Exploring Disulfiram's Anticancer Potential: PLGA Nano-Carriers for Prolonged Drug Delivery and Potential Improved Therapeutic Efficacy.

Disulfiram (DS) has been shown to have potent anti-cancer activity; however, it is also characterised by its low water solubility and rapid metabolism in vivo. Biodegradable polylactic-co-glycolic acid (PLGA) polymers have been frequently employed in the manufacturing of PLGA nano-carrier drug delivery systems. Thus, to develop DS-loaded PLGA nanoparticles (NPs) capable of overcoming DS's limitations, two methodologies were used to formulate the NPs: direct nanoprecipitation (DNP) and single emulsion/solvent evaporation (SE), followed by particle size reduction.

Blended Psychological Interventions for Emotional Disorders in Youth: Acceptability and Intention to Use in a Sample of Portuguese Psychologists.

Introduction: The rise of mental health problems in youth highlights the need for accessible and cost-effective psychological interventions. Blended interventions, which combine face-to-face and online sessions, can be an adequate response to the increase in demands for youth mental health services. Although this can be a promising approach, effective dissemination depends on the professionals´ acceptance.

Parents' acceptability of blended psychological interventions for children with emotional disorders.

Objectives: This study aims to (1) describe parents' knowledge and use of online resources to address children's mental health issues and the family's general internet and technology usage patterns; (2) examine parents' acceptance of blended interventions for children with emotional disorders (ED); and (3) analyse the predictors of parents' intention to use a blended intervention if their children experienced an ED.

Method: The sample included 164 Portuguese parents (95.7 % mothers) of children between the ages of 6 and 13 years who completed an online survey.

Preparation and Characterization of Disulfiram and Beta Cyclodextrin Inclusion Complexes for Potential Application in the Treatment of SARS-CoV-2 via Nebulization.

Disulfiram (DS), known as an anti-alcoholism drug, has shown a potent antiviral activity. Still, the potential clinical application of DS is limited by its low water solubility and rapid metabolism. Cyclodextrins (CDs) have been widely used to improve the solubility of drugs in water.

Next-generation ARIA care pathways for rhinitis and asthma: a model for multimorbid chronic diseases.

Background: In all societies, the burden and cost of allergic and chronic respiratory diseases are increasing rapidly. Most economies are struggling to deliver modern health care effectively. There is a need to support the transformation of the health care system into integrated care with organizational health literacy.

[Time-Trends in Cervical Cancer Mortality in Portugal].

Introduction: The mortality rate due to cervical cancer is higher in Portugal compared to other European countries. This study aimed to evaluate the time-trends in cervical cancer mortality rates observed in Portugal over the last six decades.

Material And Methods: Age-standardized cervical cancer mortality rates reported in Portugal between 1955 and 2014, were collected from the International Agency for Research on Cancer (IARC).

Adherence to treatment in allergic rhinitis using mobile technology. The MASK Study.

Background: Mobile technology may help to better understand the adherence to treatment. MASK-rhinitis (Mobile Airways Sentinel NetworK for allergic rhinitis) is a patient-centred ICT system. A mobile phone app (the Allergy Diary) central to MASK is available in 22 countries.

Primary Sjögren's syndrome prevalence in a major metropolitan area in Brazil.

There has been no previous prevalence study about of Sjögren's syndrome (SS) in Brazil. The aim was to evaluate the SS prevalence in a general population in Vitória, ES, Brazil. This was an epidemiological, observational, and cross-sectional study conducted on 1,205 randomized people, aged 18-65 years, who lived in Vitória.

An ent-kaurane-type diterpene in Croton antisyphiliticus mart.

Croton antisyphiliticus is a medicinal plant widely used in the treatment of microbial infections, especially those affecting the genital tract. Crude extract, fractions and pure compound isolated from roots of this species were investigated to validate their antimicrobial activity against Escherichia coli and Staphylococcus aureus. The compound ent-kaur-16-en-18-oic acid was isolated as a major component (0.

Effects of erythrinian alkaloids isolated from Erythrina mulungu (Papilionaceae) in mice submitted to animal models of anxiety.

The effects of acute oral administration of erythrinian alkaloids, i.e. (+)-alpha-hydroxy-erysotrine, erythravine and (+)-11alpha-hydroxy-erythravine isolated from the flowers of Erythrina mulungu were investigated in two animal models of anxiety in mice-the light-dark transition model (LDTM) and the elevated plus-maze (EPM).

Anxiolytic effects of erythrinian alkaloids from Erythrina mulungu.

One new erythrinian alkaloid derivative, (+)-11alpha-hydroxyerythravine (1), and the known (+)-erythravine (2) and (+)-alpha-hydroxyerysotrine (3) were isolated from the flowers of Erythrina mulungu. Their structures were determined by spectroscopic/spectrometric data interpretation of 1H, 13C, and 2D NMR and MS experiments. The relative configuration was established by NOESY analysis, while the conformation adopted by these molecules was evaluated through molecular modeling studies and coupling constants obtained by NMR analysis.
