Haemophilus Influenzae In Adults: An Analysis Of Incidence, Serotype, Biotype, Beta-Lactamase Production And Clinical Spectrum, Mildred Ramsey Norris

MSN Research Projects

A selective medium, chocolate agar with vancomycin, bacitracin, and clindamycin, was used to enhance the recovery of Haemophilus influenzae from adult patients. Cultures of the 634 respiratory specimens yielded 130 (20.5 percent) H. influenzae isolates, representing 93 patients. The serotype, biotype, and Beta-lactamase production of all isolates were determined. Of 103 distinct isolates, nine percent were serotypable and included serogroups a ,b ,d ,and e. Although biotypes I, II, III, V, and VI were represented, 81.5 percent of the isolates were in the II/III group. Twenty-six percent of the isolates were Beta-lactamase producers and, therefore, ampicillin resistant. The clinical characteristics …

A Comparison Of Nursing Home Residents And Nursing Personnel In Terms Of Perceived Control Over The Resident’S Activities Of Daily Living, Patricia A. Kohler

A researcher-designed test measuring sexual knowledge and attitudes was administered to 72 nursing home employees. These health care providers included registered nurses, licensed practical nurses, and nurse's aides. The researcher hypothesized that there would be no significant correlation between the knowledge and attitude scores of nursing home personnel on a test about sexuality in the elderly. Data were analyzed using the Pearson r_ statistic and the findings led to rejection of the null hypothesis. The researcher concluded that the more knowledge about …

Training Behavioral Assessment Interviewers: A Comparison Of Two Procedures, Raymond G. Miltenberger

Dissertations

Two procedures were used to teach behavioral assessment interviewing skills; a training manual and a one-to-one training procedure consisting of instructions, modeling, rehearsal and feedback. Four subjects, two graduate students and two seniors, were trained with each procedure. Interviewing skills were recorded in simulated assessment interviews conducted by each subject across baseline and treatment conditions. Each training procedure was evaluated in a multiple baseline across subjects design. The results showed that both procedures were equally effective for training behavioral interviewing skills, with all subjects reaching a level of 90-100% correct responding. Finally, a group of experts in behavior analysis rated …

Diagnosis Of Dyslexia: The Utility Of The Boder Test Of Reading-Spelling Patterns, A Representative Case Study Approach, Donna Montei

Dissertations

The first purpose of the dissertation was to study the relationship between Boder test diagnosis (dysphonetic dyslexia) and hemisphere arousal with a representative subject. The relationship between standard methods of diagnosis and Boder diagnosis was studied with five additional subjects. The "dysphonetic" subject was measured with electroencephalogram biofeedback equipment and the Wechsler Intelligence Scale for Children-Revised (WISC-R) and demonstrated higher arousal in the left hemisphere than the right hemisphere. Four of the five other subjects were diagnosed differently by the Boder test from diagnoses obtained through standard psychological test batteries. The results suggest that the Boder typology constructs may be …

The Effect Of Subject Expectations Of "Hypnosis" Upon The Vividness Of Visual Imagery, Kayla Mae Nilsson

Dissertations and Theses

There is no consensus of how hypnosis works. The two major theorists in hypnosis research, the Phenomenologists and the Behaviorists, disagree on this issue. The Phenomenologists consider individual talent and change of the state of consciousness the key to how hypnosis works. The Behaviorists consider the social situation and the roles taken by the experimenter and subject, especially the subject's expectations of hypnosis, the mainspring of the hypnotic process. Subject expectations of hypnosis have been found to affect the final results of hypnosis experiments. An experiment was conducted to gain further insight into subject expectations of hypnosis, and how these …

Lymph Flow In Newborn Lambs : Effects Of Change In Osmolality, Debra S. Wickman

Loma Linda University Electronic Theses, Dissertations & Projects

Recent investigations have shown that volume loading and alterations in body fluid osmolality cause rapid shifts throughout the body's fluid compartments in the adult dog. The lymph system has been found to be a vital link in the body's ability to compensate for excess fluid, and thus provides a strong defense against edema formation (Brace and Power, 1981; 1983). There have been no previous studies dealing with the investigation of whole-body lymph flow responses in the newborn. The purpose of this experimental research was to perform a systematic study into the whole-body lymph responses of newborn lambs to the particular …

Corrosion Of Orthodontic Brackets: Cost, Cold Worked, And Powdered Metal, Timothy C. Ballweber

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study is to evaluate the relative corrosion rates of 316-L stainless steel cast metal, cold worked, and powdered metal brackets. This is done using potentiodynamic anodic polarization to measure the voltage difference between the samples and a reference electrode. Corrosion layers effect current flow and by plotting how the current responds to an applied voltage it is possible to determine the corrosion rate of a sample. The point at where the applied voltage breaks down the passivation or oxidation layer is recorded and the relative corrosion rate is figured using the formula: Corrosion Rate _(mpy) (in …

Cryptosporidiosis In The Immunosuppressed Mouse And In Cell Culture, Mercy Prabhu Das

Loma Linda University Electronic Theses, Dissertations & Projects

Cryptosporidiosis is a parasitic infection primarily of animals that has been recently recognized as an important disease in immunocompromised humans. Most cases to date have occurred in patients with acquired immunodeficiency syndrome (AIDS). Persons with abnormal humoral or cellular immune function, and even normal subjects, have also been affected.

To determine whether or not mice, when experimentally immunosuppressed, would develop cryptosporidiosis, a test was designed using the AKR/J strain. This strain was selected because, it was previously reported that it was the strain shown to respond most readily to the production of disease caused by the opportunistic protozoan, Pneumocystis carinii …

Stability In Mechanical Expansion Of The Maxilla With Surgical/Mechanical Expansion Of The Mandible In An Adult Baboon, Robert D. Mitchell

Loma Linda University Electronic Theses, Dissertations & Projects

Expansion of the maxilla at the midpalatal suture has had much investigation and is a recognized option in orthodontic therapy. Lateral expansions of the mandible through surgical separation at the symphysis have been done in animal studies. A combination of these procedures has not yet been done together.

The purpose of this study was to expand both the maxilla and the mandible of a baboon simultaneously while maintaining occlusion. The amount of expansion and stability was studied using photographs, models, cephalograms, and tetracycline bone labels using U.V. microscopy.

A young adult baboon with full dentition and normal occlusion was used. …

Psychosocial And Behavioral Characteristics Of Ischemic Heart Disease Patients: Their Measurement And Relationship To Adherence In An Intensive Nutrition Education Program, Lynn Caldwell

Loma Linda University Electronic Theses, Dissertations & Projects

Nonadherence to therapeutic regimens which necessitate major lifestyle change is recognized as one of the most serious problems in medical practice today. Attempts to prevent and control chronic disease, including the development and progression of cardiovascular disease, are only effective when recommendations to the patient are carried out. Few studies have systematically studied the relationship of psychosocial and behavioral factors to adherence outside the theoretical framework of a specific behavioral model; no study has done so with a carefully measured diet as the outcome variable in a controlled prospective clinical trial with patients suffering from cardiovascular disease.

This study, as …

Analysis Of The Time-Dependent Force Loss Of Orthodontic Wires, David Jaekwan Jo

Loma Linda University Electronic Theses, Dissertations & Projects

In testing the force loss of five brands of orthodontic wire under a variety of stress modes, it was found that; 1) heat treatment reduced force loss in all the wires; 2) the amount of time-dependent force loss increased when the magnitude of force was raised.

A further indication was that a sharp bend on the tested wire did not affect force loss. Force applied to unwind a loop produced force losses from 180 to 350% above the loss that occurred when force was applied to wind a loop.

The force loss data collected during a 72-hour period was analyzed …

A Study Of Transferable Antibiotic Resistance In Enteric Bacteria, Charles H. Regeski

Loma Linda University Electronic Theses, Dissertations & Projects

A group of 48 enteric bacteria was selected from a total of 170 at Loma Linda University Medical Center because of resistance to three or more antibiotics. They were examined to see if any of the antibiotic resistances were transferred by conjugation to either of two recipient bacteria. These were a restrictionless, antibiotic sensitive, azide resistant mutant of Escherichia coli K 12 designated E. coli 1228 and a similar phenotypic strain of Salmonella typhimurium LT2 designated LB 5000. Forty-three transferred one or more antibiotic resistances to either or both recipients, a frequency of 25.3% of the total bacteria and 89.6% …

Evaluation Of The Modulus Of Elasticity Of Stainless Steel Orthodontic Wire By The Acoustic Pulse-Propagation Technique, John Rick Neilson

Loma Linda University Electronic Theses, Dissertations & Projects

Confusion exists in the orthodontic literature when the modulus of elasticity of standard orthodontic wire is reported to either increase, decrease, or remain constant when that wire is heat treated or work hardening.

The objectives of this work include: 1. Introducing the acoustic pulse-propagation technique as a test for determining the modulus of elasticity in orthodontic wire, and 2. Determining if the modulus of elasticity of stainless steel orthodontic wire changes when a wire is subjected to heat treatment and work hardening.

Five sizes of stainless steel wire were evaluated: .014, .016, & .018 inch round, .016 x .016 inch …

Predictive Value Of Radiographic Analysis Of Menton, Hyoid Bone, And The Third Cervical Vertebra Angle, Kalfred G.S. Chun

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study is to determine if the hyoid bone could be used as a reliable and stable reference landmark. Previous researchers have used cranial landmarks to determine the hyoid bone position. The results of these studies have shown a large variability in hyoid position. To determine the hyoid bone position, an analysis called the hyoid triangle was used. The hyoid triangle is formed by joining the cephalometric points retrognathion (the most inferior posterior point on the mandibular symphysis), hyoidale (the most superior anterior point on the body of the hyoid bone), and C3 (the most anterior inferior …

Aspects Of Cardiovascular Oxygen Transport In Vertebrates, Michael Scott Hedrick

Dissertations and Theses

The hematological and rheological characteristics of blood from a number of vertebrates was compared to assess possible species differences in blood viscosity that may influence cardiovascular oxygen transport. Nucleated red blood cells (RBCs) were more viscous (measured by cone-plate viscometry) in comparison with enucleate (mammalian) RBCs at hematocrits greater than 40% when measured at equivalent temperatures. The lower viscosity of enucleate RBCs is attributed to an enhanced deformability of enucleate cells in comparison to nucleated cells.

The Effect Of Interpolated Continuous Reinforcement Following Fixed Ratio Reinforcement On Resistance To Extinction, Beverly B. Conway

Graduate Theses

The effect on response rates during extinction of interpolating varying numbers of continuous reinforcement sessions after seven fixed ratio-25 sessions was investigated. Rats received either seven, fourteen, or twenty-one sessions of continuous reinforcement. All rats then received seven sessions of extinction. There were three rats in each group. All sessions were thirty minutes long. The results showed rats receiving the CRF schedule for fourteen sessions make the most responses during extinction. Rats receiving the CRF schedule for fourteen sessions make the most responses during extinction. Rats receiving the CRF schedule for twenty-one sessions made fewer responses during extinction. Taken alone …
