Prevalence and magnitude of muscle loss in the pediatric intensive care unit assessed by ultrasound: a systematic review and meta-analysis

OBJECTIVE: To systematically review and quantify the variation in quadriceps femoris muscle thickness in children admitted to pediatric intensive care units (PICUs) and to identify factors associated with this loss. METHODS: Searches were performed in Cochrane Library, Embase, Pu...

Gene therapy benefits in a small cohort of symptomatic 5q spinal muscular atrophy patients and real world pediatric outcomes

OBJECTIVE: To characterize clinical outcomes of gene replacement therapy administered after symptom onset in a small group of children with 5q spinal muscular atrophy (SMA) and to describe its impact on motor function and supportive care needs in real-world practice. METHODS: Obs...

A Robust Masked Painter Framework for Gene Selection in Binary Classification of High-Dimensional Functional Genomic Data

High-dimensional gene expression datasets in chemometric and biomedical research present significant challenges for machine learning because the number of genes greatly exceeds the number of available samples, increasing the risk of overfitting and reducing classification reliabi...

Impact of calcined clays additions on phase assemblage and mechanical strength of autoclaved low-clinker fiber cement matrices

Calcined clays are promising constituents for use in low-clinker autoclaved fiber cement production. Previous studies on the use of calcined clays in autoclaved fiber cement matrices have shown that their behavior is complex and sometimes counterintuitive. This study investigates...

A systematic review of sustainable geopolymer concrete incorporating coconut fiber and marble powder with emphasis on mechanical performance, durability and optimal replacement levels

This systematic review investigates the use of coconut fiber and marble powder as alternative aggregates in geopolymer concretes, focusing on their mechanical performance and durability. Conducted systematically between July and November 2025, this study analyzed 75 records ident...

Regulation in ecological systems: an organizational approach

The term “regulation” is often used in biology to refer to the means by which a system keeps or returns to a certain state after perturbation. Feedback mechanisms and the propagation of the perturbation through a network of constitutive components are commonly associated with thi...

Benefits of Using Hydroxychloroquine/Chloroquine in the Treatment of Immunomediated Rheumatic Diseases

Antimalarial drugs, particularly hydroxychloroquine (HCQ) and chloroquine (CQ), have been used for decades as cornerstone therapies in the management of immune‑mediated rheumatic diseases (IMRDs). Beyond their classical role in disease activity control, these agents exert pleiotr...

Barriers to occupational health and safety management in micro and small enterprises: a multi-level analysis from a developing country context

Occupational health and safety (OHS) in micro and small enterprises (MSE) remains a critical challenge, given their disproportionate exposure to occupational risks and limited capacity to implement structured health and safety management practices. Although previous studies have...

Adhesion between geopolymer matrix and vegetable fibers: effect of matrix composition and fiber treatment

Seeking to promote sustainable composites composed of a low-carbon matrix and a renewable reinforcement, this study evaluated the fiber–matrix adhesion of sisal fibers used as reinforcement in geopolymeric matrices produced by the alkaline activation of fiber cement waste, in com...

Fuzzy hybrid system based on ensemble learning for classification in intelligent manufacturing processes

Abstract The integration of Machine Learning (ML) into advanced manufacturing is a key enabler of Industry 4.0, supporting intelligent quality control and early fault detection. Despite recent advances, challenges remain regarding the interpretability and adaptability of multicla...

Between Leaves, Prayers, and Healing Hands: A Cross-Regional Scoping Review of Ritual Healers and Plant-Based Community Knowledge

Plant-based healing practices integrate botanical resources, ritual speech, gesture, faith, spiritual mediation, protection, and social recognition within complex community systems of care. This cross-regional scoping review mapped the traceable literature on plant-based knowledg...

Skew-symmetric augmented matrices and a characterization of virtual doodles

Abstract In this paper, we present a brief overview of the concept of doodles from the perspective of J. S. Carter’s work on classifying immersed curves and the work of J. Carter, S. Kamada, and M. Saito on stable equivalence of knots on surfaces and virtual knot cobordisms. We u...

Computational study of the CO$$_2$$ hydrogenation to formic acid catalyzed by a P,P-bidentate copper(I) complex

Terminology in para sport research: is there a “correct” way to speak about disability?

Language used in disability sport reflects societal values and shapes how athletes are perceived. In adapted, Para, and Paralympic contexts, terms are not merely descriptive – they influence identity, inclusion, and respect. Two main approaches are discussed: person-first languag...

Microparticles of greenish-brown propolis extract: phytochemical, physicochemical characterisation and in vitro dissolution profile

The low solubility of propolis in water and its limited bioavailability reduce the effectiveness of bioactive compounds, demonstrating the necessity of techniques that can overcome these limitations. Spray-drying is a promising approach to overcoming these challenges. In this stu...

Tropical-Forest Degradation–Restoration Interface: A Comprehensive Review

Tropical forests sustain exceptional biodiversity and regulate global carbon and water cycles, yet degradation and incomplete recovery increasingly compromise these functions. We integrated bibliometric mapping with structured systematic synthesis to characterize research at the...

Rethinking Plasticity in Sponges

What lies behind the extraordinary phenotypic plasticity of sponges? We used this question to conduct a systematic review of how "phenotypic plasticity" is approached in the literature regarding the phylum Porifera. First, we gathered information on what the literature says about...

Effect of Combined Aerobic and Resistance Training on Exercise Capacity, Muscle Strength, Quality of Life, and Mortality in Patients with Coronary Heart Disease: A Systematic Review with Meta-analysis

CART (combined aerobic and resistance training) has shown important results in exercise-based cardiovascular rehabilitation. However, there are little data concerning the effects of CART on the exercise capacity, muscle strength, health-related quality of life (HRQoL), and mortal...
