Microbiology: Gram-Positive Bacteria Cells
[ send me this essay ]
This is a 3 page paper discussing Gram-positive bacteria. In the study of microbiology, common Gram-positive bacteria cells are Straphlyococcus aureus or Streptococcus cremoris often used in dairy production. Gram-positive bacteria are considered distinct in their multiple layered cell walls almost made up entirely of peptidoglycan. Gram-positive bacteria have four associated families which include Bacillaceae, Micrococcaceae, Mycobacteriaceae, and Peptococcaceae all of which vary in their growth rates, motility, and the media on which they grow. In addition, some Gram-positive bacteria have the ability to produce specific biochemical activities and/or specific toxins. Because of this, Gram-positive bacteria are sometimes used for fermentation, the reduction of nitrate or the production of coagulase or catalase among other uses.

Mineral, Energy, and Water Resources of Kentucky
[ send me this essay ]
A 17 page overview of the natural resources of the state of Kentucky. Provides a broad overview of the types of minerals which exists in the state and emphasizes that mining, while necessary to the economy and energy needs of the state, can have tremendous environmental impacts. Summarizes the importance and impact of limestone mining in particular and cautions that mining alone is not the only adverse environmental impact in the state of Kentucky. Outlines the importance of the states water bodies (including a two page list of some of the most noted) and wetlands and the impacts of such activities as the construction and operation of hydroelectric dams and domestic wastewaters. Bibliography lists 11 sources.

Misunderstanding Homosexuality and Gay Relationships from Psychological, Biological, and Social Perspectives:
[ send me this essay ]
In seven pages this paper examines the impetus for the gay riots and subsequent Gay Revolution that took place in June-July 1969 at Greenwich Village’s Stonewall Inn as chronicled in David Carter’s Stonewall and also examines the misunderstandings associated with homosexuality and gay relationships from biological, psychological, and social perspectives. Four sources are listed in the bibliography.

Molecular Aspects of Latency in Herpes Simplex-1
[ send me this essay ]
A 15 page sequel to KS-HSV.wps expanding on the more basic principles of that first paper. This paper
focuses exclusively on HSV-1 and explores issues such as gene expression, gene products, function and possible mechanisms of action of the latency-associated gene expression in
much greater depth. It also goes into more highly detailed discussion of molecular conditions and actions in the establishment of latency. Bibliography lists 10 sources.

Molecular Mixtures and Cross-Membrane Transport
[ send me this essay ]
A 5 page review of “Drug Delivery: Breaching the Membrane”, an article by Joe Alper published in the May 3, 2002 edition of “Science”. Alper’s (2002) research concentrates on the cell membrane and the manner in which cross-membrane transport occurs, specifically the manner in which membrane-bound protein transporters function to allow various nutrients and hormones across. Alper’s paper adds insight to both the structure and function of the cell membrane and its components and how each relates to the molecular structure of the body’s complex mixture of chemicals. No additional sources are listed.

Molecular Modeling: Conformation Analysis and Energy Minimization
[ send me this essay ]
A 6 page paper discussing these two aspects of computational chemistry. The next generation of narrowly-targeted drugs seems to be about to appear over the horizon. Conformation analysis and molecular modeling play increasing roles in new drug research. Conformation is important in that it can change according to its environment; energy levels affect action. Drug developers need to discover the most effective conformation, but they also need to be able to retain that conformation despite conditions external to the molecule. Bibliography lists 7 sources. Includes a Newman projection diagram.

Molecular Nature of Latency in Herpes Simplex
[ send me this essay ]
A 15 page paper discussing the
mechanisms by which Herpes simplex can lie dormant for years and then reappear. An individual's first experience with Herpes simplex is not his last. Once there has been an
initial outbreak, viral DNA finds its way to the nuclei of neurons of the sensory nervous system. There it lies dormant until stimulated to again become active. The ability of Herpes simplex to become latent and then reactivate has been implicated as having a role in some forms of cancer, as well as facilitate the transmission of HIV. Bibliography lists 14 sources.
Filename: KS-HSV.wps
Monoclonal Antibody
[ send me this essay ]
This 5 page paper provides an overview of monoclonal antibody and its potential uses. The concept is defined. Its role in potentially curing cancer is highlighted. Bibliography lists 5 sources.
