It has been suggested that salivary flow rate decreases with age. As is known, the presence of a thin salivary film layer is essential for the comfort of the mucosa beneath a denture base and for denture retention. The purpose of this study was to determine the flow rates, viscosity and the pH of resting and stimulated whole saliva before and after prosthetic treatment in complete denture wearing patients. Saliva was collected under clinical conditions between 08.00 and 10.00 hours. The flow rates of whole saliva were measured at three stages: (i) resting and stimulated saliva before prosthetic treatment; (ii) immediately after the first wearing of the complete denture; and (iii) resting and stimulated saliva after 2 or 3 months of wearing the complete denture. Saliva production was stimulated by chewing paraffin wax. Flow rate was calculated as collected volume/collection time. It was found that there was a significant difference between resting and stimulated whole salivary flow rates before and after complete denture wearing.

Background: Accumulation of β-amyloid (Aβ) in the brain is a hallmark of Alzheimer's Disease (AD). Cerebral deposition of Aβ initiates deteriorating pathways which eventually can lead to AD. However, the exact mechanisms are not known.

Resting natural killer (NK) cells display immediate effector functions after recognizing transformed or infected cells. The environmental nutrients and metabolic requirements to sustain these functions are not fully understood. Here, we show that NK cells rely on the use of extracellular pyruvate to support effector functions, signal transduction and cell viability.

Background: Physical exercise improves overall brain health, cognition, and stimulates the release of extracellular vesicles (EVs) in humans. Exercise upregulates irisin, a myokine derived from fibronectin type III domain-containing protein 5 (FNDC5) previously shown to mediate the beneficial actions of exercise on memory in mouse models of Alzheimer's disease (AD). Here, we investigated if physical exercise upregulates EVs.

Background: Microglia, the innate immune cells of the brain, are a principal player in Alzheimer's Disease (AD) pathogenesis. Their surveillance of the brain leads to interaction with the protein aggregates that drive AD pathogenesis, most notably Amyloid Beta (Aβ). Aβ can elicit attempts from microglia to clear and degrade it using phagocytic machinery, spurring damaging neuroinflammation in the process.
