Flowing leukocytes are captured via L-selectin interactions with carbohydrate ligands on vessel walls and subsets of other leukocytes. L-selectin is an unusual adhesive molecule—shear stress improves its adherance to ligands, wherea...

Almost no clause, however, of Lewis's analysis has withstood the barrage of counter examples over the years, and a glance at the big dictionary suggests ...

Our projects on waterbirds are ideal for combining data collection with a bit of photography — we observe our focal broods from floating, mobile blinds, in wetlands teeming with waterbirds. With a really good blind, it’s like being invisible — we oft...

We have developed a 12-item questionnaire for patients having a total knee replacement (TKR). We made a prospective study of 117 patients before operation and at follow-up six months later, asking them to complete the new questionnaire and the form SF36. Some also filled in the Stanford Health Assessment Questionnaire (HAQ). An orthopaedic surgeon completed the American Knee Society (AKS) clini...
