Biological aspects of Head and Neck Cancer

2022-11-15T19:49:38-03:00

Cancers are genetic origin pathologies, caused by cell cycle anomalies, with two main groups of genes related to their development: Oncogenes and tumor suppressor genes. Head and neck cancer is the name given to a heterogeneous group of cancers that occur above the collarbone region. These pathologies are aggressive and disfiguring, with a high mortality rate due to late diagnosis. Many risk factors are associated with development of this pathology, being smoker, alcoholism and HPV infection the main. The last one, is so important, that oropharyngeal cancer received a new staging classification for patients HPV-postive and patients HPV-negative. It’s understood that earlier the cancer is diagnosed, better is the cure chance. For that reason, more studies in this area are important.

Forensic Entomology and the importance of entomological collections

2023-07-07T11:52:44-03:00

Entomological collections represent fundamental tools in the study and correct recognition of taxons, recording the species and their geographic distribution, helping in the elaboration of publications destined to the identification of insect groups, development of different technical works and extension activities. The collections stand out as a basis for the studies of biodiversity and evolution, in addition to being invaluable for both researchers and society in general. When well maintained and organized, including a suitable environment and correct management, entomological collections can last for years and thus are extremely important for research. Although the great technological advance that helps in the identification of taxons, the use of collections in routine species identification activities is still necessary. Thus, the present work aimed to carry out a literature review on the importance of entomological collections in the identification of species and application of Forensic Entomology in criminal expertise. With the advancement of forensic studies, the importance of entomological collections was verified, as they help in the identification of insects that visit the corpse, facilitating forensic analysis and contributing data in an investigation.

Peridomestic conditions of urban and rural residences in Petrolina (PE) and the relationship with zoonotic risks

2022-12-07T15:41:43-03:00

Diseases linked to climatic conditions, poverty, deficiency of infrastructure / sanitation and health care, associated with cultural, social and economic factors, are responsible for the incidence and prevalence of zoonoses. The objective was to socioeconomically analyze the population of Petrolina (PE) and characterize the surroundings of the residences, in order to verify exposure to zoonotic risks. This is an observational field study, analytical nature, cross-sectional design, exploratory and descriptive approach, and analysis of the qualitative and quantitative results. 397 people, over 18 years old, residents of the household, in urban and rural areas were interviewed. The interviewees were mostly women (65.5%) and adults (69.5%). Individuals with incomplete elementary education (28.2%) and complete high school (28.9%), among the middle class (58.9%), stood out. In the urban area, they declared residences close to open sewers and land with garbage, while in the countryside, proximity to forests and the river / stream, having sanitation areas. Such variables were statistically relevant. The variable “presence of dogs around the home” was not statistically different, but the population reported seeing stray dogs frequently. The population feels exposed to risk factors.

Use of alternative products to control Ceratocystis frimbriata in kiwi seedlings

2022-10-25T10:57:59-03:00

In the state of Rio Grande do Sul (Brazil) is the largest producer of kiwi, but its productivity has been threatened due to the Ceratocystis fimbriata pathogen. This paper aimed to evaluate the efficiency of essential oils of fennel and Cymbopogon citratus (lemongrass), Pipper nigrum (pepper) and pyrolenous extracts, and Aliette (Fosetyl-Al) fungicide in the control of C. fimbriata on kiwi in vitro and in vivo tests. The treatments for the in vitro test were the following: essential oil of Foeniculum vulgare (fennel) and lemongrass at the concentrations of zero, 0,01 %, 0,05 %, 0,10 %, 0.15 %, and 0.20 % v/v. For pepper extract, the concentrations used were zero, 0,05 %, 0,10 %, 0.25 %, and 0.50 % v/v. For pyroligneous extract, the concentrations used were the following ones: 0,05 %, 0,10 %, 0,25 %, and 0.50 % v/v and fosetyl-Al fungicide (250 g/100 L). The outline was completely randomized with five repetitions, each plot consisting of a Petri dish. For the in vivo assay, seedlings of the cultivar Bruno of one-year-old were used, and they were cultivated in five-liter land pots and kept in a greenhouse. The inoculation occurred through sterilized paper discs, with a diameter of 0.5 cm, immersed in a suspension of the pathogen on a previously provoked injury. The treatments were done through the essential oil of fennel and lemongrass at a dose of 0.20 % and fosetyl-Al (250 g/100 L). The results were submitted to the analysis of variance and the means were compared by the Scott-Knott test with 5 % error probability. It was concluded that the essential oils of lemongrass and fennel, at the concentrations of 0.10, 0.15 and 0.20 % v/v, inhibited completely (100 %) the growth of C. fimbriata. The pepper extract had no effect on the growth of the pathogen at the concentration of 20 % v/v. And for the in vivo assay, no treatment showed satisfactory disease control. however, future studies with higher doses may be carried out.

Technical Evaluation of the Use of Biocidal Additives in Cementitious Composites

2023-09-03T00:17:44-03:00

Although cementitious composites have several applications, they still have limitations in their characteristics, including biodeterioration, due to the action of microorganisms. In order to improve this condition, zinc oxide (ZnO) was added as a biocide additive, in order to add better performance against the action of microorganisms, in addition to pozzolanic materials, rice husk ashes, which, together with the biocide additive, they can improve the mechanical resistance and the absorption of water by capillarity of the cementitious composite. In this study, the properties of cementitious composites with the addition of zinc oxide (ZnO) and rice husk ash (RCA) were evaluated in the fresh and hardened state. Traces were developed, varying the additions, in grams of material, of ZnO at 0%, 5%, 10%, 15% and 20%, in addition to the fixed 10% of CCA, 0.042% of superplasticizer and their w/w ratio. c of 0.5. To evaluate the performance of the cementitious composites, tests were carried out on consistency, resistance to compression and traction in bending, total and partial water absorption by capillarity, in addition to the visual analysis of the biocidal properties. There was great fragility in the samples with the incorporation of the biocide additive, demonstrating a drop in their workability, a reduction in resistance by up to 97% for traction in flexion at 7 days and by up to 98% for compression at 7 days, a water absorption per capillarity three times greater than the reference, as well as a delay in the curing time of the materials. The visual analysis showed little variation in the defined time.

Evaluation of the effect of the application of two types of potassium fertilizers on the production and quality of ungrafted Isabel’ grapes

2023-09-15T10:47:11-03:00

Potassium is a macronutrient responsible for regulating plants' metabolic processes and water balance. In grapevines, this nutrient strongly influences the production and quality parameters of the berries, consequently affecting the quality of the juices and wines produced. Potassium can be supplied differently, impacting vineyard productivity and grape properties. The present study aimed to evaluate the effect of applying two different fertilizers on the production and quality of ungrafted Isabel vines. The experiment was carried out in the 2016/2017 cycle in the Serra Gaúcha region. Three treatments were tested: control without fertilization (T1), addition of 80 kg∙ha^-1 of K₂O in the form of KCl, and addition of 80 kg∙ha^-1 of K₂O as the compound fertilizer form 04-18-08 (N-P-K). Yield per plant, potassium content in leaf petioles, soluble solids, titratable acidity, SS/TA ratio, must pH, and total phenolic compounds and anthocyanins content were determined. The results showed that fertilization did not influence the yield per plant nor the soluble solids content, regardless of the fertilizer used. The application of KCl caused a reduction in the titratable acidity, with a consequent increase in the SS/TA ratio. On the other hand, applying the 04-18-08 fertilizer promoted a growth in the total anthocyanin content and pH without affecting the titratable acidity. According to the results, the studied fertilizers can be used in the vine culture without damage to the productivity of the plants or the quality of the berries. Considering the use of these fruits as a feedstock for wines and juices, the 04-18-08 fertilizer would be an interesting option aiming to increase the contents of bioactive compounds, such as anthocyanins.

Critical review of the movie “The Wave” under the perspective of Idealism and Realism Pedagogies

2023-04-11T09:12:51-03:00

The movie “The Wave” depicts an experiment carried out during Contemporary History lessons in a basic education school. The approach had the objective of demonstrating the motivations that led germans to accept and follow the nazi regimen. For this, the professor made use of an unorthodox methodology which simulated autocratic principles inside the class. In this context, the current paper aims to perform a critical review of the movie “The Wave”, establishing connections between the narrative and the fundamentals of education. Initially, an analysis is conducted to determine relations between events of the film and the two main pedagogical theories: the Idealism of Plato and the Realism of Aristotle. In sequence, a reflection on positive and negative experiences is held, as well as their impact on learning. At last, a discussion is developed on certain elements of the movie and traditional tendencies that permeate the current pedagogical thinking, such as the culture of spectacle, knowledge relativization and, humanistic and technical ideologies. This work allowed the development of critical analyses with respect to the occupation and exercise of teaching and the relationships existing in the school environment.
