SC 217: Topics in Science – Class presentation available.

This class is a collection of short presentations on science topics that are of interest to the general public. It is intended to be in plain English and easily understood, although some scientific principles will be presented.

Monday, June 2: The Dynamics of Sleep. Sleep, a fundamental necessity of animal life, has been the subject of a vast amount of research. Some of the features that will be covered in this talk include jet lag, sleep apnea, circadian rhythm, REM sleep, napping, sleep physiology and multiple hypotheses of why we sleep.

Presenter:  Jerry Florman, retired pharmacist and longtime OLLI Science Committee member, has presented classes on many diverse topics in science, art and philosophy.

Monday, June 9: Cholesterol and You. A gut check may someday soon become a superior way to access cardiovascular health. The stomach compound trimethylamine-N-oxide (TMAO) has been shown to be highly associated with cholesterol distribution in the blood stream and risk for cardiovascular disease. Healthy intestinal bacteria also play an important role, and successful treatment of a debilitating intestinal bacterium has recently been achieved by a non-medical approach sometimes referred to as fecal transplantation. The medical findings involving the role of cholesterol will be discussed with regard to future impact on heart disease, diabetes, and autoimmune diseases.

Presenters:   Vern Roohk, Ph.D. in Physiology and Biochemistry, Postdoc in Bioengineering. He has been a biomedical device consultant for more than 25 years, and currently is sole proprietor of BioCor Scientific, a technical author and an OLLI Science Committee Member.

Barbara Pogosian, M.S., Microbiology, CSULB, California certificated Public Health Microbiologist, and retired Professor of Biology at Golden West College.
