The effects of 2,3,7,8-tetrachlorodibenzo-p-dioxin on T cell activation

Creator:: Shepherd, David M.
Abstract:: The immune system has been identified as a very sensitive target for the toxic effects of 2,3,7,S-tetrachlorodibenzo-p-dioxin (TCDD). Exposure to TCDD has been shown to disrupt the generation of both cell-mediated and humoral T cell-dependent immunity in laboratory animals; however, the mechanism remains unknown. In this dissertation, the hypothesis is...

The influence of aryl hydrocarbon receptor activation on T cell fate

Creator:: Funatake, Castle J.
Abstract:: 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) and related compounds are well-recognized for their immunosuppressive activity, which is mediated through an intracellular receptor and transcription factor, aryl hydrocarbon receptor (AhR). Laboratory animals exposed to TCDD are less resistant to infection and have severely impaired humoral and cell-mediated immune responses. This dissertation addressed the hypothesis that...

The role of costimulation and adjuvants in the development of T cell effector and memory responses

Creator:: Maxwell, Joseph R.
Abstract:: T cells are one of the key cells in the immune system. Although they are not the first line of defense against a pathogen, their functions can greatly enhance the phagocytosis and destruction of pathogens as well as the development of antibody responses. Furthermore, even when responding T cells have...

A study of symmetric matrices and quadratic forms over fields of characteristic two

Creator:: Furcha, John Arthur
Abstract:: This thesis has four main results. First we find a reduction form for symmetric matrices over fields of characteristic two. This result parallels the diagonalization theorem for symmetric matrices over fields of characteristic not two. Secondly we reduce our reduction form to a canonical form in perfect fields of characteristic...

Lipid/bitumen maturation by hydrothermal activity in sediments of Middle Valley, leg 139

Creator:: Simoneit, Bernd R. T.
Abstract:: The accelerated diagenesis, maturation, and catagenesis of organic matter to hydrothermal petroleum was studied in sediments from Ocean Drilling Program Leg 139 in Middle Valley, northern Juan de Fuca Ridge. Sediments at Sites 855 and 856 have experienced high heat flow resulting in accelerated diagenesis of the immature organic matter...

Testing for location after transformation to normality

Creator:: Halawa, Adel Mahmoud
Abstract:: In the problem of testing the median using a random sample from a certain distribution, and if no other parametric family is suggested, the t-test is known to be the optimal procedure when this distribution is normal. If the sample appears to be non-normal, one has the choice either to...
