    Mestrado de dupla diplomação com a UTFPR, Universidade Tecnológica Federal do ParanáPhilaenus spumarius e Neophilaenus campestris (Hemiptera: Aphrophoridae) são considerados vetores importantes de Xylella fastidiosa, uma bactéria fitopatogénica responsável por doenças severas que afetam diversas culturas agrícolas de elevado interesse económico. A compreensão da dinâmica entre as condições climáticas e a fenologia do desenvolvimento dos insetos é essencial para elucidar os ciclos de vida destes vetores e para a implementação de estratégias sustentáveis que visem mitigar a propagação desta bactéria. O presente estudo teve como objetivo investigar os padrões de eclosão dos ovos das referidas espécies de insetos vetores, bem como analisar a relação destes padrões com as variáveis ambientais de temperatura e humidade em cinco locais distintos no norte de Portugal. Indivíduos adultos foram capturados em campo, e em laboratório foram mantidos em caixas de cria com Medicago sativa e agulhas de pinheiro secas para promover a oviposição. No total, foram registadas três datas distintas de oviposição. As posturas de ovos foram divididas e alocadas em cinco locais experimentais, os quais apresentavam diferentes altitudes e condições de temperatura e humidade, incluindo ambientes controlados em estufas e ambientes semicampo. Os resultados demonstraram que a emergência das ninfas variou significativamente entre os diferentes locais e datas de oviposição. Philaenus spumarius apresentou uma emergência prolongada em condições controladas, enquanto N. campestris exibiu um padrão de emergência mais concentrado. Nos ambientes semicampo, a eclosão das ninfas ocorreu principalmente em fevereiro de 2024. A análise dos dados meteorológicos revelou que a temperatura e a humidade influenciaram diretamente a eclosão das ninfas, com variações marcantes observadas entre os diferentes locais. Conclui-se que a relação entre a fenologia do desenvolvimento ninfal e as condições climáticas é complexa e variável, dependendo de múltiplos fatores ambientais. A variabilidade nas datas de emergência sublinha a necessidade urgente de desenvolver ferramentas preditivas que possam auxiliar no controlo eficaz de P. spumarius e N. campestris. Estes resultados são fundamentais para o desenvolvimento de estratégias de gestão integrada de pragas, promovendo uma abordagem mais holística e sustentável na luta contra a disseminação de X. fastidiosa.Philaenus spumarius and Neophilaenus campestris (Hemiptera: Aphrophoridae) are considered important vectors of Xylella fastidiosa, a phytopathogenic bacterium responsible for severe diseases affecting various agricultural crops of high economic interest. Understanding the dynamics between climatic conditions and the phenology of insect development is essential for elucidating these vectors' life cycles and implementing sustainable strategies to mitigate the spread of this bacterium. This study aimed to investigate the hatching patterns of the eggs of these insect vector species and analyze the relationship of these patterns with environmental variables of temperature and humidity at five distinct locations in northern Portugal. Adults were captured in the field and maintained in laboratory-rearing cages with Medicago sativa and dried pine needles to promote oviposition. A total of three distinct oviposition dates were recorded. The egg masses were divided and allocated to five experimental locations, which had different altitudes and conditions of temperature and humidity, including controlled environments in greenhouses and semi-field environments. The results demonstrated that the emergence of nymphs varied significantly among the different locations and oviposition dates. Philaenus spumarius exhibited prolonged emergence under controlled conditions, while N. campestris showed a more concentrated emergence pattern. In the semi-field environments, nymph hatching primarily occurred in February 2024. The analysis of meteorological data revealed that temperature and humidity directly influenced nymph emergence, with marked variations observed among the different locations. It is concluded that the relationship between nymphal development phenology and climatic conditions is complex and variable, depending on multiple environmental factors. The variability in emergence dates underscores the urgent need to develop predictive tools that can assist in the effective control of P. spumarius and N. campestris. These results are fundamental for developing integrated pest management strategies, promoting a more holistic and sustainable approach in the fight against the spread of X. fastidiosa.Este trabalho foi financiado pelo Projeto XVectors.pt: “Biology of xylem-sap feeding insect vectors and potential vectors of Xylella fastidiosa in Portugal” (GP/EFSA/ALPHA/2021/07) e por fundos nacionais através da FCT/MCTES (PIDDAC): CIMO, UIDB/00690/2020 (DOI: 10.54499/UIDB/00690/2020) e UIDP/00690/2020 (DOI: 10.54499/UIDP/00690/2020); e SusTEC, LA/P/0007/2020 (DOI: 10.54499/LA/P/0007/2020)

    This investigation evaluates the valorization of citrus peels (lemon, tangerine, and orange) to recover both on-polar and polar fractions simultaneously. Citrus essential oils, abundant in limonene (74.4–33.7 %), exhibited great antioxidant activity (IC50 = 2.002 mg/mL) and Campylobacter jejuni halo inhibition (2.9 cm), particularly in tangerine and orange essential oils. The aqueous extracts were rich in quinic and malic acid (10–78.8 g/100 g), along with polyphenols (22.7–5.2 mg/g), such as diosmetin, luteolin, and eriodictyol glycosides. Tangerine’s aqueous fraction showed the highest inhibition of oxidative hemolysis (IC50 = 102 μg/mL) and Staphylococcus aureus (MIC = 2.5 mg/mL). Whereas lemon was most effective against lipid peroxidation (IC50 = 1.33 mg/mL) and gastric adenocarcinoma proliferation (IG50 = 83 μg/mL). Principal component analysis correlated the in vitro bioactivities with each compound and citrus type, underscoring the potential of citrus peels as a cost- effective, sustainable source of value-added compounds with tailored commercial applications.The results are part of the grant PID2023-149424OB-I00, funded by MCIU/AEI/10.13039/501100011033 and ESF+.

    This study aims to analyse consumer preferences in the iberian Peninsula by comparing two important european Union-producing countries. in order to be able to make valid cross-cultural comparisons, we used the Best-Worst Scaling (BWS) methodology. We also performed segmentation using latent cluster analysis (lca), including all consumers analysed, regardless of country of origin, to obtain three different segments. comparing both consumers, the significant differences obtained refer to the quality-price ratio, willingness to pay and attributes considered at the time of purchase of olive oil. owing to the BWS methodology, we observe that the number of attributes that establish significant differences between the three segments (taste, brand name and packaging) is higher than in the analysis performed by country (brand name). The 3 segments obtained (“Type-experience consumers,” “external cues consumers” and “Taste seekers”) prioritise the proposed attributes differently and there are significant differences between them in terms of olive oil consumption (place of purchase and average weekly consumption). These conclusions have implications at the business level for the design and development of marketing strategies in the olive oil sector in both countries

    Valorization of Solanum melongena L. crop by-products: Phenolic composition and in vitro antioxidant, antidiabetic, anti-inflammatory, cytotoxic, and antimicrobial properties

    Get PDF
    This study explored the valorization of post-harvest eggplant aerial parts as a sustainable source of value-added ingredients by investigating their phenolic composition and in vitro bioactive properties. HPLC-DAD-ESI/MSn analysis identified chlorogenic acid derivatives as the predominant phenolic compounds (53 % of the phenolic fraction), followed by O-glycosylated kaempferol and quercetin. The extract displayed antioxidant activity in physiologically relevant cell-based assays and significant α-glucosidase inhibitory capacity that far exceeded that of the standard drug acarbose. It also inhibited the formation of advanced glycation end-products (AGEs), suggesting its potential to mitigate diabetes-related complications. Furthermore, the extract showed a modest pancreatic lipase inhibitory effect and capacity to suppress interleukin 6 production. Selective cytotoxicity against human gastric and colon adenocarcinoma cell lines and strong antimicrobial activity against foodborne pathogens were observed. Given the growing demand for natural alternatives to synthetic drugs, these findings position eggplant crop biomass as a promising, sustainable source of active compounds with potential applications in food, nutraceutical, and pharmaceutical formulations for managing type 2 diabetes and other oxidative stress-mediated conditions. This study not only contributes to the valorization of agricultural waste but also expands the research on by-products of Solanaceae crops, offering a pathway for sustainable resource utilization.The authors are grateful to the Foundation for Science and Technology (FCT, Portugal) for financial support through national funds FCT/MCTES (PIDDAC) to CIMO (UIDB/00690/2020 and UIDP/00690/2020), SusTEC (LA/P/0007/2021) and CBQF (UIDB/50016/2020).

    This study analyzed the kinematics and muscle activity during the stand-up paddleboarding (SUP) under different visual focus points in three conditions: i) eyes on the board nose, ii) looking at the turn buoy, and iii) free choice. Methods: Fourteen male paddleboarders (24.2 ± 7.1 years) performed three trials covering 65 m, and the electromyographic (EMG) activation patterns and kinematic parameters in four cycle strokes for the left and right sides were analyzed. Surface EMG of the upper trapezius, biceps brachii, triceps brachii, tibialis anterior, and gastrocnemius medialis were recorded. The data were processed according to the percentage of maximum voluntary contraction (%MVC). Speed, stroke frequency (SF), stroke length, and stroke index (SI) were analyzed. Results: The speed, SF, and SI (p < 0.01, η2 ≥ 0.42) showed significant variance between conditions, with the free condition achieving the highest speed (1.20 ± 0.21 m/s), SF (0.65 ± 0.13 Hz) and SI (2.25 ± 0.67 m2 /s). This condition showed greater neuromuscular activity, particularly in the triceps brachii during both the left (42.25 ± 18.76 %MVC) and right recoveries (32.93 ± 16.06 %MVC). During the pull phase, the free choice presented higher biceps brachii activity (8.51 ± 2.80 %MVC) compared to the eyes on the board nose (6.22 ± 2.41 %MVC; p < 0.01), while showing lower activity in the triceps brachii (10.02 ± 4.50 %MVC vs. 16.52 ± 8.45 %MVC; p < 0.01) and tibialis anterior (12.24 ± 7.70 %MVC vs. 17.09 ± 7.73 %MVC; p < 0.01) compared to looking at the turn buoy. Conclusion: These results suggest that a free visual focus allows paddleboarders to enhance their kinematics and muscle activation, highlighting the significance of visual focus strategies in improving both competitive and recreational SUP performance.This work was supported by National Funds by FCT-Foundation for Science and Technology under project number UI/04045 and grant number BIPD/UTAD/7/2023.

    Bioactivity of honey: phenolic composition, antioxidant trends and carcinoma cell lines effects through digestion

    Get PDF
    Honey is not only a food source but also a valuable substance for health and medicine, owing to its complex composition and bioactive properties. However, there is very limited information on the changes in the active compounds of honey during digestion and their antioxidant capacity and effect on cancer cells at the end of digestion. Herein, we investigate the dynamic changes in their bioactive compound composition and antioxidant activity during in vitro gastrointestinal digestion and the effect of digested honey on several cancer cell lines, after determining the antimicrobial and anti-inflammatory effects of mono- and multifloral kinds of honey. The tested raw honey samples exhibited higher anti-inflammatory properties (36 %–80 %) with increasing total phenolic content (78–132 mg GAE/100 g), along with significant antimicrobial activity against E. coli (6–9 mm) and S. aureus (6–14 mm) bacterial species. The findings showed that total phenolic and flavonoid contents increased significantly during digestion, with a peaking value of 258 mg GAE/100 g in the intestinal phase, while TEAC and CUPRAC analysis exhibited variable trends depending on the digestion stage. Moreover, the concentration of compounds such as gallic, syringic, caffeic, p-coumaric, trans-cinnamic acid, and methyl-3,4,5-trihydroxybenzoate identified by HPLC-DAD showed some fluctuations at different stages of digestion. Cyto-toxicity analysis revealed that digested honey samples, particularly those with higher phenolic content, exhibited pronounced antiproliferative effects on cancer cells at higher concentrations, with minimal effects on healthy cells. These findings underscore the importance of honey’s bioactive compounds, their transformation during digestion, and their potential health benefits.The authors would like to thank the Scientific and Technological Research Council of Türkiye (TUBITAK, Project Number: 116O711/CA15136 COST EUROCAROTEN Action and 2211-A National PhD Scholarship Program) for supporting
