Multivariate synthesis optimization, comprehensive characterization, and surface ligand determination of palladium nanoparticles

We present a high-throughput approach for synthesizing palladium nanoparticles (PdNPs), which are widely used as catalysts in industrial processes, employing an aqueous reaction medium and a commercial reaction platform that enables parallel reactions under identical conditions....

Time-reversal symmetric quadratic differential systems having an invariant cylinder: global dynamics and mechanical application

Abstract This paper provides a comprehensive analysis of the global dynamics and an exact mechanical application for a class of time-reversal symmetric quadratic differential systems in $$\mathbb {R}^{3}$$ R 3 having an elliptic cylinder as an invariant algebraic surface. A norma...

Gonad Status, Condition Index and Biochemical Composition of the Yellow Clam Amarilladesma mactroides

The yellow clam, Amarilladesma mactroides, is an abundant component of the intertidal infauna of the southwestern Atlantic Ocean and an important source of food and income for local communities. In recent years, this species has been increasingly affected by anthropogenic and env...

Twisted Steinberg algebras, regular inclusions and induction

Given a field \mathbb{K} and an ample (not necessarily Hausdorff) groupoid G , we define the concept of a line bundle over G inspired by the well-known concept from the theory of C*-algebras. If E is such a line bundle, we construct the associated twisted Steinberg algebra in ter...

Multidrug-Resistant Bacteria in South Atlantic Cetaceans over a Decade of Surveillance

This decade-long surveillance study (2016–2025) investigates the acquisition of multidrug-resistant (MDR) bacteria in South Atlantic cetaceans to evaluate how ecological niches modulate exposure to biological pollution. Analyzing clinical isolates from stranded cetacean carcasses...

Spatial overlap between cetaceans and gillnet fisheries in Southeastern Brazilian waters and implications for bycatch mitigation

Abstract Human activities threaten marine mammal populations, with bycatch in gillnet fisheries being a major concern. To investigate interactions between fisheries and cetaceans and guide effective management, integrative approaches combining spatial and ecological information a...

Synchronous human-dolphin foraging increases fishing success despite prey unpredictability

Abstract Foraging theory predicts that individuals adjust their behaviour in response to environmental conditions and prey availability. One solution to finding and capturing unpredictable prey is social foraging, yet it remains unclear whether its benefits arise from behavioural...

Behavior change support in the new era of obesity care

Evidence of the effectiveness of glucagon-like peptide-1 receptor agonists (GLP-1 RAs) to improve cardiometabolic health has increased rapidly, as has patient and public demand. This has, and continues to, reshape clinical practice and public health priorities. The World Health O...

Ultrasound-based prediction of fetal hyperinsulinemia: development of a fetal metabolic score

OBJECTIVES: Gestational diabetes mellitus (GDM) is associated with fetal hyperinsulinemia, excessive adiposity, and adverse perinatal outcomes; sonographic markers of fetal adiposity, liver enlargement, and septal thickening may allow direct assessment of fetal metabolic adaptati...

Factors associated with discordance between the patient-reported Rheumatoid Arthritis Disease Activity Index (RADAI) and the Simplified Disease Activity Index (SDAI) concerning the achievement of treat-to-target goals – data from the REAL study

Abstract Background Treat-to-target (T2T) strategies in rheumatoid arthritis (RA) rely on regular assessment of disease activity using validated composite indices, with remission or low disease activity as therapeutic goals. The Simplified Disease Activity Index (SDAI) is widely...

Performance measurement and cross-functional cooperation: serial mediation of reciprocity and commitment

Purpose In social exchange theory (SET), intraorganizational social relationships are formed with the expectation of reciprocal benefits, reinforced by the support and efforts of those involved. This study aims to examine the serial mediation of reciprocity and commitment in the...

Grassland destruction causes shifts in plant traits that persist during recovery

Old-growth grasslands assemble over millennia and support high biodiversity and many ecosystem services, but continue to undergo widespread destruction for production of crops, timber, and minerals. How biodiversity recovers after grassland destruction and the functional conseque...

Pediatric Use of Off‐Label Medicines and Nonevidence‐Based Supplements for COVID ‐19: Findings From the 2015 Pelotas Birth Cohort Study (Brazil)

ABSTRACT Purpose Pediatric off‐label medicine use increased during the COVID‐19 pandemic, exposing children to nonevidence‐based treatments. We described the use of nonevidence‐based COVID‐19 medicines and supplements among children from the 2015 Pelotas Birth Cohort, according t...

Integrating sequencing batch hybrid membrane bioreactor with ozonation for treatment of tissue paper wastewater

Abstract This study assessed the performance of a sequencing batch hybrid membrane bioreactor (SB-HMBR) coupled with ozonation for the treatment of tissue paper wastewater. The SB-HMBR was operated for 90 d with a cycle time of 8.5 h under two aeration intensities, corresponding...

An Evidence-Level Framework for Evaluating Enzyme-Mediated Plastic and Microplastic Transformation

Microbial enzymes have attracted considerable attention as biocatalysts for plastic transformation, yet the experimental evidence supporting reported biodegradation varies substantially in quality and interpretation. Surface-sensitive techniques, molecular-weight analyses, identi...

DOPAL links dopamine dysregulation to neurodegeneration: a translational systematic review and meta-analysis

3,4-Dihydroxyphenylacetaldehyde (DOPAL) is the most reactive dopamine (DA)-derived aldehyde and has been implicated in selective dopaminergic neurodegeneration in α-synucleinopathies, including Parkinson’s disease (PD) and multiple system atrophy (MSA). Here, we present the first...

Discontinuous Peripheral Punctate Echogenic Foci in Thyroid Nodules: A New Sonographic Pattern Suggestive of Papillary Carcinoma

Background: Ultrasound risk stratification systems for thyroid nodules worldwide describe different types of echogenic foci, including punctate echogenic foci (microcalcifications), coarse internal calcifications, and peripheral (rim) calcifications (complete or incomplete), with...

A lean-based method for patient journey improvement: enhancing value and performance in healthcare delivery

Purpose This research introduces a lean-based method, from the customer’s perspective, aimed at continuously improving the sequence of value and non-value stages throughout the purchase journey, named the ideal customer journey method (ICJM). Design/methodology/approach The ICJM...

Learning Domains for Undergraduate Dental Behaviour Support: The BeSiDe Curriculum Learning Outcomes

OBJECTIVES: Dental Behaviour Support (DBS) refers to informal and formal strategies and interventions that support patients' acceptance and experience of oral healthcare. DBS plays a crucial role, particularly for vulnerable groups, yet training across dental curricula remains in...

Towards Hybrid Blockchain Integrated With IoT Applied for Supply Chain Tracking

ABSTRACT Background Preserving the quality and safety of perishable products requires continuous monitoring and reliable traceability. Although the Internet of Things (IoT) enables real‐time data collection, multi‐organizational supply chains lack a common mechanism for assigning...
