The brain-belly connection: Scientists find key genetic triggers in weight-regulating brain cells
The little voice inside your head that tells you to eat, or stop eating, isn’t a little voice — it’s actually a cluster of about 10,000 specialized brain cells. And now, an international team of scientists has found tiny triggers inside those cells that give rise to this “voice,” and keep it speaking throughout life. […]
High-fat diet, obesity during pregnancy harms stem cells in developing fetus
Physician-scientists at OHSU Doernbecher Children’s Hospital reveal a high-fat diet and obesity during pregnancy compromise the blood-forming, or hematopoietic, stem cell system in the fetal liver responsible for creating and sustaining lifelong blood and immune system function. The life-long burden of a western-style diet on the heart and circulatory system have long been appreciated. However, […]
Immune cells in brain respond to fat in diet, causing mice to eat
Immune cells perform a previously unsuspected role in the brain that may contribute to obesity, according to a new study by UC San Francisco researchers. When the researchers fed mice a diet high in saturated milk fats, microglia, a type of immune cell, underwent a population explosion in the brain region called the hypothalamus, which […]
Cancer cells adapt energy needs to spread illness to other organs
Want to understand why cancer cells metastasize? Think of Sparta. Ancient Greek warriors were fed a special diet that better prepared them for the demands of battle on distant fields. Cancer cells that metastasize may do the same thing according to a new study revealing previously unknown differences between cancer cells that continue to grow […]
Using math to analyze movement of cells, organisms, disease
Recent SIAM research has married math with science. The information below outlines three of those articles. Traveling waves model tumor invasion Cell migration, which is involved in wound healing, cancer and tumor growth, and embryonic growth and development, has been a topic of interest to mathematicians and biologists for decades. In a paper published recently […]
Declare War On Fat Cells, Pick Battles Strategically
Skip image[1] Fitness Columnist Dominic Lucibello by Dominic Lucibello | June 05, 2013 Fat loss is war. The fight requires a strategic plan and a commitment to stick to the plan no matter how long the battle lasts. Exercise, nutrition, hormones, digestion, sleep, hydration, supplementation and stress levels all have an effect on fat loss. […]
