Abstract
Hyperscanning studies have begun to unravel the brain mechanisms underlying social interaction, indicating a functional role for interpersonal neural synchronization (INS), yet the mechanisms that drive INS are poorly understood. The current study, thus, addresses whether INS is functionally-distinct from synchrony in other systems - specifically the autonomic nervous system and motor behavior. To test this, we used concurrent functional near-infrared spectroscopy - electrocardiography recordings, while N = 34 mother-child and stranger-child dyads engaged in cooperative and competitive tasks. Only in the neural domain was a higher synchrony for mother-child compared to stranger-child dyads observed. Further, autonomic nervous system and neural synchrony were positively related during competition but not during cooperation. These results suggest that synchrony in different behavioral and biological systems may reflect distinct processes. Furthermore, they show that increased mother-child INS is unlikely to be explained solely by shared arousal and behavioral similarities, supporting recent theories that postulate that INS is higher in close relationships.

Abstract
Urethral diverticula have proved to be a common cause of recurrent urinary tract infections in female subjects. Positive-pressure urethrography, mostly performed by means of double-balloon catheters, has hitherto been regarded as the method of choice for their detection. Unfortunately, the few existing commercial catheter devices have certain disadvantages, which have led to a lack of acceptance of this important technique and restricted its use. We therefore present an improved tool for positive-pressure urethrography and a synopsis of diagnostic visualization procedures for urethral diverticula in women.

Abstract
The influence of bepridil on steady-state serum digoxin concentrations (SDCs) and the pharmacodynamic actions of both drugs were tested in 48 healthy subjects in a randomized, double-blind study. Subjects were assigned to one of two groups of 24 subjects each: One group received placebo 1, while the other received digoxin, 0.375 mg/day, loaded with doubled doses on days 1 and 2, for 14 days. After 7 days the groups were subdivided into four groups of 12 subjects each and received concurrent dosing of digoxin with either placebo 2 or bepridil, 300 mg/day, loaded with 900 mg on day 8. Mean (+/- SD) SDCs rose during concurrent bepridil dosing from 0.93 +/- 0.22 to 1.25 +/- 0.25 ng/ml (P less than 0.001). Noninvasive cardiovascular parameters from ECG, systolic time intervals, and electrical impedance cardiography were not influenced by the placebos. Digoxin and bepridil reduced heart rate and prolonged the PQ interval because of negative chronotropic and dromotropic properties. Positive inotropism from digoxin shortened the corrected electromechanical systole (QS2c) and the preejection period and increased impedance cardiography [(dZ/dt)/RZ index]; the opposite effects occurred after bepridil, indicating negative inotropism. The QT interval corrected for heart rate (QTc) showed a similar pattern of changes, as did QS2c for each drug. Concurrent dosing of both drugs resulted in an addition of their chronotropic effects, whereas the dromotropic effects of each drug alone was not intensified. The strengthened digoxin effect from the increased SDC diminished the negative inotropic effect of bepridil. Overall, drug coadministration resulted in a nearly unchanged digoxin-induced positive inotropism.(ABSTRACT TRUNCATED AT 250 WORDS)
