Item Hábito alimentar do siri Callinectes ornatus (Ordway, 1863) (Crustacea: Brachyura: Portunidae) na Ilha de Itamaracá, Pernambuco, Brasil(2024-03-08) Silva, Milene Ferreira da; Viana, Girlene Fábia Segundo; http://lattes.cnpq.br/3338076933519392; http://lattes.cnpq.br/5638616005945547The swimming crab Callinectes ornatus (Ordway, 1863) is a crustacean belonging to the Portunidae family of great importance to the benthic community, given its important role in the trophic web of marine environments. The main objective of this study was to identify and provide information about the composition of the diet of C. ornatus Ordway, 1863 at Itamaracá Island, Pernambuco, Brazil in the period after the oil spill that occurred off the Brazilian coast in 2019, as well as to analyze the occurrence of possible changes in its feeding habits. The specimens analyzed came from accompanying fauna from fish collections carried out in August and September 2020. To obtain the material, a 20-meter long, 1.5-meter high trawl with a 5-millimeter mesh opening was used. Two different points were chosen, one in the surf zone at Jaguaribe beach (7°43'43"S 34°49'29"W) and the other at the mouth of the Jaguaribe River (7°43'19"S 34°49'32"W) on Itamaracá Island, Pernambuco, Brazil. After collection, the material was sent to the UFRPE/UAST Benthos Laboratory for analysis. After sorting, the material was identified, measured and sexed to extract the stomachs of the crabs and assess the degree of stomach filling. To analyze the contribution of each food item, the Point Method, the Frequency of Occurrence and the Food Index were applied. Twelve items were identified in the stomachs of the 104 crabs collected at the collection points. The results obtained indicate that Crustacea, Mollusca and Animal Organic Matter were the items that contributed most to the natural diet of the crabs collected in the surf zone of Jaguaribe Beach and Crustacea, Animal Organic Matter and Plant Organic Matter were the items that contributed most to the diet of the crabs collected at the mouth of the Jaguaribe River. As for the difference in the diet of males and females of the species, it was found that there were no major changes in the diet, with only small changes in the proportions of items. However, Crustacea continued to be the most representative item for both sexes. According to these results, the species' feeding habits are characterized as generalist and opportunistic, with a preference for organisms of animal origin. During the analysis of the material, the presence of oily substances was not identified, indicating the presence of oil in its structures or other internal organs, and the comparison with data from the literature shows that there was no change in the species' natural diet, even after the oil incident, with only the presence of plastic waste in some stomachs indicating exposure to anthropogenic activities along the coastal zoneItem Visitantes dos nectários de Desmanthus pernambucanus (l.) Thellung (leguminosae): uma forrageira nativa da Caatinga(2023-09-21) Mello, Fernanda Antônia Gomes de; Silva, Ana Luiza da; http://lattes.cnpq.br/4162831591004569; http://lattes.cnpq.br/1836241097746028Jureminha is a species that occurs in the caatinga biome and has forage potential among other economic importance. The objective of this work was to evaluate the diversity of floral visitors and visitors to the extrafloral nectaries of Desmanthus Pernambucanus and the influence of the visitation of ants (Hymenoptera, Formicidae) on the reproductive success of the species. The work was divided into two stages, which was carried out in the city of Arcoverde-PE from November 2020 to February 2021 and in Serra Talhada-PE. To carry out the experiment, the method described by Campos & Zorzenon was used, where a cone is made of resistant material and placed on the plant together with solid petroleum jelly. The variables measured were: height and diameter of the stem. To determine floral and extrafloral visitors, monthly visits were made to plants in the experimental area of UFRPE-UAST and visitors were collected with the help of an entomological network. The experiment showed that ant influences contribute to the reproductive success of Desmanthus Pernambucanus, but the exclusion of ants favors herbivory and fruit production, interfering with its growth. Few species visited Desmanthus during the study period.Item Radiação eletromagnética UV-C na desinfecção e esterilização microbiológica: uma revisão(2024-03-08) Novaes, Gabriel Frederico; Silva, Ana Luiza da; http://lattes.cnpq.br/4162831591004569The best action to reduce the risks of contamination by pathogenic microorganisms is the use of prevention measures, mainly the hygiene and decontamination of environments, food, objects, among others. Generally, chemical germicides are used to promote such actions, however, this method may not be as efficient. Therefore, new technologies are necessary, one of which is the use of radiation in the shortwave ultraviolet spectrum (UV-C), a method that has been recognized as very effective for decontaminating various surfaces. Therefore, the objective of this work was to record recent applications for microbiological disinfection and sterilization using UV-C electromagnetic radiation, through an Integrative Literature Review. The platforms used to survey the works were: Google Scholar, Web of Science and Virtual Health Library (VHL). The following question was chosen to guide the research: “What are the recent and effective applications of UV-C radiation in the disinfection and sterilization of microorganisms in different areas, and their main advances and challenges?”. After the survey, 525 works were analyzed, of which 100 were selected to be read in full, and, at the end of the analysis, 30 works were included and presented in this review. The results were organized in a synoptic table that presents the synthesis of the selected studies. All the works analyzed presented promising results regarding the inactivation of microorganisms in different contexts using shortwave ultraviolet radiation (UV-C). This review provides a solid basis for implementing UV-C-based disinfection and sterilization practices in a wide variety of scenarios, contributing significantly to preventing the spread of infectious diseases and promoting health security and public health.Item Levantamento do uso de plantas medicinais na cidade de Princesa Isabel – PB(2023-09-19) Torres, Maria José Rodrigues; Ramos, Eduardo Henrique da Silva; http://lattes.cnpq.br/0508987795451323; http://lattes.cnpq.br/4610970204524321Medicinal plants have the ability to treat or cure diseases. The aim of this study was to carry out a survey of medicinal plants in the city of Princesa Isabel - Paraíba. The data was collected through interviews, with questionnaires being applied with personal data and on knowledge of medicinal plants, including only participants aged 18 or over. A total of 40 people were interviewed, of whom 24 species of medicinal plants were mentioned, distributed in 19 families, with Asteraceae, Lamiaceae and Rutaceae being the most represented. The most mentioned species were Mentha crispa L., Plectranthus amboinicus (Lour.) Spreng, Lippia alba Mill and Cymbopogon citratus Stapf. The Use Value (UV) of each species and the Family Use Value (FUV) were calculated. The plants with the highest UV were Cymbopogon citratus with a UV of 0.7, Lippia alba with 0.6 and Mentha crispa with 0.4. The families with the highest FUV were Poaceae and Malvaceae.Item Efeitos biológicos da exposição das larvas Aedes spp., 1762 Linnaeus à luz de led combinada com perturbação sonora(2024-03-01) Souza, Poliana Cachoeira; Gomes Júnior, Plínio Pereira; http://lattes.cnpq.br/4037196872253452; http://lattes.cnpq.br/2125538168490941The Aedes aegypti species, originating from the African continent, has been dispersed worldwide due to the transportation of slaves, becoming a significant vector for viruses causing diseases such as Zika, Chikungunya, and Dengue. Climate change and tourism have increased the spread of these diseases, and efforts to prevent and control mosquito-borne diseases, including Ae. aegypti, involve the use of insecticides, although this practice has not been highly successful in recent decades. Heat, light, and noise pollution are common in urban environments; therefore, this study aimed to analyze the exposure of larvae to LED light of white, green, and blue colors and their interactions with sound vibration waves at 14, 20, and 40 kHz, respectively. Each experimental unit resulted in a different dynamic in the decrease of the number of live larvae over time, with variations in the rate and magnitude of reduction. Blue light + 40 kHz showed a faster and more pronounced decrease in the number of larvae compared to other treatments and the control treatment, followed by Green light + 20 kHz. White light + 14 kHz showed no difference from the control treatment, being the least efficient. Based on these results, this study introduces a new method of controlling Ae. aegypti using natural resources such as light and sound.Item Análise parasitológica de cultivares de uvas (Vitis spp.), comercializadas em diferentes locais na cidade de Serra Talhada, Pernambuco(2024-03-07) Cavalcanti, Amanda de Brito; Lima, Marilene Maria de; http://lattes.cnpq.br/9135077184593725; http://lattes.cnpq.br/2411545060419950Currently, there is an increase in the consumption of fresh foods due to the population's growing search for a healthier diet. However, the quality of these foods in terms of microbiological health is a concern, as they may represent a significant means of transmission of enteroparasites. The present study aimed to investigate the occurrence of parasites in grape samples, sold in different locations in the city of Serra Talhada. The collection period took place between July and December 2023, with the analysis of grape samples (Vitis spp.) carried out at the Plant Biotechnology Laboratory, at the Federal Rural University of Pernambuco. In total, 28 samples of grapes were analyzed from 14 commercial establishments, including greengrocers, street markets and supermarkets. Of the samples analyzed, parasitic structures such as insects, mite eggs and mites were found. Given the results obtained, it was concluded that parasitic structures are present in grapes sold in the city of Serra Talhada, however additional studies are necessary, expanding the sample size and using more than one diagnostic method.Item Crescimento de espécies da Caatinga sob diferentes condições de estresses abióticos(2024-02-15) Moura, Márcia Bruna Marim de; Souza, Luciana Sandra Bastos de; http://lattes.cnpq.br/1186468548787818; http://lattes.cnpq.br/9275493400169999The Caatinga is the largest tropical dry forest in South America and encompasses enormous biodiversity, playing an essential role in ecosystem services. However, anthropogenic pressure has intensified the degradation of the Caatinga's native vegetation cover and soil salinization. The aim of this study was to evaluate the morphological responses of Handroanthus impetiginosus (Mart. ex DC.) Mattos and Handroanthus spongiosus (Rizzini) S. Grose seedling species to the use of natural resources when subjected to the combined stresses of salinity and water deficit. The work was carried out between July 10 and November 20, 2023, inside a nursery located in the Serra Talhada Academic Unit, in the municipality of Serra Talhada-PE. The seeds were sown in a tray and then transplanted into polyethylene bags with a capacity of 8 kg, which were filled with soil and sand in a 2:1 ratio. The plants were arranged in a completely randomized experimental design, with four replications. The species were subjected to three water regimes (RH) based on reference evapotranspiration (ETo): RH1 -50%, RH2- 75% and RH3-100% of ETo, and four salinity levels: N1 - mains water (0.27 dS/m), N2 - 2.52 dS/m, N3 - 6.35 dS/m and N4 - 7.38 dS/m. Biometric data was obtained at 15-day intervals: height (ALT), number of leaves (NF), collar diameter (DC). At the end of the experiments, information on total plant biomass and its partitioning was acquired. The results showed that H. impetiginosus was more tolerant to the conditions analyzed. The species showed greater sensitivity to salt stress, which negatively influenced growth and dry biomass accumulation by up to 98%. Increased water deficit reduced height, collar diameter, number of leaves, root biomass and total biomass. The best performing water table was 100% for both species.Item Atividade inseticida de óleos essenciais de Citrus spp. sobre Sitophilus zeamais em milho armazenado(2023-09-14) Alves, Maria Jéssica Pereira; Oliveira, Carlos Romero Ferreira de; Oliveira, Cláudia Helena Cysneiros Matos de; http://lattes.cnpq.br/1587027736201526; http://lattes.cnpq.br/2515051171734004; http://lattes.cnpq.br/4866960483577818Maize (Zea mays L.) is a cereal of great economic and social value. Its production is a world highlight, but there are significant losses caused by insect attacks. Among the insects that affect stored products, the coleopteran Sitophilus zeamais (Curculionidae) stands out, which causes damaging effects to the grain. In view of the indiscriminate use of synthetic insecticides to control insect pests, alternative methods are being increasingly studied, such as the use of plant compounds, particularly essential oils (EOs). The aim of this study was to assess the toxicity of the EOs of bitter orange (Citrus aurantium), sweet orange (Citrus sinensis), mandarin (Citrus reticulata) and bergamot (Citrus bergamia) on Sitophilus zeamais. The tests were carried out by contact and ingestion in order to estimate the lethal concentrations (LC50 and LC90) of each oil. Once the concentrations had been estimated, the repellency test was carried out with the LC50 on the insect. The four EOs were evaluated in the contact and ingestion test using different concentrations (0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50 µL/20g) for a period of 48 hours, using 10 insects, 20g of maize, in 5 repetitions. In the repellency test, the lethal concentrations (LC50) of the four EOs were applied alone, using 10 insects, 20g of maize, in 10 repetitions, confined for 48 hours. In the contact and ingestion test, the percentages of insect mortality were counted and in the repellency test the insects attracted, as well as the number of adults that emerged in each treatment. In the contact and ingestion test, significant differences were observed at the lowest concentrations, with the most toxic EOs being bitter orange (C. aurantium) and bergamot (C. bergamia). The Repellency Index (RI) showed that the four EOs used had a repellent effect at all the concentrations tested. There was no significant difference in the emergence of S. zeamais on the treated maize kernels, indicating that they acted as oviposition inhibitors and/or had an ovicidal/larvicidal effect. Therefore, it was found that the EOs were promising for the management of S. zeamais in stored grain.Item Nível de conhecimento sobre doação de medula óssea: uma revisão bibliográfica(2023-04-14) Lima, Dayanne Cibele Alves de; Ramos, Eduardo Henrique da Silva; http://lattes.cnpq.br/0508987795451323 País de Nacionalidade Brasil; http://lattes.cnpq.br/9444932050996312The bone marrow is a gelatinous tissue that occupies the interior of the bones, it should be noted that it is in the bone marrow that the components of blood are produced. In view of the importanceof this to the organism, it is emphasized that there are many diseases that can cause the malfunctionof the bone marrow, which may require a Bone Marrow Transplantation (BMT). There are some types of BMT, such as allogeneic, syngeneic and autologous. Under this bias, it is possible that the donor does not have a genetic link with the patient, and can be found based on compatibility through the registration of the future possible donor in the Brazilian Registry of Marrow Donors (REDOME). It is worth noting that there is a need to discuss the topic, because only from knowledge about bone marrow donation is it possible to register more and more people in the donor database, therefore, the choice of topic is justified based on the observation that the theme is discussed especially with higher education students. In this perspective, the general objective ofthis work is: Examine the level of knowledge on the topic of bone marrow donation. While the specific objectives are: To correlate the level of knowledge on the topic of bone marrow donation; Assess whether this topic is socially debated; and observe the knowledge regarding the subject inthe different teaching stages. The method used is a narrative literature review. There was too muchmisinformation on the subject in the various stages of teaching from the perspective of the reviewpresented throughout this work, realizing the need to socially debate about the BMT and the REDOME registration for the purpose of propagating adequate knowledge and, who sá, contributeto increasing the number of registrations for bone marrow donation.Item Distribuição geográfica e status de conservação de espécies de Sebastiania spreng. (euphorbiacea) endêmicas do nordeste do Brasil.(2023-09-19) Magalhães, Thais Nunes; Melo, André Laurênio de; http://lattes.cnpq.br/0908553047440221; http://lattes.cnpq.br/6803077394499902Sebastiania Spreng. is a Neotropical taxon that is part of Hippomaneae, a tribe that has around 33 genera and approximately 300 species. In Brazil, the center of diversity of the genus, it is represented by nine species (S. brasiliensis, S. brevifolia, S. jacobinensis, S. larensis, S. macrocarpa, S. pteroclada, S. riparia, S. subsessilis and S. trinervia of which seven are endemic. The genus is distributed in theextraAmazonian portion of the country, with most species occurring inseasonally dry forests, especially in the caatinga and semi-deciduous forests of the Southeast, Center-West and South, rarely in the Atlantic Forest and, it is common, to be found inthe banks of rivers and streams.The present study aimed to evaluate the geographic distribution of Sebastiania species endemic to Northeast Brazil. This work recorded 3 species distributed across the region's phytophysiognomies, all of which are endemic to the Brazilian Northeast. The species chosen were Sebastiania brevifolia, S. jacobinensis and S. macrocarpa. A data collection was carried out using speciesLink, with the purpose of generating spread sheets with the occurrence data of the selected species. With this data, a map was generated with all the geographic distributions of the selected species using QGIS model 2.18.28. The Northeast regions that presented the highest degree of richness in the number of specimens were Bahia, Pernambuco and Ceará, followed bySergipe, Rio Grande do Norte and Paraíba. Among the species analyzed, S. macrocarpa was the one with the widest distribution, having records in the states of Bahia, Pernambuco, Ceará, Paraíba and Rio Grande do Norte. Sebastiania jacobinensis was distributed in four states (Bahia, Pernambuco, Ceará and Sergipe) and S. brevifolia was distributed in only three states (Bahia, Pernambuco and Ceará). According to their conservation status according to IUCN (2019), S. brevifolia and jacobinensis are considered of little concern due to their range of occurrence and may be considered endangered. S. macrocarpa is now considered tobe of concern, according to IUCN criteria (2019), also presenting it as endangered
