title: Are exercises with or without occlusal splints more effective in the reduction of pain in patients with temporomandibular disorders of myogenic origin? A systematic review

description: Abstract Temporomandibular disorders (TMD) is a term used to describe a set of clinical conditions that may compromise the temporomandibular joint (TMJ) and masticatory muscles and/or associated structures, considered the most frequent cause of orofacial pain of non-dental origin. In recent years, many forms of physical therapy have been used in the treatment of TMD to reduce pain and improve the range of mandibular movement present in this impairment. Among these resources are kinesiotherapy (exercise), electrothermal and manual therapy, acupuncture, training posture, mobilizations, and biofeedback. Objectives To determine if exercises with or without occlusal splints are effective in reducing pain in patients with temporomandibular disorders (TMD) of myogenic origin. Methodology This systematic review was registered in the International Prospective Register of Systematic Reviews (CRD 42019134244). Controlled trials published in PubMed, Scopus, and Cochrane Library following PRISMA guidelines up to April 2022 were randomized and included. The population above 18 years, which evaluated the effectiveness of exercise with or without occlusal splints in reducing pain in patients with TMD of myogenic origin, diagnosed through the Research Diagnostic Criteria for Temporomandibular Disorders, was also included. There was no restriction on the period of publication. Cochrane risk of bias analysis was performed. Results Of the five included articles, all showed a reduction of pain, but without significant differences between the interventions performed. Additionally, studies that evaluated the quality of life and mandibular movements showed a reduction in pain, but no significant differences between therapies. Conclusion The analyzed studies showed no difference in the improvement of pain, quality of life, and mandibular movements between the groups that performed only exercises or the associated treatments.

title: SARS-COV-2 VIRAL LOAD IN GOIÂNIA WASTEWATER: WASTEWATER-BASED EPIDEMIOLOGY FOR A COVID-19 EARLY WARNING SYSTEM

description: COVID-19 is currently the most critical disease in the world. Thus, several tools have been used in the last two years to contain the spread of SARS-CoV-2. In this perspective, Wastewater-Based Epidemiology (WBE) provides valuable data by including symptomatic, pre-symptomatic, and asymptomatic individuals and anticipating clinical cases. For 37 weeks, the SARS-CoV-2 viral load was monitored in sanitary sewage samples from Goiânia-Brazil. Through pre-concentration, extraction, and purification of viral RNA, followed by RT-qPCR, it was detected in 83.78% (31/37) of the weeks the presence of fragments of the genetic material SARS-CoV-2 with viral loads ranging from 105 to 108 genome copies L-1. The viral load in the wastewater samples was related to the clinical data of the municipality, demonstrating its ability to promote an Early Warning System (EWS). In early 2022, it was possible to predict the increase in clinical cases 3 weeks in advance and issue an alert note to the health authorities. Prevalence estimates ranged from 0.003 to 0.5% and showed good agreement with observed values. Thus, monitoring effluents become another essential tool that can help combat the pandemic’s advance, especially in countries with scarce resources.

title: Dynamics of Tree Population Structure After Disturbance of Araucaria Forest Remnants

description: Abstract This study aimed at evaluating and compare the changes from 2012 to 2016 in the structure and floristic composition of a remnant Araucaria Forest. The entry and mortality rates were 2.2% year-1 and 6.9% year-1, respectively. Among the most represented species, those with the greatest yearly increases in their numbers were Sebastiania brasiliensis, Eugenia uniflora, and Allophylus sp. Average mortality density was 498 ind ha-1, and was particularly high for the following species: Casearia decandra (representing 32.3% of total mortality), Eugenia sp. (27.2%), Cinnamodendron dinisii (24.5%), and Lithraea brasiliensis (25.2%). The pioneer species represented 8.33% of income and 29.17% mortality, and secondary species composed 33.33% and 62.50% of income and mortality, respectively. Climax species accounted for 8.33% of income and did not contribute to mortality. The high tree mortality observed in the present study can be attributed, among others factors, to the effects of natural disturbance that occurred in the period.

title: In vitro and ex vivo antiplasmodial activity of 1-(3-benzyloxy-4-methoxy-phenyl)-3-(3,4,5-trimethoxy-phenyl)-propan-1-one) against circulating strains of Plasmodium spp. in the state of Rondônia, Brazil

description: Abstract Malaria is a disease caused by Plasmodium spp. protozoa. The ability of Plasmodium to develop resistance to current antimalarial drugs makes the study of chemotherapeutic alternatives extremely important. This study aimed to evaluate the antimalarial activity of compound 3286938 (1-(3-benzyloxy-4-methoxy-phenyl)-3-(3,4,5-trimethoxy-phenyl)-propan-1-one), which presents in its structure a 3,4,5-trimethoxyphenyl group, in vitro, using the W2 strain of P. falciparum and against circulating strains of P. vivax and P. falciparum from the state of Rondônia. The compound 3286938 obtained an IC50 of 24.4 µM against the W2 strain of P. falciparum, and against the circulating strains, it presented a median (MD)=38.7 µM for P. vivax and MD=6.7 µM for P. falciparum. As for toxicity, 3286938 showed CC50 &gt; 500 µM for VERO and HepG2 strains with a selectivity index greater than 12.9, a ratio calculated for P. falciparum and P. vivax regarding Vero and HepG2 cells. The compound was not considered hemolytic in in vitro assays, thus indicating the specificity of its antiplasmodial action. Based on the results presented, and considering the unprecedented character of the compound, it can be concluded that 3286938 was shown to be promising for complementary in vitro and in vivo studies aiming to produce effective antiplasmodial action.

title: ARGUMENTATION FROM THE TEACHING OF THE CHEMICAL SOLUTIONS

description: This research, whit the design and implementation of contextualized laboratory activities in chemistry was carried out, in order to demonstrate the level of argumentation presented by teachers in initial training, first semester of the Bachelor of Natural Sciences program and Environmental Education of the Pedagogical and Technological University of Colombia “UPTC”. This research was developed with a qualitative, interpretive and phenomenological research approach, allowing us to observe the progress presented by the students under study, in terms of argumentative processes, taking as reference Toulmin who describes different levels of argumentation. The research was carried out in three phases: a diagnostic phase that allowed identifying the initial state of the teachers in training, a second phase of design and implementation of the sequence of activities based on situations of context, and finally a third evaluation phase in which the levels of argumentation reached by the students, having as a fundamental basis the triangulation of data between the experiences of the students confronted with theoretical references that would allow us to account for the results found. It was possible to identify the difficulty that students present when preparing structured arguments as proposed by Toulmin, demonstrating the lack of appropriation of scientific language that students have and the low development of this competence at the different levels of academic. Is important to promote the use of different didactic strategies such as experimentation in the classroom, which allow strengthening the different argumentation processes in students.

title: Determination of sunset yellow, allura red, and fast green using a novel magnetic nanoadsorbent modified with Elaeagnus angustifolia based on magnetic solid-phase extraction by HPLC

description: Abstract Sunset yellow (SY), allura red (AR) and fast green (FG) are frequently used in commercial food products, although they are considered to be hazardous to public health due to their toxic efficacy and high exposure risk potency. In this study, a new, rapid, and reliable method based on a magnetic solid-phase extraction (MSPE) was developed for the simultaneous determination of SY, AR, and FG. Fe3O4 modified with Elaeagnus angustifolia was used for the first time as an adsorbent (Fe3O4-EA) in MSPE. It was characterized with scanning electron microscopy, Brunauer Emmet Teller surface area analysis and X-ray diffraction. MSPE parameters were optimized in terms of pH, adsorption, and elution time and elution volume. High-performance liquid chromatography was used for dye quantitation. Analytical separation was performed by applying ammonium acetate buffer, acetonitrile, and methanol as the mobile phase to a C18 reverse-phase analytical column. Intraday and inter-day repeatability of the method performed at the concentration of 0.2, 1.0 and 2.0 µg/mL exhibited &lt;8.1% RSD (n=3). The limit of detection values was between 0.05-0.1 µg/mL. The adsorption data of SY, AR and FG on Fe3O4-EA were fitted with the Langmuir model with qmax values of 45.0, 70.4 and 73.0 mg/g, respectively.

title: ACRYLAMIDE MITIGATION IN POTATO CHIPS BY ADDITION OF POLYPHENOLS FROM INCA MUÑA (Chenopodium bolivianum).

description: The aim of this study was to evaluate the influence of Inca muña phenolic antioxidants in the reduction of acrylamide (AA) in potato chips. The potatoes were cut into 2 mm thick slices, the addition of antioxidants was evaluated by immersion at atmospheric pressure and by vacuum impregnation (VI) at 80 kPa for 10 min. In both cases, two antioxidant concentrations were used (1 and 2 mg Gallic acid equivalents (GAE) mL-1) and times of 15, 30, 60 and 120 s. The greatest reduction of AA was obtained by VI with 1 mg GAE mL-1 for 120 s (67.4%) and 2 mg GAE mL-1 for 15 s (59.3%); while immersion at atmospheric pressure with 2 mg GAE mL-1 for 30 s and 60 s resulted in reductions of 50.8 and 50.9%, respectively. Besides, the addition of phenolics from Inca muña had no influence on the colour of potato chips. VI treatment resulted in increased amounts of phenolic compounds and antioxidant capacity in the potato chips being the most abundant phenolic compounds hesperidin and luteolin glucoside; while in the control samples phenolic corresponded to chlorogenic acid isomers.

title: Effect of natural food consumption on the first phase of pirarucu grow-out in ponds and cages

description: ABSTRACT Pirarucu, Arapaima gigas is a fish species of great social and economic importance in the Amazon region, where they are often farmed in earthen ponds. Intensive cage aquaculture has been growing in Brazil, which could be an alternative means to farm pirarucu, reducing costs and increasing productivity. We evaluated the contribution of natural food organisms in semi-intensive (ponds) and intensive (cages) production systems, and their effect on pirarucu growth and economic performance during the first phase of grow-out. Four ponds (300 m2) and four cages (4.0 m³) were stocked, respectively, with 120 (0.4 fish m-²) and 160 (40 fish m-³) juvenile pirarucu (28.03 ± 6.34 g, 11.75 ± 0.80 cm). The study was conducted for 105 days and fish were fed with commercial feed. Fish growth and plankton intake were evaluated every two weeks. Survival rate, standard length, weight gain and final weight were higher in fish reared in earthen ponds than in cages. Feed conversion of fish kept in ponds was lower (0.96 ± 0.06) than in cages (1.20 ± 0.11). The consumption of natural food organisms was observed, despite artificial feed being fed in both systems. The relative abundance of zooplankton and insects in stomachs was directly proportional to fish weight gain in ponds, and inversely proportional in cages. Higher economic efficiency rate and lower average production cost were calculated for earthen ponds. Our results indicate that the cost-benefit of the first phase grow-out of A. gigas is better in earthen ponds.
