Gardening 101: Japanese Maple Trees. Elegant, colorful Japanese Maple trees are so easy to grow they deserve a special place in every garden. Both graceful and versatile, Japanese maple trees (Acer palmatum) are the chameleons of the plant world. Some leaf out in brilliant reds in spring, change to green by summer, and finish the fall in yellows and oranges. Others start red and stay red till their leaves drop in autumn, revealing their sculptural forms.
Glycogen storage disease. Glycogen storage disease (GSD, also glycogenosis and dextrinosis) is the result of defects in the processing of glycogen synthesis or breakdown within muscles, liver, and other cell types. GSD has two classes of cause: genetic and acquired.
Glycogen is a polysaccharide that is the principal storage form of glucose (Glc) in animal and human cells. Glycogen is found in the form of granules in the cytosol in many cell types. Hepatocytes (liver cells) have the highest concentration of it - up to 8% of the fresh weight in well fed state, or 100-120 g in an adult. In the muscles, glycogen is found in a much lower concentration (1% of the muscle mass), but the total amount exceeds that in liver. Small amounts of glycogen are found in the kidneys, and even smaller amounts in certain glial cells in the brain and white blood cells. Glycogen plays an important role in the glucose cycle.
