Chemiosmotic Properties Of Isolated Secretory Granules From Parotid Glands Of Normal And Isoproterenol Treated Rats, Peter Raymond Arvan

Yale Medicine Thesis Digital Library

Secretory granule fractions were prepared isoosmotically from the parotid glands of normal rats and from rats that had received repeated injections of isoproterenol. These granules, purified extensively, are stable after isolation, making it possible to study biophysical parameters which may relate to their role in intracellular transport and secretion.Normal parotid granules have an internal pH of (TURN)6.8 and a low ionic permeability with respect to internal buffering capacity. By contrast, granules from the treated rats have an internal pH ranging from (TURN)7.7 in (0.3 M) sucrose media to (TURN)7.1 in (100 mM) KCl media; suggesting a large ionic permeability with …

Detailed Description And Nomenclature Of High Resolution G-Banded Horse Chromosomes And Cytogenetic Analysis Of Hereditary Multiple Exostosis In Horses, Alma Maciulis

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A reliable technique for obtaining late prophase, prometaphase and greater numbers of metaphase chromosomes is presented. The increased number of mitoses and high resolution chromosomes were obtained using a modification of the typical three-day blood culture technique in which the cell cycle was temporarily blocked at the G₁-s border with methotrexate. A high resolution G-band idiogram is presented using a system similar to the standardization of human chromosomes. The use of this technique and system of nomenclature will facilitate routine analyses of horse chromosomes and provide a basis for the identification and recording of chromosome aberrations in this …

Adolescent Egocentrism And Its Relationship To Parenting Styles And The Development Of Formal Operational Thought, Theo A. Riley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A predicted association between family relations and cognitive development and the emergence of adolescent egocentrism was explored in this study. A sample of seventh grade boys (n=131) and girls (n=120) completed Elkind and Bowen's Imaginary Audience Scale (a measure of egocentrism) and selected items from Heilbrun's Parent-Child Interaction Rating Scale and Schaefer's Parent-Behavior Inventory. A modified version of Lawson's Classroom Test of Formal Operations was used to measure cognitive development. Contrary to a theoretical based hypothesis a negative rather than positive relationship was found between level of formal operational thought egocentrism. For parenting style, perceived rejection/control …

Protein Recovery And Coagulation Properties Of Commercial And Fractionated Milk Clotting Enzymes, Khalida A. Shaker

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Protein recovery and coagulation properties of five commercial and fractionated milk clotting enzymes were studied. The fractionated enzymes were Sephadex G-100 fractions of the commercial enzymes. Milk clotting activity of each fraction was tested using Berridge substrate. All fractions from each preparation which had milk clotting activity as measured with the Formagraph were collected and pooled. These samples and the original enzyme preparations were used to coagulate milk. Percent of protein lost in whey was determined by Kjeldahl.

Survival Of Porcine Pepsin During Cheddar Cheese Making And Its Effect On Casein During Cheese Ripening, Gheyath H. Majeed

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A modification of a linear diffusion test for measuring milk clotting enzymes at concentrations of 1 x 10^-4 to 1 x 10^-1 chymosin units/ ml was developed to permit quantitative assay of porcine pepsin in Cheddar cheese with a standard deviation of 6%. The amount of porcine pepsin retained in Cheddar cheese curd was dependent on pH of milk at setting. Milk at pH 6.6, 6.4, 6.2, and 6.0 was set with porcine pepsin, acidified with lactic acid and glucono-~-lactone and made into Cheddar cheese. After pressing the corresponding curd contained 0, 3.64+0 .12 %, 4.79+0.52%, and 5.94+0.30% …

Evaluation And Improvement Of Coagulation Properties Of Milk For Manufacturing, Leslie M. Okigbo

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A rugged and sensitive instrument "Vatimer" was developed to evaluate the coagulation properties of milk in cheese vats. Microvolt signals from the instrument varied with standing-wave motion of milk, forces arising from coagulation, curd firming, curd syneresis and also clean-in-place spray forces. Curd firmness at cutting varied three to four fold in commercial Cheddar cheesemaking operations.

The Formagraph instrument was used to select individual cow milk samples with good and poor chymosin-coagulation characteristics from the Utah State University Holstein herd. Blending 50% good-, and 50% poor-coagulating samples did not improve average coagulation properties of poor samples. Higher chymosin concentration caused …

Finger tapping and CVC syllable repetition measures of 7 four to eight year old fluent and disfluent children and their mothers were evaluated. Perceptual ratings of speech rate and effort level were also completed by the children, their mothers, and nine graduate students. These procedures were used to test hypotheses that mean interval durations for tapping and for speech, and perceptual ratings of speech rate and effort level are individual in nature.

Results indicated that the subjects1 measures of mean interval durations for tapping and for speech as estimates of rhythmicity, and perceptual ratings of speech rate and effort level …

The Use Of Alternative Behaviors, Covert Sensitization And A Package Intervention In Treatment Of Bulimia, Janice Marie Arone

Masters Theses

Bulimia is a complex eating disorder that involves bouts of binge eating which are usually followed by a purge to rid the individual of the unwanted food. This disorder occurs primarily in females and may lead to several medical and psychological complications. The efficacy of two single component treatments and a package intervention designed to decrease variables related to binge eating were investigated with three bulimic females. The results of the research indicated that individuals who were exposed to the package intervention experienced the largest decrements in the binge eating when compared to the single component procedures.

The Problem Of Reductionism In Theories Of Hemispheric Specialization And Recovery Of Functions, Grant Jackson Butterbaugh

Masters Theses

A selective review of functional and anatomical hemispheric asymmetries in humans confirms the doctrine of hemispheric specialization. However, the post-insult phenomenon of recovery of functions challenges theories that posit too strict a correspondence between anatomical structures and functions. Follow-up studies on hemispherectomized and hemidecorticated patients, who later recovered language, support a hypothesis of hemispheric redundancy, rather than "invariant" hemispheric specialization for language. Thus, through an evolutionary selection process, the brain may have developed as two potentially similar organs. Neuropsychological research on recovery phenomena is criticized as neglecting environmental contributions to recovery. Several models of hemispheric specialization are compared with recovery …

A Comparison Of The Effects Of Student-Generated Versus Instructor-Generated Questions On The Comprehension Of Written Material, Helen Diann Pratt

The Relationship Between Thought Disorder And The Diagnosis Of Schizophrenia, David Frank Fatzinger

Dissertations

The diagnosis of schizophrenia has been considered unreliable, especially when derived by psychiatric interview. Thought disorder is one symptom that has been accepted by most clinicians as a major indicator of schizophrenia. The purpose of this study was to examine the relationship between thought disorder and the diagnosis of schizophrenia in a state hospital setting.

The sample consisted of 88 patients, 58 males (mean age = 32.0) and 30 females (mean age = 38.6) and was gathered from newly admitted patients in a large state hospital. Thought disorder was measured by the Whitaker Index of Schizophrenic Thinking (WIST) Form A, …

Mothers' Intervention Strategies In A Structured Question-Answer Dialogue, Marcia C. Hill

Masters Theses

Language intervention strategies of the mothers of ten normal and ten language-impaired children were compared. An experimenter asked each child questions of varying difficulty about a storybook, in the presence of the mother, who was free to help her child as needed. Both the children's and mothers' utterances were coded. The frequency and types of mothers' strategies were analyzed. The analysis revealed that mothers of normal children intervened significantly more often than mothers of language -impaired children, when all interventions were considered. However, the differences were not significant when only interventions related directly to the predetermined questions were considered. The …

Community Mental Health Attitudes, Fenimore William Johnson

Dissertations

The purpose of this study was to compare community mental health attitudes of the past and the present, and between mental health workers and the public. The results indicate that the public is better informed and more favorably disposed toward the mentally ill today than was true several decades ago. Some stereotypes persist, however, and the mentally ill are still regarded less favorably than are other disability groups. Mental health workers and the public appear to be similar in their endorsement of a medical approach to treatment, although the former endorse more strongly a community-based treatment orientation. There was no …

Investigation Of The Coenzyme Binding Site Of Lactate Dehydrogenase From Chicken Muscle, Jia-Hwei Lin

Chemistry & Biochemistry Theses & Dissertations

Investigation of the coenzyme binding site of lactate dehydrogenase was approached by using coenzyme analogs. Inhibition studies of this enzyme using n-alkylphosphates as coenzyme analogs were performed with a fluorometric method. The results showed that all of the n-alkylphosphates were competitive inhibitors with respect to NAD⁺.

The n-alkyl-ADPs were synthesized from AMP and dicycloheaylammonium salts of n-alkylphosphates. The synthetic compounds were subjected to NMR spectroscopic studies, thin layer chromatography and determination of the ratio of adenosine moiety to phosphate groups. The results indicated that the synthetic compounds were n-alkyl-ADPs.

These synthetic compounds were used as coenzyme analogs in …

A Method For The Comparison Of Hdl Containing Apoprotein E And Hdl Cholesterol, Steven A. Knizner

Chemistry & Biochemistry Theses & Dissertations

Human serum high density lipoproteins (HDL) were isolated by preparative salt density gradient ultracentrifugation and analyzed further by heparin-sepharose affinity chromatography. Separation of the major classes of serum lipoproteins was achieved after a single ultracentrifugation on a salt density gradient at 272,000 x g for 36 hours in a swinging bucket rotor. After isolation, the total HDL was subdivided into HDL containing apoprotein E and HDL without this apoprotein by heparin-sepharose affinity chromatography. Relative amounts of these subclasses were then calculated.

HDL-cholesterol was measured after precipitation of LDL and VLDL by phosphotungstic acid and magnesium. The statistical relationship between HDL …

Developmental Sentence Scoring: A Comparative Study Conducted In Portland, Oregon, Kathryn Marie Mccluskey

Dissertations and Theses

The purpose of this investigation was to replicate the study conducted by Lee and Canter (1971) and Lee (1974a) to determine if a significant difference among the scores in the two studies existed due to geographical location, and to initiate the establishment of norms for the Portland, Oregon geographical area. Forty children, selected on the basis of chronological age (4.0 to 4.11 years), normal receptive vocabulary skills, normal hearing, and a monolingual background, participated as subjects. A language sample of fifty utterances was elicited from each child and analyzed according to the Developmental Sentence Scoring (DSS) procedure.

Pre-Hospital Airway Management : A Comparison Of Esophageal And Endotracheal Intubation, Roger Phillips

Yale Medicine Thesis Digital Library

In the late 1960's, a new method for advanced airway management in the pre-hospital setting, the esophageal obturator airway (EOA), was introduced. Ever since, it has been the subject of much discussion over whether it was an effective replacement or alternative to the device traditionally used for airway protection, the endotracheal (ET) tube. Much of the comment has been in the form of personal opinion and anecdotal reports. Each device is in use by paramedics operating out of two hospitals in southern Connecticut, the EOA at Yale New Haven Hospital and the ET at Norwalk Hospital. The ambulance and emergency …
