...rt protein pieces called peptides. The recent work finds that the acquired PBP2A serves to link peptides while the native PBP2 links sugars. This explains why it is possible for PBP2 to aid in resistance while still being inactivated by the antibiotic.

March of Dimes grantee finds first evidence of gene-smoking interaction WHITE PLAINS, N.Y., JAN. 9, 2002 Why do some women who smoke cigarettes during pregnancy have low birthweight babies while others do not?

The study finds high levels of inorganic nitrogen in the United States, long thought to be the natural mainstay of the ecosystem, are really the result of acid rain and agricultural fertilizers.
