The objective of this study was to evaluate the cytotoxic effect food dyes sunset yellow, bordeaux red, and tartrazine yellow on cellular cycle Allium cepa L. Each dye evaluated at doses 0.4 4.0 mL, exposure times 24 48 hours in root tip cells Slides were prepared analyzed during whole cell for aberrations totaling 5,000 total each dose evaluated. mitotic index calculated, statistical analysis performed using Chi-squared test (p < 0.05). results showed that three used under system-test...
Anthropogenic activities in tropical rivers favor the eutrophication process, which causes increased concentration of heavy metals. The presence and bioaccumulation metals are directly related to genotoxic damage aquatic organisms. Thus, we evaluated (Fe, Zn, Cr, Cu Al) performed toxicogenetic tests surface (S) bottom (B) water samples Poti river (Piaui/Brazil). Cytotoxicity genotoxicity were Allium cepa, micronucleus (MN) comet assay Oreochromis niloticus. chemical analysis showed...
Among the food additives used in industry, dyes are considered most toxic. For instance, tartrazine (TRZ) is a colorant commercially available with conflicting data regarding its cytotoxic, genotoxic, and mutagenic effects. Therefore, this study aimed to evaluate cytotoxic potential of TRZ using different eukaryotic cells (in vitro).This employed 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide (MTT), brine shrimp lethality, Allium cepa Saccharomyces cerevisiae tests....
Abstract BACKGROUND This study aimed to produce activated carbon (AC) from spent coffee ( Coffea arabica ) grounds by chemical activation using zinc chloride (ZnCl 2 and nitric acid remove bentazone aqueous solutions. RESULTS The fresh were characterized thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), the AC X‐ray diffraction (XRD), infrared spectroscopy (FTIR), Brunauer–Emmett– Teller (BET), point of zero charge, electron microscopy (SEM) Boehman method....
RESUMOEste trabalho realizou um levantamento sobre o uso de plantas medicinais na cidade Picos-PI, identificou as cultivadas no horto pertencente ao Laboratório Fitoterápico Picos (LAFIPI), e analisou fitoterápicos dispensados pelo Programa Farmácia Viva triênio 2008-2010. Do total dos 750 entrevistados, 37,6% foram homens 62,4 % mulheres, dentre os quais a maioria não concluiu segundo grau (69,2%) 77,2% possuíam renda mensal até dois salários mínimos. Com relação consumo medicinais, 76,3%...
Stevia urticifolia Thunb. is an underexploited herb possessing bioactive flavonoids, saponins, and terpenoids. The aim of this study was to examine the antiproliferative toxicogenetic properties ethyl acetate extract from aerial parts (EtAcSur) upon Artemia salina, erythrocytes, Allium cepa sarcoma 180 cells fibroblasts, as well in vivo studies on mice determine systemic, macroscopic, behavioral alterations bone marrow chromosomal damage. assessment using A. salina larvae mouse blood...
O objetivo deste trabalho foi avaliar o potencial ornamental de dez acessos pimenta Capsicum spp. procedentes da Coleção Germoplasma Universidade Federal do Piauí, Brasil. experimento conduzido em casa vegetação, no Departamento Fitotecnia, Centro Ciências Agrárias, município Teresina, obedecendo ao delineamento experimental inteiramente casualizado, com três repetições. Na caracterização morfoagronômica dos acessos, conforme orientação Bioversity International, utilizaram-se os seguintes...
Abstract The objective of this study was to evaluate the action Hymenaea stigonocarpa bark hydroalcoholic extract against a mutagenic compound using A. cepa meristematic root cells as test system. treatment groups were: Negative Control (NC) – distilled water; Positive (PC) paracetamol at concentration 0.008 mg/mL, Jatoba (JC) aqueous fraction jatobá-do-cerrado 0.5 or 1.0 1.5 and Simultaneous Treatment (ST) - mg/mL associated with solution mg/mL. All were analyzed 24 48 h. Five onion bulbs...
Resumo Objetivos Avaliar o perfil dos trabalhadores rurais do município de Picos, no Estado Piauí e suas práticas atitudes quanto à utilização agrotóxicos. Métodos A coleta dados (n=159) foi realizada em Picos com levantamento socioeconômicos, equipamentos proteção individual (EPIs), armazenamento destino das embalagens agrotóxicos, toxicidade risco ambiental. Resultados maioria agricultores era sexo feminino (63%), não concluiu ensino fundamental (55,6%), tinha entre 31 50 anos (55,3%),...
St. John's wort (Hypericum perforatum L.) is an herbaceous plant that native to Europe, West Asia and North Africa recognized used worldwide for the treatment of mild moderate depression. It also has been shown be therapeutic burns, bruises swelling can its wound healing, antiviral, antimicrobial, antioxidant, analgesic, hepato-protective anxiolytic properties. The aim this study was evaluate potential cytotoxic, mutagenic antimutagenic action H. Perforatum.Meristematic cells were as test...
In this study we evaluated the action of crude aqueous extracts obtained from rhytidome Hymenaea stigonocarpa (jatobá-do-cerrado) on Allium cepa meristematic root cells in three concentrations: 0.082, 0.164, 0.328g/mL, at exposure times 24 and 48 h. The slides were prepared by crushing technique, analyzed throughout cell cycle, totaling 5000 for each control group concentration. It was found that all concentrations, including lowest which is considered ideal use, times, had significant...
The present study evaluates the acute toxicity of synthetic grape, plum and orange flavourings in root meristem cells Allium cepa at doses 3.5, 7.0 14.0 mL/kg exposure times 24 48 h, bone marrow erythrocytes mice treated orally for seven days with 0.5, 1.0, 2.0, 5.0 10.0 flavouring. results plant test showed that flavourings, both times, inhibited cell division promoted formation a significant number micronuclei mitotic spindle changes. These alterations were observed least one time...
The emerging pollutant octocrylene is not efficiently removed from effluents by conventional treatment and recurrently found in rivers. This study evaluated the adsorption of using commercial carbon biochar spent coffee grounds activated with ZnCl2. two adsorbents had an efficiency approximately 100% removal throughout experimental design. kinetics equilibrium isotherms showed a good correlation data. contaminant 40 min for both adsorbents. model best fit capacity was Langmuir biochar,...
The phytotreatment technique, which has never been used to treat emerging compounds, is in this work measure the phytoextraction of octocrylene (OC) three concentrations (200, 400, and 600 μg/L OC) by Salvinia biloba Raddi. species proved be a phytoextractor accumulating OC floating leaves at 1,500,000 μg/kg treatment 200 1,050,000 OC. Chlorophyll synthesis was affected all concentrations, especially 400 μg/L, with chlorophyll a/b ratio less than 1. Enzymatic activity responded contaminant:...
Despite their great importance for the food industry, flavorings, in general, raise a number of questions regarding cytotoxicity, mutagenicity and carcinogenicity, since, literature, there are few studies found evaluating toxicity on systemic cellular level, these chemical compounds. The root meristems Allium cepa (onion) widely used assessment compounds interest. Thus, this study aimed to evaluate, A. meristematic cells, individually combination at synthetic Cheese Cheddar identical...
