title: WEIGHT-BEARING COMPUTED TOMOGRAPHY OF THE FOOT AND ANKLE: AN UPDATE AND FUTURE DIRECTIONS

description: ABSTRACT Spatial understanding of osteoarticular deformities of the foot and ankle is vital to correct diagnosis and therapeutic decision making. Poor reproducibility in conventional standing radiography in three orthogonal views has driven the development of weight-bearing computed tomography (WBCT) technology over the last decade. We analyzed the available literature on WBCT imaging in patients with foot and ankle disorders by performing a literature review of relevant clinical studies in multiple databases including PubMed, MedLine, and Scopus from January 1999 to October 2017. WBCT imaging allows correct evaluation of foot and ankle anatomy with the patient in a standing position, providing images with high spatial resolution, short image acquisition time, low dose of radiation, and costs which are similar to other available imaging technologies. This diagnostic tool can be used for decision making in the treatment of deformities of the ankle, hindfoot, midfoot, and forefoot. Level of Evidence III; Systematic review of level III studies.

title: Hydropriming as inducer of salinity tolerance in sunflower seeds

description: ABSTRACT Sunflower is a species with multiple potentialities and its yield can be affected by the presence of soluble salts in the soil, which is common in arid, semi-arid and irrigated regions. The objective of this study was to evaluate the effect of hydropriming as inducer of salinity tolerance in seeds and seedlings of sunflower, hybrid MG305CP. The germination tests were set with four replicates of 50 seeds per treatment, maintained in germinator at 30 ºC for ten days. To simulate salinity, sodium chloride diluted in distilled water was used at electrical conductivities of 0 (control), 4, 8, 12 and 16 dS m-1. On the tenth day, the number of normal seedlings was counted and the length and dry matter of shoots and roots were determined. Seedling fresh matter was used to determine the contents of total chlorophyll, total soluble sugars and proline. The experimental design was completely randomized, in a 2 x 5 factorial scheme (with and without hydropriming and five levels of salinity). Hydroprimed sunflower seeds showed greater vigor expression, with higher number of normal seedlings and faster germination.

title: FACTORS ASSOCIATED WITH THE DEVELOPMENT OF EARLY INFECTION AFTER SURGICAL TREATMENT OF FRACTURES

description: ABSTRACT Objective: Infection after the internal fixation of fractures is a major complication. Early infection is particularly challenging, because it occurs when the fracture is not yet united. The objective of this study is to identify possible factors related to the development of early infection in patients treated with internal fixation for fractures. Method: This retrospective observational study analyzed 24 patients with long bone fractures who underwent internal fixation and developed infections in the post-operatory period. The infections were classified as early (diagnosis in the first two weeks after surgery) or late (diagnosis after 2 weeks). Results: Of the 24 patients studied, 11 (46%) developed early infections and 13 (54%) were diagnosed with late infections. The early infection group was significantly younger (37.8 versus 53.1 [p = 0.05]) and underwent more surgeries prior to internal fixation (1.2 versus 0.2 [p &lt; 0.00]). Conclusion: Risk factors for the development of early infection in the postoperative period should be considered when treating patients with internal fracture fixation in order to diagnose this condition as early as possible. Level of Evidence IV; Case series.

title: Trajectory and technological dynamics of the machine tool industry in Brazil

description: Abstract The trajectory of the machine tool industry in Brazil from 1930 to 1980 is characterized by strong growth, although few firms in the industry accumulated technological capabilities in the process. If on one hand the market reserve generated demand growth, on the another it lead sectoral specialization in products with lower technological content. At present, the machine tool sector in Brazil has the ability to adapt international innovations to the internal market, and in these processes the creation and assimilation of knowledge with R&D, external licensing, interactions producer-user and access to knowledge of matrices in the case of branches of foreign companies take place.

title: Inoculum production and evaluation of temperature and leaf wetness for Passalora sojina inoculation in soybean

description: ABSTRACT The objective of this study was to develop a methodology for inoculum production and inoculation of Passalora sojina in soybean to assess the reaction to frogeye leaf spot. Thus, sporulation of fungal races was quantified in five substrates under two light regimes. The temperature and the leaf wetness period that resulted in greater infection efficiency were also determined. Petri dishes containing the culture media Oat Flour Agar (OFA), Tomato Juice (FTJ), V8 agar juice (V8), Infant Food (IF) and Potato Sucrose Agar (PSA) plus isolates of P. sojina races 23, 24 and 25 were subjected to 12-h photoperiod and 24-h continuous dark. Inoculated plants were incubated at temperatures of 15, 20, 25, 30 and 35 ºC and leaf wetness periods of 12, 24, 36, 48 and 72 hours. Experimental design was completely randomized with five replicates. There was interaction among isolate, culture medium and photoperiod. The highest sporulation (conidia/cm2) was obtained in the culture media FTJ (race 23) and V8 (races 24 and 25) under 12-h photoperiod. The optimum temperature for the disease development was 27oC under 72 hours of continuous leaf wetness.

title: Peixes da planície de inundação do alto rio Paraná e áreas adjacentes: revised, annotated and updated

description: ABSTRACT The book “Peixes da planície de inundação do alto rio Paraná e áreas adjacentes” represents the most cohesive data compilation for the rio Paraná floodplain. However, considering the dynamicity of the taxonomy of freshwater fishes, several new records and taxonomic changes occurred along the past years. Therefore, the results of that publication were revisited, providing an update of the species list, their taxonomic status, records and geographic distribution, and also new keys for genera and species. The species included were those recorded in the rio Paraná basin, from the mouth of the rio Paranapanema to the Itaipu Reservoir, following the general methodology presented in the book. A total of 10 orders, 41 families, 126 genera, and 211 species were registered, with an increase of one order, six families, 14 genera, and 29 species when compared to the book. Additionally, four new genera recently described, five synonymization proposals, 14 new identifications, four new combinations, 12 new species recently described, 34 new records, and nine misidentified species were recorded. These results are associated with the redirection of human and financial resources to that area, which enabled monitoring and intensive exploration of its watercourses; as well as training of taxonomists, and new taxonomic resolutions.

title: Effect of different bonding protocols on degree of monomer conversion and bond strength between orthodontic brackets and enamel

description: Abstract The objective of the present study was to evaluate the effect of different surface treatments and polymerization protocols on the bond strength of brackets to enamel, and the degree of conversion of the bonding agents. 120 bovine crowns were embedded in acrylic resin blocks and sanded. Next, the blocks were randomly assigned into 12 groups. Metal brackets were bonded to enamel according to the “surface treatment” factor (A: Phosphoric Acid; ATxt: Phosphoric Acid + Transbond XT Primer®; Tse: Transbond Plus Self Etching Primer®; and SBU: Scotchbond Universal®) and “polymerization” factor (R20: Radii-Cal®/20 seconds; V20: Valo Cordless®/20 seconds; and V3: Valo Cordless®/3 seconds). All samples were stored for 6 months (water, 37ºC) and then subjected to a shear bond strength test (SBS). Bond failures were classified according to the Adhesive Remnant Index (ARI) and analyzed with the Kruskal-Wallis and Mann-Whitney tests (5%). Using the same factors, 120 resin discs were made to assess the degree of conversion (DC) of the monomer. Data from the SBS (MPa) and DC (%) were analyzed by analysis of variance (2 factors) and Tukey’s test (5%). For the SBS, the factors “polymerization” (R20 = 8.1B; V20 = 13.2A; V3 = 5.2C, p = 0.0001) and “surface treatment” (A = 3.1C; ATxt = 13.6A; Tse = 12.3A; SBU = 6.3B, p = 0.0001) were statistically significant among groups. The highest adhesion value were found for the ATxt/V20 group (22.2A) and the lowest value for the A/R20 group (1.2E). Regarding ARI, score 2 was the most prevalent in groups A, ATxt, V20 and V3, while score 4 was the most prevalent in the Tse, SBU and R20 groups, with no significant difference between them (p = 1.0). Regarding DC, the factors “polymerization” (R20 = 66.6A; V20 = 58.4B; V3 = 45.1C, p = 0.0001) and “surface treatment” (A = 52B, ATxt = 59.7A, Tse = 51.4B, SBU = 63.8A, p = 0.0001) were statistically significant. Tse was more sensitive to the variations in polymerization protocols than the other surface treatments. Treatment A did not present suitable bond strength or degree of conversion.

title: Evaluation of soapberry (Sapindus saponaria L.) leaf extract against papaya anthracnose

description: ABSTRACT Chemical fungicides provide the primary means to control fungal infection in fruits and vegetables in the postharvest. Exploitation of natural products to control decay and prolong the storage life of perishables has received more attention. In this study, hydroethanolic extracts from the leaves of soapberry (Sapindus saponaria L.) were investigated for their inhibitory activity against the fungus Colletotrichum gloeosporioides, the causal agent of anthracnose in papaya fruits. To evaluate the antifungal activity of the plant extract, the latter was incorporated into potato-dextrose-agar (PDA) medium at different concentrations (10, 50 and 100 mg mL-1), and mycelial growth inhibition, spore production inhibition and morphological changes were evaluated at room temperature after 7 days. Efficacy of the extract was noted when it was used at 50 mg mL-1 and 100 mg mL-1, resulting in a reduction in the mycelial growth (P&lt; 0.05). At 50 mg mL-1, the extract causes morphological changes by reducing the size of hyphae, which become shorter and more branched. At 100 mg mL-1 extract, damages in the hyphal structure were more severe, causing mycelial rupture. In vivo treatment with 100 mg mL-1 extract prevented the development of anthracnose symptoms in fresh papaya fruits. Soapberry leaf extract has strong inhibitory activity against C. gloeosporioides, preventing the mycelial growth and reducing the appearance of anthracnose symptoms. Taken together, these results demonstrated the potential of this extract as a natural fungicide, constituting an alternative measure for disease control in papaya fruits.
