Association between motivation and engagement with changes in cognition and symptoms after digital cognitive training in schizophrenia.

Background: Digital cognitive training can remediate cognitive deficits present in schizophrenia. However, limited motivation and engagement may impact adherence to training. Therefore, identifying factors that may enhance (facilitators) or decrease (barriers) engagement in digital cognitive training and possibly modulate its effects are of great clinical relevance.

What Are the Maternal Factors that Potentially Intervenes in the Nutritional Composition of Human Milk?

Background: To evaluate the potential factors associated with the nutritional composition of human milk of puerperal women.

Methods: cross-sectional study, conducted between March 2016 and August 2017, with 107 women, selected in a Tertiary Health Care Tertiary Health Facility of the Unified Health System (SUS) in the Municipality of Rio de Janeiro. Data were collected two months after delivery.

Do chronic noncommunicable diseases modify the macronutrient composition of human milk?

This study aims to evaluate the impact of excess body weight, diabetes mellitus, and hypertension on the nutritional composition of human milk. This cohort study was conducted at a tertiary public health unit in the city of Rio de Janeiro from March 2016 to February 2018. The data were collected in two stages (96 hours and one month after delivery).

In Vitro Evaluation of Experimental Self-Adhesive Orthodontic Composites Used to Bond Ceramic Brackets.

The aim of this study was to evaluate the degree of conversion (DC), flexural strength (FS), and shear bond strength (SBS) of ceramic brackets bonded to enamel with experimental self-adhesive orthodontic composites. Functional monomers 10-methacryloyloxy-decyl-dihydrogen-phosphate (MDP) and glycerol-dimethacrylate-phosphate (GDMA-P) were used in experimental composites. They were compared to the same composite without an acidic monomer (negative control) and with enamel acid-etching prior to adhesive application (positive control).

Catalytic Properties of Amylolytic Enzymes Produced by Using Agroindustrial Residues on Solid-State Fermentation.

Amylases catalyze the hydrolysis of starch, a vegetable polysaccharide abundant in nature. These enzymes can be utilized in the production of syrups, alcohol, detergent, pharmaceutical products, and animal feed formulations. The aim of this study was to optimize the production of amylases by the filamentous fungus by solid-state fermentation and to evaluate the catalytic properties of the obtained enzymatic extract.

Biosynthesis, characterization and leishmanicidal activity of a biocomposite containing AgNPs-PVP-glucantime.

Aim: Development of functionalized nanocomposites containing AgNPs-PVP-Glucantime to evaluate their leishmanicidal activity as a novel method for improving the pharmacological properties of the drug Glucantime against extracellular promastigotes and intracellular amastigotes of Leishmania amazonensis in vitro to treat cutaneous leishmaniasis.

Materials & Methods: The silver nanoparticles and nanocomposites prepared containing silver nanoparticles, polyvinylpyrrolidone and different amounts of Glucantime were characterized using transmission electron microscopy, x-ray diffraction, energy-dispersive x-ray spectroscopy and ζ potential analysis; in addition, the in vitro cytotoxicity was evaluated.

Results: The nanocomposites showed an inhibitory effect on the cellular viability of promastigote forms, with values of 47.
