Heparin-induced thrombocytopenia: effect of heat inactivation of patient's serum on functional flow cytometric assay results.

Background: Heat inactivation of a patient's sample is not systematically performed in the diagnostics of heparin-induced thrombocytopenia (HIT). Some authors recommend that the patient's sample is heat-inactivated to avoid the effect of thrombin on platelet activation in a functional assay. Others do not find this additional step essential or even advise against it.

Immune related gene expression in worker honey bee (Apis mellifera carnica) pupae exposed to neonicotinoid thiamethoxam and Varroa mites (Varroa destructor).

Varroa destructor is one of the most common parasites of honey bee colonies and is considered as a possible co-factor for honey bee decline. At the same time, the use of pesticides in intensive agriculture is still the most effective method of pest control. There is limited information about the effects of pesticide exposure on parasitized honey bees.
