Polyhydroxybutyrate (PHB) is a biodegradable polymer, and preparation of a blend with another biodegradable polymer, polybutylene adipate terephthalate or Ecoflex® (ECO) is described. Some works in the previous literature show the possibility of preparing blends involving both. The techniques normally used previously described normally an extrusion process or even mixers that require high investment such as HAAKE Rheomix, for example. The main contribution is use of an original and simple techni...

O isolamento da lignina presente no bagaco de cana-de-acucar vem sendo amplamente pesquisado, primeiramente devido ao alto volume de bagaco de cana-de-acucar gerado no territorio brasileiro, e em segundo, devido a lignina ser a principal materia-prima de fonte aromatica do mundo, o que indica um material potencial para a substituicao dos recursos fosseis. O presente estudo teve como objetivo isolar e caracterizar a lignina presente no bagaco de cana-de-acucar pelo metodo de polpacao acetossolve....

Background: Lupus nephritis (LN) is one of the most severe manifestations of Systemic Lupus Erythematosus. Objectives: 1) To compare proliferative (PLN), membranous (MLN) and mixed LN regarding clinical and laboratory presentation. 2) To investigate predictors of progression to chronic kidney disease (CKD). Methods: Multicentre observational study, with retrospective analysis of a prospective cohort, using data from the Portuguese registry of rheumatic diseases – Reuma.pt. Patients with biopsy-p...

Background: Patient registries are a valuable tool to monitor a patient’s health status. However, these systems operate primarily from the healthcare provider (HCP) perspective, which makes it difficult to collect detailed information on the nature, frequency and personal impact of adverse drug reactions (ADRs). Objectives: Determining whether the distribution of patient-reported ADRs attributed to bDMARDs differs from ADR registrations by HCPs. Methods: Patient reported ADRs were derived from t...

Background Rheumatoid Arthritis (RA) is a chronic inflammatory disease that has a major impact on patients’ quality of life. The Rheumatoid Arthritis Quality of Life Questionnaire (RAQoL) is a patient-centric outcome measure, specific to RA. The measure has not previously been available for use with Portuguese RA patients. Objectives To produce a Portuguese version of the RAQoL that is acceptable to Portuguese patients and demonstrates sound psychometric properties. Methods The dual panel method...
