    Expressions of a calcium-binding protein (spot35/calbind in-D28k) in mouse olfactory cells: Possible relationship to neuronal differentiation (1997)

    Notes: Abstract We used immunohistochemistry to investigate the expression of spot35/calbindin-D28k (calbindin) in mouse olfactory epithelium during development. Cell stages of immunopositive olfactory cells were determined by comparing the levels of proliferating cell nuclear antigen (PCNA). Calbindin-positive cells were abundant in the middle layer of the epithelium of animals before 2 weeks of age and gradually diminished during development. Only low levels were detectable near the basement membrane in the adult. Changes of calbindin-positive cells in terms of number and distribution were apparently compatible with localization changes of premature olfactory cells. PCNA overlapped calbindin in the nasal mucosa at lower magnifications on stained serial sections and immunohistochemical double staining revealed that calbindin-mmunoreactive cells were located mainly just above PCNA-immunoreactive cells in the basal layer of the epithelium. This indicated that calbindin is expressed postmitotically in immatureolfactory cells and is lost by mature cells. These findings suggest that calbindin might support the maturation of the olfactory cells, such as the projection of the neuronal processes, by stabilizing intracellular calcium ions in immature cells.

    Age-related changes in dividing cells of the olfactory epithelium of the maturing guinea pig (1998)

    Notes: Abstract Changes in dividing cells of the olfactory epithelium from guinea pigs of different ages were examined by immunohistochemical staining using anti-proliferating cell nuclear antigen antibody. Numerous dividing cells were scattered diffusely in the basal layer of the olfactory epithelium at 1 and 2 months following birth and then gradually decreased with maturation until 4 months. Findings then remained constant between 4 and 24 months. Subsequently, cell numbers were found to decrease as animals became older. The number of olfactory receptor cells did not vary significantly between 1 and 30 months. Although no correlation could be found between the numbers of dividing cells and olfactory receptor cells, it is still possible that the longevity of the olfactory receptor cells changes to maintain the overall size of the neuronal population.

    STM tunneling spectroscopy on high Tc superconductors (1995)

    Notes: Abstract STM tunneling spectroscopy has been performed on the bulk single crystals of BiSrCaCuO (BSCCO) and the epitaxial thin films of YBaCuO (YBCO) at cryogenic temperatures. The STM images and tunneling spectra observed on the (001) surfaces can be classified into three cases; 1) Atomic image is visible. However, the tunneling spectrum shows semiconducting or smeared superconducting gap structures, depending on the tip-sample distance. 2) Clear atomic image can not be obtained. But, the tunneling spectrum shows flat bottom region with quite low zero bias conductance. 3) Tunneling spectra demonstrate gapless behavior, independent of the tip-sample separation. These observations support the quasi-2D electronic picture in whichs-wave like 2D superconducting layers are coupled with each other through the Josephson effect.
