Development Of An Enzyme Linked Immunosorbent Assay Capable Of Detecting Antibodies Specific To The Cytomegalovirus, Rachel Bird
Development Of An Enzyme Linked Immunosorbent Assay Capable Of Detecting Antibodies Specific To The Cytomegalovirus, Rachel Bird
Undergraduate Honors Capstone Projects
The cytomegalovirus (CMV) is capable of causing serious illness and death in immunocompromised individuals. The objective of this research is to develop a method of detecting antibodies against CMV. This has lead to the development of an Enzyme linked Immunosorbent Assay (ELISA) that is capable of detecting CMV or anti-CMV antibodies. The process in the development of such an assay involves; 1) the purification of Hyperimmune Rabbit Serum containing anti-CMV antibodies, 2) determination of the appropriate concentrations necessary to provide a clear and concise response to the test, and 3) testing of monoclonal antibodies to determine their specificity towards the …
The Effects Of Thyroid Hormone On Myosin Heavy Chain A-7 Production In Xenopus Laevis Tail And Leg Muscles, Andrew R. Noble
The Effects Of Thyroid Hormone On Myosin Heavy Chain A-7 Production In Xenopus Laevis Tail And Leg Muscles, Andrew R. Noble
Honors Theses
The present research examines the expression of myosin heavy chain genes in muscle fibers in Xenopus laevis. Characteristically different muscle fibers are expressed before and after metamorphosis. The embryonic myosin proteins that are synthesized during the tadpole stages are replaced with adult myosin heavy chains at metamorphosis. At least one of the adult myosin genes, called A-7, is expressed only in the adult animals, not in tadpoles. The controlling factor or trigger for the expression of this adult gene still remains unknown. There are a number of possible explanations for the A-7 regulation at metamorphosis, including changes in particular hormone …

Scanning Electron Microscopic Study Of The Postnatal Development Of The Rabbit Cochlea, With An Emphasis On Innervation, Hirofumi Morita, Tomoyuki Hoshino, Kunihiro Mizuta, Satoshi Iwasaki
Scanning Microscopy
The development of nerve fiber arrangements of the organ of Corti was studied in rabbits 1, 3, 5, 7 and 12-days-old using thick sections from celloidin-embedded cochleas which were examined under a scanning electron microscope. The arrangements of nerve fibers varied with developmental age. The tunnel spiral bundle was thick and loosely collected in the immature cochlea. The outer spiral fibers were recognized even in the narrow space of Nuel in the one-day-old cochlea. As Nuel's space is extending, the fibers course along the medial side of Deiters' cells. The arrangement of the outer spiral fibers was irregular and sparse …

Biology - All Scholarship
The distal tip cell (DTC) regulates the proliferation or differentiation choice in the Cmorhabditis ekgans germline by an inductive mechanism. Cell signaling requires a putative receptor in the germline, encoded by the glp-1 gene, and a putative signal from the DTC, encoded by the lag-2 gene. Both glp-1 and lag-2 belong to multigene gene families whose members are essential for cell signaling during development of various tissues in insects and vertebrates as well as C. elegans. Relatively little is known about how these pathways regulate cell fate choice. To identify additional genes involved in the glp-1 signaling pathway, we carried …
Technical Improvements In Corrosion Casting Of Small Specimens: A Study On Mesonephric Tubules And Vessels Of Chicken Embryos, A. Carretero, H. Ditrich, M. Navarro, H. Splechtna, J. Ruberte
Technical Improvements In Corrosion Casting Of Small Specimens: A Study On Mesonephric Tubules And Vessels Of Chicken Embryos, A. Carretero, H. Ditrich, M. Navarro, H. Splechtna, J. Ruberte
Scanning Microscopy
The injection technique for corrosion casting of small, embryonic material can be improved by using a "chemical ligature" (cyanocrylate). With this simple method, leakage of the resin at the injection site is prevented and the mechanical stability of the cannula-vessel coupling is improved.
The blood vascular system of chicken embryos as small as Hamburger-Hamilton stage 24 (approximately 4.5 days of incubation) has successfully been injected using this procedure. Corrosion casts of the mesonephric tubular system have been made in a similar manner. Additionally, a simple way for secure transport of the fragile casts by immersion in 10% gelatin is suggested.
Intragenic Dominant Suppressors Of Glp-1, A Gene Essential For Cell-Signaling In Caenorhabditis Elegans, Support A Role For Cdcl O/Swz6/Ankyrin Motifs In Glp-1 Function, James L. Lissemore, Peter D. Currie, Christine M. Turk, Eleanor M. Maine

Biology - All Scholarship
The glp-1 gene product mediates cell-cell interactions required for cell fate specification during development in Caenorhabditis elegans. To identify genes that interact with glp-1, we screened for dominant suppressors of two temperature-sensitive glp-1 alleles and recovered 18 mutations that suppress both germline and embryonic glp-1 phenotypes. These dominant suppressors are tightly linked to glp-1 and do not bypass the requirement for a distal tip cell, which is thought to be the source of a signal that is received and transduced by the GLP-1 protein. Using single-strand conformation polymorphism (SSCP) analysis and DNA sequencing, we found that at least 17 suppressors …
Scanning Electron Microscope Observations Of Brine Shrimp Larvae From Space Shuttle Experiments, Lynnette Debell, Avelina Paulsen, Brian Spooner
Scanning Electron Microscope Observations Of Brine Shrimp Larvae From Space Shuttle Experiments, Lynnette Debell, Avelina Paulsen, Brian Spooner
Scanning Microscopy
Brine shrimp are encysted as gastrula stage embryos, and may remain dehydrated and encysted for years without compromising their viability. This aspect of brine shrimp biology is desirable for studying development of animals during space shuttle flight, as cysts placed aboard a spacecraft may be rehydrated at the convenience of an astronaut, guaranteeing that subsequent brine shrimp development occurs only on orbit and not on the pad during launch delays.
Brine shrimp cysts placed in 5 ml syringes were rehydrated with salt water and hatched during a 9 day space shuttle mission. Subsequent larvae developed to the 8th larval stage …
Morphological Correlates Of Mechanotransduction In Acousticolateral Hair Cells, J. O. Pickles, G. W. Rouse, M. Von Perger
Morphological Correlates Of Mechanotransduction In Acousticolateral Hair Cells, J. O. Pickles, G. W. Rouse, M. Von Perger
Scanning Microscopy
The development of ideas on mechanotransduction in acousticolateral hair cells is described, leading to the current idea that transduction depends on deflection of the bundle of stereocilia by a force parallel to the plane of the sensory epithelium. Electrophysiological experiments are summarised, suggesting that transduction depends on a shear between the different rows of stereocilia, and that the transducer channels are situated towards the tips of the stereocilia. Analysis of the ways that shear between the rows of stereocilia could be detected suggests that tip links are the structures which are most likely to transmit the stimulus-induced forces to the …
Cell Rearrangement And Directional Migration In Pronephric Duct Development, T. J. Poole
Cell Rearrangement And Directional Migration In Pronephric Duct Development, T. J. Poole
Scanning Microscopy
The morphology of the directed migration of the pronephric duct rudiment of three vertebrates, the salamander, chick and sturgeon, has been examined by scanning electron microscopy. Of particular interest in this paper are the morphology of the duct tip, the role of cell rearrangement, and the relation of duct extension to somite segmentation. The duct rudiments of all three species have motile cell processes (lamellipodia and filopodia) largely confined to their posterior tips. The salamander and sturgeon embryos extend their duct rudiments by extensive cell rearrangements. A short, wide rudiment is elongated to form a long, thin one. The chick …

Some Factors Involved In Growth And Sporulation Of Pilobolus Crystallinus Tode And Pilobolus Umbonatus Buller, Kenneth L. Poff
Some Factors Involved In Growth And Sporulation Of Pilobolus Crystallinus Tode And Pilobolus Umbonatus Buller, Kenneth L. Poff
Master's Theses
Pilobolus umbonatus Buller and P. crystallinus Tode grew normally in a nitrogen atmosphere but their sporagnia were non-pigmented. When palced in anaerobic jars along with obligately anaerobic and obligately aerobic bacteria, the fungi grew in the range of oxygen concentrations too low for growth of the aerobic bacterium, but high enough to prevent growth of the anaerobe. The fungi did not grow when the oxygen was depleted to the point that allowed growth of the anaerobic bacterium. Catalase was not produced by the hyphae and trophocysts which normally grow beneath the surface of the medium, but was present in the …

Embryology And Evolution, Malo Marius Amunson
Manuscript Thesis Collection
The proofs of evolution must be sought in the entire field of science. Direct proof is found in the study of Morphology, whose bases are comparative anatomy; embryology; in the study of paleontology, of geology, of geographical distribution, in the study of nature and experiments of today. In this vast field of direct proofs of evolution it is our purpose to present some of the evidences of evolution as furnished by one of these, namely, Comparative Embryology.
