As part of an effort to improve efficiency of space-flight medical support at Kennedy Space Center, a training video was created to replace a series of lectures given before a launch or landing of the Space Shuttle. The video was designed to familiarize volunteer physicians from around the country with the specific emergency response protocols for a Space Shuttle launch or landing emergency at Kennedy Space Center. The methods used were consistent with standard film making techniques as outlined in several film making texts. The Production was divided into three phases; A pre-production phase wherein the research, screenwriting and production …

This experiment analyzes synaptic differences in the central auditory pathway between normal hearing and congenitally deaf (dn/dn) mice, and provides valuable insight into central changes that correspond with human congenital deafness. Specifically, this experiment analyzes developmental expression of the Calcium (Ca2+)-binding proteins Calretinin (CR), Calbindin D-28k (CB) and Parvalbumin (PV) in large excitatory synapses in the anteroventral cochlear nucleus (AVCN) and the medial nucleus of the trapezoid body (MNTB) of normal and dn/dn mice. Immunofluorescence imaging with primary antibodies detecting CR, CB or PV was used to analyze the expression of each at 9 days, 13 days, 20 days, 30 …
Clinical Presentation Of Acute Coronary Syndrome: Does Age Make A Difference? Implications For Emergency Nursing, Iesiah M. Harris
Clinical Presentation Of Acute Coronary Syndrome: Does Age Make A Difference? Implications For Emergency Nursing, Iesiah M. Harris

Accurately recognizing symptoms of Acute Coronary Syndrome (ACS) presents a challenge to Emergency Department (ED) nurses and physicians. Due to the variety of clinical presentations in patients, ACS is frequently missed diagnosed. Studies demonstrate that many patients present with atypical symptoms and presentation varies based on gender. There is, however, a paucity of studies on the presentation of ACS in the elderly. With the older American population growing at exponential rates, it is imperative that studies are conducted to better comprehend ACS clinical presentation in the elderly. By 2020, it is anticipated, that 20% of the population will be 65 …
The Relationship Between Lactic Acid, Reactive Oxygen Species And The Hypoxia-Induced Acidification Seen In Chemosensitive Neurons Of The Nucleus Tractus Solitarius (Nts), Trevor Downing
Browse all Theses and Dissertations
The NTS is one of many sites of chemoreception meaning that it responds to changes in CO2 and pH. NTS neurons also acidify approximately 0.13 pH units in response to hypoxia. Experiments involved brainstem slices exposed to a control hypoxic bout followed by hypoxia in conjunction with different drugs. The drugs included fluorocitrate, 4-hydroxycinnamate, oxygen-glucose deprivation and iodoacetate. Iodoacetate produced the strongest blunting of the hypoxia-induced acidification and decreased the response by ~53%. Results from the studies using the superoxide probe DHE showed an increase in the levels of ROS during the hypoxic exposure prior to reoxygenation. Two ROS scavengers …
