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.
A DNA nucleotide is one of two kinds of bases... a pyrimidine or a purine. The purine is a heterocyclic (two-ring) molecule with a 5 member and 6 member ring each containing 2 â¦ Nitrogens.Purines are just a single ring with 2 Nitrogens.Each base is paired with a sugar (ribose) less one oxygen (hence the prefix de-oxyribose).here are four nucleotides that make up DNA: Adenine, Thymine, Guanine and Cytosine. There are billions of them that make up one strand of DNA. Adenine always pairs with Thymi â¦ ne and Guanine always pairs with Cytosine.
