Isozyme Polymorphism of Selected Cultivars of Table- and Cooking-type Banana (Musa sp.) in the Philippines and Genome Identification of the Table-type Cultivars

Isozyme profiles of 20 table-type and 6 cooking-type banana (Musa sp.) cultivars were studied.  The different isozymes used include malate dehydrogenase (MDH), 6-phosphogluco dehydrogenase (PGD), phosphoglucoisomerase (PGI), and phosphoglucomutase (PGM).  Different banding patterns were observed.  Banding patterns (BP) of the different cultivars with known genomes (18) were compared with newly collected cultivars (5 table-types; 3 cooking-type) with unknown genome (UK) to determine the genome identity of the latter. The 4 isozymes were not useful in identifying the genome of the 3 cooking-type cultivars . . . . read


Zebrafish Syntenic Relationship to Human/Mouse Genomes Revealed by Radiation Hybrid Mapping

Zebrafish (Danio rerio) is an excellent model system for vertebrate developmental analysis and a new model for human disorders. In this study, however, zebrafish was used to determine its syntenic relationship to human/mouse genomes using the zebrafish-hamster radiation hybrid panel. The focus was on genes residing on chromosomes 6 and 17 of human and mouse, respectively, and some other genes . . . . read


Life Strategies of Mosses in Mt. Pulag, Benguet Province, PhilippinesMt. Pulag, the highest peak in Benguet Province, Luzon Island, Philippines at 2,924 m (Buot and Okitsu 1998) was investigated for its moss flora focusing on life strategies.   Moss collections totaled 58 species that belong to 28 families.  These are distributed among 3 vegetation zones; the pine forest, mossy . . .

Fabrication of a Sensor using Seed Lectin in Voltammetric Detection of Heavy MetalsThis study made use of a seed lectin as biological component of a metal sensor. Red kidney bean (Phaseolus vulgaris) seeds that served as source of lectin, were extracted with Tris buffered saline (TBS, 0.01 M in 0.15 M NaCl pH 7.5) solution, followed by ammonium sulfate precipitation (0-90%) . . .

Copper Oxide as Mediator for the Amperometric Determination of Hydrogen PeroxideCopper oxide (CuO) was investigated as a mediator for the amperometric determination of hydrogen peroxide. Screen-printed carbon electrodes (SPCEs) have been prepared with chemical modification by CuO. The basic electrochemical behaviour . . .

Double-bridged Tetrathiafulvalene Macrocycles with m-Xylylene, Trimethylene and Glucose Linkers: Synthesis and CharacterizationThe synthesis of novel tetrathiafulvalene (TTF) macrocycles with m-Xylylene, Trimethylene, and Glucose units is reported. The synthesis involves the preparation and stepwise base deprotection of . . .

Decolorization of Glucose-Glycine Melanoidin as Model Color Pollutant Using Ozonation and Bacterial TreatmentMelanoidin was prepared as model color pollutant by heating equimolar amounts of glucose and glycine in sodium carbonate solution for 3 h at 121o C. After partial purification by Sephadex G-100 chromatography it was ozonated and then . . . .

Detection of Anti-HBs, Anti-HBc and HBsAg among Pediatric Vaccinees Years after Primary Hepatitis B ImmunizationA serological survey recruited 321 pediatric Hepatitis B (HB) vaccinees to : (1) determine the prevalence of anti-HBs years after HB immunization with either a 1.5 µg-dose plasma derived vaccine or a 10 µg-dose recombinant DNA vaccine, (2) determine anti-HBc . . .
