A proposal of a fecal scoring system based on physicochemical analyses of suckling pig feces.

Porcine Health Manag

January 2025

Departament de Sanitat i Anatomia Animals, Facultat de Veterinària, Campus de la Universitat Autònoma de Barcelona (UAB), 08193, Bellaterra, Barcelona, Spain.

Background: Digestive disorders are one of the main health problems in suckling piglets. The correct visual identification of feces in suckling piglets is an important tool for the diagnosis of enteric diseases. The aim of the present observational study was to analyze different physicochemical parameters of the feces of suckling piglets aged 0 to 21 days: visual appearance (color and consistency), fecal dry matter (FDM) content and pH.

As global fertilizer application rates increase, high-quality datasets are paramount for comprehensive analyses to support informed decision-making and policy formulation in crucial areas such as food security or climate change. This study aims to fill existing data gaps by employing two machine learning models, eXtreme Gradient Boosting and HistGradientBoosting algorithms to produce precise country-level predictions of nitrogen (N), phosphorus pentoxide (PO), and potassium oxide (KO) application rates. Subsequently, we created a comprehensive dataset of 5-arcmin resolution maps depicting the application rates of each fertilizer for 13 major crop groups from 1961 to 2019.

Surpassing protein specificity in biomimetics of bacterial amyloids.

Int J Biol Macromol

January 2025

Centro de Investigación Biomédica en Red de Bioingeniería, Biomateriales y Nanomedicina, Instituto de Salud Carlos III, Barcelona, Spain; Departament de Genètica i de Microbiologia, Universitat Autònoma de Barcelona, Barcelona, Spain; Institut de Recerca Sant Pau (IR SANT PAU), 08041 Barcelona, Spain. Electronic address:

In nature, nontoxic protein amyloids serve as dynamic, protein-specific depots, exemplified by both bacterial inclusion bodies and secretory granules from the endocrine system. Inspired by these systems, chemically defined and regulatory-compliant artificial protein microgranules have been developed for clinical applications as endocrine-like protein repositories. This has been achieved by exploiting the reversible coordination between histidine residues and divalent cations such as Zn, that promotes protein-protein interactions.

Attention-deficit/hyperactivity disorder (ADHD) presents with symptoms like impulsiveness, inattention, and hyperactivity, often affecting children's academic and social functioning. Non-pharmacological interventions, such as digital cognitive therapy, are emerging as complementary treatments for ADHD. The randomized controlled trial explored the impact of an AI-driven digital cognitive program on impulsiveness, inattentiveness, and neurophysiological markers in 41 children aged 8-12 with ADHD.

Aims: Secondary mitral regurgitation (SMR) and tricuspid regurgitation (TR) are the most common valvular heart diseases in patients with heart failure (HF). Transcatheter edge-to-edge repair (TEER) devices designed for treating MR and TR have been successfully tested in randomized controlled trials, but methodological issues have often challenged their interpretation. This manuscript aimed to provide an overview of TEER registries on SMR and TR in HF, highlighting their key features, describing clinical characteristics and outcomes of patients receiving these devices, and exploring the available data limitations.

The most severe form of male infertility is idiopathic non-obstructive azoospermia (NOA), a complete sperm absence in the ejaculate. We performed exome sequencing in the Croatian infertile brothers with NOA and found a variant in DMRT1 (Doublesex and mab-3 related transcription factor 1) gene that was further assessed by the EMSA assay and molecular dynamic simulations. We additionally screened for DMRT1 mutations in 1940 infertile men diagnosed with spermatogenic failure, 644 normozoospermic controls, and 105 females with primary ovarian insufficiency (POI) recruited to the GEnetics of Male INfertility Initiative (GEMINI) or Estonian Andrology (ESTAND) cohorts.

Background: In this study we investigate the selective compensation of paired peripheral nerves in healthy humans, focusing on distinct axonal conduction velocities in different fibre types. Using paired associative stimulation (PAS) with adjustable parameters, we aimed to modulate and compensate for neuronal activity along the median nerve.

Methods: Six healthy volunteers (3 male, 3 female, aged: 22-49) participated in the current study.

EBV-specific T-cell immunity: relevance for multiple sclerosis.

Front Immunol

January 2025

Department of Neurology with Institute of Translational Neurology, University Hospital Münster, Münster, Germany.

Genetic and environmental factors jointly determine the susceptibility to develop multiple sclerosis (MS). Improvements in the design of epidemiological studies have helped to identify consistent environmental risk associations such as the increased susceptibility for MS following Epstein-Barr virus (EBV) infection, while biological mechanisms that drive the association between EBV and MS remain incompletely understood. An increased and broadened repertoire of antibody and T-cell immune responses to EBV-encoded antigens, especially to the dominant CD4 T-cell EBV nuclear antigen 1 (EBNA1), is consistently observed in patients with MS, indicating that protective EBV-specific immune responses are deregulated in MS and potentially contribute to disease development.

A Post-Mortem Molecular Damage Profile in the Ancient Human Mitochondrial DNA.

Mol Ecol Resour

January 2025

Research Group in Biological Anthropology, Biological Anthropology Unit, Department of Animal Biology, Vegetal Biology and Ecology, Universitat Autònoma de Barcelona, Barcelona, Spain.

Mitochondrial DNA (mtDNA) analysis is crucial for understanding human population structure and genetic diversity. However, post-mortem DNA damage poses challenges, that make analysis difficult. DNA preservation is affected by environmental conditions which, among other factors, complicates the differentiation of endogenous variants from artefacts in ancient mtDNA mix profiles.

Witnessing rejection against one's group can have similar impacts on psychological distress and aggression as experiencing rejection personally. In this study, we investigated the neural activity patterns of group rejection and whether they resemble those of personal-level rejection. We first identified the neural correlates of social rejection (exclusion based on negative attention) compared with ostracism (exclusion based on lack of social connection) and then compared group-level to personal-level rejection.

Small fetuses, with estimated fetal weight (EFW) below the tenth percentile, are classified as fetal growth restriction (FGR) or small for gestational age (SGA) based on prenatal ultrasound. FGR fetuses have a greater risk of stillbirth and perinatal complications and may benefit from serial ultrasound scans to guide early delivery. Abnormal serum angiogenic factors, such as the soluble fms-like tyrosine kinase-1 (sFlt-1):placental growth factor (PlGF) ratio, have shown potential to more accurately distinguish FGR from SGA, with fewer false positives.

Fiber is essential for rumen health, microbial fermentation, and the energy supply of herbivores. Even though the study of fecal fiber contents (neutral detergent fiber NDF, acid detergent fiber ADF, and acid detergent lignin ADL) using near-infrared reflectance spectroscopy (NIRS) has allowed investigating nutritional ecology of different herbivore species, NIRS calibrations are species-specific and require a large number of samples for predictions. A multispecies calibration would be an advantage since samples from different herbivores could be used to calibrate a model capable of predicting the fecal fiber content of other herbivores.
