Granule cell raphes in the cerebellar cortex of chicken and mouse.

The cerebellar cortex of the chicken embryo contains parasagittal segments of Purkinje cells. At intermediate stages of development, cell-dense ribbons of migrating granule cells ("raphes") are found between the segments. The complementary pattern of granule cell raphes and Purkinje cell segments represents a basic scheme of cerebellar organization that coincides with the expression domains of various genes, such as cadherins, gene regulatory proteins, and ephrins and their receptors. We have recently found the raphe/segment pattern also in a mammalian species, the postnatal mouse. Like in the chicken, the parasagittal raphes of granule cells were observed at the boundaries of Purkinje cell segments that differentially express cadherins. The number and arrangement of the raphes in the different cerebellar lobules is roughly similar in both species. The raphe/segment pattern is thus more widely distributed in vertebrates than previously assumed.

Specialisation in nursing: are we ready for the year 2000?

The development of specialty nursing practice and nurse specialists in today's health care arena is a controversial yet growing force, fuelled by a complexity of factors from both within and external to the profession. By narrowing the focus on parts of the whole field of nursing, nurses have met the challenge of increasing technology, complexity of the health care system, and nursing care needs. Although the debate regarding nurse specialists continues to rage, the production of such nurses will push beyond the boundaries of the profession into the new millennium, in the interests of patient care.
