Teaching physiology and the World Wide Web: electrochemistry and electrophysiology on the Internet

The American Journal of Physiology
T M DwyerT G Coleman

Abstract

Students seek active learning experiences that can rapidly impart relevant information in the most convenient way possible. Computer-assisted education can now use the resources of the World Wide Web to convey the important characteristics of events as elemental as the physical properties of osmotically active particles in the cell and as complex as the nerve action potential or the integrative behavior of the intact organism. We have designed laboratory exercises that introduce first-year medical students to membrane and action potentials, as well as the more complex example of integrative physiology, using the dynamic properties of computer simulations. Two specific examples are presented. The first presents the physical laws that apply to osmotic, chemical, and electrical gradients, leading to the development of the concept of membrane potentials; this module concludes with the simulation of the ability of the sodium-potassium pump to establish chemical gradients and maintain cell volume. The second module simulates the action potential according to the Hodgkin-Huxley model, illustrating the concepts of threshold, inactivation, refractory period, and accommodation. Students can access these resources during the scheduled lab...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
