title: Stratigraphic Relations of the Ipubi Formation: Siliciclastic-Evaporitic Succession of the Araripe Basin

description: ABSTRACT The Ipubi Formation represents the Aptian-Albian siliciclastic-evaporitic succession of Araripe Basin, NE Brazil. This succession comprises siliciclastic rocks (bituminous shales and claystones) and evaporites (gypsum and secondary anhydrite) and represents part of the lacustrine-shallow marine post-rift phase I. This study used sequence stratigraphy concepts to define the relations between changes in the relative lake level and the formation of Ipubi deposits. Results show that the organic-rich shales of the Ipubi Formation formed during a transgressive pulse that covered large areas of the proximal domains. These deposits overlie a regional unconformity that marks the end of the deposition of the underlying Crato Formation. A High Stand stage that followed the transgression influenced the formation of evaporitic deposits. Climate conditions played a major role in influencing the triggering and stopping of evaporite deposition. Thus, a new relative lake level fall event caused the exposure of the Ipubi Formation deposits, and created another regional subaerial unconformity accompanied by widespread karstification of evaporite beds. A posterior transgression caused the deposition of siliciclastic rocks of the Romualdo Formation over the Ipubi Formation strata, and also promoted a new event of karstification of the Ipubi upper evaporite beds.

title: Soil fertility and agriculture yield with the application of organomineral or mineral fertilizers in solid and fluid forms

description: Abstract: The objective of this work was to evaluate the effects of organomineral and mineral fertilizers, in their solid and fluid forms, on soils with variable charges with high fertility built up from nitrogen, phosphorus, and potassium contents in the soil and plant, as well as on corn (Zea mays) and black oat (Avena strigosa) yield. The treatments consisted of one control and four fertilizers - two organomineral and two mineral - in solid (SO, solid organomineral; and SM, solid mineral) and fluid (FO, fluid organomineral; and FM, fluid mineral) forms applied in Rhodic Kandiudox and Distrochrept soils with no-tillage. The use of organomineral or mineral fertilizers in fluid and solid forms increases total N content in the soil, maintains exchangeable K content in both soils, and may enhance available P content to the depth of 0.6 m in Distrochrept. These factors allowed significantly increasing corn yield, regardless of the fertilizer, and establishing greater residual effect for fluid organomineral fertilizer in the winter black oat yield, even in soils with high fertility.

title: Prognostic value of serum brain-derived neurotrophic factor levels in patients with Chagas cardiomyopathy

description: BACKGROUND Serum brain-derived neurotrophic factor (BDNF) levels have been shown to be lower in patients with Chagas cardiomyopathy (ChC) than in patients with non-dilated chagasic cardiomyopathy. However, its prognostic value was not established in patients with ChC. METHODS Forty-nine patients with ChC (50 ± 7 years, New York Heart Association “NYHA” I-III); were evaluated by echocardiography, exercise testing, and blood analysis. Serum BDNF levels were determined using enzyme-linked immunosorbent assay sandwich. Patients were followed-up, and cardiac death was considered the end-point. The survival analyses were performed using Kaplan-Meier and Cox regression. RESULTS After 39 ± 14 months of follow-up, 12 patients (25%) died. The concentration of 2.5 ng/mL was the optimal cut-off value to predict survival with significant difference between the groups with low (≤ 2.5 ng/mL) and high (&gt; 2.5 ng/mL) BDNF levels (p = 0.006). Lower serum BDNF levels (hazards ratio (HR) 1.1, 95% confidence interval (CI) 1.1-1.4; p = 0.001), peak oxygen uptake (HR 1.2, 95% CI 1.0-1.3; p = 0.009), and left ventricular ejection fraction (HR 0.8, 95% CI 0.7-0.9; p = 0.001) were the independent predictors of survival. The combination of low serum BDNF levels and reduced left ventricular ejection fraction were highly predictive of death (HR 5.6, 95% CI: 1.2-9.7; p = 0.026). CONCLUSION In patients with ChC, reduced serum BDNF levels, especially if associated with systolic function, may provide useful prognostic information.

title: Effects of Pistacia terebinthus seed meal and different storage times on egg quality of laying hens

description: ABSTRACT The present study examined the effect of supplementing the diets of laying hens with Pistacia terebinthus seed meal on egg quality during different storage intervals. A total of 192 laying hens (Babcock) were divided into six groups, and each group was further divided into four subgroups with eight hens each. Pistacia terebinthus seed meal was added to the diets of laying hens in the experimental groups at a rate of 0, 10, 20, 30, 40, and 50 g kg−1 of feed. At the end of the study (56 days), a total of 288 eggs (48 eggs from each group) were collected randomly. Seventy-two eggs were analyzed on day zero of storage, while the other eggs were stored at a temperature of 4 °C. The remaining eggs were analyzed after 10, 20, and 30 days of storage. The result revealed that, at 30 days of storage, the supplementation of terebinthus had a significant effect on the Haugh unit on inclusion levels of 20 and 40 g kg−1. Likewise, the inclusion level of 30 g kg−1 manifested a significant impact on yolk color at 20 days of storage. Eggshell breaking strength and egg weight remained unaffected. Terebinthus seed could be used to extend the storage time of eggs without any adverse effect on egg quality.

title: Comparison of five methods of extraction of Staphylococcus aureus DNA for molecular detection by PCR

description: Abstract INTRODUCTION Molecular techniques for the detection of pathogens have been shown to be effective diagnostic tools with high sensitivity and short turnaround times. METHODS This study compared five Staphylococcus aureus DNA extraction methods for detection by the polymerase chain reaction. RESULTS: The concentration and purity of the extracted DNA showed that the methods did not yield DNA of significant quality. However, most protocols yielded 100% positivity, even with low DNA concentrations. CONCLUSIONS: Although one protocol seemed more efficient than the others, PCR was sensitive enough to allow for detection of S. aureus with all the protocols.

title: FULL-THICKNESS ENDOSCOPIC GASTRIC RESECTION USING A STAPLER AND GASTROSTOMY: A FEASIBILITY STUDY

description: ABSTRACT Background: Laparoscopic sleeve gastrectomy (LSG) is currently the most frequently performed bariatric procedure in Turkey. The goal of weight reduction surgery is not only to decrease excess weight, but also to improve obesity related comorbidities and quality of life (QoL). Aim: To evaluate the impact of LSG on patient quality of life, weight loss, and comorbidities associated with morbid obesity according to the updated BAROS criteria. Methods: Eleven hundred thirty-eight adult patients were undergone to LSG by our bariatric surgery team between January 2013 and January 2016. A questionnaire (The Bariatric Analysis and Reporting Outcome System - BAROS) was published on social media. The data on postoperative complications were collected from hospital database. Results: Number of respondants was 562 (49.4%). Six of 1138 patients(0.5%) had leakage. All patients who had leakage were respondants. The overall complication rate was 7.7%. After a mean period of 7.4±5.3 months(1-30), mean excess weight loss was 71.3±27.1% (10.2-155.4). The respondants reported 772 comorbidities. Of these, 162 (30%) were improved, and 420 (54.4%) were resolved. The mean scores for QoL were significantly increased after LSG (range, p&lt;0.05 to &lt;0.001). Of the 562 patients, 26 (4.6%) were classified as failures; 86 (15.3%) fair; 196 (34.9%) good; 144 (25.6%) very good, and 110 (19.6%) excellent results according to the updated BAROS scoring system. Conclusion: LSG is a highly effective bariatric procedure in the manner of weight control, improvement in comorbidities and increasing of QoL in short- and mid-term.

title: Study of lipase production by Burkholderia cepacia

description: ABSTRACT The use of enzymes on an industrial scale has enabled the development of technological processes with an efficiency similar to those made by nature, which makes this technology one of the most promising fields in new technologies for synthesis of high-added value compounds. This paper aimed to study the production of lipase by Burkholderia cepacia using the response surface methodology. We used the following variables: concentrations of potassium, magnesium, soybean oil, corn steep liquor and pH. We observed that, among the used concentrations, potassium, corn steep liquor and soybean oil positively influenced the lipase production. Bioflo III showed the best performance among the bioreactors used for the enzyme production, possibly due to a better distribution of mass and movement transfer phenomena, reaching values of up to 2.43 U mL-1 at 120 hours of fermentation.

title: Influence of hesperidin and vitamin C on glycemic parameters, lipid profile, and DNA damage in rats treated with sucrose overload

description: ABSTRACT We evaluated the influence of hesperidin and vitamin C (VitC) on glycemic parameters, lipid profile, and DNA damage in male Wistar rats treated with sucrose overload. Rats were divided into six experimental groups: I-water control; II-sucrose control; III-hesperidin control; IV-VitC control; V-co-treatment of sucrose plus hesperidin; VI-co-treatment of sucrose plus VitC. We measured the levels of triglycerides, total cholesterol, HDL-c, LDL-c, fasting glucose, and glycated hemoglobin (A1C). DNA damage was evaluated in blood and brain cells using the comet assay and the micronucleus test was used to evaluate chromosomal damages in the rat bone marrow. Co-treatment with VitC, but not with hesperidin, normalized the serum glucose. No effect of co-treatments was observed on A1C. The co-treatment with VitC or hesperidin did not influence the lipid profile (p&gt;0.05). Rats co-treated with hesperidin had a significantly lower DNA damage level in blood (p&lt;0.05) and brain (p&lt;0.05). Rats treated with VitC only, but not those co-treated with VitC plus sucrose, had significantly higher DNA damage in brain (p&lt;0.05). No significant differences were observed in the results of micronucleus test (p&gt;0.05). Hesperidin and VitC showed different effects on sucrose and DNA damage levels. While VitC lowered the serum glucose, hesperidin reduced the DNA damage.
