title: Reproductive aspects of Hyalella carstica (Amphipoda: Hyalellidae) in a natural environment in southeastern Brazil

description: Abstract The reproductive aspects of populations are important determinants of their ability to maintain themselves throughout time. In the case of amphipods from the genus Hyalella Smith, 1874, the reproductive period is easily determined by the presence of ovigerous females and pre-copula pairs in the population. This study evaluated the fecundity, pairing patterns and reproduction period of Hyalella carstica Bastos-Pereira and Bueno, 2012 in a karst environment in the West of Minas Gerais, Brazil. Monthly, from April, 2010 to April, 2011, amphipods were sampled using a hand net with 15 cm diameter and 250 µm mesh size. In the laboratory, animals were sexed and measured, and the ovigerous state of females was evaluated. Couples in pre-copula and ovigerous females were found throughout the year, with the exception of the dry months (September−November). During drought, the stream's superficial water dried out, and only a few refuges for the population remained. Although couples were found in all months with a water flow, a higher number of unpaired males and females was found after the dry season. In all months, ovigerous females were more abundant than non-ovigerous, and the relationship between head length and the number of eggs in the marsupium was positive. Most eggs were in the first developmental stage, although all other stages were found before the dry season. Considering the frequency of pre-copula pairs, as well as ovigerous females, the reproduction in this H. carstica population seems to be continuous throughout the year, without a distinct peak.

title: HYDRAULIC PERFORMANCE OF DRIPPERS APPLYING SANITARY LANDFILL LEACHATE DILUTED IN WATER

description: ABSTRACT Drip irrigation with diluted sanitary landfill leachate favors the development of grasses on the landfill surface, however, the clogging of emitters of the irrigation systems is the major obstacle for this practice. The objective of this study was to select empirical models of the Christiansen's uniformity coefficient, distribution uniformity coefficient, and statistical uniformity coefficient of drip irrigation sets applying sanitary landfill leachate diluted in water as a function of time of operation, and quality of the effluent. An experiment was conducted in a completely randomized experimental design with three replicates, using a split-split plot arrangement, with operating pressures (70, 140, 210, and 280 kPa) in the plots, types of drippers (G1, 1.65 L h-1; G2, 2.0 L h-1; and G3, 4.0 L h-1) in the subplots, and operating time of the drip irrigation sets (0, 20, 40, 60, 80, 100, 120, 140, and 160 hours) in the sub-subplots. Data regarding hydraulic performance and effluent quality were acquired every 20 hours during 160 hours of operation and subjected to simple and multiple regression analyses. The G3 dripper operating at pressures of 70 and 140 kPa were the combinations that best attenuated biofilm clogging. The linear regression and square root were the models that best represented the reduction in the uniformity of the effluent application as a function of the operating time of the drip irrigation sets. The linear correlations denoted that calcium contents and total coliform population rates were the characteristics of the sanitary landfill leachate that most affected the drip clogging process.

title: Land feasibility map for sewage sludge application: watershed of the Piracicaba, Capivari and Jundiaí Rivers - Brazil

description: Abstract Considering the technical and economic characteristics of the final disposal of sewage sludge, this paper sought to develop a land feasibility map for sewage sludge (biosolids) application in the watershed of the Piracicaba, Capivari and Jundiaí (PCJ) Rivers. The PCJ watershed is located in the States of São Paulo and Minas Gerais, and is characterized by large urban areas, important industrial and agricultural areas, and steady population growth. Six restricted classes of soils to receive biosolid applications were considered. The criteria used were susceptibility to erosion, soil type, and restrictive criteria as protected areas, water courses and urban areas. The maps generated have shown that less than 30% of the soil of the PCJ watershed is suitable to biosolids application. Considering only the classes of restriction 0, 1 and 2, it was observed that the areas have great potential for biosolids application: 4,089.3 103 t TS year-1. The sugar cane crop and reforestation areas were considered a priority to receive applications among suitable areas. Suitable reforestation areas cover less than 0.15% of the area of the PCJ watershed, but can be useful for the treatment stations of the west region. The areas covered by sugar cane have an annual sewage sludge reception capacity of 2,582.7 103 t TS.

title: Translational research into gut microbiota: new horizons on obesity treatment: updated 2014

description: Obesity is currently a pandemic of worldwide proportions affecting millions of people. Recent studies have proposed the hypothesis that mechanisms not directly related to the human genome could be involved in the genesis of obesity, due to the fact that, when a population undergoes the same nutritional stress, not all individuals present weight gain related to the diet or become hyperglycemic. The human intestine is colonized by millions of bacteria which form the intestinal flora, known as gut flora. Studies show that lean and overweight human may present a difference in the composition of their intestinal flora; these studies suggest that the intestinal flora could be involved in the development of obesity. Several mechanisms explain the correlation between intestinal flora and obesity. The intestinal flora would increase the energetic extraction of non-digestible polysaccharides. In addition, the lipopolysaccharide from intestinal flora bacteria could trigger a chronic sub-clinical inflammatory process, leading to obesity and diabetes. Another mechanism through which the intestinal flora could lead to obesity would be through the regulation of genes of the host involved in energy storage and expenditure. In the past five years data coming from different sources established causal effects between intestinal microbiota and obesity/insulin resistance, and it is clear that this area will open new avenues of therapeutic to obesity, insulin resistance and DM2.

title: Efficacy of casein derivate CPP-ACP1

description: OBJECTIVE: A literature review of systematic reviews and in situ and in vivo randomized controlled trials was conducted in order to assess the role of casein phosphopeptide - amorphous calcium phosphate in providing caries-preventive effect superior to any intervention or placebo. METHODS: Initially, Pubmed database was searched for systematic reviews. Two systematic reviews were identified, which concluded that the quantity and quality of randomized controlled trials were insufficient to recommend the clinical use of the product. After this, Pubmed database was searched for in situ and in vivo randomized controlled trials that were not included in the reviews identified. In vivo and in situ studies yielded mixed results. RESULTS: In situ studies indicated greater efficacy of casein phosphopeptide - amorphous calcium phosphate in comparison with placebo. Whereas, in vivo studies demonstrated different findings CONCLUSION: Casein phosphopeptide - amorphous calcium phosphate had a performance equivalent to or greater efficacy than placebo; fluoride was more effective than the casein complex; casein phosphopeptide - amorphous calcium phosphate associated with fluoride showed better or equivalent performance to that of placebo. In view of available evidence, it was not possible to generalize the indication of casein phosphopeptide - amorphous calcium phosphate for preventing dental caries. Further studies on the preventive effect and longer treatment applications are recommended.

title: MACHINE TRAFFIC AND SOIL PENETRATION RESISTANCE IN GUAVA TREE ORCHARDS

description: ABSTRACT The study was conducted in irrigated commercial orchards of ‘Paluma’ and ‘Pedro Sato’ guavas, which were mapped with a Garmin GPS unit (Cx60). Sixty five sampling points were marked on a 21 x 21 m sampling grid. Gravimetric humidity and soil penetration resistance (SPR) were evaluated with the help of an automated penetrometer rod with a type 3 cone at a 45º angle (maximum SPR 15,100 kPa). Data with non-normal distribution were analyzed by geostatistics and interpolation by ordinary kriging. SPR values were higher where machine traffic occurs than on the lines where the crop is planted. There was spatial variability of the SPR among the layers evaluated, with the layer between 0.10-0.20 m, on the line of the machine traffic, presenting a higher SPR (&gt;4000 kPa).

title: Photoinactivation of Candida albicans using methylene blue as photosensitizer

description: Objective: To evaluate the effect of photodynamic therapy in the inactivation of Candida albicans planktonic cells, using methylene blue, 150 mg/mL, as a photosensitizer. Methods: Aliquots of 100 (μg/mL of the fungal suspension in a 106 cells/mL concentration were seeded in microtiter plates with 96 wells, where the same volume of methylene blue was deposited, remaining for 5 min pre-irradiation. Then, the low power laser light was applied (wavelength: 660 nm, power: 100 mW and dose: 426 J/cm2) for 128s using a portable semiconductor laser. Control experiments were performed without illumination and in the absence of methylene blue, and another in the presence of methylene blue without illumination and with illumination, replacing the photosensitizer by saline. In each experimental condition, serial dilutions (10-1 to 10-3) were obtained and 25 μL aliquots were seeded in Sabouraud Dextrose Agar duplicate. After this period, the number of colony forming units per milliliter (CFU/mL) was determined and the data were submitted to variance analysis and Kruskal Wallis test (p &lt;0.05). Results: At the concentration of 150 μg/mL, and time of 5 min incubation, the reduction was significant (p˂0.05). In the absence of irradiation, methylene blue produced no reduction in CFU/mL. Conclusion: Photodynamic Therapy presented antifungal effect against Candida albicans and can be used as an adjunct to conventional treatment.

title: Performance of Dental Care Specialties Centers of a Region Health from Bahia

description: This study aimed to evaluate the performance goals compliance of Dental Care Specialities Centers (CEOs) from Jequié’s Health Region cities. The goals overall achievement was described and reflected on the services and cities characterization variables. Secondary data from the Outpatient Information System of the Unified Health System (SIA-SUS), National Registry of Health (CNES), Brazilian Institute of Geography and Statistics (IBGE) and State Department of Health of Bahia (SESAB) were used. The performance of Jequié’s Health Region CEOs was considered not satisfactory for all establishments included, which did not meet any goal set by the Ministry of Health. Sociodemographic data and oral health teams’ coverage do not seem to influence the performance, although the time habilitation and the facilities structural and human resources conditions appear to be related to a better production. The low performance can be linked to service management issues.

title: Heart Failure: Correlation between Anthropometric Parameters, Body Composition and Cell Integrity

description: Abstract Background: Knowledge about phase angle and its use as a prognostic determinant in patients with heart failure is still scarce. Objective: To evaluate the correlation between anthropometric indicators, cardiac function and cell integrity in patients with heart failure with reduced ejection fraction. Methods: This was a cross-sectional study that evaluated patients with heart failure with reduced ejection fraction by anthropometry and bioelectrical impedance analysis. Chi-square test and Student's t test were used to analyze differences, and Pearson's linear correlation was used to evaluate associations, using p &lt; 0.05 to indicate statistical significance. Results: We evaluated 41 subjects aged 30-74 years, of which 34 were men (82.9%). Mean phase angle was higher among women (7.1%), but significant differences between men and women were found only for body fat percentage. Phase angle correlated with body mass index (r = 0.44, p = 0.004) and there was a trend of correlation of the phase angle with waist-to-height ratio (r = 0.29, p = 0.06) and the left ventricular ejection fraction (r = 0.29, p = 0.07). Conclusions: Phase angle showed a good correlation with body mass index and showed a trend of correlation with the left ventricular ejection fraction, supporting the obesity paradox and the prognostic importance of this marker. Further studies on the applicability of the phase angle in the prognosis of these patients are still needed.
