Concentrations Of Uranium Isotopes In Uranium Millers' And Miners' Tissues, United States Nuclear Regulatory Commission

Health

The alpha-emitting isotopes of uranium and thorium were determined in the lungs of 14 former uranium miners and in soft tissues and bones of three miners and two millers. These radionuclides were also determined in soft tissues and bones of seven normal controls. The average concentrations in pCi/kg wet weight in 17 former miners' lungs are as follows: U-238, 75; U-234, 80; Th-230, 79. Concentrations of each nuclide ranged from 2 to 325 pCi/kg. The average ratio of U-238/U-234 ws 0.92, ranging from 0.64 to 1.06. The mean ratio of Th-230/U-234 was 1.04, ranging from 0.33 to 3.54. The near …

Twenty-Seven Protein Polymorphisms By Two-Dimensional Electrophoresis Of Serum, Erythrocytes, And Fibroblasts In Two Pedigrees, David Goldman, Lynn R. Goldin, P. Rathnagiri, Stephen J. O'Brien, Janice A. Egeland, Carl R. Merril

Biology Faculty Articles

Twenty-seven independent polymorphic loci were detected by two-dimensional electrophoresis (2DE) of serum, erythrocytes, and fibroblasts in two large families and analyzed for linkage to classical genetic markers. We detected seven serum, four erythrocyte, and 17 fibroblast protein loci that exhibited charge variation in these two families and in a sample of unrelated individuals. The genetic basis of protein variants was confirmed by quantitative gene-dosage dependence and by conformance to Mendelian transmission in the two families, except for four rare variants for which transmission analysis was not possible. Linkage analysis demonstrated that each of the variants represent products of independent loci, …

A Rapid Concentration And Identification Technique For Human Malaria Infections Using A Mouse Model, Donald D. Barton

Loma Linda University Electronic Theses, Dissertations & Projects

Red blood cells infected with malaria parasites experience a change in density making them lighter (less dense). This paper reports a new, rapid diagnostic technique using this change in density in the infected red blood cell. It is not only easy to use, but it is also compatible with the technological conditions found where the malaria problem is most acute - in many developing countries of the world. A small sample of blood drawn from a simple finger stick can be concentrated and examined microscopically for malaria parasites within 10 minutes. The thick film slide preparation, presently used, takes a …

The Relationship Of Vitamins B-6 And B-12 To Plasma Homocysteine Levels In Men At Low- And High-Risk For Coronary Heart Disease, Marlene E. Swift

Loma Linda University Electronic Theses, Dissertations & Projects

There is evidence that homocysteine may be a factor in increasing the risk of coronary heart disease (CHD). To explore this relationship further, we assessed the interrelation of dietary vitamins B-6, B-12 and folate, and plasma pyridoxal-5'-phosphate and vitamin B-12 with plasma free and protein-bound homocysteine levels. Fasting blood and three-day dietary records were obtained from nine men low-risk (LR) and five at high-risk (HR) for CHD. The HR mean systolic blood pressure, total cholesterol (TC), and TC/cholesterol ratios were significantly higher than LR levels. Groups were comparable by age, weight, height, skinfolds, exercise, and smoking history. No significant difference …

The study population was comprised of 16 institutionalized elderly who were (a) oriented to person, place, and time; (b) mobile; and (c) physically able and willing to hold a live pet rabbit during 30 minutes of four group sessions. Researcher-designed tools and protocols were used in the study to record blood pressures, heart rates, and the number of social interactions during each group session. The subjects were randomly assigned to an experimental or a control group. Each group had …

The Effects Of Exercise On Cognitive Function In The Elderly, Pamela D. Thomas

MSN Research Projects

In order to determine the effect of exercise upon cognition of institutionalized elderly a quasi-experimental research approach was used. A sample of 20 was selected from two long-term care nursing facilities to make an experimental and a control group. The experimental group had a prescribed exercise plan followed by a cognition test while the control group received only the cognition test. The cognition test scores were analyzed using the ^ test statistic with a significance level of 0.05. Analysis of the data led the researcher to fail to reject the null hypothesis; however, a marginally significant trend for the experimental …

An Investigation Of The Relationship Between Premorbid Personality And Depression, William Essenburg

Dissertations

Depression is a significant mental health problem and has been studied extensively for decades. However, there is still disagreement among clinicians and researchers regarding the causes and psychodynamic processes of depression.

The purpose of this study was to investigate the relationship between premorbid personality and depression. Using the Millon Clinical Multiaxial Inventory (MCMI) and the Beck Depression Inventory, personality and depression measures were obtained from a sample of adult psychiatric inpatients during acute and remission phases of their hospitalization.

Results obtained indicated that the MCMI scales intended to measure premorbid personality during periods of acute psychiatric illness were sensitive to …

Recovery Of Helminths From Prehistoric Feces: The Cultural Ecology Of Ancient Parasitism, Karl J. Reinhard

Karl Reinhard Publications

Several helminth parasites have been recovered from archaeological sites on the Colorado Plateau. These include Ascaris, Trichuris, Enterobius, Moniliformis, and tapeworms in the families Hymenolepidae and Taeniidae. The recovery of these animals demonstrates that cross-temporal: comparison of parasitism between different prehistoric lifestyles is possible. Such comparison might elucidate the effects of changing lifestyle and subsistance pattern on human parasitism.

Desiccated feces recovered from archaelogical deposits were studied. Hunter-gatherer feces were selected from Dust Devil Cave in southeastern Utah. Agriculturalist feces were studied from Antelope House, a cave site in northeastern Arizona, and Salmon Ruins, a Pueblo …

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

MSN Research Projects

This study compared 23 nursing home residents’ and 23 nursing assistants’ control perceptions over the residents’ activities of daily living. Residents’ perceptions were measured with Chang’s Situational Control of Daily Activities (SCDA). Nursing assistants’ perceptions were measured by an investigator designed questionnaire, the Questionnaire of Activities of Daily Living (QADL). Scores of each group were compared using the ^ test which found both groups perceived a high degree of control over the residents’ activities. Based on this finding, the hypothesis that no significant difference in perceived control over residents’ daily activities exists between nursing home residents and nursing assistants was …

Metabolic Effect Of 3,3',5'-Triiodothyronine In Cultured Growth Hormone-Producing Rat Pituitary Tumor Cells. Evidence For A Unique Mechanism Of Thyroid Hormone Action., D L. St Germain

Dartmouth Scholarship

Physiologic levels of 3,3',5'-triiodothyronine (rT3) are generally believed to have minimal metabolic effects in the pituitary gland and other tissues. In the present studies, the regulatory role of rT3 and other thyroid hormones on iodothyronine 5'-deiodinase (I5'D) activity was studied in a growth hormone-producing rat pituitary tumor cell line (GH3 cells). I5'D activity was thiol-dependent and displayed nonlinear reaction kinetics suggesting the presence of two enzymatic processes, one having a low Michaelis constant (Km for thyroxine [T4] of 2 nM) and a second with a high Km value (0.9 microM). Growth of cells in hormone-depleted medium resulted in a two- …

Identification Of Sequences In The Herpes Simplex Virus Thymidine Kinase Gene Required For Efficient Processing And Polyadenylation., Charles N. Cole, Terryl P. Stacy

Dartmouth Scholarship

The herpes simplex virus (HSV) type 1 thymidine kinase gene (tk) was resected from its 3' end with BAL 31 exonuclease. Two sets of plasmids were isolated that lacked information distal to the two copies of the hexanucleotide 5'-AATAAA-3' located at the 3' end of the HSV tk gene. The presence of a simian virus 40 origin of DNA replication in each plasmid facilitated analysis of patterns of transcription in transfected Cos-1 monkey cells. Transcription analyses were performed with an S1 nuclease protection assay. Efficient processing and polyadenylation at the normal site still occurred when all sequences more than 44 …

High Rates Of Photosynthesis In The Desert Shrub Chrysothamnus Nauseosus Ssp. Albicaulis, Tim D. Davis, N. Sankhla, W. R. Andersen, D. J. Weber, B. N. Smith

Great Basin Naturalist

Basic aspects of photosynthesis were investigated in white rubber rabbitbrush (Chrysothamnus nauseosus (Pallas) Britt. ssp. albicaulis), a common C₃ deciduous shrub native to arid regions of the western U.S. Under favorable field conditions, net photosynthesis (P_n) ranged from 36 to 73 mg CO₂ · dm ⁻² · hr⁻¹, which is relatively high for a woody species. The leaves from the actively growing flowering shoots exhibited higher P_n than those on the vegetative shoots. P_n also varied according to the age of the leaves and the location of the plants. P …

Biological Sciences Theses & Dissertations

The distribution and concentration of Ceratium species, between Cape Hatteras, North Carolina and Long Island, New York ls discussed in relation to specific physical factors and the development of a phytoplankton bloom. The progression of high Ceratium counts Is discussed for the Bight areas of New York, Delaware, and the Chesapeake Bay (April through June). The concentration of Ceratium species declined after June, with highest concentrations along the New York and Delaware coast-lines. Coastal regions (less than 12 km from shore) were associated with high concentrations of several species. Path and regression analysis were used to relate physical factors and …

Enteroclysis For The Examination Of The Small Bowel, Robert D. Halpert, Peter J. Feczko, Cathrine E. Keller, Judith Iorio

Henry Ford Hospital Medical Journal

Detailed evaluation of the small bowel is difficult because of its inaccessibility. The small bowel follow-through examination using barium, has low diagnostic sensitivity. Enteroclysis, the injection of contrast material through a duodenal or jejunal tube, offers a newer and highly sensitive method of radiological evaluation. Our paper describes the technique, clinical indications, and side effects of enteroclysis.

Artificial Intelligence And Image Processing, Laurens V. Ackerman, Matthew W. Burke

Henry Ford Hospital Medical Journal

The evolution of artificial intelligence since the 1950s is discussed, especially as it is being applied in radiology to image processing. Developments in artificial intelligence are now being used to provide a new approach to image processing. Initially, the computer dealt with numeric representations using languages such as FORTRAN and BASIC. Now symbolic languages such as LISP and PROLOG have expanded the use of the computer into nonnumeric symbolic reasoning that is just being applied to image understanding. This paper explains the new languages and their application to image understanding.

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 …

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. …

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% …
