متن کاملDo Astrocytes Respond to Dopamine?
Astrocytes are now recognised as important contributors to synaptic transmission control. Dopamine is a key neuromodulator in the mammalian brain and establishing the potential extent of its actions involving astrocytes is vital to our overall understanding of brain function. Astrocyte membranes can express receptors for dopamine, as well as dopamine transporters, but the full effects of dopami...
متن کاملTo respond or not to respond to hydroxyurea in thalassemia: a matter of stress adaptation?
I n hereditary hemoglobinopathies, such as sickle cell anemia (SCA) and beta-thalassemia (BT), the absolute level of fetal hemoglobin (HbF) production is a critical predictor of severity. High HbF is protective against sickling and vaso-occlusive complications in SCA, and high levels of gamma-globin (the non-alpha globin component of HbF) compensate for beta-globin deficiency in BT, reducing th...
متن کاملThe authors respond to Egilman.
Dr. Egilman highlights the need for testing of chemicals prior to their use by workers and consumption by the public [Egilman, 2014]. We agree that the demonstrated toxicity of diacetyl illustrates the need for testing and great vigilance regarding diacetyl substitutes, other flavoring chemicals, and chemicals involved in flavor manufacture, and that such an approach would better ensure the saf...
متن کاملHow roots respond to gravity.
Current knowledge about the mechanisms of plant root response to gravity is reviewed. The roles of the columella region and amyloplasts in the root cap are examined. Results of experiments related to gravistimulation in corn roots with and without root caps are explained. The role of auxin, abscisic acid, and calcium also are examined.
