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 …

Interdisciplinary Education In Dental Hygiene: A Pilot Project, Susan E. Zimmer, Linda Milson, Linda Laatsch

Clinical Lab Sciences Faculty Research and Publications

This study describes a five-hour interdisciplinary experience involving sophomore dental hygiene students, dental hygiene faculty and medical technology faculty. This experience met the objectives of interdisciplinary teaching while reinforcing and expanding on a present topic in a four-year dental hygiene curriculum.

The results of this experience are documented by pre- and post-testing and student evaluations. Statistical analysis of the test results along with student commentaries support interdisciplinary education as a viable and positive teaching approach. Student ability to correctly answer topic-related cognitive questions increased significantly while their understanding of the medical technology profession and its relationship to dental hygiene also …

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 …

Alternatives To Aversive Procedures With Animals In The Psychology Teaching Setting, Jeffrey A. Kelly

Experimentation Collection

In this paper, we will consider the treatment of laboratory animals in psychology instruction and will focus on practical alternatives to traditional practices that cause pain and distress to animals. While the discussion will draw on psychology for examples, many of the issues apply equally to the instruction of students in other courses of study, including medicine, veterinary medicine, biology, and physiology.

The Imbalance Between Experiment And Theory In Biology: The Need For Theory-Directed Modeling, M. L. Fidelman, D. C. Mikulecky

Experimentation Collection

In biological and biomedical research, the vast majority of resources are focused on conducting experiments. Most of these experiments utilize animals. Only a tiny amount of resources is spent on theory and modeling. It is our contention and the basic theme of this paper that the imbalance between theory and experiment in biology produces very poor science. The implications of which are that many of the experiments conducted have little real scientific meaning or value and, therefore, go hand-in-hand with unnecessary animal use and suffering. Given the finite resources available for research, the redirection of significant resources from an almost …
