There was no clinical advantage in combining conventional and modified ultrafiltration. Because clinical outcomes were similar across groups, relative risks of the ultrafiltration strategies may influence choice.

Interventions for helping people recognise early signs of recurrence in bipolar disorder.

We present photometry and spectroscopy of the soft x-ray transient Aql X-1. Optical photometry during an active state shows a strong (0.6 mag peak-to-peak) modulation at a period of 19 hours. Infrared (K ′ -band) photometry during a quiescent state limits any ellipsoidal variations to < 0.07 mag (peak-to-peak), which implies an inclination i < 31 o (90% limit). Spectroscopy in a quiescent state shows at most very small radial velocity variations, which implies a very low inclination of i < 12 o (90% limit). The low inclination is rather unexpected given the large photometric modulation seen in the active state. The upper limit to the equivalent width of the anomalous Li 6707Å line is < 0.3Å, which is similar to the measured strength of this line in several other x-ray transients.
