Development of hydrophilic nanocarriers for the charged form of the local anesthetic articaine
(Colloids And Surfaces B-biointerfaces, 2014-09-01) [Artigo]
One of the current challenges in drug encapsulation concerns the development of carrier systems for hydrophilic compounds. Potential carriers include nanocapsules prepared with amphiphilic polymers, which consist of a ...
Application of poly(epsilon-caprolactone) nanoparticles containing atrazine herbicide as an alternative technique to control weeds and reduce damage to the environment
(Journal of Hazardous Materials, 2014-03-15) [Artigo]
Nanoparticles of poly(epsilon-caprolactone) containing the herbicide atrazine were prepared, characterized, and evaluated in terms of their herbicidal activity and genotoxicity. The stability of the nanoparticles was ...
Assessment of the Removal Capacity, Tolerance, and Anatomical Adaptation of Different Plant Species to Benzene Contamination
(Water Air And Soil Pollution, 2014-08-01) [Artigo]
The medium most directly affected by anthropic contamination is soil and, hence, groundwater (saturated and unsaturated zones). In the phytoremediation process, the direct absorption of soil contaminants through the roots ...
Effect of Silver Nanoparticles in a Hydroxyapatite Coating applied by Atmospheric Plasma Spray
(International Journal Of Electrochemical Science, 2014-12-01) [Artigo]
In this study, 0.5, 1, 3, and 5 % nano-silver containing hydroxyapatite coatings (nAg-HA) on a Ti6Al4V substrate were developed by atmospheric plasma spray (APS), and their antibacterial efficiency was evaluated in the ...
Short-term effect of alginate-biochar microbeads in corn germination
(International Proceedings of Chemical, Biological and Environmental Engineering, 2014) [Artigo]
Biochar is the solid by-product of biomass pyrolysis. It is a promising soil conditioner and can be a material with high aggregate economic value, since its performance can improve plant’s nutrient utilization and reduce ...
Chitosan/tripolyphosphate nanoparticles loaded with paraquat herbicide: An environmentally safer alternative for weed control
(Journal Of Hazardous Materials, 2014-08-15) [Artigo]
Paraquat is a fast acting nonselective contact herbicide that is extensively used worldwide. However, the aqueous solubility and soil sorption of this compound can cause problems of toxicity in nontarget organisms. This ...
Evaluation of the nanoherbicide activity against mustard plants
(Abstracts Of Papers Of The American Chemical Society, 2014-08-10) [Resumo]
Spatial Distribution of the Risk of Dengue and the Entomological Indicators in Sumare, State of Sao Paulo, Brazil
(PLoS Neglected Tropical Diseases, 2014-05-01) [Artigo]
Dengue fever is a major public health problem worldwide, caused by any of four virus (DENV-1, DENV-2, DENV-3 and DENV4; Flaviviridae: Flavivirus), transmitted by Aedes aegypti mosquito. Reducing the levels of infestation ...
Ecotoxicological Evaluation of Poly(epsilon-Caprolactone) Nanocapsules Containing Triazine Herbicides
(Journal of Nanoscience and Nanotechnology, 2014-07-01) [Artigo]
The triazine class of herbicides includes the compounds ametryn, atrazine, and simazine, which are used to control weeds in plantations of crops such as maize, sorghum, and sugar cane. Despite their acceptance in agriculture, ...
Toxicity assessment of TiO2 nanoparticles in zebrafish embryos under different exposure conditions
(Aquatic Toxicology, 2014-02-01) [Artigo]
The popularity of TiO2 nanoparticles (nano-TiO2) lies in their wide range of nanotechnological applications, together with low toxicity. Meanwhile, recent studies have shown that the photocatalytic properties of this ...
