title: Upper limb weight-bearing effect on the body alignment of individuals with cerebral palsy who have spastic hemiparesis: a randomized clinical trial

description: Abstract Introduction: Cerebral Palsy (CP) patients who have spastic hemiparesis usually present asymmetrical weight shift between the affected and non-affected side. Objective: To assess the effects of upper limb (UL) weight-bearing exercises on trunk symmetry, weight shift to the affected side and possible secondary effects on gait (speed and quality). Method: eleven participants with CP were randomized into two groups: Intervention Group (IG) and Control Group (CG); IG (n = 6) performed stretching exercises of the major muscle groups of UL and lower limbs (LL) and UL weight-bearing exercises in prone and seated position for 12 weeks. The CG (n = 5) did not undergo any kind of motor therapy during the study period but received the same exercises that IG after the study. The variables analyzed were: Gross Motor Function Measure (GMFM-88); Pediatric Berg Scale; Trunk Impairment Scale (TIS); Six-minute walking test (6MWT); Ten meters walking test (10MWT); Timed Up & Go (TUG); Edinburgh Visual Gait Scale (EVGS); and ground reaction force. Results: The IG showed improvement on 6MWT, TUG, TIS and Pediatric Berg Scale (p &lt; 0.01), and CG showed improvement on GMFM-88 (p &lt; 0.04) only for the intragroup analysis. Conclusion: The exercises were effective to improve static and dynamic balance, increasing gait speed and identifying a trend of improvement on body alignment and weight shift to the affected side.

title: An Analysis of the Energetics of Tropical and Extra-Tropical Regions for Warm ENSO Composite Episodes

description: Abstract This study focuses on the quantification and evaluation of the effects of ENSO (El Niño Southern Oscillation) warm phases, using a composite of five intense El Niño episodes between 1979 – 2011 on the Energetic Lorenz Cycle for four distinct regions around the globe: 80° S – 5° N (region 1), 50° S – 5° N (region 2), 30° S – 5° N (region 3), and 30° S – 30° N (region 4), using Data from NCEP reanalysis-II. Briefly, the results showed that zonal terms of potential energy and kinetic energy were intensified, except for region 1, where zonal kinetic energy weakened. Through the analysis of the period in which higher energy production is observed, a strong communication between the available zonal potential and the zonal kinetic energy reservoirs can be identified. This communication weakened the modes linked to eddies of potential energy and kinetic energy, as well as in the other two baroclinic conversions terms. Furthermore, the results indicate that for all the regions, the system itself works to regain its stable condition.

title: Modeling of Wind Resources on Mozambique Considering a Climate Change Scenario

description: Abstract This work presents the application of the dynamic downscaling technique on the Regional Atmospheric Modeling System (RAMS6.0) forced by output fields of the global circulation model HadGEM2-ES, to estimate the wind potential over the regions of Mozambique considering the climate change scenario defined by IPCC. The results showed satisfactory performance of the RAMS6.0 model in the reproduction of mean patterns of wind fields obtained in the reanalysis compared to CFSR and MERRA during the period 1985-2005. Winds fields at 10, 50 and 100 meters Considering conditions of the IPCC emission scenario (RCP8.5) for the period 2079-2099 showed higher values in relation to the wind fields for the period 1985-2005. Furthermore, there is evidence of an increase in the wind power over regions of Mozambique for the period 2079-2099, particularly during winter in the central and southern regions of the country.

title: Impact of lumbopelvic pain on postural balance during sit-to-stand activity in pregnant women: a cross-sectional study

description: Abstract Introduction: The emergence of painful pathologies during gestation, such as lumbopelvic pain (LPP), can influence in the achievement of functional activities, such as sit-to-stand, throughout the gestational period. Objective: To compare the variables of static and dynamic postural balance (sit-to-stand activity) among pregnant women with and whitout lumbopelvic pain and the outcome variables between the gestational trimesters. Method: A total of 100 pregnant women participated in this study allocated as follows: 51 in the LPP group and 49 in the group without LPP. All participants were subjected to an evaluation protocol: filling an identification form, Analogic Visual Scale (AVS) and Oswestry Disability Index (ODI). Evaluation of postural balance was subsequently performed using the Balance Master System®. Results: 64.7% of women during the third trimester of pregnancy reported LPP. No statistically significant differences were found between LBP presence or absence in postural balance variables (p&gt;0.05). However, gestational age influenced the VFEC variable (p=0.001). Conclusion: Women during the third gestational trimester presented complaints of lumbopelvic pain. However, the data acquired suggest that women with LPP do not have alterations in postural balance during sit-to-stand movement when compared to pregnant women without pain.

title: Composite-derived monomers affect cell viability and cytokine expression in human leukocytes stimulated with Porphyromonas gingivalis

description: Abstract Objectives: Dental composites release unreacted resin monomers into the oral environment, even after polymerization. Periodontal cells are, therefore, exposed to substances that potentially elicit the immune inflammatory response. The underlying molecular mechanisms associated with the interaction between resin monomers and human immune cells found in the gingival crevicular fluid are not fully understood yet. This study investigated the ability of bisphenol A-glycidyl methacrylate (BISGMA), urethane dimethacrylate (UDMA) and triethylene glycol dimethacrylate (TEGDMA) to induce apoptosis and cytokine release by human leukocytes stimulated with a periodontal pathogen. Methodology: Peripheral blood mononuclear cells (PBMC) from 16 healthy individuals were included in this study. To determine the toxicity, the PBMC were incubated for 20 hours, with monomers, for the analysis of cell viability using MTT assay. To evaluate cell death in the populations of monocytes and lymphocytes, they were exposed to sub-lethal doses of each monomer and of heat-inactivated Porphyromonas gingivalis (P. gingivalis) for 5 hours. Secretions of IL-1β, IL-6, IL-10 and TNF-α were determined by ELISA after 20 hours. Results: UDMA and TEGDMA induced apoptosis after a short-time exposure. Bacterial challenge induced significant production of IL-1β and TNF-α (p&lt;0.05). TEGDMA reduced the bacterial-induced release of IL-1β and TNF-α, whereas UDMA reduced IL-1β release (p&lt;0.05). These monomers did not affect IL-10 and IL-6 secretion. BISGMA did not significantly interfere in cytokine release. Conclusions: These results show that resin monomers are toxic to PBMC in a dose-dependent manner, and may influence the local immune inflammatory response and tissue damage mechanisms via regulation of bacterial-induced IL-1β and TNF-α secretion by PBMC.

title: Intention of green consumption in the context of the selfish or altruistic features of the product versus the user’s environmental consciousness

description: Abstract This research analyzed the relationship between the different motivations of green consumption in the context of a product with selfish and/or altruistic characteristics, given the different levels of environmental awareness and its impact on consumer behavior. For this, explanatory research, of quantitative character, was carried out using the realization of an experiment with the scenario of social values and individual consciousness for the method. The results showed that the motivation from the perspective of environmental concern, which proposes an altruistic consumption, had a greater influence on the practice of green consumption when compared to the motivation of the social perspective (fad and individual positioning), which in turn proposes selfish consumption. The data also showed that for the technological elite the social value provided by consumption, whether by its normative perspective or social status, does not influence the practice of green consumption. Finally, the research showed that the level of environmental awareness is an important antecedent of the intention to use green products, in which users with a higher level of environmental awareness have a greater intention to consume. However, it was possible to identify a large gap between the prediction of use and the current use of green products for consumers.

title: Fatigue survival and damage modes of lithium disilicate and resin nanoceramic crowns

description: Abstract Polymer-based composite materials have been proposed as an alternative for single unit restorations, due to their resilient and shock absorbing behavior, in contrast to the brittleness of ceramic materials that could result in failure by fracture. Objective: To evaluate the fatigue strength and damage modes of monolithic posterior resin nanoceramic and lithium disilicate glass ceramic crowns. Methodology: Twenty-six resin nanoceramic (RNC) and lithium disilicate glass ceramic (LD) 2 mm monolithic crowns (n=13) were cemented on composite resin replicas of a prepared tooth and subjected to cyclic load with lithium disilicate indenters for 2 million cycles. Specimens and indenters were inspected every 500,000 cycles and suspended when presenting fractures or debonding. Surviving specimens were embedded in epoxy resin, polished and subsurface damage was analyzed. Specimens presenting fractures or severe subsurface damage were considered as failures. Survival data was subjected to Fisher's exact test; damage modes were subjected to Mann-Whitney test (p&lt;0.05). Results: There were no debonding, cohesive or catastrophic failures. Considering subsurface damage, 53.8% of RNC and 46.2% of LD crowns survived the fatigue test, presenting no statistical difference. Chief damage modes were radial cracks for RNC and inner cone cracks for LD, presenting no statistical difference. Conclusions: The results suggest that if debonding issues can be resolved, resin nanoceramic figures can be an alternative to posterior crowns. Although distinct, damage modes revealed potential to cause bulk fracture in both glass ceramic and resin nanoceramic crowns.

title: Effect of hydroalcoholic extract of Myracrodruon urundeuva All. and Qualea grandiflora Mart. leaves on the viability and activity of microcosm biofilm and on enamel demineralization

description: Abstract Objectives: The aim of this study was to assess the effect of Myracrodruon urundeuva All. and Qualea grandiflora Mart. leaves hydroalcoholic extracts on viability and metabolism of a microcosm biofilm and on enamel demineralization prevention. Methodology: Microcosm biofilm was produced on bovine enamel using inoculum from pooled human saliva mixed with McBain saliva, under 0.2% sucrose exposure, for 14 days. The biofilm was daily-treated with the extracts for 1 min. At the end, it was analyzed with respect to viability by fluorescence, CFU counting and extracellular polysaccharides (phenol-sulphuric acid colorimetric assay) and lactic acid (enzymatic assay) production. The demineralization was measured by TMR. The data were compared using ANOVA or Kruskal-Wallis (p&lt;0.05). Results: M. urundeuva All. at 100, 10 and 0.1 μg/mL and Q. grandiflora Mart. at 100 and 0.1 μg/mL reduced biofilm viability similarly to positive control (chlorhexidine) and significantly more than the negative-vehicle control (35% ethanol). M. urundeuva at 1000, 100 and 0.1 μg/mL were able to reduce both lactobacilli and mutans streptococci CFU counting, while Q. grandiflora (1000 and 1.0 μg/mL) significantly reduced mutans streptococci CFU counting. On the other hand, the natural extracts were unable to significantly reduce extracellular polysaccharides and lactic acid productions neither the development of enamel carious lesions. Conclusions: The extracts showed antimicrobial properties on microcosm biofilm, however, they had no effect on biofilm metabolism and caries protection.

title: Effect of ultrasonic and Nd: Yag laser activation on irrigants on the push-out bond strength of fiber post to the root canal

description: Abstract Objective: This in vitro study aimed to compare the efficacy of irrigants using various irrigation activation methods to the push-out bond strengths of fiber post to root canal luted with self-adhesive resin cement (SARC). Methodology: Forty-eight decoronated human canines were used. The specimens were divided into four groups corresponding with the post-space irrigation process and were treated as follows: distilled water (DW) (Control) group received 15 mL of DW; sodium hypochlorite (NaOCl)+ethylenediaminetetraacetic acid (EDTA) group was treated with 5 mL of 5.25% NaOCl, 5 mL of 17% EDTA, and 5 mL of DW; passive ultrasonic irrigation (PUI) group was treated with 5 mL of 5.25% NaOCl, 5 mL of 17% EDTA, and 5 mL of DW, and each irrigant was agitated with an ultrasonic file; and laser activated irrigation (LAI) group was treated with 5 mL of 5.25% NaOCl, 5 mL of 17% EDTA, and 5 mL of DW, and each irrigant was irradiated with Nd: YAG laser. Fiber posts were luted with SARC, and a push-out test was performed. Data was analyzed using one-way analysis of variance and Tukey HSD test. Results: The bond strength values for the groups obtained were as follows: Control (10.04 MPa), NaOCl+EDTA (11.07 MPa), PUI (11.85 MPa), and LAI (11.63 MPa). No statistically significant differences were found among all experimental groups (p&gt;0.05). The coronal (12.66 MPa) and middle (11.63 MPa) root regions indicated a significantly higher bond strength compared with the apical (9.16 MPa) region (p&lt;0.05). Conclusions: Irrigant activation methods did not increase the bond strength of fiber post to canal.

title: Challenges in measuring angles between craniofacial structures

description: Abstract Objective: Three-dimensional (3D) angular measurements between craniofacial planes pose challenges to quantify maxillary and mandibular skeletal discrepancies in surgical treatment planning. This study aims to compare the reproducibility and reliability of two modules to measure angles between planes or lines in 3D virtual surface models. Methodology: Twenty oriented 3D virtual surface models de-identified and constructed from CBCT scans were randomly selected. Three observers placed landmarks and oriented planes to determine angular measurements of pitch, roll and yaw using (1) 3D pre-existing planes, (2) 3D planes created from landmarks and (3) lines created from landmarks. Inter- and intra-observer reproducibility and repeatability were examined using the Intra-Class Correlation (ICC) test. One observer repeated the measurements with an interval of 15 days. ANOVA was applied to compare the 3 methods. Results: The three methods tested provided statistically similar, reproducible and reliable angular measurements of the facial structures. A strong ICC varying from 0.92 to 1.00 was found for the intra-observer agreement. The inter-observer ICC varied from 0.84 to 1.00. Conclusion: Measurements of 3D angles between facial planes in a common coordinate system are reproducible and repeatable either using 3D pre-existing planes, created based on landmarks or angles between lines created from landmarks.
