UNLABELLED There are few published studies on the effects of protein-caloric undernourishment on the oral mucosa. OBJECTIVES The objective of this study is to verify the histological and ultrastructural aspects of the tongue mucosa in protein-caloric undernourished adult rats. MATERIAL AND METHODS A clinical experimental study was done in thirty Wistar rats, 15 controls and 15 with protein-...

We used mice deficient in dopamine beta-hydroxylase [Dbh(-/-)] and their littermate controls [Dbh(+/-)] to examine the role of epinephrine (Epi) and norepinephrine (NE) in the maintenance of cardiovascular parameters during 7 days of caloric restriction and acute exposure to environmental stress. Cardiovascular parameters of the mice were monitored using blood pressure radiotelemeters at an amb...

Introduction: Fasting, like Islamic Ramadan Fasting, has been associated with health benefits. Islamic Ramadan fasting, a form of caloric restriction (CR) or alternate day fasting that. Studies suggest a comparable effect of ADF and caloric restriction. Despite the fact that fasting can be considered as a form of dietary restriction, fasters tend to have difficulty to reduce their food intake d...

This brief study investigates the extent and origin of the apparent dependency of air delivery speculum size on the effectiveness of air used as a stimulus in the bi-thermal caloric test, using water as a reference stimulus. Eleven normal volunteers served as subjects. Six caloric stimulus delivery conditions included air with two speculum sizes, speculum only and with a rubber tube extension, ...

Positron emission tomography (PET) was used to demonstrate temporary down-regulation of visual cortex activities associated with eye movements. The aim of the present study was to test this paradigrn with visual evoked potentials CVE?s) in the visual cortex of 7 healthy human subjects during caloric nystagmus. Caloric stimulation was perfbrmed by inigating the right or left extemal ear canals w...
