"Pathway Leap": A New Molecular Phenomenon to Consider in the Pathogenesis of Melanocytic Tumors.

Introduction: The current WHO classification of melanocytic tumors distinguishes 9 pathogenic routes. This classification is based on the conceptual interpretation that melanocytic tumors evolve from benign counterparts, accumulating mutations, eventually developing into melanomas with metastatic and potentially lethal capacity. In this article, we present a molecular study of 2 melanocytic tumors that suggest a "leap" from pathogenic routes IV to I.

No Obesity Paradox for Health-Related Quality of Life in Patients with Heart Failure and Reduced Ejection Fraction: Insights from the VIDA Multicenter Study.

Previous studies showed that, paradoxically, obese patients with heart failure (HF) have better clinical outcomes compared to overweight, normal, or underweight patients. Scientific societies emphasize the importance of integrating quality of life (QoL) assessment in cardiovascular care. However, the association between QoL and weight remains understudied.

Design: Descriptive cross-sectional observational study.

Setting: University Podiatry Clinic at the University of A Coruña (CUP-UDC), Spain.

Two Cases of FAVA With an Uncommon Localization in Adults.

The fibroadipose vascular anomaly (FAVA) is a relatively unknown vascular anomaly in the realm of adult dermatopathology. Despite its intramuscular location, dermatologists often encounter cases, approaching them surgically under the presumption of a potential lipoma. This entity was first described in 2014, and consequently, many FAVA cases may be concealed in our archives under diagnoses of other entities that require differential diagnoses, such as intramuscular fast-flow vascular anomaly.

Computer-assisted evaluation of retinal vessel tortuosity in children with sickle cell disease without retinopathy.

Objective: We assessed the predictive efficacy of automatically quantified retinal vascular tortuosity from the fundus pictures of patients with sickle cell disease (SCD) without evident retinopathy.

Methods: Retinal images were obtained from 31 healthy and 31 SCD participants using fundus imaging and analyzed using a novel computational automated metric assessment. The local and global vessel tortuosity and their relationship with systemic disease parameters were analyzed based on the images.

Bioconversion of pure CO to caproic acid with zero valent iron: Optimizing carbon flux distribution in co-cultures of Acetobacterium woodii and Megasphaera hexanoica.

Acetobacterium woodii and Megasphaera hexanoica were co-cultured for caproic acid (CA) production from lactic acid (LA) and CO. Also, various concentrations (1 g/L, 3 g/L, 5 g/L, and 10 g/L) of Zero Valent Iron (ZVI) were supplied to study its impact on the co-culture system. In flask experiments, 10 g/L LA and 1.

Objectives and achievements of the HUMN project on its 26th anniversary.

Micronuclei (MN) are a nuclear abnormality that occurs when chromosome fragments or whole chromosomes are not properly segregated during mitosis and consequently are excluded from the main nuclei and wrapped within nuclear membrane to form small nuclei. This maldistribution of genetic material leads to abnormal cellular genomes which may increase risk of developmental defects, cancers, and accelerated aging. Despite the potential importance of MN as biomarkers of genotoxicity, very little was known about the optimal way to measure MN in humans, the normal ranges of values of MN in healthy humans and the prospective association of MN with developmental and degenerative diseases prior to the 1980's.

International Society for Heart and Lung Transplantation Guidelines for the Evaluation and Care of Cardiac Transplant Candidates-2024.

The "International Society for Heart and Lung Transplantation Guidelines for the Evaluation and Care of Cardiac Transplant Candidates-2024" updates and replaces the "Listing Criteria for Heart Transplantation: International Society for Heart and Lung Transplantation Guidelines for the Care of Cardiac Transplant Candidates-2006" and the "2016 International Society for Heart Lung Transplantation Listing Criteria for Heart Transplantation: A 10-year Update." The document aims to provide tools to help integrate the numerous variables involved in evaluating patients for transplantation, emphasizing updating the collaborative treatment while waiting for a transplant. There have been significant practice-changing developments in the care of heart transplant recipients since the publication of the International Society for Heart and Lung Transplantation (ISHLT) guidelines in 2006 and the 10-year update in 2016.

Toxicity of zinc oxide nanoparticles: Cellular and behavioural effects.

Due to their extensive use, the release of zinc oxide nanoparticles (ZnO NP) into the environment is increasing and may lead to unintended risk to both human health and ecosystems. Access of ZnO NP to the brain has been demonstrated, so their potential toxicity on the nervous system is a matter of particular concern. Although evaluation of ZnO NP toxicity has been reported in several previous studies, the specific effects on the nervous system are not completely understood and, particularly, effects on genetic material and on organism behaviour are poorly addressed.

European Society for Organ Transplantation (ESOT) Consensus Statement on the Use of Non-invasive Biomarkers for Cardiothoracic Transplant Rejection Surveillance.

While allograft rejection (AR) continues to threaten the success of cardiothoracic transplantation, lack of accurate and repeatable surveillance tools to diagnose AR is a major unmet need in the clinical management of cardiothoracic transplant recipients. Endomyocardial biopsy (EMB) and transbronchial biopsy (TBBx) have been the cornerstone of rejection monitoring since the field's incipience, but both suffer from significant limitations, including poor concordance of biopsy interpretation among pathologists. In recent years, novel molecular tools for AR monitoring have emerged and their performance characteristics have been evaluated in multiple studies.

Concordance in bacterial colonization profiles between voice prostheses and oral microbiota post-laryngectomy: An experimental study.

Objective: Knowledge about voice prosthesis microbial colonization is vital in laryngectomized patients' quality of life (QoL). Herein, we aimed to explore the relationship between oral microbial patterns, demographic variables and voice prosthesis performance.

Methods: Thirty laryngectomy patients were assessed for microbial colonization in their voice prostheses and oral cavities.

The relationship between motivation profiles for health-oriented physical activity, basic psychological needs and emotional regulation.

The study of motivation toward health-oriented physical activity helps to know the reasons that guide people to practice physical activity. Moreover, different types and levels of motivation may coexist. As such, this paper aimed to analyze the combination of motivation for health-oriented physical activity profiles and examine whether profiles differed in emotional regulation and basic psychological needs.

Bioaccumulation of trace metals in the plastisphere: Awareness of environmental risk from a European perspective.

The term "Plastisphere" refers to the biofilm layer naturally formed by microorganisms attaching to plastic surfaces. This layer possesses the capability to adsorb persistent organic and inorganic pollutants, particularly trace metals, which are the focus of this research study. Immersion experiments were concurrently conducted in five locations spanning four European countries (France, Ireland, Spain, and Italy) utilising eight distinct polymers.

Cocaine-Induced Plasma Cell Orificial "Dermatomucositis": A More Accurate Descriptive Term for a Clearly Dermatological Entity.

Although the involvement of the nasal passages and nasal septum in cocaine users has been known for decades, a new presentation affecting the nostrils and upper lip with an inflamed appearance has recently been documented. The authors who identified this presentation termed it "cocaine-related plasma cell mucositis" due to the abundance of plasma cells in the infiltrate. In this article, we present a second case and emphasize the dermal involvement of the lip, leading us to consider the condition as a genuine dermatomucositis.

The dermal deposits in the finger of the Holy Roman Emperor Charles I of Spain and V of Germany.

Charles I of Spain and V of Germany was one of the most prominent figures in Christendom. The vast empire ruled by the monarch extended across multiple continents. However, the final years of his life were overshadowed by depression and incapacitating joint degeneration, leading him to retire to the Monastery of Yuste in Cáceres, Spain.

Unlocking the potential of one-carbon gases (CO, CO) for concomitant bioproduction of β-carotene and lipids.

This study investigates the use of a Yarrowia lipolytica strain for the bioconversion of syngas-derived acetic acid into β-carotene and lipids. A two-stage process was employed, starting with the acetogenic fermentation of syngas by Clostridium aceticum, metabolising CO, CO, H, to produce acetic acid, which is then utilized by Y. lipolytica for simultaneous lipid and β-carotene synthesis.

AMWEst, a new thermostable and detergent-tolerant esterase retrieved from the Albian aquifer.

A fosmid library was constructed with the metagenomic DNA from the high-temperature sediment-rich water of the Albian aquifer (Algeria). Functional screening of this library was subsequently done looking for genes encoding lipolytic enzymes. We identified a novel gene named AMWEst (1209 base pairs) encoding a protein of 402 amino acids with a predicted molecular weight of 43.

Effect of miR-21 in mesenchymal stem cells-derived extracellular vesicles behavior.

Background: A challenging new branch of research related to aging-associated diseases is the identification of miRNAs capable of modulating the senescence-associated secretory phenotype (SASP) which characterizes senescent cells and contributes to driving inflammation.

Methods: Mesenchymal stem cells (MSC) from human umbilical cord stroma were stable modified using lentivirus transduction to inhibit miR-21-5p and shotgun proteomic analysis was performed in the MSC-derived extracellular vesicles (EV) to check the effect of miR-21 inhibition in their protein cargo. Besides, we studied the paracrine effect of those modified extracellular vesicles and also their effect on SASP.
