Environmental impact of disposable face masks: degradation, wear, and cement mortar incorporation.

Environ Sci Pollut Res Int

January 2025

CERENA - Civil Engineering Research and Innovation for Sustainability, IST-ID, Av. António José de Almeida 12, 1049-001, Lisbon, Portugal.

Polypropylene (PP) disposable face masks (DFMs) are essential for limiting airborne infectious diseases. This study examines the behavior of DFMs under three scenarios: (i) exposure to the natural environment, (ii) simulated high-energy aquatic environments through an abrasion test, and (iii) incorporation into cement-based mortars. In the natural weathering experiment, after 117 days, the DFMs exhibited photodegradation, resulting in chemical alterations in carbonyl and hydroxyl groups.

Parkinson's disease (PD) is a multifactorial neurodegenerative disease that is characterized by the degeneration of dopaminergic neurons in the substantia nigra pars compacta and by the anomalous accumulation of α-synuclein aggregates into Lewy bodies and Lewy neurites. Research suggests 2 distinct subtypes of PD: the brain-first subtype if the pathology arises from the brain and then spreads to the peripheral nervous system (PNS) and the body-first subtype, where the pathological process begins in the PNS and then spreads to the central nervous system. This review primarily focuses on the body-first subtype.

Glia are increasingly appreciated as serving an important function in the control of sleep and circadian rhythms. Glial cells in Drosophila and mammals regulate daily rhythms of locomotor activity and sleep as well as homeostatic rebound following sleep deprivation. In addition, they contribute to proposed functions of sleep, with different functions mapping to varied glial subtypes.

J Neurol

January 2025

Laboratory of Clinical Pharmacology and Therapeutics, Faculdade de Medicina, Universidade de Lisboa, Av. Prof. Egas Moniz, 1649-028, Lisbon, Portugal.

Background: Drooling, defined as the unintentional loss of saliva from the anterior oral cavity, remains poorly understood in terms of the underlying clinical factors in people with Parkinson's disease (PwP). This study aims to clarify these factors by analyzing predictors and secondarily the correlates with the severity of drooling in PwP.

Methods: We conducted a cross-sectional study involving 42 PwP with drooling and 59 without drooling.

Exposure to multiple adverse childhood experiences (ACEs) is a risk factor for the development and increase in somatization symptoms among adolescents. Defense mechanisms and dissociation may play a key role in the association between these variables. The aim of the study was to analyze the indirect association between direct and indirect exposure to ACEs with somatization symptoms through defense mechanisms and dissociation symptoms in Faroese adolescents.

The coordination compounds featuring a {CuO} core, typically bridged by hydroxo or alkoxo groups, are particularly intriguing due to their notable magnetic properties and catalytic activity. In this study, we explored the synthesis and characterization of four new Schiff base ligands and their subsequent complexation with Cu salts, which resulted in the formation of three tetranuclear complexes: [Cu(L)]·2HO (1), [Cu(L)(HL)](Cl)(NO)·5HO (2), and [Cu(L)] (3), as well as one dinuclear complex: [Cu(L)] (4). These tetranuclear complexes all feature a {CuO} core, but with differing coordination environments around the Cu centers.

Due to the aging population, focusing on healthy aging has become a global priority. Cardiovascular diseases (CVDs) and frailty, characterized by increased vulnerability to adverse stress and health events, interact synergistically in advanced age. In older adults, hip fractures are a frequent dramatic "life-transition" event.

Structural, architectural, contractile or electrophysiological alterations may occur in the left atrium (LA). The concept of LA cardiopathy is supported by accumulating scientific evidence demonstrating that LA remodeling has become a cornerstone diagnostic and prognostic marker. The structure and the function of LA and left atrial appendage (LAA) which is an integral part of the LA, are key elements for a better understanding of multiple clinical conditions, most notably atrial fibrillation (AF), cardioembolism, heart failure and mitral valve diseases.

Topical Application onto the Eyelid Skin: Is it a Feasible Delivery Route of Ophthalmic Drugs?

Mini Rev Med Chem

January 2025

Research Institute for Medicines (imed), Faculty of Pharmacy, Universidade de Lisboa, Avenida Professor Gama Pinto, 1649-003 Lisboa, Portugal.

Topical application of ophthalmic drugs remains to be the preferred delivery method. Eye drops lead the pharmaceutical forms due to ease of application. Despite the poor bioavailability of drugs administered topically, especially related to the dilution and excretion by tear fluid, the absence of controlled drug delivery, and the poor compliance within pediatric and senior populations, eye drops and ointments are still the first choices in eye--related disorders management.

Appetite, as the internal drive for food intake, is often dysregulated in a broad spectrum of conditions associated with over- and under-nutrition across the lifespan. Appetite regulation is a complex, integrative process comprising psychological and behavioral events, peripheral and metabolic inputs, and central neurotransmitter and metabolic interactions. The microbiota-gut-brain axis has emerged as a critical mediator of multiple physiological processes, including energy metabolism, brain function, and behavior.

Cryogenic, but not hypothermic, preservation disrupts the extracellular matrix of cell sheets.

Bioact Mater

April 2025

3B's Research Group, I3Bs - Research Institute on Biomaterials, Biodegradables and Biomimetics, University of Minho, Headquarters of the European Institute of Excellence on Tissue Engineering and Regenerative Medicine, AvePark, Parque de Ciência e Tecnologia, Rua Ave 1, Edifício 1 (Sede), 4805-694 Barco, Guimarães, Portugal.

Cell sheet (CS)-based approaches hold significant potential for tissue regeneration, relying on the extracellular matrix (ECM) for success. Like in native tissues, the ECM provides structural and biochemical support for cellular homeostasis and function. Effective preservation strategies that maintain ECM integrity are critical to enhance the therapeutic potential of CS-based approaches.

Background: The Japanese Beetle, Newman, 1838 (Coleoptera, Rutelidae), is a univoltine agricultural pest that poses a serious threat to various agricultural crops. For more than 16 years, the Azorean official authorities have implemented a Long-Term Ecological Research (LTER) programme that is crucial for understanding the dynamics of insect pests, such as the Japanese Beetle, and their impacts on agricultural ecosystems. The significance of this long-term monitoring extends beyond understanding the pest's life cycle.
