Presents an activity in which students observe gelatin samples treated with substances that may or may not have an enzymatic effect on the protein on the gelatin. (WRM)

Discusses how to make the best choices for converting journals retrospectively to digital and online format. Results indicated that differences exist between the two disciplines examined--ecology and biochemistry--in the ages of literature used. Discusses possible screening methods before doing an extensive citation analysis of a discipline's…

Describes a computer software program that simulates each step of the glycolytic enzyme pathway. Serves as a means of providing interactive learning for undergraduate biochemistry students with the aim of better preparing them for laboratory work. (Author/CCM)

Describes the experiences of a medical school faculty who have been offering for more than 10 years a two-course series in the biochemistry of human disease to undergraduate students majoring in biochemistry, biology, or chemistry. Recommends the teaching of specialized, advanced courses to undergraduate, pre-professional students. (DDR)

Presents a method aimed at developing the ability of students to handle information, participate in group discussions, and accept and give constructive criticism. Involves synthesizing information in poster handouts and taking part in a student-centered assessment. Evaluates through an objective scoring strategy that leads to the identification of…

An extremely simple, inexpensive, and safe method is presented, which emulates nucleic acids isolation and electrophoretic analysis as performed in a research environment, in the context of a secondary school hands-on activity. The protocol is amenable to an interdisciplinary approach, taking into consideration the electrical and chemical…

This case study involves the biochemical analysis of the components of commonly available energy drinks, which many students purchase at fairly high prices. Students research the ingredients in each product and their physiological role in the human body, and then attempt to match what they learn with the product manufacturers' marketing claims.…

To ensure the safety of school-aged children and adolescents, school counselors must not ignore or deny the public health threat of bioterrorism (Henderson, 1998). Rather, school counselors must be prepared with knowledge about bioterrorism and intervention skills. Bioterrorism within the United States is a continuing threat. Because children and…

In this study the photoinhibition of photosystems (PS) I and II caused by exposure to high intensity light in oat ("Avena sativa," var Prevision) is measured by the emission of chlorophyll fluorescence in intact leaves adapted to darkness. The maximal quantum yield of PS II was lower in plants grown under high light intensity than in plants grown…

Despite their purported neuroanatomic and functional isolation, empirical evidence suggests that sometimes conscious explicit processes can influence implicit motor skill learning. Our goal was to determine if the provision of explicit information affected implicit motor-sequence learning after damage to the basal ganglia. Individuals with stroke…

Studies of gene expression following fear conditioning have demonstrated that the inducible transcription factor, "egr-1," is increased in the lateral nucleus of the amygdala shortly following fear conditioning. These studies suggest that "egr-1" and its protein product Egr-1 in the amygdala are important for learning and memory of fear. To…

The enzyme orotidine-5'-monophosphate decarboxylase is an attractive choice for the central theme of an integrated, research-based biochemistry laboratory course. A series of laboratory exercises common to most instructional laboratories, including enzyme assays, protein purification, enzymatic characterization, elementary kinetics, and…

This article outlines an undergraduate course focusing on supramolecular membrane protein complexes involved in the molecular pathogenesis of neuromuscular disorders. The emphasis of this course is to introduce students to the key elements involved in the ion regulation and membrane stabilization during muscle contraction and the role of these…

The working drafts of the human genome, announced in February 2001, have clearly provided a breakthrough in biochemistry and molecular biology research. The scientific data also provide an opportunity to vary a typical approach to teaching. Advanced graduate students at our university can elect to take a course in molecular genetics. The human…

Professors often expect students to have the skills that are necessary to participate in discussions. Students, on the other hand, have been trained to glean information from the lecture format; their prior experiences in discussions are likely to be limited to personal opinions on topics such as stem-cell research or evolution. Sudden changes in…
