Iodine and the Thyroid
IODINE AND THE THYROID. III THE SPECIFIC ACTION OF IODINE IN ACCELERATING AMPHIBIAN METAMORPHOSIS. BY W. W. SWINGLE. (From the Department of Biology, Princeton University, Princeton.) Downloaded from http://rupress.org/jgp/article-pdf/1/6/593/1189441/593.pdf by guest on 25 September 2021 (Received for publication, May 13, 1919.) In previous studies on the relation of iodine to the thyroid, as de- termined by the effects produced by feeding this substance and its compounds to larval Anurans, 1 the following conclusions were either stated or implied, all of which have a direct bearing on the present experiments. (1) Inorganic iodine and its compounds, iodoform and potassium iodide, greatly accelerate metamorphosis of tadpoles. (2) Animals from which the thyroid gland had been removed at its inception (i.e. 6 ram. larwe), and which under normal conditions never undergo metamorphosis but grow to an abnormal size, quickly transform into frogs when fed iodine. (3) The follicles of the thy- roids of tadpoles on an iodine diet show a greater colloid content than do the glands of normally fed animals. These facts led to the conclusion that iodine is essential for amphibian metamorphosis, that it is the active constituent of the thyroid glands of these ani- mals, and, judging by its action on thyroidless tadpoles, that it exerts its action directly upon the cells and tissues of the organism without the necessity of undergoing transformation in the gland tissue; i.e., that iodine is capable of functioning as the thyroid hor- mone itself within the body, or else is transformed into this hor- mone through the activity of tissue other than that of the thyroid. -
Krill Oil and Astaxanthin
Krill Oil and Astaxanthin Krill are small reddish-color crustaceans, similar to shrimp, that abound in cold Arctic waters. They survive in such cold, frigid temperatures because of their natural anti- freeze, the polyunsaturated fatty acids EPA and DHA. EPA and DHA are bound to molecules called phospholipids (especially phosphatidyl choline) that act to help transport nutrients into cells and change the structure of animal cell membranes. Studies show that these combined fatty acids have better absorption into the cell membranes throughout the body, especially the brain, as compared to other types of fish oils. Although it has less EPA/DHA content than most fish oils, krill oil seems to be almost twice as absorbable. Unlike fish oil, krill oil also contains a very potent antioxidant, astaxanthin, which helps prevent krill oil from oxidizing (turning rancid). Astaxanthin is a red pigment found in different types of algae and phytoplankton. It is astaxanthin that gives salmon and trout their reddish color. It is considered to be one of the most potent natural antioxidants, almost 50 times stronger than beta-carotenes found in fruits and vegetables and 65 times better as an anti-oxidant than vitamin C. Krill oil is composed of 40% phospholipids, 30% EPA and DHA, astaxanthin, vitamin A, vitamin C, various other fatty acids, and flavanoids (anti-oxidant compounds) Human studies indicate krill oil is powerful at decreasing inflammation throughout the body, especially in the brain. It reduces C-reactive protein, a marker for heart disease. Tests indicate it has a powerful anti-inflammatory remedy for rheumatoid as well as osteoarthritis. -

Opposing Effects of Dehydroepiandrosterone And
European Journal of Endocrinology (2000) 143 687±695 ISSN 0804-4643 EXPERIMENTAL STUDY Opposing effects of dehydroepiandrosterone and dexamethasone on the generation of monocyte-derived dendritic cells M O Canning, K Grotenhuis, H J de Wit and H A Drexhage Department of Immunology, Erasmus University Rotterdam, The Netherlands (Correspondence should be addressed to H A Drexhage, Lab Ee 838, Department of Immunology, Erasmus University, PO Box 1738, 3000 DR Rotterdam, The Netherlands; Email: [email protected]) Abstract Background: Dehydroepiandrosterone (DHEA) has been suggested as an immunostimulating steroid hormone, of which the effects on the development of dendritic cells (DC) are unknown. The effects of DHEA often oppose those of the other adrenal glucocorticoid, cortisol. Glucocorticoids (GC) are known to suppress the immune response at different levels and have recently been shown to modulate the development of DC, thereby influencing the initiation of the immune response. Variations in the duration of exposure to, and doses of, GC (particularly dexamethasone (DEX)) however, have resulted in conflicting effects on DC development. Aim: In this study, we describe the effects of a continuous high level of exposure to the adrenal steroid DHEA (1026 M) on the generation of immature DC from monocytes, as well as the effects of the opposing steroid DEX on this development. Results: The continuous presence of DHEA (1026 M) in GM-CSF/IL-4-induced monocyte-derived DC cultures resulted in immature DC with a morphology and functional capabilities similar to those of typical immature DC (T cell stimulation, IL-12/IL-10 production), but with a slightly altered phenotype of increased CD80 and decreased CD43 expression (markers of maturity). -

Heart Health Through Whole Foods
Heart Health Through Whole Foods Certain whole foods in a diet can ultimately provide heart-healthy benefits. The right foods consumed in the right amounts can help lower cholesterol and/or triglycerides. They may also help to reduce risk for heart disease. Even though the benefits of whole foods may be known, too often individuals turn to over-the-counter supplements instead. It is important to discuss all supplements prior to ingestion with your physician. Individuals may not realize that taking some supplements with certain medications may be harmful or that taking too much of a good thing can be bad. The purpose of this session is to educate how to obtain certain nutrients through whole foods rather then through supplements. It must be noted that some individuals may still need supplements in addition to diet. Once again this should be guided by a physician.

Lack of Knowledge on the Use and Benefits of Creatine
Lack of Knowledge on the Use and Benefits of Creatine Discovering the price at which the potential risks outweigh the potential benefits of creatine supplementation for the average college student Tag Words: creatine, supplements, risks, strength, muscle, training, price, cost, muscular hypertrophy Authors: Geoffrey Casimir, Priyanka Gianchandani, Robert Stasiak with Julie M. Fagan, Ph.D Summary The main issue with creatine supplementation is that creatine supplements are not regulated by the FDA and so there is almost no uniformity among products. In addition, the labels are difficult for most individuals to understand, which makes trying to ascertain what people put into their body even more difficult. There is a strong dissociation between people taking supplements and accepting the risks that come along with them. A sample size of 31 individuals were randomly selected to fill out surveys for a research study that examined the association between the perceived risks and the willingness of people to take creatine as a supplement to aid them in their attempt to increase lean body mass. When it came to the negative side effects such as suffering from severe dehydration, kidney and liver damage, heart problems, or dying at a young age, people were not willing to pay as much money. On average, people did not think charging over $15 for a 1 pound container was worth the risks. Video Link Our informational video will be available at: http://youtu.be/teXS5wCWpTo. Introduction Creatine is an organic acid that was discovered by Michel Eugène Chevreul as a component of skeletal muscle in 1832. It provides cells of the body, particularly those in muscle, with energy through the formation of adenosine triphosphate (ATP). -
