Abstract

Twenty patients without laboratory evidence of cardiac disease who underwent electrophysiological study because of recurrent ventricular tachyarrhythmias.The study population was divided into two groups: group A (20 patients [six males and 14 females] mean age 42.2 +/- 13 years), with idiopathic ventricular tachycardia (VT), and group B (30 controls [10 males and 20 females] mean age 43.6 +/- 16 years). Noninvasive multiparametric analysis of the ventricular repolarization phase was performed on the standard 12-lead electrocardiogram by using a digitizer connected with a computerized system. The intervals JT, heart rate-corrected JT (JTc), JT apex (JTa), heart rate-corrected JTa (JTac), T apex T end (TaTe) and heart rate-corrected TaTe (TaTec) were measured and considered to be representative of the whole depolarization process. QT dispersions (QTeD) and QTc dispersions (QTecD) were calculated to assess the degree of spatial inhomogeneity of action potential duration.Patients in group A had higher JT (272 +/- 36 ms versus 265 +/- 25 ms, P = 0.01), JTc (336 +/- 28 ms versus 318 +/- 18 ms, P = 0.01), JTa (210 +/- 28 ms versus 185 +/- 28 ms, P = 0.001) and JTac (240 +/- 20 ms versus 215 +/- 13 ms, P0.001) values than those of patients in group B, despite shorter TaTe (71 +/- 10 ms versus 90 +/- 18 ms, P0.001) and TaTec (88 +/- 12 ms versus 110 +/- 12 ms, P0.001). Moreover, QTeD and QTecD were significantly longer in group A than in group B (55 +/- 18 ms versus 42 +/- 19 ms [P = 0.01] and 80 +/- 18 ms versus 55 +/- 28 ms [P = 0.001], respectively).Patients with idiopathic VT exhibit inhomogeneous prolongation of ventricular repolarization, due to a considerable increase in the initial part in association with a shorter terminal phase, as well as a greater dispersion of ventricular repolarization.

48. A newTrichoplusia niantennal receptor neuron that responds to attomolar concentrations of a minor pheromone component

Author

Mayer, M. S. and Mankin, R. W.

Abstract

A newly discovered third class of sensillum trichodea on the antenna ofTrichoplusia nicontains an olfactory receptor neuron that responds to (Z)-9-tetradecen-1-ol acetate at 1×10−18M. The threshold of this neuron is 100–1000 times lower than the thresholds of two previously described pheromone-sensitive neurons that detect (Z)-7-dodecen-1-ol acetate and (Z)-7-tetradecen-1-ol acetate. The sensitivity and selectivity of this receptor neuron is evidence that (Z)-9-tetradecen-1-ol acetate may be important for sexual behavior.

50. Interpreting the relationship between pheromone component emission from commercial lures and captures of Helicoverpa zea (Boddie) in bucket and cone traps

Abstract

Male corn earworm moths, Helicoverpa zea (Boddie), were captured in conical Texas pheromone traps (cone traps) and bucket traps baited with four different commercial lures manufactured by three different manufacturers. Because significant numbers were captured in bucket traps baited with some of the lures, and none with others, the volatile emissions from all of the lures were sampled and analyzed by gas chromatographic methods. The numbers of males captured in two types of trap were compared with bait emissions in an endeavor to define a more effective lure for bucket traps. The lure from one manufacturer captured the same numbers of males in both trap types; one captured more inbucket traps than in cone traps, and another captured only a small number in bucket traps. The emission rate of all active compounds fromeach of the different lures was approximately linear for the duration of the assays. A gas-liquid chromatographic peak associated with a third compound, (Z)-9-tetradecenal, which reduces behavioral responses, was observed in the emissions from all lures evaluated. The effectiveness of the Hercon (Emmigsville, PA) lure in capturing males in both types of trap was associated with a lower emission of (Z)-11-hexadecenal, (Z)-9-hexadecenal and (Z)-9-tetradecenal than from the other lures.
