This paper aims to analyze the kind of information published by the Brazilian 'written media' about drugs. It was examined articles about drugs in a national circulation magazine between 1999 and 2003, through an analysis of content. A total of 481 articles were found. 'Consumption' was the most appeared topic. The most quoted drugs were: cocaine (21%), marijuana (19%), alcoholic beverages (12%) and cigarettes (12%). This research also showed that 57% of the articles were related to cigarettes, its harmful effects, whereas alcohol had the same amount of articles showing it as a good or a bad substance for the human being and considered the most addictive drug (23%). On the other hand, cocaine was related to drug dealing (30%). In general, cocaine and marijuana were in focus in the media while alcohol and solvents had less prominence considering the epidemiologic data of use. We can notice that there is an incompatibility between the media focus and the profile of drug consumption in Brazil, that could influence the person's beliefs about certain substances and public politics about drugs in Brazil.

Background: Three dimensional (3D) cell cultures can be effectively used for drug discovery and development but there are still challenges in their general application to high-throughput screening. In this study, we developed a novel high-throughput chemotherapeutic 3D drug screening system for gastric cancer, named 'Cure-GA', to discover clinically applicable anticancer drugs and predict therapeutic responses.
Methods: Primary cancer cells were isolated from 143 fresh surgical specimens by enzymatic treatment.

This study aims to explore the development of natural bio-based amphiphilic block copolymers for drug delivery applications. We investigated block copolymers derived from tamarind seed xyloglucan and solanesol, focusing on their synthesis, structural analysis, aqueous self-assembly, and drug encapsulation. Specifically, xyloglucan hydrolysate segments with number-average degrees of polymerization (DPs) of between 8 and 44 (XOS, XMS, XMS, XMS, and XMS) were used as the hydrophilic blocks, whereas plant-sourced solanesol was selected as the hydrophobic segment.

Urban stormwater pollution poses serious risks to human and environmental health, including trace metals toxicity. To improve the performance of existing highway Vegetated Filter Strips (VFS), which have limited performance for volume reduction and pollutant removal, amendment with a Vegetated Compost Blanket (VCB), a layer of seeded compost, has been proposed. A novel VCB/VFS system was assessed as a Stormwater Control Measure (SCM) via particulate matter and trace metals removal performance.
