13. Construction and purification of site-specifically modified DNA templates for transcription assays
Chemical and physical agents can alter the structure of DNA by modifying the bases and the phosphate–sugar backbone, consequently compromising both replication and transcription. During transcription elongation, RNA polymerase complexes can stall at a damaged site in DNA and mark the lesion for repair by a subset of proteins that are utilized to execute nu

15. Damage to photosystem II in symbiotic dinoflagellates: A determinant of coral bleaching
Coral bleaching has been defined as a general phenomenon, whereby reef corals turn visibly pale because of the loss of their symbiotic dinoflagellates and/or algal pigments during periods of exposure to elevated seawater temperatures. During the summer of 1997, seawater temperatures in the Florida Keys remained at or above 30°C for more than 6 weeks, and ex

16. Characterization of growth hormone enhanced donor site healing in patients with large cutaneous burns.
BACKGROUND: Human growth hormone is an anabolic agent that attenuates injury-induced catabolism and stimulates protein synthesis. Recombinant human growth hormone (rhGH) administered therapeutically to patients with massive burns has been shown to increase the rate of skin graft donor site healing. It has been postulated that growth hormone affects wound hea
