Coalescence of a Ferrofluid Drop at Its Bulk Surface with or without a Magnetic Field.

The coalescence of a ferrofluid drop at its bulk surface, with or without a magnetic field, was investigated experimentally by a high-speed camera. Shape deformations of both the pendant ferrofluid drop and the bulk surface in the axial direction were observed during the approaching process even in the absence of a magnetic field. The angle of the upper pendant peak at the first contact decreases with the magnetic flux density, while the lower ferrofluid peak displays an opposite trend.

Pregnancy during enzyme replacement therapy for late-onset acid maltase deficiency.

We report the case of a female patient who developed Pompe's disease when she was 19. She received enzyme replacement therapy from the age of 35, and after three years of treatment the improvement in her clinical condition was such that she was able to consider having a baby. It was the patient's wishes to continue with her treatment throughout the entirety of her pregnancy.
