Biological markers in nasal secretions provide valuable information on nasal pathophysiology. However, published data on biomarker concentrations in nasal fluids are remarkably inconsistent, and the bias due to different sampling techniques, has not yet been systematically evaluated. Concentrations of various protein were repeatedly determined in nasal secretions of 16 healthy volunteers. The p...
In the hen oviduct, tubules have been identified that preserve the sperm, maintaining viability for up to 15 weeks. This study aimed to evaluate the physiological status of rooster sperm when preserved in vitro with uterus vaginal junction secretions (UVJS). Males and females of the Rhode Island breed were used. Sperm aliquots were prepared using Lake extender and Lake extender with UV...
Neotropical poison frogs sequester alkaloid-based chemical defenses from their diet, which seem to repel invertebrate predators after contact. In this study, we tested the reaction of predatory ants toward skin secretions of captive-bred poison frogs without alkaloids. Although the secretions had a smell and taste similar to those of wild-caught frogs, the ants did not avoid them, but actually ...
