General Medicine - Abstract
Introdução: O câncer é considerado uma doença genética multifatorial, caracterizada por um início e desenvolvimento complexo e lento, passando assim por determinadas etapas, como iniciação, promoção e progressão. Dentre os diferentes tipos de câncer existentes destaca-se o câncer de mama, que tem sua origem causada por uma mutação descontrolada do DNA, do tipo somática ou germinativa. Estudos mostram que a idade é um dos principais fatores de risco associados ao câncer de mama, e se relaciona ao acúmulo de exposições ao longo da vida e às próprias alterações biológicas com o envelhecimento. Objetivos: Este estudo tem como objetivo realizar uma revisão da literatura sobre a fisiopatologia e fatores de risco associados ao câncer de mama. Metodologia: Foi realizada uma triagem nas plataformas de dados Cientific Eletronic Library Online (SCIELO), PUBMED, ScienceDirect e Virtual health library, com o uso dos descritores: câncer de mama, prevenção e tratamento. Os artigos tiveram seus resumos lidos e aqueles que se enquadravam nos critérios de inclusão foram selecionados para a pesquisa. Foram adotados como critérios de inclusão trabalhos originais publicados entre 2016 a 2022 com o intuito de analisar a fisiopatologia do câncer de mama e adquirir conhecimento sobre os fatores de risco e meios de tratamento para esta patologia. Revisão de literatura: Foram selecionados 6 trabalhos que se adequaram ao critério de inclusão. Os resultados mostram que os principais fatores de risco associados ao desenvolvimento do câncer de mama são: a idade avançada, características reprodutivas, história familiar e pessoal, os hábitos de vida, e as influências ambientais. Observou-se que o câncer de mama apresenta um desenvolvimento mais acelerado com o decorrer da idade. Além disso, foi visto que esta patologia está associada a características reprodutivas como a menarca precoce, menopausa tardia e gestação após os 30 anos. Sobre os hábitos de vida, estudos mostraram que fatores mutáveis como a obesidade, tabaco, álcool, e exposição à radiação ionizante estão relacionados ao desenvolvimento do câncer de mama. O tratamento para este câncer, no caso de tumor maligno, deve ser cirúrgico, pois haverá a necessidade de retirada do tumor. Os principais tipos de cirurgia são: mastectomia radical e parcial, e lumpectomia. Outros meios de tratamento que também são utilizados são: quimioterapia, radioterapia, hormonioterapia e o uso de drogas nos estágios iniciais. Conclusão: Observa-se que o câncer de mama ainda não pode ser prevenido totalmente, porém, existem recomendações que ajudam a reduzir o risco do surgimento desta doença. É aconselhável manter uma vida saudável, assim como evitar ingestão de bebida alcoólica, tabagismo, sobrepeso e inatividade física, visto que esses fatores contribuem para avanço da doença. Existem estratégias de rastreamento, como a mamografia e o autoexame, que ajudam na detecção da doença, aumentando a taxa de cura e sobrevida, enfatizando assim a importância da divulgação das informações.

Os Sistemas de Informações Geográficas (SIGs) são produtos dos avanços tecnológicos que a sociedade produz ao longo da história humana, principalmente a partir de meados do século XX, resultados principalmente da criação dos computadores e de sua constante modernização. O objetivo desse artigo é, portanto, incentivar o uso desses sistemas informacionais como recurso pedagógico no processo de ensino e aprendizagem da Geografia sobretudo na Educação Profissional e Tecnológica (EPT). A utilização de ferramentas computacionais têm sido progressivamente importantes na solução dos problemas socioespaciais que afligem a sociedade, colaborando com o planejamento urbano e com a gestão ambiental dos recursos naturais. A Geografia é uma das ciências que melhor se apropriam desse conhecimento, principalmente no ensino dos conteúdos geográficos. Defende-se também nesse estudo o emprego dessas ferramentas tecnológicas na resolução dos problemas oriundos de planejamentos equivocados por parte dos gestores públicos. Além disso, também podem ser usadas para sugestões de melhoria do espaço geográfico. O artigo tem caráter bibliográfico trabalhando com autores que tratem da caracterização dos SIGs sob vários aspectos, como a conceituação, estrutura e utilização. Os SIGs são um conjunto de programas que podem, se usados e metodologicamente bem estruturados, contribuir com a melhoria da qualidade de ensino da Geografia principalmente na EPT.

Glioblastoma multiforme (GM) is the most prevalent tumor among gliomas and presents the highest mortality rate among brain tumors. Berberine (BBR) is an alkaloid isoquinoline found in medicinal plants such as Coptis chinensis. Studies have been showed that BBR presents protective activity in mesenchymal cells and neurons, and antitumor properties in breast cancer and hepatocarcinoma. The aim of this study was to investigate the antitumor effects of BBR in GM U87MG cells, as well as to identify, whether such effects are mediated by oxidative stress and canonical apoptotic pathways. After treatment with several concentrations of BBR (10, 25, 100 and 250 µM) for 24, 48 and 72 h of exposure, BBR reduce cell viability of U87MG cells in a concentration- and time-dependent manner. Afterwards, it was observed that BBR, starting at a concentration of 25 µM of 24 h exposure, significantly suppressed proliferation and increased early apoptosis (53.5% ± 11.15 of annexin V+ propidium iodide− cells) compared to untreated cells (7.5% ± 4.6). BBR-induced apoptosis was independent from AMPK activity and did not change total caspase-3 and p-p53 levels. Moreover, BBR (25 μM/24 h) increased oxidative stress in U87MG cells, evidenced by high levels of reactive oxygen species, thiobarbituric acid reactive substance and protein carbonylation. Considering the antitumor effects of BBR in U87MG cells, this compound may be a potential candidate for adjuvant GM treatment.

The aim of the article is to analyze the didactic proposal of Gasparin (2013) from the work titled "A didactic for historical-critical pedagogy", embodied in the methodology proposed by Professor Dermeval Saviani, which addresses this pedagogy as being An alternative to overcoming the liberal approaches of teacher training in recent decades. The work brings the explanation of the five steps of the pedagogical method proposed by Saviani (2011), synthesized in the didactics of Joao Luiz Gasparin. As a central question: how to work the pedagogical praxis that promotes the integral education of the students based on the contributions of the didactics of Gasparin grounded in the principles of historical-critical pedagogy (PHC)? The methodology is part of the bibliographic research pertinent to the proposed theme and its epistemological foundations in Marx's historical-dialectical materialism, with a qualitative approach. It seeks as a goal to obtain theoretical knowledge to reach the teaching practice in a historical-critical perspective based on didactic contributions that evidence the feasibility of social transformation of professors and students. The results show that there is a possibility of applying the method that attempts to work the teaching proposal based on the historical-critical pedagogy, thus breaking with the models of liberal approaches and it was also found that through the Socialization of systate knowledge is possible to succeed in integral human formation and social transformation of students. We conclude that in the Gasparin method the teaching work is more dynamic and the dialectical process of practice-theory-practice leads the student to perceive that the contents to be studied establish a relationship with reality and with the totality of social and historical practice.

Diabetes Mellitus (DM) is associated with an increased susceptibility to various infections, which might be attributed to changes in immune response owing to chronic hyperglycemia. Nucleoside triphosphate diphosphohydrolase (NTPDase), 5′-nucleotidase, and adenosine deaminase (ADA) are important enzymes involved in the generation of anti-aggregant and anti-inflammatory microenvironments. The aim of this study was to evaluate the effect of gallic acid (GA) on the hematological parameters and ectonucleotidase activities in platelets, lymphocytes, and serum of diabetic rats. Experimental rats were categorized into 4 groups: (i) control -saline, (ii) control - GA, (iii) diabetic -saline, and (iv) diabetic - GA. One week after induction of DM using streptozotocin (65 mg/kg), GA (30 mg/kg) or saline was orally administered to the rats for 21 days. Our results demonstrated that the concentration of mean corpuscular hemoglobin was decreased, whereas that of red cell distribution was increased in the diabetic group, however, GA could revert these alterations. Moreover, in diabetic rats, GA reverted the increase in ATP and ADP hydrolysis and ADA activity in lymphocytes, and it prevented the increase in NTPDase and ADA activities in platelets. A decrease in ATP hydrolysis and an increase in ADP and AMP hydrolysis were observed in the serum of diabetic rats; however, GA treatment could solely revert changes in ATP hydrolysis. Our study suggests that GA exhibits beneficial effects on immuno- and thrombo-regulatory responses in DM and that these effects may be related to the modulation of purinergic signaling.

Diabetes mellitus (DM) is characterised by hyperglycaemia associated with the increase of oxidative stress. Gallic acid has potent antioxidant properties. The aim of this study was to evaluate the effect of gallic acid on the biochemical, histological and oxidative stress parameters in the liver and kidney of diabetic rats. Male rats were divided in groups: control, gallic acid, diabetic and diabetic plus gallic acid. DM was induced in the animals by intraperitoneal injection of streptozotocin (65mg/kg). Gallic acid (30mg/kg) was administered orally for 21days. Our results showed an increase in reactive species levels and lipid peroxidation, and a decrease in activity of the enzymes superoxide dismutase and delta-aminolevulinic acid dehydratase in the liver and kidney of the diabetic animals (P0.05). Gallic acid treatment showed protective effects in these parameters evaluated, and also prevented a decrease in the activity of catalase and glutathione S-transferase, and vitamin C levels in the liver of diabetic rats. In addition, gallic acid reduced the number of nuclei and increased the area of the core in hepatic tissue, and increased the glomerular area in renal tissue. These results indicate that gallic acid can protect against oxidative stress-induced damage in the diabetic state.
