1,7-Dihydroxy-3,4-dimethoxyxanthone (XAN) is a bioactive compound isolated from Securidaca inappendiculata Hassk. and validated with antiproliferative activities on a panel of cancer cell lines. This study was designed to investigate its growth inhibitory effects on multidrug resistance (MDR) non-small cell lung carcinoma (NSCLC) cell line A549/Taxol and explore the possible linkage between mod...

Coronary anomalies are relatively common but rarely associated with syncope, myocardial ischemia, and sudden cardiac death. An anomalous right coronery artery from the left sinus of valsalva is now recognized as an important causative factor in sudden death and myocardial infarction and syncope.This case report presents an anomalous right coronary artery (RCA) originating from the left sinus of...

Paleosecuridaca curtisii Pigg, DeVore, and Wojciechowski gen. et sp. nov. (Polygalaceae) is described for anatomically preserved, nonschizocarpic, asymmetric samaras from the Late Paleocene (Tiffanian 3) Almont and Beicegel Creek floras of North Dakota. Paleosecuridaca is quite similar to the extant genus Securidaca L. (Polygalaceae) but has several distinctive features that warrant the establi...

In this research, hexane and acetone extracts of Bauhinia rufences, Securidaca longepedunculata and Ziziphus abyssinica were investigated for antibacterial activity. The phytochemical screening of the plants leaves extracts was conducted using standard methods of analyses. The effects of the two solvent extracts on the bacterial species (Escherichia coli, Psuedomonas aeruginosa, Salmonella typh...
