Kathy and Susie, members of the faculty, and staff of the School of Natural Resource Sciences, ladies and gentlemen. There are some things in this world that, try as we may, just cannot be adequately accomplished. One of those things, for me at least, is to express adequately what I feel about the passing of Dr. Edward (Ted) Elliot. Ted came to this University of Nebraska a few months before I arrived, and it was my distinct honor to count him among my friends at this great University. Ted was a man of exceptional scientific standing and wisdom, and his loss leaves a void in all of our lives that will not be readily filled.

Few Nebraskans are as devoted to the University of Nebraska as Mark Gustafson. Driven by his belief that a strong university is key to a strong Nebraska economy, Mark is an advocate for the university in the local, state, and national arenas. He is a Nebraska delegate to the Council for Agricultural, Research, Extension, and Teaching, a national advocacy organization for higher education. Since 1991, he's been a member of Agriculture Builders of Nebraska, Inc., which supports UNL's Institute of Agriculture and Natural Resources, as well as the entire University, and has served three terms as president. He has served on the advisory councils for the UNL chancellor and the NU president and served on UNL's Future Nebraska Taskforce. He holds baccalaureate and master's degrees from UNL and a Ph.D. from the University of California-Berkeley. When he's not volunteering his time, Mark operates the family farm near Mead. He and his wife, Dianne, are the parents of two children - Christopher, a UNL alumnus, and Anneke, a UNL junior.

BACKGROUND.: Urine is a potentially rich source of biomarkers for monitoring kidney dysfunction. In this study, we have investigated the potential of soluble human leukocyte antigen (sHLA)-DR in the urine for noninvasive monitoring of renal transplant patients. METHODS.: Urinary soluble HLA-DR levels were measured by sandwich enzyme-linked immunosorbent assay in 103 patients with renal diseases or after renal transplantation. sHLA-DR in urine was characterized by Western blotting and mass spectrometry. RESULTS.: Acute graft rejection was associated with a significantly elevated level of urinary sHLA-DR (P<0.0001), compared with recipients with stable graft function or healthy individuals. A receiver operating characteristic curve analysis showed the area under the curve to be 0.88 (P<0.001). At a selected threshold, the sensitivity was 80% and specificity was 98% for detection of acute renal transplant rejection. sHLA-DR was not exosomally associated and was of lower molecular weight compared with the HLA-DR expressed as heterodimer on the plasma membrane of antigen-presenting cells. CONCLUSIONS.: sHLA-DR excreted into urine is a promising indicator of renal transplant rejection.

Antigenic peptide loading of major histocompatibility complex class II molecules is enhanced by lysosomal pH and catalyzed by the HLA-DM molecule. The physical mechanism behind the catalytic activity of DM was investigated by using time-resolved fluorescence anisotropy (TRFA) and fluorescence binding studies with the dye 8-anilino-1-naphthalenesulfonic acid (ANS). We demonstrate that the conformations of both HLA-DM and HLA-DR3, irrespective of the composition of bound peptide, are pH sensitive. Both complexes reversibly expose more nonpolar regions upon protonation. Interaction of DM with DR shields these hydrophobic domains from the aqueous environment, leading to stabilization of the DM and DR conformations. At lysosomal pH, the uncovering of additional hydrophobic patches leads to a more extensive DM–DR association. We propose that DM catalyzes class II peptide loading by stabilizing the low-pH conformation of DR, favoring peptide exchange. The DM–DR association involves a larger hydrophobic surface area with DR/class II-associated invariant chain peptides (CLIP) than with stable DR/peptide complexes, explaining the preferred association of DM with the former. The data support a release mechanism of DM from the DM–DR complex through reduction of the interactive surface, upon binding of class II molecules with antigenic peptide or upon neutralization of the DM–DR complex at the cell surface.

A pencilled note in the hand of John Langdon Sibley reads: "Probably the handwriting of Dr. Lardner." Sibley based his attribution on a letter from Nathaniel Lardner to Edward Wigglesworth, also written July 12, 1764, in the Houghton Library's autograph file during the nineteenth century. Verso of letter contains list, in another hand, of books donated to Harvard by Joseph Jennings.

Paper-covered notebook containing handwritten poems and verse by Harvard graduate John Allen. Some of the poems refer to Allen’s illnesses in October 1772. The notebook also contains a short list titled “The Gentleman that I wrote diplomas for," with a list of sixteen individuals who received degrees from Harvard. The inside cover includes the inscription: “John Allen – November 4, 1772. Poetic Composition.” “Dr. T. C. Gilman” is stamped on cover.

One letter briefly describing Russell’s studies at the home of Rev. Dr. McClintock in Greenland, N.H., where he was staying during a nine-month suspension from Harvard for theft of college property. Tudor, who was also found to be involved, was suspended for six months. Russell also inquires about fellow classmates, some of whom participated in the theft.

John Hubbard Church wrote these twelve letters to his friend and classmate William Jenks between 1795 and 1798. Church wrote the letters from Boston, Rutland, Cambridge, and Chatham in Massachusetts and from Somers, Connecticut; they were sent to Jenks in Cambridge and Boston, where for a time he worked as an usher in Mr. Vinall's school and Mr. Webb's school. Church's letters touch on various subjects, ranging from his increased interest in theology and his theological studies under Charles Backus to his seasickness during a sailing voyage to Cape Cod. Church also informs Jenks of what he is reading, including works by John Locke, P. Brydone, James Beattie, John Gillies, Plutarch, and Alexander Pope. He describes his work teaching that children of the Sears family in Chatham, Massachusetts, where he appears to have spent a significant amount of time between 1795 and 1797. Church's letters are at times very personal, and he often expresses great affection for Jenks and their friendship.

Volume kept by Dr. John Perkins (1698-1781) from 1724 to 1774 recording observations on various diseases and medical conditions illustrated with cases from Perkins's practice in Boston, Massachusetts. The cases ranged from epileptic fits, various fevers, and rheumatism to melancholy. His treament methods were standard for the era, mainly prescribing vomits, purges, and spirits, and bleeding patients. Also includes a section listing contradictory opinions among prominent medical writers such as Dutch physician Herman Boerhaave and English physician Thomas Sydenham. An index is located at the end of the volume. Perkins likely began compiling the book in 1765. It contains cases dating from 1724 to 1774.
