title: Coping strategies among caregivers of people with Alzheimer disease: a systematic review

description: Abstract Introduction Caregivers of people with Alzheimer disease (PwAD) report significant stress, burden and depression compared to caregivers of people with other dementias, especially when neuropsychiatric symptoms are prominent. Adequate coping strategies can modify the impact of stressful situations and increase the caregivers’ quality of life. Objective To systematically review the different coping strategies used by caregivers of PwAD to manage neuropsychiatric symptoms. Method We carried out electronic searches using MEDLINE (PubMed), SciELO, Web of Knowledge Cross Search (Thomson Scientific/ISI Web Services) and PsycINFO databases to select studies on coping in PwAD caregivers published from January 2005 to July 2017. The search terms were coping, caregivers, strategy, onset, adaptation, family, behavior, dementia and Alzheimer. The studies were organized in three categories: problem-focused, emotion-focused and dysfunctional coping strategies. Results We found 2,277 articles. After application of exclusion criteria and exclusion of redundant references, 24 articles were analyzed. Emotion-focused coping was the most commonly used strategy among PwAD caregivers. The use of this strategy associated with religion and spirituality may help reduce symptoms of depression and anxiety. Problem-focused coping strategies were mostly used with active coping interventions. Problem-solving coping may have buffered the impact of acute psychological stressors on procoagulant activity. Dysfunctional coping strategies were associated with increase of caregiver burden. Conclusion The evaluated studies showed that the use and development of coping strategies may have ameliorated the depressive symptoms, anxiety and burden of caregivers. However, longitudinal studies are still needed that clearly describe the type of coping strategy used in relation to the presented results.

title: First record of Ornithodoros faccinii (Acari: Argasidae) on toads of genus Rhinella (Anura: Bufonidae) in Brazil

description: Abstract Although a group of soft ticks (Argasidae) associated with amphibians was recently discovered in Brazilian rainforests, parasitism by these ticks on cold-blooded animals remains less common than on mammal and bird species. In this study, we identified ticks that were collected from toads that had been caught in December 2016 and January 2017, at Itinguçú waterfall (22°54’05” S; 43°53’30” W) in the municipality of Itaguaí, state of Rio de Janeiro. Tick specimens were identified using a morphological and molecular approach. In total, twelve larvae of Ornithodoros ticks were collected from three individuals of Rhinella ornata and were identified as Ornithodoros faccinii. Our results include a longer 16S rRNA mitochondrial sequence for O. faccinii that supports its phylogenetic relatedness to Ornithodoros saraivai, and we report this tick species parasitizing Rhinella toads for the first time in Brazil.

title: Central Opioidergic System Interplay with Histamine on Food Intake in Neonatal Chicks: Role of µ-Opioid and H1/H3 Receptors

description: ABSTRACT The present study was designed to examine the role of Opioidergic and Histaminergic systems on feeding behavior in 3-hour food deprived neonatal meat- type chicks. In experiment 1, chicks received intracerebroventricular (ICV) injection of (A) control solution, (B) α-FMH (alpha fluoromethyl histidine; 250 nmol), (C) DAMGO (µ-opioid receptor agonist, 125 pmol) and (D) α-FMH + DAMGO. Experiments 2-4 were similar to experiment 1, except chicken ICV injected with Chlorpheniramine (histamine H1 receptors antagonist; 300 nmol), famotidine (histamine H2 receptors antagonist; 82 nmol) and Thioperamide (histamine H3 receptors antagonist; 300 nmol) instead of the α-FMH. In experiments 5-8, birds ICV injected with the same procedure as experiments 1-4, except they were injected with DPDPE (δ-opioid receptor agonist, 40 nmol) instead of DAMGO. Experiments 9-12 were similar to the experiments 1-4, except neonatal broilers ICV were injected with U-50488H (κ-opioid receptor agonist, 30 nmol) instead of DAMGO. Then the cumulative food intake was measured until 120 min post injection. According to the results, ICV injection of DAMGO, significantly decreased food intake (p&lt;0.05) while DPDPE and U-50488H increased feeding behavior compared to the control group (p&lt;0.05). Co-administration of the α-FMH and DAMGO significantly inhibited hypophagic effect of the DAMGO in neonatal broilers (p&lt;0.05). Also, Chlorpheniramine significantly inhibited DAMGO- induced feeding behavior in neonatal chicks (p&lt;0.05). In addition, co-administration of the Thioperamide + DAMGO significantly amplified the hypophagic effect of the DAMGO in neonatal chicks (p&lt;0.05). However, famotidine had no effect on food intake induced by DAMGO (p&gt;0.05). Also, the hyperphagic effect of DPDPE and U-50488 had no affect by α-FMH, Chlorpheniramine, famotidine and Thioperamide (p&gt;0.05). These results suggested that an interconnection between central opioidergic and histaminergic systems on feeding behavior is mediated via µ-opioid and H1/H3 receptors in neonatal broilers.

title: EXTRACTION OF RICE BRAN OIL USING SUPERCRITICAL CO2 COMBINED WITH ULTRASOUND

description: Abstract Rice bran oil (RBO) contains oryzanol and tocopherols. Its recovery was performed using conventional techniques with toxic solvents that leave residues in the final product. Supercritical fluid extraction (SFE) has been used, obtaining high global yields without residual solvent. This work proposes to use ultrasound to enhance the kinetics of the RBO extraction using supercritical CO2. The factors considered were ultrasound power (160 to 320 W) and sonication time (40 to 120 min), at 40 ºC and 25 MPa. The best condition (160 W / 40 min) resulted in a 12.65 wt% extraction yield. When ultrasound was not used, the global yield dropped to 9.94 wt%, representing an increase of 27% of global yield due to ultrasound application. This increase can be assigned to the vibration effect promoted by the ultrasonic waves at the interfaces between the solid matrix and solvent. The extracts showed antioxidant activity towards the DPPH radical achieving values around 70% of inhibition. Precursors of oryzanol (campesterol, β-sitosterol, stigmasterol and 4-methylenecycloartanol) were identified in the SC-CO2 + US extracts. The results presented herein showed that SC-CO2 + US is a promising technology to be employed for the extraction of bioactive compounds.

title: Electric power load in Brazil: view on the long-term forecasting models

description: Abstract Paper aims This paper aims to discuss how the energy load forecasts used by the System Operator and the main agents of the sector are made, and for what purposes, besides discuss the forecast deviations of the ONS’s and EPE’s models and their consequences and costs to the agents involved. Originality Fill a gap in the Brazilian literature when dealing with the Electric Power Load formally, and the consequences of forecast deviation used by the operator of system. Research method Simulations are carried out to estimate the cost of deviation, in order to assess the impact of the load forecast on the system. Main findings As a result, there is an urgent need to clarify forecasting methods and strategies; to avoid, by the sector agents, justifications that optimistic forecasts are necessary as security measures. Implications for theory and practice There are evidence that small improvements in forecasting models imply significant cost reductions.

title: Checklist of Odonata (Insecta) in the state of Rio Grande do Sul, Brazil with seven new records

description: Abstract: The regional knowledge of species diversity and distribution is important to support conservation strategies for species and their habitats. The main goal of this work is to present a checklist of Odonata species in the state of Rio Grande do Sul, as well as their known locations in the municipalities. The preparation of the list was based in data gathered from collections of Museu de Ciências da Universidade do Vale do Taquari (UNIVATES), Laboratório de Ecologia e Evolução da Universidade do Vale do Taquari (UNIVATES), Museu de Ciências Naturais da Fundação Zoootânica, Museu de Zoologia da Universidade do Vale do Rio dos Sinos (UNISINOS) plus data extracted from 65 publications and the sites SpeciesLink, All Odonata and Puget Sound University. A total of 182 Odonata species were recorded, spanning nine families and 57 genera. The most representative family was Libellulidae (80 species) followed by Coenagrionidae (41 species) and seven species are new records for Rio Grande do Sul. The list of species presented here is a significant advance compared to previous counts for Rio Grande do Sul, however, our list is by no means a final one. Some regions of the state remain poorly explored, such as the border to Uruguay also in the northernmost part of the state. Several families remain poorly sampled, especially those that inhabit small forested streams and probably there are many specimens which are not cataloged and identified yet in scientific collections, both in the state and in the country.

title: Injuries caused by fish in a community of Pantanal fishermen: detection, treatment, and prevention of envenomations and trauma

description: Abstract INTRODUCTION Injuries caused by fish are common in the Pantanal, a flooded area in Midwestern Brazil. METHODS A survey was conducted to identify venomous and trauma-inducing fish and the incidence of such injuries in a local fishing community. RESULTS The injuries were caused by catfish, freshwater stingrays, and piranhas. All fishermen had suffered injuries, and nearly 30% had recent injuries. CONCLUSIONS A leaflet and discussions decreased the injuries (only two were recorded in the next year). The campaign educated fishermen about prevention of and first aid for injuries. Similar campaigns will be performed in other communities of the Pantanal.

title: New data on the Late Cretaceous lizard Dicothodon bajaensis (Squamata, Borioteiioidea) from Baja California, Mexico reveals an unusual tooth replacement pattern in squamates

description: Abstract Borioteiioids comprise an extinct family of squamates that inhabited the Northern Hemisphere during the Cretaceous and were characterized by varying patterns of tooth replacement and dental morphology. Understanding the evolution of these tooth replacement patterns has, however, been largely hampered by an extremely fragmentary fossil record. Here we present new information on Dicothodon bajaensisfrom the Campanian of Baja California (Mexico), so far known only from isolated teeth and jaw fragments. Among abundant new materials there are ten maxillae and five dentaries belonging to distinct ontogenetic stages. Whereas juveniles display active tooth replacement, older specimens show no evidence of replacement. Dicothodon bajaensis is therefore inferred to have had arrested tooth replacement later in ontogeny. This provides the first evidence of cessation of tooth replacement during late ontogeny in lizards (living or extinct). This replacement type is also an evolutionary intermediate between the typical lizard replacement pattern, observed in some borioteiioids (e.g., Bicuspidon) and the complete absence of tooth replacement since early ontogeny as observed in other borioteiioids (e.g., Polyglyphanodon).

title: Light environment influences the flood tolerance in Cordia americana (L.) Gottschling & J.S.Mill.

description: Abstract The subtropical riverine forests present a variation in soil water availability throughout the year, following precipitation seasonality. The objective of this work was to evaluate the responses of Cordia americana to different light intensities combined with soil flooding. Seedlings were acclimated to light treatments, with full sun and shade conditions. Sun and shade plants were subjected to soil flooding during periods of 10 (short) and 30 (longer) days. After 10 days, flooded plants had a higher root dry mass accumulation and soluble sugars content, regardless of the light condition. Shade plants presented higher shoot soluble sugars content in relation to the sun plants. After 30 days, a higher shoot soluble sugar content was observed in sun and shade flooded plants. In addition, a higher root soluble sugar content was also observed in sun plants under flood. Periods of short flooding, characterized in subtropical forests as from 5 to 15 days, favor the growth of shade plants and the roots sugar accumulation, fact that can explain the species distribution. However, long periods of flooding may be associated with light environment plasticity, suggesting that the sun plants present a higher flooding tolerance, directly associated with the ability to maintain the sugar content.

title: Sudden bilateral sensorineural hearing loss in a patient immunocompromised by the human immunodeficiency virus

description: Abstract It is known that in less than a third of patients presenting sudden hearing loss, the disorder can be attributed to viral infection, trauma, neoplasms, and vascular and autoimmune diseases. However, the role of the HIV in the onset of this disease has not yet been well described. A 46-year-old female, in an immunosuppression state induced by HIV infection, presented with sudden bilateral hearing loss, with no improvement despite treatment. Several mechanisms were reported by which the virus could induce damage to the auditory pathway. However, little is known regarding the prevention and treatment of this morbidity.
