Acute Toxicity Of The Bird Repellent, Methyl Anthranilate, To Fry Of Salmo Salar, Oncorhynus Mykiss, Ictalurus Punctatus And Lepomis Macrochirus, Larry Clark, John Cummings, Steven Bird, Eugeny Aronov Jan 1993

Acute Toxicity Of The Bird Repellent, Methyl Anthranilate, To Fry Of Salmo Salar, Oncorhynus Mykiss, Ictalurus Punctatus And Lepomis Macrochirus, Larry Clark, John Cummings, Steven Bird, Eugeny Aronov

Larry Clark

Several laboratory and field studies have shown methyl anthranilate to be an effective, non-toxic and non-lethal bird repellent, with application potential for protecting crops, seeds, turf and fish stocks from bird damage. Furthermore, methyl anthranilate can be added to liquids for the purposes of protecting nigratory birds, e.g. addition to waste water associated with mining and to standing water pools at airports. Mammalian toxicity data are favorable. Methyl anthranilate is used as a fragrance and food flavoring and is GRAS listed by the US Food and Drug Administration. Despite the favorable outlook for methyl anthranilate's use as a ...


Atomic Force Microscopy And Manipulation Of Living Glial Cells, V. Parpura, P. G. Haydon, D. S. Sakaguchi, E. Henderson Jan 1993

Atomic Force Microscopy And Manipulation Of Living Glial Cells, V. Parpura, P. G. Haydon, D. S. Sakaguchi, E. Henderson

Zoology and Genetics Publications

The atomic force microscope (AFM) is capable of imaging surfaces at very high resolution. The AFM has been used to image living glial cells in culture. Typical images reveal the three‚Äźdimensional shape of the cell and often internal cellular structures are visible. In this report, it is shown that by increasing the imaging force, cells can be removed from the surface on which they are grown. Although the forces involved in this process are complex, it is possible to compare relative adhesion of different types of living cells to a particular substrate.


Molecular Analysis Of Protein Kinase C In The Sea Urchin Lytechinus Pictus , Terese Louise Rakow Jan 1993

Molecular Analysis Of Protein Kinase C In The Sea Urchin Lytechinus Pictus , Terese Louise Rakow

Retrospective Theses and Dissertations

Protein kinase C (PKC) was originally described as a serine threonine kinase in brain tissue. This activity was found to be dependent upon Ca[superscript]2+ and phosphatidyl serine. Today protein kinase C consists of a family of kinases with nine known members. Some members are Ca[superscript]2+-independent isozymes, and all of them have subtle activation differences. The multiple isozymes with varying activities in addition to different tissue distributions lead to the idea that members of the family have different functions. PKC has been well studied in mammalian systems and it is concluded that PKC is activated in ...


Characterization Of Cis-Acting Replication Control Elements In Ribosomal Rna Genes Of Tetrahymena Thermophila , Wen-Ling Shaiu Jan 1993

Characterization Of Cis-Acting Replication Control Elements In Ribosomal Rna Genes Of Tetrahymena Thermophila , Wen-Ling Shaiu

Retrospective Theses and Dissertations

This dissertation describes the identification and characterization of specific cis-acting replication control elements in the replication origin of Tetrahymena rDNA. Earlier studies of a mutant rDNA allele, C3-rmm1, identified a cis-acting sequence (the Type I repeat) within the 5[superscript]' non-transcribed spacer of rDNA that affects rDNA replication (Larson et al. 1986). Characterization of two additional, independently-isolated mutants (C3-rmm3 and C3-rmm4) and a revertant of C3-rmm4 strongly argue that the Type I repeat is indeed a cis-acting replication control element. Mutations causing rDNA replication defects were identified in copies of the Type I repeat that are separated by >600 bp ...


Tissue-Specific Regulation Of 1,25-Dihydroxyvitamin D Action In The Target Tissues Of Rats , Matthew John Beckman Jan 1993

Tissue-Specific Regulation Of 1,25-Dihydroxyvitamin D Action In The Target Tissues Of Rats , Matthew John Beckman

Retrospective Theses and Dissertations

Tissue response to 1,25(OH)[subscript]2D[subscript]3 action was evaluated by examining vitamin D-dependent VDR, 24-OHase, and CaBP mRNA expressions, 24-OHase activities, and VDR concentrations in kidney and intestine. Of 4 groups of rats, 2 groups were fed an adequate vitamin D (300-600 IU/wk), 1.0-1.2% calcium (Ca) diet, designated NC, and 2 groups were fed an adequate vitamin D, 0.02% Ca diet, designated LC. One group from each diet was treated with excess vitamin D[subscript]3 (75,000 IU/wk). These groups were designated NCT and LCT, respectively;Plasma 1,25(OH ...
