Mechanical coupling through the skin affects whisker movements and tactile information encoding.

Rats use their whiskers to extract sensory information from their environment. While exploring, they analyze peripheral stimuli distributed over several whiskers. Previous studies have reported cross-whisker integration of information at several levels of the neuronal pathways from whisker follicles to the somatosensory cortex.

Effects of heparin, dermatan sulfate and of their association on the inhibition of venous thrombosis growth in the rabbit.

This study compares the ability of unfractionated heparin, of dermatan sulfate, and of their simultaneous administration delivered as continuous intravenous infusion or as a single bolus injection to inhibit the growth of a standardized venous thrombosis in the rabbit. When delivered as continuous intravenous infusion for 4 h, heparin and dermatan sulfate inhibited thrombus growth in a dose dependent manner. The maximum antithrombotic effect of heparin was achieved at the dose of 0.
