Abstract: Aim: The aim is to compare the vocal fold vibration seen during lip and tongue trills with that seen during phonation of the sustained vowel /ε/, in terms of the periodicity of the EGG waveform and the amplitude of the EGG signal, in professional voice users. Study design: This was a quasi-experimental study. Methods: We used electroglottography (EGG) to compare the vocal fold vibration seen during tongue and lip trills with that seen during phonation of the sustained vowel /ε/, in terms of the EGG waveform periodicity and signal amplitude, in 10 classically trained, professional singers. The participants produced the sustained vowel /ε/ and performed tongue and lip trills at the same frequency and intensity. The periodicity of the waveform and the amplitude of the signal were visually analyzed by three blinded, experienced readers. To confirm the visual analysis results, we measured the jitter and shimmer of the signal and the frequency of variation in vocal fold vibration during the trill exercises. Results: The EGG waveform was classified as periodic for the sustained vowel phonation task and as quasi-periodic for the trill exercises, the vibration pattern repeating at approximately 24 Hz. Conclusion: The vibration of the vocal folds was modified according to the supraglottic movement in trills exercises.

Abstract: Introduction: The effects of voiced vibration technique can be assessed by laryngeal imaging. Kymographic images derived from high-speed videoendoscopy allow actual visualization of vocal folds vibration. Purpose: The aim of this study is to identify the immediate effects of the voiced vibration technique in healthy vocal folds using high-speed digital laryngeal imaging. Methods: Samples were obtained from 15 healthy subjects with no history of voice disorders (6 men and 9 women aged 21 to 43 years). High-speed videoendoscopy recordings were performed before and after the voiced vibration technique. Kymographic images were obtained using high-speed videoendoscopy. The vocal folds were examined in their open and closed positions and the characteristics of the opening and closing phases were determined. A customize computational routine was used quantify these parameters. The closing, opening, and speed quotients were also calculated. Results: In this study, women displayed statistically significant differences in opened phase (P= 0.05*), closed phase (P= 0.046*), and closing phase (P= 0.026*) phase characteristics. Men displayed the highest difference rate in opening time characteristics (P= 0.06). The closing and opening quotients for the female group showed significant differences (P= 0.029* and P= 0.049*, respectively). The speed quotient exhibited statistically significant differences in the male group (P= 0.048*). Conclusion: The kymographic images indicated that the immediate effect of the voiced vibration technique was smooth contact in healthy vocal fold vibration.

Abstract: purpose: to verify the efficacy of the values of the difference between the first two harmonics to distinguish adapted voices from slightly breathy (b) or tense (s), during the emission of the long vowel /é/. methods: thirty women with normal and altered voices were evaluated. each subject's vowel "é" was recorded in order to extract the intensity of the first two harmonics, using the fft graph. the range of the second harmonic was subtracted from the range of the first, and data were treated statistically. results: the variation between the values of h1-h2 between subjects rated 0 breathiness and tension and subjects rated 1, also in both parameters, was very high, therefore the values were not statistically significant. however, when the degrees of breathiness and tension get to 2, the variation values become more compatible with descriptions in literature. conclusion: the measure studied is not efficient to distinguish adapted voices from those slightly breathy and tense, during the emission of the long vowel /é/.

Abstract: The growth and expansion of economies of developing countries rely, in a great extension, on the access to financing sources for entrepreneur activities. Capital markets are one of the most efficient alternatives for local companies to have access to capitals, either local or foreign, and, therefore, for the boosting of the economic progress of such countries. In this sense, a legal framework of capital markets that fulfill the requirements of stability, certainty and security are essential in order to countries to compete for international capitals and investments. Indeed, such requirements are imperative to grow an environment of confidence of investors. Among other important issues in the capital markets regulation scope, there are two that have a vital importance to induce the confidence of investors and, consequently, to attract investment: the legal protection of investors and the regulation of the activities of credit rating agencies. It is vital that the legal system sets a framework for the protection of investors in the capital markets. The need of a stable, clear and secure framework does not imply an excessive intervention of the state in the ability of private economic agents to regulate their own interests. On the contrary, the state shall only provide for the minimum content of the financial services agreement and assure the compliance of the obligations taken under a contract. Furthermore, as the investment decisions made by economic agents rely mostly on the information they have on the financial instruments that are offered in the market, rules determining the full disclosure of information are essential. Concerning credit rating agencies, it is important to understand the role that such entities have undertaken in capital markets. Information about companies and financial instruments is the material economic agents use to make their investment decisions. But the cost to process and analyze the whole bunch of available data is too high for most agents, so they have to rely on the opinion of experts, such as credit rating agencies. In this context, regulation shall assure that the aforementioned agencies act in a fair and transparent way. Rules concerning conflict of interests, publicity of the criteria of rating analysis, and supervision on the activities of agencies are important to the growth of a sound capital market and an investment friendly environment. The article will focus on some of the production-centered jurisdictions—Argentina, Brazil, Chile, Colombia, Mexico, and Venezuela. They were chosen because they are the major

Abstract: Background Much attention has been drawn to the deleterious effects of adding progestins to estrogen as hormone therapy (HT) in postmenopausal women. Some widely prescribed progestins have been shown to partially oppose the beneficial effects of estrogens on surrogate markers of cardiovascular disease (CVD) risk. Progestins with higher androgenic activity may interfere with lipid profile and glucose tolerance, and could affect mechanisms of estrogen-induced C-reactive protein (CRP) stimulation. Recent data have shown that norpregnane derivatives, but not micronized progesterone, increase the risk of venous thromboembolism among transdermal estrogens users. The aim of the present study was to assess the effects of combining micronized progesterone with non-oral estrogen therapy on lipid profile and cardiovascular risk factors in a sample of early postmenopausal women. Methods Clinical trial including 40 women receiving intranasal 17β estradiol 3 mg/day for two months and 46 women receiving percutaneous 17β estradiol gel 1.5 mg/day for three months (E2). Both groups received an additional 200 mg/day of micronized progesterone by vaginal route 14 days/month (E2+P). Outcome measures included body weight, waist circumference, body mass index (BMI), lipid profile and ultra-sensitive C-reactive protein (usCRP) at baseline and during the E2 or E2+P portions of treatment. Results Mean age was 51±3 years. Mean time since menopause was 22.2±10 months. Most participants were overweight; HT did not change BMI. E2 and E2+P did not affect waist circumference and weight. Menopausal symptoms improved after HT. The effects of intranasal and percutaneous estradiol were similar, regardless of the addition of progesterone. Similarly, for the overall group of 86 women, micronized progesterone did not alter the response to E2. Blood pressure, glucose, insulin, HDL-c, triglycerides, and usCRP remained constant with or without micronized progesterone. Total cholesterol decreased after E2, and progesterone maintained this reduction. LDL-c levels were similar at baseline and with E2, and lower during E2+P in relation to baseline. Conclusions Cyclic, short term exposure to vaginal micronized progesterone did not alter the metabolic and cardiovascular effects of non-oral E2 in early, apparently healthy, postmenopausal women.
