Pyranopterin Coordination Controls Molybdenum Electrochemistry in Escherichia coli Nitrate Reductase
DownloadFall 2015
Molybdenum is an essential trace element for most species on the earth. Molybdoenzymes (enzymes containing Molybdenum) play diverse roles in human health, global geochemical cycles, and bacterial metabolism. Interestingly, nitrate reductase (NarGHI) isolated from the common gut bacterium...

Fall 2017
Gram-negative bacteria are separated from the environment by a multilayered structure known as the envelope, which is comprised of the outer membrane, the inner membrane and the aqueous periplasmic space that lies between the two membranes. Biogenesis of the envelope is a complex process that...

Respiration, Acid/Base, Ammonia and Ionoregulatory Strategies in the Pacific hagfish (Eptatretus stoutii)
DownloadFall 2016
Hagfish feed on putrefied carrion, which poses several environmental challenges to the scavenger including hypoxia (Low PO2), hypercapnia (high PCO2) and high environmental ammonia (HEA). To any other organism, these conditions would be physiologically challenging; however, hagfish seem to have...

Respiratory, laryngeal, and articulatory adjustments to changes in vocal loudness in typically developing children and children with spastic-type cerebral palsy
DownloadSpring 2011
This study explored the physiological adjustments made by the speech mechanism when sustained maximum phonations and sentences differing in vocal loudness were produced by typically developing children and children with cerebral palsy (CP). Respiratory adjustments (lung volume initiation,...

The Roles of the Respiratory Oscillators: Effects of Optogenetics and Cholinergic Perturbations on the Respiratory Functions
DownloadSpring 2017
Previous data have revealed the important and fundamental role in respiratory control of two groups of brainstem neurons: the preBötzinger Complex (preBötC) and the retrotrapezoid / parafacial respiratory group (RTN/pFRG). The preBötC which functions as the inspiratory oscillator, essential for...
