In this work, a polymeric blend of polyaniline (PAni) and chitosan (Chi), modified with Sucrose Octaacetate (SOA), was synthesized and characterized using different techniques. The blend was used as an adsorbent to remove Remazol Black (RB) dye from aqueous solutions. The blend was synthesized using the chemical oxidation method with ammonium persulfate as the oxidizing agent.

Solid lipid nanoparticles (SLNs) represent promising nanostructures for drug delivery systems. This study successfully synthesized SLNs containing different proportions of babassu oil (BBS) and copaiba oleoresin (COPA) via the emulsification-ultrasonication method. Before SLN synthesis, the identification and quantification of methyl esters, such as lauric acid and β-caryophyllene, were performed via GC-MS analysis.

The synthesized derivatives were evaluated for anti-inflammatory activity using an ear edema model. Compound 7c, which showed a greater inhibition of ear edema (82%), was further tested for its COX-1/COX-2 inhibitory activity.

If, for instance, there is a moral right to healthcare, it is natural to believe countries should recognize a legal right to healthcare. This article demonstrates that justifying legal rights to healthcare is more difficult than many assume.

One of the obesity treatment options is bariatric surgery, which effectively reduces calorie absorption and total body mass, but its effects on physical activity (PA) levels need to be clarified, considering the protective effect of the PA against cardiovascular disease, independently of the weight loss alone.
Objectives: To carry out a systematic review and meta-analysis of observational studies that evaluated PA in pre- and post-bariatric surgery periods through objective evaluation.

Objective: To investigate the clustering of health risk behaviors (HRB) and its association with demographics, physical exercise, overweight, perception of health, and diseases in Brazilian pregnant people.
Study Design: This is a cross-sectional study using data from the Risk Factor Surveillance System for Non-communicable Chronic Diseases by Telephone Survey (VIGITEL), the main health survey in Brazil.
Methods: We used data on fruit and vegetable consumption, TV time, tobacco, and alcohol abuse in individuals who reported being pregnant (n = 4553).
Zolpidem is a non-benzodiazepine hypnotic drug that works as a positive modulator of Gamma-Amino Butyric Acid-A (GABA-A) receptors, with high selectivity for α1 subunits. Given this selective binding, the drug has a strong hypnotic activity. Social isolation during the SARS-CoV-2 pandemic has contributed to increased rates of anxiety, depression, and insomnia.

View Article and Find Full Text PDFA few epidemiological studies are evaluating the prevalence and mortality rates of Alzheimer's disease, with no one using a nationwide sample of Brazilian elderlies. This study aims to calculate the prevalence of Alzheimer's disease and investigate possible associations with sociodemographic and lifestyle factors and the presence of diseases non-communicable, and the prevalence and mortality for all Brazilian state capitals. This is an ecological design study made with secondary public data provided by the Ministry of Health.

Methods: Data of 718,147 adults from the "Surveillance of Risk and Protection Factors for Chronic Diseases by Telephone Survey" were used. We described the demographic and behavioral variables, and negative binomial regression analyzed the association between exercise and free time sport types and binge drinking adjusted by demographics variables, body mass index status, and television time.

The COVID-19 pandemic prompted chaotic changes in the daily lives of K-12 teachers, resulting in increased stress and other mental health problems. Limited evidence regarding the relationship between physical activity, sleep, and perceived stress among teachers during the COVID-19 pandemic exists. Therefore, the purpose of this study was to investigate the association between physical activity, sleep quality, and perceived psychological stress among teachers during the COVID-19 pandemic.

Areas Covered: Efgartigimod is a human IgG1-derived Fc fragment modified at five residues to increase its affinity for the neonatal Fc receptor by Abdeg technology. Thus, efgartigimod binds to the neonatal Fc receptor and decreases the levels of IgG, including autoantibodies of this isotype.
Background: Medical innovations offer tremendous hope. Yet, similar innovations in governance (law, policy, ethics) are likely necessary if society is to realize medical innovations' fruits and avoid their pitfalls. As innovations in artificial intelligence (AI) advance at a rapid pace, scholars across multiple disciplines are articulating concerns in health-related AI that likely require legal responses to ensure the requisite balance.

Focusing primarily on Health Canada's regulation of medical devices with AI, it examines whether the existing regulatory approach can adequately address general safety concerns, as well as those related to algorithmic bias and challenges posed by the intersections of these concerns with privacy and security interests. It identifies several issues and proposes reforms that aim to ensure that Canadians can access beneficial AI while keeping unsafe products off Canadian markets and motivating safe, effective use of AI products for appropriate purposes and populations.

Although somatropin treatment is well established, the burden of daily injections can lead to poor adherence and quality of life. In this regard, a TransCon human growth hormone (lonapegsomatropin-tcgd) technology was developed to optimize the therapeutic effect of daily somatropin for the treatment of children with growth hormone deficiency.
