The Effect Of Ergosterol On The Desaturation Of 14c-Labeled Oleic Acid In Tetrahymena, Maynard E. Neville Jr.

Masters Theses

The ciliated protozoan Tetrahymena pyriformis-Strain W desaturated ¹⁴C-labeled fatty acid substrate in both sterol supplemented (ergosterol) and nonsupplemented cultures. Cis-octadecenoic acid (¹⁴C-9-18:1), when added to the medium during the log phase of growth, was incorporated into the cells and also desaturated at the Δ⁶ and Δ¹² positions. The ¹⁴C labeled substrate and products, linoleate (9,12-18:2) or linolenate (6,9,12-18:3) were recovered and separated by silver-nitrate Unisil column chromatography. Initially, recovery of ¹⁴C compounds varied widely when expressed as the percent of total counts per minute recovered from column chromotography, and a variety of …

The Effects Of Superovulation On The Reproductive Cycle Of Mature Female Mus Musculus, David F. Grace

Masters Theses

A total of 38 Mus musculus were used to compare superovulation to normal ovulation in three different areas of the reproductive cycle. The areas studied include the fertilization and abortion rates, alternation of ovarian function, and normalization of estrus cycling. No statistically significant differences were noted between the two groups in either fertility rates or abortion rates. A distinct difference was noted in alternation of ovarian function. Normally ovulating mice showed a distinct right or left preference in the number of ova ovulated from each ovary. Animals showing a left preference exhibited approximately a 2:1 ratio and animals with a …

Seasonal Diversities Of Lotic And Lentic Benthic Insect Populations, Jerry E. Bindel

Masters Theses

The benthic insect populations from Lake Charleston and the Embarras River above and below Lake Charleston were examined twice monthly for seasonal differences in number of organisms, number of taxa and species diversity from October 13, 1976 to February 16, 1977. The water quality parameters of alkalinity, carbon dioxide, dissolved oxygen, pH and temperature were also examined for each site to determine if any parameter showed a sufficient deviation as to exert an influence on the benthic insect populations. Low dissolved oxygen and high carbon dioxide values were noted and occurred at times corresponding to lower numbers of taxa and …

A Cytogenetic Study Of Xx/Xy Chimerism And Other Anomalies Of Bos Taurus In A Sampled Dairy Herd, Ferne M. Rogers

Masters Theses

The establishment of normal chromosomal patterns for a wide range of plants and animals has led to the recognition of abnormalities as well as their relationship to phenotypic irregularities. Research dealing with the expression of human karyotype is of prime interest; but, closely rivaling that is the genetic study of domestic animals which are of economic importance to man.

One observed anomaly which has come under scrutiny by cytogeneticists is that of the female member of a heterogeneous bovine twin pair, the freemartin. This is a sterile animal with internal morphology showing varying degrees of intersex. Cytogenetic studies reveal XX/XY …

Petrology Of The Rockport Quarry Limestone (Middle Devonian Traverse Group) Alpena, Presque Isle And Montmorency Counties, Michigan, Charles Willard Cookman

Masters Theses

The basal unit of the dominantly carbonate Traverse Group, the Bell Shale, is gradationally overlain by the Rockport Quarry Limestone which has a thickness of approximately 14 m. The Rockport Quarry Limestone is composed of a dark unrestricted marine subtidal organic-mud packstone facies, comprised of an algal-mat-bearing coral packstone subfacies and a shallower water crinoid-bryozoan grainstone subfacies; a shoal forming stromatoporoid biolithite facies; and a lagoonal micrite facies comprised of a subtidal dense subfacies containing gastropods, ostracods, and calcispheres, and an Intertidal to supratidal fenestral subfacies. The local facies tract reconstructed for the Rockport Quarry Limestone is interpreted to be …
