Effects Of Energy Drink Additives On Crayfish Metabolism, Katherine Paltz
Effects Of Energy Drink Additives On Crayfish Metabolism, Katherine Paltz
Williams Honors College, Honors Research Projects
The effects of caffeine and additives commonly found in energy drinks were tested on crayfish to record changes, if any, in their metabolism. Three experimental groups were studied: 1. Caffeine; 2. Caffeine + Glucuronolactone; 3.) Caffeine + Glucuronolactone + Taurine. Caffeine is a common stimulant used to improve mental awareness, headaches, memory, and athletic performance. Glucuronolactone is connected with cardiovascular issues and aggressive behavior. Taurine is said to improve mood and focus. The experiment was performed at two different caffeine levels: 600mg and 1200mg for an initial 1 hour of exposure and 10 hours after exposure used as a pseudo-baseline. …
Multidimensional Mass Spectrometry Of Chemonic™ Ccg-6 Nonionic Surfactant With Separation By Polarity And Shape, Charles Johnson

Chemonic™ CCG-6 surfactant is a water-soluble poly(ethylene glycol) (PEG) conjugated alkyl glyceride emollient. This surfactant exists as a complex mixture of a glycerol cores conjugated with poly(ethylene glycol) branches (PEGylation) that were partially esterified with caprylic (C8) and capric (C10) acids. These may be esterified on one, two, or all three arms of the glyceride. The architecture of the structures in this mixture was studied using multidimensional mass spectrometry (MS). Mass spectrometry was interfaced with ultra-performance liquid chromatography (UPLC) and ion mobility (IM) separation. The mixture was separated by reversed-phase LC, oligomers of the star-branched polymer were separated according to …

Glutaredoxin, an enzymatic protein, is an important component of cell viability and function. It catalyzes reactions involved in DNA synthesis and innate immunity [1,4]. Glutaredoxin is also essential in antibiotic resistance in pathogenic bacterial species. Pseudomonas aeruginosa in particular is responsible for infecting the lung tissue of its human hosts, resulting in the development of pneumonia and cystic fibrosis [3]. Because glutaredoxin is pertinent in cell proliferation of eukaryotic and bacterial cells alike, medicinal fragments that take advantage of the subtle differences in protein structure of the orthologous proteins can be synthesized and enhanced to bind bacterial glutaredoxins, without inhibiting …
