title: X-LINKED ADRENOLEUKODYSTROPHY IN BRAZIL: A CASE SERIES

description: ABSTRACT Objective: To describe patients with different phenotypes of X-linked adrenoleukodystrophy: pre-symptomatic, cerebral demyelinating inflammatory adrenoleukodystrophy, adrenomyeloneuropathy and adrenal insufficiency only. Methods: Specific data related to epidemiology, phenotype, diagnosis and treatment of 24 patients with X-linked adrenoleukodystrophy were collected. A qualitative cross-sectional and descriptive-exploratory analysis was performed using medical records from a reference center in Neuropediatrics in Curitiba, Brazil, as well as an electronic questionnaire. Results: The majority (79%) of patients had cerebral demyelinating inflammatory adrenoleukodystrophy, presenting aphasia, hyperactivity and vision disorders as the main initial symptoms. These symptoms appeared, on average, between six and seven years of age. There was a mean delay of 11 months between the onset of symptoms/signs and the diagnosis. Patients sought diagnosis mainly with neuropediatricians, and the main requested tests were dosage of very long chain fatty acids and brain magnetic resonance. Conclusions: All phenotypes of X-linked adrenoleukodystrophy, except for myelopathy in women, were presented in the studied population, which mainly consisted of children and adolescents. Prevalent signs and symptoms registered in the literature were observed. Most of the patients with cerebral demyelinating inflammatory adrenoleukodystrophy were not diagnosed in time for hematopoietic stem cell transplantation.

title: Elevated atmospheric CO2 concentration improves water use efficiency and growth of a widespread Cerrado tree species even under soil water deficit

description: ABSTRACT Changes in atmospheric CO2 levels are accompanied by ecological interactions involving other environmental factors, such as drought, which can severely alter the water balance of plants, thereby influencing sap flow, gas exchange, and plant growth. The objective of this study was to evaluate the water use economy, leaf gas exchange, and growth of young plants of the species Lafoensia pacari subjected to high concentrations of atmospheric CO2 ([CO2]) and soil water deficit. Increased vapor pressure deficit was observed from 1200 to 1800 hours. Plants under elevated [CO2] exhibited increased leaf photosynthesis, resulting in improved growth. Specific leaf area was lower in plants under high [CO2], mainly after soil water deficit treatment. Daily irrigated plants growing under ambient [CO2] had higher stem sap flow velocity (cm h-1) and hourly sap flow (kg h-1), mainly during the hottest hours of the day, than plants under high [CO2]. Improved water use by plants growing under high [CO2] may result in increased availability of water in the soil, partially offsetting future drought events and extending the growth period.

title: INSERTION OF THE FATHER IN THE CARE OF THE HOSPITALIZED PRETERM INFANT: PERCEPTION OF THE MULTIPROFESSIONAL TEAM

description: ABSTRACT Objective: To understand the perception of the multiprofessional health care team regarding the inclusion of fathers in the care of preterm infants who are in Intensive Care Units (ICUs). Methods: This is a descriptive study with a qualitative approach, using a semi-structured interview with 12 health care professionals of a neonatal ICU, from February to July 2017. The data were analyzed according to the Discourse of the Collective Subject. Results: Seven main ideas (MI) emerged from the text analysis, which were grouped into two themes: 1) the role of the father according to the multiprofessional health care team views (MI1: parent provider, MI2: shared care, MI3: supportive father); 2) perception of the father caring for the hospitalized preterm infant (MI4: father does not change diapers; MI5: father conquering new spaces; MI6: strengthening the bonding; MI7: father providing maternal security. Conclusions: The results of this study point out to the importance of including the father figure in the humanized care of preterm infants. Professional health care team should be more aware of fathers’ importance in the care of hospitalized preterm infants.

title: MODELING OF THE KINETICS OF CRYOGENIC FREEZING OF LIMA BEAN SEEDS AS A FUNCTION OF INITIAL WATER CONTENT

description: ABSTRACT Cryopreservation is a technique used to preserve genetic material at ultra-low temperatures in cryogenic germplasm banks. In order to enable the cryopreservation of a seed, it is necessary to study its appropriate freezing temperature and its water content, because seeds reach maximum physiological quality with high water contents, and they tolerate drying when they are orthodox seeds, but they may not tolerate cryopreservation. Therefore, the objective of this study was to analyze the influence of initial water content (50 to 10% wet basis) on the kinetic behavior of the lima bean seed at the temperature of −150 °C, in addition to determining changes in its physiological quality (germination and vigor) when cryopreserved (−150 °C) for 30 days with the variation of initial water contents (50 to 10% wet basis). For this purpose, changes in lima bean size (length, width, and thickness), sphere-equivalent radius and volume, and kinetics of seed cryopreservation as a function of its water content. The Fourier model and the Cavalcanti-Mata & Duarte models I and II were used for cryopreservation modeling, in addition to proposing a new model for cryopreservation kinetics in which water content determines the kinetic behavior. The conclusion was that the water content of 10% wb should be used for the lima bean seed cryopreservation since its physiological quality was not affected by cryopreservation at −150 °C. The model that best represents the experimental data is Cavalcanti Mata & Duarte Model II.

title: Spore diversity among species of Blechnaceae in the Atlantic Forest

description: ABSTRACT The palynological diversity of Blechnaceae in the Atlantic Forest was investigated. While the monophyletic family belongs to the group of leptosporangiate ferns, a new classification proposed by recent phylogenetic study reorganizes the family and adds new genera. To expand palynological knowledge of the group, the spore morphology of 23 species and a hybrid, distributed among 10 genera, was described. Material from herbarium collections were submitted to acetolysis and mounted on slides, with subsequent statistical analysis of spore measurements. Photomicrographs of the material were taken under both light and scanning electron microscopy. Perine ornamentation varied among psilate, rugulate and scabrate; granules and gemmae were present along with thin, smooth cristae. Species of Blechnum and Austroblechnum exhibited the greatest diversity. The attributes of the spores obtained here were able to differentiate the analyzed species, although the spore morphology of some taxa was found to be very similar. Multivariate analysis assessed the relevance of quantitative data for differentiating the taxa.

title: Study and Optimization of Raman Amplifiers in Tellurite-Based Optical Fibers for Wide-Band Telecommunication Systems

description: Abstract Here we present a numerical analysis and the optimization of a multi-pump discrete Raman amplification system based on the use of a Tellurite optical fiber as the gain media. By using previously reported optimization techniques we were able to exploit the high Raman gain of Tellurite optical fibers and its multipeak spectrum to achieve amplification over an amplification band from 1520 to 1600 nm. Average gains around 10 dB with ripples in the region of 3 dB were achieved using only 3 pumps with less than 800 mW each. Optimized systems were obtained for different lengths of fiber showing that discrete Raman amplifiers based on tellurite fibers with lengths as short as 100 meters can provide high gains and low ripples in a broad wavelength band. Lower cost systems using only 2 pumps were also analyzed in this study providing 5.8 dB of gain with only 2.4 dB of ripple for an 80 nm signal bandwidth.

title: Evaluation of Immunological Parameters in Pregnant Women: Low Levels of B and NK Cells

description: Abstract Objective To describe the immunological and hematological reference intervals of low-risk pregnant women. Methods A cross-sectional retrospective database analysis of a basic and translational study analyzing the hematological evaluation blood counts and immunophenotyping of TCD3 + , TCD4 + , TCD8 + , B, and natural killer (NK) cells of the peripheral blood in 79 low-risk pregnant women and of 30 control women from the state of Pernambuco, Brazil, was performed. Results No significant differences were detected between the hematological profiles of the 2nd and 3rd trimesters. Nevertheless, the median level of B cells decreased significantly in the 2nd (174 x 103 μL; p &lt; 0.002) and 3rd trimesters (160 x 103 μL; p &lt; 0.001), compared with the control group (296 x 103 μL). Similarly, the median level of NK cells was lower in the 2nd (134 x 103 μL; p &lt; 0.0004) and 3rd trimesters (100 x 103 μL, p &lt; 0.0004), compared with the control group (183 x 103 μL). In contrast, relative TCD4+ and TCD8+ levels increased in the 2nd and 3rd trimesters compared with the controls (TCD4 + : 2nd trimester = 59%; p &lt; 0.001; 3rd trimester = 57%; p &lt; 0.01; control = 50%; and TCD8 + : 2nd trimester = 31%; p &lt; 0.001; 3rd trimester = 36%; p &lt; 0.01; control = 24%). Conclusion Low-risk pregnant women have ~ 40% less B and NK cells in the peripheral blood, compared with non-pregnant women. These parameters may improve health assistance for mothers and contribute to define reference values for normal pregnancies.

title: Seed priming improves the germination and growth rate of melon seedlings under saline stress

description: ABSTRACT: The germination and growth of melon (Cucumis melo L.) plants can be severely affected by excess salts in the soil or irrigation water; however, negative effects of salt stress can be attenuated using appropriate methods of seed priming. Thus, effects of osmopriming as inducer of salt stress tolerance in melon seeds exposed to salinity levels were investigated in this study. Seeds were soaked for 22 h at 25 °C in the dark in distilled water (hydropriming) or 0.5% KNO3 solution (osmopriming), and after drying, were distributed in plastic boxes with blotter paper containing different NaCl solutions prepared with osmotic pressure of 0.0 MPa (control), -0.3 MPa (mild stress), and -0.6 MPa (severe stress). Unprimed dry seeds were taken as control. The plastic boxes were kept into a seed germinator, at 25 °C for 14 days. A completely randomized design in a 3 × 3 factorial schemes with four replicates of 25 seeds was used. Results showed that the seed priming with water and KNO3 may be successfully applied on melon seeds to alleviate the adverse effects of saline stress in initial stages of plant growth. However, under severe salt stress conditions, hydropriming should be used because it results in higher germination and initial growth rate of the seedlings when compared to the osmopriming. Use of unprimed seeds should not be adopted in cultivation areas affected by salinity because they result in low germination rate and reduced initial plant growth.
