Assessment Of The Extraction And Quantification Of Pfbs From Sprague Dawley Rat Adipose Tissues, Joshua O. Osaghae

Honors College Theses

Per- and polyfluoroalkyl substances (PFAS) are a group of complex synthetic chemicals that have applications ranging from automotives to consumer products. PFAS have been found to bioaccumulate in the ecosystem as their carbon-fluorine bonds are among the strongest bonds in organic chemistry. Perfluorobutanesulfonic acid (PFBS) compounds are used as surfactants in water- and stain-repellent coatings for fabrics and carpets, cleaning agents, and paints. The persistence of PFAS has led to their accumulation in sources of groundwater, making them ubiquitous drinking water contaminants of concern with evidence linking PFAS exposure to adverse health effects, including reduced kidney function, thyroid disruption, and …

Fungal Activity In Fusarium Keratoplasticum Isolates With And Without Endohyphal Bacteria On Various Carbon Sources, Maya Brown

Ca2+ Binding Shifts Dimeric Dual Oxidase's Truncated Ef-Hand Domain To Monomer, Chin-Chuan Wei, Amena Razzak, Hadis Ghasmi

SIUE Faculty Research, Scholarship, and Creative Activity

Hydrogen peroxide, produced by Dual Oxidase (Duox), is essential for thyroid hormone synthesis. Duox activation involves Ca2+ binding to its EF-hand Domain (EFD), which contains two EF-hands (EFs). In this study, we characterized a truncated EFD using spectrometry, calorimetry, electrophoretic mobility, and gel filtration to obtain its Ca2+ binding thermodynamic and kinetics, as well as to assess the associated conformational changes. Our results revealed that its 2nd EF-hand (EF2) exhibits a strong exothermic Ca2+ binding (Ka = 107 M−1) while EF1 shows a weaker binding (Ka = 105 M−1), resulting in the burial of its negatively charged residues. The Ca2+ …

An Updated Practical Guide To Taking And Defending Depositions, Gary Gildin

Faculty Scholarly Works

The deposition offers a singular opportunity to handcuff the deponent to an irreversible script. Consequently, both the attorney taking the deposition and defending counsel must prepare for and conduct the deposition with equal if not greater care than the trial.

Traditionally, lawyers have used the deposition to discover facts relating to the legal elements and the credibility, perception, and recollection of the witness. However, recent breakthroughs in neuroscience as to how the brain makes decisions have revealed a different genre of evidence that will drive how the trier of fact will decide the case. Today an attorney taking a deposition …
