Phylogeographic relationships were constructed for 72 Old and New World Crataegus species using combinations of four chloroplast and up to five nuclear regions. Maximum parsimony, maximum likelihood, and Bayesian results yield consistent relationships among major lineages. The close associations of the East Asian and western North American species point toward ancient trans-Beringian migrations...
A New Alkaloid named Sracosalgnenone [ (20S) -20(dimethylamino) -3β-tigoloyl-pregn-5, 16-diene-4-one] was isolated from sarcococca saligna and its structure was established on the basis of spectroscopic techniques includingH, C-NMR and inverse 2D-NMR techniques (DEPT, HMQC and HMBC) UV, MS etc.

The human polyomaviruses BK (BKPyV) and JC (JCPyV) are ubiquitous pathogens long associated with severe disease in immunocompromised individuals. BKPyV causes polyomavirus-associated nephropathy and hemorrhagic cystitis, whereas JCPyV is the causative agent of the fatal demyelinating disease progressive multifocal leukoencephalopathy. No effective therapies targeting these viruses are currently...
