title: Neural modeling and statistical analysis of the degradation process of leachate by the solar photo-Fenton process

description: This study sought to obtain a neural model and statistical analyzes that represented the degradation of leachate in natura by the solar photo-Fenton process, according to the reduction of chemical oxygen demand (COD). The study used leachate from the town of Cachoeira Paulista-SP, which had low biodegradability and required pre-treatment by an oxidative process. Neural networks are presented as an alternative for the modeling of nonlinear processes such as advanced oxidation processes, which involve a large number of control variables and complex reactions. The photo-catalytic process was optimized by a fractional (24-1) factorial design in duplicate and triplicate, with the center point being the input variables at three levels: pH, solar radiation and concentrations of H2O2 and Fe2+. The treatment system used an open reactor in bench scale with a constant volume (3 L) of leachate flow of 13 L min-1 and a 2-h reaction. The optimization process showed that the individual effect of each input variable should operate at its highest level, and that the variable Fe2 + was significant for the combination. The percentage reduction of COD of the best experiment was 88.7%, which is valued at a cost of R$126.67 m-3. The degradation process was modeled via feedforward backpropagation neural networks with linear correlation coefficients for the training sets, validation and test above 0.9, indicating high prediction and generalization of the proposed neural model.

title: NITROGEN FERTILIZATION IN MASSAIGRASS: PRODUCTION AND MORPHOGENESIS

description: The objective of this study was to evaluate the morphogenetic and structural characteristics, as well as the biomass of Panicum maximumcv. Massai plants under nitrogen levels. The experiment was conducted in a randomized block design with four treatments (0, 80, 160 and 240 kg N/ha) and four replications in plots of 4 m2. The nitrogen was applied according to the treatments. Massaigrass plants responded linear and positively to N fertilization with a significant increase in the rates of elongation, appearance and senescence of leaves, stem elongation, and number of live leaves per tiller and the final length of the blade. On the other hand, the nitrogen decreased the phyllochron and leaf life span of the massaigrass, indicating a direct effect of nitrogen flow in the tissues. There was positive and linear effect of N fertilization on total dry matter of leaf and stem, but there was no effect on dry matter of dead material. Nitrogen fertilization influences tillering, morphogenesis and biomass production in massaigrass plants.

title: Eruption of the first deciduous tooth in preterm infants: a 12-month follow-up

description: Abstract Objective To analyze the eruption age of the first deciduous tooth of preterm infants from the neonatal intensive care unit and to relate with natal and postnatal factors. Material and method This prospective longitudinal study was conducted with infants from neonatal intensive care units (n=215). The inclusion criterion was prematurity and exclusion was the unavailability for follow-up and newborns with congenital syndromes/malformations, with 62 participants remaining. The exam was performed by a single operator. Data were processed by SPSS and by descriptive and comparative statistics. Result When considering the chronological age, only one infant presented erupted lower incisors at 6 months. Eruption delay (60%) can be verified when compared to the standard reported in the literature. However, when analyzed by adjusted age for prematurity, this delay was less frequent (32%). Among the natal and postnatal factors, the eruption delay was not related to birth weight, gestational age, sex, breastfeeding, finger/pacifier sucking, maternal schooling and family income. The greatest frequency of eruption delay by adjusted age occurred in cases in which the infant was considered small for the gestational age (p=0.006). Conclusion The eruption of the first deciduous tooth in preterm infants presented with delay, when assessed by chronological age. However, there was no delay when the corrected age for prematurity was used. Among the natal and postnatal factors, only the weight/gestational age relationship influenced the age of eruption.

title: Factors related to Exclusive Breastfeeding in Babies born in a child-friendly hospital in a capital of Northern Brazil

description: ABSTRACT The objective of this study was to know the factors related to Exclusive Breastfeeding in Infants born in a child-friendly hospital in the city of Belém, Pará State capital, and to verify whether the scores of the Self-Efficacy Scale in Breastfeeding were among those factors. We studied 414 mother-baby binomials which babies were born in 2016. Socioeconomic and obstetrical questionnaires applied the Self-Efficacy Scale in Breastfeeding to mothers at their hospital discharge. The breastfeeding score mean was 61 points; 32.45% of the mothers were between 19 and 23 years old; 36.56% of them had a high school diploma; 43.34% received up to a minimum wage; 62.95% lived an informal union with their partners; and 17.92% were employed. The factors related to exclusive breastfeeding involved the mother age and schooling, the fact that the mother is employed, her marital status, the partner incentive to breastfeeding, and the self-efficacy scale score.

title: Melatonin prevents hyperglycemia in a model of sleep apnea

description: Objective Obstructive sleep apnea is a common disorder associated with aging and obesity. Apneas cause repeated arousals, intermittent hypoxia, and oxidative stress. Changes in glucolipidic profile occur in apnea patients, independently of obesity. Animal models of sleep apnea induce hyperglycemia. This study aims to evaluate the effect of the antioxidants melatonin and N-acetylcysteine on glucose, triglyceride, and cholesterol levels in animals exposed to intermittent hypoxia. Materials and methods Two groups of Balb/c mice were exposed to intermittent hypoxia (n = 36) or sham intermittent hypoxia (n = 36) for 35 days. The intermittent hypoxia group underwent a total of 480 cycles of 30 seconds reducing the inspired oxygen fraction from 21% to 7 ± 1% followed by 30 seconds of normoxia, during 8 hours daily. Melatonin or N-acetylcysteine were injected intraperitonially daily from day 21 on. Results At day 35, glucose levels were significantly higher in the intermittent hypoxia group than in the control group. The intermittent hypoxia groups receiving N-acetylcysteine and vehicle showed higher glucose levels than the group receiving melatonin. The lipid profile was not affected by intermittent hypoxia or antioxidant administration. Conclusions The present results suggest that melatonin prevents the well-recognized increase in glucose levels that usually follows exposure to intermittent hypoxia. Further exploration of the role of melatonin in sleep apnea is warranted. Arch Endocrinol Metab. 2015;59(1):66-70

title: Changes in hepatic markers from environmental exposure to organochlorines in Brazil

description: Objectives: To estimate the magnitude of the association between exposure to organochlorine pesticide residues and alterations of liver markers.Methods: Cross-sectional study conducted in a population exposed to organochlorines resident of Cidade dos Meninos, Duque de Caxias (RJ), Brazil (n=354). Rates were calculated from changes in hepatic markers (Alanine aminotransferase (AST), Aspartate aminotransferase (AST), alkaline phosphatase, gamma glutamyl transpeptidade (GGT) and albumin) and then, using binary logistic regression non-conditional, was estimated the association between the presence or absence of changes and exposure groups, created based on the exposure to food contaminated soil and water on site. Odds ratios unadjusted and adjusted for exposure groups and for confounding factors and their confidence interval (95%CI) were obtained.Results: After adjustment by logistic regression, the results of this study indicate no association between changes in liver enzyme abnormalities and exposure to organochlorines.Conclusion: Finding suggests that the metabolism involving the distribution and biotransformation of organochlorine compounds in the body involves no direct toxicity to the liver.

title: Acromegaly in the elderly patient

description: ABSTRACT Acromegaly is an insidious disease, usually resulting from growth hormone hypersecretion by a pituitary adenoma. It is most often diagnosed during the 3rd to 4th decade of life. However, recent studies have shown an increase in the incidence and prevalence of acromegaly in the elderly, probably due to increasing life expectancy. As in the younger population with acromegaly, there is a delay in diagnosis, aggravated by the similarities of the aging process with some of the characteristics of the disease. As can be expected elderly patients with acromegaly have a higher prevalence of comorbidities than younger ones. The diagnostic criteria are the same as for younger patients. Surgical treatment of the pituitary adenoma is the primary therapy of choice unless contraindicated. Somatostatin receptor ligands are generally effective as both primary and postoperative treatment. The prognosis correlates inversely with the patient’s age, disease duration and last GH level. Arch Endocrinol Metab. 2019;63(6):638-45

title: Determinants of morbidities and mortality in acromegaly

description: ABSTRACT Acromegaly is a systemic disease associated with increased morbidity, presenting cardiovascular, metabolic, respiratory, neoplastic, endocrine, articular and bone complications. Most of these comorbidities can be prevented or delayed with adequate disease treatment and, more recent studies with the use of modern treatments of acromegaly, have shown a change in the severity and prevalence of these complications. In addition, acromegaly is associated with increased mortality, but recent studies (especially those published in the last decade) have shown a different scenario than older studies, with mortality no longer being increased in adequately controlled patients and a change in the main cause of death from cardiovascular disease to malignancy. In this review, we discuss this changing face of acromegaly summarizing current knowledge and evidence on morbimortality of the disease. Arch Endocrinol Metab. 2019;63(6):630-7

title: Juruá Orogeny: Brazil and Andean Countries

description: Seismic data from Petrobras (Brazilian state-owned petroleum company) show wide deformation and many reverse faults throughout the Solimões and Acre basins of northern Brazil. This deformation was observed for the first time in the Juruá River in 1976 in the Solimões Basin, and it increases toward Acre and Subandean basins from Argentine and Chile to Colombia and Venezuela. Structural inversions, block uplifts, and asymmetrical folds are attributed to compression and shearing stresses along this wide area. The severe diastrophism seen in the Juruá River area is of Late Jurassic (Kimmeridgian) age. It probably coincided with the final separation between Laurasia and Gondwana continents and the initial opening of the Central Atlantic Ocean. In Peru and neighboring countries, the same Late Jurassic orogeny is also present. It occurs in the form of widespread regional uplifts, structural inversions, tilting, faults and asymmetrical folds beneath a pronounced regional parallel or angular unconformity of latest Jurassic age, marking a first-order sequence boundary above the Upper Jurassic Sarayaquillo Formation and equivalent formations, as well as above older formations. The depositional hiatus at the upper part of the Jurassic System is attributed to reorganization of stress fields that resulted in basin inversions, followed by widespread peneplanation. The uppermost Jurassic or lower Cretaceous beds, deposited above this regional unconformity, were not affected by this tectonism in Brazilian and Subandean basins. The stratigraphy of Peruvian Subandean sedimentary basins is similar to that of the Acre Basin.
