The relaxation effects of forskolin and methylxanthines on noradrenaline (NA)-induced contractions were investigated by measuring isotonic contraction and intracellular calcium concentration ([Ca2+]i) in the epididymal side of guinea-pig vas deferens. NA (100 microM) and high K+ (55 mM) induced a biphasic contraction; fast, transient (phasic) and slow,(More)
The contractile responses to various concentrations of noradrenaline (NA), adenosine triphosphate (ATP), acetylcholine (ACh) and excess external K+ in the epididymal, middle and prostatic portions of the guinea-pig vas deferens were investigated by measuring the isotonic contraction, and the intracellular Ca2+ concentration ([Ca2+]i) using fura-2(More)
Calcium-activated potassium channels were the channels most frequently observed in primary cultured normal mammary cell and in the established mammary tumor cell, MMT060562. In both cells, single-channel and whole-cell clamp recordings sometimes showed slow oscillations of the Ca2(+)-gated K+ current. The characteristics of the Ca2(+)-activated K+ channels(More)
The properties of Ca2+-activated K+ channels in mouse mammary epithelial cells in primary culture were studied by the patch-clamp technique. In cell-attached patches, spontaneous channel openings were sometimes observed; the slope conductance of the currents was about 12 pS at negative membrane potentials with a physiological solution (152 mM Na+, 5.4 mM(More)
Ground reaction force during walking was measured and analyzed in 58 patients who had been hemiplegic for more than 6 months. Utilizing the impulse (area between a component curve and the baseline) as an assessment value, several parameters were selected to represent the characteristics of each component curve (vertical, fore-aft and lateral) of the ground(More)
Non-gamma-Aminobutyric acid (GABA)-mediated effects of benzodiazepines (BZs) have not been widely investigated. However, there is significant evidence in the literature to suggest that several experimental and clinical observations are inconsistent with the commonly accepted GABAergic mechanisms of action for these drugs. The purpose of the present study(More)
We studied the effect of spider toxin (JSTX)--specific blocker of glutamate receptor--on giant synapse of the squid stellate ganglion. JSTX irreversibly blocked the excitatory postsynaptic potential (EPSP) without affecting the presynaptic action potential or the antidromic action potential. L-glutamate depolarized the postsynaptic membrane and suppressed(More)
Equations describing the motion of the dinoflagellate Prorocentrum minimum, which has both a longitudinal and a transverse flagellum, were formulated and examined using numerical calculations based on hydrodynamic resistive force theory. The calculations revealed that each flagellum has its own function in cell locomotion. The transverse flagellum works as(More)
We used computerized tomography to evaluate the position of the tibial tubercle and to determine if the tibial tubercle is positioned more laterally in female patients with patellofemoral pain. We also wanted to determine the relationship of the tibial tubercle to tibial external rotation and patellar tilt. Sixty female patients and 19 healthy female(More)
BACKGROUND Factors associated with liver stiffness (LS) are unknown and normal reference values for LS have not been established. Individuals at high risk for alcoholic (ALD) and non-alcoholic fatty (NAFLD) liver disease need to be non-invasively discriminated during routine health checks. Factors related to LS measured using a FibroScan and normal(More)
