Those residents who do not react to two-step PPD testing are immunologically naive to TB and susceptible to primary tuberculosis infection. Some may be anergic. THE BOOSTER PHENOMENON In persons who had initial infection and skin testing many years in the past, skin test reactivity may wane. ...
aβ-glucosidase localized to the chloroplast, was discovered to specifically hydrolyze PPD ginsenosides in PNLs by selectively removing one outer glucose residue at the C-3 site. Due to spatial separation betweenβ-glucosidase and its substrates in cells, ginsenoside...

There are two key issues which need to be raised when dealing with the concept of homework. Firstly, there is the question of home. Often homework is not done at home at all, but at a friend's house, on the street, on the bus on the way to class or sitting o...
In this pathway, α-D-glucuronic acid (GlcUA) is converted into 2-keto-3-deoxygluconate (KDG) by a three-step process. The subsequent phosphorylation of KDG yields 2-keto-3-deoxy-6-phosphogluconate (KDPG), which is finally cleaved to produce glyceraldehyde 3-phosphate (G3P) and pyruvate....
iterative process to build and establish a dendritic arbor. Fig. 7 A two-step model for PVD dendrite development. 1) Guidance receptor complexes first recruit and activate the WRC, which in turn produces a branched actin network resulting in the formation of swellings. 2) The WRC (likely ...
Two-step ppd skin testing in patients infected with the human immunodeficiency virus (HIV)The recommendations suggested in this minireview must be regarded as tentative pending the performance of comparative studies. Until such studies are performed, however, the approaches suggested in this minireview...

Taken together, we propose a two-step evolution model for fruit size enlargement in apple to characterize its unique evolution process (Fig.4c). Unlike modern maize and tomato whose domestication process started with ancestral species bearing very small seeds or fruits4,5, apple domestication was ...
