At the Salnikov Cup in St Petersburg, Daniel Isotov (RUS) clocked 46.16 in the 100m free ahead of Evgeny Lagunov, on 46.56, with Fred Bousquet (FRA) on 47.12 and Paul Biedermann (GER) on 47.89. Isotov won the final in 45.71, Lagunov clocked 45.81 and Bousquet 45.88, Biedermann improving to a 46.63

 Biedermann clocked 3:47.85 in the 400m free heats ahead of Russians Vitaly Romanovich, 3:48.11, and Mikhail Polischuk, on 3:48.22, with Mads Glaesner (DEN) on 3:48.33. Biedermann won the final in 3:37.20, ahead of Glaesner, on 3:39.10 and Plischuk on 3:40.55.

Not sure if officials were uber-eagle-eyed or whether organisers have got their codes mixed up on the official result sheets but disqualifications were registered against Mads Glaesner (DEN) in the 200m medley, Fred Bousquet in the 50m 'fly, Helge Meeuw (GER) in the 100m backstroke, Antje Buschschulte (GER) in the 100m butterfly (I thought she had officially retired - but she's back to add grace to the race pool once more in textile), Rikke Moeller Pedersen (DEN) in the 100m breaststroke (she actually set an European record in the final...) and several Russians in various events. It could be that the DSQ code was being used for did not swim. Unsure at this stage 

Update, a source in St Petersburg tells SwimNews that the DSQ is indeed a code error and means Did No Swim.  One of the oddities of the meet is that the 400m medley may be swum in any order of strokes and the distances over which the strokes are swum, within the 100m per stroke limits, so you could do 4x100m medley, for example.
