title: Physical-chemical and biochemical characterization of Buchenavia tomentosa Eichler fruits

description: Abstract The wild native species of the Brazilian savannah have attractive flavors and nutritive compounds. Among the Combretaceaes genus, the Buchenavia tomentosa Eichler plays an important role in popular medicine, however, little is known about its chemical composition. Thus, in order to a chemical-biological prospection in fruits of the Tocantins savannah, the aim of this work was to characterize the B. tomentosa fruits collected in the central and southern regions of Tocantins State, about some of its physical, physical-chemical and biochemical properties. The fruits, for this study, were collected in two regions (Palmas and Gurupi) in Tocantins State and analyzed in the parameters: coloration, centesimal composition, pectin, soluble solids, pH and acidity, vitamin C content and phenolic compounds. The study obtained results demonstrate that the fruits are of a light yellow color, are acidic, have high values of °Brix and glycidic fraction (carbohydrates). However, the high levels of vitamin C (1.26 to 3.57 g ascorbic acid per 100 g of pulp) and phenolic compounds (2.93 to 4.20 g GAE 100 g-1) are noteworthy. This study evidences a great nutritional potential for the fruits of B. tomentosa.

title: EVALUATION OF THE RESULTS OF PELVIC FIXATION IN LONG LUMBOSACRAL INSTRUMENTATIONS IN ELDERLY PATIENTS

description: ABSTRACT Objective: Evaluate the initial results and the possible complications of the combination of pelvic fixation using iliac screws in long instrumentations of the lumbar spine in elderly patients. Methods: An analysis of 38 patients who underwent lumbar spine arthrodesis instrumentation with more than 3 levels, in which we included level L5-S1 and extended the fixation to the iliac crest. Radiological assessment of instrumentation through X-ray of the lumbar spine and pelvis, and computed tomography, to investigate the presence of radiological fusion. Clinical evaluation through a questionnaire of buttock pain including the visual analogue pain score (VAS). Complications related to pelvic instrumentation were investigated. Results: All patients had radiological fusion in the lumbosacral transition. A halo was found around the iliac screw on imaging studies in 31% of patients, but without related symptoms. The questionnaire of buttock pain found that 15% of patients had some low intensity buttock pain (VAS 1-2) and no need to or interest in removing the screws. There was infection at the surgical site in 2% of cases, hematoma in the buttocks in 5%, and vertebral body fracture in the cranial level instrumented in 7% of cases. Conclusions: Pelvic fixation through the iliac screws proved to be effective in protecting the S1 screws in long instrumentations including the L5-S1 level in elderly patients, allowing the radiological bone fusion. The overall results for pain were satisfactory, based on a questionnaire of buttock pain. There are no signs of overload or degeneration of the sacroiliac joints in the early years after surgery. Level of Evidence IV; Case series - therapeutic study.

title: Modeling of stem form and volume through machine learning

description: Abstract Taper functions and volume equations are essential for estimation of the individual volume, which have consolidated theory. On the other hand, mathematical innovation is dynamic, and may improve the forestry modeling. The objective was analyzing the accuracy of machine learning (ML) techniques in relation to a volumetric model and a taper function for acácia negra. We used cubing data, and fit equations with Schumacher and Hall volumetric model and with Hradetzky taper function, compared to the algorithms: k nearest neighbor (k-NN), Random Forest (RF) and Artificial Neural Networks (ANN) for estimation of total volume and diameter to the relative height. Models were ranked according to error statistics, as well as their dispersion was verified. Schumacher and Hall model and ANN showed the best results for volume estimation as function of dap and height. Machine learning methods were more accurate than the Hradetzky polynomial for tree form estimations. ML models have proven to be appropriate as an alternative to traditional modeling applications in forestry measurement, however, its application must be careful because fit-based overtraining is likely.

title: Physiology and quality of 'Tahiti' acid lime coated with nanocellulose-based nanocomposites

description: Abstract The aim of this study was to evaluate the physiological response and quality of the ‘Tahiti’ acid lime coated with carboxymethylcellulose (N-CMC), pectin (N-PEC) and starch (N-ST) nanocomposites based on cellulose nanocrystals (NC). Respiratory rate, ethylene production, loss of fresh weight, total chlorophyll and fruit firmness were evaluated during 9 days of storage. At the end of storage, only fruits coated with N-CMC and N-PEC exhibited significantly lower ethylene yield (0.92 and 0.98 μg C2H4 kg-1 h-1, respectively) than fruits coated with CMC and PEC (1.6 and 2.02 μg C2H4 kg-1 h-1, respectively). On the 3rd day of storage, fruits coated with N-PEC showed a respiratory rate (12.01 mg CO2 kg-1 h-1) similar to the fruits of the control (13.52 mg CO2 kg-1 h-1), but it was significantly lower than the fruits coated with PEC (14.93 mg CO2 kg-1 h-1). Only fruits coated with N-PEC showed significantly lower fresh weight losses than the control fruits. Fruits coated with N-PEC had chlorophyll retention levels (18.95 mg g-1) higher than fruits with PEC (13.25 mg g-1). This work showed that the N-PEC nanocomposite, based on NC, was the coating that showed greater potential for preserving quality of the ‘Tahiti’ acid lime.

title: The influence of sowing dates on the oil content and fatty acid composition of standard, mid-oleic and high-oleic types of sunflower (Helianthus annuus L.)

description: Abstract This study aimed to determine the oil ratios and fatty acid compositions of sunflowers grown in the warm climate of the Çukurova region at different sowing dates. It was found that the crude fat ratios of standard, mid-oleic and high-oleic sunflower types were 42.57%, 39.35% and 39.07%, respectively. Crude oil ratios of high-oleic and mid-oleic sunflower types were significantly decreased (p&lt;0.05) at SD4 (sowing date 4, May 30th). The oleic acid contents in standard, mid-oleic and high-oleic sunflower types were found to be 60.08%, 74.35% and 88.1%, respectively. The oleic acid ratios of standard sunflower types were determined to be significantly lower at SD1 (April 15th) (p&lt;0.05). The results show that it is more appropriate to sow the sunflowers between SD1 and SD2 (15 April to 30 April) in terms of producing the required oil and oleic acid contents. Also, both oil ratios and fatty acid compositions can change according to the sowing dates.

title: Maldi-tof mass spectrometry for the identification and detection of antimicrobial activity of lactic acid bacteria isolated from local cheeses

description: Abstract In this study, 21 traditionally made cheeses were used. A total of 150 lactic acid bacteria (LAB) isolates were obtained from cheeses. 100 of them were identified at genus levels as Leunoconostoc (10), Lactobacillus (46) and Enterococcus (44) using biochemical tests. 71 strains were identified as Enterococcus durans (6), E. faecalis (18), E. faecium (24), E. italicus (2), Lb. brevis (1), Lb. paracasei (2), Lb. plantarum (1), Lactococcus lactis (3), Leuconostoc lactis (1), Leu. mesenteroides (11), and Streptococcus parauberis (2) at species levels using MALDI-TOF MS analysis. 10 of 100 isolates that showed antimicrobial activity were obtained from 21 samples of local cheeses. LAB strains were centrifuged to obtain supernatants in order to investigate two mechanisms. First, unprocessed supernatant was used to examine total antibacterial effect. Second, bacteriocins were obtained from LAB strains isolated using partial purification. The Kirby-Bauer Disk diffusion method was used to compare their antimicrobial activity against six pathogen. In conclusion, the bacteriocin produced from E. faecium shows higher antimicrobial activity than the others, and therefore, it can be used as a biological preservatives to extend shelf life.

title: VALIDATION OF A NEW CLINICAL SIGN OF LUMBAR FACET SYNDROME

description: ABSTRACT Objective: Facet joints are true synovial joints, which derive their nerve supply from the sinuvertebral or recurrent nerve of Luschka as well as the posterior primary division of the corresponding spinal nerve. Diagnosis of low-back pain originating in the facet joints is difficult, and has traditionally relied upon invasive tests. To aid in the clinical diagnosis of this condition, the senior author described a new clinical sign. The following research project was designed to test the utility of this sign in the diagnosis of lumbar facet joint pain. Methods: We conducted a prospective evaluation of patients suspected of having low back pain secondary to facet joint involvement (Lumbar Facet joint Pain Syndrome – LFPS) during a twelve month observation period; candidate patients were evaluated clinically using the new diagnostic sign, which was then compared to findings on radionuclide bone scans and diagnostic medial branch blocks. Contingency table analysis was performed to calculate the sensitivity, specificity, positive and negative predictive values and accuracy of the new clinical sign. Results: Contingency table analysis showed the following operating characteristics for the new diagnostic sign: Sensitivity: 70.37%, Specificity: 50%, Positive predictive value: 90.47%, Negative predictive value: 20% and accuracy 67.7%. Conclusions: Although the new clinical sign failed to show the same operating characteristics as the ones originally described, it has high sensitivity coupled with a good positive predictive value. We consider that although the sign by itself is not diagnostic of lumbar facet joint pain, its presence should alert the clinician to the diagnosis and the possibility of requiring additional testing.

title: DETERMINATION OF CADMIUM IN LOW-COST JEWELRY FROM CHINA

description: This study aimed to determine cadmium in low-cost jewelry from China. In the qualitative test the sulfide was used as precipitating agent. Due to the strong interference of copper in qualitative analysis, this element was removed by chemical reaction or electrolysis. This removal was of paramount importance for the qualitative analysis of Cd2+. Quantification of Cd2+ was performed by means of atomic absorption spectrometry. The concentration of Cd was ~ 30% (w/w) in one of the pieces. It is noteworthy that in a small universe of low-cost jewelry analyzed (four samples), such a high cadmium content found in one of them leads us to think that jewelry containing Cd are widespread among citizens. This work can be useful to approach the case study method for teaching Analytical Chemistry at the undergraduate level.

title: What is the importance of vaccine hesitancy in the drop of vaccination coverage in Brazil?

description: ABSTRACT The successful Programa Nacional de Imunizações do Brasil (Brazilian National Immunization Program) has been experiencing a major challenge with regard to vaccination coverage for children, which has been dropping. Several aspects are related, but certainly vaccine hesitancy has been strengthening itself as one of the main concerns of Brazilian public administrators and researchers. Vaccine hesitancy is the delay in acceptance or refusal despite having the recommended vaccines available in health services, being a phenomenon that varies over time, over location and over types of vaccines. Hesitant individuals are between the two poles of total acceptance and refusal of vaccination. Vaccine hesitancy is nothing new in European and North-American countries, and even in Brazil, it has been studied even if under another name. The drop of vaccination coverage observed from 2016 on reiterates the relevance of the theme, which must be better understood through scientific research.

title: Helminth metacommunity structure of wild rodents in a preserved area of the Atlantic Forest, Southeast Brazil

description: Abstract The helminth fauna and metacommunity structure of eight sympatric sigmodontine rodents were investigated at the Serra dos Órgãos National Park, an Atlantic Forest reserve located in the State of Rio de Janeiro, southeast Brazil. Rodents of the species Abrawayaomys ruschii, Akodon montensis, Blarinomys breviceps , Delomys dorsalis, Oligoryzomys flavescens, Oligoryzomys nigripes, Oxymycterus quaestor and Thaptomys nigrita were found infected with helminths. Akodon montensis presented the highest total helminth species richness, with six different species of helminths. The nematode Stilestrongylus lanfrediae was the most abundant and prevalent helminth species observed. The host-parasite network analysis showed little interactions among host species. Akodon montensis seems to act as a keystone-species in the rodent community. This species shared the nematodes Stilestrongylus aculeata with A. ruschii and Protospirura numidica criceticola with T. nigrita, and the cestode Rodentolepis akodontis with D. dorsalis. The congeners host species O. flavescens and O. nigripes shared the nematodes Guerrerostrongylus zetta and S. lanfrediae. The rodents B. breviceps and O. quaestor did not share any helminths with other hosts. The helminth metacommunity showed a random pattern on both infracommunity and component community levels, indicating different responses by each helminth species to the environmental gradient.

title: When is the Best Time for Corrective Surgery in Patients with Tetralogy of Fallot between 0 and 12 Months of Age?

description: Abstract Objective: To identify the best time for corrective surgery of tetralogy of Fallot (TF) in children aged 0-12 months and to report the most frequent complications during the first 3 years postoperatively. Methods: Systematic review of studies published between 2000 and 2017 on corrective surgery for TF. Articles were selected through search of electronic databases (PubMed, SciELO, Scopus, Lilacs, Google Scholar, and Cochrane). Length of stay in intensive care unit, duration of mechanical ventilation, and peri/postoperative complications were analyzed for data discussion and research interpretation. Conclusion: Definitive corrective surgery is the best alternative, and the earlier it is performed, the lower the occurrence of harmful effects and the greater the chances of cardiorespiratory recovery. This systematic review suggests that the best time to perform definitive corrective surgery for TF in the first year of life is during 3-6 months of age in children with no or mild symptoms. Children with severe symptoms should undergo surgery immediately.
