Studying and analyzing humane endpoints in the fructose-fed and streptozotocin-...
Silva-Reis, R; Faustino-Rocha, Ana I; Silva, J; Valada, A; Azevedo, T; Anjos, L; Gonçalves, L; Pinto, ML; Ferreira, R; Silva, AM; Cardoso, SMThis study assessed a humane endpoint scoring system to detect animal suffering in a rat model of type 2 diabetes. Sprague-Dawley male rats were divided into control and induced (fructose-fed and streptozotocin (STZ) administration) groups. Induced animals drank 10% fructose for 14 days, then received STZ (40 mg/kg) intraperitoneally. Weekly monitoring of body weight, water, and food consumption, 14 parameters ...
Worldwide trends in underweight and obesity from 1990 to 2022: A pooled analysi...
Robinson, L; Roccaldo, R; Rodrigues, D; Rodriguez Perez, MdC; Rodríguez Villamizar, LA; Rodríguez, AY; Roggenbuck, U; Rohloff, P; Rohner, FBackground: Underweight and obesity are associated with adverse health outcomes throughout the life course. We estimated the individual and combined prevalence of underweight or thinness and obesity, and their changes, from 1990 to 2022 for adults and school-aged children and adolescents in 200 countries and territories. Methods: We used data from 3663 population-based studies with 222 million participants that...
Between-devices agreement in obtaining raw bioelectrical parameters after a lif...
Silva, T.; Nunes, CL; Jesus, F; Francisco, R; Teixeira, Vitor Hugo; Sardinha, LB; Martins, P; Minderico, C; Silva, AMIt is unclear if different bioelectrical impedance (BI) devices provide similar results regarding raw parameters [Resistance (R), Reactance (Xc), Phase Angle (PhA), and Impedance (Z)] for the same population/individual undergoing a weight loss intervention. The aim was to evaluate the cross-sectional and longitudinal agreement of raw data obtained by two BI devices in former athletes with overweight/obesity. Fi...
β-heavy-spectrin stabilizes the constricting contractile ring during cytokinesis
Silva, AM; Chan, FY; Norman, MJ; Sobral, AF; Zanin, E; Gassmann, R; Belmonte, JM; Carvalho, AXCytokinesis requires the constriction of an actomyosin-based contractile ring and involves multiple F-actin crosslinkers. We show that partial depletion of the C. elegans cytokinetic formin generates contractile rings with low F-actin levels that constrict but are structurally fragile, and we use this background to investigate the roles of the crosslinkers plastin/PLST-1 and β-heavy-spectrin/SMA-1 during ring c...
Multiple Sclerosis Patient Management During the COVID-19 Pandemic: Practical R...
Cerqueira, J; Ladeira, A; Silva, AM; Timóteo, A; Vale, J; Sousa, L; Arenga, M; Abreu, P; Guerreiro, R; Sá, JThe spread of the COVID-19 pandemic has imposed significant challenges on healthcare provision, requiring changes in the conventional patient management, particularly in chronic diseases like multiple sclerosis (MS). To increase patient safety and reduce the risk of infection, while ensuring an appropriate and regular follow-up, tele-medicine gained prominence as a valid alternative to face-to-face appointments...
Neuromyelitis optica spectrum disorders: A nationwide Portuguese clinical epide...
Santos, E; Rocha, AL; Oliveira, V; Ferro, D; Samões, R; Sousa, P; Figueiroa, S; Mendonça, T; Abreu, P; Guimarães, J; Sousa, R; Melo, C; Correia, IIntroduction: Neuromyelitis optica spectrum disorder (NMOSD) is a rare disorder in which astrocyte damage and/or demyelination often cause severe neurological deficits. Objective: To identify Portuguese patients with NMOSD and assess their epidemiological/clinical characteristics. Methods: This was a nationwide multicenter study. Twenty-four Portuguese adult and 3 neuropediatric centers following NMOSD patients...

Mono- and Dicationic DABCO/Quinuclidine Composed Nanomaterials for the Loading ...
Fernandes, AR; Sanchez-Lopez, E; Santini, A; Santos, T; Garcia, ML; Silva, AM; Souto, EBOil-in-water nanoemulsions (NEs) are considered a suitable nanotechnological approach to improve the eye-related bioavailability of lipophilic drugs. The potential of cationic NEs is prominent due to the electrostatic interaction that occurs between the positively charged droplets with the negatively charged mucins present in the tear film. This interaction offers prolonged NEs residence at the ocular surface, ...
Development and characterization of nanoemulsions for ophthalmic applications: ...
Fernandes, AR; Sanchez-Lopez, E; Santos, T; Garcia, ML; Silva, AM; Souto, EBThe eye is a very complex organ comprising several physiological and physical barriers that compromise drug absorption into deeper layers. Nanoemulsions are promising delivery systems to be used in ocular drug delivery due to their innumerous advantages, such as high retention time onto the site of application and the modified release profile of loaded drugs, thereby contributing to increasing the bioavailabili...
Dabco-customized nanoemulsions: Characterization, cell viability and genotoxici...
Fernandes, AR; Santos, T; Granja, PL; Sanchez-Lopez, E; Santini, A; Garcia, ML; Silva, AM; Souto, EBQuaternary derivatives of 1,4-diazabicyclo[2.2.2]octane (DABCO) and of quinuclidine surfactants were used to develop oil-in-water nanoemulsions with the purpose of selecting the best long-term stable nanoemulsion for the ocular administration of triamcinolone acetonide (TA). The combination of the best physicochemical properties (i.e., mean droplet size, polydispersity index, zeta potential, osmolality, viscoel...
