Raman spectroscopy and multivariate curve resolution with correlation constraint were used for the identification and quantification of biofuels and adulterants in petroleum diesel. Firstly, quantification of two biofuels present in petroleum diesel (biodiesel and hydrotreated esters and fatty acids (HEFA)) was performed. The developed models for biodiesel and HEFA presented RMSEPs equal to 0.70%, indicating the practical application of the proposed methodology. Additionally, the identification and ...

A sociedade brasileira ainda não possui cultura favorável ao desenvolvimento de autoavaliação. Para superarmos a ideia de avaliação somativa e geradora de rankings com base em indicadores essencialmente quantitativos, faz-se necessário ousar e experimentar processos autônomos, formativos e com ampla participação da comunidade acadêmica em todos os níveis educacionais. Assim, diante do desafio de aperfeiçoamento da Avaliação Capes, especialmente em relação às limitações do emprego de métodos qualitativos ...

The antiproliferative effects of two azasterols, 22,26-azasterol (20-piperidin-2-yl-5α-pregnan-3β–20(R,S)-diol, AZA) and 24,25(R,S)-epiminolanosterol (EIL), in combination with sulphadiazine (SDZ) and pyrimethamine (PYR) were studied against Toxoplasma gondii tachyzoites growing in cultured mammalian cells. We had previously shown that AZA and EIL, two known inhibitors of Δ24(25)sterol methyl transferase in fungi and protozoa, have a potent and selective anti-T. gondii activity, although no 24-alkyl ...

We report potent and selective inhibitory effects of 22,26-azasterol and 24,25-(R,S)-epiminolanosterol, known inhibitors of Delta24(25)-sterol methyltranferase (SMT) in fungi and protozoa, on the proliferation of Toxoplasma gondii in LLCMK2 cells. These compounds produced a dose-dependent reduction in parasite proliferation. 22,26-azasterol had an IC50 of 5.3 microM after 24 h and 4.5 microM after 48 h, while for 24,25-(R,S)-epiminolanosterol the IC50 values were 1 microM after 24 h and 0.12 microM ...

The aim of the present study was to compare the modulation of heart rate in a group of postmenopausal women to that of a group of young women under resting conditions on the basis of R-R interval variability. Ten healthy postmenopausal women (mean +/- SD, 58.3 +/- 6.8 years) and 10 healthy young women (mean +/- SD, 21.6 +/- 0.82 years) were submitted to a control resting electrocardiogram (ECG) in the supine and sitting positions over a period of 6 min. The ECG was obtained from a one-channel heart monitor at the ...

Empowering students to report peer victimization is a major part of bullying intervention. Nevertheless, although bullying often can be discriminatory (e.g., homophobic), there remains limited attention to how issues of diversity relate to students reporting their victimization experiences. Among 572 students in four Chilean high schools, we tested a model in which multiple factors predicted students' consistency of reporting victimization. Students who perceived having a sexual orientation/gender ...

A insuficiência cardíaca (IC) com fração de ejeção preservada (ICFEP) é a forma mais prevalente de IC em pacientes com mais de 65 anos e representa mais de 50% dos casos prevalentes de IC na população. As intervenções terapêuticas da ICFEP ainda estão sendo exploradas e pesquisadas, como o uso de inibidores de SGLT-2. O presente estudo de revisão buscou avaliar novos avanços na abordagem terapêutica da insuficiência cardíaca com fração de ejeção preservada (ICFEP) a partir do uso de inibidores de SGLT- ...

Victimization based on actual or perceived sexual orientation or gender expression (SOGE) carries significant consequences. In this study, we examined how SOGE-based victimization and contextual factors predicted truancy among 886 Chilean students (Mage = 16.00, SD = 1.30) in four high schools. Victimization predicted truancy indirectly through its associations with students feeling unsafe at school—in general and specifically related to their SOGE. Furthermore, perceptions of a negative SOGE-based school ...

Objective: The progression of chronic kidney disease can directly affect patient's health-related quality of life (HRQoL). Exercise training is a good option to reverse the impacts caused by the disease. To escape from the monotonous routine and stimulate further practice, the therapist should consider making physical activity more playful. Using videogames during exercise training is possible to rehabilitate the patient aiming for fun beyond the organic condition. The present study aimed to evaluate ...

Zinc is an essential micronutrient for growth and development. Its deficiency causes growth retardation in children and adolescents. The present study analyzes the effect of zinc on growth hormone (GH) secretion, insulin-like growth factor 1 (IGF1), and insulin-like growth factor-binding protein 3 (IGFBP3) in normal children before puberty. Thirty normal children were studied, 15 boys and 15 girls, aged 6–9 years. They were orally supplemented with 5 mg Zn/day for 3 months and 0.06537 mg Zn/kg body ...

ABSTRACT Objective: The gait speed test (GST) is a physical test that can predict falls and aid in the diagnosis of sarcopenia in the elderly. However, to our knowledge, there have been no studies evaluating its reproducibility in hospitalized elderly patients. The objective of this study was to evaluate the safety and reproducibility of the six-meter GST (6GST) in hospitalized elderly patients. Methods: This repeated measures study involved hospitalized elderly patients (≥ 60 years of age) who underwent ...

The global population above 60 years has been growing exponentially in the last decades, which is accompanied by an increase in the prevalence of age-related chronic diseases, highlighting cardiovascular diseases (CVDs), such as hypertension, atherosclerosis, and heart failure. Aging is the main risk factor for these diseases. Such susceptibility to disease is explained, at least in part, by the increase of oxidative stress, in which it damages cellular components such as proteins, DNA, and lipids. ...

The generalized cross-correlation with phase transform (GCC-PHAT) algorithm has proved to be useful for blindly estimating the direction of arrival of compact sound sources from microphone array recordings. In applications with distributions of partial sources, such as the tires of vehicles in urban environments, the GCC-PHAT needs to be improved, otherwise the detected sound directions change values between directions of the main sources or correspond to an intermediate value between these directions. ...

The effect of physical activity counseling (PAC) in hypertensive adults is unclear. This study investigated the effect of PAC on blood pressure (BP), physical activity level, sitting time, metabolic profile, and body composition in hypertensive adults. Twenty-two hypertensive adults (48.8 ± 7.3 years) participated in this pilot trial. The 12-week PAC was based on the 5 A's model considering the FITT principle (Frequency, Intensity, Time, and Type) of physical activity. The control group received instructions ...
