Eco-Friendly Management of Root Lesion Nematodes Using Volatile Allelochemicals

Pereira, Gonçalo; Barbosa, Pedro; Vicente, Claudia SL; Faria, JMS

Root lesion nematodes (RLNs) are major plant parasites causing significant global yield losses in a wide range of crops. Current management strategies largely depend on syn- thetic nematicides, which raise environmental and human health concerns due to their broad-spectrum toxicity and persistence in the ecosystem. Volatile allelochemicals offer a promising, environmentally safer alternative due to their biodeg...


Antioxidant Enzymatic Activity of Extracts from Hairy Roots of Root-Lesion-Nema...

Pereira, Gonçalo; Vicente, Claudia SL; Faria, JMS

Diseases caused by phytoparasitic nematodes are still a heavy constraint on modern farming, causing losses in crop yields as well as increased production costs due to pest management. Root-lesion nematodes (RLNs) are soil-dwelling migratory endoparasites that infect the roots of several crop species. RLNs feed and reproduce in the cortical cells of affected plant roots typically characterized by development of ...


The influence of diet supplementation with oat hay and whole carrot on the comp...

Quaresma, Mário A. G.; Pereira, Gonçalo; Nunes, Maria Leonor; Gonçalves, Helena; Bessa, Rui J. B.; Roseiro, Cristina; Alves, Susana P.

Reducing feeding costs without compromising rabbit health, productivity, and meat quality is essential to increase the competitiveness of rabbit meat. This study tested the hypothesis that supplementing rabbits' diet with oat hay and whole carrots, either singly or in combination, does not affect the composition and nutritional quality of the meat's lipid fraction. Eighty rabbits were divided into four groups: ...


BPA analogues affect intestinal barrier integrity and pro-inflammatory response...

Pereira, Gonçalo; Barros, Patrícia; Matos, Paulo; Jordan, Peter

Background: Bisphenol (BP) A and its structural analogues are environmental pollutants with endocrine-disrupting properties and potential immune-modulating effects. Following legal restrictions on the use of BPA, structurally related compounds including BPAP, BPP, and BPS-MAE have been introduced as alternatives; however, their potential hazardous profiles remain largely unknown. Here we used a coculture cell m...


Sequence alignment: Comparative analysis of algorithms in KRAS genetic mutations

Pereira, Ana Rita; Lopes, Carlos; Oliveira, Catarina; Pereira, Gonçalo; Moreira, Rui; Faria, Brígida Mónica; Faria, Brigida Monica

For this study a program was developed in Python on biological sequence alignment, considering the application of algorithms in the genetic analysis of Kristen rat sarcoma viral oncogene (KRAS) and its main mutations associated with cancer. The KRAS gene, like other genes in the same family, is responsible for encoding proteins that regulate cell proliferation, differentiation, and apoptosis. The algorithms emp...


In Vivo and In Vitro Grown Lemon-Scented Gum as a Source of Nematicidal Essenti...

Faria, Jorge M.S.; Pereira, Gonçalo; Figueiredo, Ana Cristina; Barbosa, Pedro

Corymbia citriodora is a eucalypt tree of significant economic value due to its essential oils (EOs), rich in citronellal, citronellol, and other oxygenated monoterpenes with diverse biological activities. Its EOs show potential for the formulation of biopesticides with a lower impact on the environment and human health. This study evaluated the in vitro nematicidal activity of C. citriodora EOs, obtained from ...


Experiência e Representação: Limites e Materialidades da Fotografia de Arquitetura

Pereira, Gonçalo

Dissertação de Mestrado Integrado em Arquitetura apresentada à Faculdade de Ciências e Tecnologia; This research seeks to answer the question of the place of Photography in the different productive stages of the subject of Architecture. We are embedded in a world that is increasingly governed by immersion in the image, a world where we resort to visualization as a means of observing our surroundings. We favor v...


When the solution becomes the problem: a review on antimicrobial resistance in ...

Pires, Ana José; Pereira, Gonçalo; Fangueiro, David; Bexiga, Ricardo; Oliveira, Manuela

Antibiotics' action, once a ‘magic bullet’, is now hindered by widespread microbial resistance, creating a global antimicrobial resistance (AMR) crisis. A primary driver of AMR is the selective pressure from antimicrobial use. Between 2000 and 2015, antibiotic consumption increased by 65%, reaching 34.8 billion tons, 73% of which was used in animals. In the dairy cattle sector, antibiotics are crucial for treat...


Impact of Infrasound Exposure and Streptozotocin-Induced Glucose Intolerance on...

Zagalo, Luísa; Pereira, Gonçalo; Casal, Diogo; Gonçalves, Luísa L; Zagalo, Carlos; Oliveira, Maria João; Oliveira, Pedro; Brito, José A A

The elemental composition of chemical elements can vary between healthy and diseased tissues, providing essential insights into metabolic processes in physiological and diseased states. This study aimed to evaluate the calcium (Ca) and phosphorus (P) levels in the bones of rats with/without streptozotocin-induced diabetes and/or exposure to infrasound. X-ray fluorescence spectroscopy was used to determine the c...


First Insights on Resistance and Virulence Potential of Escherichia coli from C...

Magalhães, Rita; Abreu, Raquel; Pereira, Gonçalo; Cunha, Eva; Silva, Elisabete; Tavares, Luís; Chambel, Lélia; Oliveira, Manuela

Captive birds of prey are often used for pest control in urban areas, while also participating in falconry exhibitions. Traveling across the country, these birds may represent a public health concern as they can host pathogenic and zoonotic agents and share the same environment as humans and synanthropic species. In this work, Escherichia coli from the cloacal samples of 27 captive birds of prey were characteri...
