1.  Plants with anti-Leishmania activity: Integrative review from 2000 to 2011 
Pharmacognosy Reviews  2013;7(13):34-41.
The search for more effective new drugs to treat Leishmaniasis is undoubtedly relevant. Our objective in this study was to investigate research publications addressing plants with anti-Leishmaniasis activity. An integrative review of the literature from 2000 to 2011 was carried out in the databases such as Latin-American and Caribbean Health Sciences (LILACS), Scientific Electronic Library Online (SciELO), and Medical Literature Analysis and Retrieval System Online (MEDLINE). In the initial search, 150 articles were found, with 25 based in LILACS, 68 in SciELO, and 46 in MEDLINE. From these data, after reading the abstracts that were available online, we excluded 12 from LILACS, 39 from SciELO, and 28 from MEDLINE for presenting article duplications. This left 61 articles to be read; however, only 18 of them answered the research questions and determined the final sample of this review. The results showed that research involving the search for new drugs against Leishmaniasis should be intensified, especially for the amastigote form, and studies with in vivo tests could become a great strategy for successfully finding new treatments for Leishmaniasis. It is believed that it is extremely important and urgent to conduct more trials in search of new effective drugs against Leishmaniasis that possess minimal adverse effects and that are easily accessible to the public.

2.  Brazilian solar saltworks - ancient uses and future possibilities 
Aquatic Biosystems  2012;8:8.
Coastal solar saltworks of Brazil are exploited for sea salt, which becomes progressively concentrated by evaporation. This study aimed to review the current and new potential uses of these systems, in order to provide more dynamic for this activity. The first evaporation ponds are also used for artisanal fisheries, ensuring the livelihood of many families. All the brine rich in secondary salts (bittern) can be widely used by the chemical industry, while the Brazil shows an incipient production of "flower of salt", a salt with distinct characteristics with higher market value than sodium chloride. On the other hand, the saltponds have a high potential for management and obtaining of large populations of Artemia spp., purifying the brine through the action as biological filter. This microcrustacean occurs naturally in intermediate salinity ponds, being commonly used in aquaculture. Species of microalgae and halobacteria found in the saltworks are employed for extraction of beta-carotene and glycerol, used in an extensive list of products with high commercial value. These ecosystems represent refuge zones for many species of migratory birds, becoming imperative to promote the conservation of these hypersaline wetlands.
