title: Analysis of the effectiveness of transepithelial crosslinking in patients with keratoconus

description: Abstract Objective: To evaluate the clinical results of Transepithelial Crosslinking (CXL) by analyzing its efficacy in patients with progressive keratoconus. Methods: Retrospective cross-sectional study with 49 eyes and 37 patients aged 10 to 50 years submitted to the CXL technique in 2017 at the Instituto Panamericano da Visão, in Goiânia, Goiás, Brazil. The Avedro KXL system was programmed in pulsed mode with interval (1/1 second), using 45 mW/cm² with 7.2 J and 0.25% riboflavin solution of Avedro with irradiated corneas for 8 minutes. Data were collected: sex, age, uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), astigmatism, pachymetry at the thinnest point and keratometric astigmatism in the preoperative and postoperative periods at 1, 6 and 12 months. The Kolmogorov-Smirnov, Pearson's Chi-square, Friedman, Dunnett, and the Spearman correlation were used. Results: Twenty-three patients (62.2%) were female and 14 (37.8%) male. The mean age was 27.89 ± 10.89 years. The UDVA and CDVA significantly improved in the preoperative period in relation to 1 month (p = 0.01) and (p &lt;0.001), 6 months (p &lt;0.001 both) and 12 months (p &lt;0.001 both). Astigmatism significantly reduced preoperatively in relation to 6 months (p = 0.02) and 12 months (p = 0.02). The pachymetry at the thinnest point remained constant in the period (p = 0.95). The difference between k2 and k1 (keratometric astigmatism) showed a significant reduction in the preoperative period in relation to 1 month (p = 0.01). Conclusion: The CXL technique was safe and effective in the treatment and stagnation of the disease in patients with progressive keratoconus.

title: Oral and photographic testimonials: reports of memories of cultural actions of Mobral in the sertaneja community

description: ABSTRACT This article is a review of a research carried out in the period from 2015 to 2018, in the backlands of Alagoas, focused on the actions developed in the Mobral Cultural Program, implemented by the Brazilian Movement of Literacy (Mobral), based on oral history, Alberti (2008) and Bosi (1994), focusing on interviews as well as the photograph of Cartier-Bresson (1971), Guran (2011) and Leite (1993). It aimed to present the memorialistic narratives from the mentioned sources of two subjects inserted in the context of the cultural activities of such Movement, arising from the inquiries: the presence of cultural actions encouraged by the cultural Mobral caused the valorization of the sertaneja popular culture? What are the meanings for the sertanejos regarding the cultural initiatives offered? The oral and visual sources brought new reflections about the place - Sertão Alagoano - and it made us realize the resignifications that were possible in a Movement with the dimension that Mobral had, by the epoch of the Civil-Military Dictatorship.

title: CHRONIC CONSUMPTION OF ALCOHOL ADVERSELY AFFECTS THE BONE OF YOUNG RATS

description: ABSTRACT Objective: To assess the effect of chronic alcohol consumption on the longitudinal growth of the tibia and bone quality parameters in young rats under an experimental setup. METHODS: The control (n=10) rats received only water. The ethanol (n=10) rats received ethyl alcohol at concentrations established in the protocol for the induction of chronic alcohol consumption. The blood samples were immediately collected via cardiac puncture and processed to evaluate the levels of alkaline phosphatase by automated spectrophotometry. Following blood sample collection, both tibias were dissected, and weighed; the tibial length was measured., and the samples were stored in a freezer for future analysis of the bone mineral content and mechanical resistance, known as maximal load and stiffness. RESULTS: Compromised bone health, with a 35.3% decrease in the serum alkaline phosphatase levels (p &lt; 0.01), a 10% decrease in the tibial mass (p &lt; 0.05), and a 5.3% decrease in the tibial length (p &lt; 0.0001) were noted. Furthermore, a 10% decrease in the bone mineral density was observed (p &lt; 0.01), which led to a 17.2% decrease in the maximum strength (p &lt; 0.01) and 22.6% decrease in stiffness (p &lt; 0.001). CONCLUSION: Chronic consumption of alcohol affected the bones of young rats, making them weaker and osteopenic. In addition, the long bones were shorter, suggesting interference with growth. Level of Evidence III, Case Control Study.

title: Effect of ultrasound on the functional and structural properties of hydrolysates of different bovine collagens

description: Abstract The ultrasound effect on functional and structural properties of hydrolysates of different bovine collagens (fibers, gelatines and hydrolysates) was evaluated. The enzymatically hydrolyzed samples (enzyme Alcalase®) with previous or simultaneous ultrasound treatment presented higher number of bands with shorter wavelengths (mid-FTIR). The ultrasound provided the samples with a higher hydrolysis degree and favored the antimicrobial activity, evidencing the advantages of its use in the process. Results revealed that higher hydrolysis degree does not always result in higher antioxidant activity. The use of ultrasound in the hydrolysis of these samples was seen to be effective, providing them with higher functionality and structural disruption.

title: Foliar application of zinc in the agronomic biofortification of arugula

description: Abstract Zinc deficiency affects one third of the population and a possible solution is the agronomic biofortification of vegetables. Due to the increased consumption of arugula, this vegetable has good potential of use; however, there are few researches on the subject. The objective of this study was to evaluate the effect of foliar zinc applications, at different times, on physiological, yield, nutritional, and biofortification parameters of the ‘Broad Leaf’ arugula. Three doses (0.5, 1, and 1.5 kg ha-1 Zn) were evaluated at five times (15; 20; 25; 15 and 20; and 15, 20 and 25 days after emergence) and a control treatment. It was observed that there was no effect of the application on the physiological variables, as well as on the height, leaf area, and fresh mass of aerial parts of the plant. Zn sprayings affected the N contents, while for Mn, P, Cu, and Fe, no significant effects were found. It was verified that with the application of 1.5 kg ha-1 Zn made at 25 days after emergence, a higher Zn content was obtained in the arugula leaves, representing an increase of 279% in relation to the control, showing the effectiveness of foliar zinc applications as an agronomic biofortification strategy for arugula.

title: Effect of added prebiotic (Isomalto-oligosaccharide) and Coating of Beads on the Survival of Microencapsulated Lactobacillus rhamnosus GG

description: Abstract The study aimed to encapsulate Lactobacillus rhamnosus GG (LGG) with the selected prebiotic, using co-extrusion technology with a poly-L-lysine (PLL) coating and evaluate probiotic survival in simulated gastrointestinal conditions. Selection of ideal prebiotic was conducted using inulin, fructo-oligosaccharide (FOS) and isomalto-oligosaccharide (IMO) and its optimal concentration to be incorporated in microencapsulation was determined. Microcapsules without coating (S1: no prebiotic and S3: with prebiotic) and with coating (S2: no prebiotic and S4: with prebiotic) produced were evaluated based on its physical properties and survival in simulated gastrointestinal environment. The IMO with a concentration of 3.0% (w/v) was selected due to its best effect in promoting growth of LGG after 24 h (8.63±0.07 log CFU/mL). The morphology analysis revealed that all microcapsules produced were spherical with a diameter ranging from 491.3 to 541.7 µm and microencapsulation efficiency ranged from 84.16 ±5.30% to 90.56±3.33%. The incorporation of IMO and coating with PLL improved the survival of LGG by 3% up to 52% after 2 h of incubation in simulated gastric digestion. Among all formulations, PLL coated microcapsules added with IMO was the most effective in protecting LGG during the first hour of simulated gastric digestion (6.52 log CFU/mL) with cell viability greater than the minimum recommended level of 106 CFU/mL.

title: Does the Glyphosate Treatment Interfere Negatively on RNA Integrity in Glyphosate-Resistant and -Sensitive Conyza bonariensis?

description: ABSTRACT: The hairy fleabane ( Conyza bonariensis (L.) Cronq.) is among the most problematic glyphosate-resistant weeds to manage around the world. In weed science, molecular approaches such as RNA sequencing (RNA-Seq) and quantitative reverse-transcription polymerase chain reaction (RT-qPCR) have been employed to study molecular responses to glyphosate treatment in Conyza species. Glyphosate treatment leads to reactive oxygen species (ROS) production in plants which could damage the RNA. Degraded RNA is an issue and can compromise further molecular analysis. Thus, the objective of this study was to evaluate whether glyphosate treatment interferes negatively on RNA integrity of glyphosate-resistant and -sensitive hairy fleabane biotypes. Two experiments were performed using glyphosate doses from 0 to 11,840 g a.e. ha-1 and evaluated in a time-course until 288 hours after treatment. The total of 86 RNA samples were evaluated. The RNA integrity was evaluated in a Bioanalyzer 2100 equipment according to RNA integrity number (RIN) scores and electrophoresis gel. The RIN scores ranged from 5.1 to 9.0. Glyphosate doses do not reduce the RIN scores in both glyphosate-resistant and -sensitive biotypes of hairy fleabane. Visual and automatic analysis of electrophoresis gel show suitable results for all RNA samples, with well-defined bands at 28S and 18S positions and no degradation. The results of the analysis indicate that glyphosate treatment does not affect the RNA integrity of glyphosate-resistant and -sensitive biotypes of hairy fleabane until 288 and 192 hours after glyphosate treatment, respectively. The RNA integrity analysis provides useful results to evaluate the RNA condition for further analysis. However, the costs were around US$ 14.25 per sample, considering only reagents. These results are useful for planning future time-course experiments in Conyza spp. after glyphosate treatment.

title: Dry fruit as source of fungal contaminants or functional compounds?

description: Abstract This study evaluated the role of dry fruits as a source of fungal contaminants or functional compounds. Dry apple, apricot, candied fruits, prune, and white and black raisin were evaluated regarding patulin and ergosterol content, centesimal composition, pH, acidity, pectin, and phenolic profile. The ergosterol was detected in 38% of the samples and patulin (PAT) in 89%, the apricot samples stood out most by contaminant level. Apricot, candied fruit, and prunes presented moisture values beyond the other dry fruits. The pH ranged from 3.8 to 4.6; acidity from 0.1 to 1.0%; sugar content from 1.7 to 5.5%; and levels of soluble and insoluble pectin from 1.6 to 5.1% and 10.9% to 27.3%, respectively. The apples showed a higher content of free phenolic compounds (6.6 mg of gallic acid/g) with a predominance of gallic and protocatechuic acids. Pearson's correlation showed a significant positive correlation between patulin and ergosterol content (0.99) and soluble pectin (0.78); a significant negative relation between total sugars (-0.66) and free phenolic compounds (-0.63). Fungal contamination and the occurrence of PAT show that this mycotoxin is present and, therefore, the evaluation of fungal toxins in dry fruits is recommended before claiming them to be a source of functional compounds.

title: Activity of polyphenoloxidase and peroxidase in non-dormant potato tubers treated with sprout suppressors

description: Abstract One of the major problems affecting potatoes quality on stored is the susceptibility to enzymatic browning, which occurs mainly after wounds during the harvest, at postharvest handling and by aging, leading to the development of dark color compounds. Enzymatic browning is associated with the action of polyphenoloxidases (PPO) and peroxidases (POD), which use phenolic compounds and oxygen as substrates. The products of these enzymes cause undesirable changes of color and flavor of processed potato products. The present study aimed to evaluate some kinetic properties based to optimum pH and reaction temperature, and to determine changes on activity of potato tubers PPO and POD treated with sprouting suppressors compounds menthol and eugenol. For each treatment, samples were collected in six different periods, before application (day 0) and 10, 20, 30, 40, and 50 days after the treatments to determine the influence of sprout inhibitors on the activity of PPO and POD. Changes in pH and temperature affected drastically the activity of both enzymes. The use of eugenol and menthol as sprouting suppressors decreased enzymatic activity on the treated tubers compared to control with an inverse relationship between enzymes activity and content of phenolic compounds.
