Conclusions: In more than a third of patients with posterior urethral valves renal function reserve is completely depleted at presentation. Decreased or absent renal function reserve may be used as an early indicator of long-term renal deterioration.”
“We investigated the relationship between short-latency and long-latency somatosensory-evoked potentials (SEPs) relating to voluntary movement. In general, the amplitudes of short-latency components in SEPs are attenuated during movement,

Saracatinib in vivo whereas those of long-latency are enhanced, and this phenomenon is termed ‘gating effects’. This study aimed to examine the relationship of changes in amplitude between short-latency and long-latency SEPs. SEPs were recorded from 11 participants at Fz, Cz, Pz, and C4′ by stimulating the left median nerve. Two tasks were conducted; Control and Movement. In Control, the participant was asked to relax with no specific task. In Movement, the participant was encouraged to continue a rapid drumming motion of all fingers of the left hand at a self-paced rate. The amplitudes of short-latency SEPs, the P25 at C4′ and N30 at Fz, were significantly

smaller in the Movement than Control condition. By contrast, the amplitudes of long-latency SEPs, the N140 at Fz, Cz, and Pz were significantly larger in Adriamycin Movement than Control condition. Moreover, a significant positive correlation was observed in the rate of amplitude change between the frontal N30 and vertex N140, indicating that for the participants with a frontal N30 of smaller amplitude during Movement, the amplitude of the vertex N140 was smaller. We inferred that the neural activities in movement-related cortices affected the during sources for the frontal N30 and vertex N140 in the same neuronal network simultaneously.

“Studies of the salivary cortisol awakening response (CAR) may be confounded by delays between waking in the morning and obtaining the ‘waking’ salivary

sample. We used wrist actigraphy to provide objective information about waking time, and studied the influence of delays in taking the waking sample on the CAR. Eighty-three men and women (mean age 61.30 years) who were referred to hospital with suspected coronary artery disease were studied. Saliva samples were obtained on waking and 15 and 30 min later. The mean interval between waking defined by actigraphy and reported waking time was 6.12 +/- (S.D.) 14.8 min, with 55.4% having no delay. The waking saliva sample was obtained an average 5.78 +/- 15.0 min after self-reported waking, and 12.24 +/- 20.3 min after objective waking. The waking cortisol value was significantly higher in participants who had a delay between waking and sampling > 15 min (mean 14.46 +/- 6.34 nmol/l) than in those with zero (mean 10.45 +/- 6.41 nmol/l) or 1-15 min delays (mean 11.51 +/- 5.99 nmol/l, p = 0.043).
