Genossensores Eletroquímicos de Identificação de Espécies Vegetais: Foco no Cas...
Morais, Stephanie; Pereira, Eduarda; Castanheira, Michelle; Santos, Marlene; Domingues, Valentina; Deleure-Matos, Cristina; Barroso, FátimaNeste trabalho, foram desenvolvidos dois genossensores eletroquímicos descartáveis para a identificação de plantas baseado na reação de hibridização entre duas cadeias de ADN complementares de duas espécies de plantas: Erica arborea (urze) e Castanea sativa (castanheiro). Analisando bases de dados públicas, foram selecionados dois pares de sequências especificamente cortadas e desenhadas para identificar o ADN ...
Warfarin pharmacogenomics: Designing electrochemical DNA-based sensors to detec...
Barbosa, Tiago; Morais, Stephanie L.; Pereira, Eduarda; Magalhães, Júlia M. C. S.; Domingues, Valentina F.; Ferreira-Fernandes, Hygor; Pinto, GiovannyThe CYP2C9 enzyme is involved in the metabolism of warfarin. The CYP2C9 gene harbors several single-nucleotide polymorphisms (SNPs), including CYP2C9*2 (rs1799853), which is known to affect warfarin’s therapeutic response. So, it is important to develop analytical tools capable of genotyping these SNPs to adjust warfarin’s therapeutic outcomes. In this work, an electrochemical DNA-based sensor was constructed a...
Sources of bias when assessing seasonal Influenza vaccine performance: a narrat...
Martins, André Miguel; Juan, Luis Félix Valero; Santos, Marlene; Martins, João PauloThe best way to prevent influenza infection is through vaccination. Evaluating vaccine performance is essentially done through two types of study: clinical trials and the test negative design, an observational study derived from the case control. While in clinical trials the sources of bias are perfectly identified and there are specific tools for assessing them, in test negative design we find very varied sour...
Vitamin K Epoxide Reductase Complex (VKORC1) Electrochemical Genosensors: Towar...
Barbosa, Tiago; Morais, Stephanie L.; Carvalho, Renato; Magalhães, Júlia M. C. S.; Domingues, Valentina F.; Delerue-Matos, CristinaAnticoagulants, including warfarin, are often administered to patients who are exhibiting early symptoms of thromboembolic episodes or who have already experienced such episodes. However, warfarin has a limited therapeutic index and might cause bleeding and other clinical problems. Warfarin inhibits the vitamin K epoxide reductase complex subunit 1 (VKORC1), an enzyme essential for activating vitamin K, in the ...
Ensuring safety in cytotoxic drug preparation: A systematic review of guideline...
Moreira, Fernando; Jesus, Ângelo; Pinho, Cláudia; Santos, Marlene; Serdoura, Mélanie; Cruz, Agostinho; Moreira, Fernando; Jesus, Ângelo; Pinho, CláudiaChemotherapy preparation involves the use of specific techniques and equipment, given the need to maintain preparation sterility and its strict prescribed composition, and avoid occupational exposure to cytotoxic agents. This study aims to identify the most relevant contents for pharmacy professionals' education and training programs and to elucidate the evaluation procedure these professionals should follow wh...
Altered NRF2 signalling in systemic redox imbalance: Insights from non-communic...
Santos, Marlene; Morgenstern, Christina; Santos, MarleneThe balanced activity of the cytoprotective transcription factor NRF2 is central for maintaining redox, metabolic-energetics, and proteome homeostasis, as well as for regulating inflammatory responses, among other functions. Activated NRF2 regulates the expression of hundreds of genes containing antioxidant response elements (AREs) or electrophile response elements (EpRE) in their regulatory regions, often prom...
Efficacy and safety of Tocilizumab in the treatment of Rheumatoid Arthritis: An...
Silva, David; Moreira, Fernando; Santos, Marlene; Moreira, FernandoTocilizumab (TCZ) is a humanized immunoglobulin G1 monoclonal antibody that targets and inhibits the interleukin-6 (IL-6) receptor. As a selective inhibitor of this cytokine, TCZ offers a targeted approach in managing inflammatory conditions. Given its specificity and potential therapeutic benefits, this article aims to provide a comprehensive summary of the efficacy and safety of TCZ in the treatment of RA.
Immunogenicity as a predictor of Influenza vaccine efficacy: A systematic review
Martins, André Miguel; Juan, Luis Félix Valero; Santos, Marlene; Martins, João Paulo; Santos, Marlene; Oliveira Martins, João PauloInfluenza represents a significant burden on global public health, and vaccination is the most effective strategy to reduce it. The large investment in vaccination programs and the need for adjustments in vaccine serotypes are important reasons for evaluating the influenza vaccine’s efficacy every year. Establishing a relationship between immunogenicity data and efficacy is also crucial for predicting the effic...
Pharmacological approaches in Amyotrophic Lateral Sclerosis: A systematic revie...
Tomé, Pedro; Moreira, Fernando; Santos, Marlene; Moreira, Fernando; Santos, MarleneAmyotrophic lateral sclerosis is a progressive neurodegenerative disease that results in the deterioration of neuromuscular connections, with no effective treatment currently available.
A preliminary assessment of a stool-based microRNA profile for early colorectal...
Santos, Daniela A. R.; Eiras, Mariana; Gonzalez-Santos, Miguel; Santos, Marlene; Pereira, Carina; Santos, Lúcio Lara; Dinis-Ribeiro, Mário; Lima, LuísColorectal cancer screening methods are well established worldwide as a fundamental pilar in CRC management, namely through non-invasive faecal occult blood testing. However, the limited sensitivity of faecal occult blood test for detecting precancerous lesions highlights the need to search for alternative tools, such as microRNAs (miRs). The main aim of this study was to identify stoolbased miR profiles for ea...
