Abstract This study aimed to formulate a milk protein concentrate (MPC) and evaluate the effect of this MPC supplementation on body composition, lipid profile, and product acceptability in resistance training (RT) practitioners. The physical, chemical and sensory properties were then analyzed. To evaluate the effect of the MPC supplementation on resistance training practitioners, 30 males were divided into two groups: a control group and an intervention group. Then the participants in the intervention group were supplemented with 500 mL of the MPC (250 mL pre-RT and 250 mL post-RT). Body composition (weight, height, and skinfolds) and biochemical markers (cholesterol and triglycerides) were measured at baseline and at 30, 60, and 90 days after treatment. Body composition results showed that the MPC supplementation during a RT program significantly (p < 0.05) reduced body fat percentage and fat mass, and increased lean mass in RT practitioners. Characterization of the MPC revealed low fat (3.32 ± 0.08%) and carbohydrates (4.58 ± 0.59%), and high protein (18.51 ± 0.51%) concentrations. Additionally, the product showed satisfactory acceptability index (> 71%). Thus, the MPC supplementation contributed to reduction of fat percentage, fat mass, and increase of lean mass in RT practitioners, without lipid profile alterations.

RESUMO Objetivo: Verificar a associação entre a participação em atividade física (AF) e a agregação de comportamentos de risco à saúde (CRS) em adolescentes de ambos os sexos. Métodos: Estudo transversal com participação de 862 adolescentes (11 a 17 anos) matriculados em 14 escolas públicas, selecionadas aleatoriamente, da cidade de Curitiba, Paraná. Foram avaliados a participação em AF, o tempo em tela, o consumo de frutas, vegetais, cigarros e de bebidas alcoólicas por meio de questionários. Para a associação entre os níveis de participação em AF e a agregação dos CRS, foi utilizada a regressão logística multinominal com obtenção de razão de chances (RC) com intervalos de confiança de 95% (IC95%). Resultados: Os adolescentes com alta participação em AF apresentaram menores chances de agregação de 2-3 CRS (RC 0,38; IC95% 0,21-0,68; p<0,01) e 4-5 CRS (RC 0,29; IC95% 0,16-0,53; p<0,01). Meninos com alta participação em AF apresentaram menores chances de agregarem 2-3 CRS (RC 0,31; IC95% 0,13-0,75; p=0,01), e meninas, menores chances de agregação de 2-3 CRS (RC 0,41; IC95% 0,17-0,99; p=0,04) e 4-5 CRS (RC 0,25; IC95% 0,10-0,61; p<0,01). Conclusões: A alta participação em AF esteve inversamente associada com a agregação de CRS em adolescentes.

ABSTRACT Objective: To verify the association between participation in physical activity (PA) and the clustering of health risk behaviors (HRB) in adolescents of both genders. Methods: A cross-sectional study involving 862 adolescents (11 to 17 years old) enrolled in 14 randomly selected public schools from Curitiba, Paraná, Brazil. Participation in PA, screen time, consumption of fruit, vegetables, cigarettes and alcoholic beverages were the criteria evaluated. Multinomial logistic regression tested the association between participation in PA and clustering of HRB, and results are expressed Odds Ratio (OR) with 95% confidence intervals (95%CI). Results: Adolescents with high participation in PA had lower odds of clustering 2-3 HRB (OR 0.38, 95%CI 0.21-0.68; p<0.01) and 4-5 HRB (OR 0.29; 95%IC 0.16-0.53; p<0.01). Boys with high participation in PA had lower chances of clustering 2-3 HRB (OR 0.31, 95%CI 0.13-0.75; p=0.01), and girls had lower odds of clustering 2-3 HRB (OR 0.41; 95%CI 0.17-0.99; p=0.04) and 4-5 HRB (OR 0.25; 95%CI 0.10-0.61; p<0.01). Conclusions: High participation in PA was inversely associated with the clustering of HRB in adolescents.

Abstract Aim: This study aimed to evaluate the cluster of the five major modifiable risk factors for cardiovascular diseases (CVD) and their associated factors and to identify patterns of concurrency of modifiable obesogenic risk factors associated with overweight in Brazilian adolescents. Methods: A survey was conducted (2015) with 1,055 (boys, n = 475; girls, n = 580) high school (public and private schools) adolescents (14-20 years old) in a medium-sized city in Southeast Brazil. The observed prevalence ratio (O) for the expected (E) risk factors (smoking, alcohol, insufficient physical activity, sedentary behavior, and poor diet) greater than one (O/E > 1) was considered as a cluster. We use multinomial and binary logistic regressions (stratified by sex) in the analyzes. Results: Almost 30% of adolescents had three or more risk factors (no factor = 5.4%). The five risk factors tended to cluster in boys (O/E = 2.5; 95% CI = 1.6-3.5). In both sexes, smoking and alcohol consumption persisted in O/E > 1 ratio. Conclusions: Boys showed a consistent pattern of association for risk factors. Overweight was associated with pairs of obesogenic risk factors in both sexes. The results indicate the need for health interventions that consider the cluster and the simultaneity of risk factors for CVD among Brazilian youth.

O Distrito Ferro-Manganesífero Urandi-Caetité-Licínio de Almeida congrega um total de 35 minas de manganês, a maioria exaurida, e 1 mina de ferro, em atividade, cujas rochas hospedeiras dos minérios estão associadas com a Sequência MetavulcanossedimentarCaetité-Licínio de Almeida, de idade paleoproterozoica. Essas unidades encontram-se deformadas pelo Cinturão de Dobramentos e Cavalgamentos Serra do Espinhaço setentrional, na porção norte do Orógeno Araçuaí. Na mina Lagoa D'anta, foram identificadas intercalações de itabirito, cummingtonita xistos, mármore calcítico e manganodolomítico, rochas calcissilicáticas e carbonato-silicáticas, metabasalto anfibolítico, além de quartzo-jacobsita xisto, solo residual rico em manganês e brecha laterítica manganesífera. O arcabouço estrutural principal apresenta trend geral NE-SW, sendo constituído dominantemente por estruturas compressionais. Esse arcabouço está associado com a evolução de duas zonas de cisalhamento transpressionais destrais, de idade ediacarana, denominadas de Carrapato, a oeste, e São Timóteo, a leste. O arcabouço estrutural na mina Lagoa D'anta reflete um maior grau de encurtamento no setor sul do Cinturão de Dobramentos e Cavalgamentos Serra do Espinhaço setentrional, na porção norte do Orógeno Araçuaí. As estruturas dúcteis relacionadas com essas fases deformacionais foram geradas em condições de metamorfismo progressivo com temperatura mínima de 550°C. Estruturas stockwork de quartzo, calcita, epidoto, grunerita e magnetita truncam as estruturas dúcteis da mina. Fraturas foram os principais canais de circulação de água meteórica que culminou com a formação de um minério supergênico de alto teor na mina.

The Urandi-Caetité-Licínio de Almeida Iron-Manganese District encompasses a total of 35 manganese mines, most of which are already exhausted, and 1 currently active iron mine. The host rocks of these ores are associated with the Paleoproterozoic Caetité-Licínio de Almeida Metavolcanossedimentary Sequence. These units have been deformed by the northern Serra do Espinhaço Thrust and Fold Belt, in the northern section of the Araçuaí Orogen. Interbeddings of itabirite, cummingtonite schist, calcite and manganese-dolomitic marbles, calc-silicate and carbonate-silicate rocks, and amphibolitic metabasalt were found at the Lagoa D'anta mine, in addition to quartz-jacobsite schist, residual manganese-rich soil and manganese lateritic breccia. The main structural framework presents a general NE-SW trend and it consists predominantly of compressional structures. This structural framework is associated with the evolution of two Ediacaran dextral transpressional shear zones, the Carrapato zone, in the western portion, and São Timóteo zone, in the eastern portion. The structural framework of the Lagoa D'anta mine reflects a higher degree of shortening in the southern sector of the northern Serra do Espinhaço Thrust and Fold Belt, in the northern area of the Araçuaí Orogen. The ductile structures related to these deformational phases were nucleated under conditions of progressive metamorphism with minimum temperature of 550°C. Stockwork structures of quartz, calcite, epidote, grunerite and magnetite truncate the mine's ductile structures. Fractures were the main circulation channels for meteoric water, which culminated in the formation of a high-content supergene ore in the mine.

Tiquira is a traditional homemade alcoholic distillate produced in the Maranhão State (Brazil), gotten from cassava (Manihot esculenta, Crantz.). It can be normally found on street markets. Due to the addition of tangerine leaves, the original tiquira has a bluish color. Samples of this beverage were acquired in the local trade and analyzed from the spectroanalytical point of view. The results indicated that these drinks had been adulterated by the addition of crystal violet, a potencialy hazardous compound. The identification and quantification of crystal violet in 10 spiked samples was accomplished by UV-Vis spectrophotometry through the standard addition method. In order to verify the efficiency of the proposed method, experiments on the quantification and recovery were carried out and the results indicated a content of crystal violet in the 10-6 to 10-7 mol L-1 range.
