Understanding the historical emergence and growth of long-range fisheries can provide fundamental insights into the timing of ecological impacts and the development of coastal communities during the last millennium. Whole-genome sequencing approaches can improve such understanding by determining the origin of archaeological fish specimens that may...

Processed fish is known to have been systematically traded in Europe since the Early Middle Ages to meet increasing demand of incipient markets and religious precepts, yet specific details regarding the supply of different fish in Southern Europe is often missing. Here, we address this gap through an integrated approach involving bone metrics and s...

Abst ract / Zusa m men fassu ng This paper constitutes a fi rst attempt to provide a comprehensive and up-to-date survey of hake (Merluccius merluccius Linnaeus, 1758) fi nds in archaeological sites from the Iberian Peninsula. Even though this deep-water species has been never considered a signifi cant item in terms of fi shing up until 18 th centu...

This article attempts to set out a research agenda on the origin and evolution of hake exploitation in the Northeast Atlantic through a combination of zooarchaeological data with history and fisheries biology. An overview of archaeological hake remains from the Iberian Peninsula is presented and discussed in terms of a series of long-established pa...

Complexity in the processing of the Amyloid Precursor Protein, which generates a mixture of βamyloid peptides, lies beneath the difficulty in understanding the etiology of Alzheimer’s disease. Moreover, whether Aβ peptides have any physiological role in neurons is an unresolved question. By expressing single, defined Aβ peptides in Drosophila, spec...

La ictioarqueología se ocupa del análisis de restos de peces procedentes de yacimientos arqueológicos, con la finalidad de la reconstrucción paleoecológica de los medios acuáticos antiguos y de la paleoeconomía de las poblaciones humanas del pasado. Entre los restos de peces se incluyen huesos, otolitos, dientes y escamas, siendo su análisis una ap...

Background and objective: Understanding neural circuit function is the basis to unravel how memories are created, how the brain integrates sensory inputs or how a complex behaviour is developed. However, this is a difficult task due to the requirement to reconstruct comprehensively functional connections between neurons. It is a good starting point...

Alzehimer´s Disease is a neurodegenerative disorder characterized by early synaptic and late neuronal loss. It is generally accepted that the amyloid Aβ peptide is the primary cause of the disease, although the specific mechanisms that underlie its synaptotoxic and neurotoxic effects are not well understood. To better understand the role of the dif...

Abstract In standard histological technique, aromatic solvents such as xylene and toluene are used as clearing agents between ethanol dehydration and paraffin embedding. In addition, these solvents are used for de-waxing paraffin sections. Unfortunately, these solvents are harmful and therefore adequate substitutes would be useful. We suggest the u...

Massive cell death in cell cultures due to their exposure to the Bulk Photovoltaic Effect (BPE) has been demonstrated using iron-doped lithium niobate (LiNbO 3 :Fe) crystals or micro-particles under low-intensity visible light.

Massive cell death has been provoked in cell cultures due to their exposure to the Bulk Photovoltaic Effect (BPE) of iron-doped lithium niobate (LiNbO 3 :Fe) under low-intensity visible light. The BPE appears in certain crystalline materials that show an asymmetric crystal cell unit arrangement. This feature gives rise to a preferential electronic...

Previous studies have revealed leucokinin (LK) expression in the brain and ventral ganglion of Drosophila CNS. One pair of protocerebrum neurons located in the lateral horn area (LHLK) surrounds the peduncles of the mushroom bodies while two pairs of subesophageal neurons (SELKs) project extended processes to the tritocerebrum and through a cervica...

This work reports a pioneer application of the bulk photovoltaic effect in the biomedical field. Massive necrotic cell death was induced in human tumour cell cultures grown on a bulk photovoltaic material (iron-doped lithium niobate, LiNbO(3):Fe) after irradiation with visible light. Lethal doses (≈100% cell death) were obtained with low-intensity...

The distribution of leucokinin (LK) neurons in the central nervous system (CNS) of Drosophila melanogaster was described by immunolabelling many years ago. However, no detailed underlying information of the input or output connections of their neurites was then available. Here, we provide a more accurate morphological description by employing a nov...

The vertebrate Apolipoprotein D (ApoD) is a lipocalin secreted from subsets of neurons and glia during neural development and aging . A strong correlation exists between ApoD overexpression and numerous nervous system pathologies as well as obesity, diabetes, and many forms of cancer . However, the exact relationship between the function of ApoD an...
