Cuiaba, Brazil

The Federal University of Mato Grosso was created in 1970. Located in the capital city of Cuiabá, it serves the entire state of Mato Grosso, Brazil. Teaching, research and extension programs are concentrated in 12 graduate programs, 63 undergraduate courses and a variable number of diploma courses in life, social and exact science.

Carnosic acid (CA) is a phenolic diterpene isolated from Rosmarinus officinalis and exerts anti-inflammatory, antioxidant, and anticarcinogenic activities in different cell types. It has been reported that CA is able to cause protective effects on experimental models of neurodegeneration. However, the exact mechanism by which CA prevents neuronal degeneration remains to be better studied. We investigated here whether there is a role for CA as a neuroprotective agent in a paraquat (PQ) model of Parkinson's disease (PD) regarding cellular and mitochondrial-related redox parameters. SH-SY5Y cells were treated with CA for 12. h and were exposed to 100. μM PQ for 24. h. It was found that CA at different concentrations prevented the effects of PQ on cell viability and redox parameters. CA alleviated reactive oxygen and nitrogen species production elicited by PQ, as well as decreased the toxic effect on mitochondrial function. Inhibition of Pi3K/Akt pathway with LY294002 or silencing of Nrf2 expression partially blocked the reversal of redox impairment induced by CA. Therefore, CA activated Nrf2 through modulation of PI3K/Akt pathway resulting in increased levels of antioxidant enzymes and consequent neuroprotection. Thus, CA may be viewed as a potential neuroprotective agent to be used in cases of Parkinson's disease (PD). © 2015 Elsevier Ltd.

Carnosic acid (CA) and carnosol are the major diterpenes found in Rosmarinus officinalis (rosemary), a culinary spice. CA and carnosol account for over 90 % of its anti-oxidant activity in rosemary leaves. The diterpenes exert anti-oxidant, anti-inflammatory, and anti-carcinogenic activities, and present neuroprotective effects in both in vitro and in vivo experimental models. In some cases, CA exerted protective effects upon neuronal cells more intensely than resveratrol or sulforaphane. Therefore, CA and carnosol demonstrate a potential pharmacological role for rosemary diterpenes in ameliorating mammalian brain redox status, among other parameters, as for instance the modulation of neuroinflammation. The aim of this review is to discuss the biological effects of CA and carnosol on neuronal and glial cells with focus on the mechanism of action of such diterpenes. © 2015, Springer Science+Business Media New York.

The time evolution of the density fluctuation of a two-dimensional high-density ultrarelativistic-like electron gas is studied at the long wavelength and zero temperature limits. The model we consider is a reduced version of the relativistic Sawada model within the massless Dirac particles frame. Time correlation functions are exactly calculated through the recurrence relations method, and a dynamic equivalence between the ultrarelativistic-like and the nonrelativistic dense electron gas systems is stated by the present approach. © 2015, Jagellonian University.

Precision farming tools such as auto-guidance systems assembled on tractors and/or sugar cane harvester machines are being applied to decrease the costs involved with ethanol production. The purpose of this study was to evaluate the accuracy, the cane loss and the operational field efficiency achieved by an auto-guidance system used to guide a sugar cane harvester over the field when compared to a manually-guided machine. The field test was conducted with two treatments: auto-guidance versus manual guidance; and day versus night. Each treatment was replicated four times. Each position recorded represented a single sample, which was used to calculate the error between the planned and actual paths. It was concluded that the use of an auto-guidance system operating on a sugar cane harvester during the day and night periods increased the field pass-to-pass accuracy relative to the planned row track, but it is essential that the crop was planted using the system. The use of the auto-guidance system did not significantly decrease the sugar cane loss, once the crop was well cultivated. More long-term research needs to be done related to this issue. The operational field efficiency of the cane harvester was the same for both auto-guidance and manual steering systems. © 2011 Springer Science+Business Media, LLC.

The monogamy of entanglement is generally discussed using a bipartite entanglement measure as an upper bound. Here we discuss a new kind of monogamous relation where the upper bound is given by a multipartite measure of entanglement, the generalized concurrence. We show a monogamous equality involving the multipartite concurrence, all the bipartite concurrences, and the genuine tripartite entanglement for pure three-qubit systems. The result extends to mixed states in an inequality involving the generalized concurrence and all the bipartite concurrences. We provide a counterexample showing that the result cannot be extended for systems with more than three qubits. © 2013 American Physical Society.

Quantification of parasite density is an important component in the diagnosis of malaria infection. The accuracy of this estimation varies according to the method used. The aim of this study was to assess the agreement between the parasite density values obtained with the assumed value of 8,000 cells/μL and the automated WBC count. Moreover, the same comparative analysis was carried out for other assumed values of WBCs. The study was carried out in Brazil with 403 malaria patients who were infected in different endemic areas of the Brazilian Amazon. The use of a fixed WBC count of 8,000 cells/μL to quantify parasite density in malaria patients led to overestimated parasitemia and resulted in low reliability when compared to the automated WBC count. Assumed values ranging between 5,000 and 6,000 cells/μL, and 5,500 cells/μL in particular, showed higher reliability and more similar values of parasite density when compared between the 2 methods. The findings show that assumed WBC count of 5,500 cells/μL could lead to a more accurate estimation of parasite density for malaria patients in this endemic region.

A current goal in plasmonic science and technology is to figure out how to manage the relaxational dynamics of surface plasmons in graphene since its damping constitutes a hinder for the realization of graphene-based plasmonic devices. In this sense we believe it might be of interest to enlarge the knowledge on the dynamical class of two-dimensional plasmonic Dirac systems. According to the recurrence relations method, different systems are said to be dynamically equivalent if they have identical relaxation functions at all times, and such commonality may lead to deep connections between seemingly unrelated physical systems. We employ the recurrence relations approach to obtain relaxation and memory functions of density fluctuations and show that a two-dimensional plasmonic Dirac system at long wavelength and zero temperature belongs to the same dynamical class of standard two-dimensional electron gas and classical harmonic oscillator chain with an impurity mass. © 2015 American Physical Society.
