title: Classification of West Indian gherkin seeds vigor by respiratory activity

description: ABSTRACT Seed companies increasingly need to obtain rapid and reliable results on seed quality. In this context, this study aimed at verifying the efficiency of CO2 measurement for classifying West Indian gherkin (Cucumis anguria L.) seed vigor, using three seed lots of cv. “Do Norte” and three of cv. “Nordestino”. In order to assess seed physiological quality, the following tests were performed: germination, seedling emergence, emergence speed index, shoot length, total dry matter, electrical conductivity and respiratory activity. The experimental design was completely randomized, with four replicates, and the means were compared by Tukey test at 5% probability level. Pearson’s simple correlation was performed between the traditional vigor tests and the respiratory activity. The results of the germination and vigor tests allowed the West Indian gherkin seed lots to be classified into different levels of physiological quality. CO2 measurement is a promising method to identify vigor differences among West Indian gherkin seed lots.

title: POSTEROLATERAL ARTHRODESIS AND INTERBODY ARTHRODESIS FOR LUMBAR CANAL STENOSIS

description: ABSTRACT Objectives: To compare the clinical outcomes and quality of life of patients surgically treated for lumbar spinal stenosis with decompression and posterolateral fusion, and decompression with interbody fusion. Methods: The study included 88 patients with lumbar canal stenosis who underwent surgery treatment (decompression and interbody fusion in 36 patients and decompression and posterolateral fusion [PL] in 52 patients). The clinical outcomes were assessed using the Oswestry Disability Index (ODI), Roland-Morris (RM) functional disability scale, and visual analog scale (VAS) for pain. These questionnaires were administered preoperatively and 1 month, 6 months, 1 year, and 2 years postoperatively. Results: Eighty-eight patients had surgery 2 years prior. The ODI and RM scale scores showed significant differences in the posterolateral group. In the interbody group, the ODI score showed a significant change only from before to 1 and 2 years after surgery. The VAS score significantly changed only from before to after surgery in the posterolateral group, but in the interbody group, the change was also observed at 1 month and 1 year after surgery. Conclusions: The two techniques are effective surgical treatment options for lumbar canal stenosis as long as they are well indicated. Level of evidence III, Comparative prospective case-control study.

title: MODELING AND OPTIMIZATION OF REMOVAL OF CEFALEXIN FROM AQUATIC SOLUTIONS BY ENZYMATIC OXIDATION USING EXPERIMENTAL DESIGN

description: Abstract Antibiotics are used globally and, after use, they enter water sources in different ways. The presence of these compounds in the environment has created concerns about the toxicity of aquatic organisms and the emergence of antibiotic-resistant bacteria. The purpose of this study was to remove cefalexin from aqueous solutions by enzymatic oxidation using response surface methodology (RSM). For this purpose, batch experiments were performed to evaluate the effect of independent variables, including temperature, pH, contact time, enzyme activity, HBT mediator concentration, and antibiotic concentration. The residual cefalexin concentration was determined by HPLC. The Box-Behnken design of experiments and RSM were used to evaluate the overlap between variables. The results showed that the oxidation efficiency increased with increasing contact time and enzyme activity and decreasing antibiotic concentration. The highest and lowest removal percentages were 90.5% and 5.54%, respectively. Considering the value of R2 (0.946) and adjusted R2 (0.95) in the RSM model, one can state that the selected model is suitable for data analysis. Finally, the second-order polynomial analysis and the quadratic model were used as the best model for finding the relationship between the main variables and cefalexin removal efficiency. The Box-Behnken Design model can be effective for optimizing enzymatic oxidation of cefalexin, and laccase can be used to remove cefalexin.

title: Comparison between Cold and Hot Test procedures in a company manufacturer of diesel engines

description: Abstract The Cold Test is an innovative process in Brazil regarding the tests in diesel engines. This process was implemented in a diesel engine company with the intention of becoming the main validation test before engines are sent to customers. Based on this hypothesis, the main reason of this investigation is to test whether it is possible to replace the Hot Test with the Cold Test. This was a shocking question, since the Hot Test is a reliable and established process for over 18 years. This research used a case study method. The detailed research has identified several criteria for comparing the two processes, such as: flowcharts, effectiveness, efficiency, complexity, approval levels, on-board worksheets and company FMEA documents. The results showed that the Cold Test process is more advantageous and sustainable, however the two processes are complementary. The study proved that the fully replacement of the Hot Test by the Cold Test is not possible, mainly the Cold Test process fails in detecting leaks.

title: Genome sequence of the H2-producing Clostridium beijerinckii strain Br21 isolated from a sugarcane vinasse treatment plant

description: Abstract We report on the nearly complete genome sequence of Clostridium beijerinckii strain Br21, formerly isolated from a sugarcarne vinasse wastewater treatment plant. The resulting genome is ca. 5.9 Mbp in length and resembles the size of previously published C. beijerinckii genomes. We annotated the genome sequence and predicted a total of 5323 genes. Strain Br21 has a genetic toolkit that allows it to exploit diverse sugars that are often found after lignocellulosic biomass pretreatment to yield products of commercial interest. Besides the whole set of genes encoding for enzymes underlying hydrogen production, the genome of the new strain includes genes that enable carbon sources conversion into butanol, ethanol, acetic acid, butyric acid, and the chemical block 1,3-propanediol, which is used to obtain polymers. Moreover, the genome of strain Br21 has a higher number of ORFs with predicted beta-glucosidase activity as compared to other C. beijerinckii strains described in the KEGG database. These characteristics make C. beijerinckii strain Br21 a remarkable candidate for direct use in biotechnological processes and attest that it is a potential biocatalyst supplier.

title: Which Method to Use for Surgical Ablation of Atrial Fibrillation Performed Concomitantly with Mitral Valve Surgery: Radiofrequency Ablation versus Cryoablation

description: Abstract Objective: The effects of energy source on the maintenance of sinus rhythm and the contribution of demographic characteristics to the case selection in patients submitted to ablation performed concurrently with mitral valve surgery were analyzed. Methods: Cryothermal (n=42; 43.8%) and radiofrequency (n=54; 56.3%) energy were employed in 96 patients submitted to mitral valve replacement and Cox maze IV procedure. Patients were called for control visits between 15 days and 12 months after discharge. The causal relationship between recurrence of atrial fibrillation and factors such as left atrial diameter, C-reactive protein, hypertension, left ventricular ejection fraction, chronic obstructive pulmonary disease, and body mass index was determined. Results: Maintenance rates of the sinus rhythm with radiofrequency and cryoablation were 97.6% and 96.3%, respectively, in the first postoperative month, whereas at the 12th postoperative month were 88.1% and 83.3%. No significant difference was found between groups in relation to the energy source. Sensitivity and specificity for left atrial diameter with a cut-off value of 50.5 mm were 85.7% and 70.7%, respectively. Sensitivity and specificity for C-reactive protein with a cut-off value of 12 mg/dL on the 15th postoperative day were 83.3% and 88.9%, respectively. The effect of body mass index on atrial fibrillation recurrence was 3.2 times. Sensitivity and specificity for left ventricular ejection fraction 37% cut-off value were 96.3% and 11.4%, respectively. Atrial fibrillation in hypertensive cases was 5.3 times more. In patients with chronic obstructive pulmonary disease, recurrence of atrial fibrillation was 40%. The causal relation between recurrence of atrial fibrillation and the studied factors was established. Conclusion: Demographic characteristics have a significant impact on ablation efficiency, while the type of energy source does not.

title: Reaction of guava cultivars to Pratylenchus brachyurus.

description: ABSTRACT The root lesion nematode (Pratylenchus brachyurus) has been found in guava plants; however, there is no information in the literature about whether the crop is a potential host or is damaged due to parasitism by this nematode. The aim of this study was to evaluate, under greenhouse conditions, the development of the guava tree cultivars Paluma, Pedro Sato, Século XXI and Tailandesa inoculated with P. brachyurus. Furthermore, inoculated plants were compared with non-inoculated ones. Evaluations of height, stem diameter, fresh mass of aerial parts, fresh mass of roots, nematode population in the roots, as well as visual aspect, were performed at six and twelve months after inoculation. According to the obtained results, cultivars Pedro Sato, Século XXI and Tailandesa are not good hosts to P. brachyurus; however, Paluma is a good host. Tailandesa presented the best development of stem diameter, fresh weight of aerial parts and fresh weight of roots, relative to the other cultivars. Paluma is susceptible and intolerant to P. brachyurus; Século XXI is resistant and intolerant to P. brachyurus; Pedro Sato is resistant and intolerant to P. brachyurus, and cultivar Tailandesa is resistant and tolerant to P. brachyurus.

title: Biodiesel Synthesis: Influence of Alkaline Catalysts in Methanol-Oil Dispersion

description: Biodiesel synthesis from soybean oil using methanol and alkaline catalysts occurs in the following two consecutive steps: dispersion of methanol in the oil and methanolysis. The effect of the alkaline catalysts NaOCH3, KOCH3, NaOH, and KOH in the dispersion step at 30-60 ºC and under mechanical stirring at 400 rpm was evaluated. The dispersion step accounts for 44.6-73.3% of the total synthesis time and was poorly favored compared to methanolysis due to the increase in temperature. The catalysts decreased the dispersion time, although most of them increased the methanol-oil interfacial tension. K-containing catalysts were more active than their Na analogues due to higher adsorption of K+ in the methanol-oil interface and the higher production of methyl esters (which act as emulsifying agents), which promote a more favorable interfacial tension. The alkaline cation effect was more significant in the dispersion step than in the methanolysis step.
