The faculty of biochemistry established an integrated teaching strategy for biotechnology specialty students, by intermeshing the case-study method, web-assistant teaching, and improved lecture format with a brief content and multimedia courseware. Teaching practice showed that the integrated teaching strategy could retain the best features of…

Many high school biology courses address mainly the molecular and cellular basis of life. The complexity that underlies the most essential processes is often difficult for the students to understand; possibly, in part, because of the inability to see and explore them. Six simple practical experiments on purine catabolism as a part of a…

Matrix metalloproteinases (MMPs) are a family of extracellularly acting proteolytic enzymes with well-recognized roles in plasticity and remodeling of synaptic circuits during brain development and following brain injury. However, it is now becoming increasingly apparent that MMPs also function in normal, nonpathological synaptic plasticity of the…

The CARBOHYDECK card game is designed to motivate undergraduate chemistry or biochemistry nonmajors to learn about isomerism of monosaccharides.

This study investigating the effectiveness of Calibrated Peer Review (CPR )[TM] in a senior-level biochemistry class had three purposes: to (a) compare the CPR process for feedback with TA-generated feedback in improving students' ability to write scientific abstracts; (b) compare CPR results for males and females; and (c) observe whether CPR…

Undergraduate research in the biochemistry, cell, and molecular biology program at Drake University uses apprenticeship, cooperative-style learning, and peer mentoring in a cross-disciplinary and cross-community educational program. We call it the one-room schoolhouse approach to teaching undergraduate research. This approach is cost effective,…

This study examined interrelationships among children's cortisol reactivity and their psychological reactivity to interparental conflict in a sample of 208 first graders (mean age = 6.6 years). Assessments of children's psychological reactivity to conflict distinguished among their distress, hostile, and involvement responses across multiple…

Genome science, including topics such as gene recombination, cloning, genetic tests, and gene therapy, is now an established part of our daily lives; thus we need to learn genome science to better equip ourselves for the present day. Learning from topics directly related to the human has been suggested to be more effective than learning from…

Can genetic evolution be controlled by man in a manner which does not violate a civilized, humane, and democratic ethos? The genetics of health and illhealth and of normal variation are discussed with respect to this question. (PEB)

Examined were medical records of 265 hyperkinetic children (7-9 years old). Clinical blood chemistries, hematology, and 5-hour glucose tolerance test (GTT) results indicated that hematocrit levels were low in 27% of the Ss, eosinophil levels were abnormally high in 86% of the Ss, and GTT results were abnormal in a maority of Ss.

Biorhythm comes from the Greek words for life and regulated beat. The science of biorhythm is concerned with the rhythmic cycles of physical, emotional, and intellectual life. These cycles have lengths of 23, 28, and 33 days respectively. During the first half of each cycle, energy is high. During the low period, second phase abilities, feelings,…

The nature of the work performed by biologists and biochemists is described in general terms, and for the subcategories such as agronomists, pharmacologists and entomologists. The types of employment opportunities, the necessary training the employment outlook and typical salaries and working conditions are described. Addresses for requesting…

Information on the centromere, or kinetochore, varies from textbook to textbook. This article reviews and reconsiders how this body is defined. (BB)
