title: Reassessing lipid metabolism and its potentialities in the prediction of cardiovascular risk

description: There are numerous particles, enzymes, and mechanisms in the lipid metabolism that are involved in the genesis of cardiovascular disease (CVD). Given its prevalence in populations and its impact on mortality, it is relevant to review the lipid metabolism as it may potentially provide subsidies to better prediction. This article reviews the importance of traditional cardiovascular risk factors and comments on the potential of novel lipid biomarkers involved in the physiopathology of CVD. The Framingham cohorts proved the role of traditional risk factors (physical inactivity, smoking, blood pressure, total cholesterol, LDL-C, HDL-C, plasma glucose) in the prediction of cardiovascular events. However, a significant number of individuals that suffer from a cardiovascular event has few or none of these factors. Such finding indicates the need for new biomarkers able to identify plaques that are more susceptible to rupture. Some of bloodstream biomarkers related to lipid metabolism are modified LDL particles, apolipoprotein AI (apo AI), apolipoprotein B, lipoprotein (a) [Lp (a)], cholesteryl ester transfer protein (CETP), subtypes of LDL and HDL particles, and lipoprotein-associated phospholipase A2 (Lp-PLA2). These factors participate in the atherosclerotic process, and are abnormal in individuals at high risk, or in those who suffered from a cardiovascular event. Lp (a) determination is already employed in clinical practice and should be included as a reference parameter for CVD monitoring. Furthermore, there are expectations for wider use of apo B, non-HDL cholesterol and total cholesterol / HDL-C determination to improve cardiovascular risk assessment.

title: Silent movies and the sound in Brazil (1894-1920)

description: Abstract The silent cinema has recurred to sound from its beginnings. Despite the importance of the connection between these two spheres, only recently foreign scholars began to study the uses the cinema made of sound. Here in Brazil, researches of this field are only beginning. This essay aims to recuperate the uses the silent movies made of sound in national ground, from the first experiences with the kinetoscope (in the ends of 1894) to the beginning of the 1920s, when the place of the music in the cinematographic spectacle was stabilized. From a transdisciplinary perspective, we intend to prove that the cinematographic scene from this period integrated a context of cultural circulation: when popular music and songs were used as accompaniment for the silent films; impregnating the cinematograph with former meanings, as well as constructing new meanings - ones that mixed the moving shadows of the artists to the social polyphony.

title: MOLECULAR PROFILE, PURITY AND PRESENCE OF TRYPSIN INHIBITORS IN COWPEA PROTEIN ISOLATES

description: ABSTRACT The most-used preparation process of protein isolates (PI) involves the isoelectric precipitation of the protein. Heating shortens the preparation time but this procedure may affect the purity, yield, molecular profile of the protein, and the activity of the trypsin inhibitor. This study aimed to investigate the effect of heating in the production of cowpea protein isolates. Crude whole beans (WB) were defatted with hexane, and the protein isolates obtained by isoelectric precipitation with (HPI), and without (NHPI) heating. The protein content of the WB and the PI was determined by the micro-Kjeldahl method, and the extraction yield estimated from the protein content at the end of extraction in relation to this content in the raw material. Possible losses of protein fractions were followed by SDS-PAGE, and the trypsin inhibitor activity determined by an enzymatic assay (BAPNA: benzoyl-DL-arginine-p-nitroanilide). Protein content in HPI was 83.3%, less than in the NHPI (92.2%). The HPI yield was lower (40.0%) as compared to the NHPI (42.3%). Electrophoresis indicated bands ranging from 13 to 262 kDa in WB; and the NHPI presented a protein fraction’s profile closer to that of the WB than to the HPI. The WB had the trypsin inhibitor activity, expressed as Trypsin Inhibitory Units (TIU), of 32.5±0.5 TIU /mg-protein; HPI showed 12.7±0.5 TIU /mg-protein (39% of that observed in WB) and the NHPI, 8.3±0.2 TIU /mg-protein (25.5%). Heating reduces the yield and purity of proteins in the isolates. However, the inhibitory activity of trypsin cowpea is most affected by the isolation procedure.

title: Ethics and morals: reflections of public health service dentists

description: Abstract This study aimed to analyze the ethical dimension experienced by dentists in the professional practice of a city in Rio Grande do Sul, Brazil, in order to contribute to the improvement of the work of these professionals. This is a qualitative study with content analysis. A semi-structured interview was used to collect data and eight dentist participated in the sample. The results show that there are flaws in the understanding of the Código de Ética Odontológico (Dentistry Code of Ethics) by most dentists, and little knowledge of professional ethics, leading to a lack of reflections on their daily practice. The study suggests that ethical flaws may be related to the content taught in the training of professionals in which the healing practice was predominant with focus on the technical aspects and little emphasis on knowledge aimed at humanization, prevention and health promotion.

title: Glycemic control and the production of cytokines in diabetic patients with chronic periodontal disease

description: Objective: To evaluate the association of glycemic control and cytokine production in type 2 diabetic subjects with chronic periodontitis. Methods: Gingival biopsies were performed in 40 patients, divided into four groups: systemically healthy subjects without periodontal disease (S); systemically healthy patients with chronic periodontitis (P); patients with well-controlled type 2 diabetes mellitus (DM) with chronic periodontitis (C); poorly controlled type 2 diabetes mellitus with chronic periodontitis (D). The production of interleukin (IL) -4, -6, -10, -17 and interferon (IFN) -g was quantified by ELISA. Results: The production of IL-4, IL-10, IL-17 and INF-g was higher on group D when compared to other groups (p &lt;0.05), which in turn were similar (p ³0.05). In addition, there was no difference in the production of IL-6 in any of the evaluated groups (p³0.05). Conclusion: Were observed significantly elevated levels of pro-inflammatory and anti-inflammatory cytokines in patients with poorly controlled type 2 diabetes and chronic periodontitis, demonstrating that glycemic control may be associated to the immune inflammatory response of sites with chronic periodontitis.

title: IDENTIFICATION AND QUANTIFICATION OF PHENOLIC COMPOUNDS AND ANTIOXIDANT ACTIVITY IN COWPEAS OF BRS XIQUEXIQUE CULTIVAR

description: ABSTRACT Cowpea (Vigna unguiculata [L.] Walp.) is one of the most important legumes produced in tropical and subtropical regions throughout the world, especially in the developing countries in Africa, Latin America, and Asia. It is the main source of protein, calories, dietary fiber, minerals, and vitamins for a large segment of the world population. Cowpea is also a potential functional food with a range of bioactive compounds, including phenolic compounds. This legume is grown mainly in the North and Northeast regions of Brazil, but is also consumed in other regions, and is thus important for the farmers who depend on this crop for income. This study identified and quantified phenolic compounds in the cowpea cultivar BRS Xiquexique. Such quantification reveals the functional characteristics of cowpeas, mainly as a source of antioxidants, which will be essential to add value to this food and to expand its forms of consumption. The extracts were analyzed using an HPLC model LC-20AT, equipped with a manual injector. For the HPLC analysis, standard solutions were prepared with pure phenolic acids such as gallic acid, quercetin, caffeic acid, chlorogenic acid, ferulic acid, p-coumaric acid, catechin, and epicatechin. The major phenolic compounds identified were catechin (2.07± 0.329 mg 100 g-1), epicatechin (0.48 ± 0.130 mg 100 g-1), gallic acid (67.19 ± 6.200 mg 100 g-1), ferulic acid (32.07 ± 0.753 mg 100 g-1), and chlorogenic acid (3.08 ± 0.489 mg 100 g-1). We observed that the BRS Xiquexique cultivar contains functional phenolic compounds, especially gallic acid and ferulic acid, demonstrating the antioxidant potential of cowpea.

title: Metabolic Syndrome and Insulin Resistance by HOMA-IR in Menopause

description: Abstract Background: Metabolic syndrome is an important cardiovascular risk factor, and its prevalence increases after menopause. However, it is still uncertain whether menopause is an independent risk factor for metabolic syndrome. One of the pathophysiological basis for metabolic syndrome is insulin resistance, which can be calculated by the Homeostatic Model Assessment-Insulin Resistance (HOMA-IR) method, and the association between insulin resistance and menopause is little known. Objective: To evaluate the association between metabolic syndrome and insulin resistance in menopausal women. Method: Descriptive study, which evaluated 150 women, aged 40 to 65, treated at a Gynecology Outpatient Clinic of a tertiary public hospital, from May to December of 2013. The sample was divided into two groups: Group I, comprising women in the premenopausal period and Group II, comprising women in the post-menopausal period. The presence of metabolic syndrome and its components were evaluated, as well as occurrence of insulin resistance in both groups. The association of menopausal status and the assessed variables was assessed using the Mann-Whitney, Chi-square and Fisher's exact tests. The significance level was set at 5%. The statistical analysis was performed using STATA 12.0. Results: Metabolic syndrome and its components were more prevalent in postmenopausal women. Postmenopausal women also had a higher prevalence of insulin resistance, but no statistical association was observed between the findings. Conclusion: The menopausal status was not significantly associated with metabolic syndrome and insulin resistance. Insulin resistance was considered an independent risk factor for the development of metabolic syndrome only in the postmenopausal group.

title: Esporte, economia e política: o automobilismo em Angola (1957-1975)

description: ABSTRACT This study aims to discuss the configuration of auto racing in Angola between 1957 (when the number of races started increasing) and 1975 (when the practice became extinct), seeking to understand its articulation with the political, economic and cultural aspects of the colony. To reach the goal, we have used newspapers and magazines as sources: Boletim Geral do Ultramar, Angola Desportiva and Revista de Automobilismo, Aviação e Turismo (ATCA). We argue that this research can enable us to understand Angola in its the last moments as a colony. In addition, we intend to take another step to understand the peculiarity of sports and amusements in colonial settings.

title: Additional Cardiac Remodeling Induced by Intense Military Training in Competitive Athletes

description: Abstract Background: Cardiac remodeling depends on the intensity, duration, and training method. Objective: To evaluate if the training performed in a Portuguese military special operations troop increases cardiac remodeling in a sample of young individuals who previously practiced competitive sports. Methods: A prospective study involving 76 military candidates for military special operations, 45 of whom previously practiced at competitive level (&gt; 10 hours per week). Of these military athletes, only 17 successfully completed the course. The evaluation was performed at 6 months intervals and included a complete clinical history, physical examination, vital signs, anthropometric data and echocardiographic evaluation. Statistical significance was considered when p &lt; 0.05, with a 95% confidence interval. Results: At the end of the course, there was a decrease in the percentage of fat mass (19.1 ± 3.3% vs. 13.1 ± 3.5%; p &lt; 0.01), an increase in the percentage of lean mass (41.3 ± 2.1% vs. 44.4 ± 1.8%; p &lt; 0.01), and decreased systolic and diastolic blood pressure and heart rate. Regarding cardiac remodeling, there was an increase in left ventricular diastolic diameter (49.7 ± 3.2 mm vs. 52.8 ± 3.4 mm; p &lt; 0.01), an increase trend in left atrial volume (27.3 ± 4.5 mL/m2 vs. 28.2 ± 4.1 mL/m2; p = 0.07) and increased left ventricular mass (93.1 ± 7.7 g/m2 vs. 100.2 ± 11.4 g/m2; p &lt; 0.01). Functional variables also changed, with an increase in S' (15 (13-16) cm/s vs. 17 (16-18) cm/s; p &lt; 0,01) and a decrease in left ventricular ejection fraction (60 ± 6% vs. 54 ± 6%; p &lt; 0.01). Conclusion: Intense military physical training resulted in additional cardiac remodeling in athletes of competitive level, both structural and functional.
