title: THEORETICAL RESEARCH ON THE MULTI-CHANNEL REACTION MECHANISM AND KINETICS OF HNCS WITH OH-

description: We presented a theoretical study on the detailed reaction mechanism and kinetics of the HNCS molecule with the OH-. The barrierless minimum energy path and the most favorable entrance channel have been determined by study the thermodynamic and kinetic characters of the channel with low energy barrier. The B3LYP/6-311++G** method was employed for all the geometrical optimizations and a multi-level extrapolation method based on the G3 energies was employed for further energy refinements. In addition, the analysis of the combining interaction between hydroxide ion and HNCS was performed by natural bond orbitals (NBO) analysis. The calculation results indicated that the reaction of OH- with HNCS had four channels, and the channel of H-atom in HNCS direct extraction to OH- (OH-+HNCS→IM1→TS3→IM4→P2(SCN- +H2O)) in singlet state was the main channel with the low potential energy and high equilibrium constant and reaction rate constant. SCN- and H2O were main products.

title: Moderate physical training counterbalances harmful effects of low-protein diet on heart: metabolic, oxidative and morphological parameters

description: ABSTRACT Aims Maternal low-protein diet induces several impairments on cardiac system. Conversely, moderate exercise has been widely recommended to health improvement due to its effects on heart function. Thus, we investigated whether the moderate physical training is capable to offset the lasting injuries of a maternal protein restriction on the hearts of male adult rats. Methods Pregnant rats were divided into two groups: Control (C=17% casein) and undernutrition (U=8% casein). Offspring from the undernutrition group, at 60 days of life, were subdivided into undernutrition (U) and undernutrition+exercise (UT) groups. Treadmill exercise was performed: (8 weeks, 5 days/week, 60 min/day at 70% of VO2máx). 48 hours after last exercise session, tissues were collected for morphological and biochemical analysis. Results Despite the deleterious effect induced by low-protein diet, physical training was able to restore morphological parameters to similar levels to the control group. Additionally, oxidative stress index was also improved in UT group, due to the increase in antioxidant enzymatic defense. In metabolic enzymes, maternal low-protein diet induced a change in metabolism, and moderate physical training improved oxidative metabolism. Conclusion We demonstrated that moderate physical training can offset the cardiac metabolism in adult rats that were exposed to a maternal low-protein diet.

title: Psicodinâmica do trabalho e riscos de adoecimento no magistério superior

description: Abstract: The intensification of higher education teaching reflects a new paradigm of production and consumption of knowledge, in which demands characterized by the acceleration of activities, alienation and competitiveness coexist. In this sense, it is relevant to investigate the triad work/health/disease among college faculty. Therefore, we sought to analyze the critical indicators of illness at work, as perceived by the professors of the Federal University of Santa Maria (RS), by applying the Inventory on Work and Risk of Illness (Itra) and, later, semi-structured complementary interviews with faculty belonging to the knowledge areas with the highest participation. We identified serious cognitive overload among women (58%) compared to men, with evaluation in critical level (50%), as well as greater burnout, with evaluation in critical level (44%). The Mann-Whitney test revealed significant differences between men and women with regard to physical damage (p = 0.001), social harm (p = 0.01) and cognitive cost (p = 0.04). Thus, the role of gender should be considered as an element that promotes distinctions in perception, assessment and management of aspects involved in work and in vulnerability to risk of illness.

title: Dietary intake in high-level swimmers. A 32-week prospective cohort study

description: Abstract AIMS To determine whether high-level swimmers present adequate energy and macronutrient intake during each training phase of the season. METHODS A 32-week prospective cohort study was conducted with 18 elite swimmers (10 men, 20±2 years; 8 women, 20±3 years) from a competitive swimming club. This period comprised two training macrocycles, each one divided in four training phases: general, mixed, specific and competition. Dietary intake, estimated energy expenditure and daily energy requirements were assessed in every training phase. Body composition was evaluated five times throughout the season. Energy and macronutrient consumption were compared with the energy expenditure and the literature recommendations, respectively. RESULTS Athletes maintained a relatively constant dietary intake throughout the season, regardless the different needs of each training phase. The balance between energy consumption and expenditure was negative in all training phases (p=0.02; d between 1.5-6.2) for women, while men did so in half of phases (p&lt;0.01; d between 0.3-4.1). Swimmers had higher protein intake than recommendations in 73% of the evaluations, while carbohydrate and lipids intake were lower than recommendations in 76% and 69% of the evaluations, respectively. CONCLUSION Athletes did not meet the energy demands and specific macronutrient requirements of each training phase of the competitive season.

title: Assessing population-level morphometric variation of the Mountain Mullet Agonostomus monticola (Teleostei: Mugilidae) across its Middle American distribution

description: ABSTRACT Population-level morphometric variation of the Mountain Mullet (Agonostomus monticola) was assessed in 419 adult specimens from 25 sample sites (river basins) across its Middle American distribution (Pacific and Atlantic-Caribbean drainages). This analysis was based on 36 standardized linear measurements and 19 landmarks on geometric morphometrics approach. Discriminant function analysis (DFA) revealed 19 linear morphological characters with significant variation among groups. Geometrically, the most notable changes were associated to the curvature of the frontal region of the head, the anterior and posterior insertion of the first dorsal and anal fins. The resulting grouping based on the DFA and geometric morphometrics techniques (Pacific-A, Pacific-B and NE México-Caribbean) were similar to those previously recovered by genetic techniques, where the Pacific-B (Ayuquila river basin) was the most different group. Our results provide morphological evidence for considering Agonostomus monticola as a complex of evolutionary entities, represented by two forms in the Pacific Ocean and another in the Atlantic Ocean.

title: Acute effects of maximal isometric muscle action of the elbow extensors on contralateral dynamic task of the elbow flexors: a pilot study

description: ABSTRACT Aim the aim was to investigate the influence of a maximal isometric muscle action of the elbow extensors on the contralateral dynamic task of the elbow flexors. Methods Seventeen recreationally trained men (23.3 ± 4.9 yrs, BMI: 24.8 ± 2.2 Kg/m²) underwent two randomized different testing sessions separated by one week. In the control session (CON) all subjects performed a maximum number of repetitions test (RMs) at 75%1RM using the right elbow flexors. The experimental session (EXP) was similar to the CON; however, all subjects were instructed to perform RMs at 75%1RM by using the right elbow flexors and maintaining the maximal voluntary contraction of the left elbow extensors during the test. RMs, rating of perceived exertion (RPE), and training volume (TV) were measured and compared between sessions. Results The EXP showed a significant 10.4% increase on the RMs (13.8 vs. 12.5, p &lt; 0.001, d = 0.44) and 12.1% increase in TV (238.0 vs. 212.4 kg, p &lt; 0.001, d = 0.43) than CON. No differences were observed for RPE between sessions. Conclusion The maximum voluntary contraction of the left elbow extensors increased the RMs of the contralateral elbow flexors, reflecting a higher TV, and no differences in the RPE. Our results suggest that the investigated method may be a viable and practical alternative to increase the acute strength performance of elbow flexors when using submaximal loads.

title: USE OF THE ATOMIC ABSORPTION SPECTROMETER FOR THE DETERMINATION OF METHPHORMINE AND RANITIDINE CHLORIDRATES IN MEDICINES

description: The utilization of atomic absorption spectrometer for metformin (MET) and ranitidine (RAN) chlorohydrates determination in medicines is proposed. The spectral lines of nickel and aluminum at 232.0 and 308.2 nm were selected for MET and RAN absorbance monitoring, respectively. The results were compared to those obtained by molecular absorption spectrometry at ultraviolet range (spectrophotometry) and condutometric titration. The figures of merit obtained were adequate for MET and RAN determination in medicines. The limit of detection (LOD) of 0.01 mg L-1 obtained for MET and RAN, were similar and even lowers than those obtained by spectrophotometry and comparable with those found in the literature. The precision evaluated by relative standard deviation (RSD) was lower than 6%. The analytical application shows that in the analyzed samples the MET and RAN concentrations were in agreement with specified value in the label and the limits required by Brazilian legislation.

title: Vegetative development and content of calcium, potassium, and sodium in watermelon under salinity stress on organic substrates

description: Abstract: The objective of this work was to evaluate the vegetative development and determine the concentration of sodium, potassium, and calcium in watermelon (Citrullus lanatus) grown on two organic substrates and under increasing saline concentrations. The substrates were soil + earthworm humus (S1) and soil + bovine manure (S2), and the saline treatments consisted of irrigation water with different electrical conductivities: 1.36 (control), 3.56, 5.76, and 7.96 dS m-1. The experimental design used was a randomized complete block in a 2×4 (substrate × conductivity) factorial arrangement with five replicates. Main branch length, root length, stem diameter, leaf number, leaf area, and fresh matter mass of shoots and roots, as well as the sodium, potassium, and calcium contents in the plants, were determined. All phenological parameters showed interaction with the substrates, and S1 improved plant performance. Substrates interacted significantly with: leaf area; leaf number; stem diameter; main branch length; root length; fresh matter mass of shoots and roots; and the contents of sodium, potassium, and calcium, in both shoots and roots of watermelon irrigated with saline water for up to 27 days after emergence. There are also interactions between substrates and salinity for stem diameter, main branch length, fresh matter mass of roots, and calcium contents in both shoots and roots, and potassium and sodium contents in the roots.

title: Newborn's pain under the mother's perception

description: ABSTRACT BACKGROUND AND OBJECTIVES: Pain can generate important complications for the newborn. The mother, inserted in this context, becomes an important ally during the hospitalization since she stays with the. Thus, the study aimed to identify the mother's perception of pain in her hospitalized child in the Neonatal Intensive Care Unit and to compare the mothers' reports with a range of behavioral and physiological signs. METHODS: This is a qualitative study in a tertiary hospital in the State of Ceará. Fifteen mothers who were with their children hospitalized at the Neonatal Intensive Care Unit participated in the study, where they were placed in front of their children in two different moments: at rest and handling, in order to identify signs of pain. The data were analyzed by approximation of the speeches as proposed by Minayo. RESULTS: The results showed that the mothers did not perceive signs of pain in the newborn at rest. However, when handled, the mothers were able to identify the signs of pain through the characteristics presented in the newborn: facial expression, strong crying and the movement of arms and legs. CONCLUSION: Mothers are able to identify signs of pain in the child during painful procedures, mainly through crying and face changes. Thus, it points out the relevance of using pain evaluation scales to measure the behavioral and physiological signs of the newborn in a Neonatal Intensive Care Unit.
