Avaliação dos efeitos do cogumelo do sol (Agaricus blazei) sobre o colesterol plasmático em coelhos com hipercolesterolemia induzida

Prophylactic or therapeutic treatments administered with medicinal plants and natural products are used in popular medicine of diverse people since prehistoric times to the present days. Species with medicinal properties are increasingly studied in an attempt to understand their possible effects on organisms and their functioning. This study aimed to analyze the effect of the mushroom Agaricus blazei (aqueous extract) in rabbits subjected to experimental hypercholesterolemia. The animals were divided into two groups (control and treated with the mushroom) whose experimental protocol was divided into three phases: Phase 1, the animals were fed a normal diet to evaluate the physiological level of cholesterol; phase 2, the animals were fed a supplemented diet to induce hypercholesterolemia and in phase 3, the animals of control group continued to take high-cholesterol diet and the animals of treated group high-cholesterol diet including treatment with the mushroom. Weekly, after fasting of 14 hours, blood samples were collected from the animals and its plasma was stored for later measurement of plasmatic cholesterol. In the first phase, the cholesterol level was, on average, 31,30  7,34 mgdL-1. In the second phase, there was a significant increase (p<0,05) in cholesterol level of both groups. During the last phase of the experiment, the mushrooms didn’t cause reduction in plasmatic cholesterol of treated rabbits, however, prevent disease progression, maintaining the cholesterol level established at the beginning of treatment, whereas, in the control group, total serum cholesterol increased significantly at this stage

Implicações de um programa de formação continuada na formação e atuação de professores de educação física atuantes no ciclo I

This work focused on research a course of continuing education for teachers of Physical Education, offered in a city of São Paulo in 2013. Adopting as a benchmark analysis of models of continuing education in teaching, investigative question that guided this study was: what are the implications of this formative process in the formation and performance of the participating teachers?. With this guiding question, four were the objectives we seek to respond to this analysis: first identify the profile of teachers as well as the participation and involvement of the same course developed; 2 map and analyze the manifestations of teachers throughout the course; 3 reflect on the role of teachers in relation to approaches and/or distances with the common physical education curriculum proposed by the municipality; 4 identify and analyze the reflections on the course conducted. The methodological approach was qualitative and eighteen participants were teachers of a school system in a city of São Paulo, active in cycle I (1 to 5 years) of primary school. Data collection was carried out in two phases, with the participants in the first stage seventeen teachers and three teachers in the second stage that in addition to acting in the cycle I also actively participated in the course. Data were obtained in phase one using a diagnostic interview recorded on voice recorder and transcripts of observations and recorded in video and voice recorder from sixteen meetings of the continuing education course conducted in 2013 and phase two included the observation of classes teachers in the 2nd half of 2013, ending with a final interview. Demonstrations of physical education teachers in the course, as well as the situations observed and interviews indicated that on the profile of teachers are in the age range 30-58 years to serve at least five years in schools and most (10) does not work elsewhere. Another observation is that most of the participating teachers when thes...

Anti-erosive properties of solutions containing fluoride and different film-forming agents

Objectives: To evaluate the anti-erosive potential of solutions containing sodium fluoride (NaF, 225 ppm F) and different film-forming agents.Methods: In Phase 1, hydroxyapatite crystals were pre-treated with solutions containing NaF (F), linear sodium polyphosphate (LPP), sodium pyrophosphate tetrabasic (PP), sodium tripolyphosphate (STP), sodium caseinate (SC), bovine serum albumin (BSA), stannous chloride (Sn) and some combinations thereof. Deionized water was the control (C). The pH-stat method was used to evaluate hydroxyapatite dissolution. In Phase 2, the most effective solutions were tested in two independent experiments. Both consisted of an erosion-remineralization cycling model using enamel and dentine specimens with three solution treatments per day. In Phase 2a, the challenge was performed with 0.3% citric acid (pH = 3.8). In Phase 2b, 1% citric acid (pH = 2.4) was used. Hard tissue surface loss was determined profilometrically. Data were analyzed with two-way ANOVA and Tukey tests.Results: In Phase 1, F, LPP, Sn and some of their combinations caused the greatest reduction in hydroxyapatite dissolution. In Phase 2a, C showed the highest enamel loss, followed by LPP. There were no differences between all other groups. In Phase 2b: (F + LPP + Sn) < (F + LPP) = (F + Sn) < (F) = (LPP + Sn) < (LPP) < (Sn) < C. For dentine, in both experiments, only the fluoride-containing groups showed lower surface loss than C, except for LPP + Sn in 2a.Conclusions: F, Sn, LPP reduced enamel erosion, this effect was enhanced by their combination under highly erosive conditions. For dentine, the F-containing groups showed similar protective effect.Clinical significance: The addition of LPP and/or Sn can improve the fluoride solution protection against erosion of enamel but not of dentine.

Michelson interferometer vibrometer using self-correcting synthetic-heterodyne demodulation

Synthetic-heterodyne demodulation is a useful technique for dynamic displacement and velocity detection in interferometric sensors, as it can provide an output signal that is immune to interferometric drift. With the advent of cost-effective, high-speed real-time signal-processing systems and software, processing of the complex signals encountered in interferometry has become more feasible. In synthetic heterodyne, to obtain the actual dynamic displacement or vibration of the object under test requires knowledge of the interferometer visibility and also the argument of two Bessel functions. In this paper, a method is described for determining the former and setting the Bessel function argument to a set value, which ensures maximum sensitivity. Conventional synthetic-heterodyne demodulation requires the use of two in-phase local oscillators; however, the relative phase of these oscillators relative to the interferometric signal is unknown. It is shown that, by using two additional quadrature local oscillators, a demodulated signal can be obtained that is independent of this phase difference. The experimental interferometer is aMichelson configuration using a visible single-mode laser, whose current is sinusoidally modulated at a frequency of 20 kHz. The detected interferometer output is acquired using a 250 kHz analog-to-digital converter and processed in real time. The system is used to measure the displacement sensitivity frequency response and linearity of a piezoelectric mirror shifter over a range of 500 Hz to 10 kHz. The experimental results show good agreement with two data-obtained independent techniques: the signal coincidence and denominated n-commuted Pernick method.

Atividades de educação em saúde sobre leishmaniose visceral para escolares

This study aimed at evaluating the knowledge on visceral leishmaniasis gained after the application of an educative project for the 6th and 7th grade students from three public schools of Birigui, SP, Brazil. A questionnaire before (Phase I) and after (Phase II) activities that comprehended one conference by a health agent, a comic contest and one crossword about VL was used to measure scholar’s knowledge. We interviewed 711 students in Phase I and 693 in Phase II. A criterion of VL knowledge was adopted as “Good”, “Medium” and “Bad” when, out of 10 questions analyzed by Item Response Theory, 10 to 8, 7 to 4, and 3 to 0 were right, respectively. We observed a statistically significant increase in the students’ knowledge level after the educational project, since the number of students with “Good” concept changed from 35.7% (Phase I) to 59.7% (Phase II). The educational activities carried out led to gains in knowledge among students suggesting that continuing education can bring good results to public health.
