Betulinic acid had actiity against HI at the micromolar leel," says Graham Allaway, Panacos's chief operating officer."This deriatie had actiity at the nanomolar leel.

PA-457 was not just another Taxol, the anticancer drug that required the controersial felling of rare yew trees until a semisynthetic substitute was found. Panacos did not need a steady source of Taiwanese herbs. Betulinic acid could be extracted from ubiquitous plane and birch trees, and a subsequent processing step yielded the desired molecule.

PA-457不像抗癌药物太平洋紫杉醇：在太平洋紫杉醇的合成代替品出现前，砍伐罕见的太平洋紫杉一直引发争议；Panacos并不需要有稳定供应的台湾药草，桦木酸能从普遍存在的悬铃树和桦树中提炼，并且只要一个后续处理步骤，就可以制造出所需的分子。

Nature sent him into the world strong and lusty, in a thriving condition, wearing his own hair on his head, the proper branches of this reasoning vegetable, till the axe of intemperance has lopped off his green boughs, and left him a withered trunk, he then flies to art, and puts on a periwig, valuing himself upon an unnatural bundle of hairs, all covered with powder, that never grew on his head; but now should this our broomstick pretend to enter the scene, proud of those birchen spoils it never bore, and all covered with dust, through the sweeping of the finest lady's chamber, we should be apt to ridicule and despise its vanity.

Based on the established database for poplar and birch, the developed color measurement-matching system is used to carry out imitation of precious wood species such as Dalbergia fusca Pierre, Dalbergin bariensis Pierre and Juglans.

利用建立的杨木和桦木基础数据库，进行黑酸枝、红酸枝和黑胡桃等珍贵树材仿真，分别修正0~2次后即能达到要求，所模仿的珍贵木材材色与天然木材材色相近，着色均匀，色差小。

The latter clade could be further divided into two strongly supported subclades:(Juglandaceae-Rhoipteleaceae)-Myricaceae, and (Betulaceae-Ticodendraceae)-Casuarinaceae.4 Six sequences combined analysesPhylogenetic reconstructions were performed under a number of scenarios for each of five combined data sets to elucidate the stability of the phylogeny trees.

桦木科和木麻黄科聚在一起，胡桃科和马尾树科为姐妹群再与杨梅科构成一支，这两个分支都得到很强的BS支持。核基因分析支持六个序列联合分析对核心高等金缕梅类各科间关系的分辨。

Atopy was defined as a positive skin-prick test to mites, cat, Alternaria, Cladosporium, grass, birch, Parietaria, olive, or ragweed.

特应性定义为对螨类、链格孢属、分子孢子菌属、草、桦木、墙草属、橄榄或豚草属皮肤划痕实验阳性。

Reseal packages because they're easy and convenient to use," says Warren Birch, Bemis Europe's General Sales Manager for the UK and Ireland."
