Presynaptic nicotinic acetylcholine receptors on striatal nerve terminals modulate the release of dopamine. Using rat striatal synaptosomes loaded with [3H]dopamine, we have characterized the action of the selective nicotinic agonist, (+/-)anatoxin-a, with respect to [3H]dopamine release, in order to explore the mechanisms coupling nicotinic receptor(More)
Coronavirus-cell entry programs involve virus-cell membrane fusions mediated by viral spike (S) proteins. Coronavirus S proteins acquire membrane fusion competence by receptor interactions, proteolysis, and acidification in endosomes. This review describes our current understanding of the S proteins, their interactions with and their responses to these(More)
A time and motion study was conducted to determine the produciivity and cost of an in-woods chipping operation when processing whole mall-diameter trees for biomoss. The study removed biomass from two overstocked stands and compared the cost of this treatment to existing alternatives. The treatment stands consisted of a 30-year-old longleaf pine stand and o(More)
There is an increasing interest in the establishment of plantations in the Southeast region with the objective of producing biomass for energy and fuel. Establishment of these plantations will require the development of a feasible way to harvest them. These types of plantations are called Short Rotation Woody Crops (SRWC). Popular SRWC species are Eucalypt(More)
Although there is renewed interest in intensively managed, short-rotation plantations as a source of hardwood for pulp mills, few have been established in the Southeast. Understanding all the costs associated with these plantations will help determine their feasibility. Using a model developed to summarize all the costs, a break-even analysis was completed(More)
Small bowel contractility may be more prominent in obese subjects, such that there is enhanced nutrient absorption and hunger stimulation. However, there is little evidence to support this. This study examined in vitro small bowel contractility in obese patients versus non-obese patients. Samples of histologically normal small bowel were obtained at(More)
John Deere's biomass bundler unit is an effective machine for harvesting forest residues, which can be used as a source of fuelwood and/or a feedstock for biofuel production. This project explored an avenue that could supply a promising source of readily available energy in southeastern forested lands. Typical southern harvesting operations consist of(More)
Enormous amounts of untapped energy sources exist within the forestry realm. With the current energy crisis and with petroleum prices skyrocketing, all sources of alternative fuels need to be explored. John Deere's Biomass Bundler unit is an effective machine for harvesting forest residues, which can be used as a source of fuel wood and/or a feedstock for(More)
