Initiation of force generation during vascular smooth muscle contraction involves a rise in intracellular calcium ([Ca(2+)]i) and phosphorylation of myosin light chains (MLC).However, reversal of these two processes alone does not account for the force inhibition that occurs during relaxation or inhibition of contraction, implicating that other mec
Wing polymorphism is a powerful model for examining many aspects of adaptation.The wing dimorphic cricket species, Gryllus firmus, consists of a long-winged morph with functional flight muscles that is capable of flight, and two flightless morphs.One (obligately) flightless morph emerges as an adult with vestigial wings and vestigial flight muscles
We show that, contrary to simple predictions, most AGNs show at best only a small increase of lags in the J, H, K, and L bands with increasing wavelength.We suggest that a possible cause of this near simultaneity of the variability from the near-IR to the mid-IR is that the TEA TREE BW hot dust is in a hollow bi-conical outflow of which we only see
