Exercise reduces inhibitory neuroactivity and protects myenteric neurons from age-related neurodegeneration.

The practice of regular exercise is indicated to prevent some motility disturbances in the gastrointestinal tract, such as constipation, during aging. The motility alterations are intimately linked with its innervations. The goal of this study is to determine whether a program of exercise (running on the treadmill), during 6 months, has effects in the myenteric neurons (NADH- and NADPH-diaphorase stained neurons) in the colon of rats during aging.

Burning mouth syndrome (BMS): sialometric and sialochemical analysis and salivary protein profile.

Objective: The aim of the present study was to analyse the characteristics of salivary production and its composition in individuals with burning mouth syndrome (BMS).

Study Design: Salivary flow rate, concentrations of potassium, iron, chloride, thiocyanate, magnesium, calcium, phosphorus, glucose, total protein and urea, as well as the expression profile of salivary proteins were analysed by SDS-PAGE.

Results: The mean salivary flow rate among control patients was lower than that of BMS patients.
