Butterflies of the genus Heliconius are well known for their peculiar habits of utilizing pollen as a source of amino acids. Saliva plays a major role in the process of extracting amino acids and proteins from the pollen grains. In this investigation, we obtained samples of saliva from adult Heliconius melpomene by placing pumpkin pollen or fine glass-beads on the proboscis, which stimulates th...

Saliva as a diagnostic tool provides a noninvasive, simple and low-cost method for disease detection and screening. Saliva collection is more practical and comfortable compared with other invasive methods, and saliva can be a desirable body fluid for biomarker detection in clinical applications. The integration of omics methods has allowed accurate detection and quantification of transcripts fo...

The concentration of testosterone in whole saliva is significantly increased (by 9%) after toothbrushing. In ultrafiltrates of saliva collected at the same time as the whole saliva, testosterone concentrations after toothbrushing were unchanged. In 88% of the 162 whole-saliva specimens, but not in the ultrafiltrates, we also measured higher hemoglobin concentrations after toothbrushing. We conc...

Variability of the mixed saliva/plasma theophylline relation was examined in seven children aged 2 to 13 years. Good correlation between plasma and saliva concentrations was found, but on the three occasions there was considerable inter- and intrapatient variability. There was no significant or consistent relation between unstimulated and stimulated saliva concentrations or between saliva conce...

objectives: periodontal pathogens need acidic environments to proliferate in periodontium, and their growth is affected by the salivary flow rate and ph of the mouth. alterations in flow and acidity of saliva have an important effect on oral diseases such as periodontitis. this study was designed to compare salivary ph and flow rate before and after using green tea, black tea and coffee in pati...

this evidence-based article reviews risk indicators and management of unknown-origin xerostomia. xerostomia and hyposalivation refer to different aspects of dry mouth. xerostomia is a subjective sensation of dry mouth, whilst hyposalivation is defined as an objective assessment of reduced salivary flow rate. about 30% of the elderly (65 years and older) experience xerostomia and hyposalivation....

background and aims. cigarette smoke can induce oral cancer by its free radicals and oxidative damage. salivary antioxidants system is believed to have an important role in defense mechanisms against oxidative stress. this study was compared total antioxidant capacity (taoc) of saliva in smokers and nonsmokers. materials and methods. in this cross-sectional study, 30 male smokers with mean age ...

There has been substantial interest in the use of saliva as a diagnostic medium for drugs of abuse because it can be obtained noninvasively. Although drugs of abuse have been investigated in saliva for more than a decade, the role of saliva remains uncertain. A clear picture is difficult to obtain because of variations in (1) the analytical methods used; (2) the dose regimen of subjects, which ...

Bioequivalence of rusovastatin in healthy human volunteers was done using saliva and plasma matrices in order to investigate the robustness of using saliva instead of plasma as a surrogate for bioequivalence of class III drugs according to the salivary excretion classification system (SECS). Saliva and plasma samples were collected for 72 h after oral administration of rusovastatin 40 mg to 12 ...
