Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Commiphora leptophloeos (Mart.) J.B. Gillett (Burseraceae) is a medicinal plant native from the brazilian northeast caatinga biome, known popularly as "imburana" or "imburana-de-cambão". The leaves of C. leptophloeos are widely used in folk medicine in the treatment of various inflammatory disorders. However, there is no scientific evidence to justify their popular use. AIM OF THE STUDY This approach aimed to characterize the phytochemical profile of hydroethanolic leaf extract, as well as evaluate the anti-inflammatory and antioxidant potential activity and to investigate the acute toxicity with pre-clinical in vitro and in vivo methodologies. MATERIALS AND METHODS The phytochemical profile was characterized by UPLC-MS and FIA-ESI-IT-MS/MS. The in vitro anti-inflammatory potential the hydroethanolic extract of C. leptophloeos (1, 10, 100 and 200 μg/mL) was investigated by lipopolysaccharide (LPS) induced nitric oxide assay, in order to analyze the potential decrease of nitric oxide (NO) production. For carrageenan-induced paw edema and zymosan-induced air pouch models, the extract (100, 200 and 400 mg/kg) was administrated by intragastric gavage (i.g.) route and used for evaluating the anti-inflammatory effect in vivo. Related to the first animal model, the antiedematogenic activity and myeloperoxidase (MPO) levels could be investigated. In addition, the zymosan-induced air pouch model allowed the analyses of leukocytes migration, total MPO, malondialdehyde (MDA) and cytokines (TNF-α and IL-10) levels. The toxicity in vitro of the extract (1, 10, 100 and 200 μg/mL) was evaluated using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and acute toxicity in vivo was tested using the extract at 2000 mg/kg by i. g. route. RESULTS The phytochemical analyses of C. leptophloeos leaf extract pointed the presence of six glycosylated flavonoids, identified as orientin, isoorientin, vitexin and isovitexin, quercetrin and isoquercitrin. A decrease of NO in vitro was noticed by the use of the extract in the LPS-induced nitric oxide assay and an expressive reduction of the paw-edema followed by a decrease of myeloperoxidase activity at doses of 200 and 400 mg/kg. The zymosan-induced air pouch model indicated that the extract, in all doses, significantly reduced the leukocytes migration, total protein concentration, MPO and MDA levels. The levels of cytokines were verified by the administration of extract in this model, revealing a lower of TNF-α level and an increase of the IL-10 production. In the toxicity study, the MTT assay evidenced no cytotoxicity of the tested concentrations and acute toxicity in vivo test did not result in any sign of toxicity and mortality or significant changes on the biochemical parameters. CONCLUSION Based on these results, is possible suggest that the anti-inflammatory activity revealed in this approach can be related to the modulating the level of cytokine, decrease of TNF-α, increase of IL-10 in vivo and also the inhibition of the production of nitric oxide RAW 264.7 activated by LPS. These results demonstrate the potential anti-inflammatory effect C. leptophloeos leaf extrat in inflammatory in vivo models, supporting its use in folk medicine for treatment of inflammatory diseases. Finally, glycosylated flavonoids can be responsible, at least in part, for this effect.

Abstract
This study evaluated the antioxidant, antiproliferative, and immunostimulatory properties of cell wall α-d-mannan fractions from yeast Kluyveromyces marxianus CCT7735. Filter centrifugation was used to obtain four fractions (KMM-1, KMM-2, KMM-3, and KMM-4) with molecular weight ranging from 7.6 to 75.1kDa. KMM-1 and KMM-2 comprised D-mannose with traces of D-glucose, whereas other fractions contained only D-mannose. Total sugar found in samples ranged from 85.9% to 96.1%, while protein and phenolic contents were 1.21% and 0.41%, respectively. Although only KMM-1 was able to scavenge superoxide radicals, all fractions presented total antioxidant capacity as well as reducing power, hydroxyl-radical scavenging, and copper- and iron-chelating activities. No fraction was cytotoxic to HeLa cells. However, all samples inhibited the proliferation of the tumor cell Hep-G2 and presented minor cytotoxicity against normal 3T3 cells. All fractions showed mitogenic activity in macrophages and all, except KMM-4, induced nitric oxide production in macrophages, suggestive of their immunostimulatory effects.

Abstract
Physical, physicochemical, and microbiological changes were monitored in 256 samples of artisanal Minas cheese from eight producers from Serro region (Minas Gerais, Brazil) for 64 days of ripening to determine the minimum ripening time for the cheese to reach the safe microbiological limits established by Brazilian legislation. The cheeses were produced between dry season (April-September) and rainy season (October-March); 128 cheeses were ripened at room temperature (25 ± 4 °C), and 128 were ripened under refrigeration (8 ± 1 °C), as a control. No Listeria monocytogenes was found, but one cheese under refrigeration had Salmonella at first 15 days of ripening. However, after 22 days, the pathogen was not detected. Seventeen days was the minimum ripening time at room temperature to reduce at safe limits of total coliforms > 1000 cfu.g (-1) ), Escherichia coli and Staphylococcus aureus (> 100 cfu.g (-1) ) in both periods of manufacture. Otherwise under refrigeration, as expected, the minimum ripening time was longer, 33 days in the dry season and 63 days in the rainy season. To sum up, we suggest that the ripening of artisanal Minas cheese be done at room temperature, since this condition shortens the time needed to reach the microbiological quality that falls within the safety parameters required by Brazilian law, and at the same time maintain the appearance and flavor characteristics of this traditional cheese.

Abstract
The artisanal Minas cheese is produced from raw cow’s milk and wooden utensils were employed in its manufacture, which were replaced by other materials at the request of local laws. This substitution caused changes in the traditional characteristics of cheese. Due to the absence of scientific studies indicating the microbial composition of biofilms formed on wooden forms, tables and shelves used in these cheese production, the present work evaluated the counts of Staphylococcus aureus, Escherichia coli, coliforms at 32 °C, yeasts, presumptive mesophilic Lactobacillus spp. and Lactococcus spp. in these biofilms, milk, whey endogenous culture and ripened cheese in two traditional regions: Serro and Serra da Canastra. Also, we checked for the presence of Salmonella sp. and Listeria monocytogenes in the ripened cheeses. The ultra structure of the biofilms was also assessed. Counts above legislation (> 2 log cfu/mL) for the pathogens evaluated were found in milk samples from both regions. Only one shelf and one form from Serro were above limits proposed (5 cfu/cm2 for S. aureus and E. coli and 25 cfu/cm2 for coliforms) in this study for contaminants evaluated. In Canastra, few utensils presented safe counting of pathogens. There was no Salmonella sp. and Listeria monocytogenes in the cheeses after ripening. Thus, the quality of the cheese is related to improving the microbiological quality of milk, implementation and maintenance of good manufacturing practices, correct cleaning of wooden utensils, and not its replacement.
