Dental Pulp Stem Cells Derived from Wisdom Teeth as Multitarget Biological Modulators of Alzheimer’s and Parkinson’s Disease: Mechanistic Insight and Translational Perspective
Abstract: Alzheimer’s disease and Parkinson’s disease are chronic, progressive neurodegenerative disorders with complex pathogenic pathways such as neuroinflammation, oxidative stress, mitochondrial dysfunction, synaptic degeneration, and reduced neurotrophic signalling. Despite the large amount of research, the pharmacological treatments in use offer only symptomatic relief and cannot significantly prevent or slow down disease progression sufficiently; new pathogenetic treatment strategies are necessary. In recent years, stem cell-based approaches have gained interest as potential therapeutic …

Polypropylene Fibres in Cementitious Composites: A Critical Review of Polymer Structure, Processing, Interfacial Behaviour and Performance
Abstract: Polypropylene (PP) fibres are widely used as secondary reinforcement in cementitious composites, yet their performance is governed as much by polymer structure and interfacial chemistry as by dosage. This review synthesises 50 primary sources (2003-2025, concentrated post-2015) to examine how PP molecular structure, fibre-manufacturing history, morphology, surface properties and environmental ageing govern fibre-matrix interaction and multiscale composite performance. Isotacticity, molecular weight, crystallinity and drawing ratio are shown to set the …

Food Packaging Chemicals and Human Health: Molecular Toxicity, Exposure Pathways, and Regulatory Perspectives
Abstract: Food packaging plays a vital role in preserving food quality, extending shelf life, and ensuring safe transportation. However, increasing evidence indicates that chemicals from packaging materials can migrate into food during processing, storage, and consumption, resulting in chronic human exposure. Several food packaging chemicals, including bisphenols, phthalates, per- and polyfluoroalkyl substances (PFAS), styrene, heavy metals, and non-intentionally added substances (NIAS), have emerged as important xenobiotics due to their potential adverse …
