Degradation of Lincomycin in aqueous medium: coupling of solar photocatalysis and membrane separation

2005

Abstract The photocatalytic oxidation of a common antibiotic, the lincomycin was carried out in aqueous suspensions of polycrystalline TiO 2 Degussa P25 irradiated by sunlight. In order to improve the performance of the lincomycin degradation a hybrid system consisting of a solar photoreactor with the photocatalyst in suspension coupled with a membrane module, used to confine both photocatalyst and pollutants in the reaction environment, was tested. A preliminary study was carried out in order to determine some kinetics parameters of the drug photodegradation. The influence of initial substrate concentration on the lincomycin photooxidation rate was investigated. The photooxidation rate fol…

Subjective stress, objective heart rate variability-based stress, and recovery on workdays among overweight and psychologically distressed individual…

2015

Background: The present study aimed to investigate how subjective self-reported stress is associated with objective heart rate variability (HRV)-based stress and recovery on workdays. Another aim was to investigate how physical activity (PA), body composition, and age are associated with subjective stress, objective stress, and recovery. Methods: Working-age participants (n = 221; 185 women, 36 men) in this cross-sectional study were overweight (body mass index, 25.3-40.1 kg/m(2)) and psychologically distressed (>= 3/12 points on the General Health Questionnaire). Objective stress and recovery were based on HRV recordings over 1-3 workdays. Subjective stress was assessed by the Perceived St…

Cold Exposure Affects Lipid Metabolism, Fatty Acids Composition and Transcription in Pig Skeletal Muscle

2021

Cold exposure promotes glucose oxidation and modulates the lipid metabolism in adipose tissue, but it is still not fully clear whether cold exposure could affect meat quality and fatty acid metabolism in skeletal muscle of pig in vivo. Here, we kept finishing pigs under cold or room temperature overnight and determined the effects of cold exposure on meat quality, fatty acids composition and transcriptional changes in skeletal muscle of pigs. We found that cold exposure significantly reduced the meat colour24 h and pH24 h, without affecting carcass characteristics and other meat quality traits. Considerable changes were found in the proportions of individual fatty acids and the total conten…

Assessment of occupational exposure to pesticides in Spain through a job-exposure matrix (MatEmESp, 1996-2005)

2014

Introducción: La exposición laboral a plaguicidas ha sido asociada a numerosos problemas de salud. Sin embargo, la información sobre la exposición de los trabajadores afectados en España es escasa y dispersa. Objetivos: El objetivo de este trabajo fue estimar el nivel y la prevalencia de la exposición laboral a plaguicidas en España para el periodo 1996-2005, como parte del proyecto de construcción de la matriz empleo-exposición española, MatEmESp. Métodos: El establecimiento de las ocupaciones expuestas, los agentes de referencia y las estimaciones de exposición se basó en información de otras matrices, datos de evaluaciones de riesgos en empresas españolas y revisión de la bibliografía.

Desarrollo de nuevas estrategias analíticas basadas en la espectrometría de masas de alta resolución (HRMS) para el control de plaguicidas y sus meta…

2018

El uso de plaguicidas en la agricultura, permiten aumentar el rendimiento de las cosechas, evitando pérdidas debidas a animales, plantas y microorganismos que pueden llegar a tener un efecto negativo sobre la producción agrícola. Así, debido a su uso intensivo en las prácticas agrícolas, los plaguicidas pueden contaminar los distintos compartimentos ambientales (agua, suelo, aire, etc). Actualmente, aproximadamente 500 sustancias activas están autorizadas por la Unión Europea para ser aplicadas a los distintos cultivos siguiendo la Regulación CE 1107/2009. Una parte de los plaguicidas se emiten a la atmósfera durante y después de su aplicación. En la atmósfera, los plaguicidas pueden llegar…

Rhynchophorus ferrugineus attack affects a group of compounds rather than rearranging Phoenix canariensis metabolic pathways.

2016

The red palm weevil (RPW; Rhynchophorus ferrugineus) is spreading worldwide and severely harming many palm species. However, most studies on RPW focused on insect biology, and little information is available about the plant response to the attack. In the present experiment, we used metabolomics to study the alteration of the leaf metabolome of Phoenix canariensis at initial (1st stage) or advanced (2nd stage) attack by RPW compared with healthy (unattacked) plants. The leaf metabolome significantly varied among treatments. At the 1st stage of attack, plants showed a reprogramming of carbohydrate and organic acid metabolism; in contrast, peptides and lipid metabolic pathways underwent more c…

Laboratory evaluation of the effect of plant extracts on Tetranychus urticae Koch (Acariformes, Tetranychidae)

2005

Acetone extracts of Annona cherimola Mill., Melia azedarach L., Artemisia absinthium L. and Quassia spp., were tested in laboratory trials on young females of Tetranychus urticae Koch (Acariformes,Tetranychidae). In the post-infestation tests, extracts of Melia and Annona caused a high mortality of the target females (84% and 96% for Melia and Annona, respectively) after 24 hours and 100% for both extracts after 48 hours. On the other hand Artemisia extracts caused 84% mortality of females after 10 days even if the oviposition rate was statistically lower than in the controls (2.5 and 6.7 eggs/female/day for Artemisia and controls, respectively).
