Frequency-dependent characteristics of nerve-mediated ATP and acetylcholine release from detrusor smooth muscle.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

findingsWhat is the central question of this study? Is the frequency dependence of co-transmitter release from postganglionic nerve fibres different for each transmitter? What is the main finding and its importance? Release of co-transmitters from the parasympathetic supply to detrusor smooth muscle can be independently regulated. This offers a targeted drug model to reduce selectively the release of transmitter associated with human pathologies (ATP) and may also be applicable to other smooth muscle-based disorders of visceral tissues. ABSTRACT: Nerve-mediated contractions of detrusor smooth muscle are mediated by acetylcholine (ACh) and ATP release in most animals. However, with the normal human bladder, only ACh is a functional transmitter, but in benign pathologies such as overactive bladder (OAB), ATP re-emerges as a secondary transmitter. The selective regulation of ATP release offers a therapeutic approach to manage OAB, in contrast to current primary strategies that target ACh actions. However, the release characteristics of nerve-mediated ACh and ATP are poorly defined and this study aimed to measure the frequency dependence of ACh and ATP release and determine if selective regulation of ATP or ACh was possible. Experiments were carried out in vitro with mouse detrusor with nerve-mediated ATP and ACh release measured simultaneously with tension recording. ATP was released in two frequency-dependent components, both at lower frequencies (mid-range 0.4 and 5.5 Hz stimulation) compared to a single compartment release of ACh at 14 Hz. Intervention with the phosphodiesterase type-5 inhibitor sildenafil attenuated ATP release, equally from both components, but had no effect on ACh release. These data demonstrate that nerve-mediated ACh and ATP release characteristics are distinct and may be separately manipulated. This offers a potential targeted drug model to manage benign lower urinary tract conditions such as OAB.
