Do Artificial Riffles Enhance Nutrient Retention In Restored Streams?, Adam Thomas Hughes

Masters Theses

Kickapoo Creek, a tributary of the Embarrass River in Central Illinois, has undergone a stream restoration that included the construction of two artificial riffles. These structures were designed to slow flood waters, increase channel and substrate stability, and increase habitat heterogeneity in a stream impacted by erosion and sediment deposition. They may also provide stable substrates that affect the algal community, leading to shifts in algal community composition, increases in the biomass of primary producers, and subsequent increases in nutrient retention. I explored the effects of the restoration on instream nutrient retention by measuring and comparing phosphate uptake lengths, velocities, …

The Effects Of 1, 3, & 7 Trisubstituted And 8-Cyclopentyl Alkylxanthines On Respiration In Newborn Rats, Nathan Creel Davidson

Masters Theses

Methylxanthines have been shown to be promising respiratory stimulants in newborns suffering from recurrent apnea. The respiratory stimulant effects of methylxanthines are most likely due to their antagonism of adenosine receptors. These drugs have been shown to stimulate respiration in newborn rats in doses in excess of 10 mg/kg body weight. Structure-activity studies have shown that methylxanthines not only differ in the antagonism of A₁ and A₂ adenosine receptors but also, as a consequence of their different chemical structures, differ in potency as respiratory stimulants. To assess this, two potent A₁ adenosine receptor antagonists, 8-cyclopentyl-1,3-dipropylxanthine (DPCPX) and …
