Morphine Concentrations in Human Urine Following Poppy Seed Paste Consumption.

Papaver somniferum (opium poppy) is one of the world's oldest medicinal plants which are widely used for medicinal, nutritive and scientific purposes. Turkey is one of the major legal opium poppy producer countries in the world and the seed paste of the poppies is consumed in great deal, even more than 100g per meal. The main objective of this study is to investigate the influence of poppy seed paste ingestion on urine tests for opiates whether or not could lead to opiate positive urine test results.

DNA isolation by galactoacrylate-based nano-poly(HEMA-co-Gal-OPA) nanopolymers.

Isolation of DNA is one of the important processes for biotechnological applications such as investigation of DNA structures and functions, recombinant DNA preparations, identification of genetic factors and diagnosis and treatment of genetic disorders. The aim of this study was to synthesis and characterizes the galactoacrylate based nanopolymers with high surface area and to investigate the usability of these synthesized nanopolymers for DNA isolation studies. Nanopolymers were synthesized by the surfactant free emulsion polymerization technique by using the monomers of 2-hydroxyl ethylmethacrylate and 6-O-(2-hydroxy-3-acryloyloxypropyl)-1,2:3,4-di-O-isopropylidene-α-D-galactopyranose.
