In one series, infection was the most common etiology of death in extremely low birth weight infants (56 of 111); congenital pneumonia accounted for 30 of these 56 infections [7]. Pneumonia caused by maternal enteric organisms frequently accompanies chorioamnionitis and/or funisitis in these congenital infections.
Diphenylguanidine is one of common accelerators for the vulcanization of rubber in combination with thiazoles and sulfenamides. Though it does not show better activity than thiuram and dithiocarbamates, it has better stability.
The four nitrogen bases found in DNA are adenine, cytosine, guanine, and thymine. Each of these bases are often abbreviated a single letter: A (adenine), C (cytosine), G (guanine), T (thymine). The bases come in two categories: thymine and cytosine are pyrimidines, while adenine and guanine are purines ().The pyrimidine structure is produced by a six-membered, two-nitrogen molecule; purine refers to a nine-membered, four-nitrogen molecule.he four nitrogen bases found in DNA are adenine, cytosine, guanine, and thymine.
