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.
Guanine is the other purine nucleotide in DNA. Guanine pairs with cytosine in the DNA structure. Guanine differs from adenine in that it is made up of oxygen in addition to carbon, hydrogen and nitrogen. Like adenine, guanine consists of two rings, one with five members and one with six. Guanine also allows for synthesis of glucose when it is the nitrogenous base for guanosine triphosphate.
