    Localization of nerve growth factor receptor mRNA in the rat basal forebrain within situ hybridization histochemistry (1990)
    Springer
    Cellular and molecular neurobiology 10 (1990), S. 33-39

    Notes: Summary 1. In situ hybridization histochemistry was used to localize nerve growth factor receptor (NGFR) mRNA in the adult rat basal forebrain. 2. In emulsion-dipped sections35S-labeled RNA antisense probes produced a high density of silver grains over cells located in the medial septum, vertical and horizontal limbs of the diagonal band of Broca, and nucleus basalis. 3. This distribution of NGFR mRNA overlaps with the distribution of NGFR protein localized using immunocytochemical techniques. 4. No hybridization signal was detected when sections were hybridized with a35S-labeled RNA sense (control) probe. 5. We suggest that NGFRs are synthesized in these basal forebrain nuclei and transported to terminal areas where NGF is thought to be bound and internalized, an initial step in the many actions of this neurotrophic factor.

    Growth inhibition by high light intensities in algae from lakes undergoing acidification (1989)
    Springer
    Hydrobiologia 184 (1989), S. 201-208 
    Details
    ISSN: 1573-5117
    Keywords: acidification ; algae ; Chrysochromulina ; Mougeotia ; photoinhibition

    Notes: Abstract Blooms ofChrysochromulina breviturrita Nich. (Prymnesiophyceae) have been found to be restricted to lakes above pH 5.5 even though the alga is able to tolerate pH 4.0 in laboratory culture. A possible explanation is the increased transparency in acidifying lakes and a sensitivity ofC. breviturrita to high light intensities. A comparison was made withMougeotia sp., a filamentous green alga which co-occurs in moderately acidic lakes and has a similar pH tolerance range. This alga forms dense, floating mats or amorphous clouds in the upper littoral zone, where it would be exposed to full sunlight irradiances. In cultures ofC. breviturrita, prolonged exposures to 1600 µE · m−2 · s−1 (I0′) resulted in reductions in cell yield which were dependent age at the onset of exposure to high light intensity. Only cultures exposed to high light intensities during late stationary phase were able to recover to control levels and no recovery occurred if these cultures were nitrogen deficient.Mougeotia was more tolerant of both high light intensity and nitrogen limitation during the recovery period. The inability ofC. breviturrita to recover from the effects of high light intensity during nitrogen deprivation may be particularly important in small, stratified lakes which are undergoing acidification. The slow rate of vertical circulation, and increasing transparency, would prolong exposure of the alga to the high irradiance levels of nutrient-deficient epilimnetic waters. This suggests that the geographic distribution ofC. breviturrita may be explained in part by the increasing light intensities in lakes undergoing acidification.

    Chromosomal mapping of T-DNA inserts in transgenicPetunia byin situ hybridization (1995)
    Springer
    Transgenic research 4 (1995), S. 241-246 
    Details

    Topics: Biology
    Notes: Abstract The chromosomal location of T-DNa inserts in ten independently derived and confirmed transgenic plants ofP. hybrida was detected byin situ hybridization. Nine transgenic plants had the T-DNA inerts at single sites distributed among each of the seven chromosomes; in one plant the T-DNA inserts were detected on two different chromosomes. Although the T-DNA inserts were integrated randomly among the chromosomes, seven of the 11 total inserts were located at or near the telomere. Thus, T-DNA inserts appear to have potential for tagging chromosomes and chromosome fragments.
