The northern of Mato Grosso has been suffering significant losses from its natural vegetation cover; context allied to the lack of an active environmental policy, besides the lack of knowledge of society about the importance of conservation and sustainable use of natural resources. In 2007, the professors of the Federal University of Mato Grosso (UFMT) created the Nucleus for Study of Mato Grosso Amazon Biodiversity (NEBAM), which aims at botanical and zoological studies related to the richness, diversity and distribution of Amazonian species and the Cerrado-Amazon transition environment. By generating their activities in a region subjected to intense anthropic pressure, NEBAM members have taken this guideline as a foundation for their development and, consequently, a contribution to regional knowledge. In addition, they participate in the formation of human resources and, through their extension projects, seek to contribute to the increase of environmental awareness, disseminating this accumulated knowledge, aiming at socialization and interaction with the community.

Climatic conditions in the mid-northern region of Mato Grosso State in Brazil are favorable for beekeeping. However, since 2011, the honey production chain has suffered losses because the production of off-odor honey has made it impossible to market the honey. Reports from beekeepers indicated a relationship between the off-odor in the honey and the nectar of Borreria verticillata (L.) G. Mey (Rubiaceae). In this study, the botanical origins and volatile profiles of ten off-odor honeys (H1-H10) and flowers of B. verticillata were evaluated. Palynological and sensorial analyses of the honeys were performed; a scale from 1 to 4 was applied for the sensorial analysis, in which 1 indicates no off-odor and 4 indicates extreme off-odor. Analysis of volatile was performed by using headspace solid-phase microextraction and gas chromatography-mass spectroscopy methods. The honeys investigated were classified with very high to intense off-odors, except H4 and H5, which did not differ from the control honey (no off-odor). Palynological analyses showed that honeys H1-H4, H7, and H9 were monofloral from B. verticillata, whereas in H5, H6, H8, and H10 this pollen were accessory. However, there was no quantitative correlation between the B. verticillata pollen content and the off-odor attributes of the honeys. Skatole was identified in all of the honeys except H4, H5, and the control honeys, suggesting that skatole contributed to the off-odor attributes of the products. However, further studies are required to investigate the origin of the skatole because it is not transferred directly from B. verticillata flowers to the honey. [ABSTRACT FROM AUTHOR]

We found six species of the genus Gurania that are described here as new records for the state of Mato Grosso, Central Brazil. The species of Gurania recorded here occur in the north of Mato Grosso state, Brazil in the biome recognized as "Floresta Amazônica". This is an area of southern Amazonia that has been poorly inventoried. We carried out the surveys in permanent plots using the RAPELD-PPBio system and along trails giving access to the permanent plots. [ABSTRACT FROM AUTHOR]

Cutaneous lesions lead to complications in patients, since they may be recurrent and also represent risk of progression to infection and/or amputation. Therefore, effective, protective, and topical treatments of easy application and removal need to be developed to provide effective alternatives to patients. The Caryocar brasiliense Cambess (CBC) presents important pharmacological activities and proved in the healing process. This paper reports the improvement of the CBC nanostructured (LNC CBC and LNC CBC+) activity in dermal wounds in vivo. The oil was physico-chemically characterized and used in the development of lipid-core nanocapsules (LNCs), coated (LNC CBC+) or without chitosan (LNC CBC), in concentration of 1.0 mg mL−1. Hydrogel (HG) was tested in vivo on lesions in the back of male Wistar rats for 14 days. The oil presented appropriate physico-chemical characteristics for its use, such as moisture 0.76 %, acidity 0.85 % and oleic acid 25.90 %. The LNCs showed nanometric size (around 200 nm), monomodal distribution, slight acid pH and zeta potential of + 22.1 mV in accordance with the composition. The nanostructured oil induced dermal healing in vivo showing significantly better improvement than free oil. LNC CBC+ showed best results showing the higher increase of the production of type 1 collagen, an important protein to the healing repair. These results suggest that development of formulations LNC CBC and LNC CBC+ are promising and important alternative for the treatment of dermal wounds, avoiding complications related to cutaneous lesions.
