title: Bioactive compounds and the antioxidant capacities of seed oils from pomegranate (Punica granatum L.) and bitter gourd (Momordica charantia L.)

description: Abstract Pomegranate and bitter gourd are two of the few edible fruits that contain conjugated α-linolenic acids (CLnAs) in their seeds. The CLnAs have been associated with many effects that are beneficial to health, such as antioxidant and anti-inflammatory properties. Samples of cold-pressed oils from pomegranate and bitter gourd seeds were evaluated for their phytochemical compositions (fatty acids, tocopherols and phytosterols), their qualities and their stability parameters. The in vitro antioxidant capacities of these oils were evaluated by β-carotene bleaching, DPPH• scavenging, oxygen radical absorbance capacity (ORAC) and ABTS• scavenging assays. Several differences in the compositions of the fatty acids, the bioactive compounds and the antioxidant capacities were observed for the two seed oils (pomegranate and bitter gourd) when they were assessed. The highest contents for the phytochemicals (conjugated α-linolenic acids, β-sitosterols, γ-tocopherols) and the in vitro antioxidant capacities were found in the pomegranate seed oil, when using both the DPPH• and ABTS• methods. These results have indicated that seed oils with bioactivity properties can be a challenge for more research, in order to address absorption, health benefits and technological applications.

title: Results of laparoscopic cholecystectomy in the elderly.

description: ABSTRACT Objective: to evaluate the results of laparoscopic cholecystectomy in the elderly compared with younger patients. Methods: we retrospectively reviewed computerized medical records of all patients who underwent laparoscopic cholecystectomy for chronic or acute cholecystitis from January 1, 2011 to March 31, 2018 at a single teaching hospital. We stratified the patients into two groups: elderly (≥60 years of age) and younger (&lt;60 years of age). Results: of 1,645 patients subjected to laparoscopic cholecystectomy, 1,161 (70.3%) were younger and 484 (29.7%) were elderly. The rate of male was higher in the elderly (n=185; 38.2%) group than in the younger (n=355; 30.6) (p=0.003). Jaundice was more common in the elderly (p=0.004). The rate of prior abdominal operation was also higher in the elderly (p&lt;0.001). The percentage of patients with ASA score II, III, and IV was higher in the elderly group (p&lt;0.001 in score II and III and 0.294 in score IV). Operative time was longer in the elderly (71.68±31.27) than in the younger group (p=0.001). The following perioperative data were higher in the elderly: acute cholecystitis (p&lt;0.001), conversion rate (p=0.028), postoperative complications (p=0.042), and mortality (p=0.026). Conclusion: the operative time is longer and the rate of acute cholecystitis, conversion to open cholecystectomy and postoperative complications are higher in the elderly patients submitted to laparoscopic cholecystectomy when compared with younger individuals.

title: Dynamics of vegetation structure in a fragmented landscape in Minas Gerais, Brazil

description: Abstract Considering that area and edge effects are the most important factors that lead to landscape changes from the fragmentation of terrestrial communities, the present study aimed to analyze changes in the structure of vegetation classes of a fragmented landscape. The methodology employed was based on a model of patch dynamics for the years between 1979 and 2015. The analysis was performed with quantitative (area, shape and edge effect) and qualitative (low declivity of the terrain, fire resistance and tolerance to variation in light) variables of the classes of vegetation. Processes of retraction and expansion of the vegetation classes were identified, as well as the alteration of the structure of the fragments, which resulted in the intensification of the edge effect.

title: Morphobiological, morphometric and ultrastructural characterization of sylvatic Trypanosoma cruzi isolates from Rio de Janeiro state, Brazil

description: Abstract Triatoma vitticeps is a triatomine with geographic distribution restrict to Brazil, which exhibits high prevalence of Trypanosoma cruzi natural infection. Of special epidemiologic concern, this species often invades households in the states of Rio de Janeiro, Minas Gerais and Espírito Santo. The objective of this study was to evaluate morphological and ultrastructural parameters on three T. cruzi isolates obtained from wild T. vitticeps specimens. The growth and cell differentiation of the parasite was evaluated through epimastigote and trypomastigote forms obtained in the growth curves for three distinct isolates. The maximum growth showed differences at the 20th day of the curve. Our in vitro results show a heterogeneity, regarding these features for samples cultivated under the same conditions. Morphometric analyzes based on the shape of epimastigotes and trypomastigotes corroborated such differentiation. These results highlight the need of better understanding the meaning of this diversity under an eco-epidemiological perspective.

title: Genotoxicity effects on Geophagus brasiliensis fish exposed to Doce River water after the environmental disaster in the city of Mariana, MG, Brazil

description: Abstract The Doce River basin has suffered the largest environmental accident ever occurred in Brazil with the influx of tailings from Fundão and Santarém, belonging to Samarco mining company, due to the disaster in Mariana. A spill between 50 and 60 million m3 of tailings was estimated by the company. According to Samarco, the wastewater was composed mainly of clay, silt and heavy metals like iron, copper and manganese. Thereby, the objective of the present study was evaluated the genotoxic damage in juvenile of Geophagus brasiliensis (Quoy e Gaimard, 1824) exposed to Doce river water before (DRWBA – Doce River water before acident) and after (DRWAA – Doce River water after acident) the influx of tailings from the Germano and Santarém Dam disasters in Mariana, MG, Brazil. For this, 24 individuals of the species G. brasiliensis (obtained on IFES/ALEGRE fish culture) were submitted to a bioassay with three treatments and eight replicates. The treatments were: 1) Control water (water from the urban water supply system, filtered with a 0.45 µm membrane), 2) DRBA and 3) DRAA. After 96 h, these fishes were anesthetized to remove blood for evaluation of genotoxic damage (micronucleus and comet). For the bioassay, a total of 80 L of The Doce River water were collected before the influx of tailings and after the influx and then submitted to metal quantification analysis. Fish exposed to DRWBA and DRWAA treatments showed a significant increase in both the number of erythrocyte micronuclei and the DNA damage index in relation to the control fish; however, they did not present any differences between the two treatments. The results demonstrate that the DRWBA treatment was already genotoxic for the fish, mainly due to dissolved Cu concentrations in the water. The DRWAA treatment probably presented genotoxicity due to the increase in the dissolved fraction and synergistic effects of several metals found in the tailings of the Mariana accident.

title: Melanotic Neuroectodermal Tumor of Infancy: a Clinicopathological Case Report

description: Abstract Melanotic neuroectodermal tumor of infancy (MNTI) is a rare neoplasm that affects mainly children under 1 year of age. A 4-month-old boy was referred for evaluation of a lesion with 1 month of evolution. Intra-oral examination detected a firm upon palpation submucosal nodular mass, measuring 1.5 cm in diameter, affecting the anterior maxillary alveolar ridge and covered by a slightly blue mucosa with evident telangiectasia. The patient underwent an incisional biopsy and histological and immunohistochemical analyses revealed nests of AE1/AE3 positive epithelioid cells with abundant melanin pigmentation. Other cell types, resembling neuroblasts, were also present and positive for CD56, synaptophysin and enolase. The diagnosis of MNTI was established and the patient was referred for treatment. Conservative surgical resection was performed along with 3 adjacent teeth under general anesthesia. The patient is in follow-up for 1,5 year without recurrence. Conservative surgical management of MNTI may be an alternative to maxillectomy, contributing to the patient´s quality of life.

title: Effect of hot air drying on quality characteristics and physicochemical properties of bee pollen

description: Abstract The aim of this study was to investigate the effect of hot air drying on quality characteristics, physicochemical properties, morphological structure and organoleptic characteristics of bee pollen, and compute the effective moisture diffusivity and activation energy during hot air drying of bee pollen. Bee pollen samples were dried at 40, 45, 50, 55 and 60 °C. Effective moisture diffusivity (Deff) values ranged from 1.38 × 10 −10 to 4.00 × 10−10 m2/s, and the activation energy (Ea) was found to be 42.96 kJ/mol. Protein, fat, total carbohydrates and vitamin C of bee pollen were affected by the drying temperature. Dried bee pollen samples had high solubility index, and had lower L* and b* values as compared with those of the fresh bee pollen. Total color difference (Δ E) was the lowest for the bee pollen dried at 40 °C. Morphological changes on dried bee pollen surfaces increased with increasing the drying temperature. Bee pollen dried at 40 °C took the highest sensory scores and retained its quality attributes better than the bee pollen samples dried at 45, 50, 55 and 60 °C. Hot air drying at 40 °C is recommended for the drying of bee pollen.

title: Anoxia stress and effect on flesh quality and gene expression of tilapia

description: Abstract We evaluated the effect of the length of stay out of water on stress, gene expression, pH variation, blood parameters, histological analysis and water holding capacity (WHC) in fillets of the Nile tilapia (Oreochromis niloticus) cultivated in net-tanks. For this purpose, the fishes were maintained out of water under different periods of anoxia. Three and 6 min of anoxia in the pre-slaughter period increased the blood levels and mRNA expression of heat shock protein 70 the Nile tilapia and produced fillets with a less firm texture (greater sarcomere length). The evaluated periods of anoxia did not markedly affect pH and WHC. These results demonstrate that a pre-slaughter period of acute stress of up to 6 min does not considerably affect the quality of meat. The fillets of fish slaughtered in the early evening had a higher WHC and lower plasma glucose level than those slaughtered at the other time periods (morning and afternoon).

title: Environmental structure and relationships in the setting of natural water springs in a Lower Highland Seasonal Forest in Brazilian South

description: ABSTRACT: The aim of this research was to characterize an environmental structure in the setting of tree natural water springs in a Lower Highland Seasonal Forest, and to verify the relationship between community demography and soil variables as subsidies for species identification in riparian forest recovery programs in similar environments. The research was carried out in the National Forest of Chapecó, located in the west of the state of Santa Catarina in the southern region of Brazil. For this, three water springs were demarcated, where 26 plots of 200m² in each were allocated. All individuals with diameter at 1.30m of soil height ≥5.0cm were measured. Soil samples (0 to 20cm depth) were collected in the plots for chemical and physical analysis. To relate the abundance of the species to the edaphic variables, the Canonical Correspondence Analysis (CCA) was used. A total of 76 species belonging to 64 genera of 36 botanical families were reported in the study area. The families Fabaceae and Myrtaceae presented greater floristic richness. The edaphic variables that most influenced the distribution of the species were aluminum saturation and calcium, magnesium and potassium contents. Specific groups of indicator species were formed for each water spring. The species designated as generalists are the most recommended for the initial filling and recovery of degraded springs. Further rare species and with low density must be included after the initial recovery to increase diversity.

title: Evaluation of various soaking agents as a novel tool for heavy metal residues mitigation from spinach

description: Abstract Heavy metals pollution is a global threat to the environment and ecosystem due to various human and natural activities. Heavy metal intake through vegetables and diet leads to numerous ailments such as nervous disorder, kidney damage tubular growth and bone disease. The present study was conducted to mitigate the residue of heavy metals Hg, Pb, Zn and As in spinach collected from self-grown supervised field by using different washing treatments. Amount of trace metals was measured in fresh and chemically washed spinach samples with the help of Atomic Absorption Spectrophotometer (AAS). Results revealed that highest reduction of mercury, lead, zinc and arsenic residues with 10% citric acid was 23%, 28%, 54% and 22% respectively among the tested solutions. However, tap water treatment also reduced 7%, 7%, 15% and 6, respectively. Among various washing solutions citric acid proved maximum reduction potential followed by Lemon extract, sodium carbonate, reddish extract and hydrogen peroxide respectively. The percent reduction by various solutions ranged from 7 to 23%, 7 to 28%, 15 to 54% and 6 to 22% for elimination of mercury, lead, zinc and arsenic, respectively. More reduction was found in zinc followed lead, mercury and arsenic.
