    Transient bifrontal solitary periventricular cysts in term neonates (1994)

    Notes: Abstract We describe three children born at term investigated for neonatal seizures or transient apnoea. Cranial ultrasound and MRI unexpectedly revealed symmetrical periventricular cysts adjacent to the anterior horns. We found no evidence of prenatal viral infection, intraventricular or subependymal haemorrhage or hypoxic-ischaemic lesions. The lesions were not seen on MRI at 3 months of age, but there was no compensatory dilatation of the anterior horns nor secondary loss of white matter. The appearance and location of these transient cysts were different from those of the cystic changes which typically follow germinal matrix haemorrhage or periventricular leukomalacia. Their pathogenesis and clinical significance remain to be determined.

    The Renal Type II Na+/Phosphate Cotransporter (1998)
    Springer
    Journal of bioenergetics and biomembranes 30 (1998), S. 187-194 
    Details
    ISSN: 1573-6881
    Keywords: Proximal tubule ; transport ; phosphate ; regulation

    Notes: Abstract A sodium-dependent phosphate transporter (type II Na/Pi-cotransporter) was isolated which is expressed in apical membranes of proximal tubules and exhibits transport characteristics similar as described for renal reabsorption of phosphate. Type II associated Na/Pi-cotransport is electrogenic and results obtained by electrophysiological measurements support a transport model having a stoichiometry of 3 Na+/HPO4 =. Changes of transport such as by parathyroid hormone and altered dietary intake of phosphate correlate with changes of the number of type II cotransporters in the apical membrane. These data suggest that the type II Na/Pi-cotransporter represents the main target for physiological and pathophysiological regulation.
