1. Honeycomb: a template for reproducible psychophysiological tasks for clinic, laboratory, and home use
Objective: To improve the ability of psychiatry researchers to build, deploy, maintain, reproduce, and share their own psychophysiological tasks. Psychophysiological tasks are a useful tool for studying human behavior driven by mental processes such as cognitive control, reward evaluation, and learning. Neural mechanisms during behavioral tasks are often stu

2. Association between bone mineral density and content and physical growth parameters among children and adolescents diagnosed with HIV: a cross-sectional study
ABSTRACT BACKGROUND: During childhood and adolescence, there are significant increases in bone mineral content (BMC) and bone mineral density (BMD). OBJECTIVE: To investigate physical growth parameters associated with BMD and BMC among children and adolescents diagnosed with human immunodeficiency virus (HIV). DESIGN AND SETTING: Cross-sectional study con

3. Epidemiological data on HIV-infected patients and the importance of education regarding the infection rate. An analytical cross-sectional study
Abstract BACKGROUND: Sexually transmitted diseases (STIs) are an important public health problem in all countries. Knowledge of their relationship with the various socioeconomic levels is necessary for an understanding of their epidemiology and behavior in society. OBJECTIVE: To investigate the epidemiology of human immunodeficiency virus (HIV)-positive pa

4. Clinico-epidemiological profile of patients at children’s psychosocial care centers in São Bernardo do Campo: a cross-sectional study
ABSTRACT BACKGROUDS: Child and Adolescent Psychosocial Care Centers (Centros de Atenção Psicossocial, CAPSI) are dedicated centers for persistent psychiatric disorders, which provide an individualized therapeutic approach based on extra-hospital services. OBJECTIVES: We aimed to describe the clinico-epidemiological profiles of the patients seeking interv

5. Synthesis, Characterization, Spectroelectrochemical, Photophysical and HSA-Binding Properties of Novel and Versatile meso-Tetra(4-pyridylvinylphenyl)porphyrins Coordinated to Ruthenium(II)-Polypyridyl Derivatives
The free-base meso-tetra(4-pyridylvinylphenyl)porphyrin (1a) and its zinc(II) complex were synthesized and then functionalized with [Ru(bpy)2Cl]+ units (2a and 2b) via conventional methods and evaluated in terms of photophysical, electrochemical and biological aspects. All porphyrins present moderate singlet oxygen production and fluorescence quantum yield,

6. Negative early life experiences as risk factors for suicidal behavior in bipolar disorders
Ultrafiltration coupled with liquid chromatography-mass spectrometry (LC-MS) was established to screen xanthine oxidase (XO) inhibitors from Pueraria lobata root extract. Four compounds were screened out and identified as puerarin, daidzin, daidzein and genistein with half-maximal inhibitory concentration (IC50) values of 30.8, 5.31, 14.5 and 3.02 µg mL−1

7. BINARY MICELLES (E45S8/F127) FOR QUERCETIN AND GRISEOFULVIN SOLUBILISATION
Micelles have aroused interest due to their ability to assist in the transport of poorly soluble drugs. In this study the mixture of copolymers F127/E45S8 in different proportions (F/ES 30/70, 50/50 and 70/30) was performed to improve the bioavailability of griseofulvin and quercetin. The results of cytotoxicity (MTT assay) revealed that the copolymers F127

8. Challenges and opportunities in the science of research to practice: lessons learned from a randomized controlled trial of a sexual risk-reduction intervention for psychiatric patients in a public mental health system
Objective: Human immunodeficiency virus (HIV) prevention efficacy trials with psychiatric patients have been conducted in research settings in high-resourced countries, establishing short-term efficacy for reducing sexual risk behavior. None has been implemented within systems of care. In the last decade, overcoming this research-to-practice gap has become

9. Will environmental changes in temperature affect the course of COVID-19?
ABSTRACT While the outbreak has reached every region of the world, it is undeniable that countries in the southern hemisphere seem to be less affected, where cases have been reported, these have been imported and travel related. We analyzed the climate temperature from various regions according to their current ongoing human-to-human transmission status. We

10. BACTERIAL NANOCELLULOSE BIOMEMBRANE AS A SUPPORT FOR HUMAN INSULIN AIMING AT TRANSDERMAL PERMEATION
Production of bacterial nanocellulose was pursued as a matrix system for the stabilization of human insulin. The biomembranes produced by Gluconacetobacter hansenii were washed with 2% aqueous sodium dodecylsulfate solution, rinsed with ultrapure water and immersed in 1 mol L-1 NaOH aqueous solution at 60 °C for 90 min until neutralization. For the insulin

11. DURABILITY OF HDPE GEOMEMBRANES: AN OVERVIEW
The polymer demand for geotechnical applications has been growing. The geomembrane is a geosynthetic, manufactured, polymeric product and is often specified in environmental projects. Geomembranes started to be used in the 1930s but became more widespread in the 1940s. In the 1970s, geomembranes began to be specified for landfills. Over the past forty years,

12. Differential replicative fitness of the four dengue virus serotypes circulating in Colombia in human liver Huh7 cells
ABSTRACT Dengue has been a significant public health problem in Colombia since the simultaneous circulation of the four dengue virus serotypes. The replicative fitness of dengue is a biological feature important for virus evolution and contributes to elucidating the behavior of virus populations and viral pathogenesis. However, it has not yet been studied in
