Gelatin-based ballistic gel formulated with phytosynthesized nanocellulose from...
Jeevanandam, Jaison; Castro, Rita; Rodrigues, João; Castro, Rita; Rodrigues, JoãoArundo donax, an indigenous plant in the Mediterranean region, has affected the growth of native vegetation as an invasive plant, ultimately reducing soil quality and affecting the food chain in several areas of the world. Thus, the present work aims to obtain cellulose from the A. donax leaf extract via organosolv fractionation and bleaching method, followed by centrifugal fractionation to yield nanocellulose ...
Sustainable synthesis of bionanomaterials using non-native plant extracts for m...
Jeevanandam, Jaison; Rodrigues, João; Rodrigues, Joãolternative approach to synthesizing less or nontoxic nanomaterials, compared to conventional physical and chemical approaches. Among these biological methods, plant-mediated approaches (phytosynthesis) are reported to be highly beneficial for large-scale, nontoxic nanomaterial synthesis. However, plant-mediated synthesis of nanomaterials using native plant extract can lead to bioprospecting issues and deforesta...
Sodium Bicarbonate In In-Hospital and Out-of-Hospital Cardiac Arrest: A Systema...
Batarda Sena, Pedro Manuel; Rodrigues, João; Neves Coelho, Francisco; Soares Nunes, Brenda; Fernandes, Orlando; Fernandes, Nicodemos; Nóbrega, José JCardiac arrest is a common cause of death worldwide. Sodium bicarbonate (SB) has commonly been used during cardiopulmonary resuscitation (CPR) to correct metabolic acidosis (MA). However, the existence of evidence about its administration remains controversial. This systematic review aimed to summarize the effectiveness of SB in patients with in-hospital and out-of-hospital cardiac arrest. We searched Medline, ...
Phenotypic and Genotypic Characterization of Escherichia coli and Salmonella sp...
Gonçalves, Carlota; Silveira, Leonor; Rodrigues, João; Furtado, Rosália; Ramos, Sónia; Nunes, Alexandra; Pista, ÂngelaBackground: Foodborne diseases are a serious public health concern, and food-producing animals are a major source of contamination. Methods: The present study analysed Escherichia coli and Salmonella spp. isolated from faecal samples of 100 fattening pigs and from 52 samples of pork meat. Results: The results showed that the majority of the analysed meat samples were considered satisfactory in terms of microbio...
Assessing carbohydrate counting accuracy: current limitations and future direct...
Amorim, Débora; Miranda, Francisco; Santos, Andreia; Graça, Luís C. C.; Rodrigues, João; Rocha, Mara; Pereira, Maria Aurora; Sousa, ClementinaDiabetes mellitus is a prevalent chronic autoimmune disease with a high impact on global health, affecting millions of adults and resulting in significant morbidity and mortality. Achieving optimal blood glucose levels is crucial for diabetes management to prevent acute and long-term complications. Carbohydrate counting (CC) is widely used by patients with type 1 diabetes to adjust prandial insulin bolus doses ...

Lagos ornamentais como reservatórios de microrganismos resistentes a antimicrob...
Rodrigues, João; Matias, Rui; Jordão, LuísaOs espaços verdes nas grandes cidades têm ganho uma importância crescente para a qualidade de vida e saúde da população. Os lagos e fontes ornamentais presentes nestes espaços são muito atrativos, mas podem esconder alguns perigos. Neste estudo foi avaliada mensalmente durante um ano a flora bacteriana (planctónica e organizada em biofilmes) presente num lago ornamental de um parque urbano situado em Lisboa (Po...
Aeromonas spp. in Freshwater Bodies: Antimicrobial Resistance and Biofilm Assembly
Nascimento, Maria; Rodrigues, João; Matias, Rui; Jordão, LuisaAeromonas spp. are environmental bacteria able to infect animals and humans. Here, we aim to evaluate the role of biofilms in Aeromonas persistence in freshwater. Aeromonas were isolated from water and biofilm samples and identified by Vitek-MS and 16S rRNA sequencing. Antibiotic susceptibility profiles were determined according to EUCAST, and a crystal violet assay was used to assess biofilm assembly. MTT and ...
Epidemiological and clinical aspects of Cutaneous and Mucosal Leishmaniases in ...
Rocha, Rafael; Conceição, Cláudia; Gonçalves, Luzia; Carvalho, Ana Cláudia; Maia, André; Martins, André; Carujo, António; Maio, António; Forra, CatarinaLeishmania infantum, a zoonotic vector-born parasite, is endemic in the Mediterranean region, presenting mostly as visceral (VL), but also as cutaneous (CL) and mucosal leishmaniasis (ML). This study aimed to describe the epidemiological and clinical aspects of the CL and ML cases diagnosed in mainland Portugal between 2010 and 2020. Collaboration was requested from every hospital of the Portuguese National Hea...
Enhanced alpha-amylase inhibition activity of amine-terminated PAMAM dendrimer ...
Jeevanandam, Jaison; Gonçalves, Mara; Castro, Rita; Gallo, Juan; Bañobre-López, Manuel; Rodrigues, João; Gonçalves, Mara; Castro, Rita; Rodrigues, JoãoThe present work aims to prepare copper-doped MgO nanoparticles via a sol-gel approach and study their antidiabetic alpha-amylase inhibition activity with undoped MgO nanoparticles. The ability of G5 amine terminated polyamidoamine (PAMAM) dendrimer for the controlled release of copper-doped MgO nano particles to exhibit alpha-amylase inhibition activity was also evaluated. The synthesis of MgO nanoparticles vi...
