Figure Lengend Snippet: (a) A customized moving blocker system mounted on an Elekta Synergy XVI system. Components of the moving blocker system are labeled as (A) a lead-strip blocker (3.2 mm lead strip width and 3.2 mm interspace); (B) a linear motion guide actuator (KR20, THK); (C) a bipolar stepper motor with controller(PD1141, TRINAMIC). (b) Three customized blockers, lead strips were 3.2 mm in thickness and 20 pixels (3.2 mm) in width. Interspace was 20 pixels (3.2 mm) for A1, 40 pixels (6.4 mm) for A2 and 60 pixels (9.6 mm) for A3.

Article Snippet: Considering speed variation, direction changes and system stability, the linear motion speed of the blocker was set as 7, 13.2, and 20.2 mm/s, which corresponded to a speed of 8, 15 or 23 pixels per projection at the detector plane in our experiment. fig ft0 fig mode=article f1 fig/graphic|fig/alternatives/graphic mode="anchored" m1 Open in a separate window Fig. 3 caption a7 (a) A customized moving blocker system mounted on an Elekta Synergy XVI system.

Figure Lengend Snippet: Effects of KCNQ channel blockers on the currents in type I cells at different ages. A, The KCNQ blocker linopirdine (10 μm) reversibly reduced gmax of the K current in a P6 type I cell by 43% without affecting V1/2 (V1/2, S, and gmax values: Control, −29 mV, 7.1 mV, 9.1 nS; Linopirdine-sensitive, −29 mV, 6.1 mV, 4.2 nS; Linopirdine-insensitive, −27 mV, 9.0 mV, 5.1 nS). B, The KCNQ blocker XE991 (10 μm) blocked most of the current in a P13 type I hair cell (control V1/2, S, gmax values, −58 mV, 8.8 mV, 47 nS). The residual current appears to be leak, in that the tail current activation curve was completely blocked. We do not show the activation curves because short voltage steps do not produce an accurate activation curve (Wong et al., 2004). C, In a P16 type I cell with a large negative conductance, linopirdine (10 μm) blocked 23% of the current evoked at the onset of steps from the holding potential, −69 mV (23% of gHP).

Article Snippet: We applied agents that are reputedly KCNQ or erg specific in the first and third postnatal weeks, using concentrations that have been effective at separating KCNQ and erg conductances in neurons: 10 μ m of the KCNQ blockers linopirdine and XE991 and of the erg blockers E-4031 or WAY-123,398 ( Wang et al., 1998 ; Meves et al., 1999 ; Selyanko et al., 1999 ; Higashida et al., 2000 ; Brown et al., 2002 ). and show examples of KCNQ and erg blocker effects, respectively, at different ages. summarizes blocker effects as a function of age. fig ft0 fig mode=article f1 fig/graphic|fig/alternatives/graphic mode="anchored" m1 Open in a separate window Figure 6. caption a7 Effects of KCNQ channel blockers on the currents in type I cells at different ages.

Figure Lengend Snippet: Whole-cell perforated-patch recording from calyces and attached afferent stalks revealed large K+ and Na+ conductances. A, Photomicrograph showing a calyx and attached afferent stalk isolated from its hair cell; P21. B, Whole-cell currents recorded from the calyx in A deactivated during hyperpolarizations (arrow). A transient inward current, presumably through an Na+ conductance, gNa, was evoked by steps from potentials negative to −79 mV to the tail potential of −39 mV. XE991 at 1 μm blocked most of the outward current (see difference current). Bottom, Tail current activation curves fitted with Boltzmann functions. V1/2, S, gmax values are as follows: control current, −52 mV, 15.9 mV, 30 nS; XE991-sensitive component, −51 mV, 14.6 mV, 27 nS; XE991-insensitive component, −64 mV, 5 mV, 4 nS. C, Whole-cell perforated-patch recording from a different calyx and attached stalk, isolated from a crista; P19. This afferent had a very large current that activated positive to −100 mV, reversed at EK (−85 mV), and inactivated strongly for steps positive to −70 mV.
