The three-dimensional structure of channels and bacula cavities in the wall of hazel pollen grains was investigated by automated electron tomography in order to explore their role in the release of allergen proteins from the pollen grains. 3D reconstructions of 100-150 nm thick resin-embedded
70 consecutive patients undergoing heart surgery for mitral valve disease were studied: at operation 6 of them exhibited left atrial thrombi (LAT). Dimension of the thrombi varied from a hazel-nut to an orange, 4 of them adhered to the posterior atrial wall, 2 of these obliterated the left atrial

Turkey is a rich source of European hazelnut (Corylus avellana) germplasm with nearly 400 accessions in the national collection. This genetic material encompasses cultivars, landraces and wild genotypes which were characterized for 12 nut and 13 kernel traits over 2 years in the 1990s. Analysis of
