title: Effect of the roasting temperature and time of cocoa beans on the sensory characteristics and acceptability of chocolate

description: Abstract The aim of this work was to study the impact of the roasting temperature (80, 120 and 160 °C) and time (20, 40 and 60 min) of cocoa beans on the sensory acceptability of chocolate using response surface methodology. The results revealed that there was higher impact of roasting temperature and no influence of roasting time (in the studied levels). Lower score of consumers’ sensory acceptability was found at higher roasting temperature of cocoa beans (160 °C). The chocolate samples presented undesirable burnt odor and flavor. Roasting temperatures range 90 to 110 °C were found optimum for higher consumer’s acceptability scores (appearance, aroma, flavor, texture and overall quality attributes). Ten trained assessors consensually defined fifteen descriptors showing similarities and differences among the chocolate samples, using the methodology based on Quantitative Descriptive Analysis. The Principal Component Analysis showed that A, B and C treatments (80 °C) were characterized primarily by the brown color, sweet aroma and flavor attributes. The treatments D, E and F (120 °C) were characterized by reddish brown color, bitterness, burnt aroma and flavor, astringency attributes.

title: Unilateral extravesical ureteral reimplantation via inguinal incision for the correction of vesicoureteral reflux: a 10-year experience

description: ABSTRACT Introduction and Objective: Multiple options exist for the surgical management of vesicoureteral reflux (VUR). We report on our 10-year experience using the inguinal approach to extravesical ureteral reimplantation (EVR). Materials and Methods: Patient characteristics of age, gender, and reflux grade were obtained and outcomes of operative time, hospital stay, and radiographic resolution were assessed. Results: 71 girls and 20 boys with a mean age of 74 months (range 14-164) underwent inguinal EVR via a 3.5-cm inguinal mini-incision. Mean follow up was 10.9 months (range 0.4-69.7). Average grade of reflux was 2.80. Average operative time was 91 minutes (range 51-268). The procedure was successful in 87 of 91 patients (95.6%). The 3 cases of reflux that persisted were all grade 1 and managed expectantly. Contralateral reflux developed in 9 cases, all of which resolved after treatment with either Deflux or ureteral reimplant. There were 4 case of urinary retention that resolved after a brief period of CIC or indwelling catheterization. There were no cases of ureteral obstruction. Most patients were discharged on post-operative day 1 (85/91) and no hospitalization extended beyond 3 days. Conclusions: The inguinal approach to extravesical ureteral reimplantation should be considered as a potentially minimally invasive alternative to endoscopic and robotic treatment of VUR with a success rate more comparable to traditional open approaches. We feel it is the method of choice in cases of unilateral VUR requiring surgical correction.

title: Purification and characterization of a thermostable alkaline cellulase produced by Bacillus licheniformis 380 isolated from compost

description: ABSTRACT During composting processes, the degradation of organic waste is accomplished and driven by a succession of microbial populations exhibiting a broad range of functional competencies. A total of 183 bacteria, isolated from a composting process, were evaluated for cellulase activity at different temperatures (37, 50, 60, and 70°C) and pH values. Out of the 22 isolates that showed activity, isolate 380 showed the highest cellulase activity. Its ability to produce cellulase was evaluated in culture medium supplemented with carboxymethyl cellulose, microcrystalline cellulose, wheat straw, and rice husk. The culture medium supplemented with carboxymethyl cellulose induced higher enzyme activity after 6 hours of incubation (0.12 UEA mL-1 min-1). For wheat straw and rice husk, the results were 0.08 UEA mL-1 min-1 for both, while for microcrystalline cellulose, 0.04 UEA mL-1 min-1 were observed. The highest carboxymethyl cellulase activity was observed at 60°C (0.14 UEA mL-1 min-1) for both crude and partially purified enzyme after 30 and 120 min of incubation, respectively. Alkalinization of the medium was observed during cultivation in all substrates. The cellulase had a molecular mass of 20 kDa determined by SDS-Page. Isolate 380 was identified as Bacillus licheniformis. This work provides a basis for further studies on composting optimization.

title: Dipyridamole reduces penile apoptosis in a rat model of post-prostatectomy erectile dysfunction

description: ABSTRACT Purpose: Despite the nerve-sparing technique, many patients suffer from erectile dysfunction after radical prostatectomy (RP) due to cavernous nerve injury. The aim of this study was to evaluate dipyridamole as a potential treatment agent of post-radical prostatectomy erectile dysfunction. Material and methods: A total of 18 male Sprague-Dawley rats were randomized into three experimental Groups (SHAM+DMSO, BCNI+DMSO and BCNI+DIP). An animal model of bilateral cavernous nerve crush injury (BCNI) was established to mimic the partial nerve damage during nerve-sparing RP. After creating of BCNI, dimethyl sulphoxide (DMSO) was administered transperitoneally as a vehicle to SHAM+DMSO and BCNI+DMSO Groups. BCNI+DIP Group received dipyiridamole (10mg/kg/day) as a solution in DMSO for 15 days. Afterwards, rats were evaluated for in vivo erectile response to cavernous nerve stimulation. Penile tissues were also analyzed biochemically for transforming growth factor-β1 (TGF-β1) level. Penile corporal apoptosis was determined by TUNEL method. Results: Erectile response was decreased in rats with BCNI and there was no significant improvement with dipyridamole treatment. TGF-β1 levels were increased in rats with BCNI and decreased with dipyridamole treatment. Dipyridamole led to reduced penile apoptosis in rats with BCNI and there was no significant difference when compared to sham operated rats. Conclusions: Although fifteen-day dipyridamole treatment has failed to improve erectile function in rats with BCNI, the decline in both TGF-β1 levels and apoptotic indices with treatment may be helpful in protecting penile morphology after cavernous nerve injury.

title: Influence of Hemostatic Solution on Bond Strength and Physicochemical Properties of Resin Cement

description: Abstract The aim of this study was to evaluate the degree of conversion, color stability, chemical composition, and bond strength of a light-cured resin cement contaminated with three different hemostatic solutions. Specimens were prepared for the control (uncontaminated resin cement) and experimental groups (resin cement contaminated with one of the hemostatic solutions) according to the tests. For degree of conversion, DC (n = 5) and color analyses (n = 10), specimens (3 mm in diameter and 2 mm thick) were evaluated by Fourier transform infrared spectroscopy (FTIR) and CIELAB spectrophotometry (L*, a*, b*), respectively. For elemental chemical analysis (n = 1), specimens (2 mm thick and 6 mm in diameter) were evaluated by x-ray energy-dispersive spectroscopy (EDS). The bond strengths of the groups were assessed by the microshear test (n = 20) in a leucite-reinforced glass ceramic substrate, followed by failure mode analysis by scanning electron microscopy (SEM). The mean values, except for the elemental chemical evaluation and failure mode, were evaluated by ANOVA and Tukey’s HSD test. The color stability was influenced by storage time (p&lt;0.001) and interaction between contamination and storage time (p&lt;0.001). Hemostop and Viscostat Clear contamination did not affect the DC, however Viscostat increased the DC. Bond strength of the resin cement to ceramic was negatively affected by the contaminants (p&lt;0.001). Contamination by hemostatic agents affected the bond strength, degree of conversion, and color stability of the light-cured resin cement tested.

title: PERCOLATE QUALITY IN SOIL CULTIVATED WITH APPLICATION OF WASTEWATER FROM SWINE SLAUGHTERHOUSE AND DAIRY PRODUCTS

description: ABSTRACT The objective of this study was to evaluate the quality of the percolate in soil columns cultivated with Tiffon-grass 85 under different wastewater rates from swine slaughterhouse and dairy. The experiment was conducted at the Department of Engineering at the Federal University of Lavras, in PVC columns with 0.30 m of diameter and 1.2 m deep, filled with Dark Red Latosol cultivated with Tifton-grass 85. The treatments consisted of a (AQT0) control with recommended chemical fertilization for Tifton-grass 85 (300 kg ha-1 year-1 of N), and four doses of SSW and DPW (100, 200, 300 and 400% of the recommendation) in a CRD with 3 replications. The samples of percolated were collected and characterized weekly. The treatments of highest dosage have obtained COD, after 120 days, of 47.7 mg L-1 (AAT3) and 38.6 mg L-1 (AAT4). Although nitrate concentrations were elevated on the earlier months, the greater assimilation of nutrients by the Tifton-grass 85 and the reduction of the mineralization of organic material resulted in lower nitrate concentrations of 10 mg L-1.

title: Investigation of phytochemical contents, in vitro antioxidant and antibacterial behavior and in vivo anti-inflammatory potential of Ecballium elaterium methanol fruits extract

description: Abstract Ecballium elaterium species are mostly used as therapeutic agents and food ingredient. The current work was designed to investigate phytochemical contents, antioxidant, antibacterial, and anti-inflammatory properties of methanol fruits extract of Ecballium elaterium. Good antioxidant activity was observed with IC50 values of 156 ± 4 and 377 ± 6 μg/mL for DPPH and ABTS, respectively, and EC50 of 126 ± 4 µg/mL for FRAP assays, which is related with their richness in total phenolic, flavonoid and condensed tannins contents. The results of antibacterial activity showed the effectiveness of methanol extract against Bacillus cereus with value of inhibition zone diameter of 15 ± 0 mm and a MIC and MBC values of 6 ± 0 and 12 ± 0 mg/mL, respectively. The in vivo anti-inflammatory effects have been also studied by carrageenan induced rat paw edema assay and the results revealed that a dose of 75 mg/kg induced a significant inhibition of 66.4% at 2 h. FT-IR spectral data justified the presence of biological functional groups such as ─OH, C─H, C─O, C─C and C=O. These results highlighted the potential using of Ecballium elaterium fruits extract as natural antimicrobial, antioxidant and anti-inflammatory agents for food applications and for the pharmaceutical industry.

title: Synthetic mesh repair of an anterior perineal hernia following robotic radical urethrocystectomy

description: ABSTRACT Introduction: Perineal hernia is a protrusion of intra-abdominal viscera through a defect in the pelvic floor and is a rare but challenging complication after extensive abdominoperineal surgery. There have been small series published after colorectal exenteration, but no cases have been reported after radical cystectomy and urethrectomy. Case Presentation: A 68 years old woman developed an anterior perineal hernia, with no vaginal prolapse, after an anterior exenteration for bladder cancer. A perineal approach with the use of a synthetic polypropylene mesh was chosen to resolve the condition. After 6 months of follow-up, the patient has no symptoms or recurrence of the anterior perineal hernia. Conclusion: To our knowledge, this case is the first report of perineal hernia after radical urethrocystectomy. Although being a case report, this article describes a potential and challenging complication after extensive anterior pelvic surgery, that could increase its incidence in the future. Literature review shows that whether perineal, abdominal or combined approach is chosen, surgery must respect hernia repair principles.
