Influence of agarose in semi-IPN hydrogels for sustained Polymyxin B release.

Hydrogels (HGs) are 3-D polymeric networks with high water content, making them appropriate for biomedical applications such as drug delivery systems. This study examines the impact of agarose in semi-interpenetrating polymer networks (Semi-IPNs) based on poly(acrylic acid) (p(AA)), N, N' Methylenebis(acrylamide) (MBA) and agarose (AGA) on the sustained release of Polymyxin B (PolB). Agarose incorporation improved the mechanical strength, swelling behavior and drug retention capacity of the HG.

Identification of the Emerging C1-like Lineage of Enterovirus A71 in Two Uruguayan Children with Hand-Foot-and-Mouth Disease and Neurological Complications.

Enterovirus A71 (EV-A71) is a major cause of hand-foot-and-mouth disease (HFMD), particularly in cases that involve complications affecting the nervous system or cardiopulmonary function. In South America, EV-A71 has primarily been identified through studies of acute flaccid paralysis (AFP) and other neurological disorders. In September 2022, two children from a small city in Uruguay were hospitalized with presumptive rhombencephalitis, exhibiting symptoms of HFMD.

Macrophages and the Extracellular Matrix.

Macrophages are critical to the immune response, serving multiple essential roles in maintaining tissue homeostasis and providing immune protection. These cells also interact with and influence the extracellular matrix (ECM) by sensing and responding to its components. Such interactions between macrophages and the ECM are mediated through the secretion and uptake of various biomacromolecules, such as cytokines and the extracellular vesicles, including exosomes and microvesicles.

Development of a + Cardiac Mouse Progenitor Immortalized Model to Unravel the Relationship with Its Protective Vascular Endothelial Niche.

The adult mammalian heart has been demonstrated to be endowed with low but real turnover capacity, especially for cardiomyocytes, the key functional cell type. The source, however, of that turnover capacity remains controversial. In this regard, we have defined and characterized a resident multipotent cardiac mouse progenitor population, +DR (for + Damage-Responsive cells).

Signature of anyonic statistics in the integer quantum Hall regime.

Anyons are exotic low-dimensional quasiparticles whose unconventional quantum statistics extend the binary particle division into fermions and bosons. The fractional quantum Hall regime provides a natural host, with the first convincing anyon signatures recently observed through interferometry and cross-correlations of colliding beams. However, the fractional regime is rife with experimental complications, such as an anomalous tunneling density of states, which impede the manipulation of anyons.

DarwinGSE: Towards better image retrieval systems for intellectual property datasets.

A trademark's image is usually the first type of indirect contact between a consumer and a product or a service. Companies rely on graphical trademarks as a symbol of quality and instant recognition, seeking to protect them from copyright infringements. A popular defense mechanism is graphical searching, where an image is compared to a large database to find potential conflicts with similar trademarks.

Late-Presenting Eosinophilic Granulomatosis with Polyangiitis as Cause of Pulmonary Fibrosis: A Case-Based Review.

Introduction: Eosinophilic granulomatosis with polyangiitis (eGPA) is a necrotising vasculitis of small and medium calibre vessels, which affects mostly patients in their fourth to sixth decade of life, and it is a very uncommon aetiology for pulmonary fibrosis.

Clinical Case: A Hispanic 72-year-old female patient presents with a history of lower extremities pain, paraesthesia, oedema, and occasional macroscopic haematuria. During her hospitalisation, the patient presents, and images showed findings compatible with pulmonary fibrosis and alveolar haemorrhage, which require a biopsy, establishing the diagnosis of an eGPA.

Sensory, emotional, and appropriateness of plant- and meat-based burgers.

The plant-based meat alternative market is experiencing rapid growth. However, whether this growth extends to mainstream consumers will depend on the sensory profile, emotional profile, and situational appropriateness of these products. This study provides a sensory comparison between two plant-based burgers, one hybrid burger, and a conventional 100% ground beef burger.

Earth at risk: An urgent call to end the age of destruction and forge a just and sustainable future.

Human development has ushered in an era of converging crises: climate change, ecological destruction, disease, pollution, and socioeconomic inequality. This review synthesizes the breadth of these interwoven emergencies and underscores the urgent need for comprehensive, integrated action. Propelled by imperialism, extractive capitalism, and a surging population, we are speeding past Earth's material limits, destroying critical ecosystems, and triggering irreversible changes in biophysical systems that underpin the Holocene climatic stability which fostered human civilization.

Perceived usefulness of the nurse-patient therapeutic relationship in the rehabilitation journey of people with urinary incontinence: A mixed-method study.

Introduction: Despite various studies on the impact of incontinence on patients' lives, the existing literature has not investigated the contribution of nursing care during rehabilitation in terms of quality of life. Fewer data, therefore, exist on the characteristics and perceived impact of the therapeutic relationship as part of the rehabilitation program.

Aims: To investigate the characteristics of the nurse-patient therapeutic relationship and its impact throughout the rehabilitation program; to describe the levels of patient burden on everyday activities.

Effects of herbicides and fertilization on biofilms of Pampean lotic systems: A microcosm study.

We experimentally assessed the impact of the application of herbicides and fertilizers derived from agricultural activity through the individual and simultaneous addition of glyphosate, atrazine, and nutrients (nitrogen 'N' and phosphorus 'P') on the biofilm community and their resilience when the experimental factors were removed. We hypothesize that i) the presence of agrochemicals negatively affects the biofilm community leading to the simplification of the community structure; ii) the individual or simultaneous addition of herbicides and nutrients produces differential responses in the biofilm; and iii) the degree of biofilm recovery differs according to the treatment applied. Environmentally relevant concentrations of glyphosate (0.
