The Homeo Domain Of A Murine Protein Binds 5' To Its Own Homeo Box., Abraham Fainsod, Leonard D. Bogarad, Tarmo Ruusala, Martin Lubin
The Homeo Domain Of A Murine Protein Binds 5' To Its Own Homeo Box., Abraham Fainsod, Leonard D. Bogarad, Tarmo Ruusala, Martin Lubin
Dartmouth Scholarship
Nuclear protein extracts from day 12.5 mouse embryos were used to study protein binding to DNA sequences 5' of the Hox 1.5 homeo box. Embryos of this developmental stage are known to express this gene. DNA binding protein blotting and retardation gel techniques show that murine embryonic nuclear proteins specifically bind a 753-base pair (bp) DNA fragment from the region upstream of the Hox 1.5 homeo box. A fusion protein containing the Hox 1.5 homeo domain constructed in lambda gt11 also binds the same 753-bp DNA fragment. Specific binding of the fusion protein to the upstream DNA fragment shows that …
Study Of A Small Mammal Population In Bowling Green, Kentucky, Richard Cambron
Study Of A Small Mammal Population In Bowling Green, Kentucky, Richard Cambron
Masters Theses & Specialist Projects
The small mammal population of a restricted study area was live-trapped on the University farm at Western Kentucky University from November 1984 through November 1985. A total of 1800 trap-nights yielded 81 different individuals representing five species. Members of the genera Peromyscus and Microtus were the dominant individuals representing over 90% of the total. Also caught were Mus musculus and Blarina brevicauda. The members of the two major genera were examined for population size and dynamics. In addition, a statistical analysis was carried out on the randomness of the location of the home ranges. This analysis gave evidence that …
Atp-Dependent Formation And Motility Of Aster-Like Structures With Isolated Calf Brain Microtubule Proteins., Richard C. Weisenberg, Robert D. Allen, Shinya Inoue
Atp-Dependent Formation And Motility Of Aster-Like Structures With Isolated Calf Brain Microtubule Proteins., Richard C. Weisenberg, Robert D. Allen, Shinya Inoue
Dartmouth Scholarship
Microtubule proteins isolated from calf brain will undergo gelation-contraction in the presence of ATP. We have now examined this process by video-enhanced contrast microscopy. After ATP addition to steady-state microtubules, slow (1-5 micron/min), linear movements of particles and microtubules toward aggregation centers occur. The resulting structures resemble mitotic spindle asters. During the time when gel contraction occurs, asters move (at 1-5 micron/min) toward other nearby asters. This is accompanied by the apparent shortening of the microtubules running between the asters. This is the first example of isolated microtubules undergoing a process that has similarities to half-spindle shortening during anaphase A. …
Absence Of A Structural Basis For Intracellular Recognition And Differential Localization Of Nuclear And Plasma Membrane-Associated Forms Of Simian Virus 40 Large Tumor Antigen., Donald L. Jarvis, Charles N. Cole, Janet S. Butel
Absence Of A Structural Basis For Intracellular Recognition And Differential Localization Of Nuclear And Plasma Membrane-Associated Forms Of Simian Virus 40 Large Tumor Antigen., Donald L. Jarvis, Charles N. Cole, Janet S. Butel
Dartmouth Scholarship
The simian virus 40 large tumor antigen (T-ag) is found in both the nuclei (nT-ag) and plasma membranes (mT-ag) of simian virus 40-infected or -transformed cells. It is not known how newly synthesized T-ag molecules are recognized, sorted, and transported to their ultimate subcellular destinations. One possibility is that these events depend upon structural differences between nT-ag and mT-ag. To test this possibility, we compared the structures of nT-ag and mT-ag from simian virus 40-infected cells. No differences between the two forms of T-ag were detected by migration in polyacrylamide gels, by Staphylococcus aureus V8 partial proteolytic mapping of methionine- …
G86-790 Fumigating Farm-Stored Grain With Aluminum Phosphide (Revised May 1998), Clyde Ogg, David L. Keith
G86-790 Fumigating Farm-Stored Grain With Aluminum Phosphide (Revised May 1998), Clyde Ogg, David L. Keith
University of Nebraska-Lincoln Extension: Historical Materials
This NebGuide provides step-by-step instructions for fumigating stored grain on the farm with aluminum phosphide.
Fumigants act on all insect life stages. They control pests by diffusing through the air spaces between grain kernels as well as into the kernel itself. Fumigants are able to penetrate into places that are inaccessible to insecticide sprays or dusts.
Regardless of formulation, all fumigants are poisonous and toxic to humans and other warm-blooded animals as well as to insects and other pests. Because fumigant chemicals are highly toxic and hazardous to use, they are Restricted Use pesticides. They can only be used by …
