Ageratum salvanaturae (Eupatorieae, Compositae), a new species from the National Park El Imposible, Ahuachapán, El Salvador
Abstract Kilian, N. & Smalla, B.: Ageratum salvanaturae (Eupatorieae, Compositae), a new species from the National Park El Imposible, Ahuachapan, El Salvador. — Willdenowia 31: 137–140. 2001. — ISSN 0511-9618. Ageratum salvanaturae, an eglandular, epappose and epaleate herb with its capitula regularly aggregated in compact, globular synflorescences, is described as a species new to science and illustrated. It is known only from five collections made at medium altitudes in the El Imposible National Park in NW El Salvador near the border with Guatemala. Its relationship is uncertain.
Standard therapy options are limited for patients with refractory chronic lymphocytic leukemia, with or without lymphadenopathy, and the results are generally poor. Ofatumumab (Arzerra), a novel human CD20 monoclonal antibody, could be the answer for improving outcomes in this patient population. Lead investigator William G. Wierda, MD, PhD, will share the final analysis of the results from this international study at ASH 2010.
