    The use of essential oils and organic acids is generally accepted as an alternative tool for the control of the Varroa Destructor levels in bee's colonies, avoiding mite resistance and reducing the residues contaminations resulting from the systematic application of synthetic chemicals

    Application of GIS in potential beekeeping assessment: Case study of Montesinho Natural Park (Portugal)

    Planners require solutions that address routine work needs and seems essential to improving efficiency and productivity. There are a great number of different factors related to beekeeper activity as well the quality and productivity of different bee products. The spatial analysis is a powerful tool for overlap and relates various levels of information on a map, and consequently a very useful for beekeeping activity planning. This work proposes and applies a methodology to potential beekeeping assessment in Montesinho Natural Park, a region in the northwest of Portugal. The beekeeping potential maps were developed with the following data sources: legal standards, vegetation, land use, topography, water resources, roads, electromagnetic fields, and some honey physico-chemical analysis. The design and implementation of spatial analysis model based on Geographic Information System (GIS) to beekeeping planning activities has already been described by Anjos et al (2014). Spatial analysis techniques allows to define the potential beekeeper map supporting the beekeeper management in this region. Anjos O, Silva G, Roque N, Fernandez P, 2014.

    Organic beekeeping in Portugal

    Get PDF
    Beekeeping in Portugal is an agricultural activity that over the past years has seen a reduction in the number of registered operators. However, this behaviour is not the result of abandonment, as found in general for other agricu lture activities, but is due to an increase of beekeepers professionalism, as evidenced by the steady number of registered hives. The decrease in the number of beekeepers refiects the actual disappearance of hobbyists and those farmers who practiced beekeeping as a complementary rural activity (low number of hives / beekeeper) and the appearance of new operators, wi th higher numbers of hives, where the economic result of beekeeping reflects its core profit

    Este estudo tem como objectivos conhecer o perfil do consumidor do mel e descrever os seus hábitos de consumo e compra. Foi elaborado um estudo quantitativo que teve como base a construção de um questionário, que foi aplicado a 172 indivíduos do Distrito de Bragança. Através da análise descritiva dos dados faz-se a caracterização da amostra e descrevem-se os hábitos de consumo e compra do mel. Participaram neste estudo 172 indivíduos, dos quais 41,9% são do sexo masculino e 58,1% são do sexo feminino. Verificou-se que a esmagadora maioria é consumidor de mel (94,8%), prefere o mel da região porque está mais disponível, é mais saboroso e tem qualidade (70,9%). A principal forma de utilização do mel é combinado com outros alimentos (60,5%), o local preferido para a sua compra é junto do produtor (51,7%) e o factor que mais pesa na decisão de compra é o paladar (52,3%). To determine the honey consumer’s profile and to describe your purchase and consume habits are the objectives of this study. A cross-sectional survey was carried out in a probabilistic sample including 172 individuals of the Braganza region population. After, data descriptive analyses is done characterization of the sample and are described purchase and consume habits of the inquiry. In this study participated 172 individuals, of which 41,9% are male and 58,1% are female. It was verified that the smashing majority is honey consumer (94,8%), they prefer the national honey because it is more available, it is tastier, it is quality and it is trustworthy (70,9%). The main form honey use is mixed with other foods (60,5%), the favorite place for the honey purchase is near the producer (51,7%) and the factor that more it weighs in the purchase decision this product is the palate (52,3%)

    The Parkinson's Disease-Linked Protein DJ-1 Associates with Cytoplasmic mRNP Granules During Stress and Neurodegeneration.

    Mutations in the gene encoding DJ-1 are associated with autosomal recessive forms of Parkinson's disease (PD). DJ-1 plays a role in protection from oxidative stress, but how it functions as an "upstream" oxidative stress sensor and whether this relates to PD is still unclear. Intriguingly, DJ-1 may act as an RNA binding protein associating with specific mRNA transcripts in the human brain. Moreover, we previously reported that the yeast DJ-1 homolog Hsp31 localizes to stress granules (SGs) after glucose starvation, suggesting a role for DJ-1 in RNA dynamics. Here, we report that DJ-1 interacts with several SG components in mammalian cells and localizes to SGs, as well as P-bodies, upon induction of either osmotic or oxidative stress. By purifying the mRNA associated with DJ-1 in mammalian cells, we detected several transcripts and found that subpopulations of these localize to SGs after stress, suggesting that DJ-1 may target specific mRNAs to mRNP granules. Notably, we find that DJ-1 associates with SGs arising from N-methyl-D-aspartate (NMDA) excitotoxicity in primary neurons and parkinsonism-inducing toxins in dopaminergic cell cultures. Thus, our results indicate that DJ-1 is associated with cytoplasmic RNA granules arising during stress and neurodegeneration, providing a possible link between DJ-1 and RNA dynamics which may be relevant for PD pathogenesis

    O efeito do timol como acaricida alternativo na qualidade do mel em modo de preparação biológica

    No full text
    Para a apicultura em modo de produção biológica, MPB, o uso de acaricidas é legalmente restringido aos óleos essenciais e a alguns ácidos orgânicos que se podem encontrar entre os vários constituintes do mel, pois não é permitido adicionar qualquer composto sintético à sua composição. As principais alternativas no controlo da varroa são o timol, o ácido oxálico e o ácido fórmico, substâncias regularmente usadas em todo o mundo com bons resultados
