Xanthanolides in L.: Structures, Synthesis and Bioactivity.

Xanthanolides were particularly characteristic of the genus , which exhibited broad biological effects and have drawn much attention in pharmacological application. The review surveyed the structures and bioactivities of the xanthanolides in the genus , and summarized the synthesis tactics of xanthanolides. The results indicated that over 30 naturally occurring xanthanolides have been isolated from the genus in monomeric, dimeric and trimeric forms.

Histiocytoid breast carcinoma, neither lobular nor ductal? A case report and literature review.

Histiocytoid breast carcinoma (HBC) is a rare type of breast cancer with controversial histogenesis, which is characterized by abundant foamy cytoplasm, fuzzy cell boundary, linear or annular infiltration, eccentric large irregular nuclei or prominent nucleoli and low mitotic activity. HBC has been considered to be a variant of lobular carcinoma, a variant of apocrine ductal carcinoma, and an apocrine variant of lobular carcinoma and to resemble lipid-rich carcinoma. We presented a case of 75-year-old woman with a 5-cm mass in the left breast.
