The European Commission recognises the essential role of soil biology in soil functioning and delivery of ecosystem services, but information is currently lacking evaluate of how these vary across soil and land-use types at a European scale. This study evaluated the measurement of the initial rate of soil basal respiration (BR) as a potential biological indicator of ecosystem service provision. The purpose of t...
Purpose The main objective of the present study was to evaluate the toxicity of two reference chemicals, Carbendazim and Phenmedipham, for the compostworm Eisenia andrei (effects of Carbendazim) and the potworm Enchytraeus crypticus (effects of Phenmedipham) in 12 Mediterranean soils with contrasting soil properties. The observed toxicity was also compared to that obtained for OECD standard soil, used as a cont...
The potential terrestrial toxicity of three pesticides, azoxystrobin, chlorothalonil, and ethoprophos was evaluated using reproduction ecotoxicological tests with different non-target species: the collembolan Folsomia candida, the earthworm Eisenia andrei, and the enchytraeid Enchytraeus crypticus. All reproduction tests were performed with natural soil from a Mediterranean agricultural area (with no pesticide ...
The present study aimed to assess the environmental fate of the insecticide and nematicide ethoprophos in the soil–water interface following the pesticide application in simulated maize and potato crops under Mediterranean agricultural conditions, particularly of irrigation. Focus was given to the soil–water transfer pathways (leaching and runoff), to the pesticide transport in soil between pesticide applicatio...
Before the latest UICC-AJCC’s revision of the TNM classification, the esophagogastric junction carcinoma could, for staging purposes, be classified as esophageal or gastric. This fact itself generated a number of inconsistencies when addressing these cancers. The aim of this Project is try to clarify the framework of the esophagogastric junction carcinoma, regarding staging, intending the authors to answer the ...
This work took place in the Tabuaço prospect, which corresponds to an area of 45 km2 where exploration for W-skarn deposits is being carried out by Colt Resources. The study now presented results from collaboration among that company, the University of Aveiro, the Geobiotec research unit and the team of the Petrochron project (PTDC/CTE-GIX/112561/2009) and it was focussed on the lithologies recognized, both in...
As litologias identificadas na área da Quinta de São Pedro das Águias correspondem a: xistos biotíticos, xistos negros, mármores, rochas calcossilicatadas s.s. e skarns da sequência metassedimentar da Formação de Bateiras, pertencente ao Grupo do Douro do CXG; granito de Paredes da Beira-Tabuaço; vários corpos aplíticos e pegmatíticos. Para as litologias granitoides, foi obtida uma isócrona Rb-Sr de 311±7 Ma (M...
O Síndrome de Dumping é uma das complicações conhecidas da cirurgia gástrica no adulto, sendo considerada pouco frequente na criança. Os casos descritos na infância associam-se quase exclusivamente à Fundoplicatura de Nissen, principalmente se associada a piloroplastia.O quadro clínico na criança raramente é sobreponível ao quadro clássico de Síndrome de Dumping do adulto, manifestando-se por sintomas transitór...
Introdução: As anomalias do tracto urinário são detectadas com uma frequência cada vez maior devido à sistematização da vigilância ecográfica durante a gravidez aliada à sofisticação técnica e à experiência dos ecografistas.Objectivo: Analisar os principais diagnósticos pós-natais investigados na sequência do estudo evolutivo prolongado das uropatias fetais seguidas no ambulatório da nefrologia pediátrica do Ho...
Os probióticos constituem um motivo de investigação extremamente actual e que interessa a várias áreas profissionais, nomeadamente, à medicina, à veterinária e à indústria alimentar. Na parte que à medicina diz respeito, os probióticos têm despertado o interesse de microbiologistas, de imunologistas, de nutricionistas, de internistas, de pediatras e de vários outros especialistas (gastroenterologistas, cardiolo...
