Bacterial Survey of Representative Denton County Wells with Special Reference to Sanitation

Description: This thesis aimed to study the seventy-two representative wells of Denton County and to determine the possibilities of infection with typhoid organism. The sanitary survey and the test for Colon-Aerogenes bacteria show that 55% of the 72 wells studied are unsanitary, 27% are sanitary, and 18% are doubtful.

A Study of the Phytoplankton Population of Lake Dallas

Description: The limnological investigation of any body of water is undertaken in order to secure more accurate information concerning the factors which play an important role in fish production or sanitation. This study shows the qualitative and quantitative planktonic algae in Lake Dallas, for the year 1937-38.

Studies on Tissue Factor Pathway Inhibitor in Zebrafish

Description: Tissue Factor Pathway Inhibitor (TFPI) is an anticoagulant protein containing three Kunitz domains, K1, K2 and K3. K1 inhibits Factor VIIa, K2 inhibits Factor Xa, and K3 enhances the Factor Xa inhibition by its interaction with Protein S. Since zebrafish is an excellent genetic model, we hypothesized that TFPI regulation could be studied using this model. As a first step, we confirmed the presence of tfpia in zebrafish. Subsequently, we performed knockdown of tfpia, and knockout of tfpia in K3 … more
