Harold W. Manter Laboratory of Parasitology: Library Materials

We report the results of molecular analysis of 39 isolates of Cryptosporidium parvum from human and bovine sources in nine human outbreaks and from bovine sources from a wide geographic distribution. All 39 isolates could be divided into either of two genotypes, on the basis of genetic polymorphism observed at the thrombospondin-related adhesion protein (TRAP-C2) locus. Genotype 1 was observed only in isolates from humans. Genotype 2, however, was seen in calf isolates and in isolates from a subset of human patients who reported direct exposure to infected cattle or consumed items thought to be contaminated with cattle feces. Furthermore, …


Evaluation Of Accelerated Plethysmography As A Measure Of Health And Fitness, Angela Marie Humble Nov 1997

Evaluation Of Accelerated Plethysmography As A Measure Of Health And Fitness, Angela Marie Humble

Dissertations and Theses

Plethysmography is a technique used for measuring alterations in the volume of organs or limbs. Japanese researchers have developed a relatively new application of plethysmography (accelerated plethysmography) that uses information from the pulse wave measured at the fingertip to make inferences about health and fitness status. The instrument used to collect data -- the Precaregraph (accelerated plethysmograph) -- provides an accelerated pulse waveform and APG index, a mathematical representation of the waveform. It was the purpose of this study to evaluate the validity of the Precaregraph by examining the relationship between the APG index and previously validated measures of health …


The General Well-Being Of Recreational Drug Users: A Sub-Analysis Of The Drugnet Survey, Jennifer Reneau Nov 1997

The General Well-Being Of Recreational Drug Users: A Sub-Analysis Of The Drugnet Survey, Jennifer Reneau

Masters Theses & Specialist Projects

Issues related to substance use/abuse and mental health are significant public health concerns. Substance abuse is considered an individual and community mental health problem. The relationship between substance use and positive mental well-being, however, is less well understood. The purpose of this study was to describe the mental well-being of a sample of occasional, recreational drug users. Drugnet was an on-line survey of recreational drug use by non-deviant adults via the WWW. Volunteer subjects completed the survey over the internet between March and September 1997. Mental health was assessed utilizing the General Well-being Schedule (GWBS). A complete demographic profile of …


Triazine Herbicide Exposure And Breast Cancer Incidence: An Ecologic Study Of Kentucky Counties, Michele A. Kettles, Steven R. Browning, Timothy Scott Prince, Sanford W. Horstman Nov 1997

Triazine Herbicide Exposure And Breast Cancer Incidence: An Ecologic Study Of Kentucky Counties, Michele A. Kettles, Steven R. Browning, Timothy Scott Prince, Sanford W. Horstman

Preventive Medicine and Environmental Health Faculty Publications

The incidence of breast cancer in the United States has steadily increased for the past three decades. Exposure to excess estrogen, in both natural and synthetic forms, has been implicated as a risk factor for the development of this disease. Considerable interest has been focused on organochlorines, such as the triazine herbicides, and their possible role in the initiation or promotion of human breast cancer. To explore this relationship, an ecologic study of Kentucky counties was designed. Exposure to triazines was estimated by use of water contamination data, corn crop production, and pesticide use data. A summary index of triazine …

Farmer Crushed When Run Over By Tractor And Disc, Kentucky Injury Prevention And Research Center Oct 1997

Farmer Crushed When Run Over By Tractor And Disc, Kentucky Injury Prevention And Research Center

Fatality Case Reports--Tractors/Logging

A 75-year-old farmer was killed when he was run over by a tractor and disc attachment. The farmer attempted to start the engine on a tractor while he stood on the ground beside it, a practice which was not unusual for him. The transmission had been left in gear and when the ignition was started the tractor lurched forward knocking the victim to the ground. The tractor continued to move forward, running over the victim. His wife went to search for him when she realized he had been gone from the house for quite some time. She found him in …

Preventive Medicine and Environmental Health Faculty Publications

Agriculture has one of the highest occupational fatality rates of all industries in the United States (1). Tractors and other types of agricultural equipment account for a large proportion of these fatalities, and farm-tractor rollovers account for approximately 130 work-related deaths each year in the United States (2). Although rollover protective structures (ROPS) are effective in protecting tractor operators from fatal injuries during rollovers (3-5), most tractors in the United States are not equipped with ROPS (4-7). Beginning in 1985, tractor manufacturers in the United Sates agreed to sell only tractors with ROPS; however, many older tractors without ROPS remain …

Attitudes Toward Sexuality And Sexual Behaviors Of Asian-American Adolescents: Implications For Risk Of Hiv Infection, Connie S. Chan Sep 1997

Attitudes Toward Sexuality And Sexual Behaviors Of Asian-American Adolescents: Implications For Risk Of Hiv Infection, Connie S. Chan

Institute for Asian American Studies Publications

Until 1990, Asian Americans represented an ethnic minority group that was perceived to be at lower risk than African Americans or Hispanics/Latinos for HIV infection, the presumed causal agent for AIDS. Reasons cited for this perception include behavioral differences in intravenous drug use, sexual behavioral habits, and underidentification of AIDS cases. However, in urban areas such as San Francisco, Toronto, New York, Boston, Los Angeles, and Seattle, where Asians have immigrated and settled in large numbers, cases of HIV infection and AIDS have begun to increase dramatically, perhaps reflecting the rise in the number of AIDS cases in Asia. In …

The Place Of Persons With Disabilities In Rotuman Society, Jan Rensel, Alan Howard Sep 1997

The Place Of Persons With Disabilities In Rotuman Society, Jan Rensel, Alan Howard

Pacific Studies

In Rotuma, as in many other small, face-to-face societies, persons with disabilities are treated not as members of categories based on their conditions, but as individuals having whole constellations of characteristics and interpersonal histories. Their roles are not scripted on the basis of disabilities, but patterned by a number of key cultural principles that guide all relationships, including notions of immanent justice for wrongdoing, expectations of generosity and reciprocity, personal autonomy, and concern for family honor. Case studies and analyses of exchange interactions are presented to illustrate these points.


Consumer Debt, Alcohol Use, And Domestic Violence In Guam, Thomas K. Pinhey, Daniel A. Lennon, Nicholas A. Pinhey Sep 1997

Consumer Debt, Alcohol Use, And Domestic Violence In Guam, Thomas K. Pinhey, Daniel A. Lennon, Nicholas A. Pinhey

Pacific Studies

Using community-level economic and crime data derived from secondary sources, this brief study explores the relationships between consumer debt, alcohol use, and domestic violence in Guam for the years 1982 through 1993. The results of the analysis indicate that higher levels of consumer debt are strongly related to greater alcohol consumption and domestic violence, thus suggesting that “financial strain” may be an important variable for understanding patterns of substance abuse and family violence in Guam. The implications of these results for theory and future research on substance abuse and domestic violence are also discussed.

The Relationship Between Meaning In Life And The Occurrence Of Drug Abuse: An Epidemiological Retrospective Study, Ben Howard

Masters Theses & Specialist Projects

Humans have been using plant-derived drugs for as long as we have recorded history. Significant negative consequences related to drug abuse have occurred in the areas of health, social issues, family relations, legal systems, and economic productivity. The purpose of this study was to explore the relationship between meaning in life and drug abuse. An epidemiological, retrospective study was performed to compare personal meaning in life between individuals receiving inpatient treatment for drug abuse and a group of non-drug abusing controls. Study participants completed the Purpose-In-Life Test and Life Attitude Profile-Revised. On both instruments, the inpatient drug abusing subjects were …
