title: Toxicity of clove essential oil and its ester eugenyl acetate against Artemia salina

description: Abstract The production of compounds via enzymatic esterification has great scientific and technological interest due to the several inconveniences related to acid catalysis, mainly by these systems do not fit to the concept of “green chemistry”. Besides, natural products as clove oil present compounds with excellent biological potential. Bioactives compounds are often toxic at high doses. The evaluation of lethality in a less complex animal organism can be used to a monitoring simple and rapid, helping the identification of compounds with potential insecticide activity against larvae of insect vector of diseases. In this sense, the toxicity against Artemia salina of clove essential oil and its derivative eugenyl acetate obtained by enzymatic esterification using Novozym 435 as biocatalyst was evaluated. The conversion of eugenyl acetate synthesis was 95.6%. The results about the evaluation of toxicity against the microcrustacean Artemia salina demonstrated that both oil (LC50= 0.5993 µg.mL–1) and ester (LC50= 0.1178 µg.mL–1) presented high toxic potential, being the eugenyl acetate almost 5 times more toxic than clove essential oil. The results reported here shows the potential of employing clove oil and eugenyl acetate in insecticide formulations.

title: Ocular surface evaluation in pediatric Hashimoto's thyroiditis without thyroid-associated ophthalmopathy

description: ABSTRACT Purpose: We aimed to assess ocular surface characteristics in children with Hashimoto's thyroiditis without thyroid-associated ophthalmopathy and compare the results with those of healthy children. Methods: Twenty-two children with Hashimoto's thyroiditis (Group 1) and 20 healthy children without any ocular and/or systemic disorder (Group 2) were enrolled in the study. Ocular Surface Disease Index questionnaire, tear film osmolarity measurement (TearLab Osmolarity System, San Diego, CA, USA), Schirmer and tear film breakup time tests, meibography, and conjunctival brush cytology were performed and compared the results between the groups. Results: The study group included 19 girls and 3 boys in Group 1 and 12 girls and 8 boys in Group 2 (p=0.081). Thyroid-associated ophthalmopathy was not identified in any of the patients. Mean tear film osmolarity was 310.23 ± 11.98 mOsm/l in Group 1 and 313.60 ± 15.03 mOsm/l in Group 2 (p=0.424). Mean Schirmer test score was lower in Group 1 (14.91 ± 6.27) compared with Group 2 (23.60 ± 5.63) (p=0.001). Mean tear film breakup time was lower in Group 1 (11.78 ± 4.07) compared with Group 2 (15.1 ± 1.6) (p=0.013). Moreover, mean meibomian gland area loss was 25.01% ± 10.04% in Group 1 and 16.54% ± 6.02% in Group 2 (p=0.002). Conjunctival cytologic analysis in Group 1 revealed grade 0 changes in 6 patients (27.3%), grade 1 changes in 14 patients (63.6%), and grade 2 changes in 2 patients (9.1%), whereas 18 patients (90%) had grade 0 changes and 2 patients (10%) had grade 1 changes (p=0.001) in Group 2. Conclusions: The study demonstrates several ocular surface changes in children with Hashimoto's thyroiditis. These findings may indicate a tendency for dry eye in pediatric Hashimoto's thyroiditis patients without clinical evidence of thyroid-associated ophthalmopathy.

title: Photodegradation of Fluoxetine Applying Different Photolytic Reactors: Evaluation of the Process Efficiency and Mechanism

description: Photolytic degradation of fluoxetine (FLX), a medicine commonly known as Prozac®, was evaluated by using different photochemical processes. The ultraviolet/microwave (UV/MW) process showed higher efficiency in all the aspects evaluated in this study. The energy consumption was equivalent to 1.94 × 10-4 kW h mg-1 L (UV/MW), while in the UV process the value was 1.20 × 10-2 kW h mg-1 L. The degradation kinetics were applied to the FLX, with rate constant (k) = 0.15 ± 0.01 min-1 and linear correlation coefficient (R2) = 0.980 for UV, and k = 6.15 ± 0.08 min-1 and R2 = 0.998 for UV/MW. The FLX degradation of 99.16% (UV/MW 5 min) and 98.90% (UV 120 min) were observed, evidencing higher efficiency for the first process. The monitoring of transformation products (TPs) through chromatographic analysis enabled the identification of 9 TPs, proving that for the UV/MW process, the hydroxylated structures are verified in high quantity.

title: Evaluation of corneal layers and anterior sclera in patients with primary Sjögren's syndrome

description: ABSTRACT Purpose: We aimed to compare the thickness of anterior sclera, corneal layers, and pre-ocular tear film between patients with primary Sjögren's syndrome and healthy individuals. Methods: Fifty-one patients with primary Sjögren's syndrome and 41 healthy control participants were recruited in this cross-sectional and comparative study. The thickness of the pre-ocular tear film, corneal epithelium, Bowman's layer, stroma, Descemet's membrane, and endothelium were measured on the corneal apex. Anterior scleral thickness was measured at distances of 1 mm and 3 mm from the limbus. The anterior segment module of spectral-domain optical coherence tomography was used to measure thicknesses of pre-ocular tear film, corneal layers, and anterior sclera. Results: Tear film thickness, Schirmer's test, and tear break up time values were significantly lower in the Sjögren's disease group than in the healthy controls (p&lt;0.05). The thickness measurements of corneal layers and sclera were similar between the groups. Tear film thickness was moderately correlated with the Schirmer's test results (r=0.34, p=0.001), but there was no correlation between the Schirmer's test results and tear break up time (r=0.18, p=0.09). Conclusions: Pre-ocular tear film, as measured by anterior segment optical coherence tomography, was thinner in patients with primary Sjögren's syndrome than in the healthy controls. The thicknesses of corneal layers and anterior sclera were similar between the groups.

title: Beetle diversity in fragmented thornscrub and isolated trees

description: Abstract Due to land use change mainly for induced agriculture, Tamaulipan thornscrubin northeast Mexico has been cleared and transformed into small patches of vegetation as small as isolated trees surrounded by agricultural fields. In this study, we explored how tree isolation or growing inside a fragment of remnant vegetation influence diversity of coleopterans in two plant species (Prosopis laevigata (Humb. &Bonpl.exWilld.) M.C. Johnst. (mesquite) and Ebenopsis ebano (Berl.) Barneby (Texas ebony). We found 72 coleopteran morphospecies; fifteen occurred mainly in remnant fragments and ten mainly in isolated trees. There were more insects under isolated mesquites than under those immersed in remnant fragments, while in Texas ebony the highest beetle density for isolated trees coincided with periods of bean and maize in surrounding agriculture.

title: Irlen syndrome: systematic review and level of evidence analysis

description: ABSTRACT Background: Scotopic sensitivity syndrome, later called Meares-Irlen syndrome or simply Irlen syndrome (IS) has been described as symptoms of poor reading ability due to poor color matching and distorted graphic images. Individuals with this syndrome are considered slow, ineffective readers with low comprehension and visual fatigue. It is still uncertain whether the disease pathophysiology is an independent entity or part of the dyslexia spectrum. Nevertheless, treatments with lenses and colored filters have been proposed to alleviate the effect of the luminous contrast and improve patients’ reading performance. However, no evidence of treatment effectiveness has been achieved. Objective: The aim of the present study was to obtain evidence about IS etiology, diagnosis and intervention efficacy. Methods: A systematic review was performed covering the available studies on IS, assessing the available data according to their level of evidence, focusing on diagnostic tools, proposed interventions and related outcomes. Results: The data showed high heterogeneity among studies, and lack of evidence on the existence of IS and treatment effectiveness. Conclusion: The syndrome as described, as well as its treatments, require further strong evidence.

title: Neotectonics as a structural control of the boundaries of the Pantanal Matogrossense Sub-Regions

description: Abstract: Characterized by fluvio-alluvial sedimentation processes, the heterogeneity in the Pantanal Basin allows its division in several sub-regions, which present natural characteristics of their own. It is possible to find in the literature different proposals to subdivide the Pantanal plain, which vary in total area and number of sub-regions. Each author uses specific criteria – mainly vegetation, soil and humidity – in his delimitation, but does not consider the tectonic aspects of the basin. In this sense, we intend to analyze three Pantanal delimitations from the literature and to relate them to the neotectonic context of the Pantanal plain by comparing the boundaries proposed in the delimitations to structural lineaments present in the basin. As a result, we observe that the comparison of the Pantanal boundaries with the lineaments shows a high compatibility between them, suggesting the influence of these structures in the development of the sub-regions.

title: Complications in the first 10 phacoemulsification cataract surgeries with and without prior simulator training

description: ABSTRACT Purpose: To evaluate whether training medical residents with the Eyesi® cataract surgery simulator reduces the occurrence of intraoperative complications. Methods: This was a retrospective study in which the first 10 phacoemulsification surgeries performed by two groups of second-year ophthalmology residents were evaluated, during 2014 and 2015. The first Group consisted of seven residents from 2014 who had not had previous training with the simulator. The second Group was formed of seven residents in 2015, who had completed the C-level (intermediate) training with the simulator before beginning surgery on patients. We then compared these two groups regarding the frequency of occurrence of the four main intraoperative surgical complications: posterior capsule rupture, aphakia, and nucleus fragment dislocation into the vitreous, and extracapsular conversion. Results: A total of 140 surgeries were performed, 70 by Group 1 and 70 by Group 2. The total number of complications was 19 (27.14%) in Group 1 and nine (12.86%) in Group 2, and this reduction was significant (p=0.031). Fourteen (20%) surgeries in Group 1 and seven (10%) in Group 2 had complications. The complications were 13 posterior capsule ruptures (18.57%) in Group 1 and seven (10%) in Group 2; three eyes had nucleus fragment dislocations (4.29%) in Group 1, but only one (1.43%) in Group 2; two extracapsular conversions (2.86%) occurred in Group 1 and one (1.43%) in Group 2; and there was one aphakia (1.43%) in Group 1. Conclusions: The training with the Eyesi® cataract surgery simulator significantly reduced the total number of intraoperative complications in the first 10 phacoemulsification cataract surgeries performed by ophthalmology residents.

title: EXTREME CONDITIONING TRAINING: ACUTE EFFECTS ON MOOD STATE

description: ABSTRACT Introduction: The search for strategies aimed at reducing daily stress is increasing in the current literature. As a result, several types of fitness training are constantly being investigated for their influence on mood states. However, we know little about strategies that use higher intensities. Objective: To investigate the acute effects of an extreme conditioning training (ECT) session on the mood states of individuals with or without prior experience in this type of training. Methods: Volunteers were divided into TRAINED (n = 10) and CONDITIONED (n = 10) groups, undergoing a single 9-minute ECT session. Mood states (BRUMS scale) were analyzed at baseline, immediately afterwards, and after 30 minutes. Results: Anger, confusion and tension were significantly reduced in both groups immediately afterwards and post 30 minutes. The TRAINED group showed a significant reduction in fatigue 30 minutes after the end of the session. Effect size for all variables was considered small to moderate. The TRAINED group had significantly increased vigor immediately after the end of the session compared to baseline. However, the CONDITIONED group had significantly reduced vigor 30 minutes afterwards, in comparison to baseline. The increase in vigor in the TRAINED group was considered moderate (ES = 0.68), while the decrease in vigor in the CONDITIONED group was considered major (ES = −0.88). Conclusion: An ECT session is powerful enough to induce significant, albeit small and moderate, changes in mood states in both trained and untrained individuals in this particular type of exercise.

title: Biotic potential and reproductive parameters of Spodoptera cosmioides (Walker) (Lepidoptera: Noctuidae) in the laboratory

description: Abstract In this study we evaluate the biotic potential and reproductive parameters of Spodoptera cosmioides (Walker, 1858) under controlled conditions (25 ± 1 °C, 70 ± 10% RH and 14 hour photophase). Females, on average, (14.433 days) did not live significantly longer than their male counterparts (13.100 days). The mean durations of the pre-oviposition, oviposition and post-oviposition periods were 2.767, 10.600 and 1.067 days, respectively. The mean fecundity of females was 5,073.533 eggs and the mean fertility was 5,021.027 larvae. On average, females copulated 1.167 times. Fecundity was positively correlated with the number of copulations (r = 0.583, P &lt;0.001). The number of copulations, however, was negatively correlated whit the duration of the pre-oviposition (r = -0.560, P = 0.007) and oviposition (r = -0.479, P = 0.048) periods, and overall longevity (r = -0.512, P = 0.031). The biotic potential was estimated at 6.547 x 1021 individuals/female/year. The net reproductive rate (Ro) was 2,193.722 times per generation and the mean generation time (T) was 46.407 days. The intrinsic rate of increase (rm) was 0.166, with a finite rate of increase (λ) of 1.180, per week.

title: Application of LC-DAD Metabolic Fingerprinting in Combination with PCA for Evaluation of Seasonality and Extraction Method on the Chemical Composition of Accessions from Lippia alba (Mill) N. E. Brown and Biological Activities

description: The methodology developed in this study through the acquisition of fingerprint chromatograms by liquid chromatography-diode array detector (LC-DAD), aided by principal component analysis, made it possible to assess, in a rational way, the chemical differences between six accessions of Lippia alba and to verify the influence of the method of extraction, the seasonality and the individuality of each accession on chemical composition of its extracts. Among all extracts analyzed against cancer cell lines, eight of them showed to be more promising against a human leukemia cell line (HL-60), displaying cell growth inhibition percentage ranging between 40.0 and 52.0%. In the inhibitory activity assays against acetylcholinesterase enzyme, all extracts showed weak inhibitory effect, with highlight only for six of them, which displayed inhibition ranging between 27.0 and 32.0%.
