Título: Efeitos da auriculoterapia em universitários com estresse, sintomas ansiosos e ou depressivos: estudo multimétodos Abstact: INTRODUCTION: Auriculotherapy, recognized by the World Health Organization and incorporated into the Brazilian Unified Health System as one of the Integrative and Complementary Health Practices, is based on Traditional Chinese Medicine to treat physical and emotional imbalances. It acts on specific points of the ear to alleviate symptoms such as stress, anxiety, and depression. It is a low-cost, non-invasive method with lacks randomized studies focused on young people, such as university students, to verify evidence of effectiveness. OBJECTIVE: To compare the effects of the auriculotherapy protocol on the outcomes of symptoms of depression, anxiety, and stress in a group of students who received the Shen protocol and the Sham protocol (placebo). METHODOLOGY: This is a randomized controlled clinical trial, conducted at a public university in the interior of Maranhão, from November 2024 to October 2025, involving volunteer students, divided into a case group and a control group, with ten (10) sessions held once a week, blinding the participant to the protocol they would receive, with pre- and post-intervention assessment using symptom assessment instruments for depression, anxiety and stress. RESULTS AND DISCUSSION: 117 participants were recruited, but only 78 completed all stages. A significant reduction in mean scores for anxiety, depression and stress was observed in the case group (p<0.001). The control group showed improvement for anxiety and depression, but not for stress. There was a decrease in severe levels of anxiety and depression and an increase in mild and moderate classifications after the intervention. Stress showed more consistent improvement only in the group subjected to the Shen protocol. CONCLUSION: The current challenge of promoting mental health for young people, especially university students, finds in auriculotherapy a possibility for mitigating stress in the academic environment. Furthermore, institutional strategies for early screening, psychosocial support, and mental health promotion programs for this population are also necessary

Análise da suscetibilidade de Cryptococcus neoformans isolados das fezes de Columba livia no município de Caxias Maranhão

Título: Análise da suscetibilidade de Cryptococcus neoformans isolados das fezes de Columba livia no município de Caxias Maranhão Abstact: The Columba livia was introduced in Brazil around the sixteenth century, being considered a domestic species and, because it has synanthropic characteristics, it easily becomes a reservoir of pathogens, and an important source in the chain of transmission of pathogens, as cryptococcosis, which has as its etiological agent the Cryptococcus neoformans or Cryptococcus gattii, however, in a lower frequency. Globally, cryptococcosis recurrences are observed during maintenance therapy, and limited access to drugs facilitates the adaptation of these microorganisms to antifungal agents. In the development of new antifungal drugs, medicinal plants have been highlighted, with research pointing out the fungicidal potential of several species, including some typical of the Brazilian Cerrado region. This research aimed to analyze the susceptibility of environmental isolates of C. neoformans obtained from feces of C. livia, against crude plant extracts and antifungal agents. The study population was composed of feces of Columba livia, collected in urban environments in the city of Caxias, Maranhão. The fungal isolates were identified phenotypically by biochemical tests and microscopy. The tests of sensitivity to plant extracts were carried out using the technique of diffusion in agar Müeller-Hinton, while the tests with antifungal agents were performed using the disc diffusion technique. Of the 36 stool samples collected from C. livia, 69.44% showed growth of colonies of the fungus. The susceptibility tests of C. neoformans strains against raw plant extracts showed variable sensitivity. Extracts A and B were effective in controlling the strains of C. neoformans, and a high number of strains of C. neoformans resistant to amphotericin B and itraconazole was observed. Thus, it was demonstrated that environments in which there are deposits of C. livia excreta, especially in urban areas with human flow are sources for the growth and dissemination of Cryptococcus neoformans. The fungal strains presented a pattern of resistance and susceptibility varied in relation to raw plant extracts and antifungals.

Biodiversidade de formigas (hymenoptera:formicidae) em uma área de caatinga no município de Cristino Castro, Piauí, Brasil

Título: Biodiversidade de formigas (hymenoptera:formicidae) em uma área de caatinga no município de Cristino Castro, Piauí, Brasil Abstact: Brazil is endowed with a rich biodiversity, which is subject to various forms of impacts, which consequently threaten this biodiversity. Thus, the Caatinga, which is a genuinely Brazilian biome, has been suffering over the years with anthropic actions, which has been affecting its fauna and flora, of which there is little information. Given this, this work aims to characterize the community of ants that occur in a Caatinga area in southern Piaui. Using pitfall traps and arboreal traps with bait and without. Two plots were selected, one to be managed and the other to control the ecological patterns. The results obtained were 2,528 specimens, 40 species distributed in eight subfamilies. With the most representative subfamilies Myrmicinae and Formicinae. Therefore, this work is extremely important because it contributed to the knowledge of the epigeic and arboreal myrmecofauna of the Caatinga biome in southern Piauí.

Bacillus thuringiensis: uma análise da produção científica, e estudo sobre fatores abióticos de solos do cerrado na sua abundância e susceptibilidade para larvas de Aedes aegypti

Título: Bacillus thuringiensis: uma análise da produção científica, e estudo sobre fatores abióticos de solos do cerrado na sua abundância e susceptibilidade para larvas de Aedes aegypti Abstact: In the literature in the last 20 years of articles have been published studies related to insect control using different species of bacteria. Therefore, there is a tendency to think that few researchers still dedicate their studies to Bacillus thuringiensis. However, in the present study an analysis of scientific production in the last 20 years was carried out, relating Bacillus thuringiensis to insect control. The overview of the literature showed that research involving this bacterium remained as a line of research of interest to the scientific community. In the two decades of research, the works had different nuances, in the first one, for example, they went deeper into finding new strains. The articles from the second decade, on the other hand, sought to carry out applications, such as the effectiveness of bioinsecticide based on Bacillus thuringiensis in relation to plant extracts (Kovendan, et. al. 2012). It was observed that many studies are conducted in different countries and that many of them have a high rate of publications. As for the purpose of the publications, in 20 years most researches are aimed at exploring and knowing about the properties of Bt, without resulting in a direct application to solve a problem.
