Oral Cancer Screening, Damon Omar Watson Jun 1997

Oral Cancer Screening, Damon Omar Watson

Honors Theses

Cancers of the oral cavity and pharynx have increased throughout the decades. Since oral cancer represents a small percentage of the total cancers in the United States, it is often overlooked. Though this is the case, the results of this cancer can be devastating. To address this issue, an Oral Cancer Screening was organized on August 14, 1996 at the West Michigan Cancer Center in Kalamazoo. This was a joint collaboration between the author, the West Michigan Cancer Center, and the Kalamazoo Valley Dental Society. This event allowed research to take place concerning the data obtained. Confidential results and information …


The Effects Of Strain Differences On The Binding Of Concavalian A To Mouse Sperm, Lisa A. Mckay Jun 1986

The Effects Of Strain Differences On The Binding Of Concavalian A To Mouse Sperm, Lisa A. Mckay

Honors Theses

The current study, lectins were used as genetic probes to determine the phenotype of the sperm from different strains of mice. Lectins are proteins of non-immune origin, which bind to specific carbohydrates (McCoy, 1986). Being that virtually all cell membranes contain carbohydrate components, lectins have been used to identify all types of cells. In this study, a biotinylated lectin Concavalian A (Con A) derived from Canavalia ensiformis, was used and binding was detected using an avidin-biotin peroxidase (ABP) complex technique. The object of the current research was to 1) determine if mouse strain differences have an effect on lectin binding, …


Cytogenetic Test Of Captan And Triethylenemelamine In Mouse Bone Marrow, Stephen M. Fry Apr 1977

Cytogenetic Test Of Captan And Triethylenemelamine In Mouse Bone Marrow, Stephen M. Fry

Honors Theses

Following a single non-toxic i.p. injection with 0.5 or 1.0 mg triethylenemelamine/kig a significant increase in chromosome aberrations in mouse bone marrow was observed 6, 12, 30, but not 54 h after treatment. A single i.p. injection with 250 mg captan/kig caused up to 68% lethality above controls, but no significant increase in chromosome aberrations after the same time intervals. One metacentric chromosome was observed 6, 30, and 54 h after captan treatment among 300, 300, and 101 metaphase spreads respectively, whereas none appeared in 1495 control spreads.


Experimentation To Develop Procedures To Be Used In The Investigation Of The Effects Of Restriction On The Unmodified Dna Of The Bacteriophage Lamda, John Haynes Jun 1973

Experimentation To Develop Procedures To Be Used In The Investigation Of The Effects Of Restriction On The Unmodified Dna Of The Bacteriophage Lamda, John Haynes

Honors Theses

The results of experimentation approximately twenty years ago with variuos bacteriophages by Ralston and Krueger16, Anderson and Felix1, Luria and Human12, and by Bertani and Weigle2 have shown that the host range of a given phage depends directly on the bacterial strain on which the phage has last propagated. This event came to be known as host-induced modification or host-controlled variation. As this phage host range is controlled by the host environment and can be altered from one generation to another it has, according to Luria, made microbiology "the last stronghold of Lamarckism" …
