Determination Of Pancreatic And Salivary Amylase By Enzyme Immunoassay And Their Prevalence In Hyperamylasemic Patients, Sabdra Borgens Ward
Determination Of Pancreatic And Salivary Amylase By Enzyme Immunoassay And Their Prevalence In Hyperamylasemic Patients, Sabdra Borgens Ward
Theses and Dissertations in Biomedical Sciences
Currently, amylase determinations are nonspecific for the organ source and are based entirely on the enzymatic properties of amylase to produce a measurable product or byproduct. The determination of pancreatic amylase is important in the diagnosis of acute pancreatitis. Most commercially available tests for amylase employ the measurement of the change in NADH absorbance at 280 nm or of the p-nitrophenol released from a maltotetrose substrate. These are nonspecific measurements of pancreatic amylase and often necessitate other tests to be run such as a serum lipase.
The two predominant isoenzymes of amylase are pancreatic (p-amylase) and salivary (s-amylase); the most …
Investigation Of Selenium Status In Hypo-, Hyper- And Euthyroid Children, Ping Sun
Investigation Of Selenium Status In Hypo-, Hyper- And Euthyroid Children, Ping Sun
Chemistry & Biochemistry Theses & Dissertations
Recently, it has been reported that human type I iodothyronine deiodinase, an enzyme important in the conversion of T4 to T3 , is a selenoenzyme. Several studies have reported alterations in plasma selenium level in hypo- and hyperthyroid patients.
Using polarized Zeeman-effect atomic absorption spectroscopy, we measured selenium, zinc, copper and manganese concentrations in the plasma and/or red blood cells in children with or without thyroid disease being seen at the outpatient clinic at Children's Hospital of the King's Daughters. Children with thyroid disease were subdivided into untreated, treated and nonresponsive groups. Data were analyzed using Student's t-test …
An Analysis Of Mitochondrial Dna In Rett Syndrome And Other Neurodegenerative Disorders, Catherine Erickson Burgess
An Analysis Of Mitochondrial Dna In Rett Syndrome And Other Neurodegenerative Disorders, Catherine Erickson Burgess
Theses and Dissertations in Biomedical Sciences
Mitochondrial dysfunction resulting from mutations on mitochondrial DNA (mtDNA) is being recognized in a growing spectrum of diseases. These diseases, resulting from single base mutations, large deletions, or insertions, have been largely neuromuscular in origin. However, as an understanding of the effects of mtDNA mutations progresses, attention is now focusing on neurodegenerative diseases. Rett Syndrome (RS), a progressive neurodegenerative disease with predominantly female cases, demonstrates morphologic mitochondrial changes, mitochondrial enzyme deficiencies and maternal inheritance (characteristic of mtDNA diseases). No investigation of mtDNA involvement has been previously conducted and, to date, no biological marker exists for this disorder.
Our preliminary studies …
