demands of residential neighborhoods constitutes a huge challenge to be faced. A viable option lies in the insertion of both renewable energy production systems and cogeneration units within urban territories. On-site production allows for the satisfaction of the heating and electrical demands of end-users and favors the distribution of produced energy within the neighborhood, especially under the regulatory framework of energy communities. This paper proposes a tool to model heating and electricity networks integrated with cogeneration units and PV panels installed in urban areas. The tool accounts for the following possibilities: (i) energy flow management and p…
Evaluation of aging behavior under salt-fog spray conditions of green sandwich structures
2018
In this paper, the aging resistance of sandwich structures made with cork agglomerate as core and flax-reinforced polymeric laminates as face sheets was investigated for the first time. In order to evaluate their durability in a hostile environment, a sandwich plate was manufactured by vacuum bagging technique and aged under salt-fog spray conditions, according to ASTM B 117 standard. The evolution of the sandwich mechanical properties during the aging exposition was analyzed by carrying out quasi-static flexural tests and Charpy impact tests both on unaged specimens and on specimens aged for 10, 25, and 60 days, respectively. The quasi-static experimental results showed that despite the sa…
