Del medio natural a los paisajes pastorales : ocupación de las zonas de alta montaña en los Pirineos centrales de Cataluña desde el Mesolítico a la Edad del Bronce (c. 9000-1000 cal ANE)

En este artículo presentamos los resultados de los trabajos de investigación arqueológica y paleoambiental llevados a cabo entre 2000 y 2014 en el Parque Nacional de Aigüestortes i Estany de Sant Maurici (PNAESM) y en su área periférica. Dichos trabajos comprenden la prospección sistemática de la mayor parte del territorio, entre 1500 y 3000 m de altitud, que ha permitido documentar 350 sitios arqueológicos, proporcionando 78 dataciones radiocarbónicas que comprenden una secuencia de ocupación de la zona de 10700 años. Asimismo, se ha completado la excavación de tres yacimientos arqueológicos: Cova del Sardo de Boí, Abric de l'Estany de la Coveta I y el Dolmen de la Font dels Coms. El análisis arqueológico y paleoambiental de los sitios, de diversos perfiles y de 5 registros lacustres permiten modelizar la historia de las actividades económicas humanas en la alta montaña y el proceso de construcción de los primeros paisajes pastorales.Artikulu honetan, Aigüestortes i Estany de Sant Maurici (PNAESM) parke nazionalean eta parkearen eremu periferikoan 2000. urtetik 2014ra eginiko ikerketa arkeologiko eta paleoanbientalen emaitzak aurkeztuko ditugu. Eginiko lanen artean daude lurraldearen zatirik handienaren prospekzio sistematikoa, 1.500-3000 m-ko altitudean egina, eta horri esker, 350 gune arkeologiko dokumentatu eta 78 datazio erradiokarboniko eskuratu ditugu, gunean 10700 urtean izandako okupazioaren sekuentziari lotutakoak. Era berean, hiru aztarnategi arkeologikoren indusketa ere burutu dugu: Cova del Sardo de Boí, Abric de l'Estany de la Coveta I eta Dolmen de la Font dels Coms. Guneen, profilen eta 5 aintzari-erregistroren inguruan egindako azterketa arkeologiko eta paleoanbientalak aukera ematen dute goi mendietako giza jarduera ekonomikoen historia eta lehen artzantza-paisaien eraikitze-prozesua modelizatzeko.This paper presents the results of the archaeological and palaeoecological research conducted between 2000 and 2014 in the Aigüestortes i Estany de Sant Maurici National Park (PNAESM). This included the systematic survey of the most of the National Park territory, included at altitudes between 1500 and 3000 m a.s.l. During the surveys, 350 archaeological sites have been detected and 78 radiocarbon dates have been realized, providing a sequence of human occupation from 10700 cal BP to modern times. In addition, three archaeological sites with stratified deposits have been fully excavated: Cova del Sardo de Boí, Abric de l'Estany de la Coveta I and Dolmen de la Font dels Coms. In parallel, 5 sedimentary cores have been extracted from lakes and one pigbog, from the Natural Park of Alt Pirineu (PNAP) and National Park (PNAESM) areas, providing a full palaeoecological sequence from the last 17.000 years cal BP. This archaeological and palaeoecological dataset (e.g. soil-sites and lake records) allowed advancing new models about the anthropization of the high-altitude areas and the social construction of pastoral landscapes

P019. Transcutaneous supraorbital neurostimulation in “de novo” patients with migraine without aura: the first Italian experience

Transcutaneous supraorbital neurostimulation (tSNS) has been recently found superior to sham stimulation for episodic migraine prevention in a randomized trial. We evaluated both the safety and efficacy of a brief period of tSNS in a group of patients with migraine without aura (MwoA)

Tumor size, node status, grading, HER2 and estrogen receptor status still retain a strong value in patients with operable breast cancer diagnosed in recent years.

Breast cancer prognosis has improved greatly in recent years. Consequently, a thorough search for sensitive prognostic factors, able to help clinicians offer appropriate therapy, has become a priority in this area. In this study, we considered all new cases of invasive breast cancer diagnosed in the Province of Modena, Italy, between 1997 and 2007, registered by the Modena Cancer Registry. The principal endpoint of this study was relapse-free survival (RFS). A set of 11 clinic and pathological parameters was investigated. After a median follow-up of 73 months, 494 relapses were recorded. Tumor size, node status, grading, HER2 and estrogen receptor status were retained as independent factors in a multivariate analysis. Using these variables, a prognostic model was devised to identify three groups at different risk. In the training sample, the 5-year RFS rates resulted 96.0%, 82.9% and 63.7% in patients at low, intermediate and high risk, respectively (p < 0.0001). In the validation sample, the 5-year RFS was 96.2%, 85.4% and 66.9%, respectively. To conclude our study demonstrates that a very simple prognostic index based on easily available clinical data may represent a useful tool for the identification of patients at different risk of relapse and may be a notable device to predict who truly benefits from medical treatment

Portraits of Dayton, Alabama: Images of Women and Place in the Antebellum South

The scholarship on women in the antebellum American South is extensive. Since the 1980s, historians have debated the relationships between white plantation mistresses and the Black women they enslaved. This project adds to that conversation by examining the extant material culture from Dayton, Alabama, to understand the lives of slave-holding mother and daughter, Thyrza Jane Catlin Cade (1811-1876) and Adolpha Thompson Cade Reeves (1845-1888) and the families they enslaved. This project combines gender studies with art historical analysis to ask questions about whether stories of white, elite slaveholding planter families from the Deep South anything have left to teach us. Through the use of primary source historical research such as newspaper articles, census records, and family probate records as well as material culture analysis, this project examines antebellum Dayton through a study of its extant material culture to helps expose the ways that gender, race, and power intersect with an understanding of southern place. This project illuminates the ways that the study of objects can help tell the stories of women, both enslaved and free, in the antebellum South. I analyze a pair of portraits of Thyrza Jane and Adolpha and conclude that material culture can help us understand the ways that white women played a notable role in reinforcing the patriarchal structures that upheld slavery because it was ultimately to the benefit of elite, white slaveholding women to actively participate in this system

The Rieske Iron-Sulfur Protein: Import and Assembly into the Cytochrome bc1 Complex of Yeast Mitochondria

The Rieske iron-sulfur protein, one of the catalytic subunits of the cytochrome bc1 complex, is involved in electron transfer at the level of the inner membrane of yeast mitochondria. The Rieske iron-sulfur protein is encoded by nuclear DNA and, after being synthesized in the cytosol, is imported into mitochondria with the help of a cleavable N-terminal presequence. The imported protein, besides incorporating the 2Fe-2S cluster, also interacts with other catalytic and non-catalytic subunits of the cytochrome bc1 complex, thereby assembling into the mature and functional respiratory complex. In this paper, we summarize the most recent findings on the import and assembly of the Rieske iron-sulfur protein into Saccharomyces cerevisiae mitochondria, also discussing a possible role of this protein both in the dimerization of the cytochrome bc1 complex and in the interaction of this homodimer with other complexes of the mitochondrial respiratory chain

Análisis etnoarqueológico del valor social del producto en sociedades cazadoras-recolectoras

This work was formulated as a consequence of considering the necessity of a value theory (that is, an economical theory), in archaeology. From our materialist perspective, that would allow us to set the basis for an objective analysis of past societies, understanding that only through the knowledge of their material life conditions and their social organization we would be able to know their historical becoming. We were reaching a common index that would make possible to compare different occupations and sites in Tierra del Fuego. This index would be used to make inferences about the amount of work invested in every occupation, amount of work that could be understood as the duration of the occupation or as the amount of people in that camp-site. On the other hand, on the basis of the Main Contradiciton formulation, we could establi sh a mechanism to quantify different participation in the production cycle and the existing differences in the access to the consumption of what has been produced. This will drive us to the formulation of a method to identify social explotation.Este trabajo surgió como consecuencia de varias preocupaciones. En primer lugar, considerábamos, desde hacía ya tiempo, la necesidad de una teoría del valor (económica, por tanto), en Arqueología; preocupación compartida con otros investigadores/as. Desde nuestra perspectiva materialista, ello nos había de permitir sentar las bases para un análisis objetivo de las sociedades prehistóricas, entendiendo que tan sólo a través delconocimiento de Las condiciones materiales de vida, y de la estructuración u organización de las relaciones sociales, podremos llegar a conocer el devenir histórico de las mismas. Buscábamos un índice, un común denominador, que nos permitiera poder comparar diferentes ocupaciones y yacimientos actualmente (y desde hace ya más de una década) en estudio en Tierra del Fuego (Argentina). Este índice debería permitirnos, por un lado realizar inferencias sobre la cantidad de trabajo invertida en cada ocupación de los diferentes asentamientos Yámana. Lo cual podría ser interpretado en clave de ti empo de ocupación o de cantidad de personas ocupando el sitio. Y por otro lado, y sobre la base de la formulación de la Contradicción Principal, podría establecer un mecanismo que nos permitiera cuantificar la participación diferencial en la producción y las disimetrías en el acceso al consumo de lo producido, estableciendo un «cálculo» para la identificación de la explotación. Este último interés tiene mucho que ver con el aceptado concepto de «sociedades igualitarias » aplicado a las sociedades cazadoras recolectoras, concepto cuestionable en tanto que surge de una aproximación androcéntrica. Este trabajo ha sido posible, en el caso de la sociedad Yámana, gracias a la exhaustiva y variada información etnográfica confrontada a una completa información arqueológica. El objetivo final es conseguir generar propuesta metodológica contrastada que nos permita este tipo de acercamientos a sociedades cazadoras-recolectoras prehistóricas

Rapporto tecnico sulle attività di campionamento della “Campagna Oceanografica CISAS_2” Crotone 07-12 dicembre 2017

Le attività di campionamento ed acquisizione dati svolte durante la campagna CISAS_2 si inseriscono in seno al progetto “Centro internazionale di studi avanzati su ambiente ed impatti su ecosistema e salute umana (CISAS)” del CNR. L’obiettivo principale del progetto CISAS è la comprensione dei processi e dei meccanismi di trasferimento di alcuni contaminanti convenzionali (metalli pesanti, POPs, radionuclidi, ecc.) e di alcuni contaminanti emergenti (PDBE, composti farmaceutici di nuova generazione, ecc.) dall’ambiente inteso come l’insieme di atmosfera-suoli-acque sotterranee-matrici marine (acque e sedimento) all’ecosistema e all’uomo. Le aree di indagine del progetto sono i Siti di Interesse Nazionale (SIN) di Priolo, Milazzo-Pace del Mela e Crotone che, per specificità e modalità di impatto antropogenico sull’ambiente, l’ecosistema e la salute umana, coprono un ampio spettro di tipologie di interesse. La campagna oceanografica CISAS_ 2 è stata dedicata alla caratterizzazione ambientale del SIN di Crotone, nonché all’identificazione delle sorgenti dei contaminanti la cui distribuzione si ritiene di interesse (per i valori di concentrazione riscontrati nelle diverse matrici ambientali e per livello di tossicità associata agli effetti degli stessi sulla salute dell’ecosistema e dell’uomo) e i pathways di deposizione nelle aree di interesse

Actual and Illusory Perception in Parkinson's Disease and Dystonia: A Narrative Review

Sensory information is continuously processed so as to allow behavior to be adjusted according to environmental changes. Before sensory information reaches the cortex, a number of subcortical neural structures select the relevant information to send to be consciously processed. In recent decades, several studies have shown that the pathophysiological mechanisms underlying movement disorders such as Parkinson's disease (PD) and dystonia involve sensory processing abnormalities related to proprioceptive and tactile information. These abnormalities emerge from psychophysical testing, mainly temporal discrimination, as well as from experimental paradigms based on bodily illusions. Although the link between proprioception and movement may be unequivocal, how temporal tactile information abnormalities and bodily illusions relate to motor disturbances in PD and dystonia is still a matter of debate. This review considers the role of altered sensory processing in the pathophysiology of movement disorders, focusing on how sensory alteration patterns differ between PD and dystonia. We also discuss the evidence available and the potential for developing new therapeutic strategies based on the manipulation of multi-sensory information and bodily illusions in patients with these movement disorders
