What ignites optical jets ? ∗ †
The properties of radio galaxies and quasars with and without optical or X-ray jets are compared. The majority of jets from which high-frequency emission has been detected so far (13 with optical emission, 11 with X-rays, 13 with both) are associated with the most powerful radio sources at any given redshift. It is found that optical/X-ray jet sources are more strongly beamed than the average p...
متن کاملCD40L-CD40 fuel ignites obesity.
Obesity and its metabolic complications like insulin resistance and type II diabetes with their continuously increasing morbidity and mortality represent a challenge for global health care (1). Yet, detailed mechanistic understanding of the pathogenesis of obesity and its metabolic complications as well as effective treatment options are still lacking. Inflammation is considered to have a pivot...
متن کاملAgglomeration Economies: The Spark That Ignites a City?
www.phil.frb.org Business Review Q4 2003 7 www.phil.frb.org employment in the U.S. is located in metropolitan areas, and these areas account for 24 percent of the total land area of the country. Why is employment so heavily concentrated in selected areas of the country? Economists think that spatial concentration of employment (or, more generally, economic activity) develops for two very differ...
متن کاملUCP1-independent thermogenesis in white adipose tissue of cold-acclimated Ucp1-/- mice.
Apart from UCP1-based nonshivering thermogenesis in brown adipocytes, the identity of thermogenic mechanisms that can be activated to reduce a positive energy balance is largely unknown. To identify potentially useful mechanisms, we have analyzed physiological and molecular mechanisms that enable mice, genetically deficient in UCP1 and sensitive to acute exposure to the cold at 4 degrees C, to ...
متن کاملWhen pigs fly, UCP1 makes heat
Brown and beige adipose tissue may represent important therapeutic targets for the treatment of diabetes and obesity as these organs dissipate nutrient energy as heat through the thermogenic uncoupling protein 1 (UCP1). While mice are commonly used to mimic the potential effects of brown/beige adipose tissue that may act in human metabolism, new animal models are edging into the market for tran...
