Conformational Changes And Flexibility In T-Cell Receptor Recognition Of Peptide–Mhc Complexes, Kathryn M. Armstrong, Kurt H. Piepenbrink, Brian M. Baker Jan 2008

Conformational Changes And Flexibility In T-Cell Receptor Recognition Of Peptide–Mhc Complexes, Kathryn M. Armstrong, Kurt H. Piepenbrink, Brian M. Baker

Food for Health: Publications

A necessary feature of the immune system, TCR (T-cell receptor) cross-reactivity has been implicated in numerous autoimmune pathologies and is an underlying cause of transplant rejection. Early studies of the interactions of αβ TCRs (T-cell receptors) with their peptide–MHC ligands suggested that conformational plasticity in the TCR CDR (complementarity determining region) loops is a dominant contributor to T-cell cross-reactivity. Since these initial studies, the database of TCRs whose structures have been solved both bound and free is now large enough to permit general conclusions to be drawn about the extent of TCR plasticity and the types and locations of motion …

The Nestin Progenitor Lineage Is The Compartment Of Origin For Pancreatic Intraepithelial Neoplasia, Catherine Carriere, Elliot S. Seeley, Tobias Goetze, Daniel S. Longnecker, Murray Korc Mar 2007

The Nestin Progenitor Lineage Is The Compartment Of Origin For Pancreatic Intraepithelial Neoplasia, Catherine Carriere, Elliot S. Seeley, Tobias Goetze, Daniel S. Longnecker, Murray Korc

Dartmouth Scholarship

To determine the cell compartment in which initial oncogenic mutations occur in pancreatic ductal adenocarcinoma (PDAC), we generated a mouse model in which endogenous expression of mutated Kras (Kras(G12D)) was initially directed to a population of pancreatic exocrine progenitors characterized by the expression of Nestin. Targeting of oncogenic Kras to such a restricted cell compartment was sufficient for the formation of pancreatic intraepithelial neoplasias (PanINs), putative precursors to PDAC. PanINs appeared with the same grade and frequency as observed when Kras(G12D) was targeted to the whole pancreas by a Pdx1-driven Cre recombinase strategy. Thus, the Nestin cell lineage is highly …

Abdominal Pain With Rigidity Secondary To The Anti-Emetic Drug Metoclopramide, Nadeem Ullah Khan, Junaid A. Razzak May 2006

Abdominal Pain With Rigidity Secondary To The Anti-Emetic Drug Metoclopramide, Nadeem Ullah Khan, Junaid A. Razzak

Department of Emergency Medicine

We report a case of abdominal pain with rigidity, mimicking an acute abdomen, caused by metoclopramide, a common anti-emetic drug. Extrapyramidal symptoms are commonly reported side-effects of this medication. They generally include involuntary movements of limbs, torticollis, oculogyric crisis, rhythmic protrusion of tongue, trismus, or dystonic reactions resembling tetanus, etc. Abdominal rigidity due to this medication, resembling an acute abdomen, has not been reported previously. This case report illustrates the importance of considering medication side-effects when evaluating a patient with abdominal pain and rigidity.

The Development Of Electrophysiological Techniques Allowing "In Situ" Measurement Of Electrical Changes Within Smooth Muscle Cells Of Mesenteric Micro-Vessels, William J. Willems May 1970

The Development Of Electrophysiological Techniques Allowing "In Situ" Measurement Of Electrical Changes Within Smooth Muscle Cells Of Mesenteric Micro-Vessels, William J. Willems

Master's Essays (1922 - )

The primary objective or this study is essentially to acquire further knowledge of the factors involved in the nervous and humoral control of vascular smooth muscle tone. The relative importance of the nervous and endogenous vasotropic humoral control or vasomotor tone under normal conditions as well as under conditions or hypotension can be evaluated, at least in part, by observing the electrical activity occurring in single vascular smooth muscle cells of the mesenteric microcirculation. This thesis describes: 1) the development of electrophysiological methods for the measurement of such activity in ''in situ" micro-vessels with circulation and innervation intact, and 2) …
