To fully appreciate genetics, one must understand the link between genotype (DNA sequence) and phenotype (observable characteristics). Advances in high-throughput genomic sequencing technologies and applications, so-called "-omics," have made genetic sequencing readily available across fields in biology from applications in…

Recombinant protein expression and site-directed mutagenesis of target genes have demonstrated an increasing importance in the fields of molecular biology, biochemistry, biotechnology, and medicine. By using the flavodoxin of the model cyanobacterium "Anabaena" sp. PCC 7120 as a laboratory tool, we designed a comprehensive laboratory…

This article provides strategies that are recommended to elementary school teachers to help students in the U.S. understand Islam and its followers. It discusses the importance of cultural and historical studies in making students aware of the value of Islam to its followers. Three strategies described herein are: the concept of similarities, the…

Explains how x-ray doses to patients are measured. Describes how different techniques expose patients to differing amounts of ionizing radiation. Compares these figures with other natural and man-made sources. (Author/MKR)

Describes principles involved in nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI). (MKR)

Very sensitive SQUID (superconducting quantum interference device) detectors are used in the technique known as magnetoencephalography to provide dynamic images of the brain. This can help our fundamental understanding of the way the brain works and may be of particular use in treating disorders such as epilepsy. (Author/MKR)

Explains the Human Genome Project (HGP) and efforts to sequence the human genome. Describes the role of bioinformatics in the project and considers it the genetics Swiss Army Knife, which has many different uses, for use in forensic science, medicine, agriculture, and environmental sciences. Discusses the use of bioinformatics in the high school…

Describes an experience with the use of a radioactive tracer in medicine. Discusses the methodology of how the tracer was used. (CCM)

Describes college level history course entitled "Healers and Persons" for undergraduate medicine students. Topics include Greek medicine and Hippocrates, Galen of Pergamum, Islamic and Roman culture, medieval medicine, the Renaissance, Harvey, Pasteur, Lister, and Mendel. (KC)

Discusses four main types of medical imaging (x-ray, radionuclide, ultrasound, and magnetic resonance) and considers their relative merits. Describes important recent and possible future developments in image processing. (Author/MKR)

Discusses the field of nuclear medicine. (MKR)

The classroom practices discussed in "Effective Second Language Writing" reflect various trends and methodologies; however, the underlying theme in this volume of the Classroom Practice Series is the need for clear and meaningful communication between ESL writers and their readers. While approaches differ, two core beliefs are constant: ESL…

Presents an experiment that provides students with an opportunity to investigate folk medicine and herbal cures and their accompanying claims. Involves isolating some active compounds from plant materials and demonstrating their antibacterial activity. (JRH)

Describes the physics of Doppler ultrasound used in measuring the velocity of blood flow. Discusses medical applications of this technique. (Author/MKR)

Soap bubbles excited using a vibration generator can be used to model the formation of a diatomic molecule because of their analogous properties to atomic orbitals. (Author)
