Chua, Leslie Anne K.; Panlilio, Robin A. (2002-04)

Random Amplified Polymorphic DNA (RAPD) analysis was applied to three previously recognized species of Oliva from the Visayas. Total genomic DNA was extracted from the ethanol-preserved samples following the method of ...
Cadmium Tolerance in Golden Kuhol Pomacea canaliculata (Lamarck, 1819)

Ocampo, Melody Anne B.; Reyes, Katrina Louise Q. (2002-04)

Cadmium tolerance in terms of cadmium uptake (in mg/L) from the aquatic environment, was studied in golden kuhol (Pomacea canaliculata). Snails of different ages (one-month and three-months old) were exposed to varying ...
Single Stranded Conformation Polymorphism Analysis of the Human p-Defensin 2 Gene In Filipino Tuberculosis Patients

Cordova, Liezl Marie Gaston; Lirazan, Ryan Joseph Balagtas (2003-03)

Human Beta-Defensin 2 (hBD2) works as a host defense antimicrobial peptide against Mycobacterium tuberculosis, the causative agent of tuberculosis (TB). Genomic DNA from representative samples (TB03 and Cl2) was subjected ...
