Initial Characterization Of Coagulin Polymerization And A Novel Trypsin Inhibitor From Limulus Polyphemus, Maribeth Ann Donovan Jan 1990

Initial Characterization Of Coagulin Polymerization And A Novel Trypsin Inhibitor From Limulus Polyphemus, Maribeth Ann Donovan

Doctoral Dissertations

In the final step of coagulation in the horseshoe crab, coagulogen (M$\sb{\rm w}$ = 19,000, from sedimentation equilibrium) is converted by discrete proteolysis into its clottable form, coagulin. Coagulogen does not have a strong tendency to self-associate. In 0.1 M ammonium bicarbonate, 50 mM Tris-HCL (pH 8.1), trypsin generated coagulin rapidly associates to form a stable, solid gel. Polymerization is pH-dependent, with reversible depolymerization occurring in acid (midpoint pH 5.4). Sedimentation velocity analysis reveals that stable intermediates remain at pH 2.5, with 30-31 s being the predominant form along with monomer (1.89 s) and larger forms ($>$60 s). Near …


Endor And Eseem Studies Of A Cyanide Adduct Of Transferrin, Penny Ann Snetsinger Jan 1990

Endor And Eseem Studies Of A Cyanide Adduct Of Transferrin, Penny Ann Snetsinger

Doctoral Dissertations

Information about the ligand environment of the iron binding sites in a cyanide adduct of transferrin was obtained by an analysis of powder-type ENDOR and ESEEM spectra. The low-spin cyanide adduct of transferrin is formed only in the C-terminal site of the protein and is characterized by a rhombic EPR spectrum. Earlier work demonstrated that three cyanide groups are necessary to form the adduct, but it wasn't clear whether these groups were coordinated directly to the metal or to cationic sites on the protein. The ENDOR spectra of the $\sp{13}$CN adduct showed one set of $\sp{13}$C ENDOR resonances which probably …


Genetic Variability And Population Structure Of Eastern White Pine In A Two Hectare Stand, Durham, New Hampshire, Petr R. Brym Jan 1990

Genetic Variability And Population Structure Of Eastern White Pine In A Two Hectare Stand, Durham, New Hampshire, Petr R. Brym

Doctoral Dissertations

The genetic structure of a two hectare stand of eastern white pine (Pinus strobus L.) was studied by relating foliar allozyme composition of individual trees to tree location and age. Using starch gel electrophoresis, the trees were found to have variants for six of the seven enzymes analyzed. Trees of similar age and with common allozymes were found in clusters, suggesting that genetic structure existed in the stand. The genetic structure may have originated during establishment of several seedlings from common parents when openings were created in the canopy. Knowing that a genetic structure, such as that observed in this …


Changing Energy Futures: A Systems Approach To The Adoption Of Energy Alternatives In New Hampshire, Mark Edward Diffenderfer Jan 1990

Changing Energy Futures: A Systems Approach To The Adoption Of Energy Alternatives In New Hampshire, Mark Edward Diffenderfer

Doctoral Dissertations

In an attempt to develop a comprehensive approach to the study of the adoption of energy systems, this dissertation first critically examines a variety of approaches to this phenomenon, including market models of adoption, the adoption of innovations literature, and the social psychology of attitudes and behavior. Market models are seen as generally reductionistic and the argument is made that they fail to take into consideration a variety of non-cost considerations. The assumption here is that while price considerations play a role in this process, decisions are also affected by values and attitudes which are not directly incorporated into market …


Estimates Of Energy Expenditure In Women And A Biofeedback Device For Weight Loss, Sandra Rutter Jan 1990

Estimates Of Energy Expenditure In Women And A Biofeedback Device For Weight Loss, Sandra Rutter

Doctoral Dissertations

Researchers have been unable to discern the relationship between energy expenditure and obesity because there has been no reliable, unobtrusive method to capture daily activity. Single-plane accelerometers have been developed, using microcomputer technology, which may provide a means for measuring expenditure in human subjects. The Caltrac Personal Activity Computer$\sp\circler$ has shown high test-retest reliability and a strong relationship to several measures of expenditure in some laboratory tests. In Experiment 1, 40 university women (mean age = 19.15 yr) wore Caltracs during waking hours for either three or six consecutive days, with the devices programmed to count activity regardless of individual …


Breaking The Rules: Teaching And Learning Writing In The High School, Ann Bruthwell Vibert Jan 1990

Breaking The Rules: Teaching And Learning Writing In The High School, Ann Bruthwell Vibert

Doctoral Dissertations

This dissertation explores the development of student- and process-centered writing classrooms within the context of a traditionally structured, curriculum-centered high school. The focus of the study is on how teachers and students experience and address contradictions between assumptions implicit in writing process pedagogy and assumptions implicit in the structure and organization of the high school.

An eight-month ethnography of two high school English classrooms, the study is a descriptive narrative of the classroom and school events punctuated by the reflective comments of teachers and students in intensive and extensive interviews. The classrooms are "placed" within the school, the teachers within …


The Biosystematics Of Carex Section Scirpinae (Cyperaceae), Debra Ann Dunlop Jan 1990

The Biosystematics Of Carex Section Scirpinae (Cyperaceae), Debra Ann Dunlop

Doctoral Dissertations

Carex section Scirpinae is a small group of North American sedges that possess a dioecious breeding system, unispicate inflorescences and pubescent perigynia. Historically, ten different taxa had been recognized at the specific or infraspecific levels based primarily on morphological characters. Taxonomic problems in the group were related to the lack of a comprehensive monographic treatment. Floristic treatments were limited and focused only on a few regional taxa. Descriptions were often incomplete, lacking descriptions of staminate material or complicated by the inconsistent use of the terms phyllopodic and aphyllopodic. Patterns of variation in morphological characters across a wide geographic range were …


Characterization Of A Cytotoxin From Campylobacter Jejuni And Its Role In Pathogenicity, Sangeeta Mahajan Jan 1990

Characterization Of A Cytotoxin From Campylobacter Jejuni And Its Role In Pathogenicity, Sangeeta Mahajan

Doctoral Dissertations

Campylobacter jejuni is a major cause worldwide of human gastroenteritis. In this study, the pathogenicity of the organism was examined in fertile hens' eggs and the mortality data and histopathological findings induced by both the organism and bacteria-free filtered broth were similar. The absence in chick embryo tissues of either bacteria or an inflammatory infiltrate suggested a toxic etiology. A protein was obtained from the filtrate by gel electroelution and this was sensitive to heat, pH changes and trypsin treatment and was lethal for the fertile hen's egg. It showed cytotoxic effects in primary chick embryo fibroblast (PCEF), Chinese hamster …


Structural And Functional Characterization Of The Yeast General Transcriptional Activator Ccr4, Thomas M. Malvar Jan 1990

Structural And Functional Characterization Of The Yeast General Transcriptional Activator Ccr4, Thomas M. Malvar

Doctoral Dissertations

Transcription of the glucose-repressible ADH (ADH2 locus) in Saccharomyces cerevisiae is controlled by two regulatory pathways. The general transcriptional factors CCR4, CRE1, and CRE2 constitute the first pathway while the second pathway is comprised of the trans-activators ADR1 and CCR1. Both ADR1 and CCR1 act through upstream activation sequences (UAS) found in the 5$\sp\prime$-regulatory region of the ADH2 structual gene. In contrast, the action of CCR4, CRE1, and CRE2 is likely to be at sequences near the TATAA element of ADH2.

The CCR4 locus was precisely mapped on the left arm of chromosome I where it had previously been localized. …


Population Ecology And Feeding Biology Of Nudibranchs In Colonies Of The Hydroid Obelia Geniculata, Walter J. Lambert Jan 1990

Population Ecology And Feeding Biology Of Nudibranchs In Colonies Of The Hydroid Obelia Geniculata, Walter J. Lambert

Doctoral Dissertations

Kelp blades (Laminaria spp.) with colonies of Obelia geniculata were collected over a 28 month period from Cape Neddick, ME to document the epifaunal community and to determine the possible mechanisms allowing four nudibranch species to coexist. Regression analyses correlated the abundances of epifauna with habitat parameters. The feeding biology of nudibranchs was described. Density manipulations of nudibranchs in pair-wise behavioral interactions tested the effects of interference on the location of nudibranchs in the colony.

Obelia geniculata provides habitat and food for many invertebrate epifauna. The hydroid colony acts as the island for most species. Hydrocauli provide structure to motile …


The Impact Of Systemic Family Processes And Structures On Mental Illness And Family Violence, Al A. Shigo Jan 1990

The Impact Of Systemic Family Processes And Structures On Mental Illness And Family Violence, Al A. Shigo

Doctoral Dissertations

The relationship of both family structure and process variables to both mental illness and family violence are examined in this study. A non-clinical sample of 100 university student families and a clinical sample of 100 in-patient families at a psychiatric hospital are utilized. Both non-clinical and clinical samples are utilized with subjects of similar age. Within the broader context of General Systems Theory and family systems theory in particular, the inter-systemic variable of bounding and the intra-systemic variable of linking are tested in their relationships to both mental illness and family violence. Open, random, and closed family system types are …


Stimulus Configuration And The Perceived Rigidity Of Eight-Vertex Polyhedra, John Edward Sparrow Jan 1990

Stimulus Configuration And The Perceived Rigidity Of Eight-Vertex Polyhedra, John Edward Sparrow

Doctoral Dissertations

In a series of four experiments, subjects examined the perceived rigidity of rotating eight-vertex polyhedra. Four different categories of polyhedra were observed under parallel projection: (1) line drawings where the initial orientation appeared to be a cube (LN), though the depth components of the eight vertices were randomly positioned (upon rotation, it could be seen that the stimuli were not cubes); (2) line drawings where the vertices were randomly placed (LR); (3) vertex-only drawings where the initial orientation appeared to be a cube (VN), though the depth components of the eight vertices were randomly positioned; and (4) vertex-only drawings with …


Role Of Polyamines In Dna Synthesis Of Catharanthus Roseus Cells Grown In Suspension Culture, Rakesh Minocha, Subhash C. Minocha, Atsushi Komamine, Walter C. Shortle Jan 1990

Role Of Polyamines In Dna Synthesis Of Catharanthus Roseus Cells Grown In Suspension Culture, Rakesh Minocha, Subhash C. Minocha, Atsushi Komamine, Walter C. Shortle

Faculty Publications

The requirement for polyamines in the proliferation of cells was first demonstrated in bacteria (3). While significant progress has been made in this field using animal cell cultures, only preliminary studies have been reported with plant tissues. Serafini-Fracassini et al. (9) showed a marked increase in polyamine synthesis early during the G 1 phase, concomitant with the synthesis of RNA, following the break of dormancy in Helianthus tuberosus tuber tissue. A second phase of polyamine accumulation began during the progression of S phase. Torrigiani et al. (10) and Phillips et al. (7) later showed that all major polyamines peaked during …

Polyamine And Ethylene Biosynthesis In Relation To Somatic Embryogenesis In Carrot ( Daucus Carota L.) Cell Cultures, Subhash C. Minocha, Cheryl A. Robie, Akhtar Jamal Khan, Nancy S. Papa, Andrew I. Samuelsen, Rakesh Minocha

Faculty Publications

Carrot cell cultures provide a model experimental system for the analysis of biochemical and molecular events associated with morphogenesis in plants (3, 4, 5, 14). Among the biochemical changes accompanying somatic embryogenesis in this tissue is an increased biosynthesis ofpolyamines (1, 2, 7, 10, 11, 13). A variety of inhibitors of polyamine biosynthetic enzymes have been used to analyze the role of polyamines in somatic embryogenesis. A summary of our work on the effects of DFMO, DFMA, MGBG and CHAP on somatic embryogenesis, cellular polyamine levels, and activities of ADC, ODC, AdoMet decarboxylase, and AdoMet-synthetase in carrot cell cultures is …

Gills As Possible Accessory Circulatory Pumps In Limulus Polyphemus, Winsor H. Watson Iii, M. A. Freadman Dec 1989

Gills As Possible Accessory Circulatory Pumps In Limulus Polyphemus, Winsor H. Watson Iii, M. A. Freadman

Jackson Estuarine Laboratory

Heart electrical activity (ECGs), gill closer muscle potentials (EMGs), and blood pressures in the heart and the branchiocardiac canals, were measured in adult horseshoe crabs (Limulus polyphemus) during various activities. During ventilation, hyperventilation, and swimming, large transient increases in pressures (10-35 cm H2O) occur in the branchiocardiac canals, which carry blood from the gills to the heart. These pulses of positive pressure are related to, and apparently caused by, gill plate closing. During quiescent periods, with no ventilatory activity, there are no pressure pulses in the canals, but the pressure is still greater than zero. We found covariation of heart …

Second Messenger Systems Underlying Amine And Peptide Actions On Cardiac Muscle In The Horseshoe Crab, Limulus Polyphemus, Winsor H. Watson Iii, J. R. Groome Sep 1989

Second Messenger Systems Underlying Amine And Peptide Actions On Cardiac Muscle In The Horseshoe Crab, Limulus Polyphemus, Winsor H. Watson Iii, J. R. Groome

Jackson Estuarine Laboratory

The biochemical mechanisms by which octopamine, catecholamines and the peptide proctolin exert their actions on Limulus cardiac muscle were investigated. Amines produced long-lasting increases in the amplitude of contractions evoked by electrical stimulation. At 10(−5) mol l-1, the apparent order of potency for amine-induced increases in evoked contraction amplitude was dopamine approximately equal to octopamine greater than norepinephrine approximately equal to epinephrine. At this dose, amines produced long-lasting increases in the levels of cyclic AMP (octopamine greater than dopamine approximately equal to norepinephrine approximately equal to epinephrine), but not of cyclic GMP, in Limulus cardiac muscle. Like the amines, the …
