Research on the dental properties of lactitol as a bulk sweetener to replace dietary sugar is reviewed under three headings: microbiological experiments in vitro, investigations in laboratory animals, and studies in man. Lactitol was not easily metabolized by acidogenic and polysaccharide-forming oral micro-organisms, its enamel-demineralizing potential in vitro intra-oral acid development and dental plaque formation from lactitol in man were substantially lower than from sucrose. The indications for dental health benefits are promising.

Coronaviruses continue to disrupt health and economic productivity worldwide. Porcine epidemic diarrhea virus (PEDV) is a devastating swine disease and SARS-CoV-2 is the latest coronavirus to infect the human population. Both viruses display a similar spike protein on the surface that is a target of vaccine development.

They have the same membrane composition and characteristics as primitive cells, which enables them to penetrate cells and tissues efficiently. These OMVs exhibit excellent membrane stability, immunogenicity, safety, and permeability (which makes it easier for them to penetrate into tumour tissue), making them suitable for developing cancer vaccines and drug delivery systems.

Psoriasis, a chronic inflammatory dermatosis, represents a significant clinical challenge due to its complex pathogenesis and the limitations of existing therapeutic strategies. Current psoriasis diagnoses are primarily clinician-dependent, with instrumental diagnostics serving as adjuncts. Ongoing research is progressively deciphering its molecular underpinnings; the future of psoriasis diagnostics may involve genetic and immunological profiling to pinpoint biomarkers, enabling more accurate and timely interventions.

Non-celiac gluten/wheat sensitivity (NCGWS) is a syndrome for which pathogenesis and management remain debated. It is described as a condition characterized by gastrointestinal and extra-intestinal symptoms rapidly occurring after gluten ingestion in subjects who have had celiac disease or wheat allergy excluded. To date, the diagnosis of NCGWS is challenging as no universally recognized biomarkers have been yet identified, nor has a predisposing genetic profile been described.
