An improved and simplified protocol for DNA immobilization was developed to enhance DNA-DNA hybridization on microwell plates. Target DNA was immobilized by simple dry-adsorption. Efficiencies of DNA immobilization and retention were enhanced 1.4-6.5 times and 4.2-19.6 times, respectively, compared with a conventional method. The overall hybridization efficiency was increased 3.1-5.2 times. Thi...
Drosophila melanogaster is able to thrive in harsh northern climates through adaptations in life-history traits and physiological mechanisms that allow for survival through the winter. We examined the genetic basis of natural variation in one such trait, female virgin egg retention, which was previously shown to vary clinally and seasonally. To further our understanding of the genetic basis and...
BACKGROUND Retention in treatment is a key indicator of methadone treatment success. The study aims to identify factors that are associated with retention. OBJECTIVES To determine retention in treatment at 12 months for Irish opiate users in methadone substitution treatment and to indicate factors that increase the likelihood of retention. METHODS National cohort study of randomly selected ...
In addition to kinematic description of biological reaction, flow pattern plays an important role in designing constructed wetlands. This study investigates the effects of flow distribution on constructed sub-surface horizontal flow wetland with a length of 26 m, width of 4 m and 1% bed slope in order to understand internal hydraulic functioning patterns. Inlet configuration is selected as a va...
