title: Hydroenvironmental characterization of springs

description: Abstract Springs consist of an upwelling of groundwater from which water flows. This water then forms the drainage network. The negative environmental impacts caused in any portion of the basin may affect the quantity and quality of water. This study characterized the springs of Itanguá watershed, Capão Bonito, SP, considering their types, their conservation status, and the presence of negative environmental impacts. As for the type, springs were classified as “point” or “diffuse” and, regarding conservation status, they were ranked as “excellent”, “good”, “fair”, “bad” and “very bad” based on macroscopic evaluation. Nineteen springs were identified and 15 visited; of these, nine were classified as “point”, and six as “diffuse.” With respect to conservation status, two springs were classified as “excellent”, 12 as “good”, and one as “fair”. The presence of exotic species was observed by macroscopic evaluation, such as animal (boar) and vegetation (Pinus spp.). The lack of vegetation in “permanent preservation areas” was the most frequently observed environmental impact found. The methods used were efficient as a first analysis of the situation of the springs and to provide information to support programs to improve water conservation in the Floresta Nacional de Capão Bonito, SP.

title: Dapagliflozin versus saxagliptin as add-on therapy in patients with type 2 diabetes inadequately controlled with metformin

description: ABSTRACT Objective: This analysis compared the efficacy and safety of the sodium-glucose cotransporter-2 (SGLT2) inhibitor, dapagliflozin, and the dipeptidyl peptidase-4 (DPP4) inhibitor, saxagliptin, both added on to metformin. Materials and methods: This was a post-hoc analysis from a double-blind, randomized, 24-week clinical trial (NCT01606007) of patients with type 2 diabetes (T2D) inadequately controlled with metformin. We compared the dapagliflozin 10 mg (n = 179) and saxagliptin 5 mg (n = 176) treatment arms. Results: Dapagliflozin showed significantly greater mean reductions versus saxagliptin in HbA1c (difference versus saxagliptin [95% CI]: −0.32% [-0.54, −0.10]; p &lt; 0.005), fasting plasma glucose (-0.98 [-1.42, −0.54] mmol/L; p &lt; 0.0001), body weight (-2.39 [-3.08, −1.71] kg; p &lt; 0.0001) and systolic blood pressure (SBP) (-3.89 [-6.15, −1.63] mmHg; p &lt; 0.001). More dapagliflozintreated than saxagliptin-treated patients achieved the composite endpoint of HbA1c reduction ≥ 0.5%, weight loss ≥ 2 kg, SBP reduction ≥ 2 mmHg and no major/minor hypoglycemia (24% versus 7%). No major events of hypoglycemia were reported. More patients on dapagliflozin (6%) versus saxagliptin (0.6%) experienced genital infections. Conclusion: Dapagliflozin demonstrated greater glycemic efficacy than saxagliptin with additional benefits on weight and SBP, and the safety profile was consistent with previous studies.

title: MAGNETIC SUSCEPTIBILITY AS INDICATOR OF SOIL QUALITY IN SUGARCANE FIELDS

description: ABSTRACT Sugarcane management practices (unburned cane - UC and burned cane - BC) interfere with dynamics of soil magnetic properties. This study focused on determining the potential of magnetic susceptibility as soil quality indicator in areas under sugarcane cultivation. The experiment area is on the limit between basalt from São Bento Group, Serra Geral Formation, and sandstone from Bauru Group - Adamantina Formation. Twenty soil samples were collected from two management areas (burned and unburned sugarcane prior to harvest) at a depth range of 0.0-0.2 m. Local soil was classified as eutroferric Red Latosol (Oxisol), with highly clayey texture. Chemical and physical properties, CO2 emissions and magnetic susceptibility (MS) in air-dried fine earth (MSADFE), total sand fraction (MSTS) and clay fraction (MSCF). The magnetic signature from MS was effective in identifying changes of physical, chemical and mineralogical traits in Latosols under burned and unburned sugarcane crop. The information provided here can guide further studies on the genesis of minerals with magnetic expression in environments and exposed to fire burning.

title: Ratio of seeds and sodium hypochlorite solution on the germination process of papaya seeds

description: Abstract: Sarcotesta, a mucilaginous layer found in papaya seeds, negatively affects the germination of papaya seeds and its removal has been manually performed. The use of sodium hypochlorite can be an alternative to manual removal of sarcotesta in papaya seeds. The objective of this study was to evaluate the effect of different active chlorine concentrations (0, 2, 4, 6 and 8%) during 24 hours of immersion, in different proportions (10:200, 50:200, 100:200, 200:200, 300:200, 400:200, 500:200 and 600:200) of seeds number and solution volume (mL) to identify the best combination for an effective remotion of sarcotesta to improve the germination process. Germination test and first count were performed. A completely randomized design with four replications was used. Regression analysis was performed for quantitative variables with significant effect by F-test at 5% probability. Papaya seeds immersion in the ratio of 10 seeds per 200 mL of NaOCl solution (10:200, i.e. 20 mL of solution per seed), at a 2% sodium hypochlorite concentration during 24 hours of imbibition, can be used as an alternative for sarcotesta remotion for freshly harvested papaya seeds, because besides the effective remotion of sarcotesta, this technique improves the germination process.

title: New record of Melocactus peruvianus (Cactaceae) and conservation status of the Melocactus genus in Ecuador

description: Abstract The globular cacti are the group of cacti that are most at risk of extinction in Continental Ecuador. Melocactus bellavistensis, is distributed in a dry inter-Andean valley in the province of Loja and is currently listed in the category of Deficient Data (DD) by the IUCN. The other species, M. peruvianus is known only in two confirmed localities in Huaquillas (El Oro), near the border with Peru and is considered extinct in Ecuador. A new record of M. peruvianus is reported in a small remnant of Espinar Litoral within the Arenillas Ecological Reserve. The distribution and occurrence probability for both species is analyzed, and the home range was estimated by the use of the polygon minimum convex method (PMC). We recommended a new assessment of the conservation status and two new types of categories are proposed for both species in Ecuador. Finally, several alternatives are presented for its conservation.

title: VEGETATIVE PROPAGATION OF Spondias tuberosa E Spondias dulcis WITH THE USE OF IMMERSION IN INDOLE ACETIC ACID

description: ABSTRACT The objective of this work was to evaluate the effect of six indole-3-acetic acid (IAA) concentrations and three immersion times in IAA solutions on the vegetative propagation of Spondias dulcis and Spondias tuberosa by stem cuttings. The experiment was conducted in a greenhouse, using a completely randomized design, with a 6×3 factorial arrangement consisting of six indole-3-acetic acid concentrations (0, 2, 4, 6, 8, and 10 g L-1) and three immersion times (8, 16, and 24 seconds), with ten cuttings of S. dulcis and S. tuberosa per plot, and three replications. Percentage of surviving cuttings, and percentage of rooted cuttings, number of leaf buds, number of roots per cutting, root length, and total fresh weight were evaluated at 180 days after planting. Data were subjected to analysis of variance by the F test and to regression analysis. Vegetative propagation from woody cuttings of S. dulcis is not viable to produce seedlings, thus, new studies on this technique for this species are needed. Vegetative propagation from woody cuttings of S. tuberosa is satisfactory, but with low efficiency for improvement and emergence of new shoots and roots; it is more effective when using a concentration of 10 g L-1 of indole-3-acetic acid and immersion time in the solution of 16 seconds.

title: In situ DNA fragmentation during the re-establishment of desiccation tolerance in germinated seeds of Cedrela fissilis Vell.

description: Abstract: Dehydration is a necessary procedure prior to exposing seeds to long term storage, but this is associated with metabolism-linked injury mediated by cell injury. In order to assess cellular alterations during re-establishment of desiccation tolerance (DT) in C. fissilis germinated seeds and their relation to DNA damage, we verified the occurrence of DNA fragmentation through the TUNEL test and its evidence through the cytological analyses. To re-establish DT, germinated seeds were incubated for 72 h in polyethylene glycol (PEG, -2.04 MPa) before dehydration in silica gel (at 10% moisture content) followed by rehydration. The moisture content changes during the reestablishment of the desiccation tolerance was accomplished. (DT)TdT-dUPT terminal nick-end labeling (TUNEL) was used to assess rates of cell death. TUNEL staining was performed using Click-iT-TUNEL Alexa Flour imaging assay. The TUNEL test showed a consistent DNA fragmentation in the 2 and 5 mm long radicles. Moreover, nuclear and chromosomal alterations were observed in the 5 mm meristematic root cell cycle, contributing to the identification of diagnostic markers of cell death.

title: The Brasiliano collage in South America: a review

description: Analysis of recent geological and geochronological data from the basement of the South American platform indicates that the Brasiliano orogenic collage took place in four distinct pulses: a) Early Cryogenian (ca. 800 - 740Ma); b) Late Cryogenian-Early Ediacaran (ca. 660 - 610 Ma); c) Early-Middle Ediacaran (c. 590 - 560 Ma); and d) Late Cambrian (520 - 500 Ma). The first three pulses are well represented in most Neoproterozoic structural provinces in West Gondwana. The youngest orogenic phase/pulse, however, is only seen in Argentina (Pampean Orogeny) and Brazil, in eastern Rio de Janeiro State (Búzios Orogeny). The period between ca. 750 and 500 Ma is comparable to that reported for the amalgamation of various continental fragments in East (Arabian-Nubian, Mozambique, Kuunga) and North Gondwana (Cadomian). However, important differences in the nature and ages of events are recognized, which can be expected in view of the magnitude of Gondwana agglutination and the diversity of paleogeographic and tectonic scenarios. West Gondwana shows an interesting peculiarity: lithologically and tectonically diversified Tonian terranes underlie Brasiliano orogenic buildups. They were strongly reworked during most of the orogenic pulses. The Tonian terranes (1000 - 900 Ma) and their relation with Rodinia or with the processes of Gondwana fusion remains an open question. Indications of their presence in East Gondwana are still poorly documented.

title: Environmental Management of Larg Supply Chain: A Diagnostic Instrument Proposed for Assessing Suppliers

description: ABSTRACT This article addresses Supply Chain Management (SCM), focusing specifically on environmental management systems. A systematic review of the literature identified gaps in SCM studies and supported the development of a diagnostic tool model capable of measuring the level of involvement of suppliers in a Supply Chain (CS) with the Environmental Management program of a focal firm. The results of this study were synthesized in a diagnostic tool on which elaboration was based on the LARG SCM model, the Dynamic Capabilities model, and the Learning to Grow Methodology. The proposed model was structured to measure, through a graph, the level of involvement of the suppliers of an SC with the environmental management requirements based on ISO 14001: 2015. The model was tested on the supply chain of a company that was included in the ISE (2017) Corporate Sustainability Index and was validated by the surveyed company.
