Primera cita de cabirol, Capreolus capreolus (Linnaeus, 1758) (Artyodactila, Cervidae) per a la provincia d’Alacant

Se da a conocer el primer registro de recolonización del corzo, Capreolus capreolus (Linnaeus, 1758), en la provincia Alicante. La especie se ha localizado mediante fototrampeo en una de las comarcas montañosas situadas en el norte y el interior de dicho territorio. Se plantean igualmente las diferentes hipótesis de recolonización de la especie en la zona, siendo la más plausible la reintroducción natural por expansión de las poblaciones provenientes de provincias colindantes.The first record of the roe deer, Capreolus capreolus (Linnaeus, 1758), from the Alicante province is reported. This species was identified by phototrapping in one of the mountainous regions in the north of this area. The various hypotheses of recolonization of the species in the area are considered, the most plausible being natural reintroduction due to expansion of the populations from neighbouring provinces.Es dona a conèixer el primer registre de recolonització del cabirol, Capreolus capreolus (Linnaeus, 1758), a la província d’Alacant. L’espècie s’ha localitzat mitjançant parament fotogràfic en una de les comarques muntanyoses situades al nord i a l’interior del territori esmentat. Es plantegen així mateix les diferents hipòtesis de recolonització de l’espècie a la zona, la més plausible de les quals és la reintroducció natural per expansió de les poblacions provinents de les províncies limítrofes

Human Biomonitoring of food contaminants in Spanish children: Design, sampling and lessons learned

[EN] Human Biomonitoring (HBM) studies are highly useful for evaluating population exposure to environmental contaminants and are being carried out in increasing numbers all over the world. The use of HBM in the field of food safety, in a risk assessment context, presents a growing interest as more health-based guidance values (HBGV) in biological matrices are derived, and can be used in a complementary way to the external exposure approaches such as total diet studies or surveillance programmes. The aims of the present work are: i) to describe the methodological framework of the BIOVAL study, a cross-sectional HBM program carried out by the Health Department of the Regional Government of Valencia (Spain), that is linked to the food safety official control, and is focused on children from 6 to 11 years of age ii) to explain and discuss the pre-analytical results iii) to report and discuss on lessons learned from its design and implementation. The study population included 666 children from whom urine and hair were taken in order to analyse different biomarkers of exposure to food pollutants.Pérez-Torres, R.; Doménech Antich, EM.; Coscollà, C.; Yusà, V.

Peroxisomal fission is modulated by the mitochondrial Rho-GTPases, Miro1 and Miro2

Peroxisomes are essential for a number of cellular functions, including reactive oxygen species metabolism, fatty acid β-oxidation and lipid synthesis. To ensure optimal functionality, peroxisomal size, shape and number must be dynamically maintained; however, many aspects of how this is regulated remain poorly characterised. Here, we show that the localisation of Miro1 and Miro2-outer mitochondrial membrane proteins essential for mitochondrial trafficking-to peroxisomes is not required for basal peroxisomal distribution and long-range trafficking, but rather for the maintenance of peroxisomal size and morphology through peroxisomal fission. Mechanistically, this is achieved by Miro negatively regulating Drp1-dependent fission, a function that is shared with the mitochondria. We further find that the peroxisomal localisation of Miro is regulated by its first GTPase domain and is mediated by an interaction through its transmembrane domain with the peroxisomal-membrane protein chaperone, Pex19. Our work highlights a shared regulatory role of Miro in maintaining the morphology of both peroxisomes and mitochondria, supporting a crosstalk between peroxisomal and mitochondrial biology

Another beauty of analytical chemistry: chemical analysis of inorganic pigments of art and archaeological objects

[EN] This lecture text shows what fascinating tasks analytical chemists face in Art Conservation and Archaeology, and it is hoped that students reading it will realize that passions for science, arts or history are by no means mutually exclusive. This study describes the main analytical techniques used since the eighteenth century, and in particular, the instrumental techniques developed throughout the last century for analyzing pigments and inorganic materials, in general, which are found in cultural artefacts, such as artworks and archaeological remains. The lecture starts with a historical review on the use of analytical methods for the analysis of pigments from archaeological and art objects. Three different periods can be distinguished in the history of the application of the Analytical Chemistry in Archaeometrical and Art Conservation studies: (a) the "Formation'' period (eighteenth century1930), (b) the "Maturing'' period (1930-1970), and (c) the "Expansion'' period (1970-nowadays). A classification of analytical methods specifically established in the fields of Archaeometry and Conservation Science is also provided. After this, some sections are devoted to the description of a number of analytical techniques, which are most commonly used in routine analysis of pigments from cultural heritage. Each instrumental section gives the fundamentals of the instrumental technique, together with relevant analytical data and examples of applications.Financial support is gratefully acknowledged from Spanish ‘‘I+D+I MINECO’’ projects CTQ2011-28079-CO3-01 and CTQ2014-53736-C3-1-P supported by ERDEF funds.Domenech Carbo, MT.; Osete Cortina, L.

Influence of diet in urinary levels of metals in a biomonitoring study of a child population of the Valencian region (Spain)

[EN] Pollution by trace elements and its possible effect on organisms has become a worldwide concern due to the increasing presence of trace elements in the environment and especially in the food chain. Exposure to chemicals has traditionally been measured using environmental samples, however, human biomonitoring brings a different perspective, in which all sources and exposure pathways are integrated. The objective of this paper is to discern the possible relationship between children's diet and the metals found in children urine. With this aim in mind, a total of 120 voluntaries participated in a diet survey carried out in a school-aged population (age 6-11) from the Valencian region. In addition, twenty trace elements were analysed in children urine (arsenic, antimony, barium, beryllium, caesium, cadmium, cobalt, copper, lead, manganese, mercury, molybdenum, nickel, platinum, selenium, thallium, thorium, uranium, vanadium and zinc). Results permitted to compare metal levels in urine with metal levels of other biomonitoring studies to conclude that values, including ours, were similar in most studies. On the other hand, children who ate more vegetables had the highest values in cadmium, copper, molybdenum, antimony, thallium, vanadium, and zinc, while those who ate more fish reached higher values in mercury. Finally, children who ate more cereals and baked products had higher values in total arsenic. (c) 2017 Elsevier B.V.

Experimental and theoretical study of line mixing in methane spectra. IV. Influence of the temperature and of the band

The infrared bands line-mixing effects of methane perturbed by nitrogen were discussed at different pressures. The spectral shapes of the ν2, ν4 and ν3 bands were compared at room temperature while the ν3 region was employed for the investigation of thermal effects. The effects of collisions in the ν4 region's spectra were calculated at the room temperature. The Coriolis coupling between ν2 and ν4 vibrational states resulted in the failure of evolution modeling with increasing pressure of absorption.© 2000 American Institute of PhysicsPeer Reviewe
