Niche Partitioning And Utilization Of Different Nitrogen Sources By Marine Cyanobacteria Synechococcus, Angel Bui, Anne W. Thompson
Niche Partitioning And Utilization Of Different Nitrogen Sources By Marine Cyanobacteria Synechococcus, Angel Bui, Anne W. Thompson
McNair Symposium
The Cyanobacterium Synechococcus plays a major role in the ocean’s biochemical processes and is responsible for a significant amount of primary production, especially around coastal areas. Synechococcus has a wide geographical distribution that includes both polar and high-nutrient waters. Within the genus, there are defined subpopulations that are ecologically distinct that allow them to niche partition the dynamic oceans. To further explore niche partitioning of Synechococcus, this project combines a bioinformatic and culture-based approach. I examined data along the North Pacific Subtropical Front (NSPF) to analyze the community structure. This analysis demonstrated that a particular ecotype identified as clade II …

Cd40l And Tnf-Alpha Levels After Traumatic Injury, Queen Revollido, Martin Schreiber
McNair Symposium
The biomarkers CD40 ligand and TNF-alpha are proteins that exhibit proinflammatory and prothrombotic effects. A small clinical study has shown that soluble CD40 ligand may have a role in early coagulopathy and inflammatory complications in severely injured patients. It is known that a CD40 ligand increases the production of cytokines such as TNF-alpha, thus, the current study aims to investigate the kinetics of these biomarkers and the extent of upregulation after traumatic injury. Frozen samples collected from baseline, 8, 24, and 48 hours after admission will be used. CD40 ligand and TNF-alpha levels will be quantified using Luminex that will …
