A 12 page overview of canine oral spirochetes, concentrating on Treponema denticola, Treponemapectinovorum, and Treponema maltophilum. Notes that although oral microflora cannot be held solely responsible for the presence or absence of periodontal disease and associated conditions, thesemicroflora do manifest differently in healthy verses diseased tissue. This observation is true both in the species which are present and in what concentrations they are present. Suggests laboratory methodologyfor qualifying and quantifying their presence, as well as linking thatpresence to periodontal disease. Bibliography lists 15 sources.

Circadian Rhythms: Ultimately in Control
[ send me this essay ]
A 5 page paper discussing whether students who consciously choose early schedules for themselves might perform better than those waiting until much later in the day to begin their daily studies. The paper uses studies in the emerging field of chronobiology, which is devoted to the study of the circadian rhythms resident in all living organisms. There is not yet any empirical evidence linking academic performance to the circadian cycle, but there is ample evidence that even long-term shift workers adjust only psychologically, but not physiologically. As the field of chronobiology matures, it is reasonable to assume that the same link will be found between circadian rhythms and academic performance. Bibliography lists 6 sources.

Debating the Origins of Eukaryotic Flagella
[ send me this essay ]
This 4 page paper provides an overview of the current literature on this topic. Current scientific research still shows a significant debate over the origins of eukaryotic flagella. Lynn Margulis first proposed endosymbiont theory in an effort to settle the debate on the origins of structures, including eukaryotic flagella. Her theory and the use of 16s rRNA analysis provided a basis for relating the origins of both mitochondria and chloroplasts, yet does not completely resolve arguments over the origins of the eukaryotic flagella.
