title: MOFs (METAL-ORGANIC FRAMEWORKS): A FASCINATING CLASS OF POROUS INORGANIC MATERIALS

description: Metal-Organic Frameworks (MOFs) are, according to IUPAC, coordination polymers with an open framework containing potential voids, which can be accessible after activation processes. These materials have aroused interest in the academic environment – and more recently in industry - because their properties such as high crystallinity, permanent microporosity, high surface areas, and the possibility of functionalization. This has enabled applications in different areas, such as gas adsorption, catalysis, drug delivery, photonics and others. Depending on the judicious choice of the metals and the organic linkers, MOFs with different topologies and functions can be created. Synthetic routes for the preparation of these materials will be discussed, highlighting those in consonance with the Green Inorganic Chemistry. Strategies for controlling the size and morphology of the crystals will also be presented, as well the most recent methodologies for the large-scale production. This review will also discuss the use of MOFs in the context of energy and environment, particularly referring to the adsorption and/or transformation of CO2, storage of H2 and CH4 as well potable water capture.

title: Phytochemistry and Allelophatic Potential of Torelliodora Eucalyptus Leaves on Germination and Initial Growth of Mutambo

description: ABSTRACT: Considering the possibility of a intercropping between exotic and native wood species for Legal Reserve areas restoration, information is needed about the possible interactions (positive or negative) between the involved species. The aim of this study was to determine the allelochemicals classes of aqueous extracts from dried and fresh leaves of torelliodora eucalyptus, as well as to evaluate the allelopathic potential of these extracts in the germination and initial growth of Guazuma ulmifola, a native species from Cerrado. To obtain the aqueous extracts at the concentrations of 25 mg mL-1, 50 mg mL-1, 100 mg mL-1 and 200 mg mL-1, the fresh and dried leaves of the eucalyptus were separately subjected to turbolize, followed by an ultrasound bath for two hours and static maceration, in darkness, for 48 hours in a refrigerator. The extracts were subjected to classical phytochemical analysis and determination of pH, electrical conductivity, soluble solids and allelopathic tests. For the germination and growth biological tests, a completely randomized experimental design with four replications per treatment was performed. The phytochemical analysis indicated that the phenolic compounds and derivatives are the major constituents of the aqueous extract of fresh and dried leaves of the tolleriodora eucalyptus, with predominance of the flavonoid contents on the dried leaves. Dried and fresh leaves extracts of torelliodora eucalyptus influenced G. ulmifolia germination, but this effect was dependent on their concentration. Initial seedling growth of G. ulmifolia was negatively influenced only by the dried leaves extract of the exotic species.

title: Weeds in Second Corn Crops in the Period of Transgenic Soybean Implantation in the Middle Paranapanema Region

description: ABSTRACT: The Middle Paranapanema region concentrates a large part of the second corn production in São Paulo State. Weed surveys in commercial areas are important for monitoring and directing their management. In 2006, 2007, and 2008, weed surveys were carried out on 27, 25, and 24 corn crops, respectively, in ten counties of this region. At the grain filling stage, crops were zigzag sampled with 20 points of 1 m2 per area. In addition, information on weed management, soil cover, and history of the summer crop were collected. The phytosociological parameters frequency, density, abundance, and importance value index were determined. The results evidenced Cenchrus echinathus as the most important species in 2006 and 2007, in addition to high importance values in 2008, which reflected the need to improve its management. Bidens pilosa, Digitaria horizontalis, and Euphorbia heterophylla were important species for the crop. Although under a low frequency, outbreaks of Leonurus sibiricus and Gnaphalium spicatum were observed in the areas, increasing their importance in 2007 and 2008. Atrazine was the most used herbicide over the agricultural years, with a low use of other products. Soil cover presented a high variation, but a high number of fields presented a low soil cover. Despite the increase of transgenic soybean in this region, no consistent evidence of changes in weed community resulted from this transition.

title: Weed Management in Rice under Sprinkler and Flood Irrigation Systems

description: ABSTRACT: This study aimed to assess the efficiency and selectivity of herbicides in rice submitted to sprinkler and flood irrigation systems. The experimental design was a randomized block design arranged in a 2 × 9 factorial scheme. Factor A consisted of irrigation systems (sprinkler and flood) and Factor B consisted of herbicide treatments (T1 - control; T2 - imazethapyr + imazapic, 75 + 25 g a.i. ha-1; T3 - imazethapyr + imazapic, 150 + 50 g a.i. ha-1; T4 - imazapic + imazapyr, 73.5 + 24.5 g a.i. ha-1; T5 - imazapic + imazapyr, 147 + 49 g a.i. ha-1; T6 - imazethapyr, 106 g a.i. ha-1; T7 - imazethapyr, 212 g a.i. ha-1; T8 - sequential application of imazethapyr + imazapic, 75 + 25 g a.i. ha-1; and T9 - sequential application of imazapic + imazapyr, 73.5 + 24.5 g a.i. ha-1). The application of imazethapyr and formulated mixtures of imazethapyr + imazapic and imazapyr + imazapic provided a control higher than 97% in flood and sprinkler irrigation systems. Herbicide selectivity is not altered in the sprinkler irrigation system when compared to the flood irrigation system.

title: Sorption-Desorption Behavior of Imazethapyr and Imazapic on Six Brazilian Soils

description: ABSTRACT: The characterization of sorption-desorption for imazethapyr and imazapic in six agricultural soils was performed to assess the availability of these herbicides in pollution processes. In this pursuit, the batch equilibrium method and high-performance liquid chromatography were used. The magnitude of Kf values ranging from 0.38 to 2.52 mg1-n kg-1 Ln for imazethapyr and 0.43 to 2.72 mg1-n kg-1 Ln for imazapic indicate weak sorption in the evaluated soils. Soil pH (5.1 to 6.1) and iron oxalate affect sorption-desorption of both herbicides but the type and percentage of clay can be the main factor affecting these two processes. A high desorption percentage (&gt;70%) was found in Regosol, Dystric Plinthosol, Ferralsol (for both herbicides), and Dystric Gleysol (only imazapic) soils, which implies in leaching risks of these imidazolinone herbicides into groundwater. Lower desorption (&lt;50%) was found in Cambisol and Alisol (for both herbicides), and (~50%) in Dystric Gleysol (only imazethapyr) soils, indicating that these herbicides could potentially injure the sensitive crops grown in rotation.

title: Sunflower protein concentrate and crambe protein concentrate in diets for silver catfish Rhamdia quelen (Quoy and Gaimard, 1824): use as sustainable ingredients

description: Abstract The objective of this study was to evaluate growth and metabolic parameters of silver catfish fed with protein concentrates of sunflower meal (SMPC) and crambe meal (CrMPC). The study evaluated two levels of substitution, where 25 or 50% of animal protein was replaced with plant-based protein. A total of 300 silver catfish (14 ± 0.26 g) were used in five treatments and three replications, in fifteen 280-liter experimental units. The results were submitted to analysis of variance and the means of the control diet was compared to the remaining treatments by Dunnett’s test at 5% significance level. At the end of the trial, no differences were observed for the variables final weight and daily weight gain. However, minor feed conversion was observed in the groups Control and SMPC-25%. Metabolic parameters were analyzed in the plasma and liver, where no significant differences were found for any of the blood parameters analyzed. In the analyzed liver parameters (ammonia, protein, amino acids and ALAT), the liver protein content was lower in fish consuming SMPC-50%, CrMPC-50% and 25% CrMPC diets. The amino acids content was higher in fish receiving the SMPC-25% diet. It can be concluded that sunflower meal protein concentrate is better utilized by fish and more efficient metabolically than crambe meal. This study demonstrated that a newly developed protein concentrate SMPC and CrMPC can effectively replace 25% and 50% the animal protein in a diet free of FM.

title: INTER SEASON PHYSIOLOGICAL CONTROL OF THE BRAZILIAN BEACH HANDBALL TEAM

description: ABSTRACT Introduction: The Brazilian national women's beach handball team traditionally holds intense pre-competition training with several daily sessions in the weeks before major matches. This can cause excessive physical strain, but physiological monitoring can guide the coaching staff to modulate the training load, preventing this excessive strain. Objective: To monitor the physiological responses of members of the Brazilian national women's beach handball team in a pre-competition training program with loads modulated according to individual physiological response. Methods: Seventeen athletes (27.1 ± 3.8 years) were assessed before the start of the pre-competition training period (E1), on Day 8 (E2) and Day 18 (E3). Blood samples were taken for subsequent analysis of muscular damage markers (creatine kinase (CK) and lactate dehydrogenase (LDH)). An ECG test was performed to assess cardiac autonomic modulation (CAM), and the Profile of Mood States (POMS) questionnaire was applied to assess mood. The results were reported to the coaching staff, who made training adjustments according to the individual status of each athlete. Results: CK increased significantly from E1 to E2 (131.1 ± 80.9 vs 212.9 ± 131.7) and remained unchanged (212.9 ± 185.6) up to E3, while LDH was significantly reduced from E2 to E3 (590.7 ± 120.2 vs 457.8 ± 86.6), finishing the pre-competition training program with values similar to E1 (512.7 ± 190.6). The only change noted was the subjective sensation of fatigue from the POMS questionnaire that was significantly higher in E2 (4.82 ± 4.05) and E3 (5.5 ± 4.8) compared to E1 (2.06 ± 2.61), but no changes in total mood disturbance were detected in this instrument. Conclusion: With the modulation of training loads based on results of physiological tests, the members of the Brazilian national women's beach handball team responded in a physiologically adequate manner, even when faced with a sudden increase in training load for 18 consecutive days. Level of evidence III; Diagnostic study-investigation of a diagnostic test.

title: COMPARISON OF THE EFFICACY OF LOSARTAN, HYDROCORTISONE AND ACETYLSALICYLIC ACID (ASA) IN PREVENTING THE DEVELOPMENT OF FIBROUS SCAR TISSUE IN SKELETAL MUSCLE

description: ABSTRACT Objective: To analyze fibrous scar tissue inhibition capacity with the use of losartan, hydrocortisone and acetylsalicylic acid. Method: The sample consisted of 120 male heterogeneic Wistar rats with a muscle laceration model. The rats were divided into four groups of 30 animals each: control group, losartan group, ASA group and hydrocortisone group. The animals were anesthetized and a 2.5 cm longitudinal incision was made in the left thoracolumbar paravertebral region. The muscles were subjected to a Grade III lesion caused by applying Kelly hemostatic forceps for 60 seconds, followed by sectioning with scissors. The skin was sutured with 3-0 nylon monofilament thread. The animals were placed in individual cages with plenty of food and water. The losartan group received losartan diluted in water at a dose of 0.1 mg/mL (10 mg/kg/day), the ASA Group received a 3 mg/mL ASA solution (300 mg/kg/day), and the hydrocortisone group received a 0.2 mg/mL hydrocortisone solution (20 mg/kg/day). Results: The control, losartan, hydrocortisone and aspirin groups had a fibrotic area of 0.95 ± 0.35 mm, 0.55 ± 0.34 mm, 0.93 ± 0.33 mm, and 0.66 ± 0.36 mm, respectively. We observed a significantly smaller fibrotic area in the losartan group compared to the control (p=0.01) and hydrocortisone (p=0.01) groups. There were no significant differences among the other groups. Conclusion: The healing of striated skeletal muscle produced less fibrous scar tissue when exposed to losartan in comparison to the control group or the hydrocortisone group. Level of Evidence I; Randomized double-blind placebo-controlled study.

title: COMPARISON OF AEROBIC POWER AND CAPACITY BETWEEN ATHLETES FROM DIFFERENT SPORTS

description: ABSTRACT Introduction: Ergospirometry is a noninvasive procedure used to assess physical performance or the capacity of an individual, through an analysis of expired gases and respiratory variables. This procedure is crucially important in sports, and makes a significant contribution to the measurement of cardiorespiratory fitness indices, such as maximal oxygen consumption (VO2 max) and the anaerobic threshold (AT). Objective: To assess aerobic capacity and potency in professional and junior soccer players, handball athletes, and women soccer players. Methods: Forty-eight athletes participated voluntarily and were divided into 4 groups. The first group consisted of 12 youth soccer players in the under-20 category, the second group was made up of 12 professional soccer players, the third group was made up of female soccer players, and the fourth group consisted of handball players. Results: We analyzed values such as peak VO2, average speed and heart rate at the anaerobic threshold as well as pulmonary ventilation. We found that the values were always greater for the group formed by professional soccer players, with the exception of mean maximum O2 consumption, in which the difference between this group and that of soccer players in the junior category was not significant. In other physical valences, there was a degree of similarity between the other groups, with special emphasis on pulmonary ventilation, which was significantly lower in the group of female soccer players. Conclusion: The particularities of each sport, such as pitch dimensions, duration, and tactical system, together with the morphology and sex of the athletes, directly influence peak VO2, AT and VE values in athletes who play different sports. Level of Evidence III; Development of diagnostic criteria in consecutive patients (with gold reference standard applied).
