The Flinders Technology Associates filter paper cards (FTA(®) cards) can be used to store nucleic acid from various samples and are easily portable. However, RNA is physicochemically unstable compared with DNA, and appropriate methods have not been established for storage and extraction of RNA from FTA(®) cards. The present study investigated the optimum conditions for storage and elution of vi...

BACKGROUND Annually, large quantities of dyes are produced and consumed in different industries. The discharge of highly colored textile effluents to the aquatic environments causes serious health problems in living organisms. This paper investigates the performance of each of the electro-oxidation and electro-reduction pathways in the removal of reactive red 120 (RR120) from synthetic textile ...

We explore electro-catalytic properties of a system consisting of platinum and palladium nanoparticles dispersed over a nanotubular self-organized TiO2 matrix. These electrodes prepared by electroess and microemulsion of palladium and palladium nanoparticles on to TiO2 nanotubes, respectively. Titanium oxide nanotubes were fabricated by anodizing titanium foil in ethylene glycol (EG) fluoride-c...

Background: Sachse cold knife is conventionally used for optical internal urethrotomy to manage urethral strictures. In this procedure, the complications and recurrence rates are relatively high. We suggest combined electro cutter and cold knife as a success alternative in the management of intractable anterior urethral strictures. Methods: In this prospective...

BACKGROUND Bipolar electro-coagulation has a reported efficacy in treating epilepsy involving functional cortex by pure electro-coagulation or combination with resection. However, the mechanisms of bipolar electro-coagulation are not completely known. We studied the acute cortical blood flow and histological changes after bipolar electro-coagulation in 24 patients with intractable temporal lobe...

AIMS This study sought to investigate the possible influence of different bifurcation stenting techniques on stent deformation, physical stress, and drug elution using a virtual tool that includes structural, fluid dynamics and drug-eluting numerical models. METHODS AND RESULTS A virtual bench test based on explicit dynamics modelling was used to simulate procedures on bifurcated coronary ves...

Moore and Stein (1) have reviewed the work of Boardman and Partridge and others on problems encountered in attempting the chromatography of nonbasic proteins on Amberlite IRC-50 by elution analysis with the use of buffers of constant composition for the elution. Boardman and Partridge (2) suggested that the difficulty in achieving reversible equilibrium binding was due to hydrogen bonding betwe...

An improved method for evaluating drug release behaviour of drug-eluting embolization beads (DEBs) was developed utilizing an open-loop flow-through system, in which the beads were packed into an occlusive mass within the system and extracted with a flowing elution medium over time. Glass beads were introduced into the beads mass in order to ensure laminar flow, reduce dead volume and improve r...
