Undergraduate Honors Capstone Projects
Advances in in vitro fertilization and in vitro culture techniques have allowed considerable progress in identifying physiological requirements of mammalian embryos. Parrish et al. (11) reported a major breakthrough on in vitro fertilization when his group identified heparin as an important factor for the capacitation of spermatozoa. Capacitation is necessary for fertilization of matured oocytes. During the precoculture era of embryos (prior to 1980), the development of early preirnplantation embryos was vary limited regardless of medium, medium supplement, gas atmosphere, osmolarity or pH used (7). Coculture techniques of fertilized oocytes using somatic cells during in vitro production, particularly of bovine …

Cryptosporidium parvum, a protozoan parasite infecting epithelial cells lining the intestinal tract of animals and humans, causes fulminate diarrhea and malabsorption of essential nutrients following damage to the cellular brush border. The present study was undertaken to evaluate the use of a pentose sugar (D-xylose) in a standardized tolerance test as an indicator of malabsorption due to cryptosporidiosis in the dexamethasone (DEX)-immunosuppressed adult C57BL/6N mouse model. One group containing 14 experimental mice (in addition to appropriate control groups) was immunosuppressed using daily intraperitoneal injections of DEX (125 μg/mouse). On day 7 postimmunosuppression, mice were inoculated orally with 104 C. …
