Describes the separation of proteins from bovine serum and egg-white using carboxymethyl cellulose, Vistec C1. Explains the preparative work that is essential before the technique can be employed. (GS)

Describes research which indicates that a number of peptide hormones act directly on the brain to affect learning and behavior. Investigations are currently being conducted to determine if these substances can be used to treat learning disorders or to improve the memories of normal people. (MLH)

Describes the syllabus of a course emphasizing thermodynamics and light, with no calculus prerequisite, but using calculus. Discusses student preparedness and student response to the course. (GH)

Describes the design of ion selective electrodes coupled with immobilized enzymes which operate either continuously or on drop-sized samples. Cites techniques for urea, L-phenylalanine and amygdalin. Micro size electrodes for use in single cells are discussed. (GH)

Presented are case histories of two children, ages 2 and 4 years, with paroxysmal cold hemoglobinuria (PCH, a syndrome characterized by acute intravascular hemoglobin dissolution and hemoglobin in the urine). (Author/CL)

Describes the project at the University of North Carolina Department of Biochemistry to determine whether validated learning materials could be generated by students for the yearly course, and to determine the effects of self-instruction and student authorship upon the class. (Author/PG)

Discusses some important aspects of bioinorganic chemistry, including interactions of organisms with metallic and nonmetallic elements and compounds. Indicates that many environmental problems are created by human exploitation of nature and technologies if studied from a bioinorganic chemical viewpoint. (CC)
