Stacking faults are seen to be abundant in epitaxial Co films grown on excess Ga covered GaN(0001)-”"1 x 1″” surface. Such stacking defects are effectively suppressed in Co films grown on less excess Ga covered GaN(0001)-(1 x 1) surfaces. The hetero-interface between Co and GaN(0001) is characterized by a disordered or

amorphous region, and diffusion of Ga and N from the substrate into Co is suggested. (C) 2011 American Institute of Physics. [doi:10.1063/1.3652761]“
“Two new flav-3-en-3-ol glycosides, kaempferiaosides BLZ945 C (3) and D (4), and two new acetophenone glycosides, kaempferiaosides E (5) and F (6), were isolated from the Thai natural medicine Krachai Dum, the rhizomes of Kaempferia parviflora Wall. ex Baker. Their structures were established mainly on the basis of 1D and 2D NMR spectral data.”
“Background

Testicular neoplasms

resembling ovarian serous tumors are rarely reported. We describe the first fine needle aspiration biopsy (FNAB) finding of this type of tumor.

Case

A 35-year-old man presented with an enlarged right testis. Based on clinical observation, we hypothesized that it was selleck kinase inhibitor a malignant tumour FNA cytology findings revealed numerous papillary clusters, glandular-like structures and many isolated round cells. Metastatic papillary adenocarcinoma was suspected based on FNAB cytology. A right radical orchiectomy was performed, and histologic tissue examination was used to diagnose the tumor as a benign papillary serous cystadenoma.

Conclusion

Papillary serous cystadenoma of the testis is a rare tumour. The cytologic findings of this tumor are confusing and difficult. P005091 to diagnose. Clusters of epithelial cells with

a high nuclear to cytoplasm ratio, are mistake for features of a malignant tumor (Acta Cytol 2009;53:467-470)”
“The only unequivocal radiological effect of the Chernobyl accident on human health is the increase in thyroid cancer in those exposed in childhood or early adolescence. In response to the scientific interest in studying the molecular biology of thyroid cancer after Chernobyl, the Chernobyl Tissue Bank was established. The project is supported by the governments of Ukraine and Russia, and financially supported (in total around US$3million) by the European Commission, the National Cancer Institute of the USA and the Sasakawa Memorial Health Foundation of Japan. The project began collecting a variety of biological samples from patients on 1 October 1988, and has supplied material to 21 research projects in Japan, the USA and Europe. The establishment of the Chernobyl Tissue Bank has facilitated co-operation between these research projects and the combination of clinical and research data provides a paradigm for cancer research in the molecular biological age.
