1. ENVIRONMENTAL GENETICS
Early Work in Environmental Mutagenesis
Before coming to NYCPM, I was on the faculty at New York Medical College. There, I was associated with the research team of Dr. Herbert Rosenkrantz (formerly of Columbia P&S). We studied the genetic effects of environmental chemicals using the Ames Assay and especially the Pol A Assay (Refs 12-19). I have utilized this Assay in the study of 42 carcinogens and non-carcinogens for the International Collaborative Program (17). I have worked with the Ames Assay as part of the National Cancer Institute’s four-laboratory collaborative study.
In addition, I was a member of the U.S. Environmental Protection Agency’s Gene- Tox Program, serving on the Repair Deficient Bacterial Assay Work Group, to evaluate the results and methodologies of these tests. I was the senior author of the Gene- Tox report (16) and presented the findings of the Work Group at the Conference held at the National Academy of Sciences (15). I have done numerous evaluative studies for the International Commission for the Protection against Environmental Mutagens and Carcinogens (ICPEMC).
Current work on new assay system
At the New York College of Podiatric Medicine, I established the Laboratory of Environmental Genetics. I received a grant from the March of Dimes for the “Development and Utilization of a Microbial Assay System for the Detection of Environmental Teratogens that Act on Genetic Regulatory Mechanisms”. The new assay I developed has been has been my primary area of interest since then. This early work was presented at an ASM Meeting (21).
A grant was received from the College to expand this work to new methodologies (Development and Utilization of a Microtiter Assay System for the Detection of Environmental Carcinogens that Act on Genetic Regulatory Mechanisms”). I presented results of my studies at Meetings of the AAAS and ASM (34-36)
Future Plans
My plan is to continue these studies, In particular, I have observed that the addition of certain chemicals in combination can enhance or reverse the effect of the initial gene-affecting agent. This opens up the possibility of new approaches to the development of chemotherapeutic agents and, at the very least, new insights into the mechanisms of genetic regulation in bacterial cells, and, very likely, human cells, as well.
2. ONLINE EDUCATION
Teaching the Internet as a Tool in Microbiology Study and Research. Construction of a Website.
I have constructed a teaching module for my Freshman Microbiology Course designed to teach the use of the internet as a tool in Microbiology Education and Research. This work was presented at ASM Meetings, Division of Microbiology Education (30-33) and at the Virtual Conference on Computers in University Biology Education (32). This work resulted in the development of a website (http://www.nycpm.edu/leifer) (24, 29, 37, and 38).
Teaching Online to an International Audience
I have become part of an organization called Internet Biologists. One of their activities is to present courses (28) on the use of the internet for professional biology researchers. I gave lectures to an international audience of molecular biologists in real time via MOO technology (on organizing internet searches (25-26) and on a virtual Microbiology laboratory, see below). This work was presented at a meeting of the International Association of Medical Science Educators (40).
Construction of a Virtual Microbiology Laboratory
Using the virtual biology research center BioMOO, and having taught myself the MOO object-oriented programming language, I constructed a virtual microbiology laboratory, where distance learning can take place in a simulated environment, with the professor present and communicating (23,27).
Online Research Collaboration
Building on this experience, I have published on Research Collaboration via MOO (31, 39).
Future Plans
I plan to continue in developing these interests-to expand the course teaching and website development, online teaching and research collaboration.
3. DIGITAL PATHOLOGY
Design and Use of a Wiki in an Undergraduate Medical Pathology Laboratory Course.
I have been teaching the Pathology Laboratory course at the New York College of Podiatric Medicine since 1982. It is a seventeen-week course, covering Basic and Systemic Pathology. Initially, we worked with a set of glass slides. Since 2011, via Olympus, we converted to Virtual Microscopy/Digital Pathology.
As part of the classroom activities, I constructed a Wiki to aid the students in their studies (42,44,45,46).
Construction of a Virtual Path Lab website to enhance residency training
I put together a website, in line with the numerous Virtual Patient sites, containing clinical scenarios with alternate endings, to reach a diagnosis. In my site, the environment is a pathology diagnostic lab, featuring virtual slides (via web connections) so that the resident can try his hand at scanning the slide, finding the right area and making his diagnosis. Here, too, there is an engaging story-line to enhance the experience, along with links to the literature and other helpful features (47,48).
The use of 3D paper printing to enhance pathology education and research.
I developed a system of representing a tissue sample in multiple sections in a three-dimensional representation, to enhance visualization of the dimensions and localization of the pathology, using a unique 3D paper printing methodology (43).
Future plans
I have an interest in the use of Telepathology in urinalysis. Another idea is the use of neural network analysis for slide study. Also, more work on 3D representation of tissue samples.
