Algunas precisiones sobre la terminología empleada en la segunda parte del Tardiglaciar en Europa Central y el problema de su aplicación en el SW de Europa

2026-04-28T00:01:59Z

[ES] Los interestadiales Meiendorf, Bølling y Allerød han sido definidos en la parte norte de Centroeuropa y se han aplicado como cronozonas en diferentes contextos paleoclimáticos en el Hemisferio Norte durante el Tardiglaciar. La comunidad científica que se dedica a las investigaciones de tipo paleoclimático y arqueológico parecen obviar el hecho de que el interestadial Meiendorf ha sido definido como predecesor de la secuencia Bølling-Allerød y que hay enormes dificultades con la sincronización de la secuencia Dryas Antiguo-Bølling-Dryas Medio. En Centroeuropa, la sincronización de registros polínicos muy detallados con el sondeo en los hielos GRIP demuestra la existencia de un gradiente climático muy fuerte desde el sur al norte de Europa durante el Tardiglaciar. Por lo tanto, los interestadiales del norte de Europa (Meiendorf, Bølling, Allerød) no pueden servir como cronozonas del Tardiglaciar de forma universal con referencia a sus composiciones polínicas características, pero son de gran importancia para la comprensión de la historia de la vegetación a nivel regional. Los sondeos realizados en el Ártico nos ofrecen una información climática de todo el Tardiglaciar y funcionan como secuencias de tipo cronoestratigráfico. La sincronización detallada de las secuencias terrestres con los sondeos llevados a cabo en el Ártico podrá realizarse en un futuro próximo, usando la calibración radiocarbónica de alta precisión basada en la dendrocronología tardiglaciar.

L´axe Rhin-Rhône au Paléolithique supérieur récent: l´exemple des molusques utilisés comme objets de parure

2026-04-28T00:01:58Z

[EN] The Rhine-Rhone Axis in the Late Upper Palaeolithic: the Exemple of Molluscs used as Ornament Objects. Many of these are to be found in the Late Glacial archaeological sites which are located on the Rhine-Rhone axis. In this paper we mainly analyse the ones made of mollusc shells which are nowadays found on the Mediterranean or Atlantic coasts. Their presence on territories which are very far from the sea ( hundreds of kilometers) make think of contact nets between the human groups of this period through a natural corridor which allowed the communication between Atlantic and Mediterranean Europe.

Las perlas de madera fósil del Terciario y los objetos de adorno-colgantes sobre dientes de zorro y ciervo del Magdaleniense de Gönnersdorf y Andernach-Martinsberg-2, (Neuwied, Rheinland Pfalz, Alemania)

2026-04-28T00:01:53Z

[ES] En los yacimientos magdalenienses al aire libre de Gonnersdorf y Andernach-Martinsberg-2 existen gran cantidad de objetos de adorno-colgantes, realizados a partir de diferentes materias primas. De ellos, los que aquí se estudian son, por una parte, las perlas de madera fósil del Terciario, muy abundantes, proponiéndose una cadena operativa para su realización; otros son los dientes de zorro perforados, destacándose los premolares perforados (P2, P3 y P4, a los que además de la perforación se les practica un aserramiento en la raíz de menor tamaño. A su vez, se estudian los caninos atrofíeos de ciervo perforados. Por último, se localizan estos objetos de adorno, tanto en la superficie, como en las fosas de las Concentraciones individualizadas de cada uno de los yacimientos (haciendo incapié en la fosa 19 de la Concentración I de Gonnersdorf), y se ofrece una visión de la movilidad de las gentes de fines del Magdaleniense en Europa Central a través de los objetos de adorno-colgantes que encontramos en este territorio

El significado cronológico de la Fauna Fría durante el Tardiglaciar en la P. Ibérica

2026-04-23T00:01:23Z

[ES] Durante las últimas décadas se ha venido demostrando la existencia de oscilaciones climáticas ocurridas durante del Tardiglaciar en el Hemisferio Norte por medio de correlaciones entre los diferentes tipos de archivos (sondeos glaciares y marinos y secuencias terrestres). Esto ha permitido detectar un amplio espectro de parámetros que nos ayuda a comprender mejor los cambios climáticos ocurridos en Europa. Mientras los territorios situados en el Norte y Noroeste de Europa se ven privados de la influencia directa de la Corriente del Golfo durante el Tardiglaciar, la P. Ibérica está situada en estos momentos al Este de la parte norte de dicha Corriente Noratlántica. Aquí, los cambios acaecidos parecen haber influido menos en la flora y fauna que en los territorios situados más al Norte. Sin embargo, de forma episódica, estas condiciones del Máximo Glaciar pudieron penetrar dentro de la franja norte de la P. Ibérica viéndose afectadas también las regiones del centro de este territorio. En este artículo se analizan diferentes datos de Fauna Fría (representaciones parietales, mobiliares y restos faunísticos) de determinados yacimientos peninsulares durante el Tardiglaciar, discutiéndose sus fechas absolutas y relacionándolas con las del "El Magdaleniense con Triángulos".

Reassessing Craft in the Late Acheulean: Technological Insights from Jaljulia Handaxes (Levant)

2026-03-26T01:00:59Z

[EN] Recent research on the Lower Paleolithic of the Levant has re-evaluated technical trends defined for the Acheulean technocomplex during the 1970s, trends built upon typological analysis of handaxe assemblages. To this end, new methods are being applied to old and new collections in order to assess handaxe morphological and technological variation over time, opening a discussion about the technical skills of Acheulean knappers, also referred to as “craftmanship” (hereafter referred to as “craft”). In this context, morphometric studies conducted at the Late Acheulean site of Jaljulia have highlighted the crudeness and high morphological variability of the bifacial assemblage, challenging the 1970s idea of handaxe increasing refinement over time. Interestingly, the authors do not attribute this variability to a lack of knapping skill—as irregular and non-standardized productions are traditionally interpreted—but to an expedient chaîne opératoire of tool production. Produced predominantly in brecciated flint, collected and modified on the spot, the sample studied is interpreted by the authors as tools mostly adapted for bone-crushing purposes. This paper aims to offer a new perspective on this assemblage by conducting a critical technological analysis of the handaxes from the oldest locality on-site, Area D, taking into account raw material constraints as well as the site’s function as a handaxe production workshop, among other activities conducted at this Paleolithic landscape. Our results suggest the presence of pieces discarded during the production process, which contributes to the increased morphological variability observed in the assemblage. Our analysis discusses the expedient character of Jaljulia’s handaxe reduction sequence and points to the production of three distinct techno-types, potentially associated to a wider variety of tasks. To conclude, we discuss our results in the context of the Late Acheulean of the Levant, within the broader framework of technological trends and associated technical skills in the late Acheulean.

The Effect of Rehabilitation Therapy in Children with Intervened Congenital Heart Disease: A Study Protocol of Randomized Controlled Trial Comparing Hospital and Home-Based Rehabilitation.

2026-03-21T01:00:41Z

[EN Children who suffer from congenital heart defects (CHDs) have a decreased ability to perform physical exercise and consequently have a decrease in their functional capacity. The main causes of this decrease in functional capacity have been related on the one hand to residual hemodynamic defects and, at the same time, to a situation of physical deconditioning due to inactivity, as well as problems in lung function, especially the presence of restrictive patterns that influence the amount of O2 insufflated (decreased maximum VO2), consequently generating a deficient maximum O2 consumption and maximum work rate. This represents an important prognostic value, since it constitutes an independent predictor of death and hospitalization. This study aims to determine the benefits obtained regarding respiratory function, exercise capacity, and quality of life after implementing a hospital-based cardio-respiratory rehabilitation program compared to a home-based Cardio-respiratory Physical Activity Program in patients with intervened CHDs. Methods: This is a randomized controlled trial on the effectiveness of two different rehabilitation programs on respiratory function, exercise capacity, and quality of life in patients with CHDs conducted at the Child Cardiology and Congenital Heart Disease Unit of the University Hospital Complex of A Coruña (CHUAC). There will be two groups: Cardio-respiratory rehabilitation group program conducted in a face-to-face format at the hospital (n = 26) and a study group that follows a home-based Cardio-respiratory Physical Activity Program (TELEA) (n = 26). The measurement variables will be respiratory function, forced vital capacity (FVC), forced expiratory volume in the first second (FEV1), maximum expiratory flow (PEF), the Tiffeneau index (FEV1 /FVC), forced expiratory flow (FEF25%, FEF50%, FEF75%, FEF25-75%), exercise capacity (peak VO2), and the quality of life of these children and their families. Conclusions: The implementation of cardiac and pulmonary rehabilitation programs in children with CHDs is essential to improve their quality of life, exercise tolerance, and socialization. These programs optimize life expectancy and promote integration, being crucial for their physical and emotional well-being.

Restless Legs Syndrome in Patients with Psoriatic Arthritis: Association with Inflammatory and Clinical Parameters and Other Comorbidities-A Cross-Sectional Observational Study.

2026-03-21T01:00:35Z

[EN]Introduction/Objectives: Restless legs syndrome (RLS), a chronic neurological disorder related to brain iron metabolism, has been linked to immune-mediated inflammatory conditions such as psoriatic arthritis (PsA). However, the role that inflammation plays in this association and the impact of RLS on PsA outcomes remain unclear. This study aims to investigate the association between RLS and inflammatory/clinical parameters in PsA patients. Materials and Methods: In this cross-sectional study, 230 PsA patients completed the International Restless Legs Syndrome Study Group (IRLSSG) screening questionnaire, with diagnoses confirmed by a neurologist. Data collected included clinical features, disease activity, and comorbidities (obesity, anxiety, depression, insomnia, and fibromyalgia). Results: In total, forty-six patients met the IRLSSG criteria (20%). Those with RLS more frequently had polyarthritis (27% vs. 6%; p < 0.001), more swollen joints (2.0 vs. 1.4; p = 0.04), greater psoriatic involvement (5.7 vs. 3.6; p < 0.001), greater fatigue (39.0 vs. 30.5; p < 0.001), and greater disease activity (14.5 vs. 10.5; p < 0.001). They also exhibited increased disease impact (4.7 vs. 2.9; p < 0.001), poorer functioning (0.7 vs. 0.5; p = 0.01), and higher levels of anxiety (8.0 vs. 5.5; p < 0.001), depression (6.5 vs. 3.9; p < 0.001), and sleep disturbance (13.9 vs. 8.7; p < 0.001). Skin lesions and polyarthritis explained nearly 40% of RLS cases (Odds Ratio (OR) 1.4; 95% Confidence Interval (CI) 1.03-2.0; p = 0.03 and OR 1.03; 95% CI 1.00-1.9; p = 0.04). Conclusions: Psoriatic activity and inflammation may contribute to RLS in PsA. The coexistence of RLS was associated with greater disease activity, greater disease impact, and more emotional and sleep-related comorbidities.

Effect of Physical Exercise on Telomere Length: Umbrella Review and Meta-Analysis.

2026-03-21T01:00:37Z

[EN]Telomere length (TL) is a marker of cellular health and aging. Physical exercise has been associated with longer telomeres and, therefore, healthier aging. However, results supporting such effects vary across studies. Our aim was to synthesize existing evidence on the effect of different modalities and durations of physical exercise on TL. The aim of this study was to explore the needs and expectations of individuals with physical disabilities and their interventionists for the use of a virtual reality physical activity platform in a community organization. We performed an umbrella review and meta-analysis. Data sources included PubMed, Embase, Web of Science, Cochrane Library, and Scopus. We selected systematic reviews and meta-analyses of randomized and nonrandomized controlled clinical trials evaluating the effect of physical exercise on TL. Our literature search retrieved 12 eligible systematic reviews, 5 of which included meta-analyses. We identified 22 distinct primary studies to estimate the overall effect size of physical exercise on TL. The overall effect size was 0.28 (95% CI 0.118-0.439), with a heterogeneity test value Q of 43.08 (P=.003) and I² coefficient of 51%. The number of weeks of intervention explained part of this heterogeneity (Q_B=8.25; P=.004), with higher effect sizes found in studies with an intervention of less than 30 weeks. Exercise modality explained additional heterogeneity within this subgroup (Q_B=10.28, P=.02). The effect sizes were small for aerobic exercise and endurance training, and moderate for high-intensity interval training. Our umbrella review and meta-analysis detected a small-moderate positive effect of physical exercise on TL, which seems to be influenced by the duration and type of physical exercise. High quality studies looking into the impact of standardized, evidence-based physical exercise programs on TL are still warranted.

Impact of physical exercise on memory and learning in healthy older women: a quasi-experimental study.

2026-03-21T01:00:36Z

[EN]The population of people over the age of 65 is currently growing thanks to social and health policies. It presents an increase in age-related diseases due to a series of morphological and physiological changes in these population groups. We aimed to study the effect of a physical exercise program on memory and learning. A quasi-experimental pilot study carried out with a sample of 73 healthy female subjects who were divided into two groups: an intervention group and a control group. Both groups underwent a neuropsychological evaluation before and after the intervention. Subjects in the intervention group performed physical exercise 3 times a week, 50 min each session. The subjects in the control group did not perform any type of physical exercise and completed their daily life activities. The intervention group improvement in cognitive functions after the intervention and obtained higher scores against the control group. Regular physical exercise improves global cognitive function, visoconstructive capacity, and memory functions.
