The role of molehills and grasses for filial nest founding in the wood ant Formica exsecta (Hymenoptera: Formicidae)
In polydomous populations of the wood ant Formica exsecta filial nest founding is common. This is relevant for colony dynamics, short-distance dispersal and colony survival. However, little is knownExpand

Monitoring thiopurine methyltransferase (TPMT) activity in inflammatory bowel disease: is it worth it?
Introduction Azathioprine and 6-mercaptopurine are immunosuppressants used to treat inflammatory bowel disease (IBD). Marrow toxicity occurs in 3% of patients receiving these drugs. SomeExpand
Gastrointestinal responses to a panel of lectins in rats maintained on total parenteral nutrition.
Total parenteral nutrition (TPN) causes atrophy of gastrointestinal epithelia, so we asked whether lectins that stimulate epithelial proliferation can reverse this effect of TPN. Two lectinsExpand
