The use of virtual microscopy and a wiki in pathology education: Tracking student use, involvement, and response.

Background: The pathology laboratory course at the New York College of Podiatric Medicine involves the use of Virtual Microscopy. The students can scan the whole slide, section by section, and zoom in or out.

Methods: Using the advantages of digital pathology, the students can, in addition, access the slide collections from other medical schools and put up normal histology (control) slides side-by-side with the pathology.

Pediatric resources on the Internet.

This article introduces the podiatric physician interested in pediatrics to the resources available on the Internet. It surveys search engines, gateway sites on the World Wide Web leading to a wealth of pediatric information and services, and features such as electronic mail, news-groups, and Gopher sites. Examples illustrate how such resources can be helpful to the practicing podiatrist.

Independent studies program in the basic sciences. A curricular innovation.

The Independent Studies Program was initiated at the New York College of Podiatric Medicine during the early months of 1987, and it has achieved continued success and acceptance from the administration, faculty, and students. The program emphasizes competence as the constant within a relatively time-independent framework. This paper presents, in a longitudinal fashion, the Independent Studies Program as a program model that combines criterion-referencing concepts, mastery-based learning combinations, and self-learning strategies.

Putrescine and spermidine sensitivity of lysine decarboxylase in Escherichia coli: evidence for a constitutive enzyme and its mode of regulation.

Cells of Escherichia coli grown under physiological (noninducing) conditions have a low level of lysine decarboxylase activity. This activity differs from the enzyme found in induced cells in its sensitivity to putrescine (33% of control in the presence of 20 mM putrescine). It is also sensitive to spermidine (20% of control in the presence of 6 mM spermidine).

An evaluation of tests using DNA repair-deficient bacteria for predicting genotoxicity and carcinogenicity. A report of the U.S. EPA's Gene-TOX Program.

The detection of DNA-damaging agents by repair-deficient bacterial assays is based on the differential inhibition of growth of repair-proficient and repair-deficient bacterial pairs. The various methodologies used are described and recommendations are made for their improved use. In a survey of the literature through April 1979, 91 of 276 papers evaluated contained usable data, resulting in an analysis of 611 compounds that had been assayed in 1 or more of 55 pairs of repair-proficient and repair-deficient strains.
