Explains relationships between energy intake and expenditure focusing on the cellular, chemical and neural mechanisms involved in regulation of energy balance. Information is referenced specifically to conditions of obesity. (Physicians may earn continuing education credit by completing an appended test). (ML)

Evaluates the accuracy and usefulness of a simpler rationale for teaching acid-base physiology as compared to more complex approaches frequently taught in physiology courses. Also reviews problems of terminology, giving emphasis to the significant effects that the choice of words can have on students' concepts. (JN)

Contained are five questions related to chemistry and ecology. Satisfactory answers to these five questions are included. (RH)

Topics in this discussion of photorespiration (light-dependent oxygen consumption and carbon dioxide evolution from leaves) include: (1) the biochemistry of photorespiration; (2) ribulose biphosphate carboxylase and glycollate synthesis; (3) metabolism of glycollate; (4) plants lacking photorespiratory systems; and (5) advantages of…

The syllabus for a refresher course on the physiology and biochemistry of receptors (presented at the 1983 American Physiological Society meeting) is provided. Topics considered include receptor regulation, structural/functional aspects of receptors for insulin and insulin-like growth factors, calcium channel inhibitors, and role of lipoprotein…

Provides information to update Institute of Biology's Studies in Biology No. 111, "Microorganisms and Man," by W. C. Noble and Jay Naidoo (Edward Arnold, 1979). Topics include: (1) food poisoning; (2) airborn infections in man; (3) infection in animals and plants; and (4) biodegradation and biosynthesis. (JN)

Diagnostic profiles of 362 male participants in an exercise program were analyzed to determine the biological variables between exercise adherence and symptoms of coronary disease. Findings indicated that individuals with lower metabolic capacity tended to adhere longer, to be less fit, were leaner, and began with more symptoms related to coronary…

Two experiments are described that examined the influence of time-of-day of presentation on immediate and delayed retention and its potential effects on retrieval from long-term memory. Time of presentation was found to influence both immediate and delayed (28 day) retention, but not retrieval from long-term memory. (Author/SJL)

Compared the metabolic and cardiovascular responses of young and older women while performing shallow water exercise (SWE). Overall, SWE elicited metabolic and cardiovascular responses that met American College of Sports Medicine's guidelines for establishing health benefits. Older females self-selected a greater relative exercise intensity during…

The article addresses the neuroimaging, electrophysiological, and postmortem evidence concerning the neurological basis of dyslexia and concludes that inconsistent findings may be related to limitations of investigative technologies. Correlates of reading ability and disability are discussed in a developmental-neuropsychological context.…

Ideas and scientific definitions as reported by 9-12 year olds collected from class discussions, essays, or examination papers over the course of 32 years are presented. Topics include the living body, tracts, metabolism, the senses, the skeleton, the heart, respiratory ailments, genetics, microbiology, and modern medicine. (KR)

The confusion by students on the use of three terms in their writing is discussed. The definitions of catabolite repression, constitutive, and ribosome binding site, given in the glossaries of 10 textbooks, are compared with the use of these terms in students' papers. (KR)

This review evaluates evidence for metabolic etiologies in autism spectrum disorders, as well as for the efficacy of dietary and vitamin treatments. The relationship between gastrointestinal abnormalities and autism spectrum disorders is also considered, and the need for more research on larger populations of individuals with autism is stressed.…

Systems biology, metabolomics, metabolic engineering, and other recent developments in biochemistry suggest that future biochemists will require a detailed familiarity with the compounds and pathways of intermediary metabolism and their biochemical control. The challenge to the biochemistry instructor is the presentation of metabolic pathways in a…
