... II) and dogs with disturbances of supraventricular conduction (group III). The tests were carried out in 53 healthy dogs, 23 dogs with chronic valvular disease and 12 dogs with disturbances of supraventricular ... The P-wave dispersion is a constant index in healthy dogs, that is why it can be used for evaluating P wave change in dogs w...

... could not obtain any information about the ice-binding ability of the glycan part of AnpAFP. Direct involvement of gly- can in ice binding has been suggested only for fish AFGP consisting of an -Ala-Thr-Ala- ... species of fish type II AFP [28]. There is no involvement of glycans in ice binding of these proteins because no significant change in the ice- binding activity was d...
