Measuring pH is one of the most commonly used techniques in both the laboratory as well as the field due to its importance in a multitude of biochemical processes. Traditional methods of measuring pH may be highly developed in accuracy and precision but often involve disruption of the environment. Biological markers offer an alternative that allows for long-term pH monitoring. This innovative approach allows for vast applications such as in the manufacturing, food processing and research industries. Under moderate acidic conditions, the asr (acid shock RNA) gene is highly inducible and has been demonstrated to be crucial for growth at …
P03. Role Of Prefrontal Cortical Dopamine Transmission In Post-Traumatic Stress Disorder And Opiate Addiction Vulnerability, Jingjing Li
Western Research Forum
Background
PTSD and opiate addiction share strong co-morbidity and the inability to suppress obtrusive memory recall related to either stressful or rewarding experiences may be an underlying neuropsychological feature triggering PTSD and/or addiction. Our previous research has shown that dopamine (DA) transmission in the prefrontal cortex (PFC) strongly modulates emotional memory formation: activation of the DA D4 receptor (D4R) strongly potentiates the emotional salience of normally non-salient fear memories whereas DA D1 receptor (D1R) activation blocks the behavioural recall of fear memory. Thus, while intra-PFC D4 transmission strongly controls the acquisition of emotional memory, D1 transmission is selectively involved in …
P27. Acute Impact Of An Extremely Low Frequency Magnetic Stimulus On Human Neurophysiological Function - Magnetophosphene Perception, Cadence M. Baker
P27. Acute Impact Of An Extremely Low Frequency Magnetic Stimulus On Human Neurophysiological Function - Magnetophosphene Perception, Cadence M. Baker
Western Research Forum
Background: Magnetophosphenes are classified as colourless, flickering lights that are perceived with closed eyes in the dark, and upon exposure to a magnetic field (MF). Uncertainties exist involving the MF threshold for magnetophosphene perception.
Methods: Forty subjects will be enrolled in this experiment aiming to provide a frequency-response curve of magnetophosphene perception under MF exposure. Subjects will sit in a whole head MF exposure device wearing a 64-channel MRI-compatible EEG cap. Subjects will be exposed to a MF with a frequency of 5-300 Hz, in the form of an increasing flux density ramp (increasing magnetic field flux density from 0-100 …
Pulmonary Surfactant Fortified With Cath-2 As A Novel Therapy For Bacterial Pneumonia, Brandon J. Baer
Pulmonary Surfactant Fortified With Cath-2 As A Novel Therapy For Bacterial Pneumonia, Brandon J. Baer
Western Research Forum
Background: Bacterial pneumonia is a leading cause of death worldwide, with high mortality rates persisting even after antibiotic treatment. Current treatments for pneumonia involve administration of antibiotics, however after the bacteria are killed they release toxic substances that induce inflammation and lung dysfunction. Host defense peptides represent a potential solution to this problem through their ability to down regulate inflammation. However, effective delivery to the lung is difficult because of the complex branching structure of the airways. My study addresses this delivery problem by using exogenous surfactant, a pulmonary delivery vehicle capable of improving spreading of these peptides throughout the …

Background: Acute respiratory distress syndrome (ARDS) is defined as severe lung dysfunction that occurs after an insult to the lung such as an infection. The lung dysfunction in ARDS is due to alterations to surfactant, a lipid-protein mixture coats the inside of the lung and …
