  • CHARACTERIZATION OF BIOACTIVITY OF EXTRACTS OF THE PLANT SPECIES JACARANDA RUGOSA A.H. GENTRY

    The use of plants by man as a way to treat diseases is an ancient practice and widely used within the communities. Plants said to be medicinal present in their composition substances capable of altering the systematic functioning of organs, and may influence the treatment of diseases. The branch of science that studies plants and their ethnofarmacologic characteristics has attracted industries and researchers to elucidate their real biological influences in the organism. The Jacaranda rugosa, native plant of the caatinga biome, has been used in the treatment of infections and skin wounds and in the treatment of diseases. In order to evaluate the bioactivities of this species, the methodology of phytochemical prospecting was used, through thin layer chromatography, the verification of the antioxidant potential of leaf and branch extracts, through techniques such as neutralization of DPPH and ABTS radicals, in order to identify the functioning of the lity and the performance of cellular protection against oxidizing agents. In addition, microbiological techniques were used to evaluate the efficiency of extracts in acting as bactericide against disease-causing pathogens. As results, phytochemical prospection demonstrated the presence of secondary metabolites tannins, flavonoids and coumarins, the analyses of antioxidant activities by jacanda rugosa’s DPPH radical showed considerable activities from 62.5 mg/ml. The analysis of the neutralization of ABTS radicals demonstrated efficacy of 46% and 49% of ability to react against antioxidant substances. Against the microorganisms Salmonella spp.and Staphylococcus aureus, there was the activity of the extract for Salmonella spp in 5 mg/mL of the extract, but there was no activity for S. aureus..

  • ANTIOXIDANT ACTIVITY AND HEMOTOXICITY OF MEDICINAL PLANT OF THE CAATINGA DOMAIN: AMBURANA CEARENSIS (FABACEAE)

    Amburana cearensis is a medicinal species popularly known as “cherry” or “aroma amburana” that has wide distribution in South America, being characteristic of Seasonal Forests. It also occurs in Semideciduous Seasonal Forest, restricted to rocky or limestone outcrops; in Submontane Deciduous SubmontanaSeasonalForest; in Dense Ombrophilous Forest (Atlantic Forest) and even in caatinga/dry forest. Taking into account the growing interest in the search for agents that act in the face of oxidative stress, without causing toxic effects to biological systems, the present study aimed to investigate the phytochemical composition and evaluate the antioxidant and hemotoxic activities in vitro of the aqueous extract obtained from the shells of Amburana cearensis (EAAc). Hemaglutination wasevaluated for human erythrocytes collected from people with the presence of O+ blood. In the face of the tests, Amburana cearensis presented significant results for antioxidant activity without causing erythrocyte hemolysis, highlighting the importance of the species as a source of antioxidant agents, which are recognized for blocking the evolution and acting to combat symptoms triggered by diseases associated with oxidative stress.

  • Evaluation of the Antioxidant Potential of Artisanal Liqueurs Produced From Fruits of the Caatinga Biome

    Plant extraction is a common practice performed in community with the presence of native species with strong population interest. For many Brazilian regions, extractivism acts as a complement of income for the population. The present work aimed to evaluate artisanal liqueurs produced in local communities of the State of Pernambuco in order to observe the antioxidant potentials present during production stages. For this, trials were performed with dpph and abts radicals. All the liqueurs evaluated showed antioxidant potential, with expressive results through the sequestration of the DPPH radical, comprising values of 50 CI between 0.5 and 2.25.

  • Constructing Consumers’ Mental Model with ZMET for Online Foreign Language Learning Activities

    The customers’ particular perception of any product, service, or even brand is also the representation of mental models that underlie the customers’ feelings additionally to consequently account for customer behaviour. To amass such customer insight, this article uses a vital customer analysis tool—the Zaltman metaphor elicitation technique (ZMET) to urge the perceptual and ideal meaning of customers in thinking levels that are different through visual picture and metaphor imagination, along with further incorporate the mean – end chain theory to produce the incorporated mental map for a team of consumers within the context of online language learning, therefore offering better insight into customers behaviour.

  • Incidentally Detected Microscopic Gastrointestinal Stromal Tumor: Clinicopathological and Immunohistochemical Evaluation of 11 Cases

    Aim: Gastrointestinal stromal tumor (GIST) originating from interstitial Cajal cells is the most common mesenchymal tumor of the gastrointestinal tract, often located in the stomach, but can be seen anywhere in the gastrointestinal tract. In this study, microGISTs, a preclinical form of GIST; retrospective evaluation was aimed with clinical, histopathological and immunohistochemical findings. Materials and Methods: This study included 11 cases who underwent surgery in our hospital between 2005 and 2017, were diagnosed as microGIST. Results: Three of the cases included in the study were male (27%), eight were female (73%), and the mean age was 59 years. The average lesion diameter was 0,7 cm. All lesions are asymptomatic and detected during surgeries for other reasons. In eight of 11 cases, the lesion was located in the stomach (73%) and three of them in the small intestine (27%). Mitotic activity was observed in only two cases. Spindle cell morphology was detected in all of them. While five of the cases were determined as dedifferentiated (45%), four of them were differentiated by muscle (36%), two of them were differentiated by nerve (19%). There was no risk of progressive disease in any case. In all cases, tumor cells were diffuse positive with CD117 and DOG1 in the immunohistochemical study. Conclusion: MicroGISTs are clinically different and have a pathologically significant low proliferative capacity than other similar tumors. These tumors with benign behavior potential should be kept in mind in the differential diagnosis of spindle cell mesenchymal lesions in the gastrointestinal tract.
