Marine microalgae constitute a natural source of a variety of drugs for pharmaceutical, food and cosmetic applications-which encompass carotenoids, among others. A growing body of experimental evidence has confirmed that these compounds can play important roles in prevention (and even treatment) of human diseases and health conditions, e.g., cancer, cardiovascular problems, atherosclerosis, rhe...

The practice of setting quantum fields as sources for classical general relativity is examined. Several conceptual problems are identified which invalidate apparently innocuous equations. Alternative ways to links classical general relativity with quantum theory using Bohm’s theory are proposed. PACS numbers: 12.90.+b, 03.65.Ta, 04.20.Cv Submitted to: Class. Quantum Grav. Quantum fields as grav...

The objectives of this work were: (1) To determine whether repeated exposures to small doses from a commercial sun bed (Wolff Solarium Super Plus 100 W) over 5 weeks gave less vitamin D than repeated exposures to twice as large, but still nonerythemogenic, doses. (2) To investigate whether the contribution to the vitamin D status from such sessions of exposures was dependent on the baseline sta...

To discuss amino acids as energy sources seems at first sight a rather bizarre notion. It is not that there are any particular difficulties in accepting the concept, but rather that it seems a somewhat extravagant or whimsical idea, rather like a discussion of caviar as a pig food. Nevertheless, the topic does merit discussion. For some animals protein regularly predominates in the diet. In adu...

Since the 1990s, the scope of research evaluations becomes broader as the societal products (outputs), societal use (societal references), and societal benefits (changes in society) of research come into scope. Society can reap the benefits of successful research studies only if the results are converted into marketable and consumable products (e.g., medicaments, diagnostic tools, machines, and...

The notion that fatty acids (FA) can act as a significant source of energy for higher animals has been so much a part of our understanding of metabolism that just to express it seems platitudinous. We can however sharpen the notion a little by suggesting that this is the major function of FA. While protein and carbohydrates can and do act as energy sources they have other quantitatively importa...

The Navrongo Community Health and Family Planning Project is a quasi-experimental study designed to test the hypothesis that introducing health and family planning services in a traditional African societal setting will introduce reproductive change. This article presents the impact of the initial three years of project exposure on contraceptive knowledge, awareness of supply sources, reproduct...
