There is an open debate on the role of artificial networks to understand the visual brain. Internal representations of images in artificial networks develop human-like properties. In particular, evaluating distortions using differences between internal features is correlated to human perception of distortion.

Usefulness of serum neurofilament light chain in chronic inflammatory demyelinating polyradiculoneuropathy.

J Neurol Sci

January 2025

Neuromuscular Diseases Unit, Department of Neurology, Vall d'Hebron University Hospital, Vall d'Hebron Research Institute, Barcelona, Spain; Department de Medicina, Universitat Autónoma de Barcelona, Barcelona, Spain.

Background: The development of new biomarkers is essential to improve diagnostic accuracy and guide treatment decisions in chronic inflammatory demyelinating polyradiculoneuropathy (CIDP). The aim of this study was to investigate the utility of the serum neurofilament light chain (sNfL) level as a marker for disability and response to immunomodulatory treatment in patients with CIDP.

Methods: This prospective, single-center, observational study included 38 patients with CIDP: 19 treatment-naive (CIDP-I) patients assessed before and after the initiation of immunomodulatory therapy and 19 stable patients on maintenance immunoglobulins (CIDP-M).

January 2025

Área de Críticos, Clínica Universidad de Navarra, Spain. Electronic address:

The intensive care units structure, the technological improvement and the severity of the patients, require that there be harmony between all the actors involved in assisting the critically ill patient. Added to this context is that the current role of the supervisor involves assuming more and more management skills, without losing sight of the need to frame professional practice within the framework of a philosophy of care. Given this challenge for the supervisor, the appearance in our environment of the Advance Practice Nurse figure (APN) is an opportunity.

Conductance oscillations in helicene-based junctions.

J Phys Condens Matter

January 2025

Departamento de Fisica Teórica de la Materia Condensada, Universidad Autonoma de Madrid, Cantoblanco, 28049 Madrid, Madrid, 28049, SPAIN.

We have carried out a theoretical study into electron transport through molecular junctions based on dithiolated helicenes of varying lengths. We found that, in certain specific structural conditions, in which the orientation and the pitch of the helical structures are kept constant, the transmission at the Fermi level as a function of the molecular length exhibits oscillations which approximately follow an odd-even pattern. However, dispersive interactions alter this trend, ensuing a rather different quasi-periodic oscillating pattern with a sawtooth profile.

Cold-temperate and Arctic hard bottom coastal ecosystems are dominated by kelp forests, which have a high biomass production and provide important ecosystem services, but are subject to change due to ocean warming. However, the photophysiological response to increasing temperature of ecologically relevant species, such as Laminaria digitata, might depend on the local thermal environment where the population has developed. Therefore, the effects of temperature on growth rate, biochemical composition, maximum quantum yield, photosynthetic quotient and carbon budget of young cultured sporophytes of Laminaria digitata from the Arctic at Spitsbergen (SPT; cultured at 4, 10 and 16 °C) and from the cold-temperate North Sea island of Helgoland (HLG; cultured at 10, 16 and 22 °C) were comparatively analyzed.

Introduction: Sarcomas are a rare and diverse group of mesenchymal-origin solid tumors, constituting only 1% of adult malignancies and classified into soft tissue and bone sarcomas. For localized disease, surgery and radiotherapy remain the cornerstone treatments. However, systemic options for advanced stages are limited, with an overall survival of approximately 20 months.

This study investigates the nature and interplay of noncovalent interactions (NCIs)─tetrel bonds (TB), hydrogen bonds (HB), and halogen bonds (XB)─in molecular assemblies formed between trifluorogermyl hypochlorite (FGeOCl) and hydrogen cyanide (HCN). Using a combination of high-level computational methods, we explored the geometric, energetic, and electronic properties of dimers, trimers, and tetramers formed in different molar ratios of interacting reagents. Various analyses reveal a significant cooperativity between TB and HB, which mutually reinforce each other, while XB interactions are diminished in the presence of TB and HB.

Background: Menstruation is a physiological process that may be accompanied by pain, headache, edema, emotional changes, and other symptoms, all of which affect quality of life. Although the results of some studies indicate lifestyle habits can affect the menstrual cycle and associated symptoms, few have investigated this issue, and even fewer have explored the impact of these symptoms on quality of life, in Spanish women.

Purpose: The objectives of this study were to determine the prevalence of dysmenorrhea and premenstrual syndrome (PMS) among students at a Spanish university, assess the impact of these conditions on quality of life, and analyze the relationship among lifestyle habits, dysmenorrhea, and PMS.

Adult neurogenesis has most often been studied in the hippocampus and subventricular zone-olfactory bulb, where newborn neurons contribute to a variety of behaviors. A handful of studies have also investigated adult neurogenesis in other brain regions, but relatively little is known about the properties of neurons added to non-canonical areas. One such region is the striatum.

Antigen receptor ITAMs provide tonic signaling by acting as guanine nucleotide exchange factors to directly activate R-RAS2.

Sci Signal

January 2025

Centro de Biología Molecular Severo Ochoa, Consejo Superior de Investigaciones Científicas, Universidad Autónoma de Madrid, 28049 Madrid, Spain.

The small GTPase R-RAS2 regulates homeostatic proliferation and survival of T and B lymphocytes and, when present in high amounts, drives the development of B cell chronic lymphocytic leukemia. In normal and leukemic lymphocytes, R-RAS2 constitutively binds to antigen receptors through their immunoreceptor tyrosine-based activation motifs (ITAMs) and promotes tonic activation of the phosphatidylinositol 3-kinase (PI3K) signaling pathway. Here, we examined the molecular mechanisms underlying this direct interaction and its consequences for R-RAS2 activity.

Climate change is a spatial and temporarily non-uniform phenomenon that requires understanding its evolution to better evaluate its potential societal and economic impact. The value added of this paper lies in introducing a quantitative methodology grounded in the trend analysis of temperature distribution quantiles to analyze climate change heterogeneity (CCH). By converting these quantiles into time series objects, the methodology empowers the definition and measurement of various relevant concepts in climate change analysis (warming, warming typology, warming amplification and warming acceleration) in a straightforward and robust testable linear regression format.

With this document, the European Association of Cardiovascular Imaging (EACVI) provides an Expert Consensus on the role of multi-modality imaging (MMI) in the management of patients with multiple valvular heart disease (MVD). Emphasis is given to the use of MMI to unravel the diagnostic challenges that characterize these patients and to improve risk stratification. Complementing the last European Society of Cardiology and European Association of Cardio-Thoracic Surgery guidelines on valvular heart disease, this Expert Consensus document also outlines how MMI assessment should form an integral part of the multi-disciplinary heart team discussion for patients with MVD to help with complex decision-making regarding the choice and timing of treatment.
