Parameter dependence of the system’s eigenvalues (λ). The eigenvalues determined for four values (108, 140, 220, and 300) of the stereociliary number, NS, are represented on the complex plane. The points designated B, C, and C̄ demonstrate the functional dependence of the system on NS; the arrows indicate the progression of eigenvalues with increasing values of this parameter. The angular frequency at the Hopf bifurcation for C and C̄, ±32,000 s−1, corresponds to a characteristic frequency of ∼5 kHz. Point D, which represents the conservation of state probability in the channel-gating cycle, remains at the origin. The conjugate pair A and Ā are independent of NS and also appear stationary. An additional conjugate pair of eigenvalues, those farthest to the left, have been omitted to permit display of the remaining points on an informative scale. The system is characterized by an eighth-degree characteristic polynomial that precludes a closed form for the eigenvalues; numerical evaluation was therefore necessary.

Article Snippet: Roscovitine potently inhibits cyclin-dependent kinases (CDK) and can independently slow the closing of neuronal (CaV2.2) calcium channels.. We were interested if this drug could affect other ion channels similarly.. Using whole cell recordings, we found that roscovitine specifically slows deactivation of all CaV2 channels (N, P/Q and R) by binding to the open state.

Article Snippet: Type 1 diabetic subjects have decreased epinephrine responses to hypoglycemia that may be counterbalanced by increased b-adrenergic sensitivity.. The goal of this study was to determine whether type 1 diabetic subjects have increased metabolic response to epinephrine and to determine the effect of antecedent hypoglycemia on these responses.. Muscular glucose uptake across the forearm (forearm glucose uptake, Fick principle) and lipolysis (free fatty acid and glycerol levels) were studied before and during a 4-hour euglycemic, hyperinsulinemic (40 mU d m 2 d min ) clamp with epinephrine infusion (0.015 lg d kg 1 d min ) over 3 hours.
