In 1990, its primary mission over, Voyager 1 was instructed to point its camera at Earth, or the Pale Blue Dot, 6 billion kilometers away. VOYAGER 1 has been beaming data to Earth since 1977. But members of mission control at NASA's Jet Propulsion Laboratory (JPL), in Pasadena, California, are as excited as ever.
Cause of Elevated A1c Levels. The higher your blood sugar levels and the longer your blood sugar remains high, the more excess sugar is present in the blood and the more opportunities this excess sugar has to bond to hemoglobin.
Causes of High Levels. As noted by the National Institutes of Health, DHEA is at its highest in early adulthood, but sometimes higher-than-normal levels can occur regardless of age. Adrenal disease is the main cause of high DHEA levels, according to the American Association for Clinical Chemistry. Adrenal tumors -- either benign or cancerous growths that attach themselves to the adrenal glands -- may cause an overproduction of the DHEA hormone. Adrenal hyperplasia, a swelling of the gland, can also cause high levels of DHEA.
